The elevational patterns of diversity for plants and animals have been well established over
the past century. However, it is unclear whether there is a general elevational distribution …

The abiotic and biotic gradients on mountains have enormous potential to improve our
understanding of species distributions, species richness patterns and conservation. Here we …

Worldwide agriculture is one of the main drivers of biodiversity decline. Effective
conservation strategies depend on the type of relationship between biodiversity and land …

Abstract Synopsis In 1967 Daniel Janzen published an influential paper titled “Why
Mountain Passes Are Higher in the Tropics.” Janzen derived a simple climatic-physiological …

The elevational gradient in plant and animal diversity is one of the most widely documented
patterns in ecology and, although no consensus explanation exists, many hypotheses have …

A major focus of research in spatial ecology over the past 25 years has been to understand
why the number of species varies geographically. The most striking, and perhaps best …

Mountains, especially in the tropics, harbour a unique and large portion of the world's
biodiversity. Their geographical isolation, limited range size and unique environmental …

Geographic variation of species richness is strongly correlated with environmental gradients.
However, random arrangement of species distributions within a bounded domain can also …

Aim Elevational gradients offer an outstanding opportunity to assess factors determining
patterns of species richness, but along single transects potential explanatory factors often …

Tropical montane species are characterized by narrow elevational distributions. Recent
perspectives on mechanisms maintaining these restricted distributions have emphasized …
