Weeds in a changing climate: Competitors or service plants?

PLANTS, PEOPLE, PLANET, EarlyView.
Reducing herbicide use and preparing agroecosystems for climate change are two top priorities on the global policy agenda. Here, we explore whether these two challenges can be tackled simultaneously. While weeds are generally considered a threat to crop production, we show that weeds can help overcome climate change challenges in agroecosystems ...

The nitrogen removal characterization and ecological risk assessment of Bacillus sp. isolated from mariculture systems in China with spatiotemporal difference.

PLoS ONE
The accumulation of nitrogen compounds may worsen the aquatic environment and cause serious economic losses in the aquaculture industry. In this study, the denitrification performance and ecological safety of 120 Bacillus sp.

Increased Denitrification Rates Associated with Shifts in Prokaryotic Community Composition Caused by Varying Hydrologic Connectivity

Frontiers in Microbiology, 2017
While modern developments in agriculture have allowed for increases in crop yields and rapid human population growth, they have also drastically altered biogeochemical cycles, including the biotransformation of nitrogen.

Activity and abundance of denitrifying bacteria in the subsurface biosphere of diffuse hydrothermal vents of the Juan de Fuca Ridge [PDF]

, 2012
Little is known about fixed nitrogen (N) transformation and elimination at diffuse hydrothermal vents where anoxic fluids are mixed with oxygenated crustal seawater prior to discharge.

Climate‐smart land management: Greenhouse gas outcomes and social and economic pathways to adoption

PLANTS, PEOPLE, PLANET, EarlyView.
Climate change poses one of the greatest threats to natural and working lands, reducing the resilience of agricultural and forest productivity. Because land management is a leading source of greenhouse gas (GHG) emissions, climate‐smart management practices are being implemented to reduce net emissions while sustaining yields.

Screening and nitrogen removal characteristics of a denitrifying bacteria suitable for partial denitrification

Gongye shui chuli
A strain D5 with excellent partial denitrification performance was screened from paddy soil. The bacteria were identified as Klebsiella pneumoniae by morphological observation and 16S r DNA sequence analysis.

Intermittent flooding of organic‐rich soil promotes the formation of denitrification hot moments and hot spots

Ecosphere, 2019
Anthropogenic activities have altered the nitrogen cycle, necessitating management on the landscape level. Isolated time periods and areas, termed hot moments and hot spots, respectively, frequently account for a large percentage of nitrate removal in ...

Environmental Stressors Influence Spatial Complexity in a Fluvial Macrophyte meadow

Remote Sensing in Ecology and Conservation, EarlyView.
This research investigates the nonlinear relationships between environmental stressors and the fine‐scale spatial complexity of a fluvial macrophytes meadow. The use of multivariate spatial analysis allowed us to identify two major environmental gradients (nutrients and light) and two major complexity gradients (related to abundance and fragmentation).

A Critical Review on Nitrogen Control in the Scrap‐Based Electric Arc Furnace Steelmaking Route to Produce Low‐Nitrogen Steels

steel research international, EarlyView.
In primary electric arc furnace (EAF) steelmaking, carbon boiling removes nitrogen from liquid steel and sustains slag foaming. In 100% scrap‐ or hydrogen direct reduced iron (HDRI)‐based EAF steelmaking, carbon boiling is absent; therefore, carbonaceous material and oxygen injection into the slag is needed to maintain foaming and avoid nitrogen ...

Integrating large mammalian herbivores into Dynamic Global Vegetation Models: Status and next steps

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Zoogeochemistry, the study of how animals influence elemental cycling within ecosystems, bridges the fields of zoology, ecology and biogeochemistry. Yet, most terrestrial ecosystem models, especially Dynamic Global Vegetation Models (DGVMs), remain largely plant‐centric
