Do Energetic Challenges Mimicking Missed Foraging Encourage Torpor Use by a Neotropical Bat?

Biotropica, Volume 58, Issue 2, March 2026.
We experimentally tested whether Merriam's long‐tongued bat (Glossophaga mutica), a Neotropical nectarivorous species, uses heterothermy in response to reduced energy intake. We found that energetically challenged bats maintained subcutaneous temperatures significantly closer to roost temperature during the daytime inactive period.

Stratégies d’exploitation en zones inondables tropicales

, 2002
Les zones inondables tropicales sont souvent des milieux traditionnellement exploités par l'homme. Pêcheurs, éleveurs, agriculteurs, forestiers et autres sillonnent les milieux inondables dans lesquels les ressources naturelles renouvelables sont abondantes. Les habitants de ces zones ont su pérenniser un mode de vie et d'exploitation en équilibre avec

Soil Properties and Plant Species Identity Independently Influence Arbuscular Mycorrhizal Fungal Composition Across Lowland Tropical Forests

Biotropica, Volume 58, Issue 2, March 2026.
We found that plant species identity and soil properties, especially soil phosphorus availability, independently structured arbuscular mycorrhizal fungal (AMF) community composition in tropical forests across central Panama. We also found that soil nutrient availability may mediate the interaction networks between plants and AMF. ABSTRACT Plant species

Pests for Dinner: Dietary Composition of Insectivorous Bats in a Fragmented Tropical Dry Forest

Biotropica, Volume 58, Issue 2, March 2026.
Insectivorous bats are key predators of a wide array of arthropods, including species that act as disease vectors and pests, yet such ecological roles remain poorly studied in tropical regions. In this study, we aimed to describe the diet of five insectivorous bat species from the genera Balantiopteryx, Myotis, Mormoops, and Pteronotus inhabiting a ...

Nocturnal Gardeners: Dispersal of Large Seeds by Tent‐Roosting Bats in the Lacandon Rainforest, Mexico

Biotropica, Volume 58, Issue 2, March 2026.
Tent‐roosting bats in the Lacandon Forest, Mexico, play a previously undocumented role in dispersing large seeds (> 5 mm) from mature forest species with important ecological and human uses. Sampling 21 feeding tents across two protected areas yielded 2137 seeds from 54 species, with seed deposition rates significantly higher under bat tents than in ...

Trees Inside and Outside of Forests in Guanacaste, Costa Rica: Comparisons Among Conservation Areas, Fencerows, and Urban Parks

Biotropica, Volume 58, Issue 2, March 2026.
We compared the abundance and characteristics of trees in replicated plots across a rural to urban gradient in Guanacaste, Costa Rica. Trees in urban parks, fencerows, and national parks provide complementary benefits and have distinct compositions.

Unraveling the Phenology of the Liana Marcgravia longifolia: Temporal Patterns and Climatic Cues

Biotropica, Volume 58, Issue 2, March 2026.
We monitored the reproductive phenology of the Amazonian liana Marcgravia longifolia J. F. Macbr (Marcgraviaceae) for 84 consecutive months in the Peruvian Amazon to quantify the timing, synchrony, and seasonality of flowering and ripe fruiting. Flower presence peaked in August with intermediate synchrony, while ripe fruit presence peaked in November ...
