Diversidad funcional de peces herbívoros arrecifales en el Pacífico Tropical Oriental
(2023)Los arrecifes de coral brindan servicios ecosistémicos insustituibles para el desarrollo humano. Sin embargo, debido al aumento de la presión antrópica, presentan una gran pérdida de especies y un deterioro de las funciones ... -
Diversidad genética y variación en la viabilidad de plantas nativas cultivadas en sistemas agrícolas tradicionales.
(2011-06-29)El objetivo de este proyecto es caracterizar la diversidad genética y las diferencias en viabilidad en variedades tradicionales de plantas cultivadas nativas de la región centroamericana. -
Diversidad y estructura genética de la danta Centroamericana (Tapirus Bairdii) en el noroeste de la cordillera de Talamanca y en el corredor biológico Tenorio-Miravalles, Costa Rica
(2023)Tapirus bairdii is the largest terrestrial herbivore living in Mesoamerica, distributed from southern Mexico to northwestern Colombia. Tapirs play relevant ecological roles as seed dispersers and nutrient cycling redistributors ... -
Diversidad y vulnerabilidad de la flora orquideológica de un bosque montano nuboso del Valle Central de Costa Rica
(2019)Los Cerros de La Carpintera son una formación montañosa en el Valle Central de Costa Rica que alberga remanentes de bosque nuboso en sus partes altas y están rodeados por áreas urbanas y agrícolas. Con el interés de promover ... -
Diversity and composition of tropical forest plant communities in the Golfo Dulce region
(2019)The Golfo Dulce region located in southwestern Costa Rica represents one of the remnant global biodiversity hotspots containing the largest Pacific lowland tropical forest in Central America. Recent biogeographical analyses ... -
Diversity and Conservation of Cave-Dwelling Bats in the Brunca Region of Costa Rica
(2018-06-02)The Brunca region in Costa Rica contains the largest number of caves in the country, yet the diversity and distribution of bat species within those caves is currently unknown. Without this information, it is not possible ... -
Diversity and hidden host specificity of chytrids infecting colonial volvocacean algae
(2018-05)Chytrids are zoosporic fungi that play an important, but yet understudied, ecological role in aquatic ecosystems. Many chytrid species have been morphologically described as parasites on phytoplankton. However, the majority ... -
Diversity of Bacillus thuringiensis strains isolated from coffee plantations infested with the coffee berry borer Hypothenemus hampei
(Universidad de Costa Rica, 2004)The coffee berry borer Hypothenemus hampei Ferrari (Coleoptera: Scolytidae) was first reported infecting Costa Rican coffee plantations in the year 2000. Due to the impact that this plague has in the economy of the country, ... -
Diversity of deep-sea echinoderms from Costa Rica
(2022-07-31)Echinoderms are a highly diverse group and one of the most conspicuous in the deep sea, playing ecological key roles. We present a review about the history of expeditions and studies on deep-sea echinoderms in Costa Rica, ... -
Diversity patterns, ecological associations and future of research on Costa Rican myxomycetes
(2018-06-05)The most active research period on myxomycetes in Costa Rica has taken place in the last three decades. During this time, most of the collections have been carried out and most of the scientific articles have been produced. ... -
DNA barcoding the floras of biodiversity hotspots
(2008-02-26)DNA barcoding is a technique in which species identification is performed by using DNA sequences from a small fragment of the genome, with the aim of contributing to a wide range of ecological and conservation ... -
DNA-assisted identification of Caulerpa (Caulerpaceae, Chlorophyta) reduces species richness estimates for the Eastern Tropical Pacific
(2016)Taxonomy and species richness estimates for the genus Caulerpa have proven challenging due to the difficulty of assessing morphological species limits. In the present study we evaluate the taxonomy of the genus and assess ... -
Do different methods yield equivalent estimations of brain size in birds?
(2020-08-31)The ratio of brain size to body size (relative brain size) is often used as a measure of relative investment in the brain in ecological and evolutionary studies on a wide range of animal groups. In birds, a variety of ... -
Documentation of floral secretory glands in Pleurothallidinae (Orchidaceae) using Scanning Electron Microscopy (SEM)
(2016-11-20)A clear, step by step description of the treatment of orchid flowers, subtribe Pleurothallidinae, with Critical Point Drying for SEM is presented. It shows that a simple, short fixation and dehydration method prior to ... -
Does a polyphagous caterpillar have the same gut microbiota when feeding on different species of food plants?
(Revista de Biología Tropical 50(2): 547-560, 2002, 2002)We used classical culture techniques to explore gut bacteria and changes associated with dietary change in the highly polyphagous, tropical caterpillar Automeris zugana(Saturniidae). Fifty-five third instar wild-caught ... -
Does habitat loss affect tropical myxomycetes?
(2014-10-29)The effect of habitat loss on the dynamics of myxomycete assemblages has been poorly studied thus far. For this reason, a premontane moist forest surrounded by human-created pastures on the Caribbean slope of Costa Rica ... -
Does the distance to forests or buildings influence great kiskadee (Pitangus sulphuratus) nesting site selection?
(2021)The expansion of human settlements has produced significant changes in natural ecosystems by fragmenting and reducing their area. Those changes influence the availability of natural and artificial sites used to build nests ...
