Evidence of Intraspecific Adaptive Variation in the American Pika (Ochotona princeps) on a Continental Scale Using a Target Enrichment and Mitochondrial Genome Skimming Approach

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Montane landscapes present an array of abiotic challenges that drive adaptive evolution amongst organisms. These adaptations can promote habitat specialisation, which may heighten the risk of extirpation from environmental change. For example, higher metabolic rates in an endothermic species may contribute to heightened cold tolerance, whilst ...

Eco‐evolutionary factors contribute to chemodiversity in aboveground and belowground cucurbit herbivore‐induced plant volatiles

open access: yesPlant Biology, Volume 27, Issue 5, Page 847-860, August 2025.
Herbivore‐induced plant volatiles differ between aboveground leaves and belowground roots both within and among plant species in the Cucurbitaceae, and these differences are correlated with plant domestication and herbivore coexistence history, but not phylogenetic relatedness. Abstract When attacked by insect herbivores, plants emit blends of chemical

Chemical, morphological, and genetic characterization of the floral scent and scent‐releasing structures of Gynandropsis gynandra (Cleomaceae, Brassicales)

open access: yesPlant Biology, Volume 27, Issue 5, Page 710-724, August 2025.
The flowers of African and Asian Gynandropsis gynandra accessions differ in fragrance and epidermal cell morphology (i.e., papillae). Abstract Flowering plants showcase a remarkable diversity in floral fragrances, colours, and structures, which function harmoniously as signals to attract and guide pollinators. Like visual signals, the scents emitted by
