Melanism is found in many animal species. This phenomenon is caused by a large amount of melanin pigment and causes an abnormal black or dark brown colour of the outer covers. Melanistic individuals are usually quite rare in nature. However, there are a number of examples indicating that melanistic colouring in animals can be adaptive under certain conditions and be supported by natural selection. These examples include the phenomenon of industrial melanism, described in the birch moth Biston betularia, as well as...

The purpose of the present study is to apply the new methods of multi-parametric analysis to moonquakes. It should be noted such physical phenomena as moonquakes are some kinds of complex systems. As the works in which analysis of moonquakes observations is conducted have shown, lunar seismophysics is much more complex process than Earth's geophysics. This is why to study the physical nature of moonquakes and their parameters it is necessary to use methods of statistical physics and robust estimates. Currently, th...
