  1. 1. COMPARING THE COMPOSITION OF SAPROXYLIC BEETLE FAUNA ON OLD HOLLOW OAKS BETWEEN TWO TIME PERIODS

    University essay from Linköpings universitet/Biologi

    Author : Chipango Kamboyi; [2019]
    Keywords : Saproxylic beetles; Guilds; Species composition; Canopy Cover; Forest Regrowth; Trunk Circumference; Cavity size. Species turnover;

    Abstract : Oak habitats are rich in saproxylic species, but the habitat is declining with loss of diversity due to encroachment which decrease the vitality of oaks. The present explorative study compared results from a study conducted in 1994, with present species communities to observe if there has been change in species composition and what factors that can explain species diversity and composition.

  2. 2. The Importance of Trait Mediated Indirect Interactions in Marine Ecosystems

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

    Author : Carlos Valbuena-Gonzalo; [2019]
    Keywords : TMII; BMII; behaviour; predation; non-comsuptive effect;

    Abstract : The importance of Trait Mediated Indirect Interactions (TMII) is increasingly being recognized. TMII are interactions between two species via a change in trait (behavioural, morphological, but not numerical) over a third one, which together cause ecological dynamics. READ MORE

  3. 3. Effect of restoration and surrounding grassland proportion on the dung beetle metapopulation abundance in the fragmented semi-natural grasslands : dung beetles in restored semi-natural grasslands

    University essay from SLU/Dept. of Ecology

    Author : Vivek Babu; [2018]
    Keywords : dung beetle; grassland proportion; restoration; Aphodius; Geotrupes; abundance; semi-natural grassland; Scarabaeidae; metapopulation; habitat fragmentation; landscape ecology;

    Abstract : The importance of landscape composition surrounding the local habitats is increasingly recognized, especially with goal of enhancing the understanding about its role in various conservation frameworks. The dung beetles which depend on human mediated ephemeral resources (Dung from domestic animal) gives a valuable opportunity for understanding landscape moderated effects of both the landscape structure as well as sensitive grazing management on the local populations of semi-natural grasslands in Sweden.

  4. 4. EU tree density limits in wooded pastures and their effects on bat populations within traditional agricultural landscapes

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Heather Wood; [2016]
    Keywords : ;

    Abstract : The European Union’s Common Agricultural Policy (CAP) recommends subsidies are only granted for wooded pastures with less than 100 trees per hectare. This arbitrary guidance exists despite these habitats being among the most biodiverse in rural Europe. READ MORE

  5. 5. Do riparian plant functional groups from northern Sweden respond differently to hydropeaking?

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

    Author : María Garteizgogeascoa; [2016]
    Keywords : Hydropeaking; riparian vegetation; seedlings;

    Abstract : In recent years, global warming awareness has resulted in an increased demand for clean sources of energy such as hydropower. As a consequence, its impact on riparian vegetation must be studied. In this research, I aimed to assess how different functional riparian groups from northern Sweden respond to hydropeaking (i.e. READ MORE
