The range map of Geomalacus maculosus shows a 'Lusitanian' distribution. This kind of disjunct distribution of a species, such that it occurs in Iberia and in Ireland, without any intermediate localities, is usually called "Lusitanian" (named after the Roman Province Lusitania, corresponding roughly to modern-day Portugal).
A disjunctive population, in ecology, is a colony of plants, animals, or other organisms whose geographical locus is severed from the continuous range of the bulk of the species distribution. Although a disjunctive population may sometimes occur on an island, [ 1 ] which creates physical separation via water, a large percentage of disjunctive ...
Species distribution models include: presence/absence models, the dispersal/migration models, disturbance models, and abundance models. A prevalent way of creating predicted distribution maps for different species is to reclassify a land cover layer depending on whether or not the species in question would be predicted to habit each cover type.
Antitropical (alternatives include biantitropical or amphitropical) distribution is a type of disjunct distribution where a species or clade exists at comparable latitudes across the equator but not in the tropics. For example, a species may be found north of the Tropic of Cancer and south of the Tropic of Capricorn, but not in between. [1]
Panbiogeography, originally proposed by the French-Italian scholar Léon Croizat (1894–1982) in 1958, [1] [2] is a cartographical approach to biogeography that plots distributions of a particular taxon or group of taxa on maps, and connects the disjunct distribution areas or collection localities together with lines called tracks , regarding vicariance as the primary mechanism for the ...
The conservation status of Brodoa oroarctica warrants particular attention due to its disjunct population pattern and Arctic–alpine habitat requirements. While the species maintains a broad circumpolar distribution in its main Arctic range, its isolated southern populations in eastern North America are of special conservation interest. [4]
The term disjunct can refer to: disjunct (linguistics) disjunct or quincunx in astrology, an aspect made when two planets are 150 degrees, or five signs apart; a disjunct distribution in biology, one in which two closely related taxa are widely separated geographically; disjunct (music), a melodic skip or leap; operand of a logical disjunction
The East Siberian lemming, Eastern Siberian brown lemming, or Ognev's lemming (Lemmus paulus) is a species of lemming endemic to Russia, where it has a disjunct distribution throughout parts of Siberia east of the Verkhoyansk Range.
