Write a note on biogeographic factors that affect species diversity.
Important Questions on Ecology and Conservation
Give one significant contribution of the following scientist:
E. Wilson
Define biodiversity. What are the major causes of loss of biodiversity? Give two conservation strategies to protect biodiversity.
Select the correct option for the given statements (where a = Columbia, b = New York)
Statements:
X = Number of birds species in "a" is higher than that in "b"
Y = More solar energy is available in "b" than in "a"
Z = Productivity in "a" is higher than in "b"
Statement I : Alpha diversity is the species diversity between two adjacent ecosystems and is obtained by comparing the number of taxa unique to each of the ecosystems.
Statement II : Gamma diversity is the measure of the overall diversity for different ecosystems within an ecological region.
Given below is the representation of the extent of the global diversity of invertebrates. What groups the four portions (A-D) represent respectively?
A. The duration of time available for species diversification is limited.
B. Solar energy and water resources are available in abundance.
C. Tropical climates are not constant and cannot be predictable.
D. Tropical latitudes have remained relatively undisturbed for millions of years.
