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.

Threats to Biodiversity01:50

Threats to Biodiversity

26.5K
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...

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.

What is Conservation Biology?01:57

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.

Ecological Succession02:17

Ecological Succession

21.2K
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...

Habitat Fragmentation02:31

Habitat Fragmentation

20.9K
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.

Area of Science:

  • Ecology
  • Environmental Science
  • Conservation Biology

Background:

  • The planet faces an ecological crisis characterized by depauperated natural systems and declining biodiversity.
  • Environmental tipping points are being approached or crossed, demanding urgent action.
  • Current resources allocated to addressing these challenges are insufficient.

Purpose of the Study:

  • To argue for placing the discipline of ecology on an emergency footing.
  • To address the limitations of current ecological research in the face of global environmental challenges.
  • To explore the potential benefits of a mission-oriented approach in ecology.

Main Methods:

  • This study presents a conceptual argument, synthesizing existing knowledge and perspectives within ecology.
  • It critically evaluates counterarguments against a mission-oriented approach in scientific research.
  • It proposes a shift in research priorities towards addressing pressing environmental issues.

Main Results:

  • Arguments against a mission-oriented ecology are deemed uncompelling.
  • A shift towards mission-relevant research can lead to improved planetary outcomes.
  • Potential benefits exist for researchers, institutions, and funders supporting this transition.

Conclusions:

  • Ecology should adopt an emergency footing to effectively address the current ecological crisis.
  • A mission-oriented approach in ecology, supported by key stakeholders, offers significant advantages.
  • This strategic shift is crucial for achieving better environmental outcomes and advancing ecological science.
