Pollination and plant reproduction in the Cerrado, the world's most biodiverse savanna
ABSTRACT The Brazilian Cerrado is a continental‐wide biodiversity hotspot and the most species‐rich savanna ecosystem in the world. The main aspect characterising this biodiversity is that the landscape is arranged as an intricate mosaic of different plant formations, including grasslands, savannas, and forests, each harbouring distinct but ...

Improvements to context based self-supervised learning
We develop a set of methods to improve on the results of self-supervised learning using context. We start with a baseline of patch based arrangement context learning and go from there.

ABSTRACT The ability of individuals to cope with their environment, and therefore the likelihood that they survive and pass on their genes (i.e. fitness), is largely determined by physiological state. Tracking physiological state in wild animals, however, is challenging.

Stable isotope data indicate origins of mislabelled historical bird specimens
Natural history specimens provide valuable insights across diverse research fields, but those needing more accurate metadata have limited scientific value. We applied stable isotope analysis to investigate the origin of 19th century Atlantic Forest bird specimens attributed to the northeastern Brazilian state of Pernambuco, which are the only records ...

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.

Drought stress leads to reduced nectar secretion and alters nectar composition of day‐ and night‐flowering Nicotiana species, which may impair plant–pollinator interactions. Abstract The frequencies of droughts worldwide will increase in the future due to climate changes. Nectar composition of plant species varies in relation to pollinator and can also

Periodic and Chaotic Flapping of Insectile Wings
Insects use flight muscles attached at the base of the wings to produce impressive wing flapping frequencies. The maximum power output of these flight muscles is insufficient to maintain such wing oscillations unless there is good elastic storage of ...

Understorey bird responses to the abandonment of artisanal gold mining in Guyana
Whilst many forest‐dependent birds will avoid the exposed mine centre, diversity at the immediate edge has the potential to recover, particularly in smaller and older mines. As we have found that natural vegetation recovery occurs at the mine edges and not within the centre, targeted restoration efforts might focus on mine edges to enhance recovery ...

ABSTRACT Introduction Depressive symptoms remain inadequately addressed and undertreated in people who receive life‐prolonging dialysis treatment. Cognitive behavioural therapy (CBT) has been shown to be effective for treating depression; however, we lack an understanding of how and under what circumstances people with depressive symptoms receiving ...
