Thermal niche, large-scale movements and implications of climate change for a critically endangered marine vertebrate
Climate change is expected to have a number of impacts on biological communities including range extensions and contractions. Recent analyses of multidecadal data sets have shown such monotonic shifts in the distribution of plankton communities and various fish species, both groups for which there i...
