Aspects of Some Compacted Campground Ameliorating Practices
… An attempt was also made to determine the natural recovery time for East Texas sandy loam soils using the campground closure method. Closure or partial (seasonal) closure of campsites reduced compaction to an acceptable level in three years. Roto-tilling alone was the least effective …

Adolescents Who Stutter: Perception of Effective Therapy Techniques
… childhood and data indicates the probability for natural recovery ends near the emergence of adolescence. When stuttering continues into adulthood, it is considered chronic. Currently, there is limited research on which therapy techniques have proven to be most successful with adolescents, a …

FOOD-WEB AND FUNCTIONAL TRAIT COMMUNITY STRUCTURE OF PREDATOR ASSEMBLAGES IN PINE FORESTS UNDER DIFFERENT MANAGEMENT REGIMES
<p>Anthropogenic activities can alter natural disturbance regimes in ecosystems, and thereby affect the structure and function of biological diversity. As many of the world’s ecosystems are degraded beyond natural recovery, well-defined restoration goals are necessary to maintain the ecological …

Northern San Francisco Bay Ecological Risk Assessment: Potential Crude by Rail Incident
… dispersant application coupled with mechanical recovery, natural recovery, and minimal shoreline cleanup with planting. Cost of response actions range from $233,000 to $4.4 million; total cost including natural resource damages is estimated at</strong> <strong>$18.4 million. Recommend increasing …

An investigation of riparian vegetation recovery following invasive alien tree clearing in the Western Cape
… a result of varying levels of disturbance from natural flooding regimes, and this makes them particularly susceptible habitats to invasion by alien plants. In South Africa, particularly the Fynbos Biome, closed-stand invasions by alien Acacia and Eucalyptus species have been able to develop …

Early Successional Processes of Experimentally-Reclaimed Mine Sites in Eastern Ohio and the Restoration of American Chestnut
… established on these sites during the initial natural colonization phase of succession that is occurring there? I found effects of distance from the remnant site forest edge, microtopographic position, the amount of existing vegetation cover at the site, and a small set of soil chemical …

A REVIEW OF THE REMOVAL OF ARUNDO DONAX FROM A RIPARIAN AREA WITHIN SAN TIMOTEO CANYON
… as photographs and data of a site subject to natural recovery. Based on these comparisons it is concluded that the treatment methods used led to a lessened presence of <em>A. donax</em>, and that other invasive species did not grow in its place. Further, as the removal procedures within the …

Apraxia: anaylsis of assessment and rehabilitation
… of single cases, two of which charted the 'natural history' process in recovery of apraxia using task performance and kinematic analysis as outcome measures. Evidence for spontaneous recovery over a six week period was shown in one case. Four single case ABA design investigations were then …

An Ecotoxicological Evaluation of the North Fork Holston River below Saltville, Virginia and Identification of Potential Stressors to Freshwater Mussels (Bivalvia:Unionidae)
… extirpated most mussel populations. Because natural recovery of these populations has not occurred, this research combined field and laboratory assessments to determine the extent of ecological impairment in the river. In situ 60-day Asian clam (Corbicula fluminea) growth studies in 2005 …

Tīmata whakaora, kickstarting recovery - Using bivalves to bioremediate degraded estuarine sediments
… services that they provide. Once degraded, natural recovery can take years due to the loss of long-lived, functionally important benthic species. These species are important in maintaining internal feedback loops, thereby facilitating resilient communities that underpin critical ecosystem …

The ecology of a recovering native predator: the European pine marten (Martes martes)
… to fill the niche as a key predator species. The natural recovery of the pine marten may provide us with insights into possibilities of the recovery of other predator species. The observed recovery of the pine marten in Ireland and Britain so far is of particular interest, as it is recovering …
