  1. 1. Classification and structural connectivity of urban vegetation : A comparative study using different datasets

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Malin Lundberg; [2018]
    Keywords : Connectedness; effective mesh size; fragmentation; landscape metrics;

    Abstract : Urban greenspace has an important role in supporting biodiversity and providing structural and functional connectivity between natural habitats. However, the mapping of vegetation in urban areas presents challenges, as urban vegetation is highly fragmented and heterogeneous. READ MORE

  2. 2. Ecologically viable population sizes: Determining factors

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Stefan Sellman; [2010]
    Keywords : assembly model; ecologically effective populations; extinction; keystone species; MEVP; MVP; species interactions;

    Abstract : The minimum ecologically viable population size (MEVP) of a species describes the minimum size at which the species itself or another species in the same ecosystem goes extinct as a result of the loss of inter-specific interactions. The MEVP shows a good potential for use as a tool for exploring the mechanisms behind species extinctions, but presently only a small amount of research has been done that takes advantage of this.

  3. 3. Minimum Ecologically Viable Populations : Risk assessment from a multispecies perspective

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Torbjörn Säterberg; [2009]
    Keywords : Ecological effective population size; extinction; minimum viable population; multispecies modeling; population viability analysis;

    Abstract : The extinction risk of threatened species has traditionally been assessed by the use of tools of Population Viability Analysis (PVA). Species interactions, however, have seldom been accounted for in PVA:s. The omission of species interactions in risk assessments may further lead to serious mistakes when setting target sizes of populations. READ MORE
