    • Institute for Complex Systems SimulationCitizen Science 3
    • Institute for Complex Systems SimulationInternet and Smartphones• Easy – Communication – Data gathering – Communities 4
    • Institute for Complex Systems SimulationInternet and Smartphones GPS Camera LightProximity Microphone Image sourced from www.htc.com/uk/smartphones Accelerometer 5
    • Institute for Complex Systems SimulationBiodiversity Monitoring• Experts• Enthusiasts• Traditional methods – Manual – Require expertise The New Forest Image source from http://en.wikipedia.org 6
    • Institute for Complex Systems SimulationBioacoustics• Animals can be elusive – In particular birds, bats, insects• Better detected by their sound• Better classified by their sound (speciation)Example• iBats – Bat mobile Image sourced from ibats.org.uk 7
    • Institute for Complex Systems SimulationThe New Forest Cicada• Native to the UK• Only in the New Forest• Call at ~13.5 kHz• Most people >40 can’t hear it• Those who can, hear it even 60m away Image above sourced from http://www.pbase.com/ima Image source from http://forestvwhire.com ge/83110353 8
