Why do communities and ecosystems change
by basis of interactions among populations and disruptions to enviroments
How is the structure of a community measured and described
in terms of species composition and species diversity
What is the Simpson’s Diversity Index
What determines how populations access energy and matter within a community
interactions
What are the characterizations of relationship interactions
positive and negative
What are examples of positive and negative characterized interactions
predator/prey interactions
trophic cascades
niche partitoring
What can drive population dynamics
competition
predation
symbiosis
What are the types and results of symbiosis
parasitism- positive/negative
commensalism- postive/neutral
mutualism- positive/positive
What does cooperation or coordination between organisms, populations, and species result in
enhanced movement of matter and energy
What communities are less resilient to changes within the environment
communities with low component parts and little diversity
What can influence the organization of the ecosystem
diversity of species
What is important about keystone species
regardless of abundance, they hold up ecosystems, removal almost always results in ecosystem collapse
