  1. 1. Tales of the flying earth: The effect of host flyways on the phylogeny of shorebird lice (Phthiraptera: Ischnocera)

    Författare :Daniel Gustafsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Parasite; Bird; Lice; Louse; Migration; Evolution; Ecology; Co-evolution; Lunaceps; Shorebirds; Carduiceps; Quadraceps; Revision; Phylogeny; Saemundssonia; Rallicolidae; Charadriiformes; Scolopacidae; Phthiraptera; Philopteridae; Ischnocera; Sandpiper; Flyways; Chewing Lice;

    Sammanfattning : On the wings, bodies, and heads of most birds there are lice. These lice spend their whole lives on their host, with the exception of the few lice that get the opportunity to transfer from one host to another, typically when the hosts come into physical contact with each other.

  3. 2. Pestens gåta : farsoter i det tidiga 1700-talets Skåne

    Författare :Bodil Persson; Historia; []
    Nyckelord :HUMANIORA; HUMANITIES; pestilential fevers; diagnosis; symptoms; pattern of distribution; demography; causes of death; burial records; epizootics; rats; rodents; lice; fleas; regional and local analysis; scurvy; epidemic typhus fever; measles; Plague; smallpox; plague vectors; Modern history up to circa 1800 ; Tidig modern historia till ca. 1800 ; Public health; epidemiology; Folkhälsa; epidemiologi;

    Sammanfattning : This study deals with Sweden’s last outbreak of the plague with focus on Skåne, where the epidemic raged for three years - from late autumn 1710 to late autumn 1713. This was a time of war, crop failures as well as other simultaneously occurring epidemics. LÄS MER

  4. 3. Studies of Genome Diversity in Bartonella Populations : A journey through cats, mice, men and lice

    Författare :Hillevi Lina Lindroos; Siv G. E. Andersson; Richard Birtles; Uppsala universitet; []
    Nyckelord :Biology; Bartonella; genome content; genome rearrangement; gene expression; phage; microarray; PFGE; MLST; Biologi;

    Sammanfattning : Bacteria of the genus Bartonella inhabit the red blood cells of many mammals, including humans, and are transmitted by blood-sucking arthropod vectors. Different species of Bartonella are associated with different mammalian host species, to which they have adapted and normally do not cause any symptoms. LÄS MER

  5. 4. Genetic Identification of Corkwing Wrasse Cleaner Fish Escaping from Norwegian Aquaculture

    Författare :Ellika Faust; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Conservation; Population structure; Genetics; Aquaculture; Hybridization; Corkwing wrasse; Cleaner fish; Sea lice; Symphodus melops; Escapee; Range expansion;

    Sammanfattning : The genetic impact of farmed fish escaping aquaculture is a highly debated issue. However, non-target species, such as cleaner fish that are used in fish farms to remove parasitic sea lice, are rarely considered. LÄS MER

  7. 5. Crossing barriers: Genetic consequences of translocating wild cleaner fish for aquaculture

    Författare :Ellika Faust; Göteborgs universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; conservation genetics; population genetics; aquaculture escapee; hybridisation; corkwing wrasse; lumpfish; cleaner fish translocation; sea lice; range expansion; fishery management;

    Sammanfattning : Several species of fish show a symbiotic cleaning behaviour, where they assist other species by feeding and removing dead skin or ectoparasites. Some of these cleaner fish species are used as a low-cost parasite control in salmon aquaculture, often considered to be more environmentally friendly than other delousing methods. LÄS MER
