Bosques de coral negro del Área de Conservación Guanacaste, Costa Rica: especies y distribución
(2021-09-06)Introduction: Little is known about the antipatharians in Costa Rica, only three species are known from the Pacific and the occurrence of coral forests was previously reported only for Isla del Coco. Black ... -
Brachionium kirbyi, a new species honoring the founder of the “Bosque de Paz” Orchid Project in Costa Rica
(2015)A new species of Brachionidium from Costa Rica is described and illustrated. Brachionidium kirbyi is most similar to Brachionidium dressleri Luer. It can be recognized by the erect plants, up to 14 cm tall, often branching, ... -
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 ... -
Brain structure–function associations in multi-generational families genetically enriched for bipolar disorder
(2015-05)Recent theories regarding the pathophysiology of bipolar disorder suggest contributions of both neurodevelopmental and neurodegenerative processes. While structural neuroimaging studies indicate disease-associated ... -
Brief research history and status of myxomycete conservation in the Neotropics
(2012-11-08)As it is the case of most disciplines, biological groups and regions in the world; the historical path of research on myxomycetes in the Neotropical region has been written on the basis of a series of milestones, iconic ... -
Bryophyte and lichen biomass and nitrogen fixation in a high elevation cloud forest in Cerro de La Muerte, Costa Rica
(2021-01)Cloud forests have been found to lose more nitrogen in stream discharge than they gain from atmospheric deposition. They also support a large diversity and biomass of tree epiphytes, predominately composed of cryptogams. ... -
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, ... -
Burkholderia from fungus gardens of fungus-growing ants produce antifungals that inhibit the specialized parasite Escovopsis.
(2021-06)Within animal-associated microbiomes, the functional roles of specific microbial taxa are often uncharacterized. Here, we use the fungus-growing ant system, a model for microbial symbiosis, to determine the potential ... -
Búsqueda y caracterización de proteínas biopesticidas novedosas a partir de cepas de Bacillus thuringiensis
(1999)En la actualidad se desarrollan y se cultivan comercialmente plantas transgénicas que expresan endotoxinas de Bacillus thuringiensis (Bt) como biopesticida para el control específico de insectos. Sin embargo, se teme que ... -
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 ... -
C1 compounds shape the microbial community of an abandoned century-old oil exploration well
(2020)The search for microorganisms that degrade hydrocarbons is highly relevant because it enables the bioremediation of these substances cheaply and without dangerous by-products. In this work, we studied the microbial communities ... -
Calling for more accurate information in aquarium trade: analysis of live-fish import permits in Costa Rica
(2017)Ornamental fish trade is a growing business around the world, but also a major pathway for the introduction of potentially invasive species. Trade patterns and policies have been evaluated in high-income countries while ... -
El camarón de agua dulce Macrobrachium cacinus (decapada, Palaemonida) y su potencial para la acuacultura en Costa Rica.
(2011-11-22)El objetivo del estudio es conocer aspectos básicos acerca el ciclo de vida de macrobrachium carcinus, un langostino que por su gran tamaño tiene potencial para la comercialización en la región. -
Cambios en el comportamiento territorial y vocalizaciones de la avifauna a lo largo del gradiente urbano y de ruido antropogénico
(2023)La urbanización a impulsado diferentes cambios drásticos en los hábitats naturales por el aumento de las áreas urbanas, generando gradientes urbanos y gradientes de ruido antropogénico. Como consecuencia de los cambios ... -
Can seedlings’ physiological information improve vegetation distribution predictions at local scales?
(2020-04-17)Physiological information has been suc- cessfully included in marine Species Distribution Models (SDM) before, but few have considered a previous development stage that could have affected the present-day distribution ... -
Can the location of the isolation laboratory affect the generation of myxomycete data using moist chambers? An experiment in the Neotropics
(2021-03-11)The moist chamber technique, as it is used in myxomycete research, is an extremely useful method to optimize project resources. However, as it occurs with any laboratory-based protocol, the usefulness of this technique ... -
Canines as a measuring tool for leaf tent construction in Dermanura watsoni
(2013)Many animals are capable of constructing structures to modify the environment for their own benefit. The design of these structures requires animals to perceive dimensions. However, how animals take measurements to achieve ... -
Cannibalism by large tadpoles of Rhinophrynus dorsalis (Anura: Rhinophrynidae)
