  1. 1. Påverkan av ett fysiskt träningsprogram på hull, muskelmassa och kroppsvikt hos hund : ”Body condition score” och morfometriska mått för bröst-, buk- och låromfång

    University essay from SLU/Dept. of Clinical Sciences

    Author : Johanna Berndtsson; Emilia Deimel; [2022]
    Keywords : BCS; bröstomfång; bukomfång; hullbedömning; låromfång; morfometriska kvoter; morfometriska mått; övervikt;

    Abstract : Det finns begränsat med forskning om hur fysisk träning påverkar hundar och såvitt kandidatarbetets författare känner till finns detingen tidigare studie som undersökt hur “body condition score” (BCS), kroppsvikt, bröst- och buk- och låromfång förhåller sig till varandra hos hundar före och efter ett fysiskt träningsprogram. Syftet med detta kandidatarbete var därför att undersöka hur ett träningsprogram påverkar BCS, kroppsvikt och olika morfometriska mått hos hund. READ MORE

  3. 2. Wing Shape Variation In A Damselfly: Effects Of Range Margins And Latitude

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Desirée Kristensson; [2021]
    Keywords : damselfly; evolution; distribution; sexual selection; range margins; Lestes sponsa; geometric morphometric;

    Abstract : An optimal wing shape is necessary for the survival of winged insects since it enables different survival strategies and is expected to vary between environments due to different selection pressures. However, few studies have explored wing shape variation across the whole range of a species. READ MORE

  4. 3. Time Constraint and Genetic (Phenotypic) Variation in Wing Shape in a Damselfly Along a Latitudinal Gradient

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Meagan Tunon; [2020]
    Keywords : Damselfly; time constraint; wing shape; morphology; climate change;

    Abstract : This degree project examined the effect of time constraint on wing shape and phenotypic variation in wing shape along a latitudinal gradient in the damselfly species Lestes sponsa. Fore and hind wings from individuals originating from three different latitudes: North (66°N), Central (59°N) and South (54°N) Europe were treated with their native temperature and photoperiod.

  5. 4. Automatic landmark identification in digital images of Drosophila wings for improved morphometric analysis

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Sebastian Bas Kanå; [2019]
    Keywords : ;

    Abstract : A considerable number of morphometric studies which are performed nowadays with fly wing images require manual annotation of landmarks or key-points. This work is tedious and time consuming for researchers. This is why there is interest in automating the process and therefore several approaches for this purpose have been developed. READ MORE

  6. 5. Morphological variation in the hadrosauroid dentary

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Fredrik Söderblom; [2017]
    Keywords : Hadrosauroidea; dentary; morphometric; heterochrony; peramorphosis; mastication; Hadrosauroidea; dentärben; morfometrisk; heterokroni; peramorfos; tugga;

    Abstract : The near global success reached by hadrosaurid dinosaurs during the Cretaceous has been attributed to their ability to masticate (chew). This behavior is more commonly recognized as a mammalian adaptation and, as a result, its occurrence in a non-mammalian lineage should be accompanied with several evolutionary modifications associated with food collection and processing.
