野生动物学报, 2014 为了解圈养白犀牛的血液生化指标,试验以7头不同年龄、性别的云南石林圈养白犀牛为研究对象,分别检测其17项血液生化指标,采用SPSS软件对检测数据进行比较。结果显示公母白犀牛血液生化指标中除尿酸(UA)差异极显著外,其余指标均不显著; 未成年体和成年体白犀牛血液生化指标中除钙(Ca)差异显著外,其余指标均不显著; 对比克鲁格国家公园放养方式的白犀牛血液生化指标数据参数,发现白蛋白(ALB)、尿素氮(BUN)、天门冬氨酸氨基转移酶(AST)和碱性磷酸酯酶(ALP)均表现为圈养状态显著(ALB,P=0.021;

Study on the inhibition to tyrosinase in Xinjiang plants [PDF]
, 2015 酪氨酸酶广泛存在于微生物，动植物及人体中，是一种多亚基的含铜的氧化还原酶。酪氨酸酶是合成黑色素的重要酶类，通过改变酪氨酸酶的活性可以控制黑色素生成量，从而对生物体内黑色素水平及相关代谢途径产生影响。 本文以新疆植物为研究对象，从新疆植物中提取了一批对蘑菇酪氨酸酶具有抑制作用的天然活性物质。多种植物都是首次研究，还没有文献报道。在理论上从酶学角度系统阐述了天然活性物质与蘑菇酪氨酸酶的作用机理及其生物活性。 本文经过粗提的植物，再经石油醚，乙酸乙酯，氯仿，正丁醇萃取，得到不同提取层的物质 ...

Functional Ecology, Volume 40, Issue 4, Page 800-815, April 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Studies have shown that organisms may adjust metabolic rates in response to thermal variability, highlighting metabolic plasticity as a key adaptive mechanism. Understanding the extent of metabolic plasticity of an organism is key to predicting its adaptation to climate

Lessons learned from screening potential other effective area‐based conservation measures
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Other effective area‐based conservation measures (OECMs) are sites that deliver effective biodiversity outcomes irrespective of their management objectives. These areas are widely expected to play an important role in efforts to protect 30% of Earth by 2030.
