概括
现代GPS项圈对野马和子的福利风险最小,对生存或身体状况没有重大影响. 观察到轻微的皮毛和皮肤影响,但在适当的监测下,项圈被认为是生态研究的安全.
科学领域:
- 野生动物生态生态学
- 动物福利科学 动物福利科学
- 保护技术 保护技术
背景情况:
- 野马 (Equus caballus) 和公牛 (E. asinus) 居住在北美牧场,但它们的细微空间生态不太了解.
- 全球定位系统 (GPS) 追踪项圈是研究马匹空间使用的宝贵工具,但较旧的设计存在福利问题.
- 现代GPS项圈设计需要对自由漫游的马匹的潜在福利风险进行评估.
研究的目的:
- 评估现代GPS项圈对自由游荡的马和驴的福利影响.
- 评估GPS项圈对马匹生存,身体状况和行为的影响.
- 为了确定GPS项圈在野马使用的长期影响和物理后果.
主要方法:
- 在美国西部的5个种群中,GPS项圈被安装在105匹马和60头驴上,持续了4年.
- 我们比较了带领和没有领的马匹及其后代的生存率.
- 项圈适合,毛皮效应,皮肤擦伤,身体状况和行为都被监测和记录.
主要成果:
- 没有发现有领和没有领的马和burros或他们的小马之间生存的显著差异.
- 观察到轻微的皮肤效应 (3%的马,25%的) 和肤浅的皮肤效应 (2%的马,11%的),没有严重的结果.
- 项圈对身体状况和行为的影响很小,尽管注意到一些暂时的姿势和食变化.
结论:
- 现代GPS项圈是研究自由漫游的马匹福利和空间生态学的安全和生物学上微不足道的工具.
- 定期监测和使用远程/定时释放机制对于减轻潜在风险至关重要.
- 拼接可以有效地用于提高对马群,息地使用和物种间相互作用的理解.

Migration
8.1K
Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.

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...

Conservation of Small Populations
14.4K
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...

Limits to Natural Selection
30.0K
Organisms that are well-adapted to their environment are more likely to survive and reproduce. However, natural selection does not lead to perfectly adapted organisms. Several factors constrain natural selection.

Habitat Fragmentation
15.8K
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.
