  2. 16. Molecular population genetics of inducible defense genes in Populus tremula

    Author : Carolina Bernhardsson; Stefan Jansson; Santiago González-Martinez; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Populus; herbivore defense; adaptation; population genetics; population structure; association mapping; complex traits; evolutionär genetik; evolutionary genetics;

    Abstract : Plant-herbivore interactions are among the most common of ecological interactions. It is therefore not surprising that plants have evolved multiple mechanisms to defend themselves, using both constitutive chemical and physical barriers and by induced responses which are only expressed after herbivory has occurred.

  4. 17. Multiple stressors in rotifer communities: : Effects of predation, climate change, and brownification

    Author : Huan Zhang; Enhet akvatisk ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Climate change; community dynamic; brownification; heat wave; inducible defense; rotifer; plasticity; multiple stressors; Predation; prey;

    Abstract : Most organisms on Earth live in an environment where they are exposed to multiple pressures, including predation and climate change. In many aquatic ecosystems, organisms have to handle additional challenges such as brownification, co-occurring with climate warming. READ MORE

  5. 18. Psychotic disorders in the Lundby population 1947-1997: Incidence, life-time prevalence and predictors related to personality and behaviour

    Author : Mats Bogren; Lund Psykiatri; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; psychotic disorder; prevalence; bipolar disorder; incidence; prospective study; methodology; community survey; the Lundby Study.; epidemiology;

    Abstract : The aims were to analyze the first incidence, age-at-onset, prevalence and personality related predictors of psychotic disorders in the Lundby population (n=3563) – a community population followed through four waves of field study 1947-1997. Case ascertainment included interviews, registers, case notes and key informants. READ MORE

  6. 19. Plant-seed predator interactions – ecological and evolutionary aspects

    Author : Hannah Östergård; Johan Ehrlén; Peter Hambäck; William Kunin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; apparent competition; community context; fruit abortion; defence; host range; monophagous; offence; oligophagous; plant-animal interactions; pre-dispersal seed predation; selection; spatio-temporal variation; Biology; Biologi; Plant Ecology; växtekologi;

    Abstract : Plant-animal interactions are affected by both abundance and distribution of interacting species and the community context in which they occur. However, the relative importance of these factors is poorly known. READ MORE

  7. 20. Below, above and beyond – seagrass ecosystem functions in a connected coastal landscape

    Author : Theodor Kindeberg; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; coastal adaptation; beach wrack; eelgrass; carbon cycling; infauna; seagrass restoration; nature-based solution; biodiversity; eddy covariance; functional traits; Zostera marina;

    Abstract : Seagrass meadows constitute important habitat for a plethora of organisms, rendering them important habitats for conserving biodiversity. Seagrass meadows also modify the environment by attenuating wave and current energy. READ MORE
