概括

弹药带来了环境风险. 塔斯马尼亚魔鬼在屠宰场附近的暴露量略有增加,一些个体暴露在弹药中,尽管大多数暴露来源尚不清楚.

科学领域:

环境科学环境科学
野生动物毒理学野生动物毒理学
保护生物学保护生物学

背景情况:

基于的弹药是环境中主要的来源,影响野生动物,特别是食尸动物.
虽然已知鸟类食尸动物的影响,但哺乳动物食尸动物对暴露的反应需要进一步调查.

研究的目的:

评估塔斯马尼亚魔鬼 (Sarcophilus harrisii) 的暴露,这是一个专门的哺乳动物食者.
为了确定使用弹药的袋鼠杀计划是否增加了魔鬼的暴露.
通过将魔鬼血中的同位素特征与杀伤弹药进行比较来识别来源.

主要方法:

血水平 (BLLs) 在23只屠宰前和15只屠宰后的魔鬼中进行了分析.
线性混合效应模型用于分析BLLs.
恶魔血中的同位素标志与杀弹药样本进行了比较.

主要成果:

在屠宰前和屠宰后,平均BLL没有发现显著差异.
屠宰场附近的魔鬼有更高的BLL,在屠宰后的33%的水平升高,而在屠宰前的18%.
一个恶魔显示出与弹药相匹配的同位素签名,表明在被杀的尸体上进行了清理;大多数样本表明其他来源.

结论:

虽然一些塔斯马尼亚魔鬼可能会清理射尸体,但在研究区域的大多数没有显示最近显著的暴露从杀.
对于这个危物种来说,其他环境源可能是重要的.
即使是低水平也会影响临灭绝的塔斯马尼亚魔鬼的健康和免疫力.

Habitat Fragmentation

Habitat Fragmentation

Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.

Conservation of Declining Populations

Conservation of Declining Populations

Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.
