Excerpt from Principles of Geology, Vol. 2 of 2: Being an Inquiry How Far the Former Changes of the Earth's Surface Are Referable to Causes Now in Operation
But it is still more remarkable, that in the more widely separated parts the ancient continent, notwithstanding the existence of an uninterrupted land communication, the diversity in the specific character of the respective vegetations is almost as striking. Thus there is found one assemblage of species in China, another in the countries bordering the Black Sea and the Caspian, a third in those surrounding the Mediterranean, a fourth in the great platforms of Siberia and Tartary, and so forth.
The distinctness of the groups of indigenous plants, in the same paral lel of latitude, is greatest where continents are disjoined by a wide expanse of ocean. In the northern hemisphere, near the pole, where the extremities of Europe, Asia, and America unite or approach near to one another, a considerable number of the same species of plants are found, common to the three continents. But it has been remarked, that these plants, which are thus so widely diffused in the Arctic regions, are also found in the chain of the Aleutian islands, which stretch almost across from America to Asia, and which may probably have served as the chan nel of communication for the partial blending of the Floras of the adjoin ing regions. It has, indeed, been found to be a general rule, that plants found at two points very remote from each other, occur also in places intermediate.

The islands of the great southern Ocean exemplify these rules; the easternmost containing more American, and the western more Indian pianis.'i Madeira and Teneriff'e contain many species, and even entire genera, peculiar to them; but they have also plants in common with Portugal, Spain, the Azores, and the north-west coast Of Africa.

Paperback. Zustand: New. Print on Demand. This book examines how species are geographically distributed across the globe, and the laws that govern these distributions. The author draws on the work of earlier naturalists such as Buffon to demonstrate how species are not uniformly distributed, but rather are often confined to specific regions. These patterns are examined through the lens of botany, zoology, and the study of marine life. The author offers insights into the mechanisms that allow species to spread, including the effects of climate, the role of wind and water currents, and the agency of animals in transporting seeds and other propagules. The book concludes by discussing the implications of these findings for our understanding of the history of life on Earth and the potential for future changes in species distribution.
