Morphological Variation Of Lingual Glands In Wild American Alligator (Alligator Mississippiensis) Populations, Benjamin Angalet
Morphological Variation Of Lingual Glands In Wild American Alligator (Alligator Mississippiensis) Populations, Benjamin Angalet
Master's Theses
American alligators (Alligator mississippiensis) inhabit diverse aquatic ecosystems including freshwater wetlands, swamps, and estuarine rivers. As apex predators, their physiological resilience has implications for ecosystem stability and long-term conservation. With projected sea-level rise and increasing saltwater intrusion into coastal freshwater habitats, understanding the osmoregulatory capacity of alligators is increasingly important. Unlike marine-tolerant crocodilians such as the saltwater crocodile (Crocodylus porosus), which possess specialized salt-secreting lingual glands in addition to renal and cloacal mechanisms, the morphology and physiological significance of lingual glands in wild American alligators remain poorly understood. This study examined lingual gland morphology and plasma …

Assessing The Osmoregulatory Capabilities Of American Alligator Lingual Glands, Benjamin Angalet, Nicholas S. Green
Symposium of Student Scholars
Crocodilians inhabit a wide variety of aquatic, marine, and estuarine habitats on 4 continents. Saltwater-adapted species and populations face considerable osmoregulatory challenges in maintaining homeostasis with respect to plasma salt [NaCl] concentration. In addition to the kidneys and cloaca found in all crocodilians, crocodiles possess a salt-secreting lingual gland whose presence and function is less understood in other crocodilians. This study investigates the lingual gland anatomy, physiology, and potential function of American alligator (Alligator mississippiensis) populations exposed to varying salinity levels. At each of four sites (Jekyll Island, Sapelo Island, Okefenokee NWR, and Banks Lake NWR), we will capture 12 …
Patterns And Potential Mechanisms Of Phenotypic Changes In Urban Small Mammals, Leslie Lopez
Patterns And Potential Mechanisms Of Phenotypic Changes In Urban Small Mammals, Leslie Lopez
Master's Theses
Urbanization is an example of human induced rapid environmental change that can have wide-reaching ecological effects, including habitat destruction, fragmentation, and alteration of local climates. Effects of urbanization have been shown to impact wildlife, as disturbances resulting from urbanization can create novel environments and selective pressures that could lead to changes in morphology, physiology, or both. Small mammals such as rodents are an ecologically important set of wildlife species because they are a key prey item for several predators, hold strong influence over plants as a primary consumer, and some species carry and transmit major human and animal diseases.
