Seasonal Foraging Behavior of the Frugivorous Bat Carollia perspicillata

Journal of Mammalogy, 1986
(Uploaded by Plazi for the Bat Literature Project) We studied the foraging behavior of the frugivorous bat Carollia perspicillata (Phyllostomidae)during two dry seasonsand two wet seasons in northwesternCosta Rica using radio-telemetry and capture-recapture techniques.

From steps to home ranges: How habitat disturbance influences the movement drivers of an arboreal primate

Journal of Animal Ecology, EarlyView.
Challenging the narrative about howler monkeys' high resilience to anthropogenic changes, our multiscale analysis reveals the costs of habitat disturbance to their movement ecology. We identify thermal limitations, reduced travel efficiency, and significant spatial saturation.

An Experimental Analysis of the Food Location Behavior of Frugivorous Bats

Ecology, 1977
Models of optimal foraging often separate the time and energy expended in getting to a feeding area (commuting costs) from the time and energy expended in searching for food (search costs) in animals that are "pure searchers." We predict that under certain circumstances (e.g., a relatively uniform resource distribution) searching and commuting behavior

Molecular detection of Histoplasma capsulatum in insectivorous and frugivorous bats in Southeastern Brazil [PDF]

Medical Mycology, 2017
(Uploaded by Plazi for the Bat Literature Project) Bats are considered to play a significant role in the epidemiology of histoplasmosis, worldwide. We investigated the occurrence of H. capsulatum in lung samples from 89 bats, from urban areas in Southeastern Brazil, using nested PCR based on ribosomal DNA. Fungal DNA was detected in 31/89 samples (34.8%

Adaptive evolution in the glucose transporter 4 gene Slc2a4 in Old World fruit bats (family: Pteropodidae). [PDF]

PLoS ONE, 2012
Frugivorous and nectarivorous bats are able to ingest large quantities of sugar in a short time span while avoiding the potentially adverse side-effects of elevated blood glucose. The glucose transporter 4 protein (GLUT4) encoded by the Slc2a4 gene plays

Vitamin C Levels in Different Organs of Bat Species from Different Food Groups

Life, 2022
Unlike most animals, most bats cannot synthesize vitamin C endogenously. Consequently, this vitamin must be obtained from the diet. Among the bat species, there are several food groups, such as frugivorous, nectarivorous, insectivorous, and hematophagous.

Ground mammal colonization of restored wildlife corridors in the tropical uplands of north‐eastern Australia

Restoration Ecology, EarlyView.
Abstract Introduction Since European settlement, Australia's Wet Tropics bioregion has been extensively cleared, leaving a mosaic of rainforest fragments, crops, pastures, orchards, and human settlement. Fragment isolation leads to declines in faunal diversity and genetic variability, effects potentially exacerbated by climate change. Restoring habitat

Relaxed evolution in the tyrosine aminotransferase gene tat in old world fruit bats (Chiroptera: Pteropodidae). [PDF]

PLoS ONE, 2014
Frugivorous and nectarivorous bats fuel their metabolism mostly by using carbohydrates and allocate the restricted amounts of ingested proteins mainly for anabolic protein syntheses rather than for catabolic energy production.

Effects of Temperature Peaks and Water Stress on Tropical Seed Germination: Experimental Trials With Species From Brazil's Northeastern Coastal Zone

Biotropica, Volume 58, Issue 5, September 2026.
ABSTRACT Understanding the effects of high temperatures and water deficit on germination provides valuable insights into seed stress tolerance, guiding the use of native seeds in ecological restoration. This study aimed to evaluate the effects of (1) temperature peaks and (2) water stress treatments and post‐stress recovery on the germination of some ...

A roadmap to key traits of invasive Drosophilidae

Biological Reviews, Volume 101, Issue 4, Page 1805-1829, August 2026.
ABSTRACT Biological invasions have intensified in recent decades, mostly driven by international trade and travel, raising significant concerns, particularly regarding insect pests. Once non‐native species establish, they can disrupt natural ecosystem stability, undermine agroecosystem sustainability and cause substantial economic losses.
