From:Advances in Environmental BiologyPeer-ReviewedThis investigation was conducted in two separate experiments. In the first experiment, seedlings of wallflower (Cheiranthus cheiri L.) were selected for treatment at 8-cm-height stage. Seedlings were shaked mechanically...

From:Science (Vol. 298, Issue 5596) Peer-ReviewedMethods of risk assessment for alien species, especially for nonagricultural systems, are largely qualitative. Using a generalizable risk assessment approach and statistical models of fish introductions into the Great...

From:Aquatic Mammals (Vol. 44, Issue 2) Peer-ReviewedMarine mammal welfare has most frequently been a topic of discussion in reference to captive animals. However, humans have altered the marine environment in such dramatic and varied ways that the welfare of wild marine...

From:Canadian Journal of Forest Research (Vol. 38, Issue 1) Peer-ReviewedAbstract: Stand structure diversity is hypothesized (i) to increase with stand development and (ii) to be greater in mixedwood stands than in conifer and broadleaf stands. We examined the effects of time since...

From:Fishery Bulletin (Vol. 106, Issue 4) Peer-ReviewedAbstract--Trawling and dredging on Georges Bank (northwest Atlantic Ocean) have altered the cover of colonial epifauna, as surveyed through in situ photography. A total of 454 photographs were analyzed from areas with...
-
From:Canadian Journal of Forest Research (Vol. 38, Issue 4) Peer-ReviewedAbstract: Disturbance effects on plant communities largely reflect the degree of overstory removal, soil disturbance, and attendant vegetation destruction. We examined initial harvest-related impacts of partial and...

From:Bulletin of the Southern California Academy of Sciences (Vol. 111, Issue 2) Peer-ReviewedAbstract.--One of the primary challenges to detecting anthropogenic environmental impacts is the high degree of spatial and temporal variability inherent in natural systems. Planned or routine events that result in...

From:Canadian Journal of Forest Research (Vol. 51, Issue 4) Peer-ReviewedGravel mining is prevalent in forest landscapes across Canada, typically resulting in complete loss of vegetation and topsoil. Despite such extreme disturbance, lodgepole pine (Pinus contorta Dougl. var. latifolia...
-
From:Nature (Vol. 454, Issue 7202) Peer-ReviewedAggregate community-level response to disturbance is a principle concern in ecology because post-disturbance dynamics are integral to the ability of ecosystems to maintain function in an uncertain world. Community-level...
-
From:Journal of Shellfish Research (Vol. 28, Issue 2) Peer-ReviewedABSTRACT The presence of bivalves and bivalve aquaculture can have positive and negative impacts on seagrass and associated benthic communities. Some oyster (Crassostrea gigas) aquaculture methods recently have been...
-
From:Nature (Vol. 557, Issue 7706) Peer-ReviewedAn isolated butterfly population that became dependent on a plant introduced to their habitat by cattle ranchers went extinct after the plant's dominance decreased. An isolated butterfly population that became...
-
From:Mountain Research and Development (Vol. 38, Issue 2) Peer-ReviewedA study of vascular plant species composition, relative abundance, distribution, and anthropogenic threats to these species' survival was carried out in the Galama Mountains in Arsi Mountains National Park, Ethiopia. An...
-
From:The American Midland Naturalist (Vol. 176, Issue 2) Peer-ReviewedAs the trend towards urbanization continues, natural areas near dense human populations can be impacted by development, and increased recreational use of these natural areas may increase disturbance of wildlife. Many...
-
From:Canadian Journal of Forest Research (Vol. 37, Issue 8) Peer-ReviewedAbstract: Rising societal demands for forest resources along with existing natural disturbance regimes suggest that sustainable forest management will increasingly depend on better understanding the cumulative effects...
-
From:Aquatic Mammals (Vol. 43, Issue 2) Peer-ReviewedDisturbance can be defined as any stimulus that, either as a result of natural or human-derived sources, causes a deviation in an animal's typical behavior (Suryan & Harvey, 1999; Jansen et al., 2010). Vessel traffic is...
-
From:Ornis Fennica (Vol. 95, Issue 1) Peer-ReviewedWe surveyed the military training area Adazi to evaluate the effects of disturbance caused by military activities on the abundance of protected bird species considered to benefit from disturbances at the site (SCBD). We...
-
From:Canadian Journal of Forest Research (Vol. 38, Issue 8) Peer-ReviewedAbstract: We used General Land Office survey data (1860-1890) and interpreted aerial photography from the 1930s, 1970s, and 1990s to quantify forest disturbance frequency and spatial patterns for four time periods in...
-
From:Marine Biology (Vol. 166, Issue 1) Peer-ReviewedCoral reef communities are susceptible to anthropogenic disturbance by visitors, such as SCUBA divers. Divers can also have an effect on the behavior of reef fish, which can lead to changes in activities or habituation....
-
From:Bothalia- African Biodiversity & Conservation (Vol. 48, Issue 1) Peer-ReviewedThe impacts of disturbance history on the floristics of Northern Coastal Forest (NCF; South Africa) are unknown. This study compared the floristics of three remnant patches of NCF (in KwaZulu-Natal) with contrasting...
-
From:Canadian Journal of Zoology (Vol. 87, Issue 9) Peer-ReviewedThe Grand Bank ecosystem has undergone significant shifts during the past two decades owing to oceanographic and fishing effects. Effects on upper trophic level seabirds (dietary shifts, reduced reproductive...
