Fresh, potable water is an everyday miracle in the middle of the Pacific Ocean. To have enough to supply millions with (relatively) few constraints on usage? It’s almost unimaginable. And, perhaps, too precarious to want to imagine.

Of course, the water in Hawai’i serves more than latecomer humans. Endemic land species of every kind, exotic imports, and unique hybrids do not spring from saltwater. … [more…]

You will never hear the words “water crisis” said aloud in the in the chambers of the Arizona Legislature, Salt River Project, or Central Arizona Project. The fact the reservoirs on the Colorado River, which store irrigation water for our farms, have hit their lowest levels has not prompted our state’s Department of Agriculture, nor Farm Bureau to say the word “crisis” in public.

Forest defoliator outbreaks alter nutrient cycling in northern waters

Forest defoliator outbreaks alter nutrient cycling in northern waters

Abstract

Insect defoliators alter biogeochemical cycles from land into receiving waters by consuming terrestrial biomass and releasing biolabile frass. Here, we related insect outbreaks to water chemistry across 12 boreal lake catchments over 32-years. We report, on average, 27% lower dissolved organic carbon (DOC) and 112% higher dissolved inorganic nitrogen (DIN) concentrations in lake waters when defoliators covered entire catchments and reduced leaf area. DOC reductions reached 32% when deciduous … [more…]
