Life history stability under climate change: a wildflower at the northern edge of its range
Nordic Journal of Botany, EarlyView.Stabilities of life history traits for a widespread native perennial wildflower, Rudbeckia laciniata L., are described for five populations near the northern edge of its range in North America. Theory proposes that such populations experience variable levels of stress as suitable abiotic conditions shift north or south from year to year, which ...

A new old species of Tetracera (Dilleniaceae) from Espinhaço Range, Brazil
Nordic Journal of Botany, EarlyView.Tetracera is the only genus within Dilleniaceae with a pantropical distribution. During efforts for a taxonomic revision of the neotropical species, we identified incongruences between application of names and their taxonomic identities, based on protologue and type specimen analysis. Here we describe a new species for the genus bearing a single carpel

The effect of 2,4-D and kinetin on dedifferentiation of petiole cells in Arabidopsis thaliana
, 2012 Phytohormones are indispensable factors regulating plant cell dedifferentiation. In this paper, different concentrations of 2,4-dichlorophenoxyacetic acid (2,4-D) and kinetin (KIN) were incorporated in the culture medium and the anatomy of ...

Two new endemic species of Portulaca (Portulacaceae) from the Brazilian Pampa grasslands
Nordic Journal of Botany, EarlyView.Portulaca L. is a monophyletic, cosmopolitan genus of succulent plants comprising ca 153 species, with particularly high diversity in xerophytic ecosystems in tropical and subtropical regions. Based on morphological evidence, we describe and illustrate two new species from the Brazilian Pampa, Portulaca guaritensis and Portulaca guenoa.

Nordic Journal of Botany, EarlyView.Aiouea riedeliana (Kosterm.) P.L.R.Moraes and Brotto is the new combination for Cinnamomum riedelianum Kosterm., whose type‐bringing synonym is Persea riedelii Meisn. The placement of this taxon in Aiouea is presented, justified, and illustrated here, disagreeing with its previous classification in Ocotea, as Ocotea riedeliana (Kosterm.) Kottaim., then

Polymer Engineering &Science, EarlyView.Cellulose nanocrystals extracted from Mauritia flexuosa petiole were combined with MCM‐41 mesoporous silica to create a diclofenac‐loaded hybrid nanocomposite. Incorporation into electrospun PVA scaffolds enabled controlled diclofenac release and high cell viability, highlighting their potential for localized drug delivery.

PLANTS, PEOPLE, PLANET, EarlyView.There is an increasing risk of drought and salinisation of soil and groundwater globally, including in Pacific Island countries such as Tonga. Irrigating crops with slightly saline water, such as that produced by emerging desalination technologies, could help to alleviate droughts.
