The ecological significance of leaf movements in Rhododendron maximum
… the ecological significance of leaf movements in Rhododendron maximum, which is a subcanopy, evergreen species distributed in seasonally cold environments. Leaf movements could be necessary for maintaining a favorable energy balance and/or avoiding photoinhibition and photooxidation. A series of …

Effectiveness of Treatments to Reduce Rhododendron maximum and Promote Tree Seedling Regeneration in the Southern Appalachians
Rosebay rhododendron (Rhododendron maximum L.) is an evergreen ericaceous shrub that plays a dynamic role in the southern Appalachian forests. Commonly located on mesic sites, this understory shrub forms dense thickets that greatly reduce the amount of light available to herbaceous and woody plants …

The Inhibitory Effect of Rhododendron maximum L. (Ericaceae) Thickets on Mycorrhizal Colonization of Canopy Tree Seedlings
Thickets of Rhododendron maximum (Rm) in the southern Appalachians impose severe limitations on the regeneration of hardwood and coniferous seedlings. Interactions between Rm thickets and ectomycorrhizal colonization were examined to explain seedling inhibition. Experimental blocks were established …

The photoprotective role of thermonastic leaf movements in Rhododendron maximum: potential implications to early spring carbon gain
Rhododendron maximum L. is a dominant subcanopy species in the southern Appalachian Mountains. R. maximum undergo distinct thermonastic leaf movements (TLM). The purpose of these movements has not yet been determined. Previous studies have suggested TLM are a photoprotective mechanism for the …

Inhibition of Canopy Tree Seedlings by Thickets of <I>Rhododendron maximum</I> L. (Ericaceae) in an Eastern Deciduous Forest
<I>Rhododendron maximum</I> L. (Ericaceae) is an evergreen shrub that grows in dense thickets and currently covers large areas of the understory in the deciduous forests of the southeastern United States. Thickets of R. maximum are inhibitory to recruitment and regeneration of many understory …

The response of four ericaceous shrub species to multiple environmental resource variation
… and water in an experimental garden study. <i>Rhododendron maximum</i> and <i>Kalmia latifolia</i> were able to acclimate photosynthetically to high and low irradiance under both high and low water availability. <i>Rhododendron catawbiense</i> and <i>R. minus</i> showed significantly higher …

Effects of prescribed burning, mechanical and chemical treatments to curtail rhododendron dominance and reduce wildfire fuel loads
Rosebay rhododendron (Rhododendron maximum L.) is an ericaceous shrub commonly found in riparian areas of the Appalachian Mountains. After more than a century of fire exclusion in the U.S., the distribution of R. maximum and its dominance of forest understories have increased. Rhododendron …

Survey of the Native and Nonnative Vascular Plant Species of Three Islands in Lake Winnipesaukee, New Hampshire
… on plants of interest including certain rare (Rhododendron maximum), introduced (Halesia carolina) and potentially invasive species (Poa compressa). Data from the study shows that the species richness on all the islands increased significantly from 1978 to 1991 on all three islands but remained …

The Short Term Responses of Benthic Macroinvertebrates to the Removal of Riparian Rhododendron in Southern Appalachian Streams
… This paper addresses the management impacts of Rhododendron maximum removal in the riparian and upslope areas previously occupied by hemlock. This study measured the consequences macroinvertebrates faced due to riparian Rhododendron removal from 300 m reaches of two low order streams. Two …

Leveraging the Landsat Archive to Track Understory Evergreen Shrub Expansions in the Coweeta Basin, North Carolina
… has driven two common evergreen shrubs, rosebay rhododendron (Rhododendron maximum) and mountain laurel (Kalmia latifolia), to expand and proliferate in areas where they were once restricted. These two common shrubs are recognized agents of change in Appalachian forests because of their abilities …

The Influence of Dense Understory Shrubs on the Ecology of Canopy Tree Recruitment in Southern Appalachian Forests
… beneath rapidly spreading thickets of Rhododendron maximum L. (Ericaceae) in southern Appalachian forests is an issue of major concern because of the potential impacts on forest productivity, hydrology and wildlife habitat. Many studies have investigated the causes of seedling …

Distribution and Dynamics of the Evergreen Understory Layer in Central Appalachian Highland Forests
… understory layer communities dominated by Rhododendron maximum L. and/or Kalmia latifolia L. may exert significant controls on regeneration of overstory trees, carbon sequestration, and nutrient retention in central Appalachian forests, but their distribution and ecological importance are …

Diversity and Ecology of Mycorrhizal Fungi Associated With Oak Seedlings in the Appalachian Mountains
… ericoid shrub dominance (Kalmia latifolia and Rhododendron maximum) and EM fungi was observed. We present a listing of EM fungus types with associated ranges of edaphic parameters and ericoid shrub abundance. The family Sebacinaceae is a basal hymenomycete lineage that includes members of the …

The available nutrients in selected deer browse species growing on different soils
… In addition to the above three species, rhododendron (Rhododendron maximum) and buffalo nut (Pyrularia pubera) were collected from the Brallier study area and analyzed. One-third of the samples of dogwood, locust, and maple that were collected after leaf fall in October 1955, were …
