Dynamics of a benthic-drift model for two competitive species

摘要: Abstract Population dynamics of multiple interactive species in rivers and streams is important river/stream ecology. In this paper, we consider a model for two competitive living river environment where the populations grow compete benthic zone disperse drifting water zone. We establish threshold conditions persistence extinction obtain existence positive steady state under conditions. also numerically investigate influences factors, such as advection rates, diffusion length, competition transfer spatial heterogeneity on species.
