TRENDS IN OSTRACODA AND CLADOCERA DISTRIBUTION AND WATER CHEMISTRY IN SUBARCTIC CANADA: CHURCHILL (MANITOBA) LAKES AND PONDS REVISITED

Trends in Ostracoda and Cladocera distribution and water chemistry in subarctic Canada: Churchill (Manitoba) lakes and ponds revisited

Ponds and lakes distributed across northern treeline in the Hudson Bay Lowlands near Churchill (Manitoba) were SOAP DISH revisited to analyse and document the local ecoclimatic and limnological changes that occurred over the period 1997-2012.Our analyses revealed that single events may cause significant changes in salinity, pH and silicate content

Short-Term Response of Instream Habitats and Brown Trout (Salmo trutta) Populations to Habitat Rehabilitation in Two Trout Streams, Minnesota, USA

Efforts to rehabilitate habitats in trout streams are common, but the pre-and post-project monitoring of impacts has Fender Flares produced conflicting results.Consequently, long-term monitoring plans were established for the reaches of two streams in southeastern Minnesota, USA, that were planned for rehabilitation.Instream habitats and brown trou

Dark matter self-interactions from spin-2 mediators

Abstract We propose a new mechanism for rendering dark matter self-interacting in the presence of a massive spin-2 mediator.The derived Yukawa-type Wall Mirror potential for dark matter is independent of the spins of dark matter in the leading order of the momentum expansion, so are the resulting non-perturbative effects for the dark matter self-sc
