Term
|
Definition
| arrangement of diversity into natural classification |
|
|
Term
|
Definition
| applies to distinct population segment of species which interbreeds when mature |
|
|
Term
| morphological (linnaeus) concept |
|
Definition
| smallest group of individuals distinct and distinguishable from all others; can misclassify based on differences that can be maintained w/in an interbreeding group; depends solely on observable morphological differences |
|
|
Term
|
Definition
| population or group of populations that share common evolutionary fate and historical tendencies based on lineage; recognizes more than just genetic and morphological differences; difficult to determine "evolutionary fate"; how much diversity allowed w/in a common evolutionary fate? |
|
|
Term
| Biological (mayr) concept |
|
Definition
| group of populations of individuals similar in form and function and reproductively isolated from other pops;includes genetic info; ignores hybridization; dependent on geographic isolation to achieve species status |
|
|
Term
|
Definition
| how pops become distinct species? for each pop to become diff evolutionary lineages process whereby gene flow is reduced sufficiently b/w sister pops: allopatric and non-allopatric |
|
|
Term
|
Definition
| with geographic isolation; vicariant, founder, reinforcement |
|
|
Term
|
Definition
| large pops geographically isolated(little inbreeding) |
|
|
Term
|
Definition
| small pop becomes geographically isolated and reproductively isolated via inbreeding, selection, drift |
|
|
Term
|
Definition
| early isolation followed by sympatry(living together), but selection against hybrids |
|
|
Term
|
Definition
| without geographic isolation; sympatric and parapatric |
|
|
Term
|
Definition
| sister species evolve w/in dispersal range of eachother, but adapt to diff habitats: habitat-dependent assortative mating |
|
|
Term
| parapatric non-allopatric |
|
Definition
| sister species evolve in segregated habitats across narrow contact zone, little mixing in spite of proximity |
|
|
Term
|
Definition
| genus always noun, species usually adjective(binomial)epithet; species name can be given to more than one; each new species reported in journal, must have specimens available for study |
|
|
Term
|
Definition
| holotype, paratype, lectotype, neotype, paralectotype, syntype, topotype |
|
|
Term
|
Definition
| single specimen as name-bearing type of species when established, single specimen on which taxon based when no type specified |
|
|
Term
|
Definition
| each specimen of type series other than holotype |
|
|
Term
|
Definition
| syntype designated as single name-bearing type speciment subsequent to establishment of nomial species or subspecies |
|
|
Term
|
Definition
| single specimen designated as name-bearing type of nominal species or subspecies for which no holotype, lectotype, syntypes, or prior neotype exists |
|
|
Term
|
Definition
| each specimen of former syntype series remaning after designation of lectotype |
|
|
Term
|
Definition
| each specimen of type series from which neither holotype nor lectotype has been designated |
|
|
Term
|
Definition
| term for specimen originating from type locality of species or subspecies to which it belongs, whether or not specimen is part of type series |
