Using Annual Resolution Pollen Analysis to Synchronize Varve and Tree-Ring Records
Quaternary, 2019 Fossil wood and varved lake sediments allow proxy analysis with exceptionally high, (sub-)annual resolution. Both archives provide dating through ring and layer counting, yet with different accuracy.

New records of Malus crescimannoi (Rosaceae) in Sicily [PDF]
, 2016 New findings for Malus crescimmanoi, originally known from the mountain area near Floresta (Nebrodi Mts.). The new sites fall in Madonie Mts., where the species is found at the edge of Quercus petraea (Matt.) Liebl.

Plant Biology, EarlyView.Mature beech trees redistributed soil water, equal to ca. 10% of stand transpiration, from deeper moist soils to dry surface soils, where it was taken up by seedlings of different tree species. Abstract Hydraulic redistribution is considered a crucial dryland mechanism that may be important in temperate environments facing increased soil drying–wetting

Selected properties of European beech (Fagus sylvatica L.)
Journal of Forest Science, 2008 The paper deals with the variability of tree-ring width, with the density and swelling (volumetric swelling and swelling in individual anatomical directions) of wood from two different locations.

Plant Biology, EarlyView.Functional traits can explain significant tree growth reductions in response to the 2018–2020 drought for a wide set of 71 species including angiosperms and gymnosperms. Moreover, four distinct response types emerged: ‘Sufferer’, ‘Late sufferer’, ‘Recoverer’ and ‘Resister’, with gymnosperms predominately appearing as ‘Sufferer’ and ‘Late sufferer ...

Population estimators or progeny tests: what is the best method to assess null allele frequencies at SSR loci? [PDF]
Nuclear SSRs are notorious for having relatively high frequencies of null alleles, i.e. alleles that fail to amplify and are thus recessive and undetected in heterozygotes.

A first assessment of genetic variability in the longhorn beetle Rosalia alpina (Coleoptera: Cerambycidae) from the Italian Apennines [PDF]
, 2018 The Rosalia longicorn (Rosalia alpina) is a strictly protected saproxylic beetle, widely distributed in Central and Southern Europe and mainly associated with ancient beech forests. To improve knowledge about the conservation status of R. alpina in Italy,

Plant Biology, EarlyView.This study demonstrates the potential of the Sentinel‐1 Dual Polarimetric Radar Vegetation Index, combined with climate variables and the Standardized Precipitation–Evapotranspiration Index, to effectively detect and monitor drought‐induced stress in temperate broadleaf deciduous forests.

Are beech (Fagus sylvatica) roots territorial?
Forest Ecology and Management, 2010 Abstract Root competition between conspecific neighbours has been notoriously difficult to determine in intact ecosystems. Here we applied microsatellite markers to genotype beech trees (Fagus sylvatica, L.) and roots in subplots in an undisturbed, old-growth monospecific forest (Hainich, Germany).

Drought legacy in mature spruce alleviates physiological stress during recurrent drought
Plant Biology, EarlyView.The slow recovery of leaf area in mature spruce following a long‐term drought alleviated physiological stress during recurrent drought. Abstract Forest ecosystems are facing severe and prolonged droughts with delayed recovery, known as “drought legacy”.
