  1. 1. Förutsättningar och möjligheter för växtgestaltning med luftrenande effekt i tunnelbanan

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Sofia Lekander; [2019]
    Keywords : luftrenande växter; tunnelbanemiljö; underjordisk design; luftkvalitet; stationsdesign;

    Abstract : Växtgestaltning är ett holistiskt tillvägagångssätt för att skapa platsbildning och även utnyttja växters och utformningars gentjänster. Uppsatsen tillämpar disciplinen på tunnelbanestationer med huvudsakligt syfte att minska luftföroreningar. Både växtval och stationens utformning visar sig kunna bidra till förbättrad luftkvalitet.

  3. 2. 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.

  4. 3. Temporal spawning divergence in European whitefish (Coregonus lavaretus) : The first steps towards reproductive isolation in young populations (70-171 years)

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Petter Johansson; [2017]
    Keywords : Population divergence; Coregonus lavaretus; spawning whitefish; reproductive isolation; young populations;

    Abstract : A critical step in ecological speciation is the development of reproductive isolation. The processes leading up to reproductive isolation are difficult to study since they often occur over very long time periods. READ MORE

  5. 4. Morphological differences in the apposition eyes found in different species of stingless bees (Meliponnini: Apidae: Hymenpotera) with X-ray microtomography

    University essay from Lunds universitet/Examensarbeten i biologi

    Author : Viktor Håkansson; [2016]
    Keywords : Biology and Life Sciences;

    Abstract : As the most diverse group of animals in the world with more than a million describes species, insects varies in many aspects of their ecology. Bees are insects that can be found in many different habitats across the world. READ MORE

  6. 5. Adaptive trait utility in the feeding apparatus of European whitefish (Coregonus lavaretus) : Relationships between feeding morphology and maximum and minimum prey size in the diet of whitefish

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Emma Andersson; [2015]
    Keywords : trait utility; gill rakers; adaptive radiation; morphological adaptation; feeding niche;

    Abstract : Whitefish (Coregonus lavaretus) populations diverge into morphs that differ in body size along a benthic-limnetic axis and throughout the depth of the water column. This process is assumedly initiated by the presence of northern pike (Esox lucius) and is followed by morphological adaptations to available food resources. READ MORE
