分析表型和外部因素对家庭范围区域的同时影响.
利用大规模的生态数据来理解复杂的动物行为.

主要方法:

利用了10年的捕获-重新捕获数据,对来自北美36个NEON地点的个别识别的鹿鼠进行了分析.
采用了强大的统计框架来分析一个大样本大小 (N=2,420个人).
研究了性别,身体状况,动物密度,息地类型和度对空间使用的相互作用影响.

主要成果:

证实雄性比雌性具有更大的家庭范围.
观察到随着动物密度的增加,家庭范围面积的减少.
确定身体状况和家庭范围区域之间的关系在性别之间有所不同.
在影响空间使用方面,发现了息地类型,度和动物密度之间的显著相互作用.

结论:

像NEON这样的大型生态网络对于解决以前仅限于样本大小的复杂行为问题是有价值的.
鹿鼠的空间使用是个体特征和环境因素之间的复杂相互作用的结果.
这些发现提升了我们对空间生态和动物行为驱动因素的理解.

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.

Ecological Niches

Ecological Niches

All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.

Threats to Biodiversity

Threats to Biodiversity

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...

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.
