Environmental variability plays a crucial role in shaping the site use of apex predators, yet its influence under human-modified conditions remains unclear. From August 2021 to March 2024, we conducted 911 visual surveys of tiger sharks ( Galeocerdo cuvier ) at Fuvahmulah, Maldives. We used photo-ID to identify individual tiger sharks, and agglomerative hierarchical clustering to classify sharks into residency clusters. We fit...

Marine protected areas (MPAs) are common conservation tools supporting the protection of threatened marine fishes, such as sharks. However, the creation of shark MPAs has been less common in the Greater Caribbean region despite a growing need and opportunity. In this study, we evaluated the occurrence of shark and reef fish biodiversity off Sint Maarten, Dutch Caribbean, with a particular emphasis on endangered shark presence...

The reproductive state of wild, free-swimming tiger sharks ( Galeocerdo cuvier) , was assessed using underwater ultrasonography at a diving site in Fuvahmulah, a Maldivian atoll within the central Indian Ocean. The presence of embryos were observed in 93% of the adult sharks (26/28) and two distinct embryonic size groups were observed within the subset of scanned adult females. The results suggest that the observed dive site f...
