  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.

  4. 3. Habitat types in relation to bird diversity in boreal forestry landscapes in Sweden

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Engla Grönvall; [2023]
    Keywords : Biodiversty; Forestry; Bird diversity; Habitat types; Species Richness;

    Abstract : Boreal forests in Europe are intensively managed for timber and pulp production, resulting in decreased biodiversity, and in the long-term leading to a reduced number of functioning ecosystem services. To develop a more sustainable forest management it is important to investigate what features and habitat types are needed to preserve a high diversity of species within the forestry landscapes.

  6. 5. Villaträdgårdarnas bidrag till biologisk mångfald i Malmö : nuläge och framtida möjligheter, med Rostorp som exempel

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Johanna Kristina Lassvik; [2022]
    Keywords : grönyta; trädgårdar; miljömål; Malmö Stad; Rostorp;

    Abstract : Malmös villaträdgårdar kan få en viktig roll för en bibehållen och/eller ökad biologisk mångfald när staden förtätas i framtiden och mosaiken av små grönområden riskerar att försvinna. Rostorps egnahemsområde i Malmö har en koncentrerad artrikedom av växter på relativt små ytor som man inte ofta stöter på ens i kommunala parker i Malmö. READ MORE
