Abstract Wetland soils contain some of the highest stores soil carbon in biosphere. However, there is little understanding quantity and distribution stored our remaining wetlands or potential effects human disturbance on these stocks. Here we use field data from 2011 National Condition Assessment to provide unbiased estimates stocks for at regional national scales. We find that conterminous United States store a total 11.52 PgC, much which within deeper than 30 cm. Freshwater inland...
Abstract The interface found where rivers meet terrestrial systems is an ecotone that has a profound influence on the movement of water and waterborne contaminants. Maintaining or restoring functions characteristics such as natural near stream vegetation channel morphology are important means to safeguard quality in agricultural landscapes. A riparian buffer zone 20 30 m width can remove up 100% incoming nitrate. Denitrification major pathway removal rates depend nitrate loadings, carbon...
Biological indicators of ecosystem integrity are increasingly being sought for use in assessment and goal-setting restoration projects. We tested the effectiveness a plant community-based bioassessment tool, floristic quality index (FQAI) 20 depressional wetlands Ohio, USA. A priori, were classified by type ranked to form disturbance gradient according local landscape condition. Ranks based on surrounding land cover characteristics, vegetated buffer extent human-induced hydrologic alteration...
We discuss aspects of one the most important issues in ecological restoration: how to evaluate restoration success. This first requires clearly stated and justified goals targets; this may seem “obvious” but our experience, step is often elided. Indicators or proxy variables are typical vehicle for monitoring; these must be context targets ultimately compared against those allow an evaluation outcome (e.g. success failure). The monitoring phase critical that a project consider frequency...
We assessed trends in the ecological character of wetlands generally and Ramsar Sites reported 2011, 2014 2017 by Contracting Parties to Convention on Wetlands their national reports. There was more widespread deterioration than improvement generally, with increasingly between 2011 2017. The ecological-character were significantly better those but an Trends worst Africa Latin America Caribbean, recently also Oceania, North Europe. Deterioration Site countries a large average area Sites. This...
Abstract Purpose To assess 1) the cumulative greenhouse gas emissions –GHG- and global warming potential (methane – CH 4 - nitrous oxide) from rice fields in growing fallow seasons, 2) environmental agronomic drivers of emissions, their relative capacity to explain variation. Methods A two-year multisite field experiment covering variability a area NE Iberian Peninsula was conducted with monthly samplings GHG monitoring both factors. Information-theoretic framework analysis used contribution...
Abstract While the direct effects of white-tailed deer ( Odocoileus virginianus ) on vegetation have been intensively studied, less is known about indirect and interactive herbivory lower trophic levels, such as soil microbes their processing carbon pools. We explored how dynamics shift with release from over-browsing by in two mature stands oak hemlock trees. measured pools (for example, organic matter, stocks, litter biomass, stabilization) fluxes respiration, methane uptake, microbial...
ABSTRACT Microbial communities of small freshwater bodies interact dynamically with environmental factors in unknown ways. Longitudinal sampling four ponds Knox County, Ohio, revealed relationships among antibiotic resistance genes (ARGs) and such as pH tannin concentrations. For each site, microbial were collected by filtration, metagenomes analyzed short-read sequencing. ARGs quantified using the ShortBRED pipeline to detect quantify hits a marker set derived from Comprehensive Antibiotic...
