Seedling growth rate and root traits in the maize Nested Association Mapping (NAM) panel Open
This paper characterizes variation in shoot and root traits collected from the founders of the Maize Nested Association Mapping panel, which was designed to maximize genetic diversity while ensuring appropriate flowering in eastern North A…

Practical Guide to Measuring Wetland Carbon Pools and Fluxes Open
Wetlands cover a small portion of the world, but have disproportionate influence on global carbon (C) sequestration, carbon dioxide and methane emissions, and aquatic C fluxes. However, the underlying biogeochemical processes that affect w…

Vegetation Affects Timing and Location of Wetland Methane Emissions Open
Common assumptions about how vegetation affects wetland methane (CH 4 ) flux include acting as conduits for CH 4 release, providing carbon substrates for growth and activity of methanogenic organisms, and supplying oxygen to support CH 4 o…

Nitrogen enrichment stimulates wetland plant responses whereas salt amendments alter sediment microbial communities and biogeochemical responses Open
Freshwater wetlands of the temperate north are exposed to a range of pollutants that may alter their function, including nitrogen (N)-rich agricultural and urban runoff, seawater intrusion, and road salt contamination, though it is largely…

Vegetation affects timing and location of wetland methane emissions Open
Common assumptions about how vegetation affects wetland methane (CH) flux include acting as conduits for CH release, providing carbon substrates for growth and activity of methanogenic organisms, and supplying oxygen to support CH oxidatio…

Plant and Soil Carbon Responses to Invasive Typha Management in Great Lakes Coastal Wetlands Open
We quantified how control of a ubiquitous Great Lakes region invasive (Typha × glauca) shifts plant-mediated C cycling and belowground properties and processes. Two field experiments implemented large scale treatment plots (~1-ha to 3-ha) …

Greenhouse Gas Flux Response to Harvest of Typha x Glauca in a Great Lakes Coastal Wetland Open
Although harvesting invasive species can promote biodiversity during wetlands restoration, there is little known about this mechanical treatment’s impacts on greenhouse gas flux, a significant biosphere-atmosphere interaction. We quantifie…
