Research on Three‐Dimensional Autonomous Obstacle Avoidance Path Planning Methods for UAVs

open access: yesTransactions on Emerging Telecommunications Technologies, Volume 37, Issue 2, February 2026.
This study presents a three‐dimensional autonomous obstacle‐avoidance path planning method for unmanned aerial vehicles (UAVs) based on a deep reinforcement learning (DRL)‐enhanced Mayfly Algorithm. The traditional Mayfly Algorithm suffers from issues such as random initial population generation and slow convergence.

Unlocking landscape transient dynamics: Integrating traditional ecological knowledge for enhanced analysis of land‐use changes and forest expansion in a Mediterranean ecosystem

open access: yesPeople and Nature, Volume 8, Issue 2, Page 283-300, February 2026.
Abstract The Industrial Revolution triggered rural abandonment in Europe and had a profound impact on land configuration and ecosystem dynamics, mainly the growth of forests at the expense of open agricultural habitats. However, rural abandonment has been asynchronous in space and time, depending on regional socio‐economic dynamics.

The Weak Worker Hypothesis: a new framework for understanding division of labour in social insects

open access: yesBiological Reviews, Volume 101, Issue 1, Page 5-13, February 2026.
ABSTRACT In social species, group functions often benefit from variation among individual group members. Many highly integrated social insect colonies rely on division of labour among colony members and emergent properties of their collective behaviour and physiology. Response threshold models are a prominent proximate explanation of division of labour,
