Threats to Biodiversity

26.4K
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...

Trophic Efficiency00:46

Trophic Efficiency

24.9K
Trophic level transfer efficiency (TLTE) is a measure of the total energy transfer from one trophic level to the next. Due to extensive energy loss as metabolic heat, an average of only 10% of the original energy obtained is passed on to the next level. This pattern of energy loss severely limits the possible number of trophic levels in a food chain.

Ecological Niches

25.9K
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.

Keystone Species01:39

Keystone Species

24.1K
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...

Ecological Disturbance02:26

Ecological Disturbance

20.6K
An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.

Summary

Tree evenness and key species are vital for maintaining boreal-temperate ecotone ecosystem services, not just tree richness. This is crucial for managing these forests under climate change.

Area of Science:

  • Ecology
  • Forest Science
  • Climate Change Biology

Background:

  • Boreal forests are critical for carbon sequestration but are threatened by climate change.
  • Warming temperatures are causing boreal forests to transition into boreal-temperate ecotones, changing their structure and services.
  • The influence of tree diversity and forest structure on multiple ecosystem services in these transitional zones is not well understood.

Purpose of the Study:

  • To investigate how tree richness, evenness, and specific tree species impact multiple ecosystem services in a boreal-temperate ecotone.
  • To understand the relationship between forest structure, tree diversity, and the provision of services like carbon stock, nutrient cycling, and water regulation.

Main Methods:

  • Conducted a field survey across a large boreal-temperate ecotone in eastern Asia.
  • Assessed multiple ecosystem services including carbon stock, nutrient cycling, wood production, decomposition, water regulation, and microbial habitats.
  • Analyzed the effects of tree richness, evenness, and key species on these services.

Main Results:

  • Tree richness declined with increasing latitude, indicating community shifts across the ecotone.
  • Tree evenness and the presence of key species significantly explained variations in ecosystem multiservices.
  • Ecosystem multiservices showed a positive correlation with tree evenness.
  • The impact of tree richness on ecosystem services transitioned from negative to positive as tree evenness increased.

Conclusions:

  • Tree evenness and key species play a more critical role than tree richness alone in supporting multiple ecosystem services in boreal-temperate ecotones.
  • Findings provide essential insights for the effective management of ecosystem services in these vulnerable transitional forests under climate change scenarios.
