Ecological Interactions
From: http://perth.uwlax.edu/faculty/howard/BIO101/Energyflow&communities/sld010.htm

This means that…

No two species can occupy the same ecological niche. or…
Two species cannot coexist unless they are doing things differently because competition will result, and one species will beat out the other.

Consider two species of barnacle, what are the minimum and maximum number of days of submergence within which the species can survive?

From: http://perth.uwlax.edu/faculty/howard/BIO101/Energyflow&communities/sld010.htm

A Niche is defined as, "the limits, for all important environmental features, within which individuals of a species can survive, grow and reproduce.”
From: http://perth.uwlax.edu/faculty/howard/BIO101/Energyflow&communities/sld013.htm

Mutualism =

Commensalism =

Parasitism =

species 1 species 2

Connell's conclusions
What is the difference between resource partitioning or character displacement?
Not to be confused with predation
Connell Found the that...
or attempts to avoid predation
Some species are ecosystem engineers
What can we learn from ants?
Practice Question: Why do moderate levels of disturbance result in an increase in community diversity?
A) Habitats are opened up for less competitive species.
B) Competitively dominant species infrequently exclude less competitive species after a moderate disturbance.
C) The environmental conditions become optimal.
D) The resulting uniform habitat supports stability, which in turn supports diversity.

and disturbance
