Brachiopods, sipunculans, enteropneusts and metals from two estuarine tidal flats, Pacific, Costa Rica
(2016-09)Reports on the abundances and on metal concentrations in intertidal estuarine invertebrates from the Eastern Tropical Pacific are rare. Thus, the objectives of this report are to make accessible data on the abundances ... -
Bryozoans
(I.S. Wehrtmann, J. Cortés (eds.) Marine Biodiversity of Costa Rica, Central America. Springer., 2009)Sixty-one species of bryozoans have been reported in the literature from Costa Rica and are distributed as follows: Caribbean: 13 species in 11 genera, 10 families, 1 order, and 1 class; Pacific: 49 species in 41 genera, ... -
By-catch associated with fisheries of Heterocarpus vicarius (Costa Rica) and Heterocarpus reedi (Chile) (Decapoda: Pandalidae): a six-year study (2004-2009)
(Journal of Crustacean Biology, 33(2), 198-209. 2013, 2013)Growing concern about the quantity and diversity of by-catch species caught in the bottom trawling nets of crustacean fisheries led us to compare the quantity of by-catch recorded in Chilean and Costa Rican deep-water ... -
Características poblacionales del cambute, Strombus galeatus (Gastropoda: Strombidae) en el Parque Marino Ballena, Pacífico, Costa Rica (1999-2003)
(2008-12)Marine parks and reserves are important for biodiversity conservation and as sustainable places for recovery of fishery resources, especially for those species of economic importance such as the Pacific conch Strombus ... -
Caulerpa sertularioides, a green alga spreading aggressively over coral reef communities in Culebra Bay, North Pacific of Costa Rica
(2005)Caulerpa sertularioides, is a widespread chlorophyte, that can be confused with C. taxifolia, a highly invasive algae. C. sertularioides has erect, feather-like, occasionally branched fronds; its branchlets are opposite, ... -
Change in the composition of fauna associated with Pocillopora spp. (Scleractinia, Pocilloporidae) following transplantation
(2023-04-30)Introduction: Associated fauna comprises most of the diversity of a coral reef and performs ecological functions essential to the reef’s survival. Since Pocillopora corals harbor an important associated fauna, reef ... -
Changes in abundance and composition of a Caribbean coral reef zooplankton community after 25 years
(2016)Coral reef zooplankton represents a key community in coral ecosystems, as they are involved in trophic and biogeochemical dynamics, and recruitment processes. Zooplankton abundance, composition and biomass were surveyed ... -
Checklist of the Pacific marine macroalgae of Central America
(2011)Our present knowledge of marine macroalgal diversity for the Central American Pacific coast is limited by the short history of investigations (ca. 100 years) and few algal spe- cialists through a large geographical area. ... -
Chlorophyta de la Costa Pacífica de Costa Rica
(2008-12)Recent collections at the Pacific coast of Costa Rica have increased the number of reported marine green algae. In this paper we present an updated list of the marine green algae of this coast, which is based on reports ... -
Chloroplast genomes as a tool to resolve red algal phylogenies: a case study in the Nemaliales
(2016)Obtaining strongly supported phylogenies that permit confident taxonomic and evolutionary interpretations has been a challenge in algal biology. High-throughput sequencing has improved the capacity to generate data and ... -
Las ciencias del mar en la Revista de Biología Tropical en su 50 aniversario
(Rev. Biol. Trop. 50(3/4): 903-907, 2002, 2002)El primer artículo sobre cualquier tema marino fue publicado en 1963 y desde entonces ha venido aumentando el número de publicaciones marinas hasta llegar a 637. Este número representa el 27% de todos los artículos ... -
