Human waste used as nesting material affects nest cooling in the clay-colored thrush
(2021-09-01)
The internal temperature of nests largely depends on the materials used in their construction because the characteristics of each material affect the isolation of nest walls. In urban environments, the availability of
natural ...

Informamos la existencia de tres híbridos silvestres de patos en Costa Rica, basados en observaciones esporádicas en el país. Adicionalmente, proveemos una explicación de cuáles, serían las especies que dieron origen a ...
The influence of leaf characteristics on epiphyllic cover: A test of hypotheses with artificial leaves
(1995-12-31)
Studies of epiphyll ecology have been hindered by the biochemical and morphological variability of the leaf substrate. The use of artificial (plastic ribbon tape) leaves solved that problem in a study done at the Braulio ...

A test of the Acoustic Adaptation Hypothesis in three types of tropical forest: degradation of male and female Rufous-and-white Wren songs
(2016)
Many animals produce complex vocalizations that show pronounced variation between populations. The Acoustic Adaptation Hypothesis helps to explain this variation, suggesting that acoustic signals are optimized for transmission ...
