Local Trade‐Offs Shape Flower Size Evolution Across Arabidopsis thaliana Distribution
Molecular Ecology, Volume 35, Issue 17, September 2026.ABSTRACT The remarkable variation in floral form and size is thought to have driven the evolutionary radiation of angiosperms and has traditionally been attributed to pollinator‐mediated selection on floral displays, yet emerging evidence indicates that abiotic environmental factors can also generate and filter variation in flower size.

Molecular Ecology, Volume 35, Issue 17, September 2026.ABSTRACT The evolution of genotypic parallelism under shared environmental conditions provides strong evidence for the role of natural selection. However, analyses typically examine genomic signatures of selection long after the putative selection event and only assess the repeatability of responses across spatial population replicates.

Molecular Ecology, Volume 35, Issue 18, September 2026.ABSTRACT Sky island mountain ranges of the American Southwest represent isolated habitat fragments surrounded by arid lowland barriers, making them powerful natural experiments for studying population divergence, demographic history and local adaptation. Here, we use whole‐genome resequencing of the Western Hercules beetle (Dynastes grantii Horn, 1870)

Maximum water stress is decoupled from climate, traits, and growth in a xeric oak
New Phytologist, Volume 251, Issue 5, Page 2392-2406, September 2026.We sampled sites across the geographic distribution of blue oak (Quercus douglasii) in California, USA, which spans a large range of mean annual precipitation. Summary Our ability to explain and predict the spatial patterns of forest mortality remains limited.

Physiologia Plantarum, Volume 178, Issue 5, September/October 2026.ABSTRACT As climate warming and more frequent heatwave events cause increasing damage to native and managed forest trees, there is an urgent need to characterise species thermotolerance thresholds and define their capacity to acclimate to warmer growth conditions.

How Was Democracy Under the Administrative Presidency Supposed to Work?
Public Administration Review, Volume 86, Issue 5, Page 1225-1234, September/October 2026.ABSTRACT Aggressive use of the administrative power of the presidency is a major source of public administrative concern about the health of American democracy. Many of these powers stem from executive branch reorganization in the late 1930s, which was conceived and implemented by founding figures in the modern field.

Restoration Ecology, Volume 34, Issue 7, September 2026.Abstract Introduction Singleleaf pinyon pine (Pinus monophylla) holds both ecological and cultural significance for Indigenous Tribes of the Great Basin, such as the Washoe Tribe of Nevada and California. Recent wildfires on Washoe Tribal lands have resulted in the loss of important pinyon pine groves, prompting collaborative efforts to develop post ...
