Ecosystems & Ecophysiology course deals with the interactions between organisms and the physical environment. Two halves, ecology and physiology. Ecology – The study of biophysical, biochemical, and physiological processes used by animals to cope with factors of their physical environment, or employed during ecological interactions with other organisms (animal).
The ecosystem is all living communities (biotic) and their associated non-living (a biotic) environmental components in a defined area. Individuals of the same species = POPULATION, POPULATION + Populations of other species = COMMUNITY, COMMUNITY + non-living part of the environment = ECOSYSTEM Physiology – study of the functioning of organisms – how they work. Ecophysiology– function in relation to particular environments or niches Or Examines how the physiological functions of organisms influence the way they interact with the environment, both biotic and a biotic. The natural environment in which organisms live has two components:
1. A biotic – characterized by physical and chemical factors – i.e. temperature, rainfall, pressure, Ph, water, light &wind, Climate.
2. Biotic – all living organisms, which interact with each other– i.e. Competition
Niche- the range of environmental factors over which an individual can have positive fitness" (for an organism/species). Describes the environmental factors to which an organism has adapted. Niches have two components:The ABIOTIC component& The BIOTIC component. Focus on aquatic ecosystems, both marine (sw) & freshwater (fw). These combine a high level of diversity but with common features based on the physical properties of water. Aquatic Animal Ecophysiology The relationships between important environmental parameters and the physiology of aquatic animals.
