Spatial modelling of temporal dynamics in stream fish communities under anthropogenic change

Understanding temporal changes in aquatic communities are essential to address the freshwater biodiversity crisis. In particular, it is important to understand the patterns and drivers of spatial variation in local community dynamics, generalizing temporal trends from discrete locations to entire landscapes that are the main focus of management. Here, we present a framework for producing spatially continuous views of community dynamics, focusing on stream fish affected by hydropower development.

The study was conducted in NE Portugal, in the River Sabor watershed (N41°09′–42°00′, W7°15′–6°15′;
