Chronobiology is the study of biological rhythms. The best understood cycles are those with circadian 24 hour periods that modulate the temporal dynamics of physiology and behaviour of all higher organisms and some bacteria. Four model organisms have been widely used to study the underlying biology of circadian clocks, Cyanobacteria, the fungus Neurospora, the fruitfly Drosophila, and the mouse. CINCHRON is an integrated European centre of excellence for the research training of researchers in the emerging multidisciplinary field of Comparative INsect CHRONobiology.The 2017 Nobel Prize for Medicine or Physiology was awarded jointly to three of our colleagues, Jeffrey Hall and Michael Rosbash (both at Brandeis University, Boston, USA) and Michael Young (Rockefeller University, New York, USA) for their work on the molecular dissection of the circadian clock in Drosophila. Our warmest congratulations to these outstanding fly molecular geneticists for their achievements, which is particularly heartfelt because seven of the principle investigators of CINCHRON have worked and published with Hall and Rosbash.Insect clocks, both circadian and seasonal, are vital for adaptation to the environment and recent global patterns of climate change mean that insect pests and vectors of disease are expanding their ranges into Europe. Consequently there is an urgent need to study the circadian clocks of these insects and how they synchronise to the environment.CINCHRON will contribute to the integration and cohesion of future European research efforts in solving pure and applied biological problems.
Our investigations will provide the first basis in understanding the role of the circadian clock in seasonal adaptation using the well characterized model Drosophila melanogaster. In addition, we will contribute to the understanding of circadian clock evolution by investigating fruit fly species adapted for a life at different latitudes.

Animals have to adapt to seasonal changes in the environment. A too late adaptation to the coming winter will definitively cause their death. Insect start to hibernate (=diapause) when temperatures drop and day-length (photoperiod) decreases below a certain critical value. It is generally thought that the circadian clock is crucial to measure day-length, but the mechanisms how this is done and how the signals about day-lengths are transformed to the diapause inducing hormonal centres in the insect brain are largely unknown.
This Marie Curie Network aims to uncover the mechanisms of photoperiodic control in four model species: The parasitoid wasp, Nasonia vitripennis, the Lindenbug, Pyrrhochoris apterus, the Olive fly, Bactrocera oleae and the genetic model system Drosophila melanogaster. ..more
