Drying spring accelerates transitions toward pyrogenic vegetation in eastern boreal North America

The ongoing climate change increases vegetation flammability in the boreal forests of eastern North America, leading to more intense and severe wildfires. Using palaeoecological data—including charcoal, pollen, chironomids and testate amoebae—and climate model simulations of vapour pressure deficit (VPD) and available soil water (ASW), we analysed fire dynamics over the past 8000 years in boreal eastern North America. Over the last 4000 years, and particularly in the last 250 years, increasin...

Taxonomic revision of the genus Prasiola Meneghini, 1838 (Prasiolaceae, Trebouxiophyceae) results in the establishment of three new genera

With 35 currently recognised species, Prasiola Meneghini, 1838 is the largest genus of the family Prasiolaceae (Prasiolales, Trebouxiophyceae). However, recent molecular phylogenetic studies have shown that the genus as currently conceived is polyphyletic, due to a separate genus, Prasiococcus Vischer, clearly being nested between the Prasiola clades. Since the clade containing the type species Prasiola crispa (Lightfoot) Kützing has priority, we propose three new taxonomic realignments, base...

Electrophysiological Phenotype-Genotype Study of Sustained Monomorphic Ventricular Tachycardia in Inherited, High Arrhythmic Risk, Left Ventricular Cardiomyopathy

BACKGROUND: Among inherited cardiomyopathies involving the left ventricle, whether dilated or not, certain genotypes carry a well-established arrhythmic risk, notably manifested as sustained monomorphic ventricular tachycardia (SMVT). Nonetheless, the precise localization and electrophysiological profile of this substrate remain undisclosed across different genotypes. METHODS: Patients diagnosed with cardiomyopathy and left ventricle involvement due to high-risk genetic variants and SMVT trea...
