Space for time substitution in dryland freshwater ecosystems


The main issues to be addressed will be the effects of climate change, eutrophication, and salinization on biodiversity patterns on a global perspective, besides the effects of water level reductions in the maintenance of species richness and ecosystems services. However, how to sample data in temporary ecosystems? 

One alternative is to use a comparative analysis of ecosystems in a space-for-time substitution approach to predict the consequences of rainfall reduction on environmental and biological variables (Blois et al. 2013).

In this case, three main perspectives need to be considered: Monitoring sites, experimental approach and paleolimnology.
