16. Life History Strategies in Linnaea borealis
Sammanfattning : About 70% of the plant species in the temperate zone are characterised by clonal growth, clonal species are also in majority in the Arctic and Subarctic where they affect the structure and composition of the vegetation. It is therefore of great importance to increase our knowledge about clonal plants and their growth and life histories. LÄS MER
17. Wellbeing in Old Age : Life history, sense of coherence and social networks in relation to health
Sammanfattning : A conceptual model for the relationships between wellbeing and health in old age were construed. In the model life history evaluations, current sense of coherence (SOC) and social network characteristics defined wellbeing. Health was defined as reported symptoms, subjective health and health care utilization. LÄS MER
18. Telomeres in ecology and evolution: Hypotheses and connections between telomere length, infections and life history trade-offs
Sammanfattning : Studying life history strategies is crucial for understanding the diversity among organisms. The trade-offs in traits related to survival, self-maintenance and reproduction play an important role in the variation of life histories and can be adjusted in response to environmental and physiological factors.

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