Temporal variations in the environment may function as disturbances that affect population processes and change the structure and composition trajectories of communities. The presence of refuges may buffer such variations and also support the recovery of communities after disturbances. In this study, we tested the effect of temporary pools as seasonal refuges for the ichthyofauna in upland forest...
For species living in highly variable environments, the ability to perceive and respond to environmental cues by moving into favorable habitats should convey evolutionary advantages. Here we examined the spatial dynamics of an Amazonian pencil fish species that shows seasonally varying use of stream channel and temporary pool habitats. We hypothesized that movement into the pools should be driven...
