Their natural habitat is from Argentina on north through Central America and into parts of Texas, New Mexico and Arizona.
Factors of the habitat are very misunderstood.
This is due to a lack of precise knowledge of the various habitat factors and also of the responses made by plants to these factors.
Ecological Classes.Many attempts have been made to divide plants and plant communities into classes depending on habitat factors.
Thus, associ- 1~e] ions of Agropyrum (Triticum) junceum, of Carex arenaria, of ~ ~nmophila (Psamma) arenaria, and of other plants occur on sa rid dunes: the associations are related by the general identity ph the habitat conditions, namely, the physiological dryness f d the loose soil; but they are separated by differences in f~1
In the present state of knowledge, however, this can only be done in a very meagre fashion; as the effect of habitat factors on plants is but little understood as yet either by physiologists or ecologists.
The Red river valley is a meeting ground for many species of plants whose principal habitat lies in some other quarter.
For example, among the land vertebrates the feet (associated with the structure of the limbs and trunk) may take one of many lines of adaptation to different media or habitat, either aquatic, terrestrial, arboreal or aerial; while the teeth (associated with the structure of the skull and jaws) also may take one of many lines of adaptation to different kinds of food, whether herbivorous, insectivorous or carnivorous.
Bees find a highly congenial habitat in Mexico, and some honey is exported.
Vipera have the same habitat in British waters as certain species of soles.
Associated with this diversity of habitat is great variety in general form and manner of growth.
A few algae approach the ordinary terrestrial plants in their capacity to live in a sub-aerial habitat subject only to such occasional supplies of water as is afforded by the rainfall.
Its special habitat is salt plains, as on the coast-line of Gujarat and Orissa, where herds of fifty does may be seen, accompanied by a single buck.
Its habitat extends some 200 m., from latitude 36° to 39°, nowhere descending much below an altitude of 5000 ft., nor rising above 8000 ft.
Ii., and their habitat is not specified.
As for a habitat, if I were not permitted still to squat, I might purchase one acre at the same price for which the land I cultivated was sold--namely, eight dollars and eight cents.
