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

open access: yesNordic Journal of Botany, EarlyView.
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.

Molecular Phylogenetics of Bromus (Poaceae: Pooideae) Based on Chloroplast and Nuclear DNA Sequence Data [PDF]

open access: yes, 2007
We conducted a phylogenetic analysis to characterize relationships among Bromus and test the monophyly of five of the seven morphologically distinct groups within Bromus (Poaceae: Pooideae) that have been treated as sections, subgenera, or genera.

Is a plant truly plastic? Nutrients and neighbours induce trait‐specific responses, but performance depends on response direction

open access: yesOikos, EarlyView.
Plants live in a heterogeneous world, where nutrient and neighbour distributions vary in space and time. Plants can respond to this variation through plastic responses in individual organs, which are assumed to be coordinated among traits to support a coherent, adaptive strategy, maintaining plant growth in varying environments.

Harmonising digitised herbarium data to enhance biodiversity knowledge: Major steps towards an updated checklist for the flora of Greenland

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Herbaria worldwide hold centuries of plant data that are key to understanding and protecting biodiversity; however, even with increased digital access, differences in plant naming systems make it difficult to compare records. We developed a semi‐automated workflow that standardises species names and organises herbaria records from multiple institutions

Digitization connects scattered specimens and enables new historical research: Plants from the Lady Franklin Bay Expedition (1881–1884)

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Widespread museum digitization initiatives have made the world's herbaria more accessible than ever, launching a renaissance of specimen use. We highlight the value of digitization to bolster both scientific and historical research using the specimens from the Lady Franklin Bay Expedition (1881–1884) to the Canadian arctic, remembered for its tragedy ...
