Unit 5- Population Dynamics Flashcards
Niche
The role or function of an organism or species in an ecosystem
Interspecies competition
Competition between species
Resource partitioning
One way in which species occupying a similar ecological niche can reduce competition is through resource partitioning
Biodiversity
The variety of life in the world or in a particular habitat or ecosystem
Indigenous species
A species is defines as native to a given region or ecosystem if its presence in that region is the result of only natural processes, with no human intervention
Natality
The birth rate in a population
Biotic potential
Highest possible per capita growth rate
Mutualism
An interaction in which both partners benefit
Parasitism
An interaction in which one species benefits and the other is harmed
Commensalism
An interaction in which one species benefits and the other is unaffected
Carrying capacity
The number of individuals in a population that the environmental resources can support
Non-native species
A species of animal or plant that was brought to one place from another country or continent, usually by humans
Density-dependent factors
Intraspecific competition Interspecific competition Predation Disease Allee effect Minimum viable population size
Density-Independent factors
