Urban-use pesticides in stormwater ponds and their accumulation in biofilms

The paper investigates pesticide contamination in stormwater ponds and quantifies their accumulation in biofilms, finding that biofilms capture pesticides not detected in water samples.

Control of invasive Phragmites australis (European common reed) alters macroinvertebrate communities

This study evaluates the impact of invasive Phragmites australis control on macroinvertebrate communities in wetlands, finding herbicide treatment significantly alters community composition.

Invasive grass causes biotic homogenization in wetland birds

This study shows that invasion by Phragmites australis leads to homogenization of wetland bird communities, reducing taxonomic diversity and increasing nesting site similarity.

Wetland birds in the northern prairie pothole region may show sensitivity to agriculture.

The paper assesses how agricultural activity affects wetland bird assemblages in southern Alberta, finding that assemblages are specific to natural regions and agricultural landscapes support waterfowl and shorebirds.

Bioconcentration of glyphosate in wetland biofilms

The paper measures glyphosate bioconcentration in wetland biofilms and finds it is significantly higher than surrounding water, with potential implications for contaminant exposure.

Functional dispersion of wetland birds, invertebrates and plants more strongly influenced by hydroperiod than each other

The study uses functional dispersion to assess how hydroperiod influences bird, invertebrate, and plant communities in wetlands, finding hydroperiod has a stronger direct effect than biotic interactions.

Suppression of established invasive Phragmites australis leads to secondary invasion

This study evaluates the effectiveness of glyphosate herbicide in suppressing invasive Phragmites australis and assesses vegetation recovery, finding significant reduction in P. australis but secondary invasion by another non-native species.
