Free-roaming dogs have been present in the Galápagos Islands since the 1830s, but their population significantly increased in the 1900s, posing a threat to wildlife and spreading diseases. Efforts to manage the dog population began in 1981; however, large populations still exist on Isabela and Santa Cruz Islands, with their genetic backgrounds not thoroughly investigated until now. A comprehensive genomic analysis was conducted on 187 modern Galápagos dogs, six historical samples between 1969 and 2003, and data from over 2,000 purebred and village dogs. Findings reveal that contemporary Galápagos dogs are a recent mix of purebred breeds without evidence of a population bottleneck from past culling efforts. Furthermore, historical dogs showed signs of shared ancestry with shepherd dogs. Overall, the study suggests that 1980s culling did not effectively control dog populations and indicates a need for improved population management strategies on the islands to protect endangered species.

Phylogenomic data are enhancing insect phylogenetics, particularly through target enrichment methods. This study introduces an Orthoptera-specific target enrichment (OR-TE) probe set developed from 80 transcriptomes, targeting 1828 loci with diverse evolutionary rates. The probe set was validated by generating phylogenomic data from 36 previously unstudied orthopteran species, capturing an average of 1037 loci and clarifying phylogenetic relationships. Documentation of the probe design and bioinformatics process aims to promote broader adoption of this tool.

Early natural historians—Comte de Buffon, von Humboldt, and De Candolle—established environment and geography as two principal axes determining the distribution of groups of organisms, laying the foundations for biogeography over the subsequent 200 years, yet the relative importance of these two axes remains unresolved. Leveraging phylogenomic and global species distribution data for Mimosoid legumes, a pantropical plant clade of c. 3500 species, we show that the water availability gradient from deserts to rain forests dictates turnover of lineages within continents across the tropics. We demonstrate that 95% of speciation occurs within a precipitation niche, showing profound phylogenetic niche conservatism, and that lineage turnover boundaries coincide with isohyets of precipitation. We reveal similar patterns on different continents, implying that evolution and dispersal follow universal processes. , Water availability dictates patterns of global phylogenetic beta diversity in tropical plants.

Since emerging in Brazil in 1985, wheat blast has spread throughout South America and recently appeared in Bangladesh and Zambia. Here we show that two wheat resistance genes, Rwt3 and Rwt4, acting as host-specificity barriers against non-Triticum blast pathotypes encode a nucleotide-binding leucine-rich repeat immune receptor and a tandem kinase, respectively. Molecular isolation of these genes will enable study of the molecular interaction between pathogen effector and host resistance genes.
