PLANTS, PEOPLE, PLANET, EarlyView.Agricultural production systems in the global North combine monocultures of specialised varieties and breeds with external interventions and inputs. Increasing the diversity of varieties, breeds and species may increase the system's resilience to external pressures through beneficial interactions.

Export and benefits of hedging in emerging economies [PDF]
We study the impact of exchange rate risk upon export production within an emerging economy lacking in currency forward markets. However there exists a financial asset whose price is correlated with the relevant foreign currency.

Pest Management Science, EarlyView.Entomopathogenic nematodes provide reliable biological control of vine weevil larvae, reducing populations by 63% on average. All five tested species are effective, with temperature (18–30 °C) being the strongest predictor of success. Abstract BACKGROUND Vine weevil (Otiorhynchus sulcatus) is a globally important pest of soft fruit and ornamental crops

Spatial Price Discovery, Dynamics, and Leadership in Evolving Distiller’s Grain Markets [PDF]
Recent dramatic growth in corn-based bio-refining has generated considerable growth in the by-product of this process, distiller’s grains. Distiller’s grains are rapidly becoming important livestock feed ingredient sources.

Software to Support Remote Sensing of River Discharge Based on Critical Flow Theory
River Research and Applications, EarlyView.ABSTRACT Water resource management requires accurate observations of streamflow but standard field methods for measuring river discharge (Q$$ Q $$) can be costly and hazardous for equipment and personnel. Remote sensing has become a viable alternative, but many image‐based techniques require field data for calibration, and depth and velocity can seldom

SPATIAL ANALYSIS OF FEEDER CATTLE HEDGING RISK [PDF]
Optimal hedge ratios are estimated for various weights of feeder cattle in four cash markets based on CME data from 1992 to 1999. Three-month uniform hedges are simulated for every weight, contract, and cash market combination.

Remote Sensing in Ecology and Conservation, EarlyView.We combined arboreal camera trapping and non‐invasive genetic tagging to estimate group size in the critically endangered northern muriqui (Brachyteles hypoxanthus) in Brazil's Atlantic Forest. Both methods provided complementary insights into group size and demographic structure, while differing in their cost‐effectiveness and sampling constraints ...
