Despite its theoretical relationship, the effect of body size on the performance of species distribution models (SDM) has only been assessed in a few studies of terrestrial taxa. We aim to assess the effect of body size on the performance of SDM in river fish....

Microbes, with their vast metabolic capabilities and great adaptability, occupy almost every conceivable ecological niche on Earth. Thus, could they survive in oligotrophic deionized (DI) water? Observations of white cauliflower-like lumps and black specks in salt...

Understanding how and why individual movement translates into dispersal between populations is a long-term goal in ecology. Movement is broadly defined as “any change in the spatial location of an individual”, whereas dispersal is more narrowly defined as a movement...

We repeatedly sampled eight sites on the Crooked River in British Columbia’s Arctic watershed for adult and nymph mayflies (Ephemeroptera) over the course of two years. Using taxonomic keys and DNA-barcoding we report eight new species records for the province....
