A global analysis of elevational diversity trends for nonvolant small mammals revealed a clear pattern of mid-elevational peaks in species richness. Fifty-six data sets were used to test the predictions of a null model (the mid-domain effect) and climatic hypotheses. Very few data sets fit entirely within the predictions of the null model, and the average predictive power of the null model was low. Regional (gamma) diversity fit the null model better than did local (alpha) diversity. Diversity… Expand

Aim  Latitudinal- and regional-scale studies of reptile diversity suggest a predominant temperature effect, unlike many other vertebrate richness patterns which tend to be highly correlated with bothExpand
Global analysis of bird elevational diversity
Aim Elevational gradients distributed across the globe are a powerful test system for understanding biodiversity. Here I use a comprehensive set of bird elevational gradients to test the main driversExpand
Environmental and geometric drivers of small mammal diversity along elevational gradients in Utah
TLDR
It is suggested that commonality in the pattern of species richness, even among elevational gradients with a similar biogeographic history and fauna, cannot be attributed to a simple universal explanation, and drivers of diversity may vary seasonally. Expand
Area and mammalian elevational diversity.
TLDR
This work tests the species-area effect and spatial constraint using regional diversity patterns for mammals along 34 elevational gradients along 34 degrees S-40.4 degrees N latitude to see if both hypotheses can be eliminated as primary drivers of elevational diversity. Expand

SPECIES RICHNESS AND ABUNDANCE OF SMALL MAMMALS ALONG AN ELEVATIONAL GRADIENT OF A MEDITERRANEAN MOUNTAIN
TLDR
Species richness increased from the warm and relatively dry lowlands to the colder and moister uplands, with the highest levels of species richness being found at the divide between the Mediterranean and Eurosiberian climatic zones and plant communities. Expand
Global variation in elevational diversity patterns
TLDR
This work compiled data from 443 elevational gradients involving diverse organisms worldwide to investigate how elevational diversity patterns may vary between the Northern and Southern hemispheres and across latitudes and shows that most Elevational diversity curves are positively skewed. Expand

Small mammal diversity along elevational gradients in the Philippines: an assessment of patterns and hypotheses
TLDR
Twelve hypotheses concerning patterns of diversity along elevational gradients, plus the null hypothesis, are evaluated and there is strongest support for the hypotheses that diversity is correlated with annual rainfall, with total abundance of individuals in the community, with food resource diversity, with areas of reduced competition from other organisms, and with areas characterized by high rates of speciation.

TLDR
The geometric constraints of montane topography appear to influence the diversity pattern of small mammals, although climatic conditions including an intermediate rainfall and temperature regime, and distance from the persistent cloud cap also are correlated with the pattern of species richness.

TLDR
Elevational turnover rates and numbers of shared species between zones suggested that the hump‐shaped pattern relects geometric constraints (as predicted by the null model) imposed by the narrow span of the gradient, and it is suggested that midelevational zones may represent sink habitats. Expand
Nonbiological Gradients in Species Richness and a Spurious Rapoport Effect
TLDR
It is shown that "nonbiological" gradients in species richness arise inevitably from the assumption of a random latitudinal (or elevational) association between the size and placement of species' ranges, and that a spurious Rapoport effect can be caused by sampling bias alone. Expand
Contrasting patterns of elevational zonation for birds and mammals in the Andes of southeastern Peru
TLDR
The pronounced contrasts between bats and mice, and the generally intermediate character of avian patterns, suggest that future analyses might profitably partition birds into finer, more homogeneous groups of historically and/or ecologically similar species. Expand
