ecology 1 Flashcards
study on relationships between a organism’s and its envirobent
ecology
“oikos”
family
scientific method
- make observations.
- generate questions
3.generate hypothesis
4 design an experiment

living organisms fundamental unit of populations and communities
individuals
group of individuals of a species
populations
an assemblages of species populations occurring together in space and time
communities
a collection of two related components (biotic & abiotic) that function as a unit
ecosystem
2 basic interacting components of an ecosystem
living/biotic and physical/abiotic
set of phenomena that can be explained only by looking at a particular hierarchical level
emergent properties
basic unit of ecology
individual
study of how behavior of individuals affect their ability to survive and reproduce
behavioral ecology
study of how physical factors affect the survival and reproduction of individual organisms
physiological ecology (autecology)
study of environment influence on the evolution of organism
evolution ecology
study of how groups of individuals grow and reproduce
population ecology
study of how populations from different species interact to mutually affect each populations growth and survival .
community ecology
study of the whole living system with focus on the flow of energy and biomass in large scale living systems
ecosystem ecology
study of spacial patterns and underlying mechanisms
landscape ecology
uses GIS and the goal is to predict the responses of apparent organisms to changes in landscape to ultimately facilitate ecosystem management
landscape ecology
German zoologist , who originally coined the term ecology in 1866
Ernst
Haeckel
an area of land (or water) composed of a patchwork of communities and ecosystems.
landscape
The broad-scale regions
dominated by similar types of ecosystems, such as tropical rain
forests, grasslands, and deserts, are referred to as
biomes
highest level of organization of ecological systems—the thin layer surrounding the Earth that supports all of life. I
biosphere
are abstract, simplified representations of real systems.
Models
may be mathematical, like computer simulations, or they may be verbally descriptive, like Darwin’s theory of evolution by natural selection
models
typically reserved for
circumstances in which the hypothesis has at least some limited
support through observations and experimental results.
models
near surface temperatures warmer than they
would be without this blanket of gases. This is known as the
“greenhouse effect,”
One moves northward toward the pole, diverted
to the right by the Coriolis effect to become the
prevailing westerlies
the other current moves southward toward the equator. Also deflected to the right, this southward flowing stream becomes the strong, reliable winds that were called
trade winds
