The raphe nuclear organization and serotonergic system in the bat (Artibeus planirostris)

open access: yesJournal of Anatomy, EarlyView.
Schematic representation of the methodological workflow used to characterize the serotonergic (5‐HT) system in the bat Artibeus planirostris. Serotonin (5‐HT) immunohistochemistry was performed on brainstem sections to identify and map the distribution of serotonergic neurons within the raphe nuclei.

Anthropogenic disturbances alter the trophic niche structure and ecological relationships of understory bat communities in the Ecuadorian Andean Chocó

open access: yesWildlife Biology, Volume 2025, Issue 3, May 2025.
Human disturbances have reduced the three basic niche dimensions for the survival of some mammalian species (space, time, and resources). Anthropic activities cause the extinction of ecological functionalities faster than species extinctions. In this study, we identified four types of habitats in the Ecuadorian Andean Chocó: primary forest (PF ...

Seasonal variation and host sex affect bat–bat fly interaction networks in the Amazonian savannahs

open access: yesIntegrative Zoology, Volume 19, Issue 3, Page 400-416, May 2024.
Our data provide information on the interactions between bats and bat flies in one of the largest portions of Brazilian Amazonian savannah. Here, we demonstrate that environmental variations and host sex can influence the structure of interaction networks formed between bats and their ectoparasitic flies. Abstract Bats are the second‐most diverse group

Phenological patterns in ecology: Problems using circular statistics and solutions based on simulations

open access: yesMethods in Ecology and Evolution, Volume 15, Issue 5, Page 868-885, May 2024.
Abstract Quantification of phenological patterns (e.g. migration, hibernation or reproduction) should involve statistical assessments of non‐uniform temporal patterns. Circular statistics (e.g. Rayleigh test or Hermans‐Rasson test) provide useful approaches for doing so based on the number of individuals that exhibit particular activities during a ...

HISTOCHEMICAL ANALYSIS OF THE TONGUE IN NEOTROPICAL FRUGIVOROUS BATS (MAMMALIA – CHIROPTERA) WITH REPORT OF EPITHELIAL PIGMENTATION

open access: yesCiência Animal Brasileira, 2017
The tongue is regarded as a key organ for bats, since the specialized characters are used for taxonomic and systematic purposes, cladistic studies, and elucidation of patterns of eating habits.
