Wetland Ecosystem Response To Hydrologic Restoration And Management: The Everglades And Its Urban- Agricultural Boundary (Fl, Usa), Pamela L. Sullivan, Evelyn E. Gaiser, Donatto Surratt, David T. Rudnick, Stephen E. Davis, Fred H. Sklar
Wetland Ecosystem Response To Hydrologic Restoration And Management: The Everglades And Its Urban- Agricultural Boundary (Fl, Usa), Pamela L. Sullivan, Evelyn E. Gaiser, Donatto Surratt, David T. Rudnick, Stephen E. Davis, Fred H. Sklar

Wetland restoration success depends on understanding ecohydrological complexities in addition to the historical extent and legacies of past modifications. Restoration effectiveness in the Florida Everglades has been studied for several decades. We focused this special issue on the effects of hydrologic restoration in the southeastern Everglades, as this region provides a model for understanding wetland and estuarine response to management and restoration along an urban-agricultural-wetland boundary. We synthesize several decades of interdisciplinary wetland ecosystem restoration studies examining the influence of hydrologic and biogeochemical changes on spatial and temporal patterns of ecosystem structure and function. Our goal is to improve restoration …
Distribution Of Diatoms Along Environmental Gradients In The Charlotte Harbor, Florida (Usa), Estuary And Its Watershed: Implications For Bioassessment Of Salinity And Nutrient Concentrations, Emily Nodine, Evelyn Gaiser
Distribution Of Diatoms Along Environmental Gradients In The Charlotte Harbor, Florida (Usa), Estuary And Its Watershed: Implications For Bioassessment Of Salinity And Nutrient Concentrations, Emily Nodine, Evelyn Gaiser

The relative abundance of diatom species in different habitats can be used as a tool to infer prior environmental conditions and evaluate management decisions that influence habitat quality. Diatom distribution patterns were examined to characterize relationships between assemblage composition and environmental gradients in a subtropical estuarine watershed. We identified environmental correlates of diatom distribution patterns across the Charlotte Harbor, Florida, watershed; evaluated differences among three major river drainages; and determined how accurately local environmental conditions can be predicted using inference models based on diatom assemblages. Sampling locations ranged from freshwater to marine (0.1–37.2 ppt salinity) and spanned broad nutrient concentration …
Density, Abundance, And Habitat Associations Of The Inland Swamp Sparrow (Melospiza Georgiana Georgiana) In Iowa, Tyler Harms, Stephen Dinsmore
Density, Abundance, And Habitat Associations Of The Inland Swamp Sparrow (Melospiza Georgiana Georgiana) In Iowa, Tyler Harms, Stephen Dinsmore
Tyler Harms
Wetlands continue to decline throughout North America and the Prairie Pothole Region, thus emphasizing the importance of understanding population trends and habitat associations of wetland species to ensure effective conservation and habitat management of those species. We estimated density and abundance and evaluated habitat associations of the Inland Swamp Sparrow (Melospiza georgiana georgiana) in Iowa. We conducted standardized distance sampling surveys for Swamp Sparrows and measured habitat characteristics at 307 wetlands in two regions of Iowa in 2009 and 2010. We used Program Distance to model detection probability and estimate region-specific breeding densities of Swamp Sparrows at Iowa …
Density And Abundance Of Secretive Marsh Birds In Iowa, Tyler Harms, Stephen Dinsmore
Density And Abundance Of Secretive Marsh Birds In Iowa, Tyler Harms, Stephen Dinsmore
Tyler Harms
A decrease in wetland habitats throughout North America has caused a decline in populations of marsh birds. The objective of this study was to estimate population densities and abundances of secretive marsh birds in Iowa. Call-broadcast surveys were conducted in conjunction with distance sampling for eight species of marsh birds at wetlands in three regions of Iowa during 2009 and 2010. Regions were defined by observed microhabitat characteristics which also corresponded to physiographic regions. Region-specific density estimates were obtained using Program Distance for four species of marsh birds for which sufficient detections existed (Pied-billed Grebe [Podilymbus podiceps], Least …

Urbanization—The Bad, The Good, And The Very Good, Rebecca Dolan

Great strides have been made in studying effects of urbanization on plant life in recent years. However, much remains to be learned about how the urban environment acts as a filter on flora. There is some evidence that environments in cities are so similar that they all select for the same plants or plants with the same suite of characteristics, resulting in biotic homogenization, but the jury is still out. We do know that some cities harbor a thriving and diverse native flora. Dolan will talk about what cities can do to increase the chances for long-term survival of native …

Universities are uniquely positioned to lead society toward sustainability and their collaborations with community organizations are essential to this transition. The Biodiesel Program at Loyola University Chicago Center for Urban Environmental Research and Policy provides a case study of course-based service-learning projects facilitating synergies between the university and the community while concomitantly fostering urban sustainability. This article discusses the program’s design andstructure, and describes specific examples of community partnerships that havebenefited the university, the community, and the environment

Hypericum Cumulicola Demography In Unoccupied And Occupied Florida Scrub Patches With Different Time-Since-Fire, Pedro Quintana-Ascencio, Rebecca Dolan, Eric Menges

1 Metapopulation models predict that unoccupied, but suitable, patches will exist for species subject to extinction and colonization dynamics. We compared the demographic responses of Hypericum cumulicola, a rare herbaceous species almost entirely restricted to Florida rosemary scrub, when transplanted to occupied or unoccupied patches. 2 Seedlings were transplanted and seeds buried into Florida rosemary scrub patches differing in time since last fire, and in the presence or absence of H. cumulicola. We used a replicated, factorial design to place the transplants and seeds in the field, and monitored their performance for 18 months. 3 Neither time-since-fire nor prior H. …
