Nitrogen Mineralization and Nitrification in Suburban and Undeveloped Atlantic White Cedar Wetlands
Weixing Zhu,Joan G. Ehrenfeld +1 more
TL;DR: In this article, a 19-week aerobic incubation was conducted to measure N mineralization and nitrification potentials in wetland soils from both developed and undeveloped watersheds, and the results suggest that increases in ash content of peats attributable to sediment transported and deposited in urban runoff, causes increases in pH, which in turn allows large populations of nitrifiers to develop.

Above- and below-ground characteristics of persistent forest openings in the New Jersey Pinelands' 2
TL;DR: Ehrenfeld et al. as mentioned in this paper investigated the above-and below-ground characteristics of persistent forest openings in the New Jersey Pinelands and found that there was a much greater disparity between the openings and the forest matrix in the density of small ericad shrubs than in the number or basal area of the canopy trees, and this disparity was mirrored in the thickness of the litter and organic horizons.

Vegetation of forested wetlands in urban and suburban landscapes in New Jersey1
TL;DR: In this article, a sample of 21 mature deciduous forested wetlands in a densely populated and long-settled region, northeastern New Jersey, in order to describe characteristics of the plant communities of wetlands in such human-dominated landscapes, and test the utility of hydrogeomorphic classification (HGM) in explaining the variation in composition and structure observed among the sites.

The effects of nitrogen addition on the growth of two exotic and two native forest understory plants
TL;DR: The response of exotic and native species to available nutrients does not provide a general mechanism of invasion success, and species response to nitrogen addition is complex, and that exotic species do not all respond similarly to nitrogen inputs.

The influence of urban land use on seed dispersal and wetland invasibility
TL;DR: The results suggest that both the type of adjoining land use and the provision of access to people on trails in urban wetlands can affect the composition of these communities, and may play a role in introducing new species to the interior of the wetland.
