Ecological Succession02:17

Ecological Succession

21.1K
Ecological succession is influenced by the processes of facilitation, inhibition, and toleration. Facilitation occurs when early successional species create more favorable ecological conditions for subsequent species, such as enhanced nutrient, water, or light availability. In contrast, inhibition happens when early successional species create unfavorable ecological conditions for potential successive species, such as limiting resource availability. In some cases, later successional species...

What is Biodiversity?01:19

What is Biodiversity?

32.2K
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.

Ecological Disturbance02:26

Ecological Disturbance

20.5K
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.

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.

Threats to Biodiversity01:50

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...

Biodiversity and Human Values

16.3K
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.

Area of Science:

  • Ecology
  • Environmental Science
  • Conservation Biology

Background:

  • Existing research on biodiversity-ecosystem functioning (BEF) primarily focuses on small spatial scales.
  • The influence of spatial and temporal scales on BEF relationships is not fully understood.

Purpose of the Study:

  • To review current theory on the scale dependence of BEF relationships.
  • To identify key expectations for how BEF relationships change across spatial and temporal scales.
  • To propose future research directions for integrating metaecosystem and metacommunity ecology.

Main Methods:

  • Theoretical review of existing literature on biodiversity and ecosystem functioning.
  • Identification of six key expectations for scale dependence in BEF relationships.
  • Discussion of potential methods for testing these theories, including remote sensing and networked experiments.

Main Results:

  • BEF relationships exhibit scale dependence, with nonlinear changes in slope and stability related to spatial scale and extent.
  • Coexistence, temporal autocorrelation, metacommunity connectivity, and food web structure all influence BEF relationships across scales.
  • Anthropogenic land cover change can alter the scaling of BEF relationships.

Conclusions:

  • Scale is a critical factor influencing biodiversity and ecosystem functioning.
  • Future research should integrate metaecosystem and metacommunity approaches to understand cross-scale feedbacks.
  • Understanding scale-dependent BEF dynamics is essential for effective biodiversity and ecosystem management policies.
