  1. 1. Estimating historic ranges of extinct scavenging birds from North America during the late Pleistocene using co-occurrence data from the fossil record

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Melissa Miranda; [2023-06-30]
    Keywords : Scavenging birds; Vultures; Co-occurrence Data; Range Estimates; Spatial Autoregressive Models; Co-extinction;

    Abstract : The aim of my study was to estimate and compare the historic range of nine scavenging birds from North America that went jointly extinct with their mammalian megafaunal prey in the Late Pleistocene. Although the severity and timing of their co-extinction are strongly correlated, there has been little analytical support in providing estimates for the possible geographic distribution of scavenging birds prior to the extinction event.

  3. 2. Anti-Müllerskt hormon hos hanhund. Samband mellan avvikande testikelmorfologi, hormonets distribution i testikelvävnaden och koncentration i serum

    University essay from SLU/Dept. of Clinical Sciences

    Author : August Rooth; [2023]
    Keywords : Anti-Müllerskt hormon; AMH; Sertolicell; kryptorkism; immunohistokemi; testikelmorfologi; hanlig fertilitet hos hund;

    Abstract : Anti-Müllerskt hormon (AMH) är en av de första markörerna för hanlig könsutveckling i fosterstadiet hos däggdjur och fortsätter sedan att spela en stor roll för den hanliga fertiliteten. Hormonet produceras av testikelvävnadens Sertoliceller och bygger upp tubulära nätverk kallade seminiferösa tubuli, vari spermatogenesen äger rum. READ MORE

  4. 3. Dog owner knowledge and attitudes towards oral vaccination : a field study on canine rabies in Lao PDR

    Keywords : Neotropics; camera traps; terrestrial mammals; human presence; species richness; diversity index;

    Abstract : Human disturbance is becoming an ever-bigger threat to biodiversity across the globe and should continue to be a field of conservation priority. Urbanisation, research and tourism put unavoidable pressure on the surrounding flora and fauna, therefore we need to gain knowledge on how to reduce future harm. READ MORE
