Expansion of rDNA and pericentromere satellite repeats in the genomes of bank voles Myodes glareolus exposed to environmental radionuclides
2021
Abstract Altered copy number of certain highly repetitive regions of the genome, such as satellite DNA within heterochromatin and ribosomal RNA loci (rDNA), is hypothesized to help safeguard the genome against damage derived from external stressors. We quantified copy number of the 18S rDNA and a pericentromeric satellite DNA (Msat‐160) in bank voles (Myodes glareolus) inhabiting the Chernobyl Exclusion Zone (CEZ), an area that is contaminated by radionuclides and where organisms are exposed to elevated levels of ionizing radiation. We found a significant increase in 18S rDNA and Msat‐160 content in the genomes of bank voles from contaminated locations within the CEZ compared with animals f…
Inspired by nature: Fiber networks functionalized with tannic acid and condensed tannin-rich extracts of Norway spruce bark show antimicrobial effica…
2023
This study demonstrated the antibacterial and antiviral potential of condensed tannins and tannic acid when incorporated into fiber networks tested for functional material purposes. Condensed tannins were extracted from industrial bark of Norway spruce by using pressurized hot water extraction (PHWE), followed by purification of extracts by using XADHP7 treatment to obtain sugar-free extract. The chemical composition of the extracts was analyzed by using HPLC, GC‒MS and UHPLC after thiolytic degradation. The test matrices, i.e., lignocellulosic handsheets, were produced and impregnated with tannin-rich extracts, and tannic acid was used as a commercial reference. The antibacterial and antiv…
Vēlā dzelzs laikmeta un viduslaiku sākuma posma skeletkapi Ziemeļkurzemē (9.-14.gs.)
2015
Bakalaura darba mērķis ir izvērtēt un analizēt apbedīšanas tradīcijas un apbedīto etnisko piederību 14 arheoloģiski pētītos vai apzinātos Ziemeļkurzemes kapulaukos ar skeletapbedījumiem- no tiem 11 ar vēlo dzelzs laikmetu datētos (11.-12.gs.) Baltijas somu un trijos ar viduslaiku sākumposmu datētos (13.-14.gs.) kapulaukos. Pētījuma gaitā tiek apstiprināta tēze, ka vismaz astoņos kapulaukos - Tukuma Jaunajā tirgus laukumā, Mežītē, Lībagu Kalneniekos, Laidzes Pēčos, Matkules Lanksēdē, Virbu Zunnās, Lībagu Ķīļos, un Lībagu Lejaslāčos, domājams, ir apbedīti vendi laikposmā no 11.gs. beigām līdz 12.gs. Trīs kapulaukos apbedīto etnisko piederību ar līdzšinējām liecībām konstatēt nav iespējams, be…
Kestävä metsätalous edellyttää talouden mittareiden laajentamista, kansalaisten ja metsänomistajien tahdon kuulemista sekä kestävyyden luontoperustan…
2021
Vallitseva metsänhoidon tapa on taloudellisesti lyhytnäköinen, ekologisesti kestämätön ja kansan enemmistön tahdon vastainen. Näin ei kuitenkaan tarvitse olla,vaan taloudelliset ja ekologiset tavoitteet sekä kansalaisten toiveet on mahdollista sovittaa yhteen, toteaa Mikko Mönkkönen, soveltavan ekologian professori. nonPeerReviewed
Are woodland key habitats biodiversity hotspots in boreal forests?
2011
Background: The concept of Woodland Key Habitats (WKH, small-scaled presumed hotspots of biodiversity) has become an essential component of forest management in Fennoscandian and Baltic countries. There have been debates over the importance of WKHs in relation to production forests, and several research projects have focused on differences in biodiversity between the two. Results have been contradictory, and thus there is a need to summarize and clarify the existing knowledge. - Objectives: Our objective was to summarize knowledge on comparisons of several biodiversity qualities between WKHs and production forests in relevant countries i.e. the countries where WKH concept has been implement…
Estimating Tree Health Decline Caused by Ips typographus L. from UAS RGB Images Using a Deep One-Stage Object Detection Neural Network
2022
Various biotic and abiotic stresses are causing decline in forest health globally. Presently, one of the major biotic stress agents in Europe is the European spruce bark beetle (Ips typographus L.) which is increasingly causing widespread tree mortality in northern latitudes as a consequence of the warming climate. Remote sensing using unoccupied aerial systems (UAS) together with evolving machine learning techniques provide a powerful tool for fast-response monitoring of forest health. The aim of this study was to investigate the performance of a deep one-stage object detection neural network in the detection of damage by I. typographus in Norway spruce trees using UAS RGB images. A Scaled…
