Selection and trans-species polymorphism of major histocompatibility complex class II genes in the order Crocodylia. [PDF]
PLoS ONE, 2014 Major Histocompatibility Complex (MHC) class II genes encode for molecules that aid in the presentation of antigens to helper T cells. MHC characterisation within and between major vertebrate taxa has shed light on the evolutionary mechanisms shaping the

Agricultural input modifies trophic niche and basal energy source of a top predator across human-modified landscapes [PDF]
Frontiers in Ecology and Evolution, 2023 Land-use conversion and resulting habitat fragmentation can affect the source(s) of primary productivity that fuels food webs and alter their structure in ways that leads to biodiversity loss. We investigated the effects of landscape modification on food

Temperature variation in nests of Caiman crocodilus (Crocodylia: Alligatoridae)
Acta Herpetologica, 2007 Caiman crocodilus is a widely distributed species in the Neotropics; however, studies of incubation temperatures in wildlife are uncommon. Incubation temperature in four nests of Caiman crocodilus were measured with a digital thermometer, in the National

Comparative analysis of cranial suture complexity in the genus Caiman (Crocodylia, alligatoridae) [PDF]
Revista Brasileira De Biologia, 2000 The variation in degrees of interdigitation (complexity) in cranial sutures among species of Caiman in different skull regions was studied by fractal analysis. Our findings show that there is a small species effect in the fractal dimension of cranial sutures, but most variation is accounted for by regional differentiation within the skull.

Cloacal mycobiota in wild females of Caiman latirostris (Crocodylia: Alligatoridae)
Revista Mexicana de Biodiversidad, 2013 There are few reports of cloacal mycobiota on wild reptiles, and in particular, fungal presence and functionin Caiman latirostris remains unknown. Our objective was to describe the fungal community present in the cloaca ofwild female broad-snouted caimans during their reproductive season determine whether the number of fungi has somerelationship with ...

Embryological development of Caiman latirostris (Crocodylia: Alligatoridae) [PDF]
genesis, 2008 AbstractA standard development embryological series is the primary basis to organize information of any embryological study and is also used to determine the age of eggs and embryos in field conditions. In this article, we calibrate developmental series of the broad‐snouted caiman, Caiman latirostris, against an established series for Alligator ...
