Corrigendum to “Pollen-based paleoenvironmental and paleoclimatic change at Lake Ohrid (south-eastern Europe) during the past 500 ka” published in Biogeosciences, 13, 1423–1437, 2016 [PDF]

, 2018
In this corrigendum we report an updated pollen record from the Lake Ohrid DEEP site spanning the past 500 ka whereby we have reprocessed and re-analyzed 104 samples affected by chemical procedure problems that occurred in one palynological laboratory ...

Effect of soil waterlogging on below-ground biomass allometric relations in Norway spruce [PDF]

, 2010
An increasing importance is assigned to the estimation and verification of carbon stocks in forests. Forestry practice has several long-established and reliable methods for the assessment of aboveground biomass; however we still miss accurate predictors ...

Linking forest diversity and tree health: preliminary insights from a large-scale survey in Italy [PDF]

, 2018
Forest health is currently assessed in Europe (ICP Forests monitoring program). Crown defoliation and dieback, tree mortality, and pathogenic damage are the main aspects considered in tree health assessment. The worsening of environmental conditions (i.e.

Somatic embryogenesis of selected spruce species (Picea abies, P. omorika, P. pungens 'Glauca' and P. breweriana)

Acta Societatis Botanicorum Poloniae, 2011
Somatic embryogenesis was studied in four spruce species (Picea abies, P. omorika, P. pungens 'Glauca' and P. brewenana) to determine if this method can be used for in vitro propagation of coniferous trees.

Tree defence and bark beetles in a drying world: carbon partitioning, functioning and modelling. [PDF]

, 2020
Drought has promoted large-scale, insect-induced tree mortality in recent years, with severe consequences for ecosystem function, atmospheric processes, sustainable resources and global biogeochemical cycles.

Expanded application to plant reproductive tissues of a branched DNA probe‐based in situ hybridization method

Applications in Plant Sciences, EarlyView.
Abstract Premise Detecting clear tissue‐ and organ‐specific patterns of gene expression is key to understanding the genetic mechanisms that control plant development. In situ hybridization (ISH) of mRNA is one of the most precise, yet most challenging approaches to gene expression assays.

Evaluation of survival and growth of Picea abies (L.) H. Karst. and Picea obovata Ledeb. provenances in the north of Russia

Journal of Forest Science, 2017
Adaptation variability and ecological plasticity in the "genotype-environment" system of 22 provenances of Picea abies (Linnaeus) H. Karsten, Picea obovata (von Ledebour) and their introgressive hybrids growing within the Russian Plain were studied ...

Temporal variations in English Populations of a forest insect pest, the green spruce aphid (Elatobium abietinum), associated with the North Atlantic Oscillation and global warming [PDF]

, 2007
Based on an exceptionally long modern ecological dataset (41 years), it has been possible to show that warm weather in England associated with a positive North Atlantic Oscillation (NAO) index causes the spring migration of the green spruce aphid ...

Enabling the study of gene function in gymnosperms: Virus‐induced gene silencing in Ephedra tweedieana

Applications in Plant Sciences, EarlyView.
Abstract Premise As the sister clade to angiosperms, extant gymnosperms are crucial for reconstructing ancestral gene regulatory networks in seed plants. This highlights the need for model systems representing each of their distinct lineages. However, tools to quickly and effectively investigate gene function in gymnosperms are still limited due to the

Morpho-anatomical characteristics and content of nutritive macro elements in needles of fir and spruce and their varieties in Serbia [PDF]

Archives of Biological Sciences, 2013
The aim of the study is to establish, based on the morphological characteristics of shoots and morpho-anatomical characteristics of needles as well as the content of micro-elements in needles, whether there are differences between Pyramidal Fir (
