Fungal Endophytes and Their Bioactive Compounds in Tropical Forests of Costa Rica
(2021-04-15)We present a glimpse of the diversity of endophytic fungi in the tropical forests of Costa Rica and some examples of bioactive compounds obtained from them. We include the characterization of isolates carried out mainly ... -
Lankester-Garten, der Botanische Garten in Cartago, Costa Rica
(2002)The Lankester Botanical Garden of the University of Costa Rica was founded in 1973, it was named in honor of the English natural scientist and previous owner Charles H. Lankester (1879-1969). This garden is internationally ... -
Trichopilia x ramonensis - Darstellung einer Naturhybride aus Costa Rica
(2003)The natural hybrid Trichopilia x ramonensis (T. marginata x T. suavis) from the San Ramón region of Costa Rica is here presented and illustrated. Its name was validated in 2002, many years after its first mention in the ... -
Aportes científicos de un botánico universal: Luis Diego Gómez Pignataro (1944-2009)
(2010)Se analizan detalladamente las múltiples contribuciones científicas de Luis Diego Gómez a la botánica y la historia natural de Costa Rica y otros países neotropicales. -
A ClC Chloride Channel Homolog and Ornithine-Containing Membrane Lipids of Rhizobium tropici CIAT899 Are Involved in Symbiotic Efficiency and Acid Tolerance
(2005)Rhizobium tropici CIAT899 is highly tolerant to several environmental stresses and is a good competitor for nodule occupancy of common bean plants in acid soils. Random transposon mutagenesis was performed to identify novel ... -
In memoriam – Dora Emilia Mora de Retana (24.08.1940 – 12.07.2001)
(2001)Se resumen aspectos sobresalientes de la vida académica de la orquideóloga costarricense Dora Emilia Mora y se mencionan algunas de sus principales contribuciones en taxonomía y conservación de las orquídeas. -
Multilocus Sequence Analysis for Assessment of the Biogeography and Evolutionary Genetics of Four Bradyrhizobium Species That Nodulate Soybeans on the Asiatic Continent
(2008)A highly supported maximum-likelihood species phylogeny for the genus Bradyrhizobium was inferred from a supermatrix obtained from the concatenation of partial atpD, recA, glnII, and rpoB sequences corresponding to 33 ... -
Phylogenetic Relationships of Rhizobia Based on Citrate Synthase Gene Sequences
(2004)Partial nucleotide sequences of the citrate synthase (gltA) gene from different rhizobia genera were determined. Tree topologies based on this housekeeping gene were similar to that obtained using 16S rRNA sequences. However ... -
DESARROLLO DE CLONES GENÓMICOS INFECCIOSOS DE BEGOMOVIRUS QUE INFECTAN TOMATE Y CHILE EN LA REGIÓN CENTRAL OCCIDENTAL DE COSTA RICA E IMPLEMENTACIÓN DE UNA METODOLOGÍA BIOBALÍSTICA PARA LA INOCULACIÓN Y EVALUACIÓN DE INFECCIONES BAJO CONDICIONES CONTROLADAS
(2020-12-11)El impacto socioeconómico causado por los begomovirus en regiones tropicales y subtropicales, ha puesto a estos patógenos bajo el escrutinio de múltiples investigaciones a nivel mundial, que tienen como objetivo final ... -
Integrating chytrid fungal parasites into plankton ecology: research gaps and needs
(2017-06-15)Chytridiomycota, often referred to as chytrids, can be virulent parasites with the potential to inflict mass mortalities on hosts, causing e.g. changes in phytoplankton size distributions and succession, and the delay or ... -
Fungal Communities in Sediments Along a Depth Gradient in the Eastern Tropical Pacific
(2020-11-06)Deep waters represent the largest biome on Earth and the largest ecosystem of Costa Rica. Fungi play a fundamental role in global biogeochemical cycling in marine sediments, yet, they remain little explored. We studied ... -
FungalTraits: a user-friendly traits database of fungi and fungus-like stramenopiles
(2021-01-19)The cryptic lifestyle of most fungi necessitates molecular identification of the guild in environmental studies. Over the past decades, rapid development and affordability of molecular tools have tremendously improved ... -
Variation of bacterial communities along the vertical gradient in Lake Issyk Kul, Kyrgyzstan
(2021-02-04)We explored the diversity and community composition of bacteria along a vertical gradient in Lake Issyk Kul, Kyrgyzstan, one of the world's largest and deepest brackish lakes. We identified 4904 bacterial amplicon sequence ... -
Taxonomic Keys and Plates from The Myxomycetes
(2021-04-01)In 1969, George W. Martin and Constantine J. Alexopoulos published a remarkable work on myxomycetes. Their monograph on this group of organisms became one of the references to the taxonomy and geographical distribution of ... -
Energy flow structure and role of keystone groups in shallow water environments in Isla del Coco, Costa Rica, Eastern Tropical Pacific
(2019)Isla del Coco (Costa Rica) forms part of the five oceanic islands of the Eastern Tropical Pacific and is well known for its high biodiversity and great endemism. While several marine biological and oceanographical surveys ... -
New reports of echinoderms on the Caribbean continental slope of central America
(2019)The Caribbean is considered a unique biogeographic region that represents an important hotspot of marine diversity in the Atlantic Ocean. The Caribbean Continental Slope of Central America (CCCA) is a largely unexplored ... -
Cuando la conservación no puede seguir el ritmo del desarrollo: Estado de salud de los ecosistemas coralinos del Pacífico Norte de Costa Rica
(2018)When conservation can keep up with development´s pace: Health status of coral ecosystems in the North Pacific of Costa Rica. Coral reefs are diverse and productive ecosystems, despite this, they are being threatened by ... -
Determinants of reef fish assemblages in tropical Oceanic islands
(2019)Diversity patterns are determined by biogeographic, energetic, and anthropogenic factors, yet few studies have combined them into a large‐scale framework in order to decouple and compare their relative effects on fish ... -
Benefits of protection on reef fish assemblages in a human impacted region in Costa Rica
(2019)In recent years, there has been a health decrease in marine ecosystems. Due to this accelerated degradation, there is a more pressing need to investigate the effectiveness of MPAs in these degraded zones. In this work, we ... -
Coordinated hunting behaviors of mixed-species groups of piscivores and associated species at Isla del Coco National Park (Eastern Tropical Pacific)
(2019)Studies of mixed-species groups of animals can reveal emergent complexities of collective behaviors. In this study we collected data on mixed-species hunting groups composed primarily of piscivorous fishes (species ...
