Moisture effects on microbial activity and community structure in decomposing birch litter in the Alaskan taiga
TL;DR: In this paper, the effect of moisture regime on microbial biomass and activity in birch litter in the Alaskan taiga was evaluated by placing litter bags in one of three different treatments: continuously moist (0.5 cm water d−1), cycling (0., 5 cm water weekly), and ''natural'' which experienced two natural dry-wet cycles of 2 weeks dry followed by rain.

Pesticides reduce symbiotic efficiency of nitrogen-fixing rhizobia and host plants
TL;DR: Previously undescribed in vivo evidence is shown that a subset of organochlorine pesticides, agrichemicals, and environmental contaminants induces a symbiotic phenotype of inhibited or delayed recruitment of rhizobia bacteria to host plant roots, which results in fewer root nodules produced, lower rates of nitrogenase activity, and a reduction in overall plant yield at time of harvest.

TL;DR: In this article, a conceptualization of climate-smart agriculture as agriculture that can be shown to bring us closer to safe operating spaces for agricultural and food systems across spatial and temporal scales is presented.
The climate policy narrative for a dangerously warming world
TL;DR: It is time to acknowledge that global average temperatures are likely to rise above the 2 °C policy target and consider how that deeply troubling prospect should affect priorities for communicating and managing the risks of a dangerously warming climate as mentioned in this paper.

Controls on Soil Carbon Dioxide and Methane Fluxes in a Variety of Taiga Forest Stands in Interior Alaska
Jay Gulledge,Joshua P. Schimel +1 more
TL;DR: In this article, the authors monitored CO2 and CH4 fluxes over 4 years in a range of taiga forests along the Tanana River in interior Alaska, and found that the biological processes driving CO2 fluxes were sensitive to temperature, moisture, and vegetation.
