    "abstract": "Time series of heartbeat activity of humans can exhibit long-range\ncorrelations. In this paper we show that such kind of correlations can exist\nfor the heartbeat activity of much simpler species like Drosophila\nmelanogaster. By means of the method of multifractal detrended fluctuation\nanalysis (MFDFA) we calculate fractal spectra $f(\\alpha)$ and $h(q)$ and\ninvestigate the correlation properties of heartbeat activity of Drosophila with\ngenetic hearth defects for three consequent generations of species. We observe\nthat opposite to the case of humans the time series of the heartbeat activity\nof healtly Drosophila do not have scaling properties. Time series from flies\nwith genetic defects can be long-range correllated and can have multifractal\nproperties. The fractal heartbeat dynamics of Drosophila is transferred from\ngeneration to generation.",
