Key Concepts

Pollution

Pollution involves the introduction of contaminants into natural environments, which can disrupt ecosystems and harm wildlife. In the context of species conservation, pollution can lead to toxic exposures, affect reproductive health, and modify habitat conditions, making it a significant factor contributing to population declines and extinctions.

Infectious Diseases

Infectious diseases, particularly emerging pathogens, are a major threat in wildlife conservation. Diseases can decimate populations by causing high mortality rates and may spread quickly among individuals, especially in species with low immunity. In amphibians, for instance, fungal infections have repeatedly been linked to dramatic population declines.

Climate Change

Climate change refers to the long-term alteration of temperature and typical weather patterns in a region, largely driven by human-induced factors. It plays a critical role in conservation biology by influencing species distributions, altering breeding seasons, and affecting the availability of food and water, thereby increasing the risk of extinction for sensitive species.

Habitat Loss and Fragmentation

Habitat loss and fragmentation occur when natural environments are altered or reduced in size due to human activity or natural processes. In broader conservation biology, this concept explains how the reduction of living space and the breaking up of continuous habitats can isolate populations, reduce genetic diversity, and make species more vulnerable to extinction.
