Geomorphic controls on elevational gradients of species richness.
Elevational gradients of biodiversity have been widely investigated, and yet a clear interpretation of the biotic and abiotic factors that determine how species richness varies with elevation is still elusive. In mountainous landscapes, habitats at different elevations are characterized by different areal extent and connectivity properties, key drivers of biodiversity, as predicted by metacommu...
متن کاملElevational Gradients in Species Richness
The abiotic and biotic gradients on mountains have enormous potential to improve our understanding of species distributions, species richness patterns and conservation. Here we describe how abiotic factors change with elevation, how flora and fauna respond to these changes and how elevational species richness patterns have been studied to uncover drivers of biodiversity. There are four main tre...
متن کاملPatterns of reptile and amphibian species richness along elevational gradients in Mt. Kenya.
Faunal species richness is traditionally assumed to decrease with increasing elevation and decreasing primary productivity. Species richness is reported to peak at mid-elevation. This survey examines the herpetofaunal diversity and distribution in Mt. Kenya (central Kenya) by testing the hypothesis that changes in species richness with elevation relate to elevation-dependent changes in climate....
متن کاملThe mid-domain effect applied to elevational gradients: species richness of small mammals in Costa Rica
The striking ecological changes that occur along elevational gradients drew the attention of early researchers, such as Darwin (1839, 1859), von Humboldt (1849), Wallace (1876, 1878) and Merriam (1890). Although latitudinal gradients in species richness have received more attention, elevational patterns have been addressed in the literature recently for various taxa. A recent issue of Global Ec...
متن کاملPatterns of ant species richness along elevational gradients in an arid ecosystem
Aim In this study, we examine patterns of local and regional ant species richness along three elevational gradients in an arid ecosystem. In addition, we test the hypothesis that changes in ant species richness with elevation are related to elevation-dependent changes in climate and available area. Location Spring Mountains, Nevada, U.S.A. Methods We used pitfall traps placed at each 100-m elev...
