Ecology and Evolution, Volume 16, Issue 4, April 2026.The manuscript addresses the sex determination of spiderlings of the wolf spider Allocosa marindia using flow cytometry. Spiders are born with a defined sex, but it is not possible to determine their sex phenotypically until the adult or near‐adult stage. Sex identification at early stages of development is of great interest for studies in evolutionary

Applications in Plant Sciences, Volume 13, Issue 3, May-June 2025.Abstract Premise Pectocarya recurvata (Boraginaceae, subfamily Cynoglossoideae), a species native to the Sonoran Desert (North America), has served as a model system for a suite of ecological and evolutionary studies. However, no reference genomes are currently available in Cynoglossoideae. A high‐quality reference genome for P.

Sex‐Specific Variation in Foraging Behavior is Related to Telomere Length in a Long‐Lived Seabird
Ecology and Evolution, Volume 14, Issue 12, December 2024.Foraging during breeding is energetically demanding, intimately linked to breeding investment, and possibly constrained by individual condition. Telomere length, the protective nucleoproteins located at the ends of the chromosomes, is considered a trait reflecting somatic maintenance and individual quality. We found that brown booby females with longer

Ecology and Evolution, Volume 14, Issue 9, September 2024.We dissect the co‐evolution and genetic architecture of lateral line scale counts and vertebrae numbers in Neotropical Heroine cichlids. Our phylogenetic comparative analyses recovered a positive correlation between these two traits. Furthermore, our qualitative traits locus (QTL) analyses identified significant genomic co‐localized associations for ...
