A potential, but not very widespread source of water is the presence of near-ground clouds, mostly fog. In this study, we investigate fog-low stratus (FLS) frequencies in Corsica, derived from a data set of Meteosat Second Generation SEVIRI, whereby a distinction between fog and low stratus is hardly feasible using remote sensing data. The FLS frequency was studied with respect to its interaction with distinct locally-generated wind and its dependence on the planetary boundary layer height (PBLH) obtained by ERA5 reanalysis (the fifth generation of the European Centre for Medium-Range Weather Forecasts, ECMWF). Results show that radiation FLS is formed in coastal areas at sunrise, with low PBLH. On the other hand, in the interior of the island at sunset, a maximum of advection FLS is formed, fostered by locally-generated and related transport of moisture. On the east side of the island, FLS frequency is lower throughout the year due to frequent lee situations. This situation is reinforced by reduced synoptic moisture transport by westerly winds, so that westerly exposed slopes benefit from moisture input by FLS formation.}, language = {en} } @misc{NeyretLeProvostBoesingetal., author = {Neyret, Margot and Le Provost, Ga{\"e}tane and Boesing, Andrea Larissa and Schneider, Florian D. and Baulechner, Dennis and Bergmann, Joana and Vries, Franciska T. de and Fiore-Donno, Anna Maria and Geisen, Stefan and Goldmann, Kezia and Merges, Anna and Saifutdinov, Ruslan A. and Simons, Nadja K. and Tobias, Joseph A. and Zaitsev, Andrey S. and Gossner, Martin M. and Jung, Kirsten and Kandeler, Ellen and Krauss, Jochen and Penone, Caterina and Schloter, Michael and Schulz, Stefanie and Staab, Michael and Wolters, Volkmar and Apostolakis, Antonios and Birkhofer, Klaus and Boch, Steffen and Boeddinghaus, Runa S. and Bolliger, Ralph and Bonkowski, Michael and Buscot, Fran{\c{c}}ois and Dumack, Kenneth and Fischer, Markus and Gan, Huei Ying and Heinze, Johannes and H{\"o}lzel, Norbert and John, Katharina and Klaus, Valentin H. and Kleinebecker, Till and Marhan, Sven and M{\"u}ller, J{\"o}rg and Renner, Swen C. and Rillig, Matthias C. and Schenk, No{\"e}lle V. and Sch{\"o}ning, Ingo and Schrumpf, Marion and Seibold, Sebastian and Socher, Stephanie A. and Solly, Emily F. and Teuscher, Miriam and Kleunen, Mark van and Wubet, Tesfaye and Manning, Peter}, title = {A slow-fast trait continuum at the whole community level in relation to land-use intensification}, series = {Nature Communications}, volume = {15}, journal = {Nature Communications}, number = {1}, issn = {2041-1723}, doi = {10.1038/s41467-024-45113-5}, abstract = {AbstractOrganismal functional strategies form a continuum from slow- to fast-growing organisms, in response to common drivers such as resource availability and disturbance. However, whether there is synchronisation of these strategies at the entire community level is unclear. Here, we combine trait data for 2800 above- and belowground taxa from 14 trophic guilds spanning a disturbance and resource availability gradient in German grasslands. The results indicate that most guilds consistently respond to these drivers through both direct and trophically mediated effects, resulting in a 'slow-fast' axis at the level of the entire community. Using 15 indicators of carbon and nutrient fluxes, biomass production and decomposition, we also show that fast trait communities are associated with faster rates of ecosystem functioning. These findings demonstrate that 'slow' and 'fast' strategies can be manifested at the level of whole communities, opening new avenues of ecosystem-level functional classification.}, language = {en} } @misc{CharisseErusPomponioetal., author = {Chariss{\´e}, Daniel and Erus, Guray and Pomponio, Raymond and Gorges, Martin and Schmidt, Nele and Schneider, Christine and Liepelt-Scarfone, Inga and Riedel, Oliver and Reetz, Kathrin and Schulz, J{\"o}rg B. and Berg, Daniela and Storch, Alexander and Witt, Karsten and Dodel, Richard and Kalbe, Elke and Kassubek, Jan and Hilker-Roggendorf, R{\"u}diger and Baudrexel, Simon}, title = {Brain age and Alzheimer's-like atrophy are domain-specific predictors of cognitive impairment in Parkinson's disease}, series = {Neurobiology of Aging}, volume = {109}, journal = {Neurobiology of Aging}, issn = {0197-4580}, doi = {10.1016/j.neurobiolaging.2021.08.020}, pages = {31 -- 42}, abstract = {Recently, it was shown that patients with Parkinson's disease (PD) who exhibit an "Alzheimer's disease (AD)-like" pattern of brain atrophy are at greater risk for future cognitive decline. This study aimed to investigate whether this association is domain-specific and whether atrophy associated with brain aging also relates to cognitive impairment in PD. SPARE-AD, an MRI index capturing AD-like atrophy, and atrophy-based estimates of brain age were computed from longitudinal structural imaging data of 178 PD patients and 84 healthy subjects from the LANDSCAPE cohort. All patients underwent an extensive neuropsychological test battery. Patients diagnosed with mild cognitive impairment or dementia were found to have higher SPARE-AD scores as compared to patients with normal cognition and healthy controls. All patient groups showed increased brain age. SPARE-AD predicted impairment in memory, language and executive functions, whereas advanced brain age was associated with deficits in attention and working memory. Data suggest that SPARE-AD and brain age are differentially related to domain-specific cognitive decline in PD. The underlying pathomechanisms remain to be determined.}, language = {en} } @misc{HaeusserAryalBarthetal., author = {H{\"a}usser, Martin and Aryal, Sugam and Barth, Johannes A.

The present study quantifies the variability of xylogenesis along an elevation gradient on the Mediterranean island of Corsica, where two native pine species (Pinus nigra Arnold ssp. laricio Maire and Pinus pinaster Aiton) grow from the upper tree line to sea level, partly in sympatry. We extracted microcores from 35 trees at 5 sites along an East-West transect from the coasts (10 m asl) to the island's central mountain ridge (1600 m asl) during bi-weekly sampling campaigns between 2017 and 2019. We applied generalised additive models to detect radial growth differences in elevation and species along with minimum temperatures for growth initiation. We found that trees in low elevations experienced over 2 months longer growth periods with higher maximum growth rates than in high elevations. The results show a 1-month delay for the beginning of tracheid formation between the low, mid and high-elevation belts but comparable timing for its termination. At the sites where both species co-occur, P. nigra accumulates more radial cells in a shorter time than P. pinaster. Trees at the two contrasting coastal sites have similar growth period lengths, but exhibit a time shift of over a month. Minimum temperatures around growth initiation vary between 3.1 °C for P. nigra and 9.9 °C for P. pinaster. These findings emphasise the high plasticity in the growth behaviour of one of the most widespread tree genera in Mediterranean and temperate zones.}, language = {en} } @misc{VossZahediAzadErnstetal., author = {Voss, Heike and Zahedi-Azad, Setareh and Ernst, Owen C. and Lucaßen, Jan and Mann, Guido and Bonse, J{\"o}rn and Boeck, Torsten and Martin, Jens and Schmid, Martina and Kr{\"u}ger, J{\"o}rg}, title = {Chemical vapor deposition of indium precursors for solar micro-absorbers using continuous laser radiation}, series = {Applied physics.
