2. 1. Stress in chickens : Effects of domestication and early experience on behaviour and welfare

   Author : Maria Ericsson; Per Jensen; Linda Keeling; Bjarne Braastad; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : The domestication is the process where animals have adapted to human conditions. A prerequisite for domestication is tame behaviour towards humans and subsequently, selection for other desirable traits took place which led to changes in several behavioural and physiological parameters.

4. 2. Stress-induced BVOC emissions from forests in Sweden

   Author : Erica Jaakkola; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Volatile organic compounds; Plant stress; Forests; Volatile emissions; spruce bark beetle infestations; ozone stress; wildfire recovery; Picea abies Norway spruce ; Betula pubescens ssp. czerepanovii; Pinus sylvestris Scots pine ; sweden;

   Abstract : A changing climate is expected to lead to more extreme weather events, such as an increased frequency of droughts and forest fires. Changing forest conditions can offer benefits to species such as insects, including bark borers that thrive in warm conditions. READ MORE

5. 3. Exosomes and the NKG2D receptor-ligand system in pregnancy and cancer : using stress for survival

   Author : Malin Hedlund; Lucia Mincheva-Nilsson; Susanne Gabrielsson; Umeå universitet; []
   Keywords : Exsosomes; NKG2D; MICA; MICB; ULBP; human placenta; trophoblast; syncytiotrophoblast; thermal stress; oxidative stress; leukemia; lymphoma; immunologi; Immunology;

   Abstract : Although not obvious at first sight, several parallels can be drawn between pregnancy andcancer. Many proliferative, invasive and immune tolerance mechanisms that supportnormal pregnancy are also exploited by malignancies to establish a nutrient supply andevade or edit the immune response of the host.
