Researchers including Dr Sasha Dall have discovered that individuals with the highest metabolic rates within populations should be the least pre-occupied with keeping track of changes in their environments that could lead them to sources of food.

Dr Jon Blount and a team of researchers have discovered that feeding wild blue tits in winter resulted in less successful breeding during the following spring meaning that feeding wild birds in winter may not be a benefit.

Zebra finches

Dr Nick Royle and a team of researchers have conducted a study into Zebra Finches and discovered that personality is not inherited from birth parents with external factors likely to play a bigger part.

Dr Clarissa House has been part of a team which has shown that plants, like animals, also have a battle of the sexes when it comes to raising their offspring.

Dr Andy Russell has co-authored a paper published in Ecology Letters that reveals the menopause evolved, in part, to prevent competition between a mother and her new daughter-in-law.


Research highlights


  • We show that badgers infected with bovine TB are less socially connected within their social groups but are more connected to badgers from other social groups than non-infected badgers; Covered by the BBC, The London Evening Standard and The Daily Express. PAPER: Weber, N., Carter, S. P., Dall, S. R. X., Delahay, R. J., McDonald, J. L., Bearhop, S., & McDonald, R. A. (2013). Badger social networks correlate with tuberculosis infection. Current Biology, 23(20), R915-R916.
  • We show that variation in metabolic rates among individuals within populations can explain dramatic differences in information use when it comes to food; Covered by Medical News Today and Europe Nouvelles. PAPER: Mathot, K. J., & Dall, S. R. X. (2013). Metabolic Rates Can Drive Individual Differences in Information and Insurance Use under the Risk of Starvation. The American Naturalist, 182(5), 611-620.
  • We show that, in zebra finches, "personality" differences are mainly inherited non-genetically; Covered by The Daily Mail and The Australian. PAPER: Schuett, W., Dall, S. R. X., Wilson, A. J., & Royle, N. J. (2013). Environmental transmission of a personality trait: foster parent exploration behaviour predicts offspring exploration behaviour in zebra finches. Biology Letters, 9(4), 20130120.
  • We show that male zebra finch song rate may give strange females a false impression of the male's condition but his partner cannot be fooled in this way; Covered by The Conversation, France 24, TV5 Monde and in a Science Update Radio (AAS) podcast.
