“…Quantifying such global variation in biodiversity is an important goal of biology and is vital to channeling conservation efforts effectively (Wilson 1999). However, because inventorying biodiversity, especially marine biodiversity, is costly, difficult, and time consuming (Vargas & Cortés 2006, Solan et al 2009, there is great value in simple metrics that can reliably indicate a given region's biodiversity and that can be efficiently gathered (Wilson 1999).…”

Cuantificar la variación de la biodiversidad es un objetivo importantede la biología. Sin embargo, debido a que tales inventarios, en especialpara la biodiversidad marina, son costosos, difíciles y consumenmucho tiempo, hay un gran valor en indicadores simples que permitandeterminar la biodiversidad de una región determinada de maneraeficiente. Hicimos un inventario de las conchas usadas como casasmóviles terrestres por los cangrejos ermitaños (Coenobita compressus)en la Península de Osa, Costa Rica, un “punto álgido” de biodiversidad.Se registraron 41 especies, el mayor número registrado en cualquierpoblación de cangrejos ermitaños. Proponemos que la “diversidad delmercado de vivienda” en los cangrejos ermitaños puede proporcionarun índice de biodiversidad ecosistémica conveniente, lo que podríafacilitar las comparaciones entre sitios.ABSTRACTQuantifying variation in biodiversity is an important goal of biology.However, because inventorying biodiversity, especially marinebiodiversity, is costly, difficult, and time consuming, there is great valuein simple metrics that can reliably indicate a given region’s biodiversityand that can be efficiently gathered. We inventoried shells used asportable houses by terrestrial hermit crabs (Coenobita compressus) inOsa Peninsula, Costa Rica, a biodiversity hotspot. Forty-one species wererecorded, the largest number registered for any hermit crab population.We propose that housing market diversity in hermit crabs might providea convenient biodiversity index of ecosystems, potentially facilitatingcomparisons across different sites.

Hermit crabs associated to the shrimp bottom-trawl fishery along the Pacific coast of Costa Rica, Central America

et al. 2020

Studies of the bycatch associated to the shrimp trawling fishery in the Pacific coast of Costa Rica do not assess small organisms (< 10 cm TL) and non-dominant species (< 0.1% of total catch). There is a void in assessing the maintenance of the ecology and ecosystem on which the fishery depends. Furthermore, the Constitutional Court of Costa Rica prohibited the renewal of existing and the issuing of new shrimp bottom-trawl licenses, indicating the necessity of more scientific information on the impacts of this fishery. We present the results of a 23-month study of the shrimp bottom-trawl fishery performed between 50 and 350 m deep in the Pacific coast of Costa Rica. A total of 109 hermit crabs were collected (six species and two families). Paguristes cf. holmesi was the most common species. Zone II presented the highest species richness and abundance. Most specimens (81.8 %) were caught in shallower waters (50-149 m). More than 45% of the trawls presented hermit crabs. It is imperative to further assess the trawling effects on non-commercial benthic fauna and changes on predator-prey relationships before issuing new shrimp licenses

Marine biodiversity baseline for Área de Conservación Guanacaste, Costa Rica: published records

The diversity of tropical marine organisms has not been studied as intensively as the terrestrial biota worldwide. Additionally, marine biodiversity research in the tropics lags behind other regions. The 43,000 ha Sector Marino of Área de Conservación Guanacaste ( ACG , Marine Sector of Guanacaste Conservation Area), on the North Pacific coast of Costa Rica is no exception. For more than four decades, the terrestrial flora and fauna has been studied continuously. The ACG marine biodiversity was studied in the 1930’s by expeditions that passed through the area, but not much until the 1990’s, except for the marine turtles. In the mid 1990’s the Center for Research in Marine Science and Limnology ( CIMAR ) of the Universidad de Costa Rica ( UCR ) initiated the exploration of the marine environments and organisms of ACG . In 2015, ACG , in collaboration with CIMAR , started the BioMar project whose goal is to inventory the species of the marine sector of ACG (BioMar ACG project). As a baseline, here I have compiled the published records of marine ACG species, and found that 594 marine species have been reported, representing 15.5% of the known species of the Pacific coast of Costa Rica. The most diverse groups were the crustaceans, mollusks and cnidarians comprising 71.7% of the ACG species. Some taxa, such as mangroves and fish parasites are well represented in ACG when compared to the rest of the Costa Rican coast but others appear to be greatly underrepresented, for example, red algae, polychaetes, copepods, equinoderms, and marine fishes and birds, which could be due to sampling bias. Thirty species have been originally described with specimens from ACG , and 89 species are not known from other localities on the Pacific coast of Costa Rica except ACG . Most of the sampling has been concentrated in a few localities in Sector Marino, Playa Blanca and Islas Murciélago, and in the nearby waters of Bahía Santa Elena. In an effort to fill this gap, CIMAR is collaborating with ACG and a private foundation to start an inventory of the marine organisms of the conservation area. The project will be assisted by two marine parataxonomists, and all samples will be catalogued, photographed, bar coded and voucher specimens deposited at the Museo de Zoología, UCR . All the information will be available through Internet. It is anticipated that the BioMar project will fill many of the knowledge gaps and significantly more marine species will be encountered. This project could become a viable model for marine biodiversity inventories in other Costa Rican Conservation Areas (Áreas de Conservación) and in other countries.
