This month sees two chapters in Advances in Ecological Research ( produced by the PREDICTS team and collaborators! Chapter four: “Challenges With Inferring How Land-Use Affects Terrestrial Biodiversity: Study Design, Time, Space and Synthesis”, syntheses the advantages and challenges that different study designs face, including spatial comparisons (e.g. those collated in PREDICTS v1) and temporal designs (e.g. those used in PREDICTS v2). Chapter five: “Modelling and Projecting the Response of Local Terrestrial Biodiversity Worldwide to Land Use and Related Pressures: The PREDICTS Project”, discuss the motivations behind the PREDICTS project, its protocols, and key decisions that helped to reach its objectives.
