Comparison Of Fish Assemblages In Restored And Natural Mangrove Habitats Along An Urban Shoreline, Joseph R. Peters, Lauren A. Yeager, Craig A. Layman

Environmental Science and Management Faculty Publications and Presentations

The installation of living shorelines is one strategy used to ameliorate habitat degradation along developed coastlines. In this process, existing hard structures, such as sea walls and riprap revetments, are supplemented with habitat forming species, e.g., oysters and mangrove trees, to improve habitat quality and function. Shoreline restorations in Biscayne Bay, Florida, USA, often utilize red mangroves, Rhizophora mangle (Linneaus, 1753), in addition to riprap revetments, to help stabilize the shoreline. This riprap-mangrove habitat provides structure for marine organisms to utilize and is believed to improve shoreline habitats in areas previously cleared of mangroves. We examined whether habitat provisioning was …

Modeling Predator Habitat To Enhance Reintroduction Planning, Shiloh Michael Halsey, William J. Zielinski, Robert M. Scheller

Environmental Science and Management Faculty Publications and Presentations

Context

The success of species reintroduction often depends on predation risk and spatial estimates of predator habitat. The fisher (Pekania pennanti) is a species of conservation concern and populations in the western United States have declined substantially in the last century. Reintroduction plans are underway, but the ability of the species to establish a selfsustaining population is affected by predation from its primary predator, the bobcat (Lynx rufus).

Objectives

To develop a habitat model that incorporates both habitat of the focal species and the spatial patterning of predator habitat. To locate areas of densely aggregated habitat that would be suitable …
