4), and classification as allopatric
This indicates deep divergence among the 3 major parasite subpopulations that infect humans, 2 of which are sympatric and predominantly associated with different reservoir hosts (long-tailed and pig-tailed macaques in Malaysian Borneo), and 1 of which is allopatric
in a different geographic region (peninsular Malaysia).
norstogii complex probably emerged from an allopatric
speciation process resulting from recent and ongoing divergence processes due to drift stemming from founder effects, resulting in alleles from the original populations becoming fixed in most of the surviving populations.
A symptomatic feature of chromosome variation in mole rats and, particularly, in Nannospalax species, is the occurrence of populations, possessing a specific karyotype and distributed in a parapatric or allopatric
According to the distribution records and the Identification, the two species are not strictly allopatric
Cytogenetic comparison between two allopatric
populations of Astyanax altiparanae Garutti et Britski, 2000 (Teleostei, Characidae), with emphasis on the localization of 18S and 5S rDNA.
Because the allopatric
technique is simpler, requires less data, and has been used in past studies, we employed it to make more direct comparisons to regional studies.
Attraction of the southern pine beetle, Dendroctonus frontalis, to pheromone components of the western pine beetle, Dendroctonus brevicomis (Coleoptera: Curculionidae: Scolytinae), in an allopatric
Detailed local data sets are beneficial for comparisons to allopatric
populations of the same species (and closely related species) inhabiting similar and different environments.
To illustrate one of the typical divergent processes, we will mention the case of the allopatric
origin of some Polypodium L.
The intricacies of the Gould-Eldredge interaction, their efforts to address their critics, and the relationship of their proposals concerning speciation models and in particular concerning Ernst Mayr's allopatric
speciation model are thoroughly and fairly explicated.
Anecdotal evidence suggests that El Nino Southern Oscillation (ENSO) plays significant roles in range expansions and contractions of both species (Kerstitch and Bertsch 2007), which otherwise have allopatric
ranges, with the boundary at Punta Eugenia and Isla Cedros, Mexico (Angulo Campillo 2003, 2005).
Each crater lake can be seen as a "natural experiment" of sympatric and allopatric
albopictus has been investigated (5-6), it is still difficult foreseeing the spatial mosaic of sympatric or allopatric
scenarios in habitats of Ae.
In sea urchins, the sperm binding protein bindin is under positive selection in a number of species (Metz and Palumbi, 1996; Palumbi and Lessios, 2005; Lessios, 2007), although the rate of evolution appears to be faster between sympatric species than between allopatric
species (Metz et al.
