In this Opinion piece, I argue that the dynamics of viruses and the cellular immune response depend on the body size of the host. I use allometric scaling theory to interpret observed quantitative differences in the infection dynamics of lymphocytic choriomeningitis...

Here we investigate relationships between NDVI, Biomass, and Leaf Area Index (LAI) for six key plant species near Barrow, Alaska. We explore how key plant species differ in biomass, leaf area index (LAI) and how can vegetation spectral indices be used to estimate...

Dispersal capacity plays a fundamental role in riverine benthic invertebrates’ colonization of new habitats that emerge following flash floods or restoration. However, an appropriate measure of dispersal capacity for benthic invertebrates is still lacking. Dispersal...
