Celastrus orbiculatus and other invasive lianas may pose a threat to overall forest health by decreasing tree growth, yet we are not aware of any studies that have directly measured such effects.
Celastrus orbiculatus twines around stems and needs small diameter substrates to climb into the canopy (Putz, 1983; DeWalt et al.
Celastrus orbiculatus seedlings establish best in medium to high light environments with mesic rich soils (Leicht-Young et al.
Celastrus orbiculatus is intermediate in its infestation of canopies (Ichihashi and Tateno, 2011); therefore, especially in the early stages of invasion, below ground competition may be the most important effect on tree growth.
Celastrus orbiculatus is a twining liana that is traditionally used in China as an anti-inflammatory agent to treat rheumatism arthritis, fever, edema and bacterial infection (Tong and Moudgil 2007; Wu et al.
The botanical determination of the plant Celastrus orbiculatus has been described in detail previously (Wang et al.
In this study, we for the first time reported the possible molecular mechanisms involved in the strong antioxidative effects of (M)-bicelaphanol A, a novel dimeric podocarpane type trinorditerpene isolated from Celastrus orbiculatus.
The objective of this study was to determine how Celastrus orbiculatus might affect soil chemical and biological properties and processes.
To investigate soil responses to the presence and absence of the invasive species Celastrus orbiculatus, seven paired plots (3 x 3 m) were selected across Mansfield, Connecticut (in the vicinity of 41[degrees]48'30"N, 72[degrees]15'00"W).
Fresh leaves of both Quercus rubra (red oak) and Celastrus orbiculatus were collected in August from one site.
Those spreading slowly include Acorus calamus, Artemisia ludoviciana, Celastrus orbiculatus
, Commelina communis, Hemerocallis fulva (vegetative expansion only), Ligustrum vulgare, Malva neglecta, Medicago sativa, Prunus cerasus, Viola priceana, and Yucca filamentosa.
These species were: Celastrus orbiculatus (Oriental bittersweet), Circaea lutetiana (enchanter's nightshade), Euonymus alatus (burning bush), Lindera benzoin (spicebush), Osmorhiza claytonia (sweet cicely), Parthenocissus quinquefolia (Virginia creeper), Polygonum virginianum (jumpseed), Rosa multiflora (multiflora rose) and Sassafras albidum (sassafras).

Increased leaf litter reduced the emergence of the invasive Celastrus orbiculatus
(Oriental bittersweet) and shifted the allocation of seedling growth to longer hypocotyls and smaller radicles and cotyledons (Ellsworth et al.
Rubus sp, Vitus sp, Celastrus orbiculatus
, Parthenocissus quinquefolia) were no longer marked due to difficulty in isolating the origin of individual stems.
