Cognition as a Conservation Tool: A Case Study of Florida Manatees and Boat Strikes

open access: yesMarine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Boat strikes injure and kill large numbers of Florida manatees (Trichechus manatus latirostris) each year. Management actions taken to mitigate this threat can be potentially enhanced by consideration of manatee cognitive processes. The role of cognition in marine mammal conservation has received little consideration in the literature.

Optimizing Total Suspended Solids Mitigation in a Data‐Limited Watershed: A Network‐Based Advection–Reaction Model Applied to the Canal del Dique, Colombia

open access: yesWater Resources Research, Volume 62, Issue 2, February 2026.
Abstract Total Suspended Solids (TSS) significantly degrade water quality by reducing light penetration and oxygen availability, while facilitating the transport of toxic contaminants. Managing TSS in watersheds requires an understanding of both hydrological connectivity and pollutant dynamics; however, these efforts are significantly constrained by ...
