A taxonomic revision of the Xiphinema americanum species complex has necessitated a reexamination of the host range of species in the complex before recommendations can be made with confidence on the likelihood that specific crops will be damaged. Toward this end, populations of X. americanum and X. rivesi collected from apple orchards in eastern and western New York state were evaluated after ...

Nep1 is an extracellular fungal protein that causes necrosis when applied to many dicotyledonous plants, including invasive weed species. Using transmission electron microscopy, it was determined that application of Nep1 (1.0 micro g mL(-)(1), 0.1% [v/v] Silwet-L77) to Arabidopsis and two invasive weed species, spotted knapweed (Centaurea maculosa) and dandelion (Taraxacum officinale), caused a...

UNLABELLED Communities of post-dispersal granivores can shape the density and dispersion of exotic plants and invasive weeds, yet plant ecologists have a limited perception of the relative trophic linkages between a seed species and members of its granivore community. Dandelion seeds marked with Rabbit IgG were disseminated into replicated plots in the recipient habitat (South Dakota) and the n...

In this paper, we review the peer-to-peer blockchain transaction protocol, Dandelion, and develop an oracle-based model for its network security. We formalize a series of security functional criteria, such as unforgeability, non-repudiation, immutability, into experiments. our model, consider quantum-capable adversary who seeks to undermine any criteria while using oracles simulate interact wit...

to examine metal content of dandelion plants in relation to environmental metal levels,concentrations of cd, hg and pb were analyzed in plant parts (leaves and roots) and soil samples from fivesites in the city of brno (czech republic), differentially impacted by pollution. soils and plants werecollected mid-april 2011. atomic absorption spectrometry was used to determine concentrations of thes...

The objective of the study was to evaluate the effect of inulin or dandelion, chicory and Jerusalem artichoke powder on lipid indices and fatty acid profile in fattener tissues. The experiment involved 120 crossbred pigs (PL x PLW) x Duroc with an initial body weight of 25.0 +/- 0.5 kg. Animals were assigned into 6 groups. A diet for group I (control) did not comprise an inulin additive, group ...

Flower visits are complex encounters, in which animals are attracted by floral signals, guided toward the site of the first physical contact with a flower, land, and finally take up floral rewards. At close range, signals of stamens and pollen play an important role to facilitate flower handling in bees, yet the pollen stimuli eliciting behavioral responses are poorly known. In this study, we t...
