Ecological Niches

26.6K
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.

Ecological Disturbance02:26

Ecological Disturbance

21.1K
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.

What is Conservation Biology?

24.3K
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.

Ecological Succession02:17

Ecological Succession

21.5K
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...

Multi-species Conserved Sequences

4.8K
Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale  studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved...

Keystone Species01:39

Keystone Species

24.8K
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...

Area of Science:

  • Conservation Biology
  • Ecology
  • Ecosystem Management

Background:

  • Effective conservation requires species to maintain ecological roles, not just survival.
  • Current management and policy often overlook species' functional importance in ecosystems.
  • Population Viability Analysis (PVA) is a common tool, but it doesn't fully capture ecological function.

Purpose of the Study:

  • To present a novel framework for quantifying ecological function.
  • To integrate ecological function into conservation planning alongside population viability.
  • To address the gap in managing for species' roles in ecosystem maintenance.

Main Methods:

  • Introduce Ecological Function Analysis (EFA) as a complementary approach to PVA.
  • Focus EFA on preventing secondary extinctions and preserving ecosystem structure and processes.
  • Utilize various modeling approaches within the EFA framework.

Main Results:

  • EFA provides a quantifiable method to assess and manage ecological function.
  • The framework allows for the integration of functional considerations into conservation strategies.
  • EFA identifies key species or functions crucial for ecosystem health, even with weak interactions.

Conclusions:

  • Ecological Function Analysis (EFA) enhances conservation by focusing on species' ecosystem roles.
  • EFA is a realistic approach, requiring analysis of relatively few species or functions.
  • Integrating EFA into planning can improve ecosystem resilience and prevent cascading extinctions.
