Background and Aims: Climate gradients influence seed morphology, emergence, and early life history traits with cumulative impacts to individual fitness. For ex situ seed collections, which represent an invaluable repository of potential trait information for species management and conservation, climate data can guide preservation of adaptive variation and inform deployment strategies for restoration. Here we […]
Frequent seasonal reassortment between high and low path viruses drives the diversification of influenza A/H5N1
Since 2021, highly pathogenic (HPAI) H5N1 viruses have spread across the Americas, diversifying via reassortment into new genotypes that have spilled into humans and livestock, raising fears of a new influenza pandemic. Pandemic lineages are typically associated with reassortment, but we currently have limited understanding of where and when reassortment is expected to occur, which […]
Energetic misfires: Hybridization drives transgressive expression in metabolic pathways in thermally divergent Icelandic stickleback
Climate change is causing rapid changes to freshwater environments, driving selection for phenotypes that can cope with altered thermal conditions, while also changing developmental environments. This may promote local adaptation, migration to new habitats, and/or phenotypic plasticity. Climate change may also increase hybridization rates between locally adapted phenotypes, as populations migrate and spatially mix in […]
