    Sammanfattning : Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall Abstract Unintentional by-catch in fishing gear is a significant cause of mortality of harbour porpoises in UK waters. Understanding the spatial distribution of harbour porpoises at fine scales and how this changes over time is essential when trying to understand where these lethal interactions might occur. LÄS MER

  2. 2. Investigation of the interaction of A-MYB and TCFL5 on pachytene PIWI-interacting RNA genes in two sub-species of mice, mus musculus musculus and mus musculus castaneus

    Master-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Most Shova Banu; [2023]
    Nyckelord :;

    Sammanfattning : Spermatogenesis is a complex process that involves the production of sperm cells from germ cells in order to transmit genetic information to progeny. The PIWI-interacting RNA (piRNA) is a non-coding small silencing RNA that guides the PIWI protein to silence target transposon transcripts to regulate the production of germ cells. LÄS MER

  3. 3. Mikroplast i tumlare - Metodutveckling i sökandet efter mikroplaster i tarminnehåll från tumlare

    Kandidat-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Thea Eriksson; [2021]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : An ever-growing problem is the increasing amount of microplastics in the sea and how they affect marine organisms. Microplastics are small pieces of plastic that are between 0.1 - 500 micrometres. They are divided into primary and secondary microplastics. LÄS MER

  4. 4. The role of diseases in mass mortality of wood lemmings (Myopus schisticolor)

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Henrik Johansen; [2021]
    Nyckelord :wood lemming; Myopus schisticolor; disease; virus; pathogens; mass mortality; orthohantavirus; pan-orthohantavirus; somatic index; spleen index;

    Sammanfattning : Like many other rodent species, the wood lemming (Myopus schisticolor) exhibits cycles with large population peaks but unlike most other European rodents, these peaks are frequently followed by mass mortality. It is largely unknown what pathogens wood lemmings carry and if pathogens could affect their population dynamics. LÄS MER

  5. 5. Den artrika stadsparken : ekosystembaserad gestaltning med natur- och kulturlandskapet som förebild

    Master-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Martina Ulinder; [2021]
    Nyckelord :ekosystem; kulturlandskap; ekosystemtjänster; landskapsarkitektur; växtteknik; nöthagen; Nyköping; biologisk mångfald; artrik;

    Sammanfattning : Vi lever i en tid där människans relation till naturen förändrats radikalt under de senaste århundradena. I tusentals år har vår existens präglats av ett liv i direkt kontakt med naturen, där samspelet mellan naturliga processer och människans bruk varit uppenbart och direkt avgörande för hennes överlevnad.
