Objective:

There are five objectives:

  1. Work with environmental managers and stakeholders to explore different scenarios for land use planning, development of coastal areas, habitat restoration, or other management issues in the context of climate change and invasive species. 
  2. Conduct mesocosm experiments testing links between climate change and landuse in altering the ability of invasive species to affect native communities.
  3. Conduct field experiments to assess temporal and/or spatial scales of potential efforts needed to effectively manage invasive species. Goals include testing whether marina-scale or larger scale eradication are needed to control future invasions and the timing in which management of invasive species is most effective.
  4. Conduct field experiments examining survival of key predators of invasive species in areas of different land use. If predators are limiting invasions of open coast habitats, it is important to understand what limits the distribution of these critical species.
  5. Develop predictive models to assess alternative management strategies. Focus will be placed on integrating management needs with ecological predictions that allow managers to evaluate multiple stressors at different temporal and spatial scales in different types of coastal systems.

Progress Summary:

To date, we have: 

  • Conducted a project evaluation and planning workshop to review progress and develop strategies for future modeling efforts and their integration.
  • Participated in and presented our preliminary results at an EPA Program Workshop in Seattle, WA.
  • Established a project Management Advisory Board consisting of the following individuals: Mark Tedesco (Director, U.S. EPA Long Island Sound Office), Paul Stacey (Director of Planning and Standards, Bureau of Water Protection and Land Use, CT Department of Environmental Protection), Gary Wikfors (Scientist, NOAA-NMFS, Milford, CT), Adam Whelchel (Director of Conservation Science, The Nature Conservancy, CT Chapter), Beth Doran (Director, Long Island Sound Resource Cener, CT DEP), Susan McNamara (Executive Director, Long Island Sound Foundation).  
  • Conducted a workshop with various Long Island Sound resource managers and stakeholders – August 4, 2008 – to discuss management priorities and needs; broaden network with the managers/stakeholders; discuss project goals and outputs and how they can assist with management goals
  • Met with shellfish, planning and conservation commissions – Towns of Groton, New London, Stonington, East Lyme/Waterford – discuss local management needs and goals of the project.
  • Outreach activities related to the project included: (a) Interviews/articles: Connecticut National Public Radio, New London Day, Boston Globe; (b) featured segment on AquaKids Episode 18 (distributed to ~80M households nationwide; aired in Connecticut 24 Jan 2009, aired nationally week of 19 Jan 2009).
  • Conducted a pilot study to conduct experiments examining the interactions of elevated seawater temperatures on the survival and growth of native and non- native invertebrate species.

  • Conducted a pilot study to assess the effectiveness of marina-scale or larger scale eradication of non-native species as a method for controlling future invasions.
  • Began expanding the spatially-explicit, hydrographic model developed by Dr. John Hamilton, a postdoctoral fellow with the PI. The model is being modified to examine a larger geographic areas and to include a greater diversity of species life-history characteristics that encompass the key threshold species and communities.   

Future Activities:

Present efforts will continue and be expanded. Activities planned include:

  • Conduct a Management Advisory Board workshop to evaluate progress and plan project laboratory and field experiments and modeling efforts for Year 2.
  • Conduct a large-scale controlled mesocosm experiment designed to examine the effects of elevated seawater and nutrient additions on benthic assemblages of native and non-native invertebrates associated with eelgrass, sand and rocky habitats.
  • Conduct a series of field experiments in areas of different coastal land use (e.g., residential, industrial, ‘pristine’) to assess the effectiveness of different predator guilds (e.g., crabs, snails, seastars, amphipods, shrimp) in controlling the growth and survival of native and non-native fouling assemblages.
  • Conduct a pilot study to assess the effectiveness of marina-scale or larger-scale eradication of non-native species as a method for controlling future invasions.

The results will be presented at one or more international scientific meetings. At least two presentations will be given at the Benthic Ecology Meetings in Willmington, NC, and two at the 3rd International Invasive Seasquirt Conference in Woods Hole, MA.
