Arctic Bird Migration Monitoring Protocol [PDF]
, 2003 The purpose of this resource is to observe when selected bird species first arrive at your study site, and to count the numbers until few or none of these birds are seen.

(Micro)evolutionary changes and the evolutionary potential of bird migration
, 2018 Seasonal migration is the yearly long-distance movement of individuals between their breeding and wintering grounds. Individuals from nearly every animal group exhibit this behavior, but probably the most iconic migration is carried out by birds, from ...

Survival rates of captive-bred Asian Houbara Chlamydotis macqueenii in a hunted migratory population [PDF]
, 2016 Asian Houbara Chlamydotis macqueenii numbers are declining owing to unsustainable levels of hunting and poaching, with the main conservation response being population reinforcement through the release of captive-bred birds.

Tunable Switching Mechanisms in HfZrO2‐Based Tunnel Junctions for High‐Performance Synaptic Arrays
Advanced Science, EarlyView.This work demonstrates hybrid switching in engineered HZO‐based FTJs, enabled by controlled interlayer design and oxygen scavenging dynamics. The combined switching mechanism produces robust multilevel conductance states in large crossbar arrays, offering a materials‐driven pathway toward scalable in‐memory computing with enhanced tunability and ...

Boosting Photo‐Pyroelectric Effect via Tunable Polarization and Interfacial Defect Engineering
Advanced Science, EarlyView.This study reports Ba(Ti0.85Zr0.15)O3 nanocatalysts with enhanced polarization and oxygen‐vacancy‐rich interfaces for efficient NIR‐II photo‐pyroelectric therapy. Zr doping boosts the pyroelectric coefficient and accelerates polarization switching, while oxygen vacancies improve photothermal conversion and surface reactivity.

Dual‐Strategy Design of Heterojunction‐Enhanced Piezoelectric Hydrogels for Periodontitis Treatment
Advanced Science, EarlyView.This study developed a piezoelectric hydrogel integrating heterojunction enhancement and dual‐salt synergy, combining robust electrical performance with mechanical stability and bioactivity to better match the periodontal microenvironment. Under ultrasound activation, the hydrogel markedly promotes macrophage M2 polarization, thereby reducing the ...
