Combining Adequate BRUV Deployment Times with Individual Photo-Identification Improves Monitoring of Shark Populations in the Caribbean Open
Sharks play a key role in coral reef ecosystems, but Caribbean populations are concerningly low. When monitoring endangered species, it is critical to use minimally invasive tools and protocols that are adequate for local species and the e…

Elevated sea surface temperatures drive greater seasonal depth use in a baited aggregation of silky sharks Carcharhinus falciformis Open
Conservation plans for pelagic sharks in future climate scenarios are limited by a lack of empirical data on behavioral responses to sustained elevated temperatures. The relatively high sea surface temperatures observed in the Red Sea prov…
