Abstract Animal dung analyses are a useful tool for vegetational studies. Preserved ruminant from archaeological layers offers unique possibility the reconstruction of past fodder management strategies, and further studying impact acquisition pasturing on forests. In this case study we investigate Late Neolithic livestock keeping forest around “Mooswinkel” pile dwelling at Austrian lake Mondsee...

The light stimulation of cold acclimation of Hedera helix L. var. Thorndale has been shown to result in the production of translocatable promoters of hardiness. Movement of the promoters from an illuminated donor portion to a darkened receptor portion was demonstrated. The majority of transport was acropetal through the phloem and to a much lesser degree basipetal through the xylem. In the earl...

Several anti-influenza drugs that reduce disease manifestation exist, and although these drugs provide clinical benefits in infected patients, their efficacy is limited by the emergence of drug-resistant influenza viruses. In the current study, we assessed the therapeutic strategy of enhancing the antiviral efficacy of an existing neuraminidase inhibitor, oseltamivir, by coadministering with th...

A survey of 27 herbaceous and woody plant taxa was conducted to identify possible alternative hosts of the xylem-limited bacterium, Xylellafastidiosa.
