Chapter 1: What is Ecology
- Overview of ecology
- The study of relationships between organisms and the environment
- Natural history: background of organisms such as how long they live,
reproductive habits, and nutritional requirements
- Biotic and Abiotic: the biotic influences the abiotic and the abiotic drives the biotic
- Biotic ⇄ Abiotic
- Lab to field: can lab results be extended to the field
- Physiological to global scale: individuals - populations - communities -
ecosystems - landscape
- Individuals
- Physiological and behavioural ecologists; understand morphology
- Rely on evolutionary theory and organismal biology such as
adaptations and behaviour
- Population
- A group of individuals
- Population and conservation biologists
- Link between individuals and populations
- Factors influencing population structure and dynamics
- Distribution and abundance
- Population growth and regulation
- Conservation
- Community
- Community ecologists
- Individuals interact with others from a number of different species
- Interactions: predation, parasitism, mutualism, and competition
- Evolutionary effects of the interactions and effects of the
interactions on properties of communities
- Ecosystem
- Ecosystem ecologists
- Include biological, chemical, and physical processes and
interactions
- Within one location
- Landscape
- Landscape ecologists
- Identify and study isolated communities and ecosystems
- All communities are “open” systems - things can move within, in,
and out
- Region
- (eco)Regional ecology
- Landscapes are not isolated
- Parts of regions subject to large-scale and long term regional
processes
- Biosphere

Document Summary
The study of relationships between organisms and the environment. Natural history: background of organisms such as how long they live, reproductive habits, and nutritional requirements. Biotic and abiotic: the biotic influences the abiotic and the abiotic drives the biotic. Lab to field: can lab results be extended to the field. Physiological to global scale: individuals - populations - communities - ecosystems - landscape. Rely on evolutionary theory and organismal biology such as adaptations and behaviour. Evolutionary effects of the interactions and effects of the. Individuals interact with others from a number of different species. Interactions: predation, parasitism, mutualism, and competition interactions on properties of communities. Include biological, chemical, and physical processes and interactions. All communities are open systems - things can move within, in, Identify and study isolated communities and ecosystems and out. Parts of regions subject to large-scale and long term regional processes. Regions not isolated either; processes and patterns subject to macroecology.
