| 요약 | Metapopulations occupy spatially divided habitats and understanding how that fragmentation affects their survival, growth, dispersal, and persistence is critical to their conservation. Researchers in many sub-fields of ecology and evolutionary b |
| 요약 | I invented the Metapopulation Microcosm Plate (MMP) to overcome these drawbacks. This device resembles a 96-well microtiter plate |
| 요약 | In Chapter One, I first demonstrate that bacterial travel time is significantly faster through MMP dispersal corridors that are shorter, but is unaffected by corridor vertical position within the plate. Thus, MMPs satisfy the necessary assumptio |
| 요약 | In Chapter Two, I used MMPs to explore how recolonization and recovery after subpopulation extinction differs in metapopulations in which the dispersal corridors have different spatial arrangements. Some metapopulations have corridors spread rel |
| 요약 | Finally, for Chapter Three I conducted an experiment to test whether metapopulations with heterogeneous corridor arrangements recover more slowly from extinctions targeted at high connectivity subpopulations than random extinctions in low connec |
| 요약 | This work demonstrates that MMPs can be used to test the assumptions of metapopulation theory, especially those involving large numbers of subpopulations and dispersal corridors. I have shown that metapopulations with heterogeneous corridor arra |
