1. 16. Adolescents Born Extremely Preterm : Cognitive, Behavioural and Relational Outcomes

   Författare :Anne-Li Hallin; Institutionen för psykologi; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; health; attachment; behaviour; extremely preterm; Adolescents; social support; cognition;

   Sammanfattning : The aim of this thesis was to evaluate long-term outcomes in a regional cohort of adolescents born extremely preterm (before the 29th gestational week) and compare them to full-term born controls. Fifty-two prematurely and 54 full-term born individuals were recruited from a follow-up study at 10 years of age. LÄS MER

   Sammanfattning : Background: Men who have sex with men (MSM) are a key population for HIV worldwide. Overall HIV incidence is declining but over the past years the proportion of HIV diagnoses attributed to sex between men has remained high in Europe. LÄS MER

4. 18. Interaction between dispersal and behavioural syndromes - empirical approach in a fragmented population of passerine birds

   Författare :Gregory Daniel; Blandine Doligez; Lars Gustafsson; Thierry Boulinier; Uppsala universitet; []
   Nyckelord :dispersal; behavioural syndromes; heritability; personality traits; neophobia; aggressiveness; risk-taking behaviour; collared flycatcher; Ficedulla albicollis; dispersion; syndromes comportementaux; héritabilité; traits de personnalité; néophibie; aggressivité; prise de risque; gobemouche à collier; Ficedulla albicollis; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology;

   Sammanfattning : Dispersal is a key life history trait for ecological and evolutionary processes in wild populations. The latest research has particularly focused on the correlation between behavioural traits and dispersal, in order to emphasize the existence of behavioural syndromes of dispersal, and on the estimation of the genetic basis of the dispersal behaviour.

5. 19. Behavioural, physiological and morphological correlates of life-history in killifishes − a macroevolutionary approach

   Författare :Simon Eckerström-Liedholm; Alejandro Gonzalez Voyer; Björn Rogell; Alastair Wilson; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; brain size evolution; comparative analysis; life-history continuum; risk-taking behaviour; sexual selection; trade-offs; etologi; Ethology;

   Sammanfattning : Life-histories commonly evolve along a continuum from short-lived and fecund, to long-lived and less fecund. Because life-history traits are mostly components of reproduction and survival, understanding the causes and consequences of life-history variation is at the core of evolutionary biology. LÄS MER

7. 20. Causes and Consequences of Impulsivity in Red Junglefowl

   Författare :Laura Garnham; Hanne Lovlie; Per Jensen; Neeltje Boogert; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Behaviour; Cognition; Gallus gallus; Impulsivity; Inhibitory control; Red junglefowl;

   Sammanfattning : Throughout the animal kingdom, animals vary in cognition (i.e., how they acquire, process, store, and act on environmental information). Yet, the causes and consequences of this variation are currently unclear. LÄS MER
