Disturbance intensity, disturbance extent and ocean climate modulate kelp forest understory communities

Variable effects of climate on forest growth in relation to climate extremes, disturbance, and forest dynamics.

Changes in the frequency, duration, and severity of climate extremes are forecast to occur under global climate change. The impacts of climate extremes on forest productivity and health remain difficult to predict due to potential interactions with disturbance events and forest dynamics-changes in forest stand composition, density, size and age structure over time. Such interactions may lead to...

Assessing log extraction related soil disturbance and solutions to protect soil and reduce disturbance of forest ecosystem.

Skid trails are the main routes for wood extraction and also the main source of runoff and sediment production in Forests. This research was conducted in Kuhmiyan forest of Golestan Province to determine infiltration, compaction, strength (resistance to penetration) and moisture content in three treatment including control (in the forest), wheel ruts and middle of skid trail were measured in th...

Consequences of habitat disturbance and recovery to recruitment and the abundance of kelp forest fishes

Diversity-disturbance relationships: frequency and intensity interact.

An influential ecological theory, the intermediate disturbance hypothesis (IDH), predicts that intermediate levels of disturbance will maximize species diversity. Empirical studies, however, have described a wide variety of diversity-disturbance relationships (DDRs). Using experimental populations of microbes, we show that the form of the DDR depends on an interaction between disturbance freque...

Forest Disturbance Impacts on Residential Property Values

Natural environments and the amenities they offer have fueled much of the population growth in the rural United States (Deller et al. 2001, English et al. 2ooo). In fact, the fastest growing counties in the United States during the early 1990s were non-metropolitan counties that were destinations for retirees or that offered outdoor recreation opportunities (Johnson and Beale 1994). Migration t...
