Color polymorphism in Anemone coronaria: Correlations with soil, climate, and flowering phenology

open access: yesAmerican Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Premise Flower color polymorphism (FCP) is thought to be driven by multiple selection agents. Although widely associated with visual attraction of multiple pollinators, FCP is also often correlated with abiotic factors. We explored the links between abiotic conditions, flowering phenology, and FCP in the winter‐flowering geophyte Anemone ...

Selection maintains floral color polymorphism in scarlet paintbrush, Castilleja coccinea, reflecting combined ecological factors

open access: yesAmerican Journal of Botany, Volume 113, Issue 1, January 2026.
Abstract Premise Evolutionary theory predicts polymorphism should be rare; however, intraspecific variation in floral color is common and can be attributed to genetic drift, plasticity, or variable selection. Examining floral color polymorphism both within contact zones and across a species' range can reveal the mechanisms maintaining this variation ...

Habitat Type and Group Identity Influence Activity Budgets in White‐Handed Gibbons (Hylobates lar) in Two Habitat Types in Western Thailand

open access: yesAmerican Journal of Primatology, Volume 88, Issue 1, January 2026.
Seasonal activity budgets for four groups of white‐handed gibbons (Hylobates lar) at Khao Nang Rum Wildlife Research Station, Huai Kha Khaeng Wildlife Sanctuary, Thailand, from March 2012 to May 2013. Groups A and B are located in the evergreen habitat, while groups D and L are located in the savannah habitat.

Comparison of various fertilizer recommendations for forage crops in the Western United States

open access: yesCrop Science, Volume 66, Issue 1, January/February 2026.
Abstract Farmers often use private and public labs, crop advisors, or fertilizer dealers to determine fertilizer needs for crops, with recommendations and resulting costs from these sources having the potential to vary greatly. Twelve on‐farm trials across the state of Utah in alfalfa (Medicago sativa), small grain forage, and silage corn (Zea mays ...

Integrating early spring‐planted barley or oat for Palmer amaranth management in soybean

open access: yesCrop Science, Volume 66, Issue 1, January/February 2026.
Abstract Fall‐planted cover crops (CCs) are widely used for weed suppression, but CC establishment challenges after fall harvest in temperate regions necessitate alternative approaches. The objectives of this study were to evaluate the integrated effect of spring‐planted barley or oat CC and herbicide programs for CC biomass production, Palmer amaranth
