Demographic History and Genetic Diversity of Rātā Moehau (Metrosideros bartlettii; Myrtaceae), a Critically Endangered Aotearoa New Zealand Endemic Tree

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Rātā Moehau (Metrosideros bartlettii), a critically endangered tree endemic to Aotearoa New Zealand, is represented by only 14 wild individuals. We assembled its first genome, analysed genetic diversity in wild and cultivated individuals and found long‐term population decline and reduced diversity in cultivated plants—providing key insights to support ...

Effect of PWHT and Electrical Parameters on Austenitic Phase, Sigma Phase and Corrosion in Duplex Steels S32205

Engineering Reports, Volume 8, Issue 4, April 2026.
Welding power and post‐weld heat treatment (PWHT) at 850°C influence phase transformations in S32205 duplex stainless steel, promoting sigma phase formation and reducing corrosion resistance. PWHT at 850°C also replicates HAZ‐like microstructures in base metal, enabling improved characterization of weld joint properties.
