Phylogenetic systematics, biogeography, and evolutionary ecology of the true crocodiles (Eusuchia: Crocodylidae: Crocodylus) [PDF]

open access: yes, 2007
Modern crocodylian systematics has been dominated by investigations of higher-level relationships aimed at resolving the disparity between morphological and molecular data, especially regarding the true gharial (Gavialis).

Egg predation and vertebrates associated with wild crocodilian nests in Mexico determined using camera-traps [PDF]

open access: yes, 2021
Interactions between species and individuals can determine their survival in the wild. Most of the time these relationships are difficult to study in situ by direct observation.

The Case of the Missing Green Iguana Predators: Reviews of Ecological Literature Should Go Beyond Google Scholar

open access: yesThe Bulletin of the Ecological Society of America, EarlyView.
Abstract Knowing about species interactions is essential for ecological research, conservation efforts, resource management, and maintaining healthy ecosystems, but many of these, such as reports of predation, may not always be published in easily located resources—if they are published at all.

Quadrate orientation and joint reaction force underwent correlated evolution during suchian evolution

open access: yesJournal of Anatomy, EarlyView.
The quadrate is the cranial bone of the nonmammalian jaw joint. The quadrate has long been hypothesized to mirror the direction of joint reaction forces (JRF) during feeding. This study uses 3D biomechanical modeling to reveal a striking evolutionary link between quadrate orientation and JRF direction, unlocking new insights into the dynamic forces ...

Organochlorine Pesticides in Chlorioallantoic Membranes of Morelet\u27s Crocodile Eggs from Belize [PDF]

open access: yes, 2004
Recent studies examined the utility of the chorioallantoic membrane (CAM) as a nonlethal, noninvasive indicator of environmental contaminant exposure in oviparous wildlife. The CAM is a highly vascularized extraembryonic membrane that functions as a site

Testing the Utility of Gaussian Mixture Models in Parataxonomic Classification of Fossil Eggs [PDF]

open access: yes, 2021
Fossil eggs and eggshells are very seldom associated with skeletal or dermal remains and can rarely be assigned taxonomically. This has resulted in oologists creating an alternative classification system for fossil eggs and eggshells: the parataxonomy of

Predictors and immunological correlates of sublethal mercury exposure in vampire bats [PDF]

open access: yes, 2017
Mercury (Hg) is a pervasive heavy metal that often enters the environment from anthropogenic sources such as gold mining and agriculture. Chronic exposure to Hg can impair immune function, reducing the ability of animals to resist or recover from ...
