Representation of vocalizations in the frontal auditory field and the dorsal auditory cortex of bats. [PDF]

Ann N Y Acad Sci
This study investigated the specificity of encoding for different types of vocalizations in neurons of the frontal auditory field (FAF) and the dorsal auditory cortex (dAC) of a bat. Our results show that dAC neurons were more selective for call categories and single calls than neurons in the FAF. This contrasts with earlier findings and highlights the

DNA Methylation Dynamics Reflect Sex and Status Differences in Mortality Rates in a Polygynous Bat. [PDF]

Mol Ecol
ABSTRACT Males of polygynous mammals often do not live as long as females and, in some cases, exhibit evidence of earlier senescence. Patterns of DNA methylation (DNAm) have recently been used to predict chronological age in mammals. Whether DNAm also changes as a consequence of survival and senescence is largely untested in wild animals. In this study,

Trypanosoma cruzi-like bloodstream trypomastigotes in bats from the State of Piauí, Northeastern Brazil

Revista da Sociedade Brasileira de Medicina Tropical, 1986
One-hundred and thirty-five bats from 12 species were examined for thepresence of trypomastigotes by means of direct blood examination, xenodiagnosis, and hemoculture.

Representation of three-dimensional space in the auditory cortex of the echolocating bat P. discolor. [PDF]

PLoS ONE, 2017
The auditory cortex is an essential center for sound localization. In echolocating bats, combination sensitive neurons tuned to specific delays between call emission and echo perception represent target distance. In many bats, these neurons are organized

Genome Mining and Structural Study of Cathelicidins Across Chiroptera Species. [PDF]

Biochem Res Int
The authors explored the genomic landscape of bat cathelicidins, critical proteins in the vertebrate innate immune system, across 41 bat species, which are notable for their high microbial tolerance. An array of bioinformatics tools, complemented by manual mining, were used to identify the curated cathelicidin sequences.

Biological clocks as age estimation markers in animals: a systematic review and meta‐analysis

Biological Reviews, Volume 98, Issue 6, Page 1972-2011, December 2023., 2023
ABSTRACT Various biological attributes associated with individual fitness in animals change predictably over the lifespan of an organism. Therefore, the study of animal ecology and the work of conservationists frequently relies upon the ability to assign animals to functionally relevant age classes to model population fitness.

What noseleaves do for FM bats depends on their degree of sensorial specialization. [PDF]

PLoS ONE, 2010
BACKGROUND: Many bats vocalizing through their nose carry a prominent noseleaf that is involved in shaping the emission beam of these animals. To our knowledge, the exact role of these appendages has not been thoroughly investigated as for no single ...

The Vocal Repertoire of Pale Spear-Nosed Bats in a Social Roosting Context

Frontiers in Ecology and Evolution, 2019
Commonly known for their ability to echolocate, bats also use a wide variety of social vocalizations to communicate with one another. However, the full vocal repertoires of relatively few bat species have been studied thus far. The present study examined

Communication breakdown: Limits of spectro-temporal resolution for the perception of bat communication calls

Scientific Reports, 2021
During vocal communication, the spectro-temporal structure of vocalizations conveys important contextual information. Bats excel in the use of sounds for echolocation by meticulous encoding of signals in the temporal domain.
