Alpine flora of Kashmir Himalaya: floristic assessment, life history traits and threat status

open access: yesNordic Journal of Botany, Volume 2026, Issue 7, July 2026.
Alpine ecosystems in the Himalaya are considered to be at a higher risk to anthropogenic global change drivers. The Kashmir Himalaya, located in the north‐western side of the Himalayan biodiversity hotspot, harbors a diverse alpine flora, which remains systematically little investigated.

Generalist passerine birds perform a functional role as pollinators in temperate Europe

open access: yesJournal of Ecology, Volume 114, Issue 7, July 2026.
Nectar‐feeding birds are effective pollinators. In temperate Europe, songbirds visit flowers but lack specialist traits, so functional pollination has been discounted. We use observations, pollen identification and experiments to demonstrate that generalist birds affect fruit‐set of flowering trees.

Latitudinal Gradients in Position and Climatology of Upper Tree Limits Across Europe

open access: yesJournal of Biogeography, Volume 53, Issue 7, July 2026.
ABSTRACT Aim The upper tree limit (UTL) marks the upper boundary of the realized niche of trees. It is commonly located below the treeline, which represents the cold boundary of the fundamental niche of trees. We hypothesized that the elevational offset between the UTL and the treeline is partly systematic and can be predicted using topographic and ...

Plant Responses to Climate Change: The Case Study of Betulaceae and Poaceae Pollen Seasons (Northern Italy, Vignola, Emilia-Romagna)

open access: yesPlants, 2016
Aerobiological data have especially demonstrated that there is correlation between climate warming and the pollination season of plants. This paper focuses on airborne pollen monitoring of Betulaceae and Poaceae, two of the main plant groups with ...

Seeing herbaria in a new light: leaf reflectance spectroscopy unlocks trait and classification modeling in plant biodiversity collections

open access: yesNew Phytologist, Volume 251, Issue 2, Page 811-829, July 2026.
Summary Reflectance spectroscopy is a rapid method for estimating traits and discriminating species. Spectral libraries from herbarium specimens represent an untapped resource for generating broad phenomic datasets across space, time, and taxa. We conducted a proof‐of‐concept study using trait data and spectra from herbarium specimens up to 179 yr old,

Assessment of genetic diversity in natural European hophornbeam (Ostrya carpinifolia Scop.) populations in Turkey

open access: yesBiotechnology & Biotechnological Equipment, 2016
Genetic diversity is a crucial component for plant survivability and fitness in terms of adaptation, genetic stability and variability. In this study, a total of 160 genotypes were investigated using 12 random amplified polymorphic DNA (RAPD) primers to ...
