  2. 1. Life histories and population dynamics

    Author : Annie Jonsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : During the last decades there has been a growing interest and attention to random variation in population densities and their causes. It has been shown that even in constant environments (deterministic population growth) the dynamics of populations can display random like behaviour depending on parameter values. READ MORE

  4. 2. Networks and epidemics - impact of network structure on disease transmission

    Author : Jenny Lennartsson; Uno Wennergren; Annie Jonsson; Meggan Craft; Högskolan i Skövde; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Natural sciences; Naturvetenskap;

    Abstract : The spread of infectious diseases, between animals as well as between humans, is a topic often in focus. Outbreaks of diseases like for example foot-and-mouth disease, avian influenza, and swine influenza have in the last decades led to an increasing interest in modelling of infectious diseases since such models can be used to elucidate disease transmission and to evaluate the impact of different control strategies.

  5. 3. Network analysis and optimization of animal transports

    Author : Nina Håkansson; Uno Wennergren; Annie Jonsson; Vittoria Colizza; Högskolan i Skövde; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Naturvetenskap; Natural sciences;

    Abstract : This thesis is about animal transports and their effect on animal welfare. Transports are needed in today’s system of livestock farming. Long transports are stressful for animals and infectious diseases can spread via animal transports. READ MORE

    Abstract : Aquatic organisms are constantly at risk of being exposed to potentially harmful chemical compounds of natural or anthropogenic origin. Biological life can for instance respond to chemical stressors by changes in gene expression, and thus, certain gene transcripts can potentially function as biomarkers, i.e. READ MORE

  7. 5. Metabolic factors and cancer risk : prospective studies on prostate cancer, colorectal cancer, and cancer overall

    Author : Tanja Stocks; Pär Stattin; Håkan Jonsson; Annie Lukanova; Jaap Seidell; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Urology and andrology; Urologi och andrologi; epidemiologi; Epidemiology;

    Abstract : Background: A large number of prospective studies have shown that overweight and diabetes are related to an increased risk of many cancers, including colorectal cancer. In contrast, diabetes has been related to a decreased risk of prostate cancer, and overweight has been related to an increased risk of fatal, but not of incident, prostate cancer. READ MORE
