These "outlying ridge species" are hypothesized to be relictual taxa that became extinct along the main Andean chain but persist due to lack of competition in the relatively depauperate avian communities on outlying ridges (Terborgh and Weske 1975, Fitzpatrick et al.
10) in north-central Nebraska contains disjunct and relictual elements of both plant and animal species that were probably widespread during cooler, wetter Pleistocene and Holocene times and that today occur well to the west, north, or east.
These several relictual populations collectively suggest a wider distribution of the species to the north in the past, during a hypsithermal period, and a partial withdrawal during the current hypothermal period, occurring not long enough ago to have permitted subsequent taxonomic differentiation.
In addition, a small relictual population was known to inhabit the extreme southwestern corner of the state, although recent attempts to locate this population have failed (Fig.
These unexpected findings suggest that liverworts contain a number of relictual taxa that may well hold even more clues to the evolution of plant form.
Oases of the peninsula are relictual habitats that act as refuges for mesic species and that attract fauna of the surrounding desert (Rodriguez-Estrella et al.
Genetic differentiation of relictual populations of Alsophila spinulosa in southern China inferred from cpDNA trnL-F noncoding sequences.
The single specimen from Hardin County was taken in 1902 and represents the relictual subspecies M.
Itea has generally been viewed as a classic eastern North American-eastern Asian disjunct taxon (Li, 1952; Wu, 1983; Wen, 1999; Guo & Ricklefs, 2000), with evidence from fossils suggesting that its geographical distribution was likely relictual from a Paleogene to Neogene Northern Hemisphere distribution that included at least Europe and eastern North America (e.
The question arises as to whether occupation of the Guadalupe Mountains and other areas of the region is a result of post-Pleistocene colonization or of relictual survival from the Pleistocene.
We hypothesize that the rodent community that presently characterizes sand shinnery oak habitats is a relictual subset of the original mid-grass prairie rodent fauna that was sufficiently generalized to survive the transition.
