Article Synopsis
  • The study examines the population structure of Bull Sharks globally, revealing reproductive isolation among different ocean basins and distinct island populations, such as those in Japan and Fiji.
  • Through advanced DNA analysis, researchers found that Bull Sharks use shallow coastal waters for dispersal, while geographical barriers limit gene flow, which impacts their conservation.
  • The findings highlight the vulnerability of local Bull Shark populations to overfishing, particularly among females that return to specific breeding areas, emphasizing the need for targeted management strategies to prevent local declines.

Article Synopsis
  • * Research using baited remote underwater video systems in the Caribbean showed that market gravity positively influences moray eel populations, while negatively impacting other exploited predators like sharks.
  • * Environmental DNA analysis supports the finding that market gravity benefits morays, suggesting that this might stem from a decrease in their competitors and predators near human activities.

Animal dietary information provides the foundation for understanding trophic relationships, which is essential for ecosystem management. Yet, in marine systems, high-resolution diet reconstruction tools are currently under-developed. This is particularly pertinent for large marine vertebrates, for which direct foraging behaviour is difficult or impossible to observe and, due to their conservation status, the collection of stomach contents at adequate sample sizes is frequently impossible.

The integration of eDNA analysis into the population assessment and monitoring of sharks could greatly improve temporal and spatial data used for management purposes. This study aimed to compare eDNA detection against well-established seasonal changes in blacktip shark (Carcharhinus limbatus) abundance in Terra Ceia Bay (FL, USA). We used a species-specific real-time PCR approach to detect C.
