Morphology of the male reproductive duct system of Caiman crocodilus (Crocodylia, Alligatoridae)

Annals of Anatomy - Anatomischer Anzeiger, 2004
The male reproductive duct system of Caiman crocodilus in different reproductive stages was studied using light and electron microscopy, to determine whether shared morphological features exist between Crocodylia and Aves, in concurrence with the Archosauria hypothesis.

MONITORANDO AS INTERAÇÕES ENTRE HUMANOS E JACARÉS (CROCODYLIA: ALLIGATORIDAE) EM MANAUS

Anais do II Congresso Brasileiro de Biodiversidade Virtual, 2022
Introdução: Jacarés (Crocodylia: Alligatoridae) são representantes da fauna que persistiram nos ambientes aquáticos alterados pelo crescimento urbano desordenado na cidade de Manaus (AM) e a convivência com seus habitantes, demanda atenção. Desde 2014 o Laboratório de Manejo de Fauna do INPA tem monitorado as interações entre humanos e jacarés (HJ) a ...

Ontogeny of the Appendicular Skeleton inMelanosuchus niger(Crocodylia: Alligatoridae)

Zoological Science, 2016
The objective of the present study was to analyze chondrogenesis and the ossification pattern of the limbs of Melanosuchus niger in order to contribute with possible discussions on homology and the fusion pattern of autopodial elements and phylogeny. In the Reserva Extrativista do Lago Cuniã, Rondônia, Brazil, six nests were marked and two eggs removed

Revisitando a diversidade e estrutura genética de Caiman Latirostris (Alligatoridae: Crocodylia) no Brasil

Revista Científica Faesa, 2023
The distribution of the broad-snouted caiman is concentrated in the Brazilian coastal area, the area with the highest urbanization rate in the country. The anthropic pressure makes constant monitoring a necessary effort. Aiming to conserve the species and expand genetic information of Caiman latirostris, we analyzed the genetic ...

Climatic effects on the reproductive biology of Caiman latirostris (Crocodylia: Alligatoridae)

Amphibia-Reptilia, 2011
Abstract Reproductive aspects, like number of nests produced per season or clutch size (number of eggs per nest), of broad-snouted caiman ( Caiman latirostris ) may be affected by a climatic variables such as rainfall and temperature. The success

Molecular and functional characterization of BAFF from the Yangtze alligator (Alligator sinensis, Alligatoridae)

Zoology, 2015
B-cell activating factor (BAFF) from the TNF family is critical for B-cell survival and maturation. In this study, we identified a Yangtze alligator (Alligator sinensis, Alligatoridae) BAFF cDNA, designated as asBAFF, using reverse transcription polymerase chain reaction (RT-PCR) and rapid amplification of cDNA ends (RACE).

Ultrastructure of the spermatozoon of the American Alligator, Alligator mississippiensis (Reptilia: Alligatoridae)

Journal of Morphology, 2011
AbstractThis study details the ultrastructure of the spermatozoa of the American Alligator, Alligator mississippiensis. American Alligator spermatozoa are filiform and slightly curved. The acrosome is tapered at its anterior end and surrounded by the acrosome vesicle and an underlying subacrosomal cone, which rests just cephalic to the nuclear rostrum.

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

Two New Eimerians from American Alligator, Alligator mississippiensis (Crocodilia: Alligatoridae), from Georgia, USA

Acta Parasitologica
Little is known about the coccidian parasites of the American alligator, Alligator mississippiensis (Daudin). To date, only two species of Eimeria Schneider, 1875 have been previously reported from A. mississippiensis. Here, we report from mensural and morphometric data on two new species of Eimeria from A.
