  2. 1. Nocturnal enuresis and rapid maxillary expansion : – long-term effect, prognostic variables, respiration during sleep and quality of life

    Author : Ingrid Jönson Ring; Bazargani Farhan; Tryggve Nevéus; Agneta Markström; Maria Ransjö; Uppsala universitet; []
    Keywords : Rapid maxillary expansion; nocturnal enuresis; sleep disordered breathing; respiration; polygraphic sleep recording; quality of life.; Medicinsk vetenskap; Medical Science;

    Abstract : Background:The orthodontic technique rapid maxillary expansion (RME) has been reported to have a potentially curative effect on nocturnal enuresis (NE). The mechanism behind this is unknown but could possibly be due to placebo and/or effects on respiration during sleep. READ MORE

  4. 2. Extending dynamic vegetation models to simulate range shifts

    Author : Deborah Zani; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dynamic vegetation model; range shift; migration; paleovegetation;

    Abstract : In response to rapid climate change and increasing human pressure, a wide variety of taxa have shifted their distribution in the past decades (range shift), with important consequences for ecosystem services and human health and economy. However, it is not yet clear whether most species will be able to track their favourable habitats or lag behind the climate signal (migration lag). READ MORE

  5. 3. Life history evolution during a climate-driven butterfly range expansion

    Author : Mats Ittonen; Karl Gotthard; Philipp Lehmann; Christopher Wheat; Sarah Diamond; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; climate change; diapause; genomics; insect cold tolerance; life cycle; local adaptation; parallel evolution; photoperiodism; reciprocal transplant; zoologisk ekologi; Animal Ecology;

    Abstract : Climate change pushes species polewards and upwards – as temperatures rise, species move to areas that were previously too cold for them. During range expansions, species encounter unfamiliar environmental conditions, which may require evolutionary adaptation, but expanding populations may often be hampered by their genetic and demographic properties.

  6. 4. Genetic Identification of Corkwing Wrasse Cleaner Fish Escaping from Norwegian Aquaculture

    Author : Ellika Faust; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Conservation; Population structure; Genetics; Aquaculture; Hybridization; Corkwing wrasse; Cleaner fish; Sea lice; Symphodus melops; Escapee; Range expansion;

    Abstract : The genetic impact of farmed fish escaping aquaculture is a highly debated issue. However, non-target species, such as cleaner fish that are used in fish farms to remove parasitic sea lice, are rarely considered. READ MORE

  7. 5. Modelling the Evolution of Species’ Ranges

    Author : Martin Eriksson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Range expansions; Range margins; Population genetics; Evolutionary biology; Local adaptation; Environmental selection; Phenotypic plasticity; Computer simulations;

    Abstract : The fact that species have limited ranges is often due to a limited ability to adapt to the environmental conditions that occur outside their geographic ranges. However, due to ongoing climate change, the environmental conditions within species’ geographic ranges may change in the near-future. READ MORE
