2. 1. Urban shades of green : Current patterns and future prospects of nature conservation in urban landscapes

   Author : Sara Borgström; Regina Lindborg; Sara Cousins; Thomas Elmqvist; Christer Nilsson; Stockholms universitet; []
   Keywords : urbanisation; nature conservation; urban planning; urban systems; nature reserves; Sweden; NATURAL SCIENCES; NATURVETENSKAP; naturresurshushållning; Natural Resources Management;

   Abstract : Urban nature provides local ecosystem services such as absorption of air pollutants, reduction of noise, and provision of places for recreation, and is therefore crucial to urban sustainable development. Nature conservation in cities is also part of the global effort to halt biodiversity decline. READ MORE

4. 2. Plant species diversity patterns in a Swedish rural landscape : effects of the past and consequences for the future

   Author : Sara A. O. Cousins; Roy Haines-Young; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : Plant species richness in rural landscapes is threatened as grassland management ceases or changes, and as many remaining semi-natural grasslands are becoming increasingly fragmented. This thesis is a study of plant species diversity in a rural landscape in south-eastern Sweden, and its relationship to management history and landscape pattern. READ MORE

5. 3. Distribution patterns of fleshy-fruited woody plants at local and regional scales

   Author : Matilda Arnell; Ove Eriksson; Johan Ehrlén; Sara A.O. Cousins; Angela Moles; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fleshy fruits; woody plants; dispersal; distribution patterns; range filling; dispersal limitation; historical land use; spatial associations; point-pattern analysis; recruitment; reproduction; pollination; fruit set; fruit-removal; Daphne mezereum; Plant Ecology; växtekologi;

   Abstract : Fleshy-fruited woody plants share a long history with humans, providing us with food and wood material. Because of this relation, we have actively moved some of these plants across landscapes and continents. READ MORE

6. 4. 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.

7. 5. The role of past and present management in the seed dispersal of grassland plants in the rural landscape

   Author : Alistair Auffret; Sara Cousins; Per Milberg; Stockholms universitet; []
   Keywords : ;

   Abstract : The destruction and fragmentation of semi-natural grasslands due toagricultural industrialisation during the past 150 years has had seriousconsequences for biodiversity in the rural landscape. Currently, plantcommunities are usually better explained by historical than by presentday landscape configurations, and the ability for plant species todisperse in space and in time, within and between remaining habitatfragments or to restoration sites will be an important factor in thefuture diversity in the landscape.
