Range shifts (especially during the Pleistocene), polyploidisation and hybridization are major factors affecting high-mountain biodiversity. A good system to study their role in the European high mountains is the Doronicum clusii aggregate (Asteraceae), whose four taxa (D. clusii s.s., D. stiriacum, D. glaciale subsp. glaciale and D. glaciale subsp. calcareum) are differentiated geographically,...

background and objectives: commiphora habessinica (o.berg) engl. (burseraceae), boswellia sacra flueck (burseraceae), phoenix dactylifera l. (arecaceae), and doronicum glaciale (wulfen) nyman (asteraceae) are of ethnomedicinal importance in persian folk medicine and are widely used to treat infectious diseases. the aim of the present study was to investigate the antimicrobial properties of thes...

Mid- to high-latitude fjordic coastal environments experience naturally variable salinity regimes. Climate projections suggest that freshwater input into the coastal ocean will increase in the future, exposing coastal organisms to further periods of reduced salinity. This study investigated the effect of low salinity on Lithothamnion glaciale, a red coralline alga found in mid- to high-latitude...

The name Doronicum thibetanum Cavill. has been inadvertently applied in herbarium labels to designate a species distributed in central China (provinces of Gansu and Sichuan). However, the study of the type specimen reveals that it is actually a species of Aster. The central Asian species of Doronicum has no available name and is thus here described as D. cavillieri Álv. Fern. & Nieto Fel. This ...

BACKGROUND Doronicum austriacum Jacq., Asteraceae, is a plant which is used in traditional alpine medicine. Historical sources describe the medical use of the root, but up until now only a few studies evaluated its pharmacological properties. The evaluation of the dichloromethane extract, and its major compounds for their anti-inflammatory and anti-oxidant potential was performed in macrophages...

The morphological characteristics of the eyes and the retinae of lanternfish larvae of Lampanyctus crocodilus, Benthosema glaciale, and Myctophum punctatum were analyzed in pre-flexion, flexion, and post-flexion stages. Pre-flexion larvae of L. crocodilus, the species with the shallowest depth distribution, had spherical eyes located antero-laterally on a strongly laterally-compressed head, sug...

We investigated rhodoliths (coralline red algae) from a subtropical ocality in the Gulf of California (Lithotharnniurn crassiusculurn) and a subarctic locality in Newfoundland (Lithotharnniurn glaciale) for their potential as paleoenvironmental rchives using microanalytical geochemical techniques tomeasure variations in ;5•80, Mg, and Ca. Rhodoliths are potentially well suited as recorders of s...

A bottom-mounted upward-facing 38-kHz echo sounder was deployed at ~400 m and cabled to shore in Masfjorden (~60°52'N, ~5°24'E), Norway. The scattering layers seen during autumn (September-October) 2008 were identified by trawling. Glacier lanternfish (Benthosema glaciale) were mainly distributed below ~200 m and displayed three different diel behavioral strategies: normal diel vertical migrati...

Rising atmospheric CO2 concentrations could cause a calcium carbonate subsaturation of Arctic surface waters in the next 20 yr, making these waters corrosive for calcareous organisms. It is presently unknown what effects this will have on Arctic calcifying organisms and the ecosystems of which they are integral components. So far, acidification effects on crustose coralline red algae (CCA) have...
