Evaluation of a Decade of Methane Observations From a Tower Network in Indianapolis, Indiana

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract Methane (CH4) is a critical near‐term climate mitigation target, yet urban sources remain poorly constrained. Indianapolis hosts one of the world's longest and densest urban CH4 data sets, with continuous measurements from a tall‐tower network spanning more than a decade.

Non‐Additive Interactions Between Multiple Mutualists and Host Plant Genotype Simultaneously Promote Increased Plant Growth and Pathogen Defence

open access: yesPlant, Cell &Environment, Volume 49, Issue 7, Page 4134-4151, July 2026.
ABSTRACT Understanding the impact of microbial interactions on plants is critical for maintaining healthy native ecosystems and sustainable agricultural practices. Despite the reality that genetically distinct plants host multiple microbes of large effect in the field, it remains unclear the extent to which host genotypes modulate non‐additive ...

Phytoplankton growth and potential cyanotoxin production differ in response to nitrogen and phosphorus amendments in late summer communities from Kabetogama Lake (Minnesota, United States)

open access: yesJournal of Phycology, Volume 62, Issue 3, Page 883-903, June 2026.
Abstract Cyanotoxins such as microcystin (MC), cylindrospermopsin, and saxitoxin are secondary metabolites that are rich in nitrogen (N). Most cyanobacteria grow best on reduced inorganic N (ammonium, NH4), but when NH4 is absent, cyanobacteria can activate physiological pathways to process other N forms (e.g., nitrate; NO3).
