Consider the two-species phytoplankton competition model with equal advection rates $\alpha_1=\alpha_2=\alpha$, equal growth functions $g_1=g_2$, equal additional diffusion paramet…

Consider the two-species river competition system with diffusion rates $d,D>0$, common advection rate $\alpha>0$, growth rate $r(x)$, upstream flux boundary conditions, and zero Di…

Assume $1\le k<n$, assumptions $\mathrm{(A2)}$–$\mathrm{(A4)}$ hold, $(d_{ij})$ is ideal-free on patches $1\le i\le k$ and satisfies $d_{ij}=0$ whenever $i>k$ or $j>k$, and…
