An updated checklist of Culicoides Latreille, 1809 biting midges from the highlands of eastern Democratic Republic of the Congo Une liste mise à jour des moucherons piqueurs de Culicoides Latreille, 1809 des hautes terres de l'est de la République démocratique du Congo

open access: yesMedical and Veterinary Entomology, EarlyView.
The highlands of eastern Democratic Republic of the Congo (DRC) are home to critically endangered eastern gorillas (Gorilla beringei). Climate change could increase the abundance and distribution of Culicoides‐borne diseases. We utilized morphological and molecular techniques to identify Culicoides spp.

Canalized to heat, plastic to cold: adaptive coordination of leaf and seed strategies in populations spanning an elevational gradient

open access: yesNew Phytologist, EarlyView.
Summary In tropical mountains, surviving temperature extremes demands finely tuned strategies. We investigated how populations of the bromeliad Pitcairnia flammea across a 2200 m elevational gradient balance genetic canalization and plasticity, and whether thermal strategies are coordinated between seeds and leaves.

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

open access: yesBiotropica, 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.

Impacts of bat use of anthropogenic structures on bats and humans

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract Human‐induced landscape modifications and climate change are forcing wildlife into closer contact with humans as the availability of natural habitats decreases. Although the importance of anthropogenic structures for the conservation of species is widely recognized, negative narratives surrounding bats may impede conservation efforts in human ...
