TERMINOLOGIES USED IN ECOHEALTH
Ecosystem Health
•
Eco health recognizes the inherent interdependence of the health of
humans, animals and ecosystems and explores the perspectives
,theories, methodologies emerging at the interface between ecological
and health sciences. (Wilcox 2004
•
Ecosystems are dynamic and subject to both natural and human
perturbations such as fire, flooding, drought, extinctions, invasive
species, climate change, mining, fishing, farming, logging, and oil spills.
While there is no universally accepted benchmark for a healthy
ecosystem, there are common signs indicative of the degradation of
ecosystems.
•
One Health;
is the collaborative effort of multiple health
science professions together with their related disciplines
and institutions- working locally ,nationally, and globally- to
attain optimal health of people, domestic animals, wildlife,
plants and our environment.(One Health commission
definition)
•
Ecosystem
; an
ecosystem
is a
community
of living
organisms in conjunction with the
non-living
components
of their environment (things like air, water and
mineral soil), interacting as a system to generate energy.
Prepared By Associate Professor Lawrence Mugisha, 2016
•
Abiotic
: Physical, or nonliving, factors that shape an
ecosystem. Examples include rocks, climate, pressure, soils,
precipitation, sunlight, winds and humidity. These abiotic
have a direct influence on living things.
•
Biotic:
Living factors such as plants, animals, fungi, protist
and bacteria are all biotic or living factors. Biotic factors
depend on abiotic factors to survive. The kind of biotic
factors (living organisms) in a given area is often as a result
of abiotic conditions of that area.

•
Habitat
: the area where an organism lives, including the biotic and abiotic
factors that affect it.
•
Bio diversity
; this includes the variety of all life on earth and the natural
patterns it forms. Biodiversity has got 3 key elements. these include;
•
Ecological diversity
; (biomes, provinces, ecoregions, ecosystem,
habitat)
•
Genetic diversity;
(populations, individuals, chromosomes, genes,
nucleotides)
•
Organismal diversity;
phyla, families, genera, species, subspecies,
population, individuals
Prepared By Associate Professor Lawrence Mugisha, 2016
•
Symbiosis
: Relationship in which two species live closely together,
usually benefiting from each other. There are three types of this
relationship:
a. Parasitism: parasite benefits, host is hurt.
b.
Commensalism: one species benefits, the other is neither hurt nor
helped.
c.
Mutualism: both species benefit.
•
Adaptation:
This is the ability of an organism to use suitable measures
and mechanisms to survive in its environment. A good example is the
polar bear. It helps it to camouflage, so its prey cannot see it. Its thick
fur also provides the warmth to help it survive in its frozen
environment.
Ecosystem health and EcoHealth explore the interconnectedness of humans, animals, and ecosystems. Concepts like One Health emphasize collaboration for optimal health across species. Terms like abiotic, biotic, habitat, and biodiversity are key in understanding ecosystems and their health. Symbiosis illustrates how species can interact, benefiting or harming each other. These terms provide a foundation for studying the dynamic relationships within ecosystems and promoting environmental well-being.
