Multiple Glacial Refugia and Complex Postglacial Dynamics of Primula sikkimensis (Primuaceae) in the Heterogeneous Qinghai‐Tibet Plateau

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
Primula sikkimensis persisted in distinct glacial refugia within the Hengduan Mountains and eastern Himalayas during the Last Glacial Maximum. Subsequent postglacial range expansions onto the Qinghai–Tibet Plateau were accompanied by secondary contact and interspecific hybridization, collectively enhancing genetic diversity and adaptive capacity. These

Gradual pollen release in a buzz‐pollinated plant: Investigating pollen presentation theory under bee visitation

open access: yesFunctional Ecology, Volume 40, Issue 2, Page 476-485, February 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The rate at which flowers dispense pollen across successive pollinator visits is a key functional trait influencing male reproductive success. Pollen presentation theory (PPT) predicts that when pollinators are abundant and actively groom their bodies to collect pollen,

Decrease of sexual organ reciprocity between heterostylous primrose species, with possible functional and evolutionary implications [PDF]

open access: yes, 2017
Background and Aims Heterostyly is a floral polymorphism that has fascinated evolutionary biologists since Darwin's seminal studies on primroses. The main morphological characteristic of heterostyly is the reciprocal placement of anthers and stigmas in ...

DNA methyltransferase inhibitors in hematological malignancies and solid tumors

open access: yesInternational Journal of Cancer, Volume 158, Issue 2, Page 433-461, 15 January 2026.
Abstract Epigenetic modifications such as DNA methylation play a fundamental role in oncogenesis and the progression of neoplasms neoplasias. DNA methyltransferase inhibitors (DNMTi) constitute a family of therapeutic agents that impede the methylation at the 5‐position on cytosine nucleotides, thereby modulating the epigenetic regulation of tumor ...
