Restoring indigenous names in taxonomy.

Some pillars of scientific practice appear immutable. We propose that one of these needs more thorough consideration and modification: this being the long-standing emphasis in nomenclature for first published names over pre-existing indigenous names, in accepting species epithets. We suggest that biologists re-evaluate this practice, in the context of a current more general re-evaluation of indigenous knowledge.

What is the form of the productivity-animal-species-richness relationship? A critical review and meta-analysis.

The nature of the relationship between productivity and species richness has remained controversial for at least two decades. Recently authors have favored the suggestion that the form of this relationship is highly variable and scale dependent. However, this conclusion is not universally accepted.

Latitude, elevation and the tempo of molecular evolution in mammals.

Faster rates of microevolution have been recorded for plants and marine foraminifera occupying warmer low latitude environments relative to those occurring at higher latitudes. By contrast, because this rate heterogeneity has been attributed to a relationship between thermal habit and mutagenesis via a body temperature linkage, it has been assumed that microevolution in mammals should not also vary systematically with environmental temperature. However, this assumption has not previously been empirically examined.

Slower tempo of microevolution in island birds: implications for conservation biology.

Whether microevolution on small islands differs from that on larger landmasses is a key question in biology with substantial implications for species conservation. However, due to the difficulties faced in producing adequately replicated samples and in controlling for confounding variables, prior attempts to examine evolutionary questions relating to habitat area and population size have produced equivocal results. Here we show, using experimental design criteria that reduce the potential for such confounding, that bird species on larger landmasses have higher rates of molecular evolution.

The influence of productivity on the species richness of plants: a critical assessment.

Despite much scrutiny the relationship between productivity and species richness remains controversial, and there is little agreement about causal processes. We present the results of a survey of 159 productivity-plant species richness (P-PSR) relationships from 131 published studies. We critically assessed each study with respect to experimental design and for the appropriateness of the surrogates used for productivity.

Energy and the rate of evolution: inferences from plant rDNA substitution rates in the western Pacific.

In this study, we compare rDNA substitution rates for a group of closely related plant species in the western Pacific that exist in different biomes. The results of this comparison indicate higher rates of substitution for species living in habitats with greater biologically available energy. We interpret that finding as potentially important in understanding evolution because of its implication that substitution rate may be a function of biologically available energy and its correlate, productivity.
