The effect of forest fuel harvesting on the fungal diversity of clear-cuts
2012
Abstract The removal of logging residues and stumps from clear-cuts has become a common forestry practice. Forest fuel harvesting decreases the initially low volume of dead wood in managed forests, but the biodiversity effects are poorly known. We studied the effects of forest fuel harvesting on decomposer fungi on clear-cut Norway spruce stands in central Finland. The number of occurrences and taxa of polypores, saprotrophic agarics and pleurotoid agarics were determined on 10 forest fuel harvested and 10 control clear-cuts 4–5 years after logging. In total, we recorded 148 fungal taxa. The total number of taxa, the number of polypore occurrences, and the number of polypore species within …
Responses of polypore fungi following disturbance-emulating harvesting treatments and deadwood creation in boreal Norway spruce dominated forests
2019
ABSTRACTThe emulation of natural disturbances in harvesting has become a widely accepted approach to reach ecologically sustainable forest management. The purpose of this study was to examine the r...
Ecology, environmental requirements and conservation of corticioid fungi occupying small diameter dead wood
2016
The increasing human impact upon the biosphere of earth is causing profound changes across all spatial scales. The ability to cope with human-induced disturbance varies among organisms; specialist species are more negatively affected than generalist species. Forests are among the most heavily affected ecosystems; especially the dead wood associated organisms are in peril. The earlier research has strongly focused on large diameter dead wood and associated species. The aim of this thesis was to investigate small diameter dead wood and collect systematic information about species richness and abundance as well as habitat and substrate preferences of associated corticioid fungi. Fungal data wa…
Sūnu daudzveidība uz atmirušās koksnes egļu mežos saistībā ar koksnes vecumu un substrāta īpašībām
2015
Atmirusī koksne ir specifisks un dinamisks substrāts. Tā kalpo kā dzīves vide daudzām retām un tieši šim substrātam specifiskām sūnu sugām, kas norāda uz nepieciešamību veikt detalizētus pētījumus par atmirušo koksni kā sūnām nozīmīgu substrātu. Pētījumā salīdzināts sūnu sugu un funkcionālo grupu sastāvs uz dažādiem atmirušās koksnes veidiem (kritalām, stumbeņiem, sausokņiem), analizēta sūnu sugu un funkcionālo grupu bagātība saistībā ar atmirušās koksnes vecumu un substrāta parametriem (izmēri, sadalīšanās pakāpe). Kopumā uz visiem atmirušās koksnes veidiem konstatētas 53 sūnu sugas (40 lapu un 13 aknu sūnas). Novērotas atšķirības sūnu sugu sastāvā starp kritalām un stāvošu atmirušo koksni…

Dead wood profile of a semi-natural boreal forest – implications for sampling
2019
Dead wood profile of a forest is a useful tool for describing forest characteristics and assessing forest disturbance history. Nevertheless, there are few studies on dead wood profiles, including both coarse and fine dead wood, and on the effect of sampling intensity on the dead wood estimates. In a semi-natural boreal forest, we measured every dead wood item over 2 cm in diameter from 80 study plots. From eight plots, we further recorded dead wood items below 2 cm in diameter. Based on these data we constructed the full dead wood profile, i.e. the overall number of dead wood items and their distribution among different tree species, volumes of different size and decay stage categories. We …
