SNAPSHOT USA 2024: Year 6 of the Coordinated National Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multi‐contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of speci...
Effect of in situ CO2 mixing of cement paste on the leachability of hexavalent chromium (Cr(VI))NARA Subscribed
In situ CO 2 mixing technology is a potential technology for permanently sequestering CO 2 during concrete manufacturing processes. Although it has been approved as a promising carbon capture and utilisation (CCU) method, its effect on the leachability of heavy metals from cementitious compounds has not yet been studied. This study focuses on the effect of in situ CO 2 mixing of cement paste on the leaching of hexavalent chrom...
SNAPSHOT USA 2021: A third coordinated national camera trap survey of the U nited S tatesNARA Subscribed
SNAPSHOT USA is a multicontributor, long‐term camera trap survey designed to survey mammals across the United States. Participants are recruited through community networks and directly through a website application ( https://www.snapshot-usa.org/ ). The growing Snapshot dataset is useful, for example, for tracking wildlife population responses to land use, land cover, and climate changes across spatial and temporal scales. Her...
Summary Acetogenic bacteria are already established as biocatalysts for production of high‐value compounds from C1 substrates such as H 2 + CO 2 or CO. However, little is known about the physiology, biochemistry and bioenergetics of acetogenesis from formate, an interesting feedstock for biorefineries. Here, we analysed formate metabolism in the model acetogen Acetobacterium woodii . Cells grew optimally on 200 mM formate to a...
Growth of the acetogenic bacterium Acetobacterium woodii on glycerol and dihydroxyacetoneNARA Subscribed
Summary More than 2 million tons of glycerol are produced during industrial processes each year and, therefore, glycerol is an inexpensive feedstock to produce biocommodities by bacterial fermentation. Acetogenic bacteria are interesting production platforms and there have been few reports in the literature on glycerol utilization by this ecophysiologically important group of strictly anaerobic bacteria. Here, we show that the...
Seeing the forest for the trees: long‐term exposure to elevated CO 2 increases some herbivore densitiesNARA Subscribed
The effects of elevated CO 2 on plant growth and insect herbivory have been frequently investigated over the past 20 years. Most studies have shown an increase in plant growth, a decrease in plant nitrogen concentration, an increase in plant secondary metabolites and a decrease in herbivory. However, such studies have generally overlooked the fact that increases in plant production could cause increases of herbivores per unit...
Elevated CO 2 increases the long‐term decomposition rate of Quercus myrtifolia leaf litterNARA Subscribed
Decomposition of Quercus myrtifolia leaf litter in a Florida scrub oak community was followed for 3 years in two separate experiments. In the first experiment, we examined the effects CO 2 and herbivore damage on litter quality and subsequent decomposition. Undamaged, chewed and mined litter generated under ambient and elevated (ambient+350 ppm V) CO 2 was allowed to decompose under ambient conditions for 3 years. Initial litt...
