Island radiations, such as those of the Australo-Pacific, offer unique insight into diversification, extinction, and early speciation processes. Yet, their speciation and colonization histories are often obscured by conflicting genomic signals from incomplete lineage sorting (ILS) or hybridization. Here, we integrated mitogenomes and genome-wide SNPs to unravel the evolutionary history of one of the world's most geographically widespread island radiations.

The diversification of hummingbirds (Trochilidae) has shaped the pollination strategies and floral trait evolution in at least 68 families of flowering plants in the Western Hemisphere. The trumpet creeper (Bignoniaceae) is the quintessential example of ornithophily in eastern North America. The mutualistic relationship between this orange-flowered liana and the ruby-throated hummingbird () was illustrated as early as 1731.

Article Synopsis
  • Relationships among avian lineages remain unresolved due to factors like species diversity, phylogenetic methods, and selection of genomic regions.
  • An analysis of 363 bird species' genomes reveals a well-supported evolutionary tree but highlights significant discrepancies among certain groups.
  • Findings suggest that after the Cretaceous-Palaeogene extinction, birds experienced increased population size and diversification, which offers a new foundational understanding for future research in avian evolution.

The core breeding range of Swainson's warbler () overlaps a zone of exceptionally high tornado frequency in southeastern North America. The importance of tornadoes in creating breeding habitat for this globally rare warbler and other disturbance-dependent species has been largely overlooked. This paper estimates tornado frequency (1950-2021) and forest disturbance in the 240 counties and parishes in which breeding was documented from 1988 to 2014.

During the COVID-19 pandemic, wastewater surveillance was widely used to monitor temporal and geographical infection trends. Using this as a foundation, a statewide program for routine wastewater monitoring of gastrointestinal pathogens was established in Oklahoma. The results from 18 months of surveillance showed that wastewater concentrations of , and norovirus exhibit similar seasonal patterns to those observed in reported human cases (F = 4-29, < 0.
