Managing polyploid complexity in grassland restoration: Cytotype differentiation and implications for seed zones

open access: yesJournal of Applied Ecology, Volume 63, Issue 1, January 2026.
Our decision framework enables seed producers and managers to take consistent action on the challenge of polyploid complexes in restoration. Different ploidy levels should not be mixed to avoid fitness losses. Depending on abundance and distribution, either the dominant ploidy level should be prioritised, or multiple ploidy levels need to be managed ...

Bulbil formation in stress: Crucial role of triploid fitness in mixed ploidy dynamics in Costus speciosus

open access: yesPlant Species Biology, Volume 41, Issue 1, January 2026.
Upon prolonged waterlogging, a Costus speciosus plant developed bulbils at stem node. Karyotype analysis, nucleolar staining, and anatomical study revealed its triploid status and developmental aspects. Prevalence of tetraploid, abundance, and unique reproductive fecundity of the triploid, indicates its determinant role in coexistence of the multiple ...

Phylogenomic Barcoding of Soil Seed Bank–Persistent and Wind‐Dispersed Non‐Native Plant Species in South Georgia

open access: yesMolecular Ecology Resources, Volume 26, Issue 1, January 2026.
ABSTRACT Climate change and invasive species are leading drivers of biodiversity loss, with island ecosystems being especially vulnerable. South Georgia, a remote sub‐Antarctic island, is 170 km long with approximately 30,000 ha of vegetated coastal areas, as snow and ice dominate the inland regions.

Recommendations for Human Sperm Morphology Assessment in 2025: An Expert Review From the French BLEFCO Group

open access: yesAndrology, Volume 14, Issue 1, Page 10-24, January 2026.
ABSTRACT Background Numerous publications have questioned the lack of analytical reliability and clinical relevance of sperm morphology assessment for infertility workup and before use of assisted reproductive techniques (ART). There is a huge variability in the performance and interpretation of this test.

Lysine demethylase 4A is a centrosome‐associated protein required for centrosome integrity and genomic stability

open access: yesThe FEBS Journal, Volume 293, Issue 2, Page 396-417, January 2026.
KDM4A, a chromatin eraser, localizes to the centrosomes. Its demethylase activity is essential for maintaining centrosome number and integrity, independent of gene expression changes. Loss of KDM4A leads to centrosome amplification, pseudo‐bipolar spindle formation, and chromosome segregation errors, including micronuclei and chromatin bridges.
