LYONS, S.K.; University of California, Santa Barbara: The effects of elevation on two aspects of local community structure of late Pleistocene mammals Previous work examining the effect of elevation on species responses to climate change has shown that elevation has an ameliorating effect on range shifts. Because vegetation zones shift with elevation as climate changes, […]

NAVAS, C.A.; Universidade de S�o Paulo: Physiology of high-elevation amphibians: relationships with behavior and ecological challenge A well supported macro-ecological trend is the reduction of biological diversity along altitudinal gradients. Although tropical amphibians conform to this pattern, this taxon exhibits various species, genera and families that are significantly represented at elevations higher than 3000 m. […]

HAMMOND, KA*; CHMURA, CA; RUSSELL, GA; ORTIZ, S; UC. Riverside and White Mountain Research Station: Genetic and phenotypic responses of small mammals to life at high altitudes Because of their small size and high energy demands, small mammals living at high altitude face several important challenges. Energy demands are greater because of low ambient temperatures, […]

WAKE, D; Univ. of California, Berkeley: Effects of altitudinal gradients on salamander biodiversity in tropical America Salamanders are abundant in Middle America and in Colombia but almost nowhere else in the tropics. The areas of greatest abundance are characterized by extreme topographic diversity and by unstable and shifting geology. Elevational transects from Veracruz, Mexico, to […]
