  1. 6. Polycystic ovary syndrome : A Drosophila Melanogaster Melanogaster disease model induced by DHT and/or high sugar diet

    University essay from Högskolan i Skövde/Institutionen för hälsa och lärande

    Author : Andreas Mlekov Andersson; [2019]
    Keywords : Polycystic ovary syndrome; PCOS; DHT; high sugar diet; drosophila melanogaster;

    Abstract : Polycystic ovary syndrome is an endocrine disorder with symptoms of hyperandrogenism, insulin-resistance and anovulation in women which creates a disposition for other disorders, like Type 2 Diabetes. Drosophila Melanogaster flies have short generation, low cost-management and share several signaling pathways with humans and are therefore an excellent tools to study disease aetiology – yet no such model exists for PCOS.

  3. 7. Factors explaining variation in the fecundity of female Baltic salmon (Salmo salar) : the influence of length, body condition and growth rate at sea

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Ulrika Tollerz Bratteby; [2019]
    Keywords : Atlantic salmon; Baltic Sea; fecundity; body size; body condition; growth rate; scale reading;

    Abstract : Understanding factors influencing variation in fecundity is crucial to manage Atlantic salmon (Salmo salar) populations in the Baltic Sea. Larger individuals usually have a higher size-specific reproductive investment than smaller individuals, thus leading to a higher fecundity. READ MORE

  4. 8. The effect of sexual selection and mating on personality traits and behavior consistency of Callosobruchus maculatus

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Jiaqi Lu; [2019]
    Keywords : seed beetles; sexual selection; mating; personality traits;

    Abstract : Animals’ personality traits are defined as consistent behavior tendencies and the function of them in life-history strategy and reproductive success has been given a lot of explanations in a large amount of research. However, the behavior consistency of individuals in different sexes, mating status and selection regimes is rarely mentioned. READ MORE

  5. 9. Effects of global warming on Eurasian perch (Perca fluviatilis) in the Baltic Sea : does the growth response to increased temperatures differ along a latitudinal gradient?

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Mattias Grunander; [2018]
    Keywords : body-length at age; growth; size dependent growth; Perca fluviatilis; climate change; temperature; Baltic Sea; latitude;

    Abstract : Anthropogenically caused climate change, i.e. global warming, is anticipated to affect all living organisms. Particularly ectotherms are predicted to show strong responses to the increased warming, as their body temperature closely tracks ambient temperatures and because body temperature profoundly affects many physiological functions e.

  6. 10. Population demography’s potential effect on stoichiometry : Assessing the growth rate hypothesis with demography

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Alexander Blochel; [2017]
    Keywords : Demography; insect populations; stoichiometry; growth rate hypothesis;

    Abstract : The elemental composition within structured insect populations was tested by creating a new method to analyze how variables (survival, growth and fecundity) within a population matrix could potentially affect the stoichiometric regime of a structured population at steady state. This was done by focusing on if the growth rate hypothesis, which states that there is a linear relationship between an individual growth rate and the percent of phosphorus within the individual, works at a population level.
