An Evaluation of Collaborative Salmon Fishery Management in Prince William Sound, Alaska

Creator:: Sheridan, Thomas M.
Abstract:: Collaborative decision-making is often promoted as a means to achieve socially acceptable and enduring solutions to natural resource management issues, and one that holds promise for resolving “wicked” problems. However, success rates for implementation of collaborative recommendations are unknown. This paper explores challenges to collaborative salmon fishery management in Prince...

Human Alteration of a Neotropical Landscape Drives Long-term Changes in its Forest Bird Communities

Creator:: Curtis, Jenna R.
Abstract:: Human alteration of natural landscapes leads to biodiversity loss, often from a combination of area effects and fragmentation effects. Smaller habitat patches support fewer species than large ones and incur additional consequences from isolation. Efforts to preempt biodiversity loss from insular habitat fragments are complicated by individualistic species responses and...

Abstract:: Florida is a hotspot for nonindigenous fishes with over 30 species established, although few of these are small-bodied species. One hypothesis for this pattern is that biotic resistance of native species is reducing the success of small-bodied, introduced fishes.
