Understanding fire conflict through stakeholder mapping in Madagascar's grassy biomes

People and Nature, EarlyView.
Abstract Fire management in biodiverse regions where rural communities depend on traditional fire‐use practices presents a complex global challenge, particularly in Madagascar where fire is considered a threat to forests yet is essential for maintaining grassland ecosystem health and rural livelihoods.

The importance of integrating herbarium records into conservation plans: a case study on Honduran ferns and lycophytes

PLANTS, PEOPLE, PLANET, EarlyView.
Herbarium collections are powerful, yet underutilized, tools for global biodiversity conservation and protected area management. By integrating digitized herbarium records with existing biodiversity data, previously unknown plant species were uncovered, exposing critical gaps in conservation knowledge.

A manifesto for plant science education

PLANTS, PEOPLE, PLANET, EarlyView.
Plants provide oxygen, food, shelter, medicines and environmental services, without which human society could not exist. Tackling pressing and global challenges requires well‐trained plant scientists and plant‐aware individuals. This manifesto provides a practical evidence‐based vision to strengthen plant science education, focussed on five strategic ...

Injection Locking of Gigahertz‐Frequency Surface Acoustic Wave Phononic Crystal Oscillator

physica status solidi (a), EarlyView.
The compact surface‐acoustic‐wave phononic‐crystal oscillator is stabilized by injection locking it to an ultra‐stable reference. The injection locking suppresses the phase noise by 40 dB at low offset frequency region and reduces long‐term frequency drift from hundreds of hertz to 0.35 Hz, advancing portable, high‐performance timing and signal ...
