Migration of the Butterfly Panacea prola (Nymphalidae: Biblidinae) in the Southeastern Peruvian Amazon

Biotropica, Volume 58, Issue 5, September 2026.
We document an annual dry season migration of the butterfly Panacea prola across a 5‐year period at a lowland Amazonian site in southeastern Peru, adding to our extremely limited knowledge of insect migration in the world's largest and most biodiverse rainforest.

Oro‐Facial Contact Behaviors in Wild White Bald‐Headed Uakaris (Cacajao calvus): First Documentation of Direct Facial Contact and Facial Investigation in Pitheciidae

Biotropica, Volume 58, Issue 5, September 2026.
We document the first instances of direct oro‐facial contact and facial investigation in wild Cacajao calvus. These rare observations expand the social repertoire of Pitheciidae, suggesting that close‐range tactile communication complements the visual signaling of their distinctive red faces.

Soundscapes of the Upper Amazon: Seasonal Activity Patterns of Insectivorous Bats in Cordillera Escalera, Peru

Biotropica, Volume 58, Issue 5, September 2026.
ABSTRACT Bats, the second most diverse group of mammals, play essential ecological roles in insect control, pollination, and seed dispersal. In Peru, insectivorous bats remain poorly studied, particularly in high‐elevation rainforest ecosystems of the upper Amazon region.

Spatial Ecology of Jaguars in a Coastal Amazon Island Ecosystem

Biotropica, Volume 58, Issue 5, September 2026.
ABSTRACTUnderstanding the spatial ecology of large carnivores is critical for conservation, particularly in insular or fragmented systems where movement is constrained. Jaguars (Panthera onca) are especially informative because their behavior and diet are highly flexible in response to local ecological conditions.

Repurposing Legacy Reduced‐Representation Genomic Datasets for Conservation Biogeography: Lessons From Hercules Beetles Across Neotropical Ecoregions

Diversity and Distributions, Volume 32, Issue 9, September 2026.
ABSTRACT Aim The study aimed to explore the opportunities and challenges of repurposing previously published reduced‐representation genomic datasets for conservation biogeography post the Kunming‐Montreal Agreement. Specifically, the study evaluates how historical climate fluctuations, habitat size, and recent anthropogenic disturbances may be ...
