The twentieth century confluence of clear-cutting, deer overabundance, and rising nitrogen deposition favored dominance by the shade-intolerant, unpalatable, and nitrogen-demanding black cherry (Prunus serotina) throughout the Allegheny Plateau of th

We assessed Rubus seed bank abundance and variability in 39 stands located throughout northern Pennsylvania as part of a replicated chronosequence of age classes. Seed abundance declined precipitously after stand age 60 in the Allegheny hardwoods or

Beginning in the early 2000s, managers and scientists observed a change in seed production and seed crop frequency for Prunus serotina (Black Cherry), an ecologically and commercially important species in the Alleghany Plateau region. This study focu

Browse of forest understory vegetation by deer and other large ungulates alters ecosystem processes, making it difficult to regenerate forest land in herbivory-stressed areas. Seventy years ago, Aldo Leopold identified problem areas in the United Sta

A soil fertility gradient, ranging from infertile to highly fertile soils, may define whether or not a plant will establish and spread at a site. We evaluated whether or not such a fertility gradient exists for Rosa multiflora Thunb., a nonnative inv

Summary 1. Ungulate browsers, when at high densities, are major drivers of vegetation change in forests world-wide. Their effects operate via a variety of generalizable mechanisms related to plant palatability and relative growth rate with respect to

Question: Seed banks often serve as reservoirs of taxonomic and genetic diversity that buffer plant populations and influence post-disturbance vegetation trajectories; yet evaluating their importance requires understanding how their composition varie

Use of herbicides in forestry to direct successional trajectories has raised concerns over possible direct or indirect effects on non-target organisms. We studied the response of forest birds to an operational application of glyphosate and sulfometur
