The Journal of Wildlife Management, Volume 90, Issue 1, January 2026.We present an approach for estimating wildlife abundance from unstructured aerial surveys. We combine a spatial model for count data with auxiliary information on detection probability. This framework is intended to be flexible, requiring lower survey costs and less computation time than other alternatives for estimating abundance.

Color Vision in the Manatee (Trichechus manatus)
Vision Research, 1996 Four manatees were trained to discriminate between a colored stimulus and a shade of gray in a two-fold simultaneous choice situation. The colors blue, green, red and blue-green were tested against shades of gray varying from low to high relative brightness. The animals distinguished both blue and green from a series of grays but failed to discriminate

Do Marine Mammals Diversify More Slowly Than Non‐Marine Mammals?
Journal of Biogeography, Volume 53, Issue 1, January 2026.ABSTRACT Aim Species richness is generally lower in marine than in terrestrial ecosystems, but the reasons behind this disparity remain unclear. This study examines whether marine mammals diversify at a slower pace than their non‐marine counterparts, aiming to shed light on the factors explaining potential diversification differences among them ...
