Coastal wetlands food provisioning ecosystem services under a changing climate
Climate change (CC) is projected to affect coastal wetlands in multiple ways, altering their physical structure, community composition, ecological processes, and functions. However, society and ecosystems are deeply interconnected, since humans depend on ecosystems to live, while at the same time …

Guidelines for a Comprehensive Mitigation Management Plan for Texas Coastal Wetlands
In support of the Texas Coastal Management Program, guidelines were developed to assist resource agency decision-makers develop and implement a future comprehensive mitigation management plan for Texas coastal wetlands. Current coastal wetland protection and mitigation strategies that are used in …

The late holocene evolution of coastal wetlands in Argyll, Western Scotland
… on selected sediment cores from four lowland coastal marsh environments in Argyll, Western Scotland. This region of northern Britain has experienced differential crustal uplift and relative sea-level changes throughout the Holocene in response to glacio-isostatic adjustment. The complex …

Plant introductions and community dynamics across environmental gradients in Great Lakes coastal wetlands
Great Lakes coastal wetlands provide vital ecosystem services, including water quality improvement, flood mitigation, and fish and wildlife habitat. However, many of these wetlands have been lost, and those that remain face various threats, including invasion by nonnative plants. Within coastal …

Plant productivity and diversity in coastal wetlands in Mississippi – impact of hydrological extremes
<p>Wetlands are highly productive ecosystems that provide important ecosystem services and are threatened by extreme hydrological events. I evaluated how diversion of freshwater like Bonnet Carré Spillway openings in Louisiana, US, affected vegetation productivity and diversity in salt marshes on …

Herbicide management alters fungal biomass and community composition in Great Lakes coastal wetlands
<p>Wetlands provide many ecosystem services, and invasive species and their management can alter these services. Plant responses to wetland management actions are typically monitored, but less is known about how soils respond. Phragmites australis, an invasive wetland plant, can alter soil …

Characterizing Plankton communities in Lake Ontario coastal wetlands along an urban land-use gradient
… an urban land-use gradient in the Lake Ontario coastal wetlands: Frenchman’s Bay, Lynde Marsh, McLaughlin Bay, and Bowmanville Marsh over two years (2018-2019). One of the study wetlands (McLaughlin Bay) was assessed over three years (2017-2019) for its suitability as a candidate wetland for …

Characterizing water quality, nutrients, and dissolved oxygen dynamics in four Lake Ontario coastal wetlands
Great Lakes coastal wetlands are “keystone” ecosystems, yet their role in regulating nutrient loadings to receiving waters remains unclear. Over a decade of monitoring by the Toronto and Region Conservation Authority revealed that four wetlands (Rouge Marsh, Duffin’s Marsh, Carruthers Marsh, and …

Water Chestnut: Field Observations, Competition, and Seed Germination and Viability in Lake Ontario Coastal Wetlands
… in New York State, particularly Lake Ontario coastal wetlands. It can severely inhibit ecosystem functioning and can be costly to control. To understand this exotic invasive plant more thoroughly, field observations and experiments were performed. The field observations were made in Lake …

Late Quaternary palaeoenvironments of the southern Cape, South Africa palynological evidence from three coastal wetlands
Despite significant advances in palaeoenvironmental research in southern Africa, the late Quaternary palaeoenvironmental history of the region remains incomplete as palaeoclimatic proxy records are temporally and spatially discontinuous. The southern Cape is a key focus area within this region as …

THE IMPACT OF SEA-LEVEL RISE ON COASTAL WETLANDS USING IN-SITU MESOCOSM EXPERIMENTS, LANDSCAPE MODELING, AND TRADITIONAL ECOLOGICAL KNOWLEDGE MAPPING
<p>Sea-level rise is an escalating threat to coastal wetlands as increased inundation and saltwater intrusion can lead to lowered productivity, decreased biomass, and plant death – and ultimately land loss. In chapter one, I detailed the interactive effects of inundation and nitrogen on two …

Biodiversity and Ethnobotanical Uses of Medicinal Plants from the Northern Black Sea Coastal Wetlands /// Биоразнообразие и приложение на лекарствените растения от Северно-Черноморските влажни зони в етноботаниката
… Subject of study are the Northern Black Sea Coastal Wetlands areas: the Durankulak Lake protected area, Shabla-Ezeretz Lake Complex protected area and the Kamchia nature complex. They are an important moulding factor contributing to the existence of a rich and varied flora including a wide …

Effect of Fragmentation and Habitat Type on Coastal Nekton in Mississippi
<p>Coastal wetlands are extremely productive ecosystems that support an abundance of organisms at higher tropic levels. Coastal wetlands also act as important buffers from storms and help protect major cornerstones of coastal economies, such as tourism and fisheries. Despite the clear need for the …

Carbon Sequestration in Tidal Salt Marshes and Mangrove Ecosystems
<p>Wetlands are dynamic systems that provide support to vital environmental functions and services. Wetlands take part in the global carbon cycle by holding organic carbon in biomass, soils and sediments. In recent years, the wetland carbon sequestration capacity has been researched worldwide due …

Spatial and Seasonal Patterns of Above- and Belowground Vegetation Biomass and Potential Drivers in the Pascagoula River Delta, MS
<p>Coastal wetlands provide a valuable wealth of services to the greater coastal ecosystem and human communities. However, threats such as sea level rise and conservation projects, such as freshwater diversions, have the potential to alter coastal wetlands in different ways. In this thesis, I …

Coastal Wetland Dynamics Under Sea-level Rise and Wetland Restoration in the Northern Gulf of Mexico using Bayesian Multilevel Models and a Web Tool
… restoration activities, affects landscapes of coastal wetlands with uncertainties accounted for at the entire northern Gulf of Mexico (NGOM). I developed such a modeling framework – Bayesian multi-level models to study the spatial pattern of wetland loss in the NGOM, driven by relative RSLR, …

The recreation of estuarine ecosystem : a case study at Paull Holme Strays, Humber Estuary, UK.
… partially compensate for the extensive loss of coastal wetlands, which are transitional habitats that form the barriers between seas and oceans and the terrestrial environment. Coastal wetlands historically due to their location have either been altered by flooding or draining to suit human …

Density, Shell Use and Species Composition of Juvenile Fiddler Crabs (Uca Spp.) at Low and High Impact Salt Marshes on Georgia Barrier Islands
Coastal wetlands offer refuge for juveniles of many species, with protection often coming in the form of dense vegetation. Human impacts have led to a 67% loss of coastal wetlands worldwide in the past 300 years, thus decreasing available refuges. There are no studies that show what affect this has …

Functional connectivity of coral reef fishes in a tropical seascape assessed by compound-specific stable isotope analyses
… we quantified the relative contribution of coastal wetlands and reef habitats to Lutjanus ehrenbergii populations on coastal, shelf and oceanic coral reefs in the Red Sea. L. ehrenbergii made significant ontogenetic migrations, traveling more than 30 km from juvenile nurseries to coral reefs …
