TL;DR: In this article, the effects of animal tracks and fecal pellet production on the critical entrainment velocity of marine sediments were examined experimentally and the results showed that animal tracking doubled boundary roughness and decreased critical entraining velocity by 20%.

TL;DR: In this paper, a more general formulation capable of dealing with all three types of processes in concert, a simple, discrete-time Markov model is generated, which deals explicitly only with particulate and not liquid phases.
