Responses to Scent Marks in a Wild Group of Leontocebus Weddelli: Insights for Sexual Communication

American Journal of Primatology, Volume 88, Issue 5, May 2026.
In wild saddleback tamarins, scent marks from the adult breeding female elicited the highest response numbers and received the most overmarks from adult breeding males. Together, these findings suggest that olfaction mediates sexual communication in mate attraction and/or mate guarding.

Optimization of Parsimonious and Synchronized Discharge and Dissolved Organic Carbon Models Across Catchment Scales

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract The production, transport, loss, and export of dissolved organic carbon (DOC) are closely connected with hydrometeorological drivers. While terrestrial production depends on biogeochemical variables like soil moisture, air temperature, and the contact area between water and organic matter sources, export is determined by water availability and

A new phylogeny of Anastrepha (Diptera: Tephritidae) based on nuclear loci obtained by phylogenomic methods

Systematic Entomology, Volume 51, Issue 1, January‐March 2026.
We present an extensive phylogenetic analysis, based on 293 nuclear loci and 728 individuals representing 237 species of Anastrepha, the largest and most economically important New World genus of Tephritidae. The analysis strongly supports the monophyly of most Anastrepha species groups, also revealing previously unknown relationships among species and
