Viruses, 2022 The risk of flavivirus infections among the crocodilian species was not recognised until West Nile virus (WNV) was introduced into the Americas. The first outbreaks caused death and substantial economic losses in the alligator farming industry.

Genome Biology and Evolution, 2018 The epidermis of amniotes forms a protective barrier against the environment and the differentiation program of keratinocytes, the main cell type in the epidermis, has undergone specific alterations in the course of adaptation of amniotes to a broad ...

The Anatomical Record, EarlyView.Abstract In birds, the neural canal houses a variety of anatomical structures including the spinal cord, meninges, spinal vasculature, and respiratory diverticula. Among these, paramedullary diverticula and the extradural dorsal spinal vein may leave behind osteological correlates in the form of pneumatic foramina and fossae, and a bilobed geometry of ...

The Anatomical Record, EarlyView.Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...

3D anatomical atlas of the heads of male and female adult Chamaeleo calyptratus
The Anatomical Record, EarlyView.The veiled chameleon is a model organism in reptile development research. Utilizing contrast‐enhanced microCT and deep learning segmentation models, we have generated the first digital atlases of the skull, nervous system, cranial muscles and hyolingual muscles.

Scientific Reports, 2018 The trophic position of a top predator, synonymous with food-chain length, is one of the most fundamental attributes of ecosystems. Stable isotope ratios of nitrogen (δ15N) have been used to estimate trophic position of organisms due to the predictable ...

, 2009 This chapter presents a general overview of the anatomy, physiology, and treatment methodology for crocodilians. Most crocodilians grow to be larger than other reptile species and, therefore, have significant space requirements. Like most animals requiring an aquatic environment, crocodilians need water that is clean and free of disease.

Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs
The Anatomical Record, EarlyView.Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

Agonistic behaviours displayed by young crocodilians.
, 2013 Postures, non-contact and contact movements (described in Table 3) displayed by hatchling (h) and juvenile (j) crocodilians. Crocodilians in the figure include G. gangeticus - h (a); P. palpebrosus (b); C. siamensis; (c); C.
