The anthropogenic fingerprint on emerging infectious diseases

Abstract Emerging infectious diseases are a hallmark of the Anthropocene 1,2 . Human-driven ecosystem changes and human–wildlife–livestock contact can drive the emergence of zoonotic and vector-borne diseases 3–5 , but how much these processes shape landscapes of outbreak risk is...

Effects of Water-Saving Technologies on the Establishment and Reproductive Phenology of Five Crop Species Under Rain-Fed Conditions on Floreana Island (Galápagos)

Water scarcity is a major constraint to agricultural production on small oceanic islands, where freshwater availability is naturally limited and production systems depend heavily on rainfall. In the Galapagos Islands, agriculture plays an important role in local food supply and r...

Method Sensitivity in Façade-Based Traffic Noise Exposure and Health-Burden Assessment in Quito

Strategic noise maps represent a valuable tool for the characterisation of urban soundscapes, but their transformation into indicators related to the exposed population and health effects remains a matter of methodology, particularly in the absence of dwelling-level information....

Antitumor-Relevant Evaluation of Liquid and Microencapsulated Lepidium meyenii and Bactris gasipaes Extracts Reveals Species- and Formulation-Dependent Activity

Lepidium meyenii and Bactris gasipaes are traditionally consumed plant foods with documented antioxidant and inflammation-related activities and emerging evidence of cancer-related biological effects. Accordingly, we compared the antitumor-relevant activity of these chemically di...

E2(η6–Be6H6) (E = Si–Pb): Doubly Aromatic Inverse-Sandwich Complexes

Abstract We report E2(η6-Be6H6) (E═Si, Ge, Sn, Pb), a new family of doubly aromatic inverse sandwich clusters in which a tetrel diatomic is sandwiched between a beryllium hydride ring. All four members adopt a singlet D6h global minimum, separated from the nearest competing isome...
