Acorn size is more important than nursery fertilization for outplanting performance of Quercus variabilis container seedlings
By Isabelle Fabrissin On 26 March 2019 In All published articles, Data in repository, Research paper
Small acorns are usually discarded for seedling cultivation because they reduce plant quality. This, however, can potentially reduce genetic diversity of plantations. The use of small acorns will result in the production of a higher proportion of

Efficiency of post-stratification for a large-scale forest inventory—case Finnish NFI
By Isabelle Fabrissin On 25 March 2019 In All published articles, Open Access, Research paper, Special issue/Topical collection
Post-stratification based on remotely sensed data is an efficient method in estimating regional-level results in the operational National Forest Inventory. It also enables calculating the results accurately for smaller areas than with the default method of using

Is tree age or tree size reducing height increment in Abies alba Mill. at its southernmost distribution limit?
By Isabelle Fabrissin On 22 March 2019 In All published articles, Data in repository, Research paper
Conventional methods for estimating the current annual increment of stand volume are based on the uncertain assumption that height increment decreases with tree age. Conversely, size, rather than age, should be accounted for the observed senescence-related declines

Negative correlation between ash dieback susceptibility and reproductive success: good news for European ash forests
By Isabelle Fabrissin On 21 March 2019 In All published articles, Data in repository, Research paper
European ash ( Fraxinus excelsior L.) trees with low susceptibility to ash dieback have higher reproductive fitness compared to highly susceptible trees, although most pronounced for female success. Selection at generation turnover therefore supports the future recovery

The age of black pine (Pinus nigra Arn. ssp. salzmannii (Dunal) Franco) mother trees has no effect on seed germination and on offspring seedling performance
By Isabelle Fabrissin On 20 March 2019 In All published articles, Research paper, Special issue/Topical collection
We sampled Pinus nigra cones in 29 trees in an age range of 90 to 725 years. The mother tree age did not significantly influence the pinecone or pine seed size, seed germination capacity, or plant size

Climate change and mixed forests: how do altered survival probabilities impact economically desirable species proportions of Norway spruce and European beech?
By Isabelle Fabrissin On 28 February 2019 In All published articles, Research paper, Special issue/Topical collection
Economic consequences of altered survival probabilities under climate change should be considered for regeneration planning in Southeast Germany. Findings suggest that species compositions of mixed stands obtained from continuous optimization may buffer but not completely mitigate economic

Fine root morphology and growth in response to nitrogen addition through drip fertigation in a Populus × euramericana “Guariento” plantation over multiple years
By Isabelle Fabrissin On 27 February 2019 In All published articles, Data in repository, Research paper
Nitrogen addition through drip fertigation to a poplar plantation ( Populus × euramericana “Guariento”) promoted fine root growth only in the early period. The relationship between root growth and soil N content was positive in the first

Declining fruit production before death in a widely distributed tree species, Sorbus aucuparia L.
By Isabelle Fabrissin On 25 February 2019 In All published articles, Data in repository, Research paper
Trees are commonly thought to increase their seed production before death. We tested this terminal investment hypothesis using long-term data on rowan trees ( Sorbus aucuparia ) and found no support. Rather, seed production declined significantly before

Biology and distribution of Agrilus macer LeConte (Coleoptera: Buprestidae), a species associated with sugarberry (Celtis laevigata Willd.) mortality in the southeastern USA
By Isabelle Fabrissin On 22 February 2019 In All published articles, Research paper, Special issue/Topical collection
Agrilus macer is attacking sugarberry trees in the southeastern USA, a region from which few specimens have been previously collected. Despite attacking at high densities, this species appears to be a secondary pest, and there is no

Temporal and spatial high-resolution climate data from 1961 to 2100 for the German National Forest Inventory (NFI)
By Isabelle Fabrissin On 21 February 2019 In All published articles, Data in repository, Data paper, Open Access, Special issue/Topical collection
The “NFI 2012 environmental data base climate” is part of the environmental database of the German National Forest Inventory. It contains climate information for 26,450 inventory points generated from gridded daily climate data for 1961–2100 at a
