Application of a Presumptive Standards Approach to Evaluate Environmental Flows in a Highly Regulated River Basin

open access: yesRiver Research and Applications, EarlyView.
ABSTRACT The presumptive standards approach to environmental flows offers a method to develop interim guidelines for ecological and social‐cultural flow needs. The approach is based on deriving acceptable percent‐of‐flow limits based on naturalised flows (the absence of depletion or alteration of flow), and it can be an effective precursor to a full ...

Nitrogen Policy for Sustainable Agriculture in the US: Estimating Socially Optimal Application Rates and Economic Impacts

open access: yesSustainable Development, EarlyView.
ABSTRACT Nitrogen (N) application creates negative externalities via nitrate (NO3−) leaching that threatens human health and the emission of nitrous oxide (N2O), a potent greenhouse gas. This study determines socially optimal nitrogen application rates (SONR) for corn and wheat by considering the social costs of both pollutants. The assessment includes

Assessing the accuracy of field‐based versus laboratory methods for determining the age of roe deer

open access: yesWildlife Biology, EarlyView.
Accurate age determination in roe deer Capreolus capreolus is essential for selective harvesting and informed population management, yet field‐based methods widely used by hunters remain imprecise. This study compared field‐based and laboratory age determination methods in 204 harvested roe deer, categorized by sex and habitat type (forest versus open ...

Space and resource use by American crow Corvus brachyrhynchos in an area endemic for chronic wasting disease

open access: yesWildlife Biology, EarlyView.
American crow Corvus brachyrhynchos is a common species throughout North America. Crows play a role in the ecology of multiple diseases and a single laboratory experiment has shown the potential for crows to pass infectious prions, such as those associated with chronic wasting disease (CWD), in their feces after being force‐fed with infected material ...
