Molecular Ecology, Volume 34, Issue 22, November 2025.ABSTRACT Habitat loss and fragmentation (HLF) are among the major drivers of bee decline, yet closely related species often show contrasting responses depending on their ecological and demographic traits. The Brazilian Cerrado biodiversity hotspot experiences among the world's highest rates of HLF.

Point Mutations in Centromeric Histone Induce Post-zygotic Incompatibility and Uniparental Inheritance. [PDF]
, 2015 The centromeric histone 3 variant (CENH3, aka CENP-A) is essential for the segregation of sister chromatids during mitosis and meiosis. To better define CENH3 functional constraints, we complemented a null allele in Arabidopsis with a variety of mutant ...

New Phytologist, Volume 248, Issue 3, Page 1368-1384, November 2025.Summary Algal blooms and their demise by viruses drive global‐scale ecological processes in the ocean. These blooms form the foundation of marine food webs, regulate microbial communities, and shape biogeochemical cycles. Although algal populations are constantly infected by viruses, resistant subpopulations frequently emerge after the infection.

American Journal of Primatology, Volume 87, Issue 5, May 2025.Mitochondrial DNA analysis suggests that founder‐event speciation played a key role in the divergence between cis‐Andean and trans‐Andean clades, as well as in the diversification of cis‐Andean lineages. Ancestral range reconstruction using mitochondrial genomes indicates that the most recent common ancestor of Alouatta had a widespread distribution ...

Cellular origins of mucinous ovarian carcinoma
The Journal of Pathology, Volume 266, Issue 1, Page 9-25, May 2025.Abstract Mucinous ovarian carcinoma (MOC) is a rare histotype of epithelial ovarian cancer. Its origins are obscure: while many mucinous tumours in the ovary are metastases from the gastrointestinal tract, MOC can occur as an ovarian primary; however, the cell of origin is not well established.
