Disease ecology. Disease ecology is a sub-discipline of ecology concerned with the mechanisms, patterns, and effects of host-pathogen interactions, particularly those of infectious diseases. [1] For example, it examines how parasites spread through and influence wildlife populations and communities.
Infectious disease. Waterborne diseases are conditions (meaning adverse effects on human health, such as death, disability, illness or disorders) [1] : 47 caused by pathogenic micro-organisms that are transmitted by water. These diseases can be spread while bathing, washing, drinking water, or by eating food exposed to contaminated water. [2]
Ecosystem health. Ecosystem health is a metaphor used to describe the condition of an ecosystem. [1] [2] Ecosystem condition can vary as a result of fire, flooding, drought, extinctions, invasive species, climate change, mining, fishing, farming or logging, chemical spills, and a host of other reasons. There is no universally accepted benchmark ...
Crises caused by abiotic factors. Climate change is starting to have major impacts on ecosystems. With global temperature rising, there is a decrease in snow-fall, and sea levels are rising. Ecosystems will change or evolve to cope with the increase in temperature. Consequently, many species are being driven out of their habitats.
Tropical disease. Tropical diseases are diseases that are prevalent in or unique to tropical and subtropical regions. [1] The diseases are less prevalent in temperate climates, due in part to the occurrence of a cold season, which controls the insect population by forcing hibernation. However, many were present in northern Europe and northern ...
Natural reservoir. In infectious disease ecology and epidemiology, a natural reservoir, also known as a disease reservoir or a reservoir of infection, is the population of organisms or the specific environment in which an infectious pathogen naturally lives and reproduces, or upon which the pathogen primarily depends for its survival.
An organism that feeds primarily or exclusively on bacteria. A branch of ecology which studies the ecological and evolutionary basis of animal behavior, mainly at the level of individual animals. The ratio between regional and local species diversity, or the difference in diversity between different habitats.
Health ecology (also known as eco-health) is an emerging field that studies the impact of ecosystems on human health. It examines alterations in the biological, physical, social, and economic environments to understand how these changes affect mental and physical human health. Health ecology focuses on a transdisciplinary approach to ...
