When plants are subjected to leaf canopy shade in forest understories or from neighboring plants, they not only experience reduced light quantity, but light quality in lowered red : far red light (R : FR). Growth and other developmental responses of plants in reduced R : FR can vary and are not consistent across species. We compared how an invasive liana, Celastrus orbiculatus, and its closely related native congener, C. scandens, responded to changes in the R : FR under controlled, simulated… 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
The non-native plant Rosa multiflora expresses shade avoidance traits under low light availability.
TLDR
In deciduous forest understories, R. multiflora appears to make use of a lengthened growing season in spring and fall, and therefore, substantial growth and spread through intact forests appears dependent on canopy gaps. Expand
Morphology and Hydraulic Architecture of Vitis vinifera L. cv. Syrah and Torrontés Riojano Plants Are Unaffected by Variations in Red to Far-Red Ratio
TLDR
None of the Vitis vinifera varieties assessed displayed the classical morphological and hydraulic responses associated to SAS induced by phytochromes, and low lateral R:FR did not affect dry matter partitioning, water- related traits, or water-related physiology. Expand
Lianas escape self-thinning: Experimental evidence of positive density dependence in temperate lianas Celastrus orbiculatus and C. scandens
TLDR
This study demonstrates that these lianas can escape the consequences of high density and thus the self-thinning law that affects self-supporting plants, and suggests a broader hypothesis about lianaas in general: their greater flexibility in allocating growth resources allows them to grow taller and thinner without collapsing and thereby potentially escape shading and mortality even at high densities. Expand
Comparative performance of invasive and native Celastrus species across environmental gradients
TLDR
This study shows the utility of manipulative experiments, particularly those using congeneric native species as benchmarks, for assessing the causes and predicting the course of invasions. Expand
Mycorrhizae and soil phosphorus affect growth of Celastrus orbiculatus
TLDR
It is suggested that in the presence of mycorrhizae or sufficient phosphorus, C. orbiculatus can respond by preferentially allocating energy to above-ground growth, thus supporting its liana growth form onto trees and allowing the exotic to outcompete native species for light resources. Expand
Are temperate mature forests buffered from invasive lianas?1
TLDR
Celastrus orbiculatus poses a substantial threat to mature forests as it will persist in the understory until a canopy gap or other disturbance provides the light and supports necessary for it to ascend to the canopy and damage tree species. Expand
Functional shifts in leaves of woody invaders of deciduous forests between their home and away ranges.
TLDR
It is concluded that, for this group of species, newly evolved phenotypes in the invaded range are more important than preadaptation for their success as shade-tolerant forest invaders. Expand
Distinguishing Native (Celastrus Scandens L.) and Invasive (C. Orbiculatus Thunb.) Bittersweet Species Using Morphological Characteristics1
TLDR
Using morphological characteristics of both species growing naturally along a sand dune/forest ecotone, models confirmed that the two species can be discriminated effectively using fruit characters, notably fruit volume and seed number, and determined that at leaf out in the spring the leaves of the twospecies were folded differently in the bud allowing them to be successfully discriminated in the early spring.

Experimental field comparison of native and non‐native maple seedlings: natural enemies, ecophysiology, growth and survival
TLDR
Experimental field comparison with ecologically successful native trees provides insight into why non-native trees succeed as seedlings, which is a necessary stage on their journey into the forest canopy. Expand

Simulating forest shade to study the developmental ecology of tropical plants: juvenile growth in three vines in India
TLDR
A method for constructing shade enclosures to study the relative contributions of lowered photosynthetic photon flux density (PPFD) versus altered spectral distributions (R:FR) of radiation underneath vegetation canopies and its effects on developmental ecology of tropical forest plants is described. Expand
Photosynthetic acclimation of the liana Stigmaphyllon lindenianum to light changes in a tropical dry forest canopy
TLDR
Stigmaphyllon responded rapidly to light changes through the functional adjustment of already expanded foliage and an increase in leaf production in places with high opportunity for carbon gain, reflected in an almost immediate ability to respond to significant changes in light. Expand
Survival, Growth and Gas Exchange of Celastrus orbiculatus Seedlings in Sun and Shade
TLDR
The ability of C. orbiculatus to survive under deep shade despite its slow growth implies that intact forests are vulnerable to invasion and that established understory populations should be controlled before harvesting or thinning the forest. Expand
Fruit Fate, Seed Germination and Growth of an Invasive Vine – an Experimental Test of ‘sit and Wait’ Strategy
TLDR
Results show that most (>75%) C. orbiculatus seeds are dispersed, seedlings can establish in dense shade, and plants grow rapidly when exposed to high light conditions. Expand
Effects of irradiance and spectral quality on seedling development of two Southeast Asian Hopea species
TLDR
The seedling development of two Southeast Asian dipterocarp trees in response to differences in irradiance and spectral quality and the growth of this taxon may be constrained by adaptations, particularly in leaves, for drought tolerance. Expand
A systematic relationship between phytochrome-controlled development and species habitat, for plants grown in simulated natural radiation
TLDR
A survey of the responsiveness of plant species to simulated natural shade-light quality has demonstrated a systematic relationship between habitat and certain developmental responses, and in most cases the relationship between developmental response and the estimated phytochrome photoequilibrium is linear.

Effects of irradiance and spectral quality on leaf structure and function in seedlings of two Southeast Asian Hopea (Dipterocarpaceae) species.
TLDR
Variation in leaf anatomy is most likely a consequence of increasing leaf thickness in both taxa, which may increase mechanical strength and defense against herbivory in more exposed environments, and greater plasticity of leaf responses in H. odorata helps explain the acclimation over the range of light conditions encountered by this shade-tolerant taxon.

Shade Promotes Thorn Development in a Tropical Liana, Artabotrys hexapetalus (Annonaceae)
TLDR
It is concluded that the fate of lateral bud development is controlled by irradiance (light level) but not by light quality, which could be advantageous to plants growing in the deep shade of rain forests. Expand

TLDR
Morphological traits such as petiole length, leaf blade characteristics and investment patterns into spacers showed high degrees of shade-induced plasticity in both Potentilla anserina and P. reptans, while production parameters were most responsive to changes in light quantity. Expand
