Water beetles from the Bokkeveld plateau: A semi-arid hotspot of freshwater biodiversity in the Northern Cape of South Africa
© 2017 Magnolia Press.The Bokkeveld Plateau in the Northern Cape of South Africa supports a complex transition zone between the fynbos and succulent karoo biomes on the margins of Namaqualand. A combination of regular ...
Deeper knowledge of shallow waters: reviewing the invertebrate fauna of southern African temporary wetlands

The effect of geographical scale of sampling on DNA barcoding.
Eight years after DNA barcoding was formally proposed on a large scale, CO1 sequences are rapidly accumulating from around the world. While studies to date have mostly targeted local or regional species assemblages, the ...
Oxygen-limited thermal tolerance is seen in a plastron-breathing insect and can be induced in a bimodal gas exchanger.
Thermal tolerance has been hypothesized to result from a mismatch between oxygen supply and demand. However, the generality of this hypothesis has been challenged by studies on various animal groups, including air-breathing ...

Assessing the congruence of thermal niche estimations derived from distribution and physiological data. A test using diving beetles.
A basic aim of ecology is to understand the determinants of organismal distribution, the niche concept and species distribution models providing key frameworks to approach the problem. As temperature is one of the most ...
