Diving behaviour of a reptile (Crocodylus johnstoni) in the wild: Interactions with heart rate and body temperature [PDF]

, 2005
The differences in physical properties of air and water pose unique behavioural and physiological demands on semiaquatic animals. The aim of this study was to describe the diving behaviour of the freshwater crocodile Crocodylus johnstoni in the wild and ...

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Crocodilian Forebrain: Evolution and Development [PDF]

Integrative and Comparative Biology, 2015
Organization and development of the forebrain in crocodilians are reviewed. In juvenile Caiman crocodilus, the following features were examined: identification and classification of dorsal thalamic nuclei and their respective connections with the telencephalon, presence of local circuit neurons in the dorsal thalamic nuclei, telencephalic projections ...

Habitat selection, parasites and injuries in Amazonian crocodilians

, 1985
Caiman crocodilus is found most frequently in relatively warm, shallow or grassy areas in the larger rivers, lakes and canals of Amazonia. The habitats that it uses are increasing in area because of human activities.

Pulmonary development in Squamata: Insights from embryonic studies using micro‐CT

Developmental Dynamics, EarlyView.
Abstract Background Pulmonary development in tetrapods is a complex process, especially within squamates, where single‐chambered, transitional, and multi‐chambered lungs can be found in adult animals. While the embryological development of the respiratory system of lizards and snakes was studied in a number of species between the 1830s and 1940s, the ...

Comparison of beam theory and finite-element analysis with in vivo bone strain data from the alligator cranium [PDF]

, 2005
The mechanical behavior of the vertebrate skull is often modeled using free-body analysis of simple geometric structures and, more recently, finite-element (FE) analysis. In this study, we compare experimentally collected in vivo bone strain orientations

Biophysical processes of morphogenesis in lizard lungs

Developmental Dynamics, EarlyView.
Abstract Background The lungs of squamate reptiles (lizards and snakes) are highly diverse, exhibiting single chambers, multiple chambers, transitional forms with two to three chambers, along with a suite of other anatomical features, including finger‐like epithelial projections into the body cavity known as diverticulae.

Amphibians and Reptiles of United States Department of Defense Installations [PDF]

, 2018
The U.S. Department of Defense (DoD) occupies approximately 10.1 million ha of land within the U.S. spanning most ecosystems contained therein. To date, no comprehensive agency-wide inventory of amphibian and reptile species has been compiled.

Environmental controls on the distribution of neoselachian sharks and rays within the British Bathonian (Middle Jurassic). [PDF]

, 2003
Extensive sampling from a range of facies within the Bathonian (Middle Jurassic) of southern England has allowed the palaeoenvironmental distribution of a number of taxa of neoselachian sharks and rays to be assessed.

Oogenesis and germinal bed morphology of the brown anole (A. sagrei)

Developmental Dynamics, EarlyView.
Abstract Background The brown anole is a model species of the genus Anolis, a squamate (encompassing lizards and snakes) group widely studied in evolutionary, behavioral, and developmental biology. Full genome annotation, the establishment of gene editing techniques, and comprehensive description of reproductive tract morphology and embryogenesis in ...
