Diversity Flashcards
community
Associatation of interacting species inhabiting a difined area
guild
Group of organisms that eats similar type of pray/food eg. seed eaters, fruit eaters, filter feeders
life forms/ functional groups
Combination of structures and grwoth dynamics that characterize plants into groups eg. trees, vines, grasses
Log-normal distriution
Most species are moderatyl abundant, few are abundant or rare
species diversity
Includes richness and eveness
species richness
The number of species
species eveness
The relative abundance
rank abundance curves
Plot with relatives abundace of speceis against their rank in abundace
Things that affect species diverstiy
1- enviromental complexity
2-nutrient availability
3- disturbance
What is disturbance
A discrete event that disrupts ecosystems, community or population strcutre and changes resources, substratre availability or physical envieormnt
Disrupture from avarage conditions
