A full integrated system for agroclimatic and pest monitoring at farm and landscape scales in Campania Region

open access: yesIOP Conference Series: Earth and Environmental Science, 2019
Abstract The current agrometereological monitoring of the Campania Region is both inadequate for its users and insufficient to support the simulation of pest risk models. This work describes a cyber-physical system which has been designed to overcome these limitations, with the objective of (i) automate all the tasks involved in climatic

Is ground cover vegetation an effective biological control enhancement strategy against olive pests? [PDF]

open access: yesPLoS ONE, 2015
Ground cover vegetation is often added or allowed to generate to promote conservation biological control, especially in perennial crops. Nevertheless, there is inconsistent evidence of its effectiveness, with studies reporting positive, nil or negative ...

Causal analysis of trade loss from pathogens: A global study of foot and mouth disease impacts on meat exports

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract Our general interest is in global trade loss from livestock pathogens, specifically exports. We adopt a causal inference approach that considers animal disease outbreaks over time as non‐staggered binary treatments with the potential for switching in (infection) and out of treatment (recovery) within the sample period. The outcome evolution of

The role of venture‐financed startups in innovation for US agriculture

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract To evaluate the role played by startup companies in the innovation ecosystem of US agriculture, we compile a unique dataset of 6024 new entrants founded 1987–2019 that details their financing lifecycles, annual economic performance, and patenting activities.

High‐elevation endemic plants predicted to lose habitat from changing climate in Washington State

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise High‐elevation plants face unique challenges from potential climate change impacts that will likely require upslope migration into increasingly smaller suitable habitat. This situation is particularly acute for endemic species that by definition occupy small geographic ranges.

Heat Transfer Fluids as Co‐Diluents in Localized High‐Concentration Electrolytes for High‐Rate Lithium Metal Batteries With Enhanced Safety

open access: yesAngewandte Chemie International Edition, EarlyView.
Two fluorinated ethers, commonly used as heat‐transfer fluids, are explored as co‐diluents in localized high‐concentration electrolytes (LHCEs) for lithium metal‐based batteries. The best‐performing ternary diluent blend boosts ion mobility and cuts overvoltages, thereby improving Coulombic efficiency and cycle life at ≥1 mA cm−2 in zero‐excess pouch ...
