Global patterns in biodiversity

This work states that the distribution of biodiversity across the Earth can be described in terms of a relatively small number of broad-scale spatial patterns, and theory is developing rapidly, improving in its internal consistency, and more readily subjected to empirical challenge.
Measuring beta diversity for presence–absence data
Summary 1. Little consensus has been reached as to general features of spatial variation in beta diversity, a fundamental component of species diversity. This could reflect a genuine lack of simple…
Functional diversity: back to basics and looking forward.
It is suggested that non-significant results have a range of alternate explanations that do not necessarily contradict positive effects of functional diversity, and areas for development of techniques used to measure functional diversity are suggested.
Functional diversity (FD), species richness and community composition
A means for quantifying functional diversity that may be particularly useful for determining how functional diversity is related to ecosystem functioning is proposed, defined as the total branch length of a functional dendrogram.

The process and the technical background to the IUCN Red List system is described, which was designed to measure the symptoms of extinction risk, and uses 5 independent criteria relating to aspects of population loss and decline of range size.
Effectiveness of the global protected area network in representing species diversity
It is shown that the global network of protected areas is far from complete, and the inadequacy of uniform—that is, ‘one size fits all’—conservation targets is demonstrated, in the first global gap analysis assessing the effectiveness ofprotected areas in representing species diversity.

Findings for insects based on published upper and lower lethal temperature data provide some support for the physiological tolerance assumption associated with Rapoport's rule, but highlight the need for coupled data on species tolerances and range size.
Geographic gradients in body size: a clarification of Bergmann's rule
1997 marked the sesquicentenary of the publication by Carl Bergmann of the observation that, in general, large-bodied animal species tend to live further north than their small-bodied relatives. This…
