| divergence in sink contributions to population persistence. | population sinks present unique conservation challenges. the loss of individuals in sinks can compromise persistence; but conversely, sinks can improve viability by improving connectivity and facilitating the recolonization of vacant sources. to assess the contribution of sinks to regional population persistence of declining populations, we simulated source-sink dynamics for 3 very different endangered species: black-capped vireos (vireo atricapilla) at fort hood, texas, ord's kangaroo rats (dip ... | 2015 | 26032147 |
