Bioinspired Adaptive Leg‐Claw Enables Robust Perching and Grasping for UAVs
Advanced Science, EarlyView.Inspired by owl limb morphology and bat roosting behavior, this study presents a bioinspired adaptive leg‐claw mechanism that enables UAVs to perform robust and versatile perching and grasping. The design integrates a four‐link tibial structure, tension‐driven deformable feet, and active control, enabling stable perching on various branches and ...

Seasonal variation in the diurnal periodicity of activity of the perch, Perca fluviatilis L. [Translation from: Kalamies 1973(3) 3.] [PDF]
, 1976 The most common catch of the amateur angler is the perch and it is the diurnal periodicity of activity (& catchability) which is examined in this study based on earlier articles and manuscripts by the authors.

Activism as a long durée journey: Teachers against the Chilean neoliberal education model
British Educational Research Journal, EarlyView.Abstract In this paper, I use the idea of purposes of education, particularly subjectification, and the concept of love to explore long‐term teacher activism in Chile. ‘Long‐term activism’ is used to describe an ongoing struggle rather than activism confined to specific moments.

Life-history variation and age at maturity in Eurasian Perch (Perca fluviatilis L.) [PDF]
, 2003 This thesis deals with life-history variation in perch, with special focus on age at maturity. We conducted field studies to uncover the variation within short geographic distances and a literature review to study variation on a large geographic scale in

Classifying avian drinking behaviour: ecological insights and implications in a changing world
Biological Reviews, EarlyView.ABSTRACT Water is a fundamental currency of life, and its availability significantly influences animal behaviour, physiology and distributions. However, our knowledge around the dependence on water for drinking and the direct and indirect mechanisms driving related behaviours remains partial in the context of changing climates. Here, we review patterns
