Abstract Marine biodiversity scientific research in Costa Rica started in the 19th century. I have divided its history into three phases based on the chronology, methods, and focus of the research. The first phase, from the early 19th to the early 20th century, was a time of exploration of the seas worldwide. The first publications

on marine organisms collected in Costa Rica were published in 1832. During this phase, collections for museums were made by ship captains and professional collectors, and by the first expeditions that visited Costa Rica in the late 19th century. The second phase, from 1924 to the 1990s, was a time of intense collection by foreign scientists, mainly from the United States, and especially between 1925 and 1939. Publications based on those collections are still appearing to the present day. The third phase, starting in the early 1970s, sees the contributions of the first Costa Rican marine scientists and resident foreign scientists. The creation of the Marine Sciences and Limnology Research Center (CIMAR) at the Universidad de Costa Rica (UCR) in 1979 is a turning point in marine research in Costa Rica. It is characterized by the publication of papers on many different groups, by ecological studies, and by the collaboration between national and foreign scientists. The importance of a strong local scientific community is emphasized for the generation and the assimilation of new knowledge and collections, and for the dissemination of that knowledge.

Introduction Marine organisms and environments were mentioned in travelers’ descriptions of Costa Rica starting in the 16th century, for example, the use of muricid snails to dye textiles by indigenous populations and the extraction of pearl oysters (Meléndez 1974). Even though these antique records provide interesting information on past environments and organisms, I will concentrate on research about marine animals and plants from Costa Rica that is published in scientific journals. The first scientific publications on the natural history of Costa Rica were from the early 19th century, and were done by visiting or resident foreign “scientists,” most of who were naturalists without formal training (Eakin 1999). This author presents an excellent reconstruction of the first scientific activities in Costa Rica, and covers the creation (1887) and functioning (until 1904) of the Instituto FísicoGeográfico Nacional (National Physical Geographic Institute), the first scientific institution in the country. Peraldo-Huertas (2003) compiled a series of papers on the history of research in Costa Rica during the 19th and early 20th centuries; all these publications were on terrestrial investigations. Marine research in Costa Rica also started in the 19th century, and in this paper I will concentrate on research related to marine biodiversity, i.e., papers with lists of species and description of new species. I have divided the historical development of marine biodiversity scientific research into three phases based on chronology, logistics for doing the collections, and the focus of the research. The first two phases differ in time and, in some cases, in the logistics to obtain the specimens, but all the research was carried out by foreign scientists with their own agendas, and with no connection to local scientists or interests. During the third phase, research was done by both local scientists and resident foreign scientists, and sometimes through collaborative projects with foreign institutions.

From the early 19th to the early 20th century, there were two sources of marine organisms for study and publication. The first source was from ship captains, professional collectors and Costa Rican scientists who sent specimens to foreign specialists, and the second source was from organisms collected during oceanographic expeditions. The first expeditions organized with the sole purpose of scientifically exploring the oceans began in the mid- to late 19th century (e.g., the HMS Challenger Expedition, 1872–1876: Corfield 2003). Towards the end of the 19th century the United States mounted a number of marine scientific expeditions, especially to the Atlantic and eastern Pacific oceans. During these expeditions, large numbers of organisms were collected, and their descriptions published during the following decades. The phase from 1924 to the 1990s was a time of intense collection, especially in the eastern Pacific, by foreign scientists, mainly from the United States, both in organized expeditions and by individuals, most of them funded by philanthropists. Publications based on those collections are still appearing to the present day. The third phase started in the early 1970s with Manuel M. Murillo, the first Costa Rican marine scientist with a Ph.D., and the creation of the Marine Sciences and Limnology Research Center (Centro de Investigación en Ciencias del Mar y Limnología; CIMAR) at the Universidad de Costa Rica (UCR) in 1979. This period is characterized by the publication of papers on many different taxonomic groups, ecological studies, and the collaboration between national and foreign scientists. Also, the focus of the research is more locally oriented.

First Phase: Early 19th to Early 20th Century The first scientific papers on marine organisms from Costa Rica were published by Sowerby (1832) who described species of mollusks collected by Hugh Cuming in Bahía Potrero, Golfo de Nicoya, and Golfo Dulce. Later, Mörch (1859–1861) described more species of mollusks, collected in the Golfo de Nicoya. These collections were done by ship captains or by professional collectors (e.g., Hugh Cuming collected in South and Central America between 1827 and 1830 for British scientists) who sent the specimens to museums in Europe and in the United States. Between 1845 and 1848, marine specimens were collected in the West Indies and Central America, and from those collections the first sipunculid from Costa Rica was described, with specimens from Puntarenas (Grube 1859). Another early contribution was by A.E. Verrill who described six species of octocorals and one species of scleractinian coral, all collected in the Golfo de Nicoya by J.A. McNeil (Verrill 1870). Resident foreign scientists, like Paul Biolley, and Costa Rican scientists, like José Fidel Tristán, sent specimens between 1902 and 1907 to the United States National Museum (USNM) in Washington, DC, and several new species were described (Stebbing 1903, 1906; Rathbun 1906). Henri Pittier, a Swiss scientist who lived in Costa Rica from 1887 to 1904, also sent marine organisms to the US National Museum (Rathbun 1930).

Towards the end of the 19th century and early in the 20th century, there were six expeditions that visited Costa Rican waters, specifically Isla del Coco (Cocos Island) (Table II.1), all of them but one were funded by government institutions. The first scientific expedition to the region was in 1888 with the US Fish Commission Steamer Albatross (Fig. II.1) and led by Alexander Agassiz (Fig. II.2). During that occasion four stations south of Isla del Coco were sampled in 1 and 2 April, and hydrographic data recorded; but in only one of the stations, a few samples were collected using scoop nets and electric lights (Townsend 1901). Apparently they stopped at Isla del Coco, because two species of snails collected from the beaches of the island are reported in the only reference in which specimens from Costa Rica are mentioned (Dall 1900). The next major expedition made significant contributions to the knowledge of marine biodiversity of the region: the US Fish Commission Steamer Albatross 1891 Expedition to the west coast of Central America and the Galapagos, again led by Alexander Agassiz (Faxon 1895; Townsend 1901). The Steamer Albatross 1891 Expedition was in Costa Rican waters from 26 February to 2 March 1891, and 15 stations were sampled, most were around Isla del Coco. Dredging and trawling was done at 12 stations (stations number 3362–3373), hydrographic soundings at three additional stations, six surface tow-net stations (where dredging was also done), and six serial temperature stations, with records from the surface to the bottom, ranging from 29.9 °C to 2.5 °C (Townsend 1901). Many papers were published and new species described (Cortés in preparation), including the only paper on sponges from the Pacific of Costa Rica (Wilson 1904). Towards the end of the 19th century the Instituto Físico-Geográfico Nacional de Costa Rica (IFGN, National Physical-Geographical Institute) was created by the resident Swiss scientists Henri Pittier. One of the objectives of this institute was the scientific study of natural history in Costa Rica (Eakin 1999). In early 1898, the first scientific expedition from Costa Rica was to Isla del Coco, aboard the steamer Poás, and was organized by the IFGN (Pittier 1899). The expedition was led by Henri Pittier, the Director of the Institute (Table II.1). All the research was on land, but Anastacio Alfaro from the Museo Nacional de Costa Rica mentioned the presence of seabirds on the island (Alfaro 1899). The fourth major expedition that touched Isla del Coco was the Hopkins Stanford Galapagos Expedition of 1898–1899 (Heller 1903) (Table II.1); the only expedition from this phase partly funded by a philanthropist. This expedition was organized by the Zoology Department at Stanford University under the patronage of Timothy Hopkins, using a sealing schooner. The primary interest was in collecting vertebrates, but many groups of animals and plants were collected, including coastal marine organisms. On the way back to the United States they stopped at Isla del Coco on 29 June 1899 and stayed there 4 days. Many papers were published mainly on terrestrial vertebrates and plants, a few publications were on marine organisms (Rathbun 1902; Snodgrass & Heller 1905), and papers were published until the early 20th century (e.g., Dall 1908, 1920).In 1902, under the leadership of Henri Pittier, the government organized an expedition to Isla del Coco, aboard the steamer Turrialba. Paul Biolley participated as a naturalist from the Instituto Físico-Geográfico Nacional. He collected mollusks and listed 34 species, including

23 marine gastropods (Biolley 1907). He also collected an amphipod that was sent to Thomas R.R. Stebbing, and was subsequently described as a new species (Stebbing 1903). That was one of the several new species that Stebbing (1906, 1908) described from samples sent by Biolley from several coastal areas of Costa Rica. Once more, from 1904 to 1905 the US Fish Commission Steamer Albatross was used in the eastern Pacific. No information on this cruise has been found and only two papers have been located in which samples from Costa Rica are mentioned; one with species of medusae and the other with siphonophorans (Bigelow 1909, 1911). The last expedition at the beginning of the 20th century to visit Isla del Coco was the California Academy of Sciences Expedition to the Galapagos Islands. This expedition visited the island from 3 to 13 September 1905, and collected insects, birds, lizards, and freshwater animals. All the marine animals mentioned (not

collected) were large vertebrates: fishes, turtles, sharks, devilfish, and whales. Most of the marine animals that they collected were eaten (Slevin 1931). On 22 March 1920, the RV Alexander Agassiz, of the Scripps Institution of Oceanography, visited Costa Rica and dredged near the Islas Murciélago (northern Pacific of Costa Rica). Several mollusks were collected by Captain W.C. Crandall and E.L. Michael (Luke 1995) (Table II.1). I have not found any other reference to this cruise or seen any publication in which the specimens collected are mentioned. In summary, during this first phase of scientific exploration, from 1832 to 1920, at least 45 papers were published, which include information on specimens collected in Costa Rica. Of these papers about one third was based on collections by individuals and the rest associated with expeditions (Cortés in preparation).

57

Second Phase: 1924 to the 1990s Another intense phase of exploration occurred between 1924 and 1939 when many expeditions visited Costa Rica (details of all the expeditions are given in Table II.1); the larger ones were funded mainly by philanthropists. In 1924, there was a British expedition, one of only three European Expeditions to Costa Rica during this phase lead by Cyril Crossland aboard the St. George. Mollusks from Isla del Coco were reported by Tomlin (1927) and medusae, collected at two tow-netting stations south of the island by Kramp (1956). An important expedition during this phase was the Arcturus Oceanographic Expedition (Figs. II.3 and II.4), in 1925, organized by the New York Zoological Society and led by William Beebe. It undertook plankton tows south and north of Isla del Coco, and made collections on and around the island for 10 days in May 1925 (Beebe 1926). Tee-Van (1926) presents a detail account of the equipment used and the operations. At least eight papers were published that include information from Costa Rica (Cortés in preparation). The next expeditions were the cruises with the yachts Eagle and Ara in 1926 and 1928, commanded by William K. Vanderbilt. So many specimens were collected during these expeditions that W.K. Vanderbilt founded the Vanderbilt Marine Museum in Centerport, New York to house them. They collected at Isla del Coco in 1926 and around Puntarenas and Isla del Caño in 1928 (Boone 1930a, b, 1933).

Lee Boone reported and described species of many crustacean groups, coelenterates, echinoderms, and mollusks. In 1929, Governor Gifford Pinchot traveled to the South Seas, across the Caribbean, the Panama Canal, then to Isla del Coco and the Galápagos, before heading to the Marquesas, Tahiti, and Society islands. During this so-called Pinchot South Seas Expedition, A.K. Fisher of the United States Biological Survey, and Henry A. Pilsbry of the Academy of Natural Sciences of Philadelphia, collected fishes, including five species of marine fishes and one freshwater species from Isla del Coco (Fowler 1932). The second European expedition to visit Costa Rica during this phase was the Austrian Biological Expedition to Costa Rica in 1930. This brief expedition collected nothing on the Caribbean coast, but obtained eight marine crabs from Puntarenas and Golfo Dulce, on the Pacific coast (Pesta 1931). In 1932, the Templeton Crocker Expedition of the California Academy of Sciences set sail for the eastern Pacific (Table II.1). During this expedition the following sites in Costa Rica were visited: Puntarenas (spelled Punta Arenas in the Appendix) from 22 to 26 June and on 30 June, in transit from Puntarenas to Isla del Coco and at the island from 26 to 30 June; Bahía Brasilito (indicated as Braxilito Bay) on 1 and 2 July; Bahía Murciélago on 2 and 3 July; and Bahía de Santa Elena (designated as Port Parker) on 3 and 4 July (Crocker 1933). Many papers were published, from terrestrial fungi to birds; and at least nine contain information on marine organisms collected in Costa Rica (Cortés in preparation). A sample of three of the publications are: Hertlein (1935) on pectinidid bivalves, Setchell (1937) on algae of the genus Sargassum, and Bigelow (1940) on medusae.During 1937 and 1938, there was an expedition of the New York Zoological Society with the yacht Zaca to the eastern Pacific, under the


59

scientific leadership of William Beebe (Table II.1). It collected at Islas Murciélago, Santa Elena, Potrero Grande, Culebra, Brasilito, Sámara, Ballena, Uvita, and Pavones bays, off Cabo Blanco, around several islands in the Golfo de Nicoya, southeast of Punta Judas, south of the Osa Peninsula, at the entrance to Golfo Dulce, and within the gulf and in Golfito (Beebe 1938). At least 22 papers have been published in which specimens collected in Costa Rica during these expeditions were mentioned (Cortés in preparation). Two groups, mollusks, and crustaceans, were studied in great detail, and there is one paper on echinoderms. The Allan Hancock Foundation Velero III expeditions to the eastern Pacific that visited Costa Rica took place between 1932 and 1939 (Table II.1). In February 1932, Bahía Chatham at Isla del Coco was sampled; in February–March 1933: Chatham and Wafer bays at Isla del Coco, and Culebra and Cocos bays on the mainland; in February 1934: points around Bahía Culebra; in February 1935: Playa Blanca, Port Parker (now Bahía de Santa Elena) and Bahía Salinas; in January 1938: Nuez Island (now Isla Manuelita), Wafer and Chatham bays all at Isla del Coco; and finally in March 1939: Bahía de Santa Elena and Golfo Dulce (Fraser 1943). At least 58 papers have been published on the material collected (Cortés in preparation), covering algae (Taylor 1945) to echinoderms (Ziesenhenne 1942), including corals, mollusks, crustaceans, and fish parasites (Manter 1940). Specimens from these collections are still being analyzed and papers published (e.g., Barnard 1980; Castro 1996). One of the last expeditions of the 1930s was the Presidential Cruise (Franklin D. Roosevelt, US President, on board the USS Houston) from July to August 1938, under the scientific leadership of Waldo L. Schmitt of the Smithsonian Institution (Table II.1). It collected samples on 3 August 1938 from Isla del Coco (Schmitt 1939). At least five papers (Cortés in preparation), covering five different phyla, were published on species from Isla del Coco. Additionally, Schmitt (1940), in his review of stomatopods mentioned a species from Isla San Lucas sent to the US National Museum by Manuel Valerio in 1930. During the next 15 years, which included the Second World War, there was only the US Navy Galapagos Expedition (1941) that touched Isla del Coco. Waldo L. Schmitt collected some specimens (Smithsonian Institution Archives), but no reports on them have been published yet. The next expeditions (Table II.1) occurred in the 1950’s. Between 1952 and 1953 the Wooldrow G. Krieger Expedition to the eastern Pacific, collected fish in Galápagos and Isla del Coco. Later, Halstead & Schall (1955) published on the toxicity of venenous fish collected at Isla del Coco. In 1953 and 1954 the RV Xarifa, led by Hans Hass, the third European expedition, visited the eastern Pacific. Corals were collected from Isla del Coco by Georg Scheer in 1954 (Durham 1962). Apparently the RV Vema visited Isla del Coco on 30 November 1958 (Child 1992), but I have found no information about this expedition or any other publication in which it is mentioned. In 1959, the Stella Polaris visited the eastern Pacific for the Beaudette Foundation (Dawson & Beaudette 1959). Dawson (1960) published a list of the species of algae, including new species from Mexico and Central America, with a significant number of species from Costa Rica. In the decade between 1968 and 1978 there were five expeditions to the eastern Pacific and collections were done in Costa Rica. The Stanford Oceanographic RV

Te Vega expeditions #18 and #20 in 1968, cruise 76 of the RV T.G. Thompson in 1969, and two expeditions of the RV Agassiz (Scripps Institution of Oceanography), one in 1973 and another in 1978 (Table II.1). The Stanford Oceanographic Expedition 18, between April and June 1968, sampled intertidal fauna and flora from Paita, Perú to Bahía Magdalena, Baja California, México. In Costa Rica they collected in the area of Negritos and Cedros islands, Golfo de Nicoya (11–12 May) and Bahía Brasilito (13 May; Ball 1972). From this expedition three papers were published in which samples from Costa Rica were mentioned, two on hermit crabs (Ball 1972; Ball & Haig 1974) and one on barnacles (Zullo 1991). One of Zullo’s reports is from Isla del Coco, collected during Cruise 18 of the Te Vega; however, this is a mistake, since Ball (1972), in his station map of that cruise, did not indicate that Isla del Coco was visited. The Stanford Oceanographic Expedition 20 (September–December 1968) sampled two stations: one just off Isla del Coco (Z78: 5°34′ N 86°58′ W, 22 October 1968) and one northwest of Cocos (G-36: 7°29′ N 87°58′ W, 27 October 1968), where cephalopods were collected (Fields & Gauley 1972). During that expedition Isla del Coco was visited on 22 October, but weather conditions were not good. Trawls were done with no success due to clumps of corals, which snagged the net. John S. Pearse collected Diadema by diving (Stanford University Archives), but no publication has been found in which any sample collected was mentioned. The first scientific exploration of Golfo Dulce was in 1969 Cruise 35 aboard the RV T.G. Thompson. Richards et al. (1971) described the physicochemical characteristics of this tropical fjord, while NichollsDriscoll (1976) worked samples of benthic fauna. The Scripps Institution of Oceanography conducted expeditions in the eastern Pacific and did some collections in Costa Rica with the RV Agassiz in 1973 and with RV Alpha Helix in 1978. Wicksten (1979) reported a new record of a benthic bathyal shrimp off Punta Guiones during the 1973 cruise. All other records of specimens collected are in the catalogs of the Benthic Invertebrate Collections of the Scripps Institution of Oceanography (Luke 1977, 1995). The Instituto de Ciencias del Mar y Limnología of the Universidad Nacional Autónoma de México collected plankton samples at the Costa Rica Dome with their research vessel PUMA twice in 1979, and once in 1981 and 1982 (Table II.1). The collected material formed the basis for many theses (Cortés in preparation) and the following papers: Sánchez-Nava & Segura-Puertas (1987) on pelagic gastropods; Suárez-Morales & Gasca (1989) on epipelagic calanoid copepods; Segura-Puertas (1991) on medusae; Gasca & Suárez (1992) on siphonophores, and finally SeguraPuertas et al. (1992) on chaetognaths. Between 1983 and 1995, malacological collections were made at Isla del Coco by a group consisting of Kirstie L. Kayser, Michel Montoya, and Donald R. Shasky, aboard the Schooner Victoria af Carlstat (Montoya 2007). Many collection methods were used: hand-picking in the intertidal zone, snorkeling, SCUBA, tangle nets, and dredges. More than 50 papers were published, significantly increasing the number of mollusk species reported for the island, including a large number of new species (Cortés in preparation). A small sample of some of the papers is presented in Table II.2.

In 1986, the Harbor Branch Oceanographic Institution at Fort Pierce, Florida, used their submarine, the Johnson-Sea-Link I, to collect around the Galápagos Islands and Isla del Coco (Table II.1). Two papers were published, one on ahermatypic corals (Cairns 1991a) and another on stylasters (Cairns 1991b). In 1987, the fisheries RV F. Nansen visited the Golfo de Papagayo, and Bianchi (1991) reported collecting 14 invertebrates (two cephalopods, two stomatopods, and ten decapod crustaceans), but gave no details on the species. The Natural History Museum of Los Angeles County organized an expedition to Isla del Coco in 1988 aboard the Schooner Victoria af Carlstat. Two papers have information on organisms from the island collected during that expedition: the first on four species of stomatopod crustaceans, three of them are new reports for the island (Camp & Kuck 1990), and the second on brachyuran crabs (Zimmerman & Martin 1999). In 1987 aboard the RV Benjamin and again in 1990 on the RV Gyre, scientists from the Smithsonian Tropical Research Institute visited Isla del Coco (Table II.1), and later published several papers on the distribution of echinoids in the eastern Pacific (e.g., Lessios et al. 1996, 1998, 1999, 2003). Macintyre et al. (1992) as part of the 1990 RV Gyre expedition took coral cores to reconstruct the Holocene history of the islands’ coral reefs, at Isla del Caño and Isla del Coco. In 1994, during a geophysical expedition of the submersible Alvin operated by the Woods Hole Oceanographic Institution (Table II.1) collected several organisms that are deposited at the National Museum of Natural History, Smithsonian Institution in Washington, DC. No report has been published regarding these specimens. Again in 2005, specimens were collected using the Alvin (Table II.1), but this time they were donated to the Universidad de Costa Rica (J.A. Vargas, 2005, personal communication). Scientists from the Smithsonian Tropical Research Institution and other organizations collected fishes at Isla del Coco aboard the RV Urracá in 1997 (D.R. Robertson, 2007, personal communication) (Table II.1). In 2001, the SSV Robert Seamans visited Isla del Coco and plankton samples were collected (Table II.1), but no paper has been published based on those samples. All the major expeditions and the main collections have been made on the Pacific side of Costa Rica, with only four short expeditions to the Caribbean

(Table II.1). The first was the Austrian Biological Expedition in 1930, when a few freshwater crabs were collected (Pesta 1931). The second expedition was by the US Navy for a study of the zooplankton of the Caribbean Sea; they collected at one station off Limón in 1968 (Michel & Foyo 1976). The third expedition was the RV John Elliott Pillsbury Cruise P-7101 to Central America (20 January–5 February 1971) from the School of Marine and Atmospheric Science, University of Miami, with Gilbert L. Voss as Chief Scientist (Voss 1971). They visited 11 stations from off the Río Sixaola to offshore between Río Tortuguero and Río Colorado (26 and 27 January 1971). Trawls and plankton tows collected sponges, mollusks, crabs, crinoids, sea stars, holothurians, a few polychaetes, pennatulids, and nemerteans, and “typical surface plankton” (Voss 1971). Lastly, the RV Alpha Helix (Belém to Belize City Expedition) in 1977 generated one paper noting copepods collected (9 July) off the Port of Limon (Ferrari & Bowman 1980). Between the late 1950s and the 1990s individual foreign scientists continued to contribute to the knowledge of Costa Rican marine biodiversity both in the Caribbean and the Pacific. These scientists were not connected to any national institution. A few examples are: Elmer Yale Dawson who was invited by a Mr. Maurice A. Marchis to visit Golfo de Nicoya and Golfo Dulce in June 1957, where he collected 108 species of algae (Dawson 1957). Dawson again visited Costa Rica in 1962, while attending the second annual Advanced Seminar in Tropical Biology at the University of Costa Rica. He published on the marine algae of the Caribbean coast, and expanded the list of algae for Costa Rica to 196 species (Dawson 1962). Banta & Carson (1977) described 24 species of bryozoans, from Portete and Playas del Coco, collected in 1964. Houbrick (1968) collected 250 species of mollusks in 1966 at Portete and Barra del Colorado, Caribbean. Charles Birkeland and Tom M. Spight (Smithsonian Tropical Research Institute) collected ascidians (= tunicates) from Playas del Coco in February–March 1970. With that collection Tokioka (1971, 1972) described a new species and listed 14 ascidians (= tunicates) as present in Costa Rica. Dexter (1974) published on the macroinfauna of beaches from the Caribbean and Pacific of Costa Rica collected in 1971. Child (1979) reported on sea spiders collected in Golfo de Nicoya and Playas del Coco by C.E. Dawson and C.A. Child in 1972. David G. Robinson worked on fossil formations from the Caribbean, but also collected and identified 395 living mollusks from the Caribbean coast (Robinson & Montoya 1987). Finally, Jung (1989) through the Panama Paleontology Project of the Smithsonian Tropical Research Institute published on strombinids collected in Costa Rica.

Third Phase: Early 1970s to the Present From the early 1970s Costa Ricans, resident foreign scientists, and foreign scientists in association with local institutions have started to contribute significantly to the knowledge of the country’s marine biodiversity. The return of Manuel M. Murillo and Carlos Villalobos to Costa Rica was important for the motivation and


63

recruitment of young students into the marine sciences. Manuel Murillo (Fig. II.5) was also a key figure in the design and implementation of the research system at the Universidad de Costa Rica (UCR), through the creation of research centers and institutes and the Graduate School. In 1979, the Marine Sciences and Limnology Research Center (Centro de Investigación en Ciencias del Mar y Limnología; CIMAR, Fig. II.6) at UCR was founded. A significant contribution to the knowledge of Costa Rica’s marine biodiversity during this phase has been made by William A. Bussing, a resident foreign scientist, who started working on the Central American fish fauna in the 1970s (Bussing 1980). He has continued describing marine and freshwater species to the present (Bussing & Lavenberg 2003), and now has at least 40 papers on fishes, including many new species (Tables II.3 and II.4). The first expeditions in which Costa Rican or foreign resident scientists participated were conducted in 1972 and 1973. The first was the RV Searcher Central American Expedition in 1972, and the second was the Velero IV Costa Rica Expedition in 1973. The Janss Foundation vessel, RV Searcher, visited Costa Rica in 1972 and the Chief Scientist was William A. Bussing (UCR) (Table II.1). Between 29 March and 8 April, the expedition visited Isla del Coco, and Bakus (1975) published the first report on the underwater zonation of its coral reefs. Manning & Reaka (1979) and Reaka & Manning (1980) published on stomatopod crustaceans from Bahía Herradura, Quepos, Isla del Caño, Puerto Jiménez, and Golfo Dulce, and Reid & Kaiser (2001) described a species of gastropod dredged from Bahía Herradura.

From 5 May to 1 July 1973, the RV Velero IV cruises 1244–1247 took place with Richard Pieper as cruise leader (J. Crampon and K. Fauchald, 2005, personal communication) (Table II.1), and they worked primarily off the Pacific coast of Costa Rica; some sampling was also done off Panama and Isla del Coco; M.M. Murillo and W.A. Bussing from the Universidad de Costa Rica participated in this cruise. The sampling devices included a box corer, beam trawl, hydrocast, Isaacs Kid Mid Water Trawl (IKMWT), acoustic trawl, Campbell benthic grab, biological dredge, and plankton tow-net. Sampling depths were from 18 to 3,750 m; the majority of the sampled were collected between 1,000 and 2,000 m with only a few from shallow waters. In Costa Rica, the following sites were sampled: north of Cabo Velas, Punta Guiones, Punta Coyote, Cabo Blanco, Negritos Adentro and Isla Aves/Golfo de Nicoya, Isla Herradura, Isla del Caño, Cabo Matapalo, Punta Arenitas/Golfo Dulce, Isla Burica, Isla del Coco, and off Isla Manuelita (J. Crampon, 2005, personal communication). The creation of the CIMAR at the UCR in 1979 is a turning point in marine research in Costa Rica. The first large-scale project was with the University of Delaware, and a research vessel, the RV Skimmer, was operated in the Golfo de Nicoya from 1979 to 1981 (Vargas 1995) (Figs. II.7 and II.8). Based on the research carried out using that vessel, more than 100 papers have been published by CIMAR or collaborating scientists on biodiversity, processes, ecology, physical, and chemical characteristics, pollution, and ecosystems of the Golfo de Nicoya (www.cimar.ucr.ac.cr).

Between 1993 and 1994, an expedition was organized between CIMAR and the Center for Tropical Marine Ecology (ZMT), University of Bremen, Germany (Vargas & Wolff 1996). The RV Victor Hensen (Fig. II.9) collected samples along the Pacific coast, mainly from Golfo Dulce, Bahía de Coronado, and Golfo de Nicoya. Many papers were published from that expedition and some were directly related to marine biodiversity (e.g., Bussing & López 1996; Morales-Ramírez 1996; Vargas et al. 1996; León-Morales & Vargas 1998).

In late 2006 and again in early 2007, Isla del Coco was visited by scientist from CIMAR aboard the MV Proteus (Fig. II.10, Table II.1); the objective of the first expedition was the evaluation and establishment of monitoring sites, but organisms were also collected. The second expedition’s objective was the collection of organisms from the intertidal down to 40 m depth. New species are being discovered of even conspicuous groups such as octocorals (probably one new species collected in January 2007; Breedy & Cortés 2008); and several new records of species were reported (e.g., echinoderms) (Alvarado in press). Most of the papers published on marine biodiversity since the 1980s have been done through three national institutions: Universidad de Costa Rica (UCR), Universidad Nacional (UNA), and Instituto Nacional de Biodiversidad (INBio). The taxonomic groups studied are mentioned below, but only publications related to biodiversity are mentioned. There is an extensive bibliography on research on fishes, marine invertebrates, and ecology (Cortés in preparation). The UCR has contributed to the knowledge of many groups that has amplified our knowledge of marine biodiversity; over 100 papers have been published on the marine biodiversity of Costa Rica. The largest contribution has been on fish by W.A. Bussing and M.I. López (Tables II.3 and II.4). A list of papers published by CIMAR scientists or their associates is presented in Tables 3 and 4, in which a total of 67 new species were described. Other contributions by UCR scientists from the Museo de Zoología have contributed to the knowledge of marine biodiversity of Costa Rica (e.g., Camacho-García & Gosliner 2004, 2006; Camacho-García et al. 2005).

Researchers of the UNA have contributed to the study of marine biodiversity mainly on mollusks through the contributions of Rafael A. Cruz (e.g., Cruz 1985, 1996; Cruz & Jiménez 1994). One paper has been published on the taxonomy of sponges (Loaiza 1991). The INBio has published on mollusks (The Malacology Department was closed in September 2004 and the collections transferred to the Museo de Zoología, Escuela de Biología, UCR). In collaboration with Cuban and Spanish malacologists about 20 papers were published, but just a few are mentioned here. Papers on the mollusks of the Caribbean coast of Costa Rica include the description of new species published by Espinosa & Ortea (1999, 2000, 2001) and Ortea et al. (2001). Another series of papers is on nudibranchs from the Caribbean (Ortea et al. 1999; Ortea 2001) and from the Pacific (Camacho-García & Ortea 2000; CamachoGarcía & Valdés 2003).

Conclusions Three phases are recognized as productive in the generation of marine biodiversity information for Costa Rica: the late 19th century, between 1930 and 1940, and after 1980. The knowledge of marine biodiversity increased significantly during those phases, but there is a difference between research conducted by foreign scientists with no connection to local institutions, and research done by local and resident scientists or by foreign scientists in true collaboration with local institutions. In the first case, a large amount of new knowledge was generated, but little of that came back to the country, and no collections were left in the country or returned afterward. This was normal practice at the time, but also, it could have been due to the lack of national scientific institutions interested in marine organisms or to the absence of local scientists working on marine biodiversity. Until the early 1970s no Costa Rican was trained in the study of marine organisms. In the second case, Costa Rica scientists had been trained and collections were deposited in Costa Rica. In the early 1970s, the Universidad de Costa Rica organized its research activities. Professors went abroad for advanced degrees, the Museo de Zoología at the Escuela de Biología was set up (1966), and research centers were created. During that phase the first research on marine organisms started. In 1976, the new building of the Museo de Zoología was completed, creating an area and environment conducive for research. In 1979, the CIMAR was founded, significantly advancing marine sciences in Costa Rica, including biodiversity studies. At present, most foreign scientists work in collaboration with Costa Rican scientists, resulting in a direct transfer of information to Costa Rica, training of students and researchers, and enlargement of research collections in Costa Rica. It is important to have a strong local scientific community and institutions for the reception of information and collections produced by foreign scientists, for the generation of new knowledge, and for the use of that experience and information in teaching, advancing research, and for the management and rational use of the marine resources of the country.
