Biofuels, Bioproducts and Biorefining, EarlyView.Abstract The long‐term viability of Jatropha curcas as a biodiesel feedstock has been widely debated. Many early initiatives failed to deliver consistent economic returns despite promising environmental attributes. This study re‐evaluated J. curcas‐based systems within an integrated environmental–economic framework, focusing on their potential role in ...

Factors that Determine Aflatoxin Infestation in Ghana: Application of Cragg's Double Hurdle Model
Sustainable Futures, 2020 In our application of Cragg's (double hurdle) model, we explicitly address functional form misspecification by first using nonparametric regression to identify the functional relationship between aflatoxin infestation and a vector of agronomic and ...

Spatial metrics in fire ecology: seeking consistency amidst complexity
Biological Reviews, EarlyView.ABSTRACT Technological advances, including remote sensing, have led to a proliferation of metrics used in ecological studies to examine spatial patterns of fire regimes and their ecological effects. Researchers can use many different metrics to analyse spatial variation in both fire events and resulting fire regimes, including fire size, shape ...

Classifying avian drinking behaviour: ecological insights and implications in a changing world
Biological Reviews, EarlyView.ABSTRACT Water is a fundamental currency of life, and its availability significantly influences animal behaviour, physiology and distributions. However, our knowledge around the dependence on water for drinking and the direct and indirect mechanisms driving related behaviours remains partial in the context of changing climates. Here, we review patterns
