Species specific and environment induced variation of δ13C and δ15N in alpine plants

open access: yesFrontiers in Plant Science, 2015
Stable carbon and nitrogen isotope signals in plant tissues integrate plant-environment interactions over long periods. In this study, we hypothesized that humid alpine life conditions are narrowing the scope for significant deviations from common carbon,

The Linnaean revolution – A history of the Natural System

open access: yesTAXON, Volume 74, Issue 5, Page 1011-1034, October 2025.
Abstract A very brief history of the Natural System (NS) is presented, focusing on angiosperms. The account is divided into four parts. The first, “Setting the stage”, gives an outline of my understanding of evolutionary ontology and how this reflects on taxonomy.

Chromosome dynamics visualized with an anti-centromeric histone H3 antibody in Allium.

open access: yesPLoS ONE, 2012
Due to the ease with which chromosomes can be observed, the Allium species, and onion in particular, have been familiar materials employed in cytogenetic experiments in biology.

RepeatOBserver: Tandem Repeat Visualisation and Putative Centromere Detection

open access: yesMolecular Ecology Resources, Volume 25, Issue 7, October 2025.
ABSTRACT Tandem repeats play an important role in centromere structure, subtelomeric regions, DNA methylation, recombination and the regulation of gene activity. Analysis of their distribution in genomes offers a potential means for predicting putative centromere locations, which continues to be a challenge for genome annotation.

Environmental effects of the Manganui ski field, Mt Taranaki/Egmont [PDF]

open access: yes, 2012
During May 2012, the environmental effects of the Manganui ski field were examined. Permanent quadrats first established in 1974 to monitor vegetation changes were re-measured, vegetation mapping was conducted, modifications to ground form and drainage ...

Foraging behaviour and occupation pattern of beef cows on a heterogeneous pasture in the Swiss Alps

open access: yesCzech Journal of Animal Science, 2014
In the Alps, many summer pastures are under-used due to the decreasing number of livestock. Optimizing the grazing management of heterogeneous pastures implies a better understanding of foraging habits of cattle.

Microscale Plant Diversity in Traditional Wood‐Pastures

open access: yesApplied Vegetation Science, Volume 28, Issue 4, October/December 2025.
Solitary trees shape wood–pasture plant communities by altering light and soil nutrients conditions. While canopies favor few shade‐tolerant species, open areas support more diverse species, and together these contrasting communities enhance biodiversity and functional trait variation at the landscape scale.

In vitro germination of four herbaceous species endemic to the Azores archipelago [PDF]

open access: yes, 2012
Current projects aimed at the conservation of endemic species and restorations of native habitats require information about seed viability, held in a germplasm bank, and ex situ seed and plant production.
