In the southern Appalachian mountains a subcanopy species, Rhododendron maximum, inhibits the establishment and survival of canopy tree seedlings. One of the mechanisms by which seedlings could be inhibited is an allelopathic effect of decomposing litter or leachate from the canopy of R. maximum (R.m.) on seed germination, root elongation, or mycorrhizal colonization. The potential for allelopathy by R.m. was tested with two bioassay species (lettuce and cress), with seeds from four native tree… Expand
Does Rhododendron maximum L. (Ericaceae) Reduce the Availability of Resources Above and Belowground for Canopy Tree Seedlings?
TLDR
The data indicate that competition for resources both above- and belowground is an important mechanism for inhibition of canopy tree recruitment by R. maximum, and water availability and the ability to accumulate soil nutrients are equally or more important than light to survival of canopy Tree seedlings in the presence of a subcanopy thicket.

Effects of Rhododendron maximum Thickets on Tree Seed Dispersal, Seedling Morphology, and Survivorship
TLDR
There was no significant effect of R. maximum on seed reaching the forest floor for Acer rubrum, Liriodendron tulipifera, Quercus rubra, quercus prinus, Carya spp. Expand
Investigating the Allelopathic Potential of Kalmia latifolia L. (Ericaceae)
TLDR
It is suggested that allelopathy is not a strong mechanism in the inhibition of canopy tree recruitment by K. latifolia, an important component of southern Appalachian forest understories. Expand
Allelopathic potential in the laurel forest of Tenerife, Canary Islands
TLDR
Two factors, allelopathy and slug predation, could together have great influence in shaping structure and composition of this forest type. Expand
Characterizing Betula Litwinowii Seedling Microsites at the Alpine-Treeline Ecotone, Central Greater Caucasus Mountains, Georgia
TLDR
Microsite characteristics of successfully established Betula litwinowii seedlings at the alpine-treeline ecotone are described, suggesting that a higher photosynthetic capacity and a deciduous life history may provide both tolerance and avoidance to the physiological stresses associated with high sky exposure for B. litwinowingii. Expand
Improved control of Rhododendron ponticum for environmental management
TLDR
A new understanding is brought to the invasion dynamics of R. ponticum that can be used in identifying habitats vulnerable to invasion and in developing a post clearance management strategy for preventing reinvasion of sites. Expand
The influence of the monocarpic herb, Isoglossa woodii, on subtropical forest tree dynamics and diversity.
Dominant understorey species, such as herbs, ferns, palms and shrubs may influence forest tree species diversity and dynamics. Their influence may be through shading the forest floor, therebyExpand
Leaf litter of Kageneckia angustifolia D. Don (Rosaceae) inhibits seed germination in sclerophyllous montane woodlands of central Chile
TLDR
Under laboratory conditions, K. angustifolia leaf litter leachates inhibited seed germination of its own seeds and of the two native shrub species, and chemical effects are likely involved in the negative effects of leaf litter on the recruitment of this species in the montane sclerophyllous woodland of central Chile. Expand
Rhododendron thickets alter N cycling and soil extracellular enzyme activities in southern Appalachian hardwood forests
TLDR
The alteration of the N cycle via the formation of polyphenol–organic N complexes may contribute to hardwood seedling suppression, while the enzymatic release of these complexes by ericoid mycorrhizal fungi may increase N acquisition for R. maximum and contribute to its expansion in southern Appalachian forests. Expand
The mechanisms used by the invasive shrub Rhododendron ponticum to inhibit the growth of surrounding vegetation
TLDR
It is demonstrated that light availability, temperature, water availability, organic matter and soil pH were all different beneath stands of R. ponticum, and that the inhibition of growth of the native species is due to a complex combination of biotic and abiotic factors. Expand

Suppression of ectomycorrhizae on canopy tree seedlings in Rhododendron maximum L. (Ericaceae) thickets in the southern Appalachians
TLDR
Thickets of Rhododendronmaximum (Ericaceae) (Rm) in the southern Appalachians severely limit regeneration of hardwood and coniferous seedlings, and mycorrhizal parameters were correlated with some growth parameters only for hemlock Seedlings, but did not explain most of the variation observed. Expand
The effect of understory palms and cyclanths on the growth and survival of Inga seedlings
TLDR
It is suggested that understory vegetation, especially broad-leaved palms and palm-like cyclanths, acts as a filter affecting the distribution and abundance of establishing seedlings. Expand
The effect of Kalmia angustifolia on the growth, nutrition, and ectomycorrhizal symbiont community of black spruce
TLDR
Field observations suggest that on many sites where K. angustifolia grows, black spruce seedlings become chlorotic and stunted, and hypotheses suggesting possible roles for nutrient competition, allelopathy, and K. dimorphospora are proposed are proposed. Expand

Effects of Rhododendron maximum L. on Acer rubrum L. Seedling Establishment
TLDR
Results suggest that in addition to the light limitation associated with R. maximum, edaphic effects such as low soil moisture or allelopathic compounds may inhibit Acer rubrum success. Expand
Pattern and Performance of Understory Bamboos (Chusquea spp.) under Different Canopy Closures in Old‐Growth Oak Forests in Costa Rica1
TLDR
The effect of canopy closure on spatial and morphological patterns of three understory Chusquea species was studied in pristine upper montane oak forests, finding that C. tomentosa and C foliosa have a higher degree of morphological plasticity than C talamancensis, which appears to be more shade tolerant.

TLDR
The results suggest that the nutritional stress and poor growth of conifers on salal-dominated CH clearcut sites in coastal British Columbia can be explained by inherently low forest floor nutrient availability. Expand

TLDR
Transition matrices, based on size-based life table data, have been developed as an effective method to quantify life history aspects and are predicted to decrease by 14% in 50 yr, but that the DBH distribution of trees > 10 cm diameter will change little. Expand
