Weeds of Hawaii’s lands devoted to watershed protection and biodiversity conservation: Role of biological control as the missing piece in an integrated pest management strategy
Arthur C. Medeiros, L.L. Loope
2011, Conference Paper, Center for Invasive Species and Ecosystem Health
Despite Hawaii’s reputation as an extinction icon, significant biological resources remain, especially in watersheds, natural areas, and specialized edaphic sites (e.g., lava dry forest, coastal). While direct habitat destruction by humans continues, human-facilitated biological invaders are currently the primary agents of continuing degradation. The ability of invasive plants to have...

T. J. Mozdzer, M. Kirwan, K. J. McGlathery, J. C. Zieman
2011, Marine Ecology Progress Series (433) 43-52
The smooth cordgrass Spartina alterniflora is the foundation species in intertidal salt marshes of the North American Atlantic coast. Depending on its elevation within the marsh, S. alterniflora may be submerged for several hours per day. Previous ecosystem-level studies have demonstrated that S. alterniflora marshes are a net sink for...
No population genetic structure in a widespread aquatic songbird from the Neotropics
Carlos Daniel Cadena, Natalia Gutierrez-Pinto, Nicolas Davila, R. Terry Chesser
2011, Molecular Phylogenetics and Evolution (58) 540-545
Neotropical lowland organisms often show marked population genetic structure, suggesting restricted migration among populations. However, most phylogeographic studies have focused on species inhabiting humid forest interior. Little attention has been devoted to the study of species with ecologies conducive to dispersal, such as those of more open and variable environments...
