Forest Dynamics In Mesic Northern Hardwoods Following Windthrow And Salvage Logging , Katharyn Dianne Derr Jan 2006

Forest Dynamics In Mesic Northern Hardwoods Following Windthrow And Salvage Logging , Katharyn Dianne Derr

Retrospective Theses and Dissertations

Post-disturbance, or salvage, logging is a highly debated topic within natural resource science and management as its effects on forest recovery are not well understood. We examine a 25-year forest response to a 1977 severe wind disturbance on the Flambeau River State Forest in Wisconsin, USA, some of which was salvage logged. Our results show salvage logging affects the rate of vegetation recovery, microtopography, and soil composition within this mixed broad-leaved deciduous and conifer forest. Although salvaged and unsalvaged areas are similar in tree species composition, tree biomass is higher and forest microtopography is more pronounced within the unsalvaged area ...


Riparian Land-Use Impacts On Stream Bank Soil And Phosphorus Losses From Grazed Pastures , Mustafa Tufekcioglu Jan 2006

Riparian Land-Use Impacts On Stream Bank Soil And Phosphorus Losses From Grazed Pastures , Mustafa Tufekcioglu

Retrospective Theses and Dissertations

An emerging challenge in watershed-scale research is to quantify the extent of sediment contributed to receiving waters from stream banks versus overland flow from critical source areas, and to develop management strategies to reduce stream bank erosion. The objective of this research was to compare the amounts of sediment and phosphorus loss from critical stream bank source areas to receiving waters via overland flow and stream bank erosion from riparian grazed pasture under different stocking densities (cow-calf pair ha -1). Rainfall simulations were used to calculate sediment and P loads from overland flow from stream-side livestock loafing and access points ...

Anatomy And Physiology Of Sugar Maple (Acer Saccharum March) Seedlings Uninoculated Or Inoculated With The Vesicular-Arbuscular Endomycorrhizal Fungus Glomus Etunicatum , William Jesse Yawney Jan 1985

Anatomy And Physiology Of Sugar Maple (Acer Saccharum March) Seedlings Uninoculated Or Inoculated With The Vesicular-Arbuscular Endomycorrhizal Fungus Glomus Etunicatum , William Jesse Yawney

Retrospective Theses and Dissertations

Mycorrhizal inoculation improved the phosphorus (P) nutrition of sugar maple seedlings in the law P study soil. This improved P nutrition was not translated into growth, however. This was interpreted as evidence for the fungal carbohydrate drain or, perhaps, a threshold level of P needed for shoot growth was not reached in the low P soil even with the improved nutrition attributed to the fungus. In addition, inoculation reduced plant carbohydrate levels in the fall and affected the levels of various nutrients in plant parts. It was proposed that a more efficient endophyte, in terms of its effect on P ...
