Actin is a key component of the cytoskeleton and also plays diverse roles within the cell nucleus. While polymerized F-actin can be detected using a wide range of probes, reliable methods to identify unpolymerized (“G-”) actin in fixed cells are relatively limited. Fluorescently labeled DNase I has long served as a high-affinity probe for monomeric actin and has recently gained renewed interest in nuclear actin research. Here,...

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. Here, we integrate discoveries from laboratory research on auditory sensory processes and...

Cognition is an animal's real‐time adaptation system for responding to change. Rapid environmental change, often anthropogenic, is expanding the range and severity of challenges confronting wild animals. Effective conservation requires a multifaceted approach that includes animals' capacities. Large‐brained, long‐lived animals such as marine mammals often have extensive capability to adaptively modify their behavior due to the...
