The bathypelagic zone, despite being the largest cumulative ecosystem on the planet, represents the largest data gap in biological oceanography. In a deep environment with no solar light and pressures so high that survival is impossible for most marine organisms, some species have been able to adapt and overcome these challenges to radiate into diverse and successful taxa. Among the most notable of these successful taxa are the deep-sea anglerfishes (Lophiiformes: Ceratioidei). Ceratioid anglerfishes possess unique adaptations such as a symbiotic bioluminescent lure (females) and extreme dwarfism (males) that make them a particularly interesting group to study. Despite this research …
Trophic Ecology Of A Dominant Mesopredatory Fish Family (Alepisauridae) In The Western North Atlantic Revealed By Stomach Content And Stable Isotope Analysis, Ellyn Willse

The mesopelagic zone of the ocean is gaining increased notice due to its potential for commercial value and the lack of knowledge of its ecosystems. Lancetfishes, Alepisaurus spp., are large mesopelagic predators and common bycatch species in commercial fishing operations that potentially play a role in connecting epipelagic and mesopelagic waters and may be a source of carbon from near the surface to the mesopelagic. While little is known about the behavior and biology of Lancetfishes, they share many food sources, and are themselves a food source for important commercial fisheries species such as tuna and swordfish. This study examines …
Resource Allocation And Phenotypic Plasticity Of Simultaneous Hermaphroditic Turtle Barnacles (Chelonibia Testudinaria), Kevin C. Cash
Resource Allocation And Phenotypic Plasticity Of Simultaneous Hermaphroditic Turtle Barnacles (Chelonibia Testudinaria), Kevin C. Cash

This research addresses the knowledge gap of phenotypic plasticity in a commonly found and important species of epizoic barnacle, Chelonibia testudinaria. Limited research has been published regarding how phenotypic expression is mediated the spatial distribution of barnacles on a mobile host. To investigate this potential relationship, barnacles were collected from the backs of turtles along the beaches of Fort Lauderdale Florida. These barnacles were assessed for various phenotypic traits as well as their corresponding spatial distribution on the turtle carapace. Barnacles were safely removed from the carapace using a chisel before their preservation in ethanol. Barnacles were then numbered …
