Interplanetary frontiers: terraforming from an invasion science perspective
Oikos, EarlyView.The pursuit of a multi‐planetary existence represents one of humanity's greatest frontiers. If applied justly, it offers an opportunity to extend its civilization's lifespan amid escalating sustainability crises on Earth. One approach increasingly gaining traction is terraforming, a hitherto theoretical ecological and evolutionary experiment revolving ...

The Rumen methanogen community and diurnal activity in pasture based dairy cows of the South Island [PDF]
, 2012 The South Island of New Zealand offers a novel medium for studying methanogen community because dairy cows are fed almost exclusively on pasture and yet have unusually high milk production due to high dry matter intakes from high quality pastures.

Exploring rumen methanogen genomes to identify targets for methane mitigation strategies
, 2011 Methane emissions from ruminant livestock is generated by the action of methanogenic archaea, mainly in the rumen. A variety of methanogen genera are responsible for CH4 production, including a large group that lacks cultivated representatives.

Integrative Zoology, EarlyView.We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...

Integrative Zoology, EarlyView.Seasonal and regional dietary variation in Przewalski's gazelle was linked to coordinated changes in gut microbiota, functional pathways, and fecal metabolites. Winter diets featured Poaceae, Cyperaceae, and Iridaceae, whereas summer diets shifted toward forb families.

Supplementing beef cattle diets with brown seaweed affects coprophagous beetles' dung use
Agricultural and Forest Entomology, EarlyView.Supplementing beef cattle diets with brown seaweed reduced the attractiveness of dung for a common dung beetle (Onthophagus nuchicornis). Dietary supplementation with brown seaweed appeared to reduce the proportion of major males in the F1 generation.

The impact of sludge amendment on methanogen community structure in an upland soil
In the EU, municipal sewage sludge application to agricultural land has increased dramatically since the ban on dumping at sea came into effect in 1998. There are many concerns related to potential contamination and reduction in plant productivity.

Prebiotic aqueous reactions catalyzed by native nickel without hydrogen
The FEBS Journal, EarlyView.Serpentinizing (H2‐producing) hydrothermal vents are candidate environments for metabolic origin. They generate highly reducing conditions that convert CO2 to formate and methane in abiotic reactions resembling reactions of the acetyl‐CoA pathway of CO2 fixation. They also contain natural catalysts. Native nickel (Ni0), like Fe0, Co0, and their alloys,

Delivering Sulfate to LNAPL Body for Enhanced Source Zone Depletion (ESZD)
Groundwater Monitoring &Remediation, EarlyView.Abstract This field pilot study evaluates the feasibility of applying sulfate to a light non‐aqueous phase liquid (LNAPL) body for achieving enhanced source zone depletion (ESZD) at a refinery site. Two rounds of gypsum land application (GLA) delivered sulfate to an 8000 ft2 area encompassing LNAPL‐containing monitoring wells MW‐2 and MW‐3, while MW‐1 ...
