The missing woodland story: Implications of 1700 years of stand‐scale change on ‘naturalness’ and managing remnant broadleaved woodlands

People and Nature, Volume 8, Issue 6, Page 1572-1587, June 2026.
Abstract Longer‐term perspectives—equivalent to the lifespans of long‐lived trees—are required to fully inform perceptions of ‘naturalness’ used in woodland conservation and management. Stand‐scale dynamics of an old growth temperate woodland are reconstructed using palaeoecological data.

Protein Tyrosine Phosphatase 1B‐Mediated Granulosa Cell Insulin Resistance Links Metabolic Stress to Aging‐Relevant Ovarian Dysfunction and Is Reversed by Gengnianchun

Aging Cell, Volume 25, Issue 6, June 2026.
Metabolic stress induces insulin resistance and upregulates PTP1B in granulosa cells, leading to aging‐relevant ovarian dysfunction. Gengnianchun (GNC) suppresses PTP1B, restores IRS1–AKT2–GLUT4 signaling, and preserves follicles, highlighting PTP1B as a therapeutic target for ovarian dysfunction in metabolically vulnerable states.

POLLEN DIMORPHISM IN THE RUBIACEAE [PDF]

Evolution, 1956
The striking dimorphism of pollen and stigmata fonnd in the majority of the species of the tribe Staticeae in the Plumbaginaceae was discovered by McCleod (1887). This dimorphism and derived monomorphic conditions have been extensively investigated with results that have been found extremely helpful in the elucidation of genetical, genecological ...

Beyond Extrafloral Nectaries: Plant Traits as Drivers of Spider Occurrence in the Cerrado

Austral Ecology, Volume 51, Issue 6, June 2026.
ABSTRACT Patterns of predator occurrence arise from a mosaic of plant‐derived cues, yet most studies address these traits in isolation. Although extrafloral nectaries have received considerable attention, we lack a comprehensive view of how multiple plant traits jointly affect the diversity and abundance of spiders.
