An Interim Method for Estimating the Age of Crocodylus porosus

Wildlife Research, 1983
On the basis of a reference series incubated at 30°C, methods for assigning unknown-aged embryos an approximate '30°C age' are derived. Determining real age is confounded by a paucity of information on the nest environment and its influence on embryonic development rate.

Abnormalities and Injuries in the Estuarine Crocodile Crocodylus Porosus.

Wildlife Research, 1977
Abnormalities and injuries in C, porosus are described, and their frequency in different size classes determined. There is no significant increase in injury frequency in size classes up to 70cm snoutvent length (SVL), which suggests that juvenile injuries are obtained soon after hatching. In size classes above 70cm SVL, injury frequency is high; 80% of

Impact of poxvirus lesions on saltwater crocodile (Crocodylus porosus) skins

Veterinary Microbiology, 2017
Cutaneous poxvirus infections are common in several crocodilian species and are of importance in crocodile farming due to their potential impact on the tanned hide. To confirm poxvirus infection and understand the impact on saltwater crocodile (Crocodylus porosus) skin, fourteen animals from different age groups (five hatchlings, five yearlings and ...

The assessment of sperm DNA fragmentation in the saltwater crocodile (Crocodylus porosus)

Reproduction, Fertility and Development, 2017
Herein we report a method of assessing DNA fragmentation in the saltwater crocodile using the sperm chromatin dispersion test (SCDt) after including frozen–thawed spermatozoa in a microgel (Halomax; Halotech DNA, Madrid, Spain). Following controlled protein depletion, which included a reducing agent, sperm nuclei with fragmented DNA showed a ...

Gut blood flow in the estuarine crocodile,Crocodylus porosus

Acta Physiologica Scandinavica, 1991
Simultaneous recordings of blood flow in the right and left aorta and carotid and coeliac artery were made in the crocodile,Crocodylus porosusat rest and during various stimuli. In resting animals the right aorta and carotid artery flow profiles resembled the recordings obtained in the caiman (Axelssonet al.

Scaling of standard metabolic rate in estuarine crocodiles Crocodylus porosus

Journal of Comparative Physiology B, 2012
Standard metabolic rate (SMR, ml O2 min(-1)) of captive Crocodylus porosus at 30 °C scales with body mass (kg) according to the equation, SMR = 1.01 M(0.829), in animals ranging in body mass of 3.3 orders of magnitude (0.19-389 kg). The exponent is significantly higher than 0.75, so does not conform to quarter-power scaling theory, but rather is likely

Digestion, assimilation and metabolism of captive estuarine crocodiles, Crocodylus porosus

Comparative Biochemistry and Physiology Part A: Physiology, 1988
1. Digestion, assimilation and metabolism of lean and fatty pork were studied in immature C. porosus. 2. Up to 92% of protein was digested but protein digestion was adversely affected by high levels of dietary fat. 3. Protein was catabolized in preference to fat, much of which was stored, although the ratio between metabolizable energy and protein ...

Thermoregulation in crocodilians—II. A telemetric study of body temperature in the Australian crocodiles, Crocodylus johnstoni and Crocodylus porosus

Comparative Biochemistry and Physiology Part A: Physiology, 1976
Abstract 1. Body temperature of Crocodylus johnstoni and C. porosus were recorded using radio telemetry. 2. Mean preferred temperature ranges were similar for both species, but those of C. johnstoni (31·3-32·5°C) were slightly lower than those found of C. porosus (32·0–33·1°C). 3. Little variation occurred in the mean daily body temperature.

Status of the Crocodile (Crocodylus porosus, Schneider) Industry in the Philippines

Transactions of the National Academy of Science and Technology, 2013
Crocodiles in the Philippines are listed in the Appendix 1 of the Conservation on International Trade of Endangered Species of Wild Fauna and Flora (CITES). But based on the wide distribution of the Crocodylus porosus, a closed-cycle breeding for commercial trade is permitted though the Crocodylus mindorensis is for conservation.

Crocodylus johnstoni and C. porosus Coexisting in a Tidal River

Wildlife Research, 1983
A 52.5-km section of the Adelaide River, N.T. (12°13'S., 131°13'E.). was spotlight-surveyed 20 times between June 1979 and September 1981. C, johnstoni (15.3 ± 9.2 sighted per survey) were less abundant than C. porosus (137.6 ± 36.5 sighted per survey), and were mainly in the upstream 20 km of the survey route (96% of C.
