Frugivory and North American Migrants in a Neotropical Second-Growth Woodland
Bird species visitation to a single fruit source fluctuates over time due to changes in fruit density, presence of behaviorally dominant birds, and availability of alternative fruit sources. As a result, different bird species are major consumers of a fruit source at various periods of the fruiting …

Regeneration Dynamics in Old -Growth and Second-Growth Southern Appalachian Cove Forests
Regeneration dynamics in an old-growth and a second-growth cove forest in the Great Smoky Mountains of eastern Tennessee were studied over the course of four contiguous growing seasons. Woody shrub and herbaceous species in the regeneration layer were also investigated. The effects of disturbance …

The Development Of Old-Growth Structural Characteristics In Second-Growth Forests Of The Cumberland Plateau, Kentucky, U.s.a.
… meeting one or more of the definitions of old-growth forest in use today. However, many recovering, mature forests currently exist that might be redeveloping old-growth structure and function. To assess the development of old-growth forest characteristics in second-growth forests, 70 - 90 year …

Bat Species Diversity in Old-Growth vs. Second Growth Forests in Lilley Cornett Woods, Letcher County, Kentucky
<p>Bat activity in old-growth forests (+150 years) is a subject that is poorly understood. The majority of old-growth forests are located in the northwestern portion of the United States, and with current silviculture practices, many forests are being cut. There have been no published studies that …

Effects of Forest Fragmentation on Central Amazonian Bird Demography
… Despite the potential value of Amazonian second growth, we lack comparisons of demography among second growth, continuous forest, forest fragments in regenerating landscapes, and truly isolated fragments. Here, we used point-count and capture data to compare Amazonian bird communities …

The status and distribution of terrestrial amphibians in old-growth forests and managed stands
… the abundance of terrestrial amphibians in old-growth forests and young and mature post-harvest stands. I also examine the habitat features with which they are strongly associated, and contrast these between old growth and second growth to gain insight on the specific effects of logging …

Changes in stand structure and species diversity following clearcutting in central Appalachian hardwoods
The clearcutting of second-growth Appalachian hardwood forests may cause a reduction in species diversity of the new cohort. This study measured changes in species composition, diversity, and stand structural characteristics following clearcutting of a second-growth hardwood forest. To evaluate the …

Laminated root rot: ecology relationship and stand productivity impacts in coastal Douglas-fir ecosystems of British Columbia
… of laminated (Phellinus) root rot in coastal second growth Douglas-fir ecosystems of southeastern Vancouver Island was investigated in 139 ecosystems centered around 215 growth and yield permanent sample plots (PSP's). The impact of Phellinus root rot on stand productivity was estimated from …

Deadwood Dynamics: A Case Study at Prince William Forest Park, Virginia
… to rapidly estimate deadwood of long unmanaged second growth forests to help inform future management decisions. Management agencies within this region, such as the National Park Service, may benefit from a greater understanding of the potential factors that influence deadwood accumulation, …

Carbon Storage in Old-Growth Western Larch (Larix occidentalis) Forests of Western Montana
… years, the structural development of western old-growth ecosystems has been of great interest in ecological research. As the loss of historical forested acreage in western Montana became more widely recognized, the preservation of frequent-fire old-growth stands became a focus of forest …

Growth and characterization of FeSi nanowires by chemical vapor deposition for gas sensing applications
… The nanowires followed the vapor solid (VS) growth mechanism, which does not require the use of a metal catalyst; the native silicon oxide layer on the silicon substrates played the role of the catalyst in the growth of these nanostructures. A second growth mechanism, involving the use of a …

Implicit Environmental Value of Old Growth on the United States National Forests in Western Washington
… for the value of total non-timber services in second growth forests, and public managers have considered the significant role of old growth to its environment and ecosystem. The result of structural change test, however, illustrates that the introduction of the National Forest Management Act of …

Anthropogenic impacts on Cerrado conservation and biodiversity and carbon restoration of Atlantic Forest
… act in the assembly of communities in forests of secondary growth of the Atlantic forest. For this, 12 fragments of Cerrado stricto sensu with different levels of disturbances and inserted in different landscapes and 42 areas in natural regeneration after the last eucalyptus cut in an Atlantic …

The response of Keen's mice populations to riparian restoration treatments on Lyell Island, Haida Gwaii
… the forest canopy for promoting understory plant growth and diversity. The purpose of my study was to test the importance of coarse woody debris (CWD) and canopy light transmission to habitat quality for Keen's mouse (Peromyscus keeni keeni) in young riparian forest stands (60-70 years) one year …

Coarse Woody Debris in Industrially Managed Pinus taeda Plantations of the Southeastern United States
… Most CWD research has been conducted in old-growth and unmanaged, second-growth forests. However, less is understood about CWD in intensively managed ecosystems, such as industrialized southern pine plantations. The objectives of this study were to determine the climatic and ecological …

Thirty-year Changes in Mineral Soil C in a Cumberland Plateau Forest as Influenced by Inorganic-N, Soil Texture, and Topography
… points on the Camp Branch Watershed, a second growth oak forest on the Cumberland Plateau in central Tennessee, in July of 1976 and archived. These points were re-sampled in July of 2006 and both archived and new samples of the 0 to 10 cm increment of the mineral soil were analyzed for C …

Local and landscape scale effects of fragmentation on aerial insectivorous bats in the Amazon
… diversity exhibited degradation in the secondary forest matrix around the smallest fragments compared to continuous forest. This negative effect became less pronounced as fragment size increased and in contrast, forest edges generally contained higher diversity. We only found subtle …

A Denroecological Analysis of Disturbance of Remnant Pinus Palustris, Southeastern Virginia
… of stand dynamics on Pinus palustris in second-growth loblolly pine stands. These results are probably due to the mix of species within these stands and competition from loblolly pine as both the dominant understory and overstory species. Using Black and Abrams (2003) boundary line …
