Cascade effect (ecology), the Glossary

An ecological cascade effect is a series of secondary extinctions that are triggered by the primary extinction of a key species in an ecosystem.^[1]

Doomsday scenarios

Algae

Algae (alga) are any of a large and diverse group of photosynthetic, eukaryotic organisms.

See Cascade effect (ecology) and Algae

Amphibian

Amphibians are ectothermic, anamniotic, four-limbed vertebrate animals that constitute the class Amphibia.

See Cascade effect (ecology) and Amphibian

Biodiversity

Biodiversity (or biological diversity) is the variety and variability of life on Earth. Cascade effect (ecology) and Biodiversity are conservation biology.

See Cascade effect (ecology) and Biodiversity

Competition (biology)

Competition is an interaction between organisms or species in which both require a resource that is in limited supply (such as food, water, or territory).

See Cascade effect (ecology) and Competition (biology)

Crayfish

Crayfish are freshwater crustaceans belonging to the infraorder Astacidea, which also contains lobsters.

See Cascade effect (ecology) and Crayfish

Critical transitions are abrupt shifts in the state of ecosystems, the climate, financial systems or other complex dynamical systems that may occur when changing conditions pass a critical or bifurcation point.

See Cascade effect (ecology) and Critical transition

Defaunation

Defaunation is the global, local, or functional extinction of animal populations or species from ecological communities.

See Cascade effect (ecology) and Defaunation

Ecological release

Ecological release refers to a population increase or population explosion that occurs when a species is freed from limiting factors in its environment. Cascade effect (ecology) and Ecological release are conservation biology.

See Cascade effect (ecology) and Ecological release

Ecosystem

An ecosystem (or ecological system) is a system that environments and their organisms form through their interaction.

See Cascade effect (ecology) and Ecosystem

Estuary

An estuary is a partially enclosed coastal body of brackish water with one or more rivers or streams flowing into it, and with a free connection to the open sea.

See Cascade effect (ecology) and Estuary

Extinction

Extinction is the termination of a taxon by the death of its last member.

See Cascade effect (ecology) and Extinction

Generalist and specialist species

A generalist species is able to thrive in a wide variety of environmental conditions and can make use of a variety of different resources (for example, a heterotroph with a varied diet).

See Cascade effect (ecology) and Generalist and specialist species

Greenpeace

Greenpeace is an independent global campaigning network, founded in Canada in 1971 by a group of environmental activists.

See Cascade effect (ecology) and Greenpeace

Herbivore

A herbivore is an animal anatomically and physiologically adapted to eating plant material, for example foliage or marine algae, for the main component of its diet. Cascade effect (ecology) and herbivore are ecology terminology.

See Cascade effect (ecology) and Herbivore

International Union for Conservation of Nature

The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources.

See Cascade effect (ecology) and International Union for Conservation of Nature

Invasive species

An invasive species is an introduced species that harms its new environment.

See Cascade effect (ecology) and Invasive species

Kelp

Kelps are large brown algae or seaweeds that make up the order Laminariales.

See Cascade effect (ecology) and Kelp

Kelp forest

Kelp forests are underwater areas with a high density of kelp, which covers a large part of the world's coastlines.

See Cascade effect (ecology) and Kelp forest

Mollusca

Mollusca is the second-largest phylum of invertebrate animals, after Arthropoda; members are known as molluscs or mollusks.

See Cascade effect (ecology) and Mollusca

Mutualism (biology)

Mutualism describes the ecological interaction between two or more species where each species has a net benefit.

See Cascade effect (ecology) and Mutualism (biology)

Organism

An organism is defined in a medical dictionary as any living thing that functions as an individual.

See Cascade effect (ecology) and Organism

Overexploitation

Overexploitation, also called overharvesting, refers to harvesting a renewable resource to the point of diminishing returns.

See Cascade effect (ecology) and Overexploitation

Predation

Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey.

See Cascade effect (ecology) and Predation

Sea otter

The sea otter (Enhydra lutris) is a marine mammal native to the coasts of the northern and eastern North Pacific Ocean.

See Cascade effect (ecology) and Sea otter

Sea urchin

Sea urchins or urchins, alternatively known as sea hedgehogs, are typically spiny, globular animals, echinoderms in the class Echinoidea.

See Cascade effect (ecology) and Sea urchin

Species

A species (species) is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction.

See Cascade effect (ecology) and Species

Trophic cascade

Trophic cascades are powerful indirect interactions that can control entire ecosystems, occurring when a trophic level in a food web is suppressed.

See Cascade effect (ecology) and Trophic cascade

Tropical forest

Tropical forests are forested ecoregions with tropical climates – that is, land areas approximately bounded by the tropics of Cancer and Capricorn, but possibly affected by other factors such as prevailing winds.

See Cascade effect (ecology) and Tropical forest

World Wide Fund for Nature

The World Wide Fund for Nature (WWF) is a Swiss-based international non-governmental organization founded in 1961 that works in the field of wilderness preservation and the reduction of human impact on the environment.
