A coupled vegetation/sediment transport model for dryland environments
Sign Up to like & getrecommendations! Published in 2017 at "Journal of Geophysical Research"
DOI: 10.1002/2016jf004096
Abstract: Dryland regions are characterized by patchy vegetation, erodible surfaces, and erosive aeolian processes. Understanding how these constituent factors interact and shape landscape evolution is critical for managing potential environmental and anthropogenic impacts in drylands. However,… read more here.

DOI: 10.1016/j.jaridenv.2019.104037
Abstract: Abstract The growth-rate hypothesis (GRH) says that fast-growing organisms have relatively high P content and lower N:P ratios because they need more P-rich ribosomal RNA (rRNA) to fuel increased protein-synthesis. However, there is a lack… read more here.
