Spontaneous bleeding in chronic kidney disease: global coagulation assays may predict bleeding risk

open access: yesResearch and Practice in Thrombosis and Haemostasis
Background: Chronic kidney disease (CKD) is associated with increased bleeding and thrombotic risks. Standard blood tests do not sufficiently quantify these risks.

Generalist‐pollinated Arabis alpina exhibits floral scent variation at multiple scales

open access: yesNordic Journal of Botany, EarlyView.
Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant‐pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and ...

Temporal and spatial variation in bacterial communities of “Jonagold” apple (Malus x domestica Borkh.) and “Conference” pear (Pyrus communis L.) floral nectar

open access: yesMicrobiologyOpen, 2019
Production of many agricultural crops and fruits strongly depends on pollinators. For instance, pome fruits such as apple and pear are highly dependent on pollination for fruit set, fruit quality, and yield.

Sex-Dependent Variation of Pumpkin (Cucurbita maxima cv. Big Max) Nectar and Nectaries as Determined by Proteomics and Metabolomics

open access: yesFrontiers in Plant Science, 2018
Nectar is a floral reward that sustains mutualisms with pollinators, which in turn, improves fruit set. While it is known that nectar is a chemically complex solution, extensive identification and quantification of this complexity has been lacking ...

Sedum zhenghaianum (Crassulaceae), a new species from Zhejiang and Jiangxi, East China

open access: yesNordic Journal of Botany, EarlyView.
In this paper, Sedum zhenghaianum sp. nov. is described as a new species based on morphological and molecular analyses, and its taxonomic relationships are discussed. Morphological analysis indicates that S. zhenghaianum should be classified in the genus Sedum sect. Sedum and is distinct from the related species S. tosaense in morphology, e.g.

Fast determination of biogenic amines in beverages by a core-shell particle column [PDF]

open access: yes, 2015
A fast and reliable HPLC method for the determination of 11 biogenic amines in beverages has been performed. After pre-column derivatization with dansyl-chloride a Kinetex C18 core–shell particle column (100 mm × 4.6 mm, 2.6 μm particle size) has been ...

Effect of Abiotic Factors on Nectar Quality and Secretion of Two Early Spring Species, Galanthus nivalis L. and Helleborus niger L.

open access: yesDiversity
Floral nectar is mainly a reward in the form of food for pollinators. In early spring, when snow can still be present, pollinators have trouble finding food.

Unraveling cryptic lineages in Jatropha nana: phylogenetic evidence supports species status for J. benghalensis (Euphorbiaceae)

open access: yesNordic Journal of Botany, EarlyView.
The taxonomic framework of the genus Jatropha (Euphorbiaceae) is well established, but its geophytic species present significant classification challenges. These difficulties arise from species complexes, cryptic traits, and high environmental and phenotypic variability.

Nectar Production by Invasive Lantana camara and Endemic L. peduncularis in the Galápagos Islands [PDF]

open access: yes, 2012
Measurements of nectar volume and sugar concentration along two elevational gradients, in flower exclusion experiments, and over a diurnal cycle of nectar production, were compared for invasive Lantana camara and endemic Lantana peduncularis in the ...

Nectar Production and Three Main Sugars in Nectar of Salvia pratensis and Salvia glutinosa in Correlation with Abiotic Factors

open access: yesAgriculture
Floral nectar is mainly a reward in the form of food for pollinators. Its composition plays an important role when pollinators choose their food. Several studies have shown that the popularity of flowers with nectar is influenced by the concentration and
