Environmental resistance and habitat quality influence dispersal of the saltwater crocodile. [PDF]

Mol Ecol, 2022
AbstractLandscape genetics commonly focuses on the effects of environmental resistance on animal dispersal patterns, but there is an emerging focus on testing environmental effects on emigration and settlement choices. In this study, we used landscape genetics approaches to quantify dispersal patterns in the world's largest crocodilian, the saltwater ...

Epidermal scale growth, allometry and function in non-avian dinosaurs and extant reptiles. [PDF]

J Anat
Scale shapes in non‐avian dinosaurs and extant reptiles are mostly retained through growth. However, positive scale allometry and proportional differences in scale breadth are also detected, which are likely associated with changing body proportions. Based on their generally conserved morphology and impracticality for visual display, the enlarged size ...

Crocodile defensin (CpoBD13) antifungal activity via pH-dependent phospholipid targeting and membrane disruption

Nature Communications, 2023
Defensins are a class of host defence peptides that contribute to the immune system of eukaryotes. Here, the authors report the structure of saltwater crocodile defensin CpoBD13 and the mechanism of pH-dependent antifungal activity.

Analysis of Microsatellites and Parentage Testing in Saltwater Crocodiles [PDF]

Journal of Heredity, 2004
Fifteen microsatellite loci were evaluated in farmed saltwater crocodiles for use in parentage testing. One marker (C391) could not be amplied. For the remaining 14, the number of alleles per locus ranged from two to 16, and the observed heterozygosities ranged from 0.219 to 0.875. The cumulative exclusion probability for all 14 loci was .9988.

Glucocorticoids, thyroid hormones, and iodothyronine deiodinases in embryonic saltwater crocodiles [PDF]

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 2002
We investigated the relationship between glucocorticoids, thyroid hormones, and outer ring and inner ring deiodinases (ORD and IRD) during embryonic development in the saltwater crocodile ( Crocodylus porosus). We treated the embryos with the synthetic glucocorticoid dexamethasone (Dex), 3,3′,5-triiodothyronine (T3), and a combination of these two ...

Agonistic behavior of captive saltwater crocodile, crocodylus porosus in Kota Tinggi, Johor [PDF]

, 2021
Agonistic behavior in Crocodylus porosus is well known in the wild, but the available data regarding this behavior among the captive individuals especially in a farm setting is rather limited. Studying the aggressive behavior of C.

A new species of Chlamydia isolated from Siamese crocodiles (Crocodylus siamensis).

PLoS ONE, 2021
Chlamydia is a known pathogen in both saltwater and freshwater crocodiles. However, the exact species/strain has not been clearly identified. In this study, we successfully cultivated Siamese crocodile Chlamydia in McCoy cells at a temperature of 30°C ...
