Optimal Foraging00:48

Optimal Foraging

12.0K
How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

Social Loafing01:37

Social Loafing

34.7K
Another way in which a group presence can affect performance is social loafing—the exertion of less effort by a person working together with a group. Social loafing occurs when our individual performance cannot be evaluated separately from the group. Thus, group performance declines on easy tasks (Karau & Williams, 1993). Essentially individual group members loaf and let other group members pick up the slack. Because each individual’s efforts cannot be evaluated,...

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.

Habitat Fragmentation02:31

Habitat Fragmentation

17.4K
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.

Epiphytes, Parasites, and Carnivores

12.9K
Plants often form mutualistic relationships with soil-dwelling fungi or bacteria to enhance their roots’ nutrient uptake ability. Root-colonizing fungi (e.g., mycorrhizae) increase a plant’s root surface area, which promotes nutrient absorption. While root-colonizing, nitrogen-fixing bacteria (e.g., rhizobia) convert atmospheric nitrogen (N2) into ammonia (NH3), making nitrogen available to plants for various biological functions. For example, nitrogen is essential for the...

Symbiosis00:58

Symbiosis

27.5K
Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...

悬崖 (Petrochelidon pyrrhonota) 在40年内显示社会食和信息传输减少. 这种转变可能会减少殖民巢的健康益处,原因是食策略和环境条件的变化.

  • 动物行为 动物行为
  • 保护生物学 保护生物学

背景情况:

  • 社会食增强了猎物的位置,特别是对于不可预测的资源.
  • 殖民性可以促进采集者之间的信息传输,提高养效率.
  • 环境变化对社会食和殖民利益的长期影响尚不清楚.

研究的目的:

  • 在40年的时间里调查悬崖的社会食,信息传输和食生态的变化.
  • 评估长期环境变化如何影响食策略以及殖民巢的优势.
  • 为了确定改变食行为对Cliff Swallow健身的后果.
