phylogenetic species concept
Give this one a try later!
smallest monophyletic group on phylogenetic tree
allopatric speciation
Give this one a try later!
The formation of new species in populations that are geographically
isolated from one another.
short term consequence
,Give this one a try later!
competitive exclusion-where organisms shift their niche in presence of the
stronger competitor
adaptive radiation
Give this one a try later!
divergence of many new species from a single ancestral species, usually by
a rapid process often tied to the colonization of new empty niches
logistic growth model
Give this one a try later!
S shaped curve, early growth may be exponential but slows
down due to population approaching carrying capacity (K)
ancestral character (trait)
Give this one a try later!
a character that existed in an ancestor
, density independent
Give this one a try later!
not impacted by how many individuals/areas, BUT are impacted by abiotic
factors (climate) (frost, fire, flooding, storm damage) (not influenced by
changes in population density)
ecosystem ecology
Give this one a try later!
cycling of energy and matter
