Many lakes have experienced a transition from a clear into a turbid state without macrophyte growth due to eutrophication. There are several measures by which nitrogen (N) and phosphorus (P) concentrations in the surface water can be reduced. We used the shallow lake model PCLake to evaluate the effects of three measures (reducing external nutrient loading, increasing relative marsh area, and i...

Traditional methods of managing salt marsh mosquitoes focus primarily on maximizing the reduction of mosquito populations, with minimizing environmental impact as a secondary consideration. An environment-oriented approach to salt marsh management for mosquito control, runnelling, is described and compared with other forms of habitat modification such as ditching and Open Marsh Water Management...

Abstract. The persistence of tidal wetland ecosystems like salt marshes is threatened by human interventions and climate change. In particular, the threat accelerated sea level rise (SLR) has increasingly gained attention scientific community recently. However, studies investigating effect SLR on plants vertical marsh accretion are usually restricted to species or do not consider phenotypic pla...

In an earlier t reatment [Destro & Marsh (1987). Acta Cryst. A43, 711-718], an at tempt was made to predict the shapes of high-angle 0-20 scan profiles by convoluting a low-angle profile with the presumedly known spectral distr ibution function for the incident (crys ta l -monochromat ized Mo K a ) radiation but it was found necessary to introduce a third component, an 'aberrat ion funct ion ' ...

A large body of literature exists across different contexts on unequal societal role burdens experienced by the different sexes (Cornwall, Harrison & Whitehead, 2007; Faust, 2013; Jacobs, 1996; Kabeer, 2005; Powell, 2005; Rao, 2006; Rao & Kelleher, 2003; Smyth, 2007; Unterhalter & North, 2011; Wendoh & Wallace, 2005), as well as in the South African context (Geisler, 2000; Hassim, 2006; McEwan,...

Accurate characterization of marsh elevation and landcover evolution is important for coastal management and conservation. This research proposes a novel unsupervised clustering method specifically developed for segmenting dense terrestrial laser scanning (TLS) data in coastal marsh environments. The framework implements unsupervised clustering with the well-known K-means algorithm by applying ...

Complexity theory predicts that local feedback processes may strongly affect the organization of ecosystems on larger spatial scales. Whether complexity leads to increased resilience and stability or to increased vulnerability and criticality remains one of the dominant questions in ecology. We present a combined theoretical and empirical study of complex dynamics in mineralogenic salt marsh ec...

Coupling experiments at small spatial scales with large-scale surveys can help to generalize experimental results across large spatial scales. The goal of the present study was to evaluate patterns of crab herbivory within and, at a larger scale, between many southwestern (SW) Atlantic salt marshes. Hence, we conducted experiments in an Argentinean salt marsh to elucidate the effects of crab Ch...

Salt marshes are among the most productive ecosystems on Earth, and play an important role in the global carbon cycle. Net carbon dioxide (CO2) ecosystem exchanges in coastal salt marshes remain poorly investigated. In Spartina alterniflora dominated North American Atlantic coast marshes, the lack of a clear understanding of how Spartina alterniflora responds to flooding limits our current abil...

A fundamental question in ecology is how biological interactions and biogeographic processes interact to determine the biodiversity of local sites. We quantified patterns of plant species diversity on transects across elevation at 59 salt marsh sites in Georgia and 49 sites in Texas. Although these regions have similar climates and floras, we anticipated that diversity might differ because of d...
