Facilitated Transport of Organic Contaminants in a High Concentration, Multicomponent Plume
Groundwater Monitoring &Remediation, EarlyView.Abstract A field experiment evaluated the transport of organic contaminants in a plume from hazardous waste disposal areas at the Rocky Mountain Arsenal. The plume contained many xenobiotic contaminants, with widely varying expected mobilities.

Nitrogen excretion and oxygen consumption under severe hypoxia in siluriform fishes from the Amazon
Journal of Fish Biology, EarlyView.Abstract Siluriform fishes collected from the Rio Negro and Rio Solimões proved to be highly resistant to aquatic hypoxia. In all four species analysed in this study, aquatic oxygen consumption significantly decreased from normoxic levels at water PO2 values near 1 kPa. Air‐breathing activity was observed only in Sturisoma sp. (Rio Negro).

Journal of Fish Biology, EarlyView.Abstract This study aimed to investigate how exposure to elevated water temperature and metal concentration jointly affect the physiology of Amazonian fish. Aboard a research vessel in the Amazon, we evaluated the effects of water temperature (river T°C at 31.5°C and a + 4°C increase to 35.5°C) and of 3‐h copper (Cu) exposure (up to 600 μg/L) in ...

The Effects of Canning on the In Vitro Solubility of Phosphorus in Pet Food
Journal of Animal Physiology and Animal Nutrition, EarlyView.ABSTRACT Excess phosphate (P) intake through inorganic P (Pi) addition is known to cause various adverse health effects while declaration of use and amount in pet food in the EU is not regulated. Distinction between organic phosphate (oP) from feed ingredients and Pi with standard laboratory methods is impossible.

Restoring soil and tree nutrition through non‐industrial wood ash additions to sugarbushes
Restoration Ecology, EarlyView.Nutrient losses from forest soils caused by decades of acid deposition have affected tree growth and depleted soils of essential nutrients in eastern North America. Non‐industrial wood ash (NIWA) is rich in macronutrients and may be a potential remediation strategy to restore lost nutrients as a forest soil amendment.

Restoration Ecology, EarlyView.Abstract Introduction Climate mitigation by peatland restoration is suggested, but data from restored forestry‐drained peatlands (FDP) is sparse. Studies using surrogate emission factors from pristine peatlands have indicated a long‐lasting warming effect of restoration of nutrient‐poor FDPs, while restoration‐specific studies are missing.
