概括

农业做法对野生动物产生影响. 1990-2019年公民科学数据显示,无脊椎动物在高耕地地区的减少最多,这表明目前的管理不能支持生物多样性恢复.

科学领域:

生态生态学生态生态学
保护生物学保护生物学
农业科学农业科学

背景情况:

现代农业显著改变了景观,影响了野生动物种群.
农业政策和管理在过去的30年里不断发展,越来越重视可持续性.
了解对有益无脊椎动物的长期农业影响对于评估保护效率至关重要.

研究的目的:

分析1990年至2019年英国无脊椎动物占用率的趋势.
将这些趋势与不同耕地覆盖面 (没有,低,高) 的不同地区进行比较.
评估最近的农业政策和管理实践在支持无脊椎动物恢复方面的有效性.

主要方法:

利用大规模的公民科学数据集来追踪无脊椎动物占用率.
分析了30年 (1990-2019) 的趋势.
根据耕地覆盖面积的百分比分类的地区的无脊椎动物种群趋势进行比较.

主要成果:

在英国各地观察到无脊椎动物群体的总体下降.
无脊椎动物种群在耕地覆盖率高 (>50%) 的地区出现了最显著的下降.
这表明目前的耕地管理策略不足以保护无脊椎动物群落.

结论:

尽管政策转向可持续发展,但密集农业,特别是高耕地地区,对无脊椎动物的生物多样性产生了负面影响.
为了提高农业生态系统的弹性和可持续性,需要新的政策驱动力和激励措施.
英国脱欧后的农业政策变化为改革景观为生物多样性和社会利益提供了机会.

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...

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.

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.

What is Biodiversity?

What is Biodiversity?

Biodiversity describes the variety of living things at multiple organizational levels: genetic, species and ecosystem diversity. Species diversity includes all branches of the evolutionary tree from single-celled prokaryotic organisms, bacteria, and archaea, to the eukaryotic kingdoms: plants; animals; fungi; and protists. To date, there have been about 1.75 million species identified, and new species are discovered every week.

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.

Biodiversity and Human Values

Biodiversity and Human Values

Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.
