Abstract Celastrus orbiculatus is an invasive liana in the Eastern United States. Its native congener, C. scandens, is less common and declining in the Northeast. The correct identification of these two species is often difficult because of their similar vegetative characteristics. Using morphological characteristics of both species growing naturally along a sand dune/forest ecotone, we built models for use in discriminating between the species, given a suite of leaf and fruit traits. We… Expand
Emerging invasion threat of the liana
The woody vine Celastrus orbiculatus (Celastraceae), Oriental bittersweet, is an alien species that recently has been found to be spreading in Europe. Many aspects of its biology and ecology areExpand
Emerging invasion threat of the liana Celastrus orbiculatus (Celastraceae) in Europe
TLDR
Evaluated distribution and habitats, as well as size and age of stands of C. orbiculatus in Lithuania, conclude that climatic conditions in the region are favourable for the growth, reproduction, and invasion of this species. Expand
Genetic characterization of hybridization between native and invasive bittersweet vines (Celastrus spp.)
TLDR
The strong asymmetry in pollen flow that favors fecundity in introduced males has the potential to greatly accelerate the decline of native species by wasting limited female reproductive effort. Expand
Mislabeling of an Invasive Vine (Celastrus orbiculatus) as a Native Congener (C. scandens) in Horticulture
TLDR
The horticultural industry is an important source of invasive ornamental plant species, which is part of the motivation for an increased emphasis on using native alternatives, and the lower price and abundance of mislabeled invasive plants introduces incentives for consumers to unknowingly contribute to the spread of C. orbiculatus. Expand
The biology of invasive alien plants in Canada. 14. Celastrus orbiculatus Thunb.
TLDR
The climatic requirements across eastern Canada, ease of dispersal, and rapid growth suggest that C. orbiculatus will continue to spread across its introduced range, despite being susceptible to glyphosate and triclopyr. Expand
Genetic Characterization of Invasion and Hybridization: A Bittersweet (Celastrus spp.) Story
TLDR
Human commerce, changing biogeochemical cycles, and especially reproductive interference likely played a role in the decline of the native vine and spread of the invasive congener in the past, and their influence will likely increase in the future. Expand
Heterospecific pollination by an invasive congener threatens the native American bittersweet, Celastrus scandens
TLDR
Investigating reproductive interactions between a native North American woody vine and an introduced congener found that the invasive vine had an extreme advantage in both male and female floral production, producing nearly 200 times more flowers per staminate plant and 65 times more Flowers per pistillate plant than the native. Expand
Effects of an Invasive Plant Species, Celastrus orbiculatus, on Soil Composition and Processes
TLDR
Soil characteristics in seven sets of adjacent, paired plots, spanning a range of habitats and soil types, with and without C. orbiculatus were compared to contribute to the growing body of research of the effects of invasive species on ecosystem processes. Expand
Encroachment of Oriental Bittersweet into Pitcher's Thistle Habitat
TLDR
Overall, the density of the invasive liana species was significantly greater in proximity to C. pitcheri than the native species, and the ability of C. orbiculatus to rapidly grow and change the ecological dynamics of invasion sites adds an additional threat to the successional habitats of C., pitcheri. Expand
Oriental bittersweet ( Celastrus orbiculatus ): Spreading by fire
TLDR
Oriental bittersweet is quite responsive to burning as a disturbance and resprouting and root-suckering creates additional opportunities for growth and attainment of the forest canopy, which has important implications for management of invasive lianas in fire-dependent forest landscapes. Expand

Celastrus scandens and celastrus orbiculatus comparisons of reproductive potential between a native and an introduced woody vine
TLDR
Pollen and seed viability tests were conducted with the native Celastrus scandens L.Scandens and the naturalized C. orbiculatus and the possibility that these plants are interspecific hybrids is being investigated. Expand
INTERSPECIFIC HYBRIDIZATIONS BETWEEN THE NATIVE BITTERSWEET, CELASTRUS SCANDENS, AND THE INTRODUCED INVASIVE SPECIES, C. ORBICULATUS
TLDR
Results indicate that the decline of the American bittersweet may be due in part to interspecific hybridizations with the invasive introduced species, and that the distinct genetic identity of C. scandens may be threatened. Expand
Use of architectural and morphometric analysis to predict the flowering pattern of the invasive Rubus on Réunion island (Indian Ocean)
TLDR
This study explored the threshold of this minimal morphological structure and structural maturity level required for plants to reach the reproductive state by describing mesotonic and basitonic axes at two different altitudes and defined the minimum structure required for fruiting in lowland areas. Expand
Differential responses of invasive Celastrus orbiculatus (Celastraceae) and native C. scandens to changes in light quality.
TLDR
Compared how an invasive liana and its closely related native congener responded to changes in the R : FR under controlled, simulated understory conditions provide a mechanistic understanding of the ability of C. orbiculatus to increase height and actively forage for light resources in forest understories, while C. scandens appears unable to foraging for light and instead depends upon a light gap forming.

Developmental patterns of the invasive bramble (Rubus alceifolius Poiret, Rosaceae) in Réunion island: an architectural and morphometric analysis.
TLDR
The aim of this study was to identify the developmental stages of Rubus alceifolius and to determine one or more characteristic morphological markers for each stage, which could benefit land-use managers attempting to control this species before it reaches its optimum developmental stage. Expand

The concurrent decline of the native Celastrus scandens and spread of the non-native Celastrus orbiculatus in the New York City metropolitan area
TLDR
A analysis of the changing distribution of both species in the New York Metropolitan area from the early 1800's through the present suggests that the native C. scandens has declined considerably, while the non-native C. orbiculatus has significantly spread and increased in abundance. Expand

Digital Future for Paleoclimate Estimation from Fossil Leaves? Preliminary Results
TLDR
Digital leaf measurement offers the possibility of continuous, reproducible variables, with the potential to improve paleoclimate estimates as well as the ecological and evolutionary understanding of leaf form, which show promise for testing on an expanded set of floras sufficient to develop statistical models for paleoclimatic studies.

TLDR
It is argued that there are actually two kinds of MR modelling: (1) seeking the best predictive model; and (2) isolating amounts of varianceributable to each predictor variable. Expand
