- 保護生物学の保護生物学
背景:
- 大型古い木 (LOT) は,生態学的に,美学的に,そして歴史的に重要な生きた記念碑です.
- LOTの多様性,分布,保全状態を理解することは,標的型保護に不可欠です.
- 以前は,中国の広西省のLOTの包括的な分析が欠けていました.
研究 の 目的:
- 広西のLOT (>500年) の分類,種多様性,空間分布,保全状態を評価する.
- 異なる都市や農村の景観でLOTの分布と健康状態のパターンを特定する.
- 地域のLOTの統合保全戦略を参考にすること.
主な方法:
- 公に公開されている政府データとフィールド調査を利用した.
- カタログ化されたLOTは,分類,種,および数によって分類されています.
- 空間分布パターンを分析し,様々な土地使用形態における木の健康状態を評価した.
主要な成果:
- 広西では,149の種,105の属,48のファミリーにわたる2,630のLOTを特定しました.
- LOTの豊かさと多様性の緯度グラデントが観察され,低緯度に向かって減少しています.

Conservation of Declining Populations
13.4K
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
17.5K
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...

Threats to Biodiversity
27.2K
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...

What is Conservation Biology?
24.5K
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.

Adaptations that Reduce Water Loss
28.3K
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.

Habitat Fragmentation
21.5K
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.
