概括

夏威夷乌的保护繁殖 (

科学领域:

* 鸟类保护生物学和野生动物管理.
* 危物种的繁殖生物学和行为生态学.

背景情况:

* 'Alalā (Corvus hawaiiensis),或夏威夷乌,在野外已经灭绝,仅通过保护繁殖计划才能持续存在.
* 传统的,动手的养殖方法虽然在繁殖方面是成功的,但可能不能完全支持对重新引入至关重要的自然行为的发展.
* 保持基本的自然行为对于重新引入和野生种群恢复的长期成功至关重要.

研究的目的:

* 适应现有的阿拉拉养殖技术,以培养自然繁殖行为.
* 为了增强对的结合,筑巢,卵和父母在囚禁环境中的照顾.
* 开发数据驱动的方法来评估繁殖成功和选择重新引入的候选人.

主要方法:

* 实施全职社会化,以加强伴侣关系.
* 促进自然筑巢,鼓励雌性化.
* 提供机会,以自然的父母抚养后代.
*使用标准化,数据驱动的跟踪来监控进展并评估释放候选人.

主要成果:

* 养殖中的适应正在使'阿拉拉夫妇能够表现出更自然的繁殖行为,包括更强的配对纽带和改进的筑巢.
*鼓励自然化和家长照顾正在取得进展,为幼鸟提供必要的养殖经验.
* 开发客观的,数据驱动的评估工具,可以更明智地选择重引入的鸟类.

结论:

* 修改后的养殖技术对于准备养的危物种至关重要,比如'Alalā,以成功重新引入.
*在保护育种计划中关注自然行为可以提高释放后生存和繁殖的可能性.
* 描述的方法和数据驱动方法可以为其他物种的保护,繁殖和重新引入努力提供信息和改进.

Conservation of Declining Populations

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.

Conservation of Small Populations

Conservation of Small Populations

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...

Optimal Foraging

Optimal Foraging

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.

What is Conservation Biology?

What is Conservation Biology?

Conservation biology is a scientific field that focuses on the preservation of biodiversity in order to protect ecosystems while meeting the needs of the human population. Humans require properly functioning ecosystems to maintain our supply of natural resources, including food, medicines, and building materials.

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.

Adaptations that Reduce Water Loss

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
