Can we use dendrogeomorphology for the spatial and temporal analysis of less intensive mass movement processes?: A case study of three debris flows in NW and W Slovenia

open access: yesActa Silvae et Ligni, 2021
Debris flows can transport large amounts of material and therefore present a significant threat to infrastructure and human life. In this research, we used tree-ring width analyses to quantify the response of trees to three debris flow events in NW ...

Auswirkungen der Einbringung von Buche (Fagus sylvatica L.) auf die Artendiversität und Naturnähe von Nadelholzbeständen in Niedersachsen [PDF]

open access: yes, 2013
The promotion and extension of continuous cover mixed stands with a simultaneous reduction of conifer-monocultures play a major role in current silvicultural practices in Central Europe.

Hermit beetle (Osmoderma barnabita) habitat selection and movement are shaped by tree microhabitat availability in Eastern Romanian Carpathians

open access: yesInsect Conservation and Diversity, EarlyView.
We conducted the first radio‐tracking study on Osmoderma barnabita to examine the movement ecology and habitat selection in the Eastern Carpathians. A female recorded the longest movement distance and had larger home ranges than males. It showed a preference for Quercus petraea, with wood mould cavities and DBH as key predictors.

X-ray tomography as a tool for detailed anatomical analysis [PDF]

open access: yes, 2009
Wood identification, anatomical examination and retrieval of quantitative information arc important aspects of many research disciplines. Conventional light microscopy with a camera and (semi)automatic image analysis software is an often used methodology

Tree growth response and adaptation to climate change and climate extremes: From canopy to stem

open access: yesJournal of Integrative Plant Biology, EarlyView.
This review synthesizes the responses and adaptations of tree growth, including canopy phenology, intra‐annual wood formation dynamics, and annual stem growth, to climate change and climate extremes. It highlights key knowledge gaps for future research to support sustainable forest management and enhance forest carbon storage under ongoing climate ...

Elevation, rather than land use, causes important dietary shifts in the Mediterranean golden eagle

open access: yesJournal of Zoology, EarlyView.
In an ever‐changing landscape, golden eagles in the Iberian Peninsula demonstrate remarkable dietary adaptability. We monitored 50 distinct breeding events over 4 years using camera traps, collecting over 520 000 images. Elevation, rather than land use, emerged as the main driver of prey composition: lagomorphs and columbiforms dominated at lower ...

The greenhouse diet : gypsy moth performance in a CO2-enriched world [PDF]

open access: yes, 2008
Rising atmospheric CO2 is regarded as the main driver of global warming (Crowley, 2000). While temperature changes directly affect plants and animals (Root et al., 2003; Parmesan, 2006), the effects of CO2 on herbivores are mediated through changes in ...

Tree‐ring structure determines the temporal coordination between xylem growth and the gain in hydraulic conductivity in the outermost ring

open access: yesNew Phytologist, EarlyView.
Summary The study of seasonal xylem hydraulics has predominantly focused on embolism‐induced losses, whereas growth‐driven increases in hydraulic capacity have received little attention. We assessed the intra‐annual dynamics of xylem formation and gain of conductivity in the current‐year ring of three species with contrasting tree‐ring structure ...

Population estimators or progeny tests: what is the best method to assess null allele frequencies at SSR loci? [PDF]

open access: yes, 2009
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.
