Gross and microanatomy of the male reproductive duct system of the saltwater crocodile Crocodylus porosus

Reproduction, Fertility and Development, 2021
Information on the morphology and histology of the male reproductive system of the Crocodylia species is necessary to determine the role of these tissues in the production of functional spermatozoa. Accordingly, in this study we examined the gross morphology and microanatomy of the testis and the male excurrent duct system through which spermatozoa ...

Characterisation of the intestinal microbiota of commercially farmed saltwater crocodiles, Crocodylus porosus

Applied Microbiology and Biotechnology, 2019
The Australian saltwater crocodile (Crocodylus porosus) industry began commercially in the 1980s, producing skins for export and crocodile meat as a by-product. Industry research has thus far focused on strategies to improve production efficiency.

Steroidogenic Enzyme Activity and Ovarian Differentiation in the Saltwater Crocodile, Crocodylus porosus

General and Comparative Endocrinology, 1994
It has been hypothesized that steroid hormone production is involved in sexual differentiation of the gonads in reptiles with temperature-dependent sex determination. We have therefore examined steroidogenic enzymes and ovarian differentiation in Crocodylus porosus embryos incubated at 30 degrees, a temperature producing 100% female hatchlings. delta 5-

253 Novel polymorphic microsatellites for the saltwater crocodile (Crocodylus porosus)

Conservation Genetics, 2008
Genomic elucidation and mapping of novel organisms requires the generation of large genetic resources. In this study, 253 novel and polymorphic microsatellite loci were isolated and characterized for the saltwater crocodile (Crocodylus porosus) by constructing libraries enriched for microsatellite DNA.

Crocodiles Farms and the Management of Saltwater Crocodiles in the Northern Territory: Results of a Survey of NT Crocodile Farmers plus Analysis of Secondary Information

2005
After outlining some relevant background information about the NT crocodile farming industry and explaining the purpose of our survey of NT crocodile farmers conducted in the first half of 2005, this paper reports the results of the survey. The information received from the survey is supplemented by secondary data and by information from secondary ...

Precious reptiles: Social engagement and placemaking with saltwater crocodiles

Area, 2018
In this paper I take up the call to expand the boundaries of social and physical landscapes in order to recognise the creative agencies of human and non‐human actors. In doing so, I wish to draw attention to the ways in which relations between both individuals and collectives combine to shape multi‐dimensional sociality in particular places.

Monitoring Saltwater Crocodiles (Crocodylus Porosus) in the Northern Territory of Australia

1992
Saltwater crocodiles (Crocodylus porosus) were protected in the Northern Territory in 1971, and a General Survey Program Based on spotlight counts was initiated 3 yr later. In the mid-1980s, monitoring needs were reviewed and rationalized. The current monitoring program operates at two levels of resolution. At a local population level, annual spotlight

MHC class I of saltwater crocodiles (Crocodylus porosus): polymorphism and balancing selection

Immunogenetics, 2012
Saltwater crocodiles are in high demand for the production of luxury fashion items. However, their susceptibility to disease incurs substantial losses and it is hoped to be able to genetically select these animals for disease resistance. So far, this has only been enabled by phenotypic selection. Investigating the major histocompatibility complex (MHC)

Characterisation, diversity and evolution of the saltwater crocodile MHC

2013
Abstract The saltwater crocodile (Crocodylus porosus) forms the basis of a crocodile farming industry for the international skin trade in Australia. For this industry, mortalities from stress and disease are common due to a compromise of the adaptive immunity.

Growth and survival of hatchling saltwater crocodiles (Crocodylus porosus) in captivity

2015
Agonistic and thermal behaviour was studied in hatchling Crocodylus porosus under captive conditions using CCTV cameras. The results guided the design of experiments aimed at improving growth and survival of this species in captivity. C. porosus are born with a repertoire of 16 distinctive agonistic behaviours, and most interactions occur in the ...
