Ecological Niches02:02

Ecological Niches

25.8K
All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.

Conservation of Small Populations02:04

Conservation of Small Populations

16.5K
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...

Conservation of Declining Populations

12.4K
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.

What is Conservation Biology?

23.9K
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.

Threats to Biodiversity01:50

Threats to Biodiversity

26.3K
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...

Keystone Species01:39

Keystone Species

24.0K
Measures of species biodiversity, such as richness (i.e., the number of species present) and evenness (i.e., their relative abundance), describe an ecological community’s structure. Many factors affect community structure, including abiotic factors (e.g., sunlight and nutrients), disturbances (e.g., fire or flood), species interactions (e.g., predation or competition), and chance events (e.g., foreign species invasion). Certain species—such as keystone species—also play a...

科学分野:

  • エコロジー
  • 保護生物学
  • 環境科学

背景:

  • 種は前例のない環境変化に直面し 生き残るための適応能力が必要です
  • 保護された地域は 種の適応能力を保全するために 極めて重要です
  • 保護区を拡大する際には 環境の多様性を無視することが多い.

研究 の 目的:

  • 脊椎動物種の保護区域内の環境条件の表現を評価する.
  • 両生類,鳥類,陸上の哺乳類におけるニッチ表現の不十分な範囲を特定する.
  • 世界的な保全目標を達成するために,ニッチの代表性の重要性を強調します.

主な方法:

  • 世界的に19937種の脊椎動物の保護地域を分析した.
  • 種々の生息地における環境条件を評価することで,ニッチを定量的に表現する.
  • 保護区を拡大して環境のギャップを埋めるための土地面積のモデル化

主要な成果:

  • 研究された両生類,鳥類,陸上の哺乳類の90%以上にはニッチの表現が不十分である.
  • 環境のギャップを埋めるために保護区を拡大するには,現在の目標を上回る世界の土地面の33.8%が必要になります.
  • 生物多様性のホットスポットであるコロンビア,パプア・ニューギニア,南アフリカ,中国など

結論:

  • 保護区の拡大における環境条件 (ニッチ表現) を明示的に考慮することは,種の適応能力を維持するために不可欠です.
  • ニッチ表現を考慮しないことは,種の大部分の不十分な保護を危険にさらします.
  • 政策立案者は,将来の目標にニッチの代表を統合することによって,保全結果を改善する重要な機会を持っています.
