Abstract:

The Philippine crocodile (Crocodylus mindorensis) is considered one of the most endangered of the crocodilian species.Rumors or anecdotal concerns have existed for some time as to the possibility of hybrid individuals existing in a captivecollection under consideration for providing reintroduction candidates; however, visual observations failed to identify sus-pected hybrids. Samples were collected from 619 Philippine crocodiles from several captive facilities and two free-rang-ing populations. Mitochondrial DNA D-loop (601 bp) fragments were sequenced for each crocodile and compared to 28indi

AbstractThe catalytic activity of phospholipase A2 (PLA2) was measured in serum samples from 32 crocodiles in Thailand and Australia by a method using 14C-oleic acid-labelled autoclaved Escherichia coli membranes as a substrate. The highest PLA2 activity was measured in the serum of Crocodylus siamensis (n = 9, mean ± SD), 13.3 ± 3.1 U/l followed by hybrid C. siamensis × C. porosus (n = 6), 10.4 ± 8.7 U/l and Crocodylus porosus (n = 17), 4.3 ± 3.0 U/l. The difference between C. siamensis and C. porosus was highly significant (P < 0.001). The gender of the animals and the geographical locati

Abstract:

The aim of the present study was to develop a protocol for the successful cryopreservation of Saltwater crocodile spermatozoa. Sperm cells were frozen above liquid nitrogen vapour in phosphate-buffered saline (PBS) containing either 0.3 M trehalose, 0.3 M raffinose or 0.3 M sucrose and compared with glycerol (0.3–2.7 M). Although the highest levels of mean post-thaw motility were observed following cryopreservation in 0.3 M trehalose (7.6%) and 0.3 M sucrose (7.3%), plasma membrane integrity (PI) was best following cryopreservation in 2.7 M glycerol (52.5%). A pilot study then assessed the cyt

Abstract:

A total of 6444 Crocodylus porosus (4303 non-hatchlings and 2141 hatchlings) were recorded during 196 vessel-based surveys of 103 waterways to determine the distribution and abundance of Crocodylus porosus in Queensland. The surveys, conducted from January 1994 to December 2000, covered 4174.3 km of waterway. Population structure was biased towards immature crocodiles, with 91% of all animals sighted being less than the minimum breeding size for individuals in the Northern Territory. The mean relative density of non-hatchling C. porosus was highest in waterways of north-western Cape York Penin

Abstract:

We examined agonistic behaviour in hatchling Australian freshwater crocodiles (Crocodylus johnstoni) at 2 weeks, 13 weeks, and 50 weeks after hatching, and between C. johnstoni and saltwater crocodiles (Crocodylus porosus) at 40–50 weeks of age. Among C. johnstoni, agonistic interactions (15–23 s duration) were well established by two weeks old and typically involved two and occasionally three individuals, mostly between 17 : 00 and 24 : 00 hours in open-water areas of enclosures. A range of discrete postures, non-contact and contact movements are described. The head is rarely targeted in cont

Abstract:

The emetic (vomiting) reflex in a crocodilian, Crocodylus porosus, was characterised for the first time using the plant alkaloid veratrine (5 mg kg(−)(1) i.v. or i.p.) as an emetic stimulus. The latency to the onset of vomiting was 8.0+/−0.9 min (mean +/− s.e.m., N=5 animals). Vomiting was preceded by a clearly defined set of prodromal behaviours including, in temporal sequence, rhythmic contraction of the pharynx, sneezing and jaw snapping. Expulsion of vomitus was not particularly forceful and was accompanied by lateral shaking of the head. Physiological studies revealed that vomiting was ac

Abstract:

BackgroundCancer remains a global threat resulting in significant morbidity and mortality despite advances in therapeutic interventions, suggesting urgency for identification of anticancer agents. Crocodiles thrive in polluted habitat, feed on germ-infested meat, are exposed to carcinogenic heavy metals, are the very few species to survive the catastrophic Cretaceous–Paleogene extinction event, yet have a prolonged lifespan and rarely been reported to develop cancer. Therefore, we hypothesised that animals living in polluted environments such as crocodiles possess anticancer molecules/mechanis

Abstract:

This study documented details of the dentitions, skulls and other skeletal remains of Crocodylus porosus and Tomistoma schlegelii, from western part of Sarawak, Malaysian Borneo. The remains of both reptiles were exhumed, followed by standard cleaning procedures and then detail morphological assessments were carried out accordingly. Both species show similar structure of vertebral columns, but T. schlegelii has the following unique structures: a long and narrower snout, D-shaped eye sockets, long and sharp pointed protruding quadratojugal bones, straight maxillae and dentary, a smooth surfaced

Abstract:

The project sought to examine the effects of habitat loss and fragmentation on the ecology and population genetics of the estuarine crocodile (Crocodylus porosus). Additionally, the role played by humans in this anthropogenically-altered landscape was examined. Through the utilisation of a host of technologies, some previously established, some completely novel in crocodilian research, a new insight into how the landscape is utilised by these cryptic predators was developed. This project represents a first detailed look at Sabah’s crocodilian population, as well as being the first active croco
