The association between parent–child and peer relationship quality in adolescence and intimate partner relationship quality in young adulthood: A two‐cohort longitudinal investigation

open access: yesJournal of Research on Adolescence, Volume 36, Issue 2, June 2026.
Abstract Adolescent experiences in close relationships play a seminal role in social–emotional development across the lifespan. Here, we examine the unique and combined effects of parent–child and peer relationship quality in adolescence (age 11–13 years) in shaping intimate partner relationship quality in young adulthood (age 19–28 years). Prospective

Somatic genome‐doubling is the most parsimonious route to allopolyploidy

open access: yesNew Phytologist, Volume 250, Issue 5, Page 2845-2851, June 2026.
Summary The origin of a polyploid can hinge on a single errant cell division, a mistake in the cell cycle that leads to genome‐doubling and re‐writes the rules of chromosome pairing and segregation. In plants, the evolutionary significance of these errors is magnified by lack of an early sequestered germline, meaning somatic mutations can be heritable.

Phylogenetic Diversity and Community Assembly of Vascular Plants Along Environmental Gradients in the Western Pamir–Alay: A Case Study From Surkhandarya Province, Southern Uzbekistan

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Using extensive field, herbarium, and database records, we examine patterns of species richness, phylogenetic diversity, and community assembly along elevational and climatic gradients in an understudied region of Central Asia. ABSTRACT Biodiversity plays a fundamental role in ecosystem structure, function, and stability, but its response to ...

Extensive Pollen Flow and Historical Population Expansions Shaped the Phylogeographic Pattern of Choerospondias axillaris: Evidence From Chloroplast DNA and ITS Sequences

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
MaxEnt‐based predictions reveal dramatic range dynamics of Choerospondias axillaris during Quaternary climate cycles, including northward expansion during the last interglacial, southward contraction into fragmented refugia during the last glacial maximum, and subsequent northward recolonization since the post‐glacial period.
