Three closely linked X‐chromosomal genes potentially control sex determination in Cannabis sativa

New Phytologist, Volume 251, Issue 1, Page 505-522, July 2026.
Summary Sex determination mechanisms in dioecious plants remain poorly understood yet offer an excellent model system to study genetic changes underlying morphological evolution. We investigated the genetic basis of sex determination in Cannabis sativa, combining quantitative trait locus mapping in a segregating population, comparative transcriptomics ...

Governing Cybersecurity in the Digital Age: Mapping Comprehensive Policy Mixes With the Nodality‐Authority‐Treasure‐Organization Lens

Review of Policy Research, Volume 43, Issue 4, July 2026.
ABSTRACT The accelerated digitalisation of society has amplified cybersecurity threats and revealed their cross‐sectoral nature. Yet, the policy instruments used to address these challenges remain insufficiently examined. This study conducts a scoping review of 980 academic articles (2007–2024) and applies Hood's NATO framework (Nodality, Authority ...

Meiosis and fluorescent banding in Edessa meditabunda and E. rufomarginata (Heteroptera: Pentatomidae: Edessinae)

European Journal of Entomology, 2003
Species of Pentatomidae are cytogenetically characterized by the presence of holokinetic chromosomes, a pre-reductional type of meiosis, and a great constancy not only in chromosome number (2n = 14 in 85% of the 250 species analyzed) but also in the sex ...

Rib Cross‐Sectional Mineralized Area in Early Pleistocene Hominins: Insights From the Homo antecessor and H. erectus s. l. Fossil Record

American Journal of Biological Anthropology, Volume 190, Issue 2, June 2026.
ABSTRACT Objectives Rib cross‐sectional mineralized area provides valuable insights into mechanical loading and bone growth and remodeling. Given the scarcity of Early Pleistocene costal remains in the context of human evolution, we aimed to study the cross‐sectional anatomy of fossil ribs from that period and compare them to a modern human ontogenetic

Integrating Niche Dimensions to Advance the Ecological Study of the Americas' Smallest Cat: The Guigna in Argentine Patagonia

Ecology and Evolution, Volume 16, Issue 6, June 2026.
We present our findings from the first multi‐annual survey of guigna in Argentine Patagonia. We found that habitat use for guignas was negatively affected by the presence of co‐predators and open vegetation; conversely, it was positively affected by the occurrence of thick forests and the presence of potential prey.

Complex History of Organellar Introgression in Nothofagus Trees: Chloroplast and Mitochondrial Capture Facilitated by Natural Selection

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Field photograph of an ancient Nothofagus tree covered with epiphytic lichens in the Patagonian temperate rainforest. This genus serves as a key model for investigating organellar introgression and evolutionary genomics in South America. ABSTRACT Hybridization is widespread across diverse groups of organisms, and in some cases, organellar genomes of ...
