Wetlands represent the largest component of terrestrial biological carbon pool and thus play an important role in global cycles. Most budgets, however, have focused on dry land ecosystems that extend over large areas not accounted for many small, scattered carbon‐storing such as tidal saline wetlands. We compiled data 154 sites mangroves salt marshes from western eastern Atlantic Pacific coasts, well Indian Ocean, Mediterranean Gulf Mexico. The set spans a latitudinal range 22.4°S Ocean to...
Part 1 of this review synthesizes recent research on status and climate vulnerability freshwater saltwater wetlands, their contribution to addressing change (carbon cycle, adaptation, resilience). Peatlands vegetated coastal wetlands are among the most carbon rich sinks planet sequestering approximately as much do global forest ecosystems. Estimates consequences rising temperature current wetland storage future sequestration potential summarized. We also demonstrate need prevent drying...
Canada has natural solutions to support its efforts tackle climate change: forests, wetlands, grasslands, and agriculture.
Much uncertainty exists about the vulnerability of valuable tidal marsh ecosystems to relative sea level rise. Previous assessments resilience rise, which marshes can adjust by sediment accretion and elevation gain, revealed contrasting results, depending on contemporary or Holocene geological data. By analyzing globally distributed data, we found that increases in parity with seemingly confirming previously claimed resilience. However, subsidence substrate shows a nonlinear increase...
Torio, D.D. and Chmura, G.L., 2013. Assessing coastal squeeze of tidal wetlands.As sea level rise accelerates land development intensifies along coastlines, wetlands will become increasingly threatened by squeeze. Barriers that protect inland areas from rising prevent or reduce flows, impermeable surfaces wetland migration to the adjacent uplands. As vegetation succumbs submergence levels on seaward edge a wetland, those prevented decrease in area, if not disappear completely. Tools identify...
Abstract. Tidal wetlands, such as tidal marshes and mangroves, are hotspots for carbon sequestration. The preservation of organic matter (OM) is a critical process by which wetlands exert influence over the global cycle at same time gain elevation to keep pace with sea-level rise (SLR). present study assessed effects temperature relative sea level on decomposition rate stabilization OM in worldwide, utilizing commercially available standardized litter. While per se were minor, we show strong...
The white-footed mouse (Peromyscus leucopus) is an important reservoir host for Borrelia burgdorferi, the pathogen responsible Lyme disease, and its distribution expanding northward. We used Ecological Niche Factor Analysis to identify climatic factors associated with shift of over last 30 years at northern edge range, modeled current potential future (2050) distributions using platform BIOMOD. A mild shorter winter favouring expansion in Québec. With more favorable conditions projected by...
Abstract Mangrove forests have the potential to export carbon adjacent ecosystems but whether mangrove-derived organic (OC) would enhance soil OC storage in seagrass meadows mangroves is unclear. In this study we examine for contribution of mangrove soils on coast North Sulawesi, Indonesia. We found that had significantly higher concentrations, with lower δ 13 C, and bulk density than those at non-mangrove meadows. Soil 30 cm depth ranged from 3.21 6.82 kg C m −2 , was also non-adjacent...
Tidal marshes store large amounts of organic carbon in their soils. Field data quantifying soil (SOC) stocks provide an important resource for researchers, natural managers, and policy-makers working towards the protection, restoration, valuation these ecosystems. We collated a global dataset tidal marsh (MarSOC) from 99 studies that includes location, depth, site name, dry bulk density, SOC, and/or matter (SOM). The MarSOC 17,454 points 2,329 unique locations, 29 countries. generated...

Transformation of agricultural land to natural terrestrial vegetation has been suggested as a means increase soil carbon storage. However, the capacity for storage in soils is limited compared tidal salt marshes, original many coastal lands. In number countries, marshes have “reclaimed,” that drained and diked prevent flooding create suitable conditions dry agriculture. this study we examine spatial temporal patterns accumulation Bay Fundy estimate potential bay's extensive area reclaimed...
The Holocene Mississippi Delta System consists of six cyclic deltaic packages. Associated peat deposits are planar and eutrophic, accumulate in areas abandoned by sedimentation. Peats that formed large-scale interlobe basins the subject this paper. True peats (>75% organic matter) average 81.7% matter on a dry-weight basis. Controls quality lateral distribution are: botanical parent material, balance between subsidence accretion rates, detrital clastic influx marine inundation. Botanical...
