概括

抗凝固 rodenticides (ARs) 在渔民 (Pekania pennanti) 中普遍存在,每年暴露量增加. 成年男性暴露率更高,受种子生产和人类密度等因素的影响.

科学领域:

野生动物毒理学
生态生态学生态生态学
保护生物学保护生物学

背景情况:

抗凝固 rodenticides (ARs) 通过二次中毒对非目标野生动物,特别是野生食肉动物构成风险.
暴露往往与城市附近有关,但农村AR使用也会导致二次暴露,其来源难以确定.
像杆播种这样的脉冲资源可以影响小哺乳动物种群,可能会影响渔民等捕食者的AR暴露.

研究的目的:

为了调查纽约州渔民 (Pekania pennanti) 对抗凝血剂杀剂 (AR) 暴露的模式.
为了确定生态因素 (杆播种) 和渔民特征 (年龄,性别) 是否影响AR暴露.
评估这种脆弱物种对AR暴露的时间趋势.

主要方法:

在森林覆盖梯度 (2018-2020年) 上,合法捕捞的渔民 (n=338) 中量化AR化合物.
基于渔民的性别,年龄和空间共变量的模型AR化合物检测概率和总数.
评估了木种子生产对麦醇暴露的影响.

主要成果:

83%的渔民检测到1-5个AR化合物;每年约8%的暴露增加.
成年渔民 (3-4岁) 和男性的暴露率最高.
增加前一年的种子生产与更高的布罗马迪奥隆暴露率相关.

结论:

在渔民中,AR暴露很普遍,而且在增加,这表明环境污染广泛.
渔民的年龄和性别,以及像杆播种这样的生态因素,影响AR暴露风险.
了解AR使用模式及其生态相互作用对于减轻野生动物暴露至关重要.

Predator-Prey Interactions

Predator-Prey Interactions

Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.

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.

Mutation, Gene Flow, and Genetic Drift

Mutation, Gene Flow, and Genetic Drift

In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).
