ENVIRONMENTAL VERSUS SOURCE POOL CONSTRAINTS ON AN URBAN ZOOPLANKTON METACOMMUNITY
Many sustainability plans and management practices reflect the need to conserve biodiversity, yet once these plans are implemented, the ecological consequences remain uncertain. By understanding how management practices affect local environmental factors and dispersal in a region, ecologists can gain a better understanding of the implications for management choices. Our goal was to determine how the interaction between spatial variation in habitat quality in algal management of urban ponds and dispersal shape biodiversity at multiple spatial scales. A twelve-week mesocosm study was conducted where pond management and dispersal were manipulated to determine how spatial variation in habitat and source pool constraints on dispersal influence zooplankton metacommunities. We hypothesized that dispersal from managed or unmanaged source pools will lead to shifts in community composition and local management practices will act as an environmental filter, reducing beta diversity between managed ponds. Our results revealed that the source pool of dispersers led to community divergence and that local management practices significantly reduced compositional turnover of zooplankton among ponds. The results of this study suggest that sustainability and management plans may have complex, deleterious effects on biodiversity both within and across local habitats.
