Restoring soil and tree nutrition through non‐industrial wood ash additions to sugarbushes Open
Nutrient losses from forest soils caused by decades of acid deposition have affected tree growth and depleted soils of essential nutrients in eastern North America. Non‐industrial wood ash (NIWA) is rich in macronutrients and may be a pote…

Macronutrients, metals, and metalloid concentrations in non-industrial wood ash in relation to provincial land application limits in Ontario, Canada Open
Non-industrial wood ash (NIWA) provided by residents who heat with wood, is rich in base-cations and other nutrients and may be used as a forest soil amendment to return nutrients lost through acid deposition. However, due to concerns rega…

A lake management framework for global application: monitoring, restoring, and protecting lakes through community engagement Open
Despite decades of management and regulation, global freshwater resources remain imperiled. Management has had mixed success in restoring degraded lakes and has few mechanisms for stopping the decline of high-quality systems. Too often, la…

<i>Daphnia</i> as a Sentinel Species for Environmental Health Protection: A Perspective on Biomonitoring and Bioremediation of Chemical Pollution Open
Despite available technology and the knowledge that chemical pollution damages human and ecosystem health, chemical pollution remains rampant, ineffectively monitored, rarely prevented, and only occasionally mitigated. We present a framewo…

Wood ash amendments as a potential solution to widespread calcium decline in eastern Canadian forests Open
Decades of acidic deposition have depleted soil calcium (Ca) stocks over large areas of eastern Canada. The recovery of soil Ca levels has been limited despite substantial reductions in acidic deposition and will likely take many decades b…

Climate warming restructures an aquatic food web over 28 years Open
Climate warming can restructure lake food webs if trophic levels differ in their thermal responses, but evidence for these changes and their underlying mechanisms remain scarce in nature. Here we document how warming lake temperatures by u…

Could a residential wood ash recycling programme be part of the solution to calcium decline in lakes and forests in Muskoka (Ontario, Canada)? Open
One possible solution to the recent decline of calcium (Ca) concentrations in Canadian Shield forests and lakes in eastern North America is the addition of Ca-rich wood ash to watersheds. We investigated the feasibility of using small, mai…
View article: Calcium and sodium as regulators of the recovery of four Daphnia species along a gradient of metal and base cations in metal contaminated lakes in Sudbury, Ontario, Canada
Calcium and sodium as regulators of the recovery of four Daphnia species along a gradient of metal and base cations in metal contaminated lakes in Sudbury, Ontario, Canada Open
Smelting of sulphur-rich metallic ores in Sudbury, Ontario, Canada, has caused acidification and metal contamination of thousands of lakes in the region. Recent reductions in smelter emissions have resulted in much ecological recovery, but…

What have we learned about ecological recovery from liming interventions of acid lakes in Canada and Italy? Open
The idea of launching another special issue of the Journal of limnology on Lake Orta was born in 2014, on the 25th anniversary of its liming intervention, during an International symposium on Lake Orta organized and hosted by th…
View article: Past, present and future of the fish community of Lake Orta (Italy), one of the world’s largest acidified lakes
Past, present and future of the fish community of Lake Orta (Italy), one of the world’s largest acidified lakes Open
Since 1926, the fishes in Lake Orta, one of Italy’s deepest natural lakes, were heavily damaged by profundal hypoxia and acidification linked to oxidation of ammonia from industrial effluents and by industrial metal pollution. Of the origi…

Mechanisms underlying recovery of zooplankton in Lake Orta after liming Open
The goal of this study was to improve the understanding of the large-scale mechanisms underlying the recovery of the zooplankton of Lake Orta from historical contamination, following reduced input of ammonia and metals and the subsequent 1…

Arrive, survive and thrive: essential stages in the re-colonization and recovery of zooplankton in urban lakes in Sudbury, Canada Open
The recovery of lakes from severe, historical acid and metal pollution requires that colonists of extirpated species arrive, survive and subsequently thrive. We employed 40 year records from weekly to monthly crustacean zooplankton samples…

Predicting chronic copper and nickel reproductive toxicity to Daphnia pulex-pulicaria from whole-animal metabolic profiles Open
The emergence of omics approaches in environmental research has enhanced our understanding of the mechanisms underlying toxicity; however, extrapolation from molecular effects to whole-organism and population level outcomes remains a consi…

Planning for Climate Change in Muskoka: A Report from the Muskoka Watershed Council Open
Muskoka provides a wonderful environment in which to live, and that environment sustains a vibrant tourism and recreational economy worth approximately $400 million annually (roughly 55% of our total economy). Climate change is going to al…

Consequences of calcium decline on the embryogenesis and life history of <i>Daphnia magna</i> Open
Ambient calcium is declining in thousands of soft-water lake habitats in temperate regions as a consequence of unsustainable forestry practices, decreased atmospheric calcium deposition, and acidic deposition. As their exoskeleton is heavi…
