    Abstract : 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.

  3. 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

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Most Shova Banu; [2023]
    Keywords : ;

    Abstract : 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. READ MORE

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

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Henrik Johansen; [2021]

  6. 5. The direct and indirect relation between ungulates on small mammals

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Michael Wentzel; [2020]
    Keywords : small mammals; ungulates; vegetation cover; food competition; path analysis; direct; indirect; canopy cover; Sweden;

    Abstract : Ungulates are increasing in Europe, including Sweden and can cause changes to forest structure and forest-dwelling animals. This study is focused on the relation between various ungulate species and small mammal abundance in Swedish forests, through the alteration of ground vegetation cover and directly through food competition.
