Answer to Question #111185 in Evolution for Jaime Cruz-Vega

Question

List one distinct impact on freshwater macroinvertebrate communities (species, species richness, densities) likely to result from reduced meltwater input to freshwater mountain streams if global warming continues to reduce the number and extent of glaciers.?
Did the paper by Brown et al. directly measure decreased meltwater resulting from shrinking glaciers caused by climate change (specifically global warming)?

Answer 1

Changes in habitat conditions

The paper by Brown et al. directly measured decreased meltwater resulting from shrinking glaciers caused by climate change (specifically global warming) and by their data sets, they were able to show significant responses to declining glacier cover for diatoms, which wich are the basic freshwater producers.
