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

Journal 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 ...

Accumulating time lags across biodiversity levels following land‐use change

Journal of Ecology, Volume 114, Issue 1, January 2026.
Species identity seems central in governing the observed delays at each level of biodiversity, from genetic to functional diversity. In particular, species identity controls the slowest responses at the genetic level, potentially leading to accumulating underestimations of the size and duration of time lags at species, community and functional ...

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

Plant 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 ...

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

The 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.
