  1. 1. Countergradient variation and compensatory growth in Moor frog (Rana arvalis) along a replicated latitudinal gradient

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Sohini Mallick; [2022]
    Keywords : moor frog; countergradient variation; compensatory growth; latitudinal gradient;

    Abstract : For evolution to occur over time, it is necessary for animals and plants to show phenotypic variation. If the individuals within populations of a species do not show observable differences among themselves, there will be a lack of driving force for natural selection to act on and decide which characteristic gets inherited from one generation to the next.

  3. 2. 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.
