概括
在不稳定的宿舍中冬眠的三色蝙蝠表现出较短的睡期,受到天气的影响. 这可能会降低它们对白鼻综合征 (WNS) 的易感性,与稳定息的蝙蝠不同.
科学领域:
- 生态生态学 生态生态学
- 动物学 动物学
- 野生动物生物学 野生动物生物学
背景情况:
- 白鼻综合症 (WNS) 导致冬眠蝙蝠的数量显著下降,特别是那些在稳定的地下环境中息的蝙蝠.
- 一些蝙蝠种类利用热不稳定的宿舍,如桥梁和空洞,这可能会影响它们的过冬生理学和易受WNS的影响.
研究的目的:
- 为了研究三色蝙蝠 (Perimyotis subflavus) 在热不稳定的中冬季的模式.
- 为了确定环境天气条件和息特征如何影响蝙蝠和冬眠期间的活动.
- 评估这些模式对该物种WNS易感性的潜在影响.
主要方法:
- 从11月到3月 (2017-2019) 在南卡罗来纳州的三色蝙蝠上部署温度敏感发射器.
- 在桥梁和可访问的空洞中监测室温度,记录每日和最大波动.
- 分析的持续时间,唤醒模式和活动水平与环境温度,降水和气压相关的情况.
主要成果:
- 在热不稳定的宿舍中,三色蝙蝠的平均昏迷持续时间为2.7天,与环境温度负相关.
- 活动模式,包括正常热的攻击时间和远离的活动,与环境温度有积极的关系.
- 蝙蝠表现出非随机的兴奋模式,51%的兴奋涉及被动回暖,并在33.6%的追踪日内活跃.
结论:
- 环境天气条件显著影响居住在热不稳定的宿舍的三色蝙蝠的冬季的模式.
- 在不稳定的子中,较短的麻木期和潜在的冬季食与稳定的子的行为形成鲜明对比,这表明WNS易感性可能较低.
- 了解宿舍的热稳定性对于评估广泛分布的冬眠蝙蝠物种的生理灵活性和WNS风险至关重要.

Conservation of Declining Populations
9.5K
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.

Predator-Prey Interactions
15.9K
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
17.3K
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.

Threats to Biodiversity
21.9K
There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...

Decreased Body Temperature
578
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...
