Biomineralization of primary carbonate cements: a new biosignature in the fossil record from the Anisian of Southern Italy

open access: yesLethaia, EarlyView., 2021
Biomineralization is a generic term used to indicate biological‐mediated mineral formation. In carbonate mineralization, nucleation of crystals can be: (1) controlled directly by the organisms, like in the skeletal formation of most metazoans; (2) induced by microbial communities, by indirect precipitation mediated by their metabolic activities; or (3)

Re-introduction and present status of the lynx (<em>Lynx Lynx</em>) in Switzerland

open access: yesHystrix, the Italian Journal of Mammalogy, 1998
<strong>Abstract</strong> A lynx recovery programme started in Switzerland in 1970. From 1970-76, at least 14 lynx were translocated from the Carpathian Mountains into the Swiss Alps. Another re-introduction took place in the Jura Mountains,

Decoupling glacier retreat and surface stabilization on the Snežnik Plateau (Slovenia), insights from in situ cosmogenic 36Cl exposure and depth‐profile ages

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Glaciokarst landscapes pose distinctive challenges for cosmogenic dating because meltwater and runoff can be rapidly rerouted into ponors and conduit networks, weakening glacier–river coupling and promoting local sediment storage. We reconstruct glacier retreat and postglacial stabilization on the Snežnik Plateau (SW Slovenia) using in situ ...

Glacial refugia and speciation in a group of wind-pollinated and -dispersed, endemic Alpine species of Helictotrichon (Poaceae). [PDF]

open access: yesPLoS ONE, 2018
In the Alps phylogeographic studies indicate for small insect-pollinated herbs that climatic fluctuations caused significant population migrations and fragmentations into glacial refugia at the periphery of the Alps.

Lectotypifications and taxonomic changes in the holoparasitic Orobanchaceae

open access: yesNordic Journal of Botany, EarlyView.
Based on further extensive studies of specimens in various herbaria, lectotypes are designated for many taxa of holoparasitic Orobanchaceae. In particular, 47 names in the genera Boschniakia (incl. Xylanche), Cistanche, Orobanche, Phelipanche and Phelypaea are lectotypified.

Burial diagenesis, organic maturation and tectonic loading in the French subalpine chains, S.E. France [PDF]

open access: yes, 1992
The French Subalpine Chains of southeastern France lie on the western edge of the Western Alps. The area is the foreland fold/thrust belt to the main orogenic hinterland to the east.

open access: yesArachnologische Mitteilungen, 2005
New data on the sex ratio of 16 populations of the endemic harvestman Megabunus lesserti Schenkel, 1927 in the northeastern Alps confirm the previously assumed pattern of geographic parthenogenesis.

Rhagidiidae mites of the Western Italian Alps

open access: yes, 2023
In the pre-alpine areas of the Mediterranean basin fragmented underground environments have differentiated, probably almost unchanged since the Miocene (over 5 million years ago). These environments enabled long periods of colonization and geographical isolation for organisms, allowing the Rhagidiidae mites an evolutionary process of millions of years.
