Publikováno v: Great Lakes Institute for Environmental Research Publications

Introduced aquatic macrophytes can dominate small agricultural waterways in summer and autumn becoming a significant management problem. Excessive growth can clog waterways, causing drainage issues and reducing agricultural productivity while in-stre

Publikováno v: Great Lakes Institute for Environmental Research Publications

Excessive macrophytes can cause significant problems in agricultural waterways requiring active management. Conventional control techniques can have a range of adverse effects. We investigated several control tools in two experiments: firstly, we tes

Preservatives and sample preparation in stable isotope analysis of New Zealand freshwater invertebrates

Autor: Peter A. McHugh, Kristy L. Hogsden

Publikováno v: New Zealand Journal of Marine and Freshwater Research. 51:455-464

Interpretation of stable isotope data needs to take into account known, but often variable and inconsistent, influences of preservatives and lipids on carbon and nitrogen isotopic values. We tested how short-term (

Publikováno v: Great Lakes Institute for Environmental Research Publications

Excessive nutrient loading from small agricultural headwaters can substantially degrade downstream water quality and ecological conditions. But, our understanding of the scales and locations to implement nutrient attenuation tools within these catchm

Leaf litter additions enhance stream metabolism, denitrification, and restoration prospects for agricultural catchments

Autor: Kristy L. Hogsden, Helen J. Warburton, Catherine M. Febria, Jonathan M. O'Brien, Jon S. Harding, S. Elizabeth Graham, Angus R. McIntosh, Hannah M. Franklin

Publikováno v: Great Lakes Institute for Environmental Research Publications

Globally intensive agriculture has both increased nitrogen pollution in adjacent waterways and decreased availability of terrestrially derived carbon frequently used by stream heterotrophs in nitrogen cycling. We tested the potential for carbon addit

Isotopic metrics as a tool for assessing the effects of mine pollution on stream food webs

Autor: Kristy L. Hogsden, Jon S. Harding

Publikováno v: Ecological Indicators. 36:339-347

Most tools used to assess pollution impacts are based on structural, or less frequently, functional aspects of biotic communities. However, the application of measures that take a food web approach to understand the effects of stress on stream ecosys

Leaf breakdown, detrital resources, and food webs in streams affected by mine drainage

Autor: Jon S. Harding, Kristy L. Hogsden

Publikováno v: Hydrobiologia. 716:59-73

Breakdown of leaf litter is essential for providing detrital resources for food webs but can be impaired by anthropogenic activities, which may disrupt energy flow to consumers. We investigated the relationship between leaf breakdown and food web str

Publikováno v: Waterbirds. 35:13-22

Carolinian habitats on Middle Island in the western basin of Lake Erie have recently experienced a dramatic rise in nesting Double-crested Cormorants (Phalacrocorax auritus). Nesting cormorants on the 0.3 × 1.1 km island increased from three pairs i

Consequences of acid mine drainage for the structure and function of benthic stream communities: a review

Autor: Kristy L. Hogsden, Jon S. Harding

Publikováno v: Freshwater Science. 31:108-120

Streams affected by acid mine drainage (AMD) are highly stressed ecosystems and occur worldwide. These streams typically have low pH, high concentrations of dissolved metals, and substrata coated with metal hydroxide precipitates. This combination of
