Altered Ocean Temperature Gradients Are Key to Miocene South Asian Monsoon Evolution

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Indian Ocean sea surface temperature (SST) gradients influence South Asian summer monsoon (SASM) strength. Middle Miocene proxy records show reversed Arabian Sea zonal gradients (warmer west than east) and reduced Indian Ocean meridional gradients compared to today—patterns coupled models cannot reproduce, hindering accurate SASM simulation ...

Global Diversification Rates of Ferns Across Spatial and Climatic Gradients

open access: yesAdvanced Science, Volume 13, Issue 3, 14 January 2026.
Diversification rates of fern genera across the phylogeny. Abstract Geographic patterns of diversity in any group of plants are the result of the interplay of environmental conditions and the evolutionary dynamics of the respective plant group. Here, the geographic distribution of current mean diversification rates (MDR) is explored at the genus level ...

A mosaic of colors: The influence of biotic and abiotic factors shaping flower color diversity across a tropical mountain ecosystem

open access: yesAmerican Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Premise Flower color diversity within communities is shaped by biotic and abiotic factors. Pollinators often prefer specific colors, and floral pigments also help protect against abiotic factors such as ultraviolet (UV) radiation, precipitation, and temperature.
