  1. 1. Saproxylic beetles in Populus tremula fauna depots - how do you construct the best depot?

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Simon Selberg; [2019]
    Keywords : aspen; populus; tremula; saproxylic; beetle; fauna; depot; species; richness; abundance; diversity; cwd; course; woody; debris; forest; asp; populus; tremula; vedlevande; skalbagge; fauna; depå; art; mångfald; diversitet; död; ved; cwd; skog;

    Abstract : The biodiversity of saproxylic organisms and in the case of this study, saproxylic beetles, is dependent on the amount and quality of course woody debris (CWD) in the environment. Over the past decades the quantity of CWD in Swedish forests has increased, yet the quality has decreased, forests are managed and exploited, and old-growth forests are rarer. READ MORE

  2. 2. Urban sandy habitats : designing through nature conservation methods

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

    Author : Boglárka Szilassy; [2019]
    Keywords : sand; cultural landscape; sandy habitat; management; restoration; design; Tempelhofer Feld; prototype; native; grazing;

    Abstract : Sandy habitats carry an extreme diversity. They occur in many various types and forms from coast to inland. Also, there are landscape types that occur in sandy environments but are not exclusively sandy habitats. But what we can say about all for sure, is that they need disturbance to survive. READ MORE

  3. 3. A descriptive study of the role of maternal behavior in the survival of Markhor (Capra falconeri) kids

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Daniel Asif; [2019]
    Keywords : Markhors; maternal behavior;

    Abstract : In a herd of captive Markhors, observations were made to investigate the elements of maternal behavior, interactions of mothers with their kids, visitor’s effect and welfare. Females isolated themselves from other conspecifics before parturition and selected a parturition site in the elevated part of the enclosure. READ MORE

  4. 4. How does white rhino respond to fires during dry season?

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Tim Herkenrath; [2019]
    Keywords : white rhino; post-fire regrowth; habitat selection; African grazers; megaherbivore;

    Abstract : The white rhino is a megaherbivore grazer that favours the short and nutrient-rich grass on grazing lawns. Since regrowth on lawns requires a certain amount of rainfall, the usage of this food resource is limited to the wet season. During the dry season, white rhinos are able to feed on senescent tall grass. READ MORE

  5. 5. Importance of fish community structure, nutrients and browning for shallow lake ecosystem dynamics : A modelling perspective

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Ylva Karlberg; [2019]
    Keywords : biological modelling; bowning; food webs; trophic interactions; top-down and bottom-up control; nutrients; light; shallow lake; biologisk modellering; brunifiering; födovävar; trofiska interaktioner; näring; ljus; grund sjö;

    Abstract : In a changing climate, it is increasingly important to be able to model environmental effects on food webs, and to do that, one must have appropriate dynamic models. I present a shallow lake ecosystem model where producers, grazers, carnivores, piscivores, and detritivores are coupled through resource (light, nutrients and detritus) fluxes between the benthic and pelagic habitats and through carnivore life history events (ontogenetic habitat and diet shifts).
