概括
全球两动物采样不完整,在物种丰富的地区存在重大数据缺口. 自然保护区 (NPA) 和关键生物多样性区域 (KBA) 等保护区几乎没有覆盖这些未被采样的区域.
科学领域:
- 全球两动物的多样性和分布.
- 保护生物学和生物多样性评估.
- 地理信息系统 (GIS) 和空间分析.
背景情况:
- 两动物种群面临着全球变化的重大威胁.
- 准确的分布数据对于有效的保护计划至关重要.
- 目前两动物数据的完整性在生物地理领域之间有很大差异.
研究的目的:
- 在全球范围内评估两动物采样完整性.
- 评估采样完整性和保护区 (NPA和KBA) 之间的重叠.
- 确定两动物研究和保护的关键数据缺口区域.
主要方法:
- 在六个生物地理领域对两动物采样完整性的分析.
- 区域的分类为采样良好,采样不足和数据缺口类别.
- 采样类别和自然保护区 (NPA) 和关键生物多样性区域 (KBA) 之间的空间重叠分析.
主要成果:
- 近北极和澳大利亚的领域显示了最高的采样完整性.
- 在非洲热带,印度马来亚,新热带和古北极领域存在显著的数据缺口.
- 在样本不足/数据缺口区域和NPA/KBA之间发现的空间重叠率不到35%.
结论:
- 两动物分布数据在很大程度上是不完整的,特别是在物种丰富的热带地区.
- 现有的保护优先事项不充分覆盖了被采样不足的两生物息地.
- 迫切需要采取保护行动,以解决数据缺口并保护两动物的多样性.

Habitat Fragmentation
17.3K
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
9.5K
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.

Hybrid Zones
16.6K
Hybrid zones are narrow regions where two closely related species interact, mate, and produce hybrids. Relative to either parent species, hybrids may possess distinct phenotypic or genetic differences that impact their survival and reproductive success. The genetic variances introduced by hybridization influence species diversity and speciation processes within the hybrid zone.

What is Biodiversity?
26.9K
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.
