Generalized Metric Formulation of Double Field Theory on Group Manifolds [PDF]

open access: yes, 2015
We rewrite the recently derived cubic action of Double Field Theory on group manifolds [arXiv:1410.6374] in terms of a generalized metric and extrapolate it to all orders in the fields.

Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity

open access: yesConservation Biology, EarlyView.
Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).

How much sampling is enough? Four decades of understorey bird mist‐netting across Amazonia define the minimum effort to uncover species assemblage structure

open access: yesIbis, EarlyView.
Mist‐net sampling comprises a key methodological component of assemblage‐wide avifaunal studies, particularly in the understorey of closed‐canopy tropical forests. To investigate mist‐net bird captures and species assemblage structure, we compiled data from 312 sites across the Pan‐Amazon.

Reunion overseas: introduced wild boars and cultivated orange trees interact in the Brazilian Atlantic forest [PDF]

open access: yes, 2019
Little is known concerning novel interactions between species that typically interact in their native range but, as a consequence of human activity, are also interacting out of their original distribution under new ecological conditions.

Fine‐scale patterns of genetic structure in three species of forest birds reveal dynamic Pleistocene history within an Amazonian interfluve

open access: yesIbis, EarlyView.
Phylogeographical studies of Amazonian birds have revealed large intraspecific diversity, even within recognized areas of endemism. To understand the origin and organization of Amazonian diversity, including the influence of current and historical landscapes, we need to evaluate fine‐scale patterns of genetic diversity in relation to detailed ...

Dose‐Dependent Effect of Plant Volatiles on the Oviposition Preference of the Corn Leafhopper Dalbulus maidis

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Maize (Zea mays L.) is a major annual crop cultivated worldwide. In the Americas, the corn leafhopper Dalbulus maidis (DeLong) (Hemiptera: Cicadellidae) is a key pest of this crop, causing direct damage to plants through phloem feeding and indirect damage by transmitting phytopathogens.

Hoffmann's two‐toed sloth II: Muscle architectural properties in the thoracic limb of Choloepus (Pilosa: Xenarthra)

open access: yesJournal of Anatomy, EarlyView.
Two‐toed sloths use their thoracic limbs for more frequent and greater suspensory support than three‐toed sloths and have muscle architectural properties consistent with stability of the pectoral girdle, enhanced flexor force/torque applied at the shoulder and elbow joints, and grip on the support as indicated by their myology. Abstract Two‐toed sloths
