Small, protected habitat patches within boreal production forests contribute to biodiversity conservation
Matti Häkkilä, Anna Johansson, Terhi Sandgren, Anne Uusitalo, Mikko Mönkkönen, Pasi Puttonen & Sini Savilaakso
Small, protected habitat patches have a higher number of species and more deadwood than surrounding production forest areas although the number of individuals is similar. They have a similar number of species and individuals and deadwood volume compared to natural forests. However, species assemblages in small, protected habitat patches differ from both natural and production forests, which means they are not a substitute for larger protected areas.
Habitat preferences determine species’ response to forest management in boreal production forests of Fennoscandia and European Russia
Savilaakso, S., Johansson, A., Häkkilä, M., Uusitalo, A., Sandgren, T., Mönkkönen, M., & Puttonen, P.
Habitat preferences determine species’ response to forest management in boreal production forests of Fennoscandia and European Russia. Uneven-aged forest management shows a strong positive effect on species richness of forest dependent species when compared to even-aged forests less than 80 years old. A similar effect is noticed when young even-aged forests are compared to mature (>80 years old) even-aged forests. In young even-aged forests and forests having undergone retention harvest, open habitat species and their individuals are more numerous. Natural forests have overall more species than even-aged forests, especially forest dependent species, but have a similar number of species than uneven-aged forests.
Struvite precipitation is an effective technology for nutrient recovery from anaerobic digestate, while there is limited evidence to conclude the effectiveness of ammonia stripping
Dag Lorick, Biljana Macura, Marcus Ahlström, Anders Grimvall & Robin Harder
Struvite precipitation was found to be an effective technology for nutrient recovery from the liquid phase of anaerobic digestate. The precipitation process is most efficient at a pH of around 9.5 and higher molar ratio of magnesium to phosphate (up to 4:1) in liquid phase of anaerobic digestate. These conditions have a positive effect on phosphorus removal. The evidence base for ammonia stripping was limited and therefore no conclusive results about appropriate conditions for the most efficient nitrogen extraction could be made.
