Carbon allocation and nitrogen acquisition in a developing Populus deltoides plantation.
Fertilizer-induced changes in allocation were explained by accelerated development and specific N-uptake rates increased during the growing season and were higher for fertilized trees than for control trees. Expand
Fine root dynamics in a developing Populus deltoides plantation.
Cumulative fine root production and mortality showed strong seasonal patterns; production was greatest in the middle of the growing season and mortality was greatest after thegrowing season; small diameter roots at shallow soil depths cycled more rapidly than larger or deeper roots. Expand
Ground-layer plant community responses to even-age and uneven-age silvicultural treatments in Wisconsin northern hardwood forests
The results suggest that ground-layer plant communities in northern hardwood ecosystems are either resistant to change or have recovered within the 40 years since disturbance in the even-age treatments and within 10 years since disturbances in the uneven- age treatments. Expand
Do deer and shrubs override canopy gap size effects on growth and survival of yellow birch, northern red oak, eastern white pine, and eastern hemlock seedlings?
This study highlights the management challenges of using gap size as a tool to influence future forest composition in forests with overly abundant deer and pervasive shrub layers and underscores the importance of silvicultural prescriptions that include measures for reducing these impacts. Expand
Challenges facing gap-based silviculture and possible solutions for mesic northern forests in North America
Gap-based silvicultural systems were developed under the assumption that richness, and diversity of tree species and other biota positively respond to variation in size of harvest-created canopyExpand
Asynchrony among local communities stabilises ecosystem function of metacommunities
Spatial heterogeneity should be a major focus for maintaining the stability of ecosystem services at larger spatial scales because asynchronous responses among local communities were linked with species’ populations fluctuating asynchronously across space. Expand
Diversifying the composition and structure of managed late-successional forests with harvest gaps: What is the optimal gap size?
Managing forests for resilience is crucial in the face of uncertain future environmental conditions. Because harvest gap size alters the species diversity and vertical and horizontal structuralExpand
Harvest-created canopy gaps increase species and functional trait diversity of the forest ground-layer community
The results suggest that size of harvest-created gaps and proportion of forest in gaps can be manipulated to attain biodiversity goals but evaluating the regional species pool and seed sources will be important to maintain or restore conservation value. Expand
Legacy effects of prescribed fire season and frequency on soil properties in a Pinus resinosa forest in northern Minnesota
Abstract Prescribed fire is a widely used ecosystem management approach and the vast majority of burns are conducted during the dormant season; however, these burning conditions (and therefore theExpand
Long-Term Research at the USDA Forest Service's Experimental Forests and Ranges
The network of experimental forests and ranges administered by the US Department of Agriculture Forest Service consists of 77 properties that are representative of most forest cover types and many ecological regions in the nation and can contribute greatly to formation of new networks of environmental observatories.
