Chapter 54: Community Ecology I Flashcards
1
Q
Community
A
Group of species living close enough to interact with each toher
2
Q
Physical boundaries of a community are defined…?
A
- By the ecologist to match their research questions
3
Q
Community ecology (def.)
A
Study of how interactions between species affect structure and organization of communities
4
Q
Interspecific interactions
A
Interactions between individuals of different species
5
Q
Competition
A
- / -
- Individuals of different species that compete for a resource that limits their growth or survival
- Resource must be in short supply
6
Q
Predation
A
- / -
- One species kills and eat s the other species
- Most species are adapted for capturing prey
7
Q
Mutualism
A
- / +
- Both species benefit
8
Q
Commensalism
A
- / 0
9
Q
Infraspecific interactions
A
- Interactions between a species
10
Q
Community ecologists focus on what sort of interactions?
A
- Focus on interspecific interactions
11
Q
Competitive exclusion principle
A
- Two species competing for the same limiting resources cannot coexist in the same place
- In constant conditions, superior competitor will out-compete the inferior competitor
12
Q
Niche
A
- Biotic and abiotic factors a species uses (plus ecological role)
13
Q
Niche partitioning
A
- Niches located in different areas
- Ex: Plant root systems
14
Q
Fundamental niche
A
- Niche that species could POTENTIALLY occupy
15
Q
Realized niche
A
- Niche that species actually occupies
