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…]

The Arizona Game and Fish Department (AZGFD) will soon deliver nearly 3 million gallons of life-saving water to some of the state’s most vulnerable residents — herds of elk, bighorn sheep, bison, and other animals — as already severe drought conditions intensify.

The department plans to carry the unprecedented amount of water this year to 3,000 water catchment sites, or man-made watering holes that can hold between … [more…]

California: homeowners’ tax break to capture rainwater in their backyards

California homeowners could get a tax break to capture rainwater in their backyards

It was raining and Judy Adler had a broken gutter. What could have been a simple repair turned into an effort to capture rain and use it for her backyard pond.

Since late 2009, Adler has collected up to 11,000 gallons of rain annually at her Walnut
