Community Ecology Flashcards
number and type of species in a community
community composition
number of different species in an area
richness
number of individuals of a specific species as a percent of total number of individuals present
Abundance (evenness)
spatial patterns in a community
Community structure
number of trophic levels and number of species within them
complexity
production of biomass by photosynthesis
primary productivity
amount of biomass stored after respiration
net primary
recovers quickly from disturbance
resilience
resists changes despite disturbance
stability
shift of community composition/structure over time
Succession
land is bare (i.e., no soil) and colonized by organisms for the first time
Primary
occurs after disturbance, new community develops from old one
secondary
any force that disrupts a community’s composition, structure, function
disturbance
types of disturbances
Small and large scale
Fast and slow
Human and non-human
disturbances are harmful
Organismal view
