Integrative Conservation, Volume 4, Issue 2, Page 188-204, June 2025.We assessed the distribution of 14 threatened agamid lizard species using Species Distribution Modeling to identify hotspots for these species' conservation. Based on the results, high‐priority areas of threatened agamids were projected to occur specially in the wet zone.

Studies on the Preparation and Biological Activities of Chondroitin Sulfate from Crocodile [PDF]
, 2017 动物软骨组织中含有一种以蛋白聚糖形式存在的酸性粘多糖——硫酸软骨素，应用现代生物技术方法适当处理后，能获得优质的硫酸软骨素，同时获得良好的社会价值和经济效益。 本论文主要利用碱提取技术，以加工废弃的鳄鱼软骨为原料，通过选择合适的提取工艺流程，研究开发鳄鱼硫酸软骨素产品。通过研究碱提取过程中影响得率的单因素，并结合响应面分析得到最优提取条件为：NaOH浓度5%，固液比1:14g/mL，温度40℃、时间209.82min。采用离子交换色谱法对粗提物进一步纯化，根据峰形确定得到单一物质；通过化学组成测定 ...

Properties of Physical and Chemistry of Crocodile Peptide and effects on Biological Process [PDF]
, 2012 本论文通过3种蛋白酶酶解鳄鱼肉的产物比较、成分分析和生理功能研究，开发鳄鱼多肽保健品。 分别用菠萝蛋白酶、胰蛋白酶以及中性蛋白酶对鳄鱼肉进行酶解处理，以酶解产物中的游离氨基酸含量的多寡即降解度为标准探讨了酶解的最佳条件，包括水解时间、酶量、温度等，结果表明，采用胰蛋白酶酶解较为理想，酶解时间为4h，酶量为0.4%较为合理。将酶解处理液通过离心，去除不溶的杂质，取上清，喷雾干燥，得到的鳄鱼活性多肽粉为白色粉末，得率为10.5%（100g鲜肉得到10.5g干粉），显著高于文蛤肉粉的得率6.5 ...

Scale of unregulated international trade in Australian reptiles and amphibians
Conservation Biology, Volume 38, Issue 5, October 2024.Abstract Reptiles and amphibians are popular in the exotic pet trade, where Australian species are valued for their rarity and uniqueness. Despite a near‐complete ban on the export of Australian wildlife, smuggling and subsequent international trade frequently occur in an unregulated and unmonitored manner.
