Resource use overlap in a native grouper and invasive lionfish... For this thesis, I conducted two studies designed to elucidate the strength of resource use overlap and potential competition among invasive lionfish and an ecologically similar serranid, the Graysby (Cephalopholis cruentata), along a contiguous coral-reef ledge in Biscayne National Park, South Florida.My...
Lionfish prey preference between native basslets... I investigated lionfish and native graysby grouper prey preference between prey species and prey size using two closely-related and potentially competitive prey species, the fairy basslet and blackcap basslet....
Feeding ecology of the invasive lionfish (pterois spp.) and comparison with two native species: schoolmaster lutjanus apodus (walbaum, 1792) and graysby cephalopholis cruentata (lacepède, 1802)Predator satiation and prey-size preference were determined for locally caught lionfish, schoolmaster, and graysby, all co-occurring predatory fishes in the Florida coral reef ecosystem....
