Quick Reference

Carrying Capacity

The maximum number of individuals of a species that a given habitat can sustainably support over time, determined by available food, water, shelter, and space. When populations exceed carrying capacity, resources become depleted, leading to population decline.

Habitat Fragmentation

The process by which large, continuous areas of habitat are broken into smaller, isolated patches by human development, roads, agriculture, or other land-use changes. Fragmentation reduces habitat quality, limits animal movement, and decreases genetic diversity.

Population Dynamics

The study of how and why wildlife populations change in size and composition over time. Key factors include birth rates, death rates, immigration, emigration, disease, predation, and density-dependent and density-independent factors.

Mark-Recapture Method

A field technique used to estimate population size by capturing, marking, releasing, and later recapturing a sample of animals. The ratio of marked to unmarked individuals in the recapture sample allows calculation of the total population estimate.

Biodiversity

The variety of life at all levels of biological organization, including genetic diversity within species, species diversity within ecosystems, and ecosystem diversity across landscapes. Biodiversity is essential for ecosystem resilience and function.

Invasive Species Management

Strategies to prevent, control, or eradicate non-native species that threaten native wildlife, habitat integrity, and ecosystem function. Invasive species often lack natural predators and outcompete native organisms for resources.

Wildlife Corridor

A strip of habitat connecting two or more larger habitat areas that allows animals to move safely between them. Corridors maintain genetic diversity, enable seasonal migration, and reduce the negative effects of habitat fragmentation.

Adaptive Management

A structured, iterative decision-making process that treats management actions as experiments, monitors outcomes, and adjusts strategies based on what is learned. This approach allows wildlife managers to improve practices over time despite uncertainty.

Endangered Species Recovery

Coordinated conservation efforts aimed at increasing the population of a species that has declined to critically low levels. Recovery plans may include captive breeding, habitat restoration, legal protection, reintroduction programs, and threat mitigation.

Human-Wildlife Conflict

Situations where the needs and behaviors of wildlife and humans overlap and come into conflict, resulting in negative consequences for one or both parties. Management strategies aim to reduce conflict through deterrents, barriers, compensation, and education.

Key Terms at a Glance

Adaptive Management:An iterative management approach that monitors outcomes and adjusts strategies based on what is learned.

Biodiversity:The variety and variability of life at genetic, species, and ecosystem levels.

Captive Breeding:Breeding wildlife in controlled environments to increase population numbers for conservation or reintroduction.

Carrying Capacity:The maximum population size a habitat can sustainably support given available resources.

CITES:Convention on International Trade in Endangered Species, regulating cross-border wildlife trade.

Conservation Biology:The scientific study of the protection and management of biodiversity to prevent species extinction and habitat loss.

Density-Dependent Factor:A population regulation factor whose influence increases as population density rises.

Density-Independent Factor:A factor affecting population size regardless of density, such as natural disasters or extreme weather.

Ecosystem:A community of living organisms interacting with their physical environment as a functional unit.

Edge Effect:Ecological changes at the boundary between two habitats that can alter species composition and abundance.

Endangered Species Act:A 1973 U.S. law providing protection for species at risk of extinction and their critical habitats.

GIS:Geographic Information Systems used for spatial analysis of habitats, land use, and wildlife distribution.

Habitat Fragmentation:The process of breaking continuous habitat into smaller, isolated patches through human activity.

Home Range:The area in which an individual animal normally lives, feeds, mates, and raises offspring.

Human-Wildlife Conflict:Negative interactions between wildlife and humans, such as crop damage, livestock depredation, or property destruction.
