    Sammanfattning : The embryonic development of anurans is known to be temperature-dependent and well-studied. Oviposition of Rana temporaria (common frog) in the northern temperate climate zone occurs as soon as the ice melts on water bodies. This early oviposition can take place in waters below 5 °C.

  3. 2. Prey specialization and diet of frogs in Borneo

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Kristoffer Ahlm; [2015]
    Nyckelord :specialization; frogs; diet; stomachflushing;

Overall, frogs are viewed more as generalists than specialists in terms of their diet. However, despite earlier studies, there are still gaps in our knowledge regarding what frogs tend to eat and the degree of specialization. LÄS MER
