2. 1. Application of the Fluoresecence Lidar Techniques in the Architectural Heritage

   Author : Jenny Hällström; Bebyggelsevård; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; architectural heritage; stone; brick; conservation; restoration; case studies; building investigation; lidar; fluorescence; laser; masonry;

   Abstract : The primary aim of the research project is to analyse the potential for the application of lidar and fluorescence techniques in building investigation, and also to establish a scientific remote-sensing method for surveying and analysing the historical facade that is non-destructive and can be used in-situ. The fluorescence lidar method uses point-monitoring and scanning of areas that can provide multispectral images in order to identify materials, biodeteriogens and other substances not visible to the human eye.

4. 2. Non-Invasive Monitoring of Architectural Heritage

   Author : Jenny Hällström; Bebyggelsevård; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; remote sensing; lidar; laser-induced fluorescence; documentation; hyperspectral; non invasive; non destructive; sustainable maintenance; conservation planning; monitoring; Coliseum; architectural conservation; restoration; Övedskloster; deterioration; Lateran Baptistery; stone; brick; thematic mapping; in situ; imaging; biodeteriogens;

   Abstract : The on-site documentation and examination of architectural heritage has presented challenges for traditional analysis methods in the form of, among other things, large complex structures, sites and environmental conditions. In recent years there has been growing interest in assessing progressing deterioration processes and material analysis, with an emphasis on sustainable conservation and maintenance planning.

5. 3. Predation and shorebirds: predation management, habitat effects and public opinions

   Author : Daniel Isaksson; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Conservation; waders; predation; coastal pastures; redshank; lapwing; attitudes; human dimensions;

   Abstract : Many shorebird populations are rapidly declining and a high nest predation rate is one of the threats facing these populations. Thus, factors that affect predation and how to manage it in an effective way are receiving increased attention. READ MORE

6. 4. Conservation biology and genetic structure of fringe populations of the scarce heath butterfly in Sweden

   Author : Anna Cassel; Volker Loeschcke; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; fragmentation; genetic structure; mobility; inbreeding; habitat requirements; Lepidoptera; Genetik; Clinical genetics; Klinisk genetik; Conservation Biology; naturvårdsbiologi;

   Abstract : During the past century, about 82% of meadows and pastures have been lost in Sweden, with negative consequences for their flora and fauna. An example is the scarce heath butterfly, which is one of the red-listed species threatened by such habitat loss through afforestation. READ MORE

7. 5. Microclimate at range margins : Consequences for boreal forest understory species

   Author : Caroline Greiser; Kristoffer Hylander; Johan Ehrlén; Eric Meineri; Miska Luoto; Alistair Jump; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; microclimate; species distribution; range dynamics; boreal forest; canopy cover; topography; soil moisture; air humidity; bryophytes; lichens; vascular plants; biotic interactions; forest management; biodiversity conservation; ekologi och evolution; Ecology and Evolution;

   Abstract : A warmer climate will shift species distributional range margins poleward, but near-ground microclimates may modify these shifts. Cold-adapted northern species at their rear edge may survive locally in microrefugia with a colder microclimate, and warm-adapted southern species at their leading edge may colonize stepping stone habitats with a warmer microclimate.
