Thus, allopatric or peripatric distributions of populations or species are inconsistent with parapatric, peripatric, or sympatric divergence without major changes in distribution of one or both daughter lineages; parapatric distributions are inconsistent with sympatric divergence, but may result from peripatric or allopatric divergence with minor changes in breeding distributions; and sympatric distributions are most consistent with sympatric divergence, but may result if allopatric, parapatric, or peripatric divergence are followed by changes in breeding distributions.
Over the last six decades, the debate on the role of ecological interactions and mechanisms depicting the coexistence of sympatric carnivore species (large felids and canids) continues.
The reason for the low prevalence of WNV in these California owls despite a high prevalence in sympatric avian species in the same region is unknown and should be a topic for further research.
To the Editor: The timely study on the relative risk for ehrlichiosis and Lyme disease in which the tick vectors, Amblyomma americanum and Ixodes scapularis, are sympatric notes that knowledge of tickborne diseases is "startlingly low" (1).
heterophylla is the only representative of the genus in the studied site, thus selfing is not likely a mechanism to reduce interspecific pollen flow among sympatric species as proposed by Matallana et al.
Differences in the body sizes of sympatric herbivores may mean they prefer forage of different heights and quality (Kuiters et al.
Anadromous threespine stickleback were trapped in nine lakes and streams (5% of sites sampled) and seven of these nine sites also contained resident freshwater threespine stickleback, giving rise to sympatric species pairs (Appendix 1).
Gastrointestinal helminths from six species of frogs and three species of lizards, sympatric in Para State, Brazil.
Bobcats and coyotes are sympatric throughout most of their ranges, and, although competition may occur between the species, it has been difficult to evaluate and likely varies among areas and with availability of prey (Palomares and Caro, 1999).
