During the period of 2011–2018, average specific activity 90Sr in aboveground organs prairie cordgrass, submerged club-rush, common reed, and narrow-leaved cattail ranged from 1.5 to 14.0 Bq/kg, while 137Cs 3.1 165 Bq/kg. Over course study, a tendency towards decrease accumulation levels by hydrophytes was observed. The helophytes likely remained unchanged. In 2018, investigated plant species d...

Abstract Invasive plant species can alter natural communities and degrade ecosystem function, yet the factors influencing invasion are poorly understood. The purpose of this study was to characterize environmental drivers community structure invasive prevalence within invaded portions wetland mitigation sites. We sampled vegetation variables (prevalence index, light availability, soil physioche...

Alternative food sources could sustain predator populations by influencing their performances including predation, development, and reproduction in periods of shortage or scarcity prey under laboratory fields conditions. The aim this study was to explore suitability cattail pollen (Typha orientalis) as an alternative source for different stages Amblyseius herbicolus (Chant) (Acari: Phytoseiidae...

Paludiculture, the cultivation of crops on rewetted peatlands, is often proposed as a viable climate change mitigation option that reduces greenhouse gas emissions (GHGe), while simultaneously providing novel agricultural business options. In West Europe, experiments are ongoing in using paludicrop cattail (Typha spp.) feedstock for insulation panel material. Here, we use Dutch case study to in...

Mining activity produces metal sulfide wastes particularly pyrite which remain in the mine long after operations cease. When water percolates through a mine where oxygen is present, a series of chemical reactions occur which produce extremely low pH and high concentrations of toxic sulfate and metal ions. This toxic leachate can cause severe aquatic habitat degradation downstream of the mine. T...

Wetland soils are heterogenous in nature, and biogeochemical properties show different spatial autocorrelation structures that translate into fineand coarse-scale spatial patterns. Understanding these patterns and how they relate to other ecosystem properties (e.g., vegetation) is critical to restore wetlands impacted by nutrient influx. Our goal was to investigate Water Conservation Area 2A, a...

In metapopulations in which habitat patches vary in quality and occupancy it can be complicated to calculate the net time-averaged contribution to reproduction of particular populations. Surprisingly, few indices have been proposed for this purpose. We combined occupancy, abundance, frequency of occurrence, and reproductive success to determine the net value of different sites through time and ...

Pot experiments were conducted to study the potential of T. angustifolia plants for Cr, Cd and Pb toxicity on the ultrastructure, Reduced Glutathione (GSH) and Free Cysteine on T. angustifolia (Narrow Cattail) after 30 d exposure of 1 mM Cr, Cd or Pb. Cr, Cd and Pb toxicity stress distort the ultrastructure and the treated seedlings showed that the vacuoles were expanded and endoplasmic membran...
