Who Is Served First? Intraspecific Traits That Drive Arrival at Food Resource in Two Phanaeus (Coleoptera: Scarabaeinae) Species

Austral Ecology, Volume 51, Issue 1, January 2026.
ABSTRACT Intra‐ and interspecific interactions may structure complex competitive scenarios in which the arrival time at a resource may play a key role in determining how individuals and populations are maintained. The speed and efficiency by which the dung beetles locate and colonise dung pads, which comprise an ephemeral and randomly distributed ...

Ecological Niche Differences Underlie the Assembly of Endemic Birds in Acrobiont Forests of Northern Mesoamerica

Journal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim The study of the structure of species assemblages has typically assumed that similar environments share common species; however, interacting biogeographic and phylogenetic processes are equally important. The understanding that ecological processes operate at different spatial scales to shape species assemblages led to the concept of ...

Anatase–Gentamicin Electrophoretic Coatings on Polyurethane‐Modified Titanium: Antibacterial Performance, Biocompatibility, and Drug Delivery

International Journal of Biomaterials, Volume 2026, Issue 1, 2026.
Infections, limited biocompatibility, and material degradation remain major challenges for metallic implants in biomedical applications. To address these issues, this study presents a multifunctional coating strategy for Grade 2 titanium using a base layer of segmented polyurethane (Tecoflex SG‐80A), followed by the co‐deposition of titanium dioxide ...
