TL;DR: Trematode prevalence appears to be predominantly determined by local site characteristics favoring high gull abundance, and formal analyses detected no regional spatial gradients in either trematode prevalence or independent environmental variables.

TL;DR: Oyster aquaculture has less than 0.5% of the GHG-cost of beef, small ruminants, pork, and poultry in terms of CO2-equivalents per kg protein, suggesting that shellfish aquacculture may provide a a low GHG alternative for future animal protein production compared to land based sources.

TL;DR: Understanding the dynamic nature of environmental releases of point and non-point sources of nutrients and trace metals in mixed agricultural systems using riverine water chemistry is complicated by changes in climatic conditions, highlighting the need for long-term monitoring of nutrients, river flows and weather data in assessing these agricultural sectors.

TL;DR: This study examines how atmospheric CO2 enrichment and N fertilization affects the uptake of silicon (Si) in the Duke Forest, North Carolina, a stand dominated by Pinus taeda (loblolly pine), and five hardwood species to calculate forest Si uptake rates under control and elevated CO2 concentrations.

TL;DR: Investigation of the Detroit River found spatial variation consistent with multiple sources including synthetic and manure-derived fertilizers and wastewater effluent, and the use of multiple tracer approaches will increase the ability to effectively manage aquatic ecosystems.
