Effect of permanent plots on the relative efficiency of spatially balanced sampling in a national forest inventory
Using spatially balanced sampling utilizing auxiliary information in the design phase can enhance the design efficiency of national forest inventory. These gains decreased with increasing proportion of permanent plots in the sample. Using semi-permanent plots, changing every

Forest stand productivity derived from site conditions: an assessment of old Douglas-fir stands (Pseudotsuga menziesii (Mirb.) Franco var. menziesii) in Central Europe
By Isabelle Fabrissin On 28 March 2019 In All published articles, Data in repository, Open Access, Research paper
Douglas-fir growth correlates with the climate, the soil moisture regime, and the soil nutrient status, reflecting a broad physiological amplitude. Even though planting this non-native tree species is suggested as a viable strategy to improve adaptiveness of

Demographic history and spatial genetic structure in a remnant population of the subtropical tree Anadenanthera colubrina var. cebil (Griseb.) Altschul (Fabaceae)
By Isabelle Fabrissin On 27 March 2019 In All published articles, Data in repository, Research paper
A remnant population of Anadenanthera colubrina var. cebil in Northern Argentina showed a mixed mating system, high genetic diversity, and moderate spatial genetic structure, which was stronger in saplings than in adults. Demographic history analyses revealed an

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
