Charlotta Harju, Katja Lähtinen. (2021). Perceptions of wooden interior product quality – insights on sustainability views among Finnish consumers. Silva Fennica vol. 55 no. 5 article id 10605. https://doi.org/10.14214/sf.10605
Keywords: wood products; consumer behavior; perceived quality; sociodemographic variables; sustainable consumption
Highlights: The quality indicators of wooden interior products can be grouped into four factors relating to products’ environmental friendliness, fit with lifestyle and home design, visual and tactile attractiveness, and technical solidity, which are in multiple ways connected with sustainability; The sociodemographic background of the respondents was found to be linked with consumer scores for those factors; Wooden interior products should be designed to meet different types of product quality expectations in the home environment.

Juha Kaitera, Leena Aarnio, Tiina Ylioja, Jouni Karhu. (2021). Naohidemyces vaccinii sporulates on wild species of ground flora in Finnish Norway spruce seed orchards but Thekopsora areolata does not on other species than Prunus. Silva Fennica vol. 55 no. 5 article id 10568. https://doi.org/10.14214/sf.10568
Keywords: Picea abies; cherry-spruce rust; epidemics; Prunus; blueberry rust; Naohidemyces vaccinii
Highlights: Cherry-spruce rust, Thekopsora areolata, was not found on any of the common species of ground vegetation in Finnish Norway spruce seed orchards; Blueberry rust, Naohidemyces vaccinii, was common on Vaccinium myrtillus and occasional on V. vitis-idaea in all seed orchards; Thekopsora areolata occurs only on Prunus in Finnish Norway spruce seed orchards.

Keywords: Picea abies; cherry-spruce rust; epidemics; rust diseases; Prunus; heteroecism
Highlights: Prunus is the only alternate host of cherry-spruce rust identified in this study; Cherry-spruce rust does not infect plants that belong to common ground vegetation flora in Finnish Norway spruce seed orchards; Spores from different Finnish cherry-spruce rust populations are similarly pathogenic on Prunus; Disease control should be focused only on Prunus in seed orchards.

Juha Kaitera, Jouni Karhu. (2020). Temperature range for germination of Thekopsora areolata aeciospores from Finnish Norway spruce seed orchards. Silva Fennica vol. 55 no. 1 article id 10422. https://doi.org/10.14214/sf.10422
Keywords: Picea abies; cherry-spruce rust; cones; epidemics; rust diseases
Highlights: Cherry-spruce rust was able to germinate at very low temperature (6 °C) close to the temperature when thermal growth starts; Optimum spore germination occurred between 15–24 °C; High temperature of 30 °C drastically reduced germination; Temperature had the most significant effect on germination, while spore source had less significant effect and agar media a non-significant effect on germination in a Fixed Effects model.

Keywords: ALS; DEM; forest road quality; reference DEM; unpaved forest road
Highlights: Airborne laser scanning is used to assess forest road quality; High-pulse data analysis classified roads with good performance; Two-step classification further improved the accuracy; A reference surface improved the classification results of the low pulse data; 66–75% of the roads were correctly classified using the reference surface.

Valdir Marcos Stefenon, Jordana Caroline Nagel, Igor Poletto. (2016). Evidences of genetic bottleneck and fitness decline in Luehea divaricata populations from southern Brazil. Silva Fennica vol. 50 no. 5 article id 1566. https://doi.org/10.14214/sf.1566
Keywords: demographic history; effective population size; genetic resources conservation; Pampa biome
Highlights: Signatures of genetic bottlenecks and reduction of populations’ fitness were observed in populations of Luehea divaricata in southern Brazil; Lower levels of observed heterozygosity are correlated with populations’ fitness, decreasing germination capacity and increasing the proportion of anomalous germinated plantlets; Promoting the connection among populations is proposed as a key strategy towards conservation of L. divaricata genetic resources in its southernmost distribution range.
