A review on true dung beetles' evolutionary and ecological responses to temperature and impacts on ecosystem functions

Ecological Entomology, EarlyView.
True dung beetles are a speciose group of ecosystem engineers that play key roles as detritivores in natural and agricultural landscapes. Scarabaeine beetles show strong thermal plasticity and there is increasing evidence of rapid evolutionary divergence in response to temperature across ecological and evolutionary timescales, with likely consequences ...

A defensive symbiont and a plant virus confer direct and discrete phenotypes to a cereal aphid in a context‐dependent manner

Ecological Entomology, EarlyView.
Different BYDV‐PAV isolates exert contrasting effects on aphid fitness, including reproduction and winged production. Different BYDV‐PAV isolates have contrasting effects on aphid dispersal patterns. Aphid feeding behaviour is modulated by the presence of endosymbionts and plant viruses.

Environmental correlates of spatio‐temporal patterns of colour variation in a bird of prey: The common buzzard (Buteo buteo)

Ibis, EarlyView.
High colour variability in animals has been associated with adaptability to environmental change. Establishing how such variability is distributed in time and space, and identifying environmental correlates, can help understand the processes driving it.

Designing a Morphing Wing for Fixed-Wing UAVs By IJISRT

International Journal of Innovative Science and Research Technology (IJISRT)
This project report details the original conceptualization, design, and analysis of a morphing wing structure for fixed-wing Unmanned Aerial Vehicles (UAVs). Our approach incorporates an octahedron cell structure coupled with the application of shape memory alloys(SMAs) to facilitate controlled wing morphing.

Artists in Nursery Schools: Enabling Free Play and Self‐Expression Through the Arts

International Journal of Art &Design Education, EarlyView.
Abstract The purpose of this research was to analyse the presence of artists in nursery schools by means of two proposals to promote free play and self‐expression for children between one and 3 years‐old and their families. Researchers compiled evidence from the perspective of three atelieristas and other participating adults, through interviews and ...

An Efficient SDOF Sweep Wing Morphing Technology for eVTOL-UAV and Experimental Realization

Drones
The presented study demonstrates that UAVs can be flown with a morphing wing to develop essential aerodynamic efficiency without a tail structure, which decides the operational cost and flight safety.
