Seagrasses in the age of sea turtle conservation and shark overfishing
Michael R. Heithaus,Teresa Alcoverro,Teresa Alcoverro,Rohan Arthur,Derek A. Burkholder,Kathryn A. Coates,Marjolijn J. A. Christianen,Nachiket Kelkar,Sarah A. Manuel,Aaron J. Wirsing,W. Judson Kenworthy,James W. Fourqurean +11 more
TL;DR: It is suggested that overfishing of large sharks, the primary green turtle predators, could facilitate turtle populations growing beyond historical sizes and trigger detrimental ecosystem impacts mirroring those on land when top predators were extirpated, including triggering virtual ecosystem collapse.
Journal ArticleDOI
Coexistence of Fisheries with River Dolphin Conservation
Nachiket Kelkar,Nachiket Kelkar,Jagdish Krishnaswamy,Jagdish Krishnaswamy,Sunil Kumar Choudhary,Dipani Sutaria +5 more
TL;DR: Fish-stock restoration and management, effective monitoring, curbing destructive fishing practices, secure tenure rights, and provision of alternative livelihoods for fishers may help reconcile conservation and local needs in overexploited river systems.
Journal ArticleDOI

TL;DR: In this paper, the threats faced by marine mammals and the conservation mechanisms available to address them are evaluated and discussed, as well as evidence-based priorities of both research and conservation needs across a range of settings and taxa.
Journal ArticleDOI
Greener pastures? High-density feeding aggregations of green turtles precipitate species shifts in seagrass meadows
TL;DR: The results show that high-impact turtle herbivory changes seagrass composition, precipitating dominance shifts in grazed meadows by mediating direct and apparent competition, and suggest that past meadows may have had natural functional limits to megaherbivore densities that they could sustainably support.
Journal ArticleDOI
River dolphin distribution in regulated river systems: implications for dry‐season flow regimes in the Gangetic basin
Sunil Kumar Choudhary,Sushant Dey,Subhashish Dey,Viveksheel Sagar,Tarun Nair,Nachiket Kelkar,Nachiket Kelkar +6 more
TL;DR: In this article, the authors investigated the habitat use of river dolphins in relation to river channel depth and morphology, over 332 km of the flow-regulated Gandak River in India and found that river dolphin abundance was positively influenced by river depth, presence of meanders and corresponded closely with gillnet fishing.
