Emergence, spread, and impact of high‐pathogenicity avian influenza H5 in wild birds and mammals of South America and Antarctica

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract The currently circulating high‐pathogenicity avian influenza (HPAI) virus of the subtype H5 causes variable illness and death in wild and domestic birds and mammals, as well as in humans. This virus evolved from the Goose/Guangdong lineage of the HPAI H5 virus, which emerged in commercial poultry in China in 1996, spilled over into wild birds,

Tooth–bone attachment tissue is produced by cells with a mixture of odontoblastic and osteoblastic features in reptiles

Journal of Anatomy, Volume 248, Issue 2, Page 251-268, February 2026.
Tooth attachment in vertebrates ranges from ligament‐based anchorage in mammals to direct fusion in many reptiles. In the veiled chameleon, we identified a transient cell population—termed ankyloblasts—at the tooth‐bone interface. These cells exhibit both odontoblast‐ and osteoblast‐like features.

Patterns of Interploidy Admixture in Polyploid Complexes: Insights From Thymus Sect. Mastichina (Lamiaceae)

Molecular Ecology, Volume 35, Issue 3, February 2026.
ABSTRACT Understanding gene flow between ploidy levels in polyploid complexes is essential for species delimitation and conservation. This study explores evolutionary dynamics in the polyploid complex Thymus sect. Mastichina (Lamiaceae), comprising three taxa: T. mastichina subsp. mastichina, T. mastichina subsp.

The frequency and importance of polyploidy in tropical rainforest tree radiations

New Phytologist, Volume 249, Issue 4, Page 2103-2114, February 2026.
Summary The presence of more than two copies of the genome in an organism, termed ‘polyploidy’, is a crucial force in plant evolution, generating genetic, phenotypic and ecological diversity. [Correction added on 22 January 2026, after first online publication: the preceding sentence has been corrected.] The Amazonian tree flora is the most species ...
