Optimal Foraging00:48

Optimal Foraging

13.5K
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.

Convergent Evolution01:54

Convergent Evolution

31.3K
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

Predator-Prey Interactions02:39

Predator-Prey Interactions

21.0K
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.

Production Efficiency01:01

Production Efficiency

18.1K
Net production efficiency (NPE) is the efficiency at which organisms assimilate energy into biomass for the next trophic level. Due to low metabolic rates and less energy spent on thermoregulatory processes, the NPE of ectotherms (cold-blooded animals) is 10 times higher than endotherms (warm-blooded animals).

Epiphytes, Parasites, and Carnivores02:40

Epiphytes, Parasites, and Carnivores

16.5K
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...

Conservation of Small Populations02:04

Conservation of Small Populations

16.6K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

科学领域:

  • 生态生态学 生态生态学
  • 动物行为 动物行为
  • 捕食者和猎物的动力学

背景情况:

  • 大型捕食者通常以高成本和失败率狩猎大型猎物,而小型捕食者则高效地狩猎小型,丰富的猎物.
  • 大多数蝙蝠都是以昆虫为食的小型捕食者,但有些物种表现出真正的肉食性,狩猎更大的脊椎动物猎物.
  • 在小蝙蝠中,这种食肉策略呈现出一种悖论,原因是高代谢需求和与狩猎大型稀缺猎物相关的能量成本.

研究的目的:

  • 为了研究食肉类边唇蝙蝠 (Trachops cirrhosus) 准大型脊椎动物猎物的狩猎行为和精力充的策略.
  • 解决这样一个悖论:具有高新陈代谢率的小蝙蝠如何维持一个涉及大,少量猎物的狩猎策略.

主要方法:

  • 使用声音和运动生物识别标签量化了20只野生边唇蝙蝠的狩猎行为.
  • 估计的猎物大小相对于蝙蝠的体重,并分析了狩猎成功率和飞行时间.
  • 观察到的猎物捕获和消费,包括时间.

主要成果:

  • 边唇蝙蝠捕猎的猎物大约占其体质的7%,并有可能捕捉到其自身大小的猎物.
  • 蝙蝠表现出极高的狩猎效率,平均只花费11%的夜晚在飞行中.
  • 通过偷听猎物声音和埋伏掠食,实现了高狩猎成功率 (中位数为50%),这表明低风险/高收益策略.

结论:

  • 肉食蝙蝠采用专门的,高效的狩猎策略,与典型的捕食者-猎物动态形成鲜明对比.
  • 这种低风险/高收益策略取决于原始息地的高猎物密度.
  • 由于息地变化,这种掠夺性行为的专门性质引发了人们对这些蝙蝠在人类纪的长期生存的担忧.
