These varied and rich herbaceous assemblages differed among site types, and sorted according to influences including apparent human restriction of vegetation growth, wetness, and surrounding land use. These results suggest that management can nudge agricultural and freeway ditch herbaceous communities to ...

Using a 30-year-old reciprocal transplant study across a 475km latitudinal gradient, we tested the adaptational lag hypothesis by measuring both short-term (tiller population growth rates) and long-term (17-year survival) fitness components of Eriophorum vaginatum ecotypes in Alaska, where climate...
of different type of dyes (basic, acidic, reactive) from water and wastewater as potential alternatives to activated carbons has recently received widespread attention because of the environmental-friendly nature of clay materials. Insights into the efficiencies of raw and modified/activated clay ...
