If we conduct a field survey for this purpose then which type of questions are asked from the respondent?
Spectral evidence can be used as a guide to the degree of desertification and the extent to which plants and animals are affected
You compare diversity of species in different areas and perform ordination on environmental conditions :)
Hello Muhammad; In the southwestern USA, one of the subjects of interest is the rate at which various species of plants are moving upward on the mountain slopes. The evidence so far indicates that, as the low elevation flat deserts are heating and drying, many of the bands of vegetation are moving to higher elevations. That phenomenon is equivalent to the poleward migration of plant communities across the continents.
Researchers in your area are probably interested in that subject. The research involves looking at historical records of the occurrence of species in particular locations. Herbariums in the region will have many of those records. Best regards, Jim Des Lauriers
Dear Muhammad,
To Know the Desertification impact on flora,
Knowledge on plant physiology particularly on stress physiology is essential. Desertification refers to less water availability and it leads to accumulation of Mineral nutrients like sodium, potassium etc.Plants adapt to this conditions they became succulent and exhibits CAM Photosynthesis. All the plants are unable to adapt such conditions. Hence Plant diversity decreases. Decrease in plant diversity leads to decrease in productivity. Least productive ecosystems doesn't support maximum faunal diversity.
