stream macroecology

Streams and rivers are the most biodiverse ecological systems per unit area.

I use publicly available data collected by professional researchers, community scientists, and government agencies to assess 3 predicted ecological responses to global change (and exceptions to these predictions):

biodiversity

• Shifts in species ranges toward higher elevations and (absolute) latitudes

body size

• Shifts in body size toward smaller-bodied individuals

phenology

• Shifts in seasonal life history/life cycle events toward earlier timing
