What is related to 1877?
 
A 'biota' is the total collection of organisms of a geographic region or a time period, from local geographic scales and instantaneous temporal scales all the way up to whole-planet and whole-timescale spatiotemporal scales. The biotas of the Earth make up the biosphere. 

The term was suggested in 1916 by Clements, originally as a synonym for biotic community of Möbius (1877).
