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

Ibis, 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.

Boniteza's Arts Chair, Pedagogical Curatorial Practices with Contemporary Artists as Arts‐Based Educational Research

International Journal of Art &Design Education, EarlyView.
Abstract This article puts forward a new methodology in artistic education. It is based on scientific utopia as it aims for the implementation in schools of the cátedras de la Boniteza (the Boniteza's Art Chair), where an inhabiting artist changes the institution from within through the development of quality art projects.

Fit for purpose? Analysis of the relationship between skull, beak shape and feeding ecology in Psittaciformes

Journal of Anatomy, EarlyView.
Psittaciformes exhibit high levels of morphological diversity, particularly in skull and beak structure, previously linked to diet and body size. Although there were some levels of significance between diet and beak shape, body mass was a much stronger co‐variate. Diet is not determining beak shape within the clade.

Citizen‐science data provides new insight into annual and seasonal variation in migration patterns

Ecosphere, 2015
Current rates of global environmental and climate change pose potential challenges for migratory species that must cope with or adapt to new conditions and different rates of change across broad spatial scales throughout their annual life cycle.

Welfare and Felt Duration

Noûs, EarlyView.
ABSTRACT How should we understand the duration of a pleasant or unpleasant sensation, insofar as its duration modulates how good or bad the experience is overall? Given that we seem able to distinguish between subjective and objective duration and that how well or badly someone's life goes is naturally thought of as something to be assessed from her ...

Conservation of animal–plant mutualistic networks is essential to prevent functional extinction of the narrow endemic morning glory Ipomoea cavalcantei in Amazon canga ecosystems

Frontiers in Ecology and Evolution
Current studies of animal–plant mutualistic interaction networks and species climate change resilience call for redesigning biodiversity conservation management toward preventing species coextinction cascades and using interspecific hybridization as a ...

The power of ionic movements in plants

New Phytologist, EarlyView.
Summary The movement of ion‐driven electrogenic events known as plant action potentials in the Venus flytrap Dionaea muscipula has first been recognized in Darwin's time. Besides electrophysiological techniques making use of current‐ and voltage‐recording electrodes, today an ever‐growing spectrum of tools has become available, that report online ...
