    The distribution ranges and spatio-temporal patterns in the occurrence and activity of boreal bats are yet largely unknown due to their cryptic lifestyle and lack of suitable and efficient study methods. We approached the issue by establishing a permanent passive-acoustic sampling setup spanning the area of Finland to gain an understanding on how latitude affects bat species composition and activity patterns in northern Europe. The recorded bat calls were semi-automatically identified for three target taxa; Myotis spp., Eptesicus nilssonii or Pipistrellus nathusii and the seasonal activity patterns were modeled for each taxa across the seven sampling years (2015-2021). We found an increase in activity since 2015 for E. nilssonii and Myotis spp. For E. nilssonii and Myotis spp. we found significant latitude -dependent seasonal activity patterns, where seasonal variation in patterns appeared stronger in the north. Over the years, activity of P. nathusii increased during activity peak in June and late season but decreased in mid season. We found the passive-acoustic monitoring network to be an effective and cost-efficient method for gathering bat activity data to analyze spatio-temporal patterns. Long-term data on the composition and dynamics of bat communities facilitates better estimates of abundances and population trend directions for conservation purposes and predicting the effects of climate change

    In 2015 a long-term, nationwide tick and tick-borne pathogen (TBP) monitoring project was started by the Finnish Tick Project and the Finnish Research Station network (RESTAT), with the goal of producing temporally and geographically extensive data regarding exophilic ticks in Finland. In the current study, we present results from the first four years of this collaboration. Ticks were collected by cloth dragging from 11 research stations across Finland in May September 2015-2018 (2012-2018 in Seili). Collected ticks were screened for twelve different pathogens by qPCR: Borrelia afzelii, Borrelia garinii, Borrelia valaisiana, Borrelia burgdorferi sensu stricto, Borrelia miyamotoi, Babesia spp., Anaplasma phagocytophilum, Rickettsia spp., Candidatus Neoehrlichia mikurensis, Francisella tularensis, Bartonella spp. and tick-borne encephalitis virus (TBEV). Altogether 15 067 Ixodes ricinus and 46 Ixodes persulcatus were collected during 68 km of dragging. Field collections revealed different seasonal activity patterns for the two species. The activity of I. persulcatus adults (only one nymph detected) was unimodal, with activity only in May July, whereas Ixodes ricinus was active from May to September, with activity peaks in September (nymphs) or July August (adults). Overall, tick densities were higher during the latter years of the study. Borrelia burgdorferi sensu lato were the most common pathogens detected, with 48.9 +/- 8.4% (95% Cl) of adults and 25.3 +/- 4.4% of nymphs carrying the bacteria. No samples positive for F. tularensis, Bartonella or TBEV were detected. This collaboration project involving the extensive Finnish Research Station network has ensured enduring and spatially extensive, long-term tick data collection to the foreseeable future.Peer reviewe

    Seurantakäsikirja Suomen merenhoitosuunnitelman seurantaohjelmaan vuosille 2020–2026

    Get PDF
    Tämä merenhoidon seurantakäsikirja käsittää merenhoitosuunnitelman seurantaohjelman kuvauksen kokonaisuudessaan. Se päivittää vuoden 2014–2020 seurantaohjelman ja sitä sovelletaan vuoden 2020 heinäkuusta vuoden 2026 heinäkuuhun. Seurantaohjelma on osa merenhoidon suunnittelua, jota tehdään vesienhoidon ja merenhoidon järjestämisestä annetun lain (272/2011) ja merenhoidon järjestämisestä annetun valtioneuvoston asetuksen (980/2011) toteuttamiseksi. Tämä laki ja asetus on annettu meristrategiadirektiivin (Euroopan parlamentin ja neuvoston direktiivi 2008/56/EY yhteisön meriympäristöpolitiikan puitteista) kansallista toimeenpanoa varten. Suomessa meristrategiadirektiivin mukaista meristrategiaa kutsutaan merenhoitosuunnitelmaksi. Suomen seurantaohjelma koostuu 13:sta ohjelmasta, joiden alla on yhteensä 44 alaohjelmaa. Tähän päivitettyyn seurantaohjelmaan lisättiin kuusi uutta alaohjelmaa ja useita alaohjelmia muokattiin joko muuttuneiden vaatimusten, kehittyneempien menetelmien tai muuttuneen toimintaympäristön takia. Merenhoidon uusia vaatimuksia ovat meristrategiadirektiivin liitteen 3 päivitys (EU/2017/845), Euroopan komission päätös EU/2017/848 merivesien hyvän ekologisen tilan vertailuperusteista ja menetelmästandardeista sekä seurantaa ja arviointia varten tarkoitetut täsmennykset standardoiduista menetelmistä. Seurantakäsikirja koostuu kolmesta osasta: seurantaohjelman tausta, varsinainen seurantaohjelma, ja kolmas osa, joka käsittelee seurannan kehitystarpeita, kustannuksia ja riittävyyttä. Seurantaohjelma kattaa ekosysteemilähestymistavan mukaisesti erilaisia muuttujia, jotka kuvaavat toisaalta veden ominaisuuksia ja laatua ja toisaalta ekosysteemin osia ja niiden tilaa sekä niihin kohdistuvia ihmisestä johtuvia paineita. Seurannan alaohjelmissa on kuvattu mitattavat meriympäristön ominaisuudet tai paineet, niiden seurantatiheys, indikaattorit, joihin seurantatietoa käytetään, seurannalla kootun tiedon hallinta ja yhteydet meristrategiadirektiivin hyvän tilan laadullisiin kuvaajiin ja kriteereihin

    Handbok till övervakningsprogrammet för Finlands havsförvaltningsplan 2020–2026

    Get PDF
    Denna handbok är ett bakgrundsdokument till övervakningsprogrammet i Finlands havsförvaltningsplan och omfattar hela beskrivningen av programmet. Den uppdaterar övervakningsprogrammet 2014-2020 och tillämpar från juli 2020 till juli 2026. Övervakningsprogrammet är en del av havsvårdsplaneringen, som ingår i verkställandet av lagen om vattenvårds- och havsvårdsförvaltningen (272/2011) och statsrådets förordning om havsvårdsförvaltningen (980/2011). Med lagen och förordningen genomförs EU:s ramdirektiv om en marin strategi nationellt (Europaparlamentets och rådets direktiv 2008/56/EG om upprättande av en ram för gemenskapens åtgärder på havsmiljöpolitikens område, nedan MSD). I Finland kallas marina strategi för havsförvaltningsplan. Finlands övervakningsprogram består av 13 programhelheter med totalt 44 delprogram. Fyra nya delprogram lades till det uppdaterade övervakningsprogrammet, och flera delprogram reviderades antingen på grund av ändrade krav, mer avancerade metoder eller en förändrad operativmiljö. Nya krav under den andra havsförvaltningsperioden är uppdateringarna i bilaga 3 till ramdirektivet om en marin strategi (EU/2017/845) samt Europeiska kommissionens beslut EU/2017/848 om fastställande av kriterier och metodstandarder för god miljöstatus i marina vatten, specifikationer och standardiserade metoder för övervakning och bedömning. Övervakningshandboken består av tre delar: del I presenterar bakgrunden till övervakningsprogrammet, del II presenterar själva programmet och del III innehåller utvecklingsbehov, kostnader, övervakningens tillräcklighet och slutsatser. I enlighet med ekosystemansatsen omfattar övervakningsprogrammet olika variabler som dels beskriver vattnets egenskaper och kvalitet, dels ekosystemets delar och deras status samt mänsklig belastning på dessa. Handbokens presentationer av delprogrammen beskriver havsmiljöns egenskaper eller belastningar, övervakningsfrekvens, indikatorer för vilka övervakningsdata används, hantering av insamlade data och kopplingar till kvalitativa deskriptorer och kriterier för god miljöstatus enligt MSD
