and seas, -where the study of the biogenous sound "background has opened 

 new practical vistas for perfecting methods of underwater navigation. 

 Such investigations, carried out in France and other countries, have 

 led to the idea of drawing up "acoustic underwater sea maps." 



Thus, one can see that the present successes of the science of 

 bioacoustics, especially in its geographical aspects, have found in- 

 creasing application in related biological fields, touching, as it does, 

 upon many major problems, among which one can primarily number bionics, 

 the laws governing animal behavior, ecology, geography, the evolution 

 of populations and associations, and, in addition, problems concerning 

 the formation of forms and species, structure, formation and dynamics of 

 fauna, etc. Further development in the study of bioacoustics promises 

 data of the greatest interest in all the above fields.
