2. 6. Fragmented landscapes : Assessment and communication of landscape connectivity in human-dominated landscapes

   Author : Arvid Bergsten; Örjan Bodin; Bo Ebenman; Stockholms universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fragmentation; Connectivity; Network; Spatial; Landscape; Dispersal; Planning; Social-Ecological; Scale; IIC; STS; naturresurshushållning; Natural Resources Management;

   Abstract : This licentiate thesis summarizes the first half of my PhD on the theme of management of fragmented landscapes. The thesis applies – and reflects on the use of – network analysis of connectivity in relation to landscape planning. READ MORE

4. 7. Genetic connectivity of fish in the Western Indian Ocean

   Author : Oskar Henriksson; Mats Grahn; Anders Angebjörn; Filip Volckaert; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; population genetics; indian ocean; siganus sutor; valamugil buchanani; scarus ghobban; connectivity; aflp; mtDNA; d-loop; CO1; zoologisk ekologi; Animal Ecology;

   Abstract : An almost unbroken fringing reef runs along the east coast of Africa, the lagoon inside the reef is the foundation of almost all artisanal fisheries. It is a low-tech fishery conducted by many people. Some areas can have up to 19 fishermen per square kilometer. READ MORE

5. 8. Re-establishment of connectivity for fish populations in regulated rivers

   Author : Olle Calles; Larry Greenberg; Lars Nyberg; David Scruton; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Attraction efficiency; Connectivity; Flow regime; Hyporheic water quality; Nature-like fishway; Passage efficiency; Regulated river; Remedial measures; Salmo trutta; Biology; Biologi; Biology; Biologi;

   Abstract : The hydropower industry has altered connectivity in many rivers during the last century. Many fish species depend on both an intact longitudinal connectivity to be able to migrate between spawning, feeding and winter habitats, and vertical connectivity for development and survival of incubating embryos and larvae in the gravel.

6. 9. Fish in the coastal seascape : exploring ecological processes and connectivity for conservation of temperate fish communities

   Author : Thomas Staveley; Martin Gullström; Mats Björk; Regina Lindborg; Emma Jackson; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; seascape ecology; landscape ecology; seagrass; marine habitats; fish; spatial analysis; connectivity; conservation; Sweden; temperate; Marine Ecology; marin ekologi;

   Abstract : The need to understand patterns and processes in the marine environment has never been so profound as today, particularly as anthropogenic pressures upon coastal regions are drastically affecting habitats and species across a vast range. One approach to further understand these patterns and processes is through the use of seascape ecology methods. READ MORE

7. 10. The use of highway crossings to maintain landscape connectivity for moose and roe deer

   Author : Mattias Olsson; Per Widén; Anthony Clevenger; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; wildlife crossings; Barrier effect; habitat selection; ecoduct; moose; roe deer; connectivity; conservation; overpass; underpass; highway; exclusion fencing; Biology; Biologi; Biology; Biologi;

   Abstract : Increasingly wildlife managers and land managers are challenged to maintain the viability and connectivity among large mammal populations. Thus, it is important that effective highway crossings are identified and optimized with respect to construction cost, facilitation of ungulate movements, and ability to reduce wildlife-vehicle collisions.
