| marbled murrelet nest predation risk in managed forest landscapes: dynamic fragmentation effects at multiple scales. | the effects of forest fragmentation on bird populations have been studied primarily as static phenomena. yet when forests are allowed to regenerate, local edge contrast and landscape matrix composition change with time, and we would expect fragmentation effects to change accordingly. describing this process is critical for the conservation of avian species sensitive to forest fragmentation, including the marbled murrelet (brachyramphus marmoratus), a seabird threatened by ongoing harvest of old- ... | 2009 | 19688934 |
