  1. 16. Land use changes and its consequences on moose habitat

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Ida Olofsson; [2017]
    Nyckelord :land use change; habitat selection; moose calf mortality; Öland; agricultural landscapes;

    Sammanfattning : Human land use can reduce the amount and quality of wildlife habitats. During recent years, a high moose calf summer mortality have been discovered on Öland. Öland is a predator-free island in Sweden that is dominated by agriculture and presence of humans and grazing livestock. LÄS MER

  3. 17. Uppföljning av utfört arbete i kantzon mot vattendrag i gallringar

    Kandidat-uppsats, SLU/School for Forest Management

    Författare :Jenny Eriksson; [2016]
    Nyckelord :naturhänsyn; vattenvård; avverkning;

    Sammanfattning : Damage of ground or water conditions due to logging operations is a subject of discussion within Swedish forestry. Heavy logging machinery is sometimes entering water areas, delicate habitats and endangered species causing damage to these habitats. LÄS MER

    Nyckelord :warthog; phacochoerus africanus; kichwa tembo;

    Sammanfattning : The common warthog (Phacochoerus africanus) is common over all of Africa’s savannah grassland. The females live in small family groups with their offspring and the males alone or in bachelor groups. The warthog is a grazer but can also eat fruits and roots.

  5. 19. Measurement of Abundance and Activity of the Northern bat Eptesicus nilssonii, in Forests and Edge habitats in Sweden - Tools for Conservation Planning

    Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Björn Palmqvist; [2014]
    Nyckelord :northern bat; Eptesicus nilssonii; abundance measurements; bat ecology;

    Sammanfattning : Good estimations of habitat preference and activity of bats in different habitats are of great importance when planning for conservation or assessing consequences of exploitation. The objective of this study was to compare two different methods for abundance estimation: line- transects (active taxation) and point taxation by autobox recordings (passive taxation), and correlation analyses were made between data from these methods.

  7. 20. Differentiation of dispersive traits under a fluctuating range distribution in Asellus aquaticus

    Kandidat-uppsats, Linköpings universitet/Biologi; Linköpings universitet/Tekniska högskolan

    Författare :Martin Brengdahl; [2014]
    Nyckelord :Asellus aquaticus; Dispersion; Dispersive traits; Habitats; Isopoda; Lake Tåkern; Spatial selection; Vegetation;

    Sammanfattning : Knowledge about dispersion is of utmost importance for understanding populations’ reaction to changes in the environment. Expansion of a population range brings with it both spatial sorting and over time, spatial selection. This means that dispersion rates increases over time at the expanding edge. LÄS MER
