Ecological Niches, Species Distributions, And Biogeographic Processes In Rodents On Neotropical Sky Islands
… in two species of rodents restricted to the sky islands of Costa Rica and western Panama: Reithrodontomys creper and Nephelomys devius. Overall, results revealed how, despite sharing similar distribution patterns, niche differences in these species resulted in idiosyncratic responses to past …

Competitive status of red spruce (Picea rubens) and Fraser fir (Abies fraseri) at ecotonal transitions in southern Appalachian sky islands
Southern Appalachian spruce-fir sky islands are globally threatened, boreal relict forests where red spruce (Picea rubens) and Fraser fir (Abies fraseri) are dominant. Fraser fir dominates at the highest elevations with spruce-fir and spruce-dominated stands at middle elevations and hardwoods …

Faunal turnover between east and southern African terrestrial vertebrates: is Malawi the geographical break?
… uncontrolled fires are threatening the montane ‘sky islands’ population, thus compromising the conservation of the fauna and important evolutionary distinct units.

Reassessment of species limits and diversification process in the Cape grass genus Ehrharta Thunb
… role in driving diversification in the montane “sky islands” of the GCFR, potentially resulting in cryptic species. This work seeks to test the relative importance of ecological versus non-ecological processes in powering speciation at different elevations in the GCFR, and to assess the existence …

Extent And Distribution Of Montane Riparian Zone Vegetation And Representation In Protected Areas In The Sky Island Region Of The Southwestern United States
The Sky Island region of the southwestern United States hosts some of the richest biodiversity anywhere in the world. In the mountain ranges of the Sky Islands, most vertebrate biodiversity is dependent on riparian areas for all or some of their life cycles. Riparian vegetation is threatened by …

More than meets the eye: A taxonomic revision of the Nearctic species in the eye-gnat genus Amiota Loew (Diptera: Drosophilidae)
<p>Thorough biotic inventories are still needed even in families as seemingly well-studied as fruit flies (Diptera: Drosophilidae). Drosophilidae have had an outsize effect on the history of biology because of their pivotal role in the study of genetics, development, and evolution. Even with more …
