•The sea level rise threshold for marsh drowning is lower than previously thought•No equilibrium after crossing the local drowning•Resilience of microtidal marshes depends weakly on inorganic sediment supply•Predicted widespread loss through runaway fragmentation We use a simplified formulation transport across to explain why are most vulnerable in environments (>60% salt US). find that fractio...

The article presents data on the study of forage yield, nutritional value forage, landscape plant species in pastures Karakalpak part Ustyurt. current state two pasture varieties from Haloxylon ammodendron type was revealed: 1 - ammodendron, Kalidium caspicum gypsum salt marshes with participation Reaumuria fruticosa, R. songarica, Climacoptera transoxana combination Halocnemum strobilaceum dep...

The stable isotope signatures of marine transient and resident nekton were used to investigate trophic linkages between primary producers, marsh macrophytes, phytoplankton, benthic microalgae, and consumers within the Delaware Bay. A whole estuary approach was used to compare the flux of nutrients from primary producers to juvenile weakfish (Cynoscion regalis), bay anchovy (Anchoa mitchilli), a...

In situ persistence of coastal marsh habitat as sea level rises depends on whether macrophytes induce compensatory accretion of the marsh surface. Experimental planters in two North Carolina marshes served to expose two dominant macrophyte species to six different elevations spanning 0.75 m (inundation durations 0.4-99 %). Spartina alterniflora and Juncus roemerianus exhibited similar responses...

Salt marshes are valued for their ecosystem services, and their vulnerability is typically assessed through biotic and abiotic measurements at individual points on the landscape. However, lateral erosion can lead to rapid marsh loss as marshes build vertically. Marsh sediment budgets represent a spatially integrated measure of competing constructive and destructive forces: a sediment surplus ma...

Microorganisms control key biogeochemical pathways, thus changes in microbial diversity, community structure and activity can affect ecosystem response to environmental drivers. Understanding factors that control the proportion of active microbes in the environment and how they vary when perturbed is critical to anticipating ecosystem response to global change. Increasing supplies of anthropoge...

Sea-level rise, as a result of climate change, will likely inflict considerable economic consequences on coastal regions, particularly low-lying island states like Singapore. Although the literature has addressed the vulnerability of developed coastal lands, this is the first economic study to address nonmarket lands, such as beaches, marshes and mangrove estuaries. This travel cost and conting...
