Climate‐change‐driven shifts in C3 and C4 grass distributions and leaf traits could lead to changes in community‐level flammability

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Climate change poses challenges to grasslands, including those of the North American Great Plains Region, where shifts in species distributions and fire dynamics are expected. Our present analysis focuses on remaining grasslands within this largely developed and agricultural region. The differential responses of C4 and C3 grass species

Production and nutritional composition of two annual ryegrass cultivars (Diploid and Tetraploid) [PDF]

open access: yes, 2019
The feed cost represents the major cost in milk production. Direct grazing and forage produced on the dairy farm could allow the farmer to a better feed production cost control. Ryegrass have been extensively used for grazing and forage production.

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

open access: yesAmerican Journal of Botany, EarlyView.
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 ...

Estimation of the environment as background for selection on adaptivity in white lupine breeding

open access: yesJournal of BioScience and Biotechnology, 2017
A representative evaluation of the breeding value of genotypes in the development of varieties with general and specific adaptability is possible using special features of nature background, which often do not coincide in informativity regarding the ...

Performance of Indigenous and Introduced Slender Wheatgrass in Alaska, and Presumed Evidence of Ecotypic Evolution [PDF]

open access: yes, 1991
Objectives of this study were to evaluate forage and seed production, winter hardiness, and stand longevity of several collections of native Alaskan slender wheatgrass (Agropyron trachycaulum (Link) Malte), and to compare their performance with ...

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

open access: yesAmerican Journal of Botany, EarlyView.
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 ...
