What is an example of phytogeography?
For example, a relict area is an area surviving from an earlier and more exclusive occurrence. Mutually exclusive plants are called vicarious (areas containing such plants are also called vicarious). The earth’s surface is divided into floristic region, each region associated with a distinctive flora.
What is phytogeography in ecology?
Phytogeography is the study of the distribution of plants or taxonomic groups of plants and its focus is to explain the ranges of plants in terms of their origin, dispersal, and evolution (Matthews et al., 2003).
What is biogeography phytogeography and Zoogeography?
Organisms and biological communities often vary in a regular fashion along geographic gradients of latitude, elevation, isolation and habitat area. Phytogeography is the branch of biogeography that studies the distribution of plants. Zoogeography is the branch that studies distribution of animals.
Why is phytogeography important?
Phytogeography is concerned with all aspects of plant distribution, from the controls on the distribution of individual species ranges (at both large and small scales, see species distribution) to the factors that govern the composition of entire communities and floras.
Which is the best description of phytogeography?
Phytogeography definition The study of the geographic distribution of plants. The geography of the distribution of plant life.
What is phytogeography describe phytogeographical regions of India?
Phytogeography Region # 4. It includes dry deciduous (Scrub) and Moist deciduous vegetation. Sometimes the Indus region and Gangetic region, because of similar type of vegetation, is called as Indo Gangetic plain. The Gangetic plain divided into upper Gangetic plain, Lower Gangetic plain and Sundarbans.
What is phytogeography describe Phytogeographical regions of India?
What is phytogeography describe botanical regions of India?
A phytogeographical region is defined as an area of uniform climatic conditions and having a distinctly recognisable type of vegetation. According to D. Chattarjee (1962), India can be divided into nine phytogeographical regions.
How many phytogeographical zones are present in India?
According to D. Chattarjee (1962), India can be divided into nine phytogeographical regions. This region comprises north and south Kashmir, part of Punjab and Kumaon region of Uttaranchal.

What is phytogeography?
Phytogeography (from Greek φυτόν, phytón = “plant” and γεωγραφία, geographía = “geography” meaning also distribution) or botanical geography is the branch of biogeography that is concerned with the geographic distribution of plant species and their influence on the earth’s surface.
What factors affect the distribution of phytogeography?
The relative position of the 6 continental land masses and large number of islands play an important role in the distribution of various types of plants over the surface of the earth. Factors responsible for phytogeographical distribution can be divided primarily into 2 broad categories:
What is phytogeography According to Wulff?
Wulff (1943) states that Phytogeography is the study of distribution of plant species in their habitats and elucidation of origin and history of development of floras. According to Croizat (1952), Phytogeography is the study of migration and evolution of plants in time and space.
What is the difference between geobotany and phytogeography?
Geobotany, by contrast, focuses on the geographic space’s influence on plants. Phytogeography is part of a more general science known as biogeography. Phytogeographers are concerned with patterns and process in plant distribution.
