8 [1] Salt marshes are often dissected by a network of 9 channels formed by tidal oscillations and related water 10 fluxes. In this note we present a stochastic model able to 11 simulate the formation and evolution of tidal networks in 12 salt marshes. The model is based on a simplification of the 13 shallow water equations that enables the determination of 14 the water surface gradients on the...

Abstract Burrowing animals can profoundly affect the biological structure and ecosystem functions of their environments. For instance, burrowing crabs increase sediment deposition facilitate homogenization turnover, with potential impacts to biogeochemistry. However, relative importance on dynamics vary considerably between, within, habitats. Sediment properties influence how will edaphic condi...

Nutrient supply is widely thought to regulate primary production of many ecosystems including salt marshes. However, experimental manipulation of the dominant marsh grazer (the periwinkle, Littoraria irrorata) and its consumers (e.g., blue crabs, Callinectes sapidus, terrapins, Malaclemys terrapin) demonstrates plant biomass and production are largely controlled by grazers and their predators. ...

Abstract Tidal marshes are dynamic systems whose lateral expansion depends on various biologically, physically, and geomorphologically controlled small- large-scale feedback networks. Due to the bimodal existence of two landscape states at tidal marsh edge (vegetated flat bare flat), high wave energy affecting foremost seaward (pioneer) zone marshes, plant seedlings face challenges: 1) successf...

In 1980 the State of Connecticut began a tidal marsh restoration program targeting systems degraded by tidal restrictions and impoundments. Such marshes become dominated by common reed grass ( Phragmites australis ) and cattail ( Typha angustifolia and T. latifolia ), with little ecological connection to Long Island Sound. The management and scientific hypothesis was that returning tidal action...
