Accounting for animal health in efficiency analysis: An application to Swedish dairy farms
American Journal of Agricultural Economics, EarlyView.Abstract Poor animal health is a central concern in modern livestock production. Despite the necessity to incorporate animal health in efficiency analysis, the theoretical and empirical developments are limited on this subject. This article appropriately characterizes the axiomatic properties of animal health within a production framework.

American Journal of Agricultural Economics, EarlyView.Abstract Preserving ecosystem services, along with economic and environmental benefits, will require future landscape policies to identify and incorporate relevant landscape features. In this paper, we investigate the causal effect of agricultural landscape simplification on drought‐related grassland damages.

Additional Evidence on the Homogeneity of the Value of Government Grazing Leases and Changing Attributes for Ranch Values [PDF]
Using Wyoming ranch sales from 1979-1983 and 1989-1993, this study investigates how ranch value determining attributes may have changed over this period. The 1979-1983 period is one of political stability and rising prices.

Success of coastal sage scrub restoration is influenced by local adaptations of shrub species
American Journal of Botany, EarlyView.Abstract Premise Restoring plant communities is increasingly challenging with climate change. While practitioners have traditionally used local seed sources, many are recommending assisted migration, possibly from more extreme environments such as inland rather than coastal environments, for restoration.

Hierarchical Membrane for Photoelectrostatically Gated Monovalent‐Divalent Ion Separation
Angewandte Chemie International Edition, EarlyView.We report a hierarchical poly(ionic liquid)–carbon nitride membrane supported on anodic alumina for efficient monovalent/divalent ion separation. Confined nanochannels and tailored interfacial ion interactions enable exceptional K+/Mg2+ ( > 500) and Li+/Mg2+ ( > 200) selectivities, offering a promising strategy for advanced aqueous ion separations ...

Cow and Calf Performance as Affected by Grazing Management [PDF]
, 2004 Different grazing treatments cause changes in the quantity of plant growth and the quality of herbage; this study compares cow and calf accumulated weight gain, rate of weight gain per acre, and rate of weight gain per day on various pasture-forage types
