Keystone Species

Keystone Species

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...

Threats to Biodiversity

Threats to Biodiversity

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...

Bioremediation

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Ecological Succession

Ecological Succession

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...

The Soil Ecosystem

The Soil Ecosystem

Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:

Area of Science:

Ecology
Environmental Science
Freshwater Biology

Background:

Beavers are keystone species known as ecosystem engineers.
Their activities profoundly impact hydrological, geomorphological, and ecological processes.
Recent reintroductions and natural expansion have increased beaver populations in Europe.

Purpose of the Study:

To review the current scientific understanding of beaver impacts on ecosystems.
To synthesize knowledge on beavers as ecosystem engineers with a European focus, including North American counterparts.
To inform management strategies for increasing beaver populations in managed landscapes.

Main Methods:

Literature review of scientific research on beaver impacts.
Synthesis of studies on both *Castor fiber* (Eurasian beaver) and *Castor canadensis* (North American beaver).
Analysis of beaver effects on ecosystem structure, geomorphology, hydrology, water quality, freshwater ecology, and human society.

Main Results:

Beavers significantly alter ecosystem structure and geomorphology through dam construction.
Beaver activity influences hydrology, water resources, and water quality.
Beavers impact freshwater ecology and have considerable societal implications.

Conclusions:

Beaver populations are expanding in Europe, necessitating an understanding of their impacts in managed landscapes.
Beavers provide valuable ecosystem services that can aid in water resource management.
Effective management strategies are required to maximize beaver benefits and minimize human-wildlife conflicts.
