Are small protected habitat patches within boreal production forests effective in conserving species richness, abundance and community composition? :…
2021
Abstract Background In boreal zone forest management is changing and degrading forest habitats, which has caused declines in biodiversity. To mitigate these harmful effects in production forests, small-scale habitats with high biodiversity values have been protected within them. These habitats include woodland key habitats, and other small habitat patches protected by voluntary conservation actions. In this systematic review we synthesize the evidence on the value of small protected habitat patches (SPHP) within production forest landscapes for biodiversity. Review question: Are small protected habitat patches within boreal production forests effective in conserving species richness, abunda…

Morphological traits predict host-tree specialization in wood-inhabiting fungal communities
2020
Tree species is one of the most important determinants of wood-inhabiting fungal community composition, yet its relationship with fungal reproductive and dispersal traits remains poorly understood. We studied fungal communities (total of 657 species) inhabiting broadleaved and coniferous dead wood (total of 192 logs) in 12 semi-natural boreal forests. We utilized a trait-based hierarchical joint species distribution model to examine how the relationship between dead wood quality and species occurrence correlates with reproductive and dispersal morphological traits. Broadleaved trees had higher species richness than conifers, due to discomycetoids and pyrenomycetoids specializing in them. Re…
Sympatric Ixodes-tick species: pattern of distribution and pathogen transmission within wild rodent populations
2018
AbstractThe generalist tick Ixodes ricinus is the most important vector for tick-borne pathogens (TBP), including Borrelia burgdorferi sensu lato, in Europe. However, the involvement of other sympatric Ixodes ticks, such as the specialist vole tick I. trianguliceps, in the enzootic circulations of TBP remains unclear. We studied the distribution of I. ricinus and I. trianguliceps in Central Finland and estimated the TBP infection likelihood in the most common rodent host in relation with the abundance of the two tick species. Ixodes trianguliceps was encountered in all 16 study sites whereas I. ricinus was frequently observed only at a quarter of the study sites. The abundance of I. ricinus…
The conservation potential of brook-side key habitats in managed boreal forests
2011
Today, maintaining biodiversity is included in the targets of boreal forest management. A widespread approach in northern Europe is to identify and preserve woodland key habitats within managed forests. Woodland key habitats are expected to be patches that host populations of threatened and declining species, and the preservation of these patches is assumed to enable the persistence of the focal species in the landscape. In Finland, the criteria for selecting woodland key habitats are defined in the Finnish Forest Act, and the selection has been done by forest practitioners. Our objective was to determine whether the surroundings of boreal brooks and rivulets qualified as key habitats are t…
ENDEMIC HANTAVIRUS INFECTION IMPAIRS THE WINTER SURVIVAL OF ITS RODENT HOST
2007
The influence of pathogens on host fitness is one of the key questions in infection ecology. Hantaviruses have coevolved with their hosts and are generally thought to have little or no effect on host survival or reproduction. We examined the effect of Puumala virus (PUUV) infection on the winter survival of bank voles (Myodes glareolus), the host of this virus. The data were collected by monitoring 22 islands over three consecutive winters (a total of 55 island populations) in an endemic area of central Finland. We show that PUUV infected bank voles had a significantly lower overwinter survival probability than antibody negative bank voles. Antibody negative female bank voles from low-densi…

Hyötyä ja kaunistusta : Keski-Suomen Emäntäkoulun historiallinen puutarha
2014
Tämä pro gradu -tutkielma käsittelee Keski-Suomen Emäntäkoulun historiallista puutarhaa ja puistomaista ympäristöä. Emäntäkoulu perustettiin Mankolan tilalle lähelle Jyväskylän keskustaa, ja maataloushallituksen arkkitehti Jalmari Peltosen suunnittelema koulurakennus valmistui vuonna 1932. Koulussa opiskeltiin monipuolisia talouden- ja kodinhoidon töitä, joiden katsottiin kuluvan maalaistalon emännälle. Emäntäkouluun kuului laaja koulupuutarha, jolla oli tärkeä asema opetuksessa ja sisäoppilaitoksen ruokatalouden ylläpitämisessä. Emäntäkoulun käyneiden naisten kautta kotipuutarhat ja puutarhaviljelys levisivät maaseudulle. Mankolan alue, johon tutkimuskohde sisältyy, on suojeltu valtakunnal…
Suomalainen moderni puuasuntorakentaminen 1990 - ja 2000 -lukujen vaihteessa : tapausesimerkkinä Niiralan Kulma Oy:n modernit puuvuokratalot Kuopiossa
2010
Tutkielman näkökulma kohdistuu rakennettuun ympäristöön. Tutkielmassa selvitetään 1990-luvun lopun suomalaista modernia puuasuntorakentamista. Tapausesimerkkinä työssä toimii kuopiolaisen kaupungin vuokrataloyhtiö Niiralan Kulma Oy:n moderni puinen asuntorakentaminen Kuopion Petosen kaupunginosassa. Työssä käsiteltävät esimerkkirakennuskohteet ovat Kortekatu 5, Petosenkuja 1 eli Nurmirannantie ja Torpankatu 2. Tutkimuskohde, Niiralan Kulman moderni puurakentaminen sijoitetaan osaksi suomalaisen modernin puurakentamisen kontekstia, Niiralan Kulma Oy:n rakennustoimintaa sekä Petosen kaupunginosan kehitystä. Niiralan Kulman puisesta rakennustoiminnasta pyritään havainnoimaan niitä piirteitä ja…
