Xanthium strumarium - a potential cheap resource of plant substances for medicinal use [PDF]

open access: yes, 2019
Xanthium strumarium L. (Asteraceae) is an annual herb which reproduces solely by seed. So far its centre of origin was considered Central or South America. Recent archeological research revealed that the burs of X.

Micromorpho‐anatomical studies on the leaves and woods of Turkish Daphne (Thymelaeaceae) taxa

open access: yesNordic Journal of Botany, EarlyView.
The identification of Daphne taxa is difficult because of the lack of available morphological characteristics. Here, we aimed to describe leaf and wood micromorpho‐anatomical characteristics of native Turkish Daphne taxa (D. glomerata, D. gnidioides, D. mezereum, D. mucronata, D. oleoides subsp. kurdica, D. pontica and D.

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.

Darwin and the plants of the Galapagos-Islands [PDF]

open access: yes, 2009
During his five year sea voyage with the “Beagle”, Darwin, at the suggestion of the botanist J.S. Henslow, collected more than 1400 vascular plants, and more than 200 of them alone during his short stay on the Galápagos Islands.

Taxonomic and functional plant diversity of the Santorini-Christiana island group (Aegean Sea, Greece) [PDF]

open access: yes, 2019
This is the first attempt to analyse vascular plant diversity patterns regarding the seven vegetated islands of the Santorini archipelago (Aegean Sea, Greece) as a whole. Hitherto unpublished floristic records, combined with critical use of taxonomic and

Leveraging machine learning and citizen science data to describe flowering phenology across South Africa

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Recent shifts in flowering times are an index of, and a response to, human driven climate change. However, most information on these flowering changes is heavily skewed to the northern hemisphere. This imbalance limits our understanding of how climate change is affecting ecosystems, including the mismatches of flowering times between species, increased

Digitizing collections to unlock the full potential of palynology: A case study with the Smithsonian palynology collection

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Large palynological collections have been built over decades and contain vital information. However, they are often difficult to access and use effectively. What is the point of having such collections if they are not fully utilizable? To solve this problem, we digitized the Smithsonian palynological collection using both light and confocal microscopy.

An empirical assessment of a single family‐wide hybrid capture locus set at multiple evolutionary timescales in Asteraceae

open access: yesApplications in Plant Sciences, 2019
Premise Hybrid capture with high‐throughput sequencing (Hyb‐Seq) is a powerful tool for evolutionary studies. The applicability of an Asteraceae family‐specific Hyb‐Seq probe set and the outcomes of different phylogenetic analyses are investigated here ...
