Early diverging lineages within Cryptomycota and Chytridiomycota dominate the fungal communities in ice-covered lakes of the McMurdo Dry Valleys, Antarctica
(2017-11)Antarctic ice-covered lakes are exceptional sites for studying the ecology of aquatic fungi under conditions of minimal human disturbance. In this study, we explored the diversity and community composition of fungi in five ... -
Eastern Pacific
(2017)In the Eastern Pacific (EP) the only region where rhodolith beds have been well studied in terms of taxonomy, ecology, distribution and conservation status is the Gulf of California. Outside this region the knowledge of ... -
Eastern Pacific coastal dynamics and the Intra-Americas summer low level jet
(2005)It is generally agreed that the circulation of the Eastern Pacific off México and Central America is forced in the summer by the large-scale circulation, namely the North Equatorial Countercurrent, and in the winter by ... -
Eastern Pacific Coral Reef Provinces, Coral Community Structure and Composition: An Overview
(2017)Advances in our knowledge of eastern tropical Pacific (ETP) coral reef biogeography and ecology during the past two decades are briefly reviewed. Fifteen ETP subregions are recognized, including mainland and island localities ... -
Eavesdropping avoidance and sound propagation: the acoustic structure of soft song
(2017-12)Many species use low-amplitude (soft) song during close range interactions with conspecifics, such as in aggressive encounters or courtship displays. It has been suggested that soft song is adapted to limit eavesdropping ... -
Echinoderm diversity of a tropical estuary in the largest river basin of the Costa Rican Pacific, Eastern Tropical Pacific
(2017)Echinoderms within the Eastern Tropical Pacific have mainly been studied in association with coral reefs. Investigations on echinoderms associated with soft-bottoms and estuaries are still scarce. The present study reports ... -
Echinosepala
(2020)Subtribe Pleurothallidinae is the largest and one of the most recently and intensely diversified groups in the Orchidaceae family. Estimates suggest that with a whopping 5500 species recognized today, pleurothallids represent ... -
El Eclipse total de Sol del 11 de Julio de 1991: Aspectos Generales.
(San José, CR: Editorial de la Universidad de Costa Rica, 1992)El 11 de junio de 1991 ocurrió un eclipse total de sol, el cual se pudo observar en casi todo el territorio de Costa Rica. El presente artículo explica en que consistió el fenómeno y describe las características principales ... -
Ecological and Public Health Effects of Microplastics Pollution
(2022-01)Humans and ecosystems are constantly exposed to microplastics (MP). The magnitude of contamination, their ubiquity, and high persistence over time raise serious concerns about their effects on ecosystems, wildlife, and ... -
Ecological aspects of myxomycete assemblages in two Brazilian Cerrado landscapes
(2021)We investigated the ecological aspects of the myxobiota associated with both the mesophilic and gallery forests from a fragment of the Cerrado biome located in the municipality of Anápolis, Goiás, Brazil. Myxomycete assemblages ... -
Ecological assessments of the coral reef communities in the Eastern Caribbean and the effects of herbivory in influencing coral juvenile density and algal cover
(2017)Caribbean reefs have been unevenly surveyed, with many areas lacking baseline data. In this study, the current status of Orbicella reefs, a structurally complex forereef habitat, was quantified in an understudied region, ... -
Ecological Correlates of Range Size in the Tent-Making Bat Artibeus watsoni
(2007-04)We examined variation in foraging- and roosting-range size in the tent-making bat Artibeus watsoni. We radiotracked 42 individuals at 2 sites in the Golfito Wildlife Refuge and 6 sites at Corcovado National Park, southwestern ... -
Ecological Correlates of Roost Fidelity in the Tent-Making Bat Artibeus watsoni
(2007-05)Roost switching is a common occurrence in bats, yet the causes and consequences of such behavior are poorly understood. In this study we explore the ecological correlates of roost fidelity in the tent‐making bat Artibeus ... -
Ecological Networks between Tent-Roosting Bats (Phyllostomidae: Stenodermatinae) and the Plants Used in a Neotropical Rainforest
(2018)Roost ecology in bats is a complex interaction of behavioral, morphological and physiological adaptations, thus, there are many factors involved in roost selection by bat species. Approximately 22 species of bats are able ... -
Ecological patterns of Costa Rican myxomycetes
(2009-10)Ecological patterns of tropical myxomycetes have been subjected to study only during the last decade. An exhaustive analysis of an extensive dataset for a single tropical country is lacking. For this reason, the present ... -
Ecological patterns of lignicolous myxomycetes from two different forest types in Costa Rica
(2015-04-21)Lignicolous myxomycetes comprise an ecological guild that has been extensively studied in temperate areas. However, there is still incomplete information about the group for the tropics and thus, with the objective to ...
