Contrasting patterns of gene flow between sister plant species in the understory of African moist forests-The case of sympatric and parapatric
labiosus have their ranges virtually parapatric
The situation could be more complicated if formerly allo- or parapatric
species start to occupy the same area due to expansion or range shift (Swihart et al.
Some of these Jivarus species occur sympatrically, but most have small ranges and many seem to be parapatric
or form populations that are isolated from one another.
Hemiptera: Reduviidae: Triatominae) in Chile and its parapatric
model of speciation.
Based on the hypothesis of parapatric
speciation between Panopea generosa and Panopea globosa, nuclear genes were used to provide molecular evidence of ancient phylogeny between them, and included other species of the genus for a broader comparison.
Habitat use by parapatric
rabbits in a Mexican high-altitude grassland system.
Firsthand experience with and knowledge of the seasonal male advertisement call characteristics is also important so it can be distinguished with certainty from the other natural "trilling" sounds produced by sympatric or parapatric
species (red-spotted toad, Anaxyrus punctatus; Lesser Nighthawk, Chordeiles acutipennis; and possibly insects).
Hybridization between chromosome races of the Sceloporus grammicus complex (Phrynosomatidae): structure of the Ajusco Transect.
The ranges of these 2 species within the Pacific Northwest are considered parapatric
, in concordance with division across the Cascades (Fig.
in the upper and lower Amazon, such findings may provide interesting examples of parapatric
speciation due to reduced gene flow over enormous distances (Ritchie 2001).
The vertical distribution of pronophiline butterflies (Nymphalidae, Satyrinae) along an elevational transect in Monte Zerpa (Cordillera de Merida, Venezuela) with remarks on their diversity and parapatric
