Field-grown transgenic switchgras (Panicum virgatum L.) with altered lignin does not affect soil chemistry, microbiology, and carbon storage potential (open access)

Field-grown transgenic switchgras (Panicum virgatum L.) with altered lignin does not affect soil chemistry, microbiology, and carbon storage potential

This article describes a study to evaluate effects of two independent lines of caffeic acid O-methyltransferase (COMT) downregulated switchgrass plants on soils in terms of chemistry, microbiolgy, and carbon cycling when grown in the field.

Elevated CO2 increases energetic cost and ion movement in the marine fish intestine (open access)

Elevated CO2 increases energetic cost and ion movement in the marine fish intestine

Article describes study which aimed to gain resolution in assessing the energetic demand associated with acid-base regulation by examining ion movement and O2 consumption rates of isolated intestinal tissue from Gulf toadfish acclimated to control or 1900 μatm CO2 (projected for year 2300).
