Hydroperiod Influences on Nutrient Dynamics in Decomposing Litter of a Floodplain Forest
Lack of clarity regarding the relationship between hydroperiod and decomposition dynamics has long been a barrier to the development of a clear understanding of floodplain biogeochemistry.Expand
EFFECTS OF MICROTOPOGRAPHY AND DISTURBANCE ON FINE-ROOT DYNAMICS IN WETLAND FORESTS OF LOW-ORDER STREAM FLOODPLAINS
TLDR
It is suggested that fine-root dynamics in forested wetlands are affected by microtopography and possibly by disturbance to the overstory, andfine-root NPP was greatest in hollows followed by flats and hummocks. Expand
Tree shelters and weed control: Effects on protection, survival and growth of cherrybark oak seedlings planted on a cutover site
TLDR
The use of tree shelters with weed control was the most effective treatment for promoting 2-year ground-line diameter, height, and stem volumegrowth and preventing browsing. Expand
Cutleaf coneflower (Rudbeckia laciniata L.) response to ozone and ethylenediurea (EDU).
TLDR
The results demonstrated that O(3) altered the physiology and productivity of cutleaf coneflower, and although reducing visible injury EDU may be phytotoxic at higher concentrations. Expand
Ozone impacts on loblolly pine (Pinus taeda L.) grown in a competitive environment.
TLDR
Findings regarding the trees growing in the CF treatments, are contrary to previous reports regarding ozone impacts to loblolly pine grown without competition from other vegetation. Expand
Genotype–nutrition interactions in field-planted loblolly pine
TLDR
Four families of loblolly pine were compared to determine inherent differences in productivity and nutrient efficiency for two nutrient regimes, and family variation in element ratios, internal translocation, and the graphical techniq... Expand
Diversity of an early successional plant community as influenced by ozone
An early successional plant community was exposed to various ozone concentrations for two growing seasons (1994–1995) in open-top chambers in Auburn, Alabama, USA. The ozone treatments were: AA,Expand
Mature Black Cherry Used as a Bioindicator of Ozone Injury
Incidence and severity of foliar symptoms due to ambient ozone exposures were documented on mature black cherry (Prunus serotina) in two National Parks [Great Smoky Mountains National Park (GRSM) andExpand
Visible Ozone Injury on Forest Trees in Great Smoky Mountains National Park, USA
During the summer of 1991 ozone injury trend plots in Great Smoky Mountains National Park, USA, consisting of mature black cherry, sassafras and yellow-poplar were established near three ozoneExpand
Visible foliar injury caused by ozone alters the relationship between SPAD meter readings and chlorophyll concentrations in cutleaf coneflower
TLDR
Several factors are involved in altering the calibration of the SPAD meter for measuring chlorophyll amounts in visibly ozone-injured leaves, with the most likely being changes in either light absorption or scattering resulting from tissue necrosis. Expand
