2. 1. Changing Landscapes : An Environmental History of Chibuene, Southern Mozambique

   Author : Anneli Ekblom; Paul Sinclair; Louis Scott; João Morais; Uppsala universitet; []
   Keywords : HUMANIORA; HUMANITIES; Archaeology; environmental history; archaeology; archaeobotany; paleoecology; vegetation history; pollen analysis; environmental management; environmental insecurity; resource utilisation; landscape; paleclimatology; trade; oral tradition; Mozambique; Vilanculos; Arkeologi; Archaeology subjects; Arkeologiämnen;

   Abstract : This thesis analyses the dynamics of environmental change and its embeddedness in the long term interactions of social history and rainfall variability through the building of an environmental history of the Chibuene locality, the coastal plain of southern Mozambique, 5 km south of the town Vilanculos, from 400 AD to present day. Land-use practices over time are discussed on the basis of vegetation and land-use history based pollen analysis, charcoal influx and diatom analysis. READ MORE

4. 2. Insect Diversity in Changing Landscapes

   Author : Markus Franzén; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; växtparasitologi; Entomologi; plant parasitology; Zoology; Zoologi; Entomology; Ekologi; Ecology; butterfly; bee; dispersal; extinction; Djurekologi; Animal ecology;

   Abstract : During recent decades, concern about the loss of biodiversity has increased. To change this negative trend there is an urgent need for effective conservation measures and there are ample evidence that conservation of organisms without an understanding of their ecology and behaviour is impossible.

5. 3. Resilient Landscapes: socio-environmental dynamics in the Shashi-Limpopo Basin, southern Zimbabwe c. AD 800 to the present

   Author : Munyaradze Manyanga; Paul Sinclair; Alinah Segobye; Uppsala universitet; []
   Keywords : Archaeology; Shashi-Limpopo Basin; landscapes; perceptions; floodplains; wetlands; drylands; ecology; socio-political complexity; local knowledge; climate change; seasonal variability; resilience; southern Africa; Arkeologi; arkeologi; Archaeology;

   Abstract : The general perception today is that the Shashi-Limpopo Basin in southern Africa is hot and dry and not conducive to human habitation. Today there is no doubt that the Shashi-Limpopo Basin has been home to many communities throughout the pre-historical period. READ MORE

6. 4. Pollinators and Insect Pollination in Changing Agricultural Landscapes

   Author : Lina Herbertsson; Miljövetenskap; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; pollinators; pollination; agri-environment schemes; beekeeping; oilseed rape; sown flower strips; agri-environment measures;

   Abstract : Agricultural intensification and associated loss of semi-natural grasslands, has resulted in reduced landscape heterogeneity. A concomitant loss of forage and nest sites for pollinating insects has driven declines across several pollinator taxa. READ MORE

7. 5. Seed mobility and connectivity in changing rural landscapes

   Author : Alistair G. Auffret; Sara Cousins; Robin Pakeman; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biodiversity; Conservation; Functional connectivity; Historical ecology; Human-mediated dispersal; Invasive species; Landscape Ecology; Long-distance dispersal; Restoration; Seed bank; Seed dispersal; Seed rain; Structural connectivity; Physical Geography; naturgeografi;

   Abstract : The success or failure of many organisms to respond to the challenges of habitat destruction and a warming climate lies in the ability of plant species to disperse between isolated habitats or to migrate to new ranges. European semi-natural grasslands represent one of the world's most species-rich habitats at small scales, but agricultural intensification during the 20th century has meant that many plant species are left only on small fragments of former habitat.
