The Tambov region is located in a forest-steppe natural zone, which characterized by relatively low paludification and strong transformation of landscapes. In the XX century, mires were subjected to significant anthropogenic impact, affected flora, but was practically not recorded publications last three decades. article presents results floristic studies Region conducted 2011–2021.

As a part of our studies on the biologically active substances from Spanish plants, we have undertaken an investigation of the chemical constituents of a typical mediterranean species, Phillyrea latifolia L. (Oleaceae). Two secoiridoid glycosides, three phenylpropanoid glycosides, one lignane and two triterpenic acids were isolated from the leaves of this species and identified. The phytochemic...
Abstract Sea-level rise intensifies saltwater influx into coastal wetlands causing osmotic stress and probably changing vegetation composition. To determine especially the impact of salinity pulses that occur during flooding events, Typha latifolia , Carex acutiformis Schoenoplectus tabernaemontani Phragmites australis were exposed to different regimes consisting control (permanently freshwater...
Cattail or Typha, an emergent aquatic macrophyte widely distributed in lakes and other shallow water areas, has slender blades with a chiral morphology. The wind-resilient Typha blades can produce distinct hydraulic resistance for ecosystem functions. However, their stem may rupture and dislodge in excessive wind drag. In this paper, we combine fluid dynamics simulations and experimental measur...
تالاب شادگان یکی از مهمترین و ارزشمندترین زیستگاههای آبی کشور است که از نظر زیستشناختی و بومشناختی اهمیت زیادی در حیاتوحش منطقه دارد. به منظور ارزیابی گونههای گیاهی به عنوان اندامگان نشانگر آلودگی فلزات سنگین در مطالعات زیستپایشی بومسامانه آبی، در این پژوهش انباشت فلزات سنگین(مولیبدن، مس، سرب، روی، آرسنیک، سلنیم، جیوه، نیکل، کبالت، کادمیم، کروم، وانادیم، منگنز، آلومینیم و آهن) در ریشه و ...
