Ultrastructure of spermiogenesis in the American alligator,Alligator mississippiensis(Reptilia, Crocodylia, Alligatoridae)

Journal of Morphology, 2010
AbstractTesticular samples were collected to describe the ultrastructure of spermiogenisis inAlligator mississipiensis(American Alligator). Spermiogenesis commences with an acrosome vesicle forming from Golgi transport vesicles. An acrosome granule forms during vesicle contact with the nucleus, and remains posterior until mid to late elongation when it

Conservation Status of Caiman latirostris (Crocodylia: Alligatoridae) in Disturbed Landscapes of Northwestern Uruguay

South American Journal of Herpetology, 2008
Abstract Demographic studies on crocodilians in subject to strong human disturbance habitats are scarce, particularly in the Neotropical Region. This work provides the first survey data of abundance and population size structure of a neotropical caiman, Caiman latirostris, in disturbed habitats of northwestern Uruguay (30°S, 57°W).

Revisiting the thermoregulation hypothesis of osteoderms : a study of the crocodilian **Paleosuchus palpebrosus** (Crocodilia: Alligatoridae)

2022
Abstract: The functional significance of osteoderms-ossified bony structures in the dermis-has been a topic of discussion for many years in biological sciences. Although a protective function has received significant attention in the past, evidence is accumulating that osteoderms might play an important role during physiological activities ...
