A neophyte for the Valencian flora, Bladder dock (Rumex vesicarius, L.), is reported. The species was found at lowlands in the surroundings of Sagunto (Valencia), close to the Mediterranean Sea. Plants formed a single population with 131 individuals occupying 4.7 ha. A brief description of the...

Many Polygonaceae are primary successors or "weedy" and Aconogonon polystachyum and species and hybrids of both Emex and Reynoutria are pernicious invasives outside their native ranges. Polygonaceae have a particularly muddled taxonomic history and despite ongoing systematic studies, there are...

Alien species expand their distribution by transportation network development. Hybridization between alien species Rumex obtusifolius and closely related native vulnerable species R. longifolius was examined in a mountain tourist destination in central Japan. The three taxa were morphologically...

The paper presents the spontaneous vascular flora and the flora originating from old or contemporary plantations found in all six currently existing cemeteries located in immediate vicinity on the slopes of the Cytadela Park in Poznań. These studies were carried out in the years 2011-2014. Over...

Semiarid grasslands in NW Patagonia (Argentina) are dominated by Festuca pallescens and Pappostipa speciosa, two native tussock grasses that differ in water stress tolerance and in palatability to livestock. Both species regenerate in gap microsites invaded by the exotic herb Rumex acetosella. We...

Background: Sarma - cooked leaves rolled around a filling made from rice and/or minced meat, possibly vegetables and seasoning plants - represents one of the most widespread feasting dishes of the Middle Eastern and South-Eastern European cuisines. Although cabbage and grape vine sarma is...

Studies on alpine and semi-arid environments indicate that plants that act as ecosystem engineers improve microhabitat conditions and modify local plant abundance and diversity. However, few studies have linked these patterns with the physiological responses of associated species. We analyze the...

To understand alterations of oxalate and other metabolite levels induced by aluminium ion (Al³⁺) stress in Rumex plants, we measured the metabolites in R. obtusifolius using the capillary electrophoresis-mass spectrometry. Oxalate and its precursors (isocitrate and citrate) accumulated in leaves of ...

Analysis of organic acids has become increasingly important due to their role in the physiological activity of plants, and many separation methods have been developed for the simultaneous determination of these compounds in plant samples. Herein, ultra fast liquid chromatography and photodiode...

Management methods to control or eradicate invasive alien species should be guided by research into their efficacy in relation to the target species as well as their wider effects on the community. Impatiens glandulifera Royle (Balsaminaceae) is an invasive alien species, which has spread rapidly...
