‘Biodiversity offsetting’ aims to address the residual negative environmental impacts of human development. It's goal is to achieve No Net Loss (NNL), and preferably a Net Gain of biodiversity attributes between development and offset sites. Biodiversity offsetting suffers from a lack of ‘proof of concept’, as little work has been done to critically test the ecological efficacy of offsetting practices. Offsetting of stream eco...

Summary We sought to test whether stream bacterial communities conform to Rapoport's Rule, a pattern commonly observed for plants and animals whereby taxa exhibit decreased latitudinal range sizes closer to the equator. Using a DNA sequencing approach, we explored the biogeography of biofilm bacterial communities in 204 streams across a ∼1000 km latitudinal gradient. The range sizes of bacterial taxa were strongly correlated w...

Aim The extent to which bacterial communities exhibit biogeographic patterns in their distribution remains unclear. We examined the relative influence of factors including geographic distance, latitude, elevation and catchment land use on the distribution and taxon richness of stream bacterial communities across N ew Z ealand. Location Bacterial communities were collected from biofilm growing on submerged rocks in 244 streams....
