WHIGHAM, D. 1984. The influence of vines on the growth of Liquidambar styraciflua L. (sweetgum). Can. J. For. Res. 14: 37-39. The effect of vines on diameter growth of Liquidambar styraciflua L. (sweetgum) in a 40-year-old abandoned field was measured by vine removal experiments. Removal of vines from the trunk, branches, and ground had a significant positive effect on growth during each of the...

Previous surveys of vineyards had indicated that Mesocriconema xenoplax was present in 85% of vineyards in western Oregon, but yields were not depressed in established vines. Microplot studies were initiated in 1997 in a Willamette Valley vineyard to determine the impact of M. xenoplax on vine establishment. Plots were infested with 0.03, 0.6, and 3.0 M. xenoplax g soil and planted with self-ro...

BACKGROUND The potential of systemic neonicotinoid insecticides to control potato leafhopper, Empoasca fabae (Harris), a damaging pest of wine grapes in the eastern United States, was investigated. Soil or foliar applications were made to potted or field-grown vines, and the response of leafhoppers was determined in clip cages over the following month on young or mature leaves. RESULTS Foliar...

Bud necrosis (BN) of grape is observed as an abortion and drying of one or more primordia of the developing compound winter bud. The causes are uncertain, but high vigor, and canopy shade increase BN incidence under some conditions. This work was conducted to determine if localized carbohydrate or mineral nutrient deprivation increased the incidence of BN observed with ‘Riesling’ grapes in Virg...

Japanese black bears often break branches when climbing trees and feeding on fruit in canopies, thereby creating small canopy gaps. However, the role of black bear-created canopy gaps has not been evaluated in the context of multiple forest dynamics. Our hypothesis was that small canopy gaps created by black bears improve light conditions, which facilitates fruiting of adult fleshy-fruited plan...

Mimicry refers to adaptive similarity between a mimic organism and a model. Mimicry in animals is rather common, whereas documented cases in plants are rare, and the associated benefits are seldom elucidated [1, 2]. We show the occurrence of leaf mimicry in a climbing plant endemic to a temperate rainforest. The woody vine Boquila trifoliolata mimics the leaves of its supporting trees in terms ...

Copulas and vines allow us to model the distribution of multivariate random variables in a flexible way. This article introduces copulas via Sklar’s theorem, explains how pair copula constructions are built by decomposing multivariate copula densities and illustrates vine graphical representations.

Introduction classically, cell signalling has been viewed in terms of linear pathways that lead from external or internal stimuli to cellular effectors. But this simple view developed more as a means to visualize and to understand the individual components of these complex systems, rather than to reflect reality. it is now clear that, in most cases, cell signalling is much more complex and invo...

Strawberry fruits (Fragaria vesca) are valued for their sweet fruity flavor, juicy texture, and characteristic red color caused by anthocyanin pigments. To gain a deeper insight into the regulation of anthocyanin biosynthesis, we performed comparative metabolite profiling and transcriptome analyses of one red-fruited and two natural white-fruited strawberry varieties in two tissues and three ri...
