Hakkuualoille j\u00e4tetyt kannot ovat yksi mahdollinen resurssi kaarnakuoriaisille. Kaarnakuoriaiset ovat kovakuoriaisia, jotka saattavat aiheuttaa mets\u00e4tuhoja tappamalla puita. Monien kaarnakuoriaislajien tiedet\u00e4\u00e4n iskeytyv\u00e4n juuri kuolleisiin sek\u00e4 puolustuskyvylt\u00e4\u00e4n heikentyneisiin puihin. Tietoa vanhenevista kannoista kaarnakuoriaisten resurssina ei kuitenkaan ole. T\u00e4m\u00e4n tutkimuksen tavoitteena oli selvitt\u00e4\u00e4 kuinka paljon reilun vuoden vanhat kuusen kannot houkuttelevat kaarnakuoriaisia avohakkuualoille. Tutkimus toteutettiin kes\u00e4ll\u00e4 2018 Jyv\u00e4skyl\u00e4ss\u00e4 kahdella avohakkuualalla. Aineisto ker\u00e4ttiin ristikkoikkunapyydyksill\u00e4, joita oli yhteens\u00e4 kymmenen molemmilla hakkuualoilla. Pyydyksi\u00e4 asetettiin yhdelle hakkuualalle viisi kannoille sek\u00e4 viisi avomaalle. Pyydystetyt kaarnakuoriaiset m\u00e4\u00e4ritettiin lajilleen Dryocoetes-sukua lukuunottamatta. Lajeja oli aineistossa yhteens\u00e4 11. Kaarnakuoriaisia saatiin yhteens\u00e4 839 yksil\u00f6\u00e4, joista kannoilla tuli 721 ja avomaalla olleisiin pyydyksiin 118, eli kannoille saatiin enemm\u00e4n kaarnakuoriaisia. Lajim\u00e4\u00e4r\u00e4 oli pienempi reilun vuoden vanhalla kuin tuoreella avohakkuualalla. My\u00f6s yksil\u00f6m\u00e4\u00e4r\u00e4 oli yli kolmasosan pienempi v\u00e4h\u00e4n yli vuoden vanhalla hakkuualalla. Saatujen tulosten mukaan kantojen j\u00e4tt\u00e4minen hakkuualoille olisi viisasta monimuotoisuuden kannalta, koska reilun vuoden vanhat kannot houkuttelevat edelleen kaarnakuoriaisia. Vanhenevat kannot toimivat siis kaarnakuoriaisten resurssina. Kantojen j\u00e4tt\u00e4minen hakkuualalle ei aiheuta pitk\u00e4aikaista uhkaa kaarnakuoriaisista mets\u00e4taloudelle, koska pahimpia tuholaislajeja tuli kannoille v\u00e4h\u00e4n.", "language": "fi", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2020-01-10T06:02:49Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2020-01-10T06:02:49Z (GMT).
