Long‐term trends in greenness in the alpine zone of northeastern North America from remote sensing

open access: yesEcosphere, Volume 17, Issue 9, September 2026.
Abstract Alpine zones above treeline in the Appalachian Mountains and adjacent ranges of northeastern North America support distinctive ecological communities that thrive where conditions are too harsh for trees to grow. These communities differ from alpine zones elsewhere on the continent and are a regionally important source of floristic biodiversity,

Effects of herbicide mixtures and additives on Rhododendron ponticum

open access: yes, 1993
The possibility of increasing the activity of glyphosate, imazapyr, sulfonylurea herbicides and triclopyr against Rhododendron ponticum L. was investigated using container-grown plants. Glyphosate, imazapyr and triclopyr alone and metsulfuron-methyl with

Diversity of fungi colonizing leaves of Rhododendron (Rhododendron L.) cuttings [PDF]

open access: yes, 2014
Rhododendrons (Rhododendron L.) are shrubs whose attractiveness is determined by their multi-coloured flowers and evergreen leaves. Necroses visible on the leaves of rhododendron cuttings diminish the suitability of nursery material for marketing.

Taxonomic revision of the genus Tzveleviochloa (Poaceae, Aveninae) in India

open access: yesNordic Journal of Botany, Volume 2026, Issue 9, September 2026.
The taxonomy of Tzveleviochloa in India is revised based on morphological evidence, comprehensive observations of herbarium specimens and field records, and several botanical explorations in the study area. The accepted diversity is increased from two to five species, including two recently described species. The genus is distributed in the Western and

The Comprehensive Root Metabolite–Rhizomicrobiota Response Patterns of Rhododendron delavayi (R. delavayi) to Waterlogging Stress and Post–Waterlogging Recovery

open access: yesHorticulturae
Waterlogging is a critical abiotic stressor that significantly impacts plant growth. Plants under waterlogging stress release metabolic signals that recruit rhizosphere microorganisms and enhance stress resistance.

Speciation with gene flow

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1476-1499, September 2026.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

Transcriptomic and Metabolomic Analyses Reveal Differing Phytohormone Regulation in Rhododendron Cultivars in Response to Azalea Lace Bug (Stephanitis pyrioides)

open access: yesHorticulturae
Rhododendron spp., valuable ornamental plants, frequently suffer from infestations of the azalea lace bug (Stephanitis pyrioides Scott, ALB). However, the hormonal regulatory mechanisms underlying Rhododendron defense against ALB are not well understood.
