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 ... -
Dos especies nuevas de Orthothrips Priesner (Thysanoptera: Phlaeothripidae) en Costa Rica
(Métodos en Ecología y Sistemática (MES), vol. 3, n. 3, 2008, 2008)Se describen dos especies nuevas pertenecientes al género Orthothrips Priesner en Costa Rica. Estas especies están estrechamente relacionadas con O. boneti Stannard, O. dubius Stannard y O. tepoztlanensis Johansen, sin ... -
Dracontia, the little-known dragon orchids
(2011-09)The dragon orchids (genus Dracontia) represent a small group of mostly Central American species in the Pleurothallidinae. Their relatively large, uniquely shaped and diversely ornate flowers set them apart from their close ... -
Draft Genome Sequences of Two Cyanobacteria Leptolyngbya spp. Isolated from Microbial Mats in Miravalles Thermal Spring, Costa Rica
(2021)We report the draft genome sequences of Leptolyngbya sp. strain 7M and Leptolyngbya sp. strain 15MV, isolated from Miravalles Thermal Spring, Costa Rica. The thermophilic cyanobacteria exhibit unique diversity features ... -
Dry-season leaf flushing of Enterolobium cyclocarpum (ear-pod tree): above- and belowground phenology and water relations
(2007-11)Above- and belowground phenology and water relations of Enterolobium cyclocarpum Jacq. trees in the dry forest of Santa Rosa National Park, Costa Rica were studied during two consecutive phenological cycles, from November ... -
Dual Function of Chip Calls Depending on Changing Call Rate Related to Risk Level in Territorial Pairs of White-Eared Ground-Sparrows
(2017-03)Different mechanisms have been proposed for encoding information into vocalizations: variation of frequency or temporal characteristics, variation in the rate of vocalization production, and use of different vocalization ... -
Duckweeds (Araceae: Lemnoideae) growing on wet, vertical rocks behind a waterfall in Costa Rica, with a new country record of Wolffiella oblonga (Phil.) Hegelm.
(2019)A large colony of duckweeds (Araceae: Lemnoideae) grows on the constantly wet, vertical wall of the rock shelter behind the Llanos de Cortés waterfall of the Potrero River, Guanacaste province, Costa Rica, the first such ... -
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 ... -
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 ... -
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 ... -
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 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 ...
