Creator:: Reusser, Deborah A.
Abstract:: Nonindigenous species are a major threat to the ecological integrity and biodiversity of marine and estuarine ecosystems. To become a successful invader, species must pass through four phases: (1) survive transport, (2) survive release, (3) establish a population, and (4) expand their range. To better understand these processes, an integrated...

Abstract:: Wetland restoration success in attaining wildlife conservation goals can be confounded by the presence of multiple biological invaders. Wetland management activities typically target invasive plants, but bottom-up responses of higher trophic levels in novel communities are difficult to predict. We surveyed plant and amphibian assemblages at 26 sites enrolled in...

Creator:: Marek, Charlene Marie
Abstract:: Drosophila suzukii was a known pest of berries, grapes, and stone fruits in East Asia for almost a century. Yet in recent years it has successfully migrated throughout the United States, Mexico, and Europe due to globalized fruit trade. The invasive success of D. suzukii is causing unrest for fruit...

Creator:: Hall, Kim M.
Abstract:: The spatial and temporal behavior of invasive species spread implies that optimal management strategies involve decisions over space and time. Dispersal and propagule pressure are two primary drivers of the spatial-temporal ecological process of species invasion. In the case of riparian communities, stream flow drives the dispersal of vegetation propagules....

Creator:: Kovski, Nicole
Abstract:: In the case of lake management for recreational use, policy makers often face a balancing act. They must maintain both the ecological quality of sites and the welfare of recreationists. In Wisconsin's Northern Highland Lake District, recreational boaters inadvertently transport aquatic invasive species between lakes. Economic models of boater demand...

Creator:: Alkaee Taleghan, Majid
Abstract:: This work is inspired by problems in natural resource management centered on the challenge of invasive species. Computing optimal management policies for maintaining ecosystem sustainable is challenging. Many ecosystem management problems can be formulated as MDP (Markov Decision Process) planning problems. In a simulator-defined MDP, the Markovian dynamics and rewards...

Creator:: Wellons, Kathryn C.
Abstract:: Great Lakes coastal wetland communities are threatened by the impacts of invasive plants on ecosystem function and biodiversity. What allows invasive plants to become dominant in invaded communities can be hard to define and context-dependent. Traits associated with invasion success in wetland systems – rapid vegetative growth, competitive superiority in...
