A longer-term perspective on human exploitation and management of peat wetlands: the Hula Valley, Israel [PDF]

open access: yesMires and Peat, 2012
The influence of non-recent human activities on the structure and functioning of wetlands is frequently overlooked. The Hula wetland in northern Israel was exploited for a variety of resources over thousands of years prior to near-total destruction by ...

Record growth of Sphagnum papillosum in Georgia (Transcaucasus): rain frequency, temperature and microhabitat as key drivers in natural bogs

open access: yesMires and Peat, 2016
(1) Peatmoss (Sphagnum) growth has been studied widely, in particular at temperate and boreal latitudes > 45 °N, where productivity is mainly controlled by mean annual temperature and precipitation.

Biomarkers and inorganic proxies in the paleoenvironmental reconstruction of mires: The importance of landscape in Las Conchas (Asturias, Northern Spain) [PDF]

open access: yes, 2016
We determined the lipid distributions (n-alkanes, n-alkan-2-ones, n-alkanoic acids), total organic carbon (TOC), total nitrogen (TN), Ca/Mg and ash content in Las Conchas mire, a 3.2 m deep bryophyte-dominated mire in Northern Spain covering 8000 cal yr ...

Effects of shading on relative competitive advantage of three species of Sphagnum [PDF]

open access: yesMires and Peat, 2015
(1) Sphagnum is an important genus of bryophytes holding 10–15 % of the terrestrial carbon stock. With climate change a drier surface may increase the abundance of vascular plants on peatlands, so shading of Sphagnum may increase. Here we describe growth

Genesis and abiotic characteristics of three high-altitude peatlands in the Tien Shan Mountains (Kyrgyzstan), with focus on silty peatland substrates [PDF]

open access: yesMires and Peat, 2016
Peatlands are scarce and threatened ecosystems in the semiarid region of Kyrgyzstan. Knowledge about the Kyrgyz peatlands is still poor and, especially, their genesis has hardly been investigated so far.

Utilisation d'un filtre presse pour la clarification des bourbes de moûts blancs après décantation statique. Comparaison avec la centrifugation

open access: yesOENO One, 1989
Les auteurs étudient la clarification des bourbes de moûts blancs avec un filtre presse équipé de plateaux à membrane. L'addition d'un adjuvant sous forme de perlite (BECOLITE 5000, perméabilité 2,100 Darcy) à la dose de 1.500 g par hectolitre permet d ...

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Tau acetylation at K331 has limited impact on tau pathology in vivo

open access: yesFEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.
