   Sammanfattning : An appreciation of the role of mutualism is essential when studying ecology and evolution in most ecosystems. Information covering aspects of mutualistic interactions can serve as a complement to the somewhat one-sided perspective from the 1950’s and 60’s that is used when teaching biology. LÄS MER

3. 12. Investigating anticipatory behaviours in lambs

   Författare :Claes Anderson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Many animals kept by humans receive cues that predict future events for example food or being let out. The interval between cue and future event may however be delayed. In the best of worlds, animals may not experience such waiting as negative and it is even suggested that the anticipation following such cues is experienced as pleasurable. LÄS MER
