All species of crocodilians are long-lived, top-level carnivores that are integral components of aquatic, wetland, and marine/estuarine ecosystems. However, they are often excluded from studies on environmental contamination and ecological risk assessments.

Are Seeds Consumed by Crocodilians Viable? A Test of the Crocodilian Saurochory Hypothesis
Southeastern Naturalist, 2014Abstract Many animal species are important dispersers of seeds; however, relatively little attention has been paid to the seed-dispersal capabilities of reptiles, and almost nothing is known about the seed-dispersal capabilities of crocodilians. This lack of information is surprising given that seeds have been found in the stomach contents of a ...

Respiratory patterns in crocodilian reptiles
Respiration Physiology, 1970Abstract This paper describes the typical respiratory pattern of caimans and alligators and shows the great range of respiratory activity even in quiet, isolated caimans, with average ventilatory periods varying from 6–22 sec in length and consisting of an average of from 1–5 breaths, and nonventilatory periods averaging from 13 sec-3 min in length ...

OSMOREGULATION IN CROCODILIANS
Biological Reviews, 1988Summary1. The osmoregulatory strategies of crocodilians in both saline and fresh‐water environments are discussed and dissected into their separate components.2. Contrasts between members of the Alligatoridae and the Crocodylinae emerge repeatedly in aspects such as integumental permeabilities, functioning of the renal/cloacal system, and the presence ...

Flow dynamics of the crocodilian heart
American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 1989We report for the first time the flow events corresponding to the pressure patterns in the left and right aorta (LAo and RAo) during the cardiac cycle in the caiman (Caiman crocodylus ssp). These experiments show a complex LAo flow pattern; an initial small anterograde flow in the early systole is reversed to a backflow at midsystole.

Crocodilians are a ubiquitous component of the vertebrate fauna of the Wealden Supergroup of southern England. In the past 160 years, 11 species belonging to as many as nine genera have been recognized. Many of these taxa are represented by well-preserved specimens, often comprising complete skulls and articulated or associated postcranial skeletons ...

Sinusoidal daily and seasonal patterns of change in body temperature (Tb) measured at 15 degrees S latitude in 30-1,000 kg Crocodylus porosus are explicable by comparatively simple mathematical equations into which are fed only behaviour pattern, environmental data and body mass. This confirms that C.

Advancements in genomic techniques have greatly increased the scope of research into many aspects of crocodilian evolution and biology. As cold-blooded amniotes, crocodilians hold a unique evolutionary position for understanding all vertebrate lineages. Applying up-to-date genomic techniques to crocodilian genomes can have far-reaching implications for

A Formulary for Lizards, Snakes, and Crocodilians
Veterinary Clinics of North America: Exotic Animal Practice, 2000A formulary of drug dosages for use in lizards, snakes, and crocodilians based primarily on a survey of the existing literature is provided. The formulary is presented as a series of four tables: antimicrobial drugs; parasiticide drugs; anesthetic and analgesic drugs; and miscellaneous drugs. An extensive bibliography is included.
