Global Change Biology > 30 > 6 > n/a - n/a

The Earth functions as an integrated system—its current habitability to complex life is an emergent property dependent on interactions among biological, chemical, and physical components. As global warming affects ecosystem structure and function, so too will the biosphere affect climate by altering atmospheric gas composition and planetary albedo. Constraining these ecosystem‐climate feedbacks is...

Rashaduz Zaman, Aftab Shah, Ateeq Shah, Aziz Ullah, more

Global Change Biology > 30 > 3 > n/a - n/a

Mountain pine beetles (MPBs) pose a substantial threat to North American pine forests, causing extensive tree mortality over large areas. Their tree‐killing ability is closely linked to mass aggregation on host trees triggered via pheromones and dependence on their symbiotic fungi. However, the influence of a changing climate on the biology of MPBs and their co‐evolved interactions with their fungal...

Recent increases in annual, seasonal, and extreme methane fluxes driven by changes in climate and vegetation in boreal and temperate wetland ecosystems

Sarah Feron, Avni Malhotra, Sheel Bansal, Etienne Fluet‐Chouinard, more

Global Change Biology > 30 > 1 > n/a - n/a

Climate warming is expected to increase global methane (CH₄) emissions from wetland ecosystems. Although in situ eddy covariance (EC) measurements at ecosystem scales can potentially detect CH₄ flux changes, most EC systems have only a few years of data collected, so temporal trends in CH₄ remain uncertain. Here, we use established drivers to hindcast changes in CH₄ fluxes (FCH₄) since the early 1980s...

Size matters: Aerobic methane oxidation in sediments of shallow thermokarst lakes

Rinat Manasypov, Lichao Fan, Artem G. Lim, Ivan V. Krickov, more

Global Change Biology > 30 > 1 > n/a - n/a

Shallow thermokarst lakes are important sources of greenhouse gases (GHGs) such as methane (CH₄) and carbon dioxide (CO₂) resulting from continuous permafrost thawing due to global warming. Concentrations of GHGs dissolved in water typically increase with decreasing lake size due to coastal abrasion and organic matter delivery. We hypothesized that (i) CH₄ oxidation depends on the natural oxygenation...

F. Asch, K. Johnson, T. B. T. Vo, B. O. Sander, more

Journal of Agronomy and Crop Science > 209 > 6 > 876 - 886

Alternate wetting and drying irrigation (AWD) has been shown to decrease water use and trace gas emissions from paddy fields. Whereas genotypic water use shows little variation, it has been shown that rice varieties differ in the magnitude of their methane emissions. Management and variety‐related emission factors have been proposed for modelling the impact of paddy production on climate change; however,...
