  2. 21. A network perspective on ecosystems, societies and natural resource management

    Author : Örjan Bodin; Jon Norberg; Steve Lansing; Stockholms universitet; []
    Keywords : network; seed dispersal; pollination; natural resource management; lemur catta; social networks; landscape fragmentation; Madagascar; East Africa; fisheries; resilience; co-management; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : This thesis employs a network perspective in studying ecosystems and natural resource management. It explores the structural characteristics of social and/or ecological networks and their implications on societies’ and ecosystems’ ability to adapt to change and to cope with disturbances while still maintaining essential functions and structures (i.

  4. 22. Artificial neural networks in models of specialization and sympatric speciation

    Author : Niclas Norrström; Högskolan i Skövde; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biology; Biologi; Naturvetenskap; Natural sciences;

    Abstract : This thesis deals with specialization and how it is linked to sympatric speciation. The trait driving specialization is a cue recognition trait modelled with artificial neural networks that exploiters use to discriminate beneficial resources from detrimental resources based on the signals of the resources.

  5. 23. Urban green networks : a socio-ecological framework for planning and design of green and blue spaces in Sweden and China

    Author : Na Xiu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Multi-disciplinary research is needed to address the issue of urban landscape fragmentation. Based on empirical and theoretical context analysis, a framework of network-based, socio-ecological methods and indicators that can be effectively applied by practitioners in different geographical locations was developed in this thesis.

  6. 24. Disturbances in food webs : Importance of species interactions from an ecological and evolutionary perspective

    Author : Anna Åkesson; Anna Eklöf; György Barabas; Vasilis Dakos; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Biodiversity loss is occurring globally at an unprecedented pace. This is not only followed by ethical concerns; it also affects all levels of an ecosystem, with wide-spread implications for ecosystem functioning, services and human well-being. READ MORE

  7. 25. Spatial distribution and conservation planning of seabed biological diversity

    Author : Genoveva Gonzalez-Mirelis; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spatial autocorrelation; ecological classifications; distribution modelling; biotopes; conservation planning; biodiversity surrogates; GIS; spatial ecology; benthos; fjord;

    Abstract : Knowledge of spatial patterns of biota has become a commodity for conservation practitioners and spatial ecologists alike. This type of information enables the identification of representative and unique biological features (at some nominal scale) which itself constitutes the application par excellence of knowledge of biodiversity distribution as it relates to the design of reserve networks and the realization of spatial planning.
