A study of the invasion of vegetation upon a new land surface formed by volcanic activity. Such studies as this aid one in breaking away from the older static view of vegetation and in seeing its more vital aspect. VAUGHAN, T. W. 1911. The Geological Work of Mangroves in Southern Florida. Smithsonian Miscell. Coll. (Quart. Issue), Vol. LII, pp. 461-464. Plants as agents in the formation of animal habitats. WEISS, F. E. 1909.

Surv. for 1908, pp. 1-56. An attempt is made to treat the environment and biota from both the dynamic or process standpoint--so far as the present processes are concerned--and genetically with regard to the development of the present conditions.

The environment and biotic associations are treated from the dynamic and genetic standpoint.
