Sediments from Cheboygan Marsh, a coastal freshwater wetland on Lake Huron that has been invaded by an emergent exotic plant, Typha glauca, were examined to assess the effects of invasion on wetland nutrient levels and sediment microbial communities. Comparison of invaded and uninvaded zones of the marsh indicated that the invaded zone showed significantly lower plant diversity, as well as sign...

Due to the major environmental impact of peat-based growing media production and need lowering greenhouse gas emissions in all sectors, a wider application peat substitutes is requested. All under use have constraints associated with their properties. Therefore, preliminary test procedure for identifying new raw materials as was developed validated. By applying procedure, potential limitations ...

The fossil fuel-based linear economy has many severe drawbacks, including the need for energy security and resulting environmental degradation. In a new cycle of bio-economy that is becoming increasingly important, biomass waste been used to generate while reducing pollution greenhouse gas emissions. growth renewable will be substantial in reduction emissions order achieve ambitious goal carbon...

Interspecific hybridization can lead to a breakdown of species boundaries, and is of particular concern in cases in which one of the parental species is invasive. Cattails (Typha spp.) have increased their abundance in the Great Lakes region of North America over the past 150 years. This increase in the distribution of cattails is associated with hybridization between broad-leaved (Typha latifo...

Abstract Astigmatid mites can be used as prey for mass rearing of phytoseiid predators, but also a supplemental food source to support predator populations in crops. Here we evaluated the potential six species astigmatid (living or frozen) alternative predatory mite Amblyseius swirskii Athias-Henriot greenhouse All tested were suitable oviposition. In general, oviposition was greater when reare...
