According to Ecologists and Evolutionary Biologists, the probable reason for speciation in tropics is not
(1) Speciation is generally a function of time, more time without environmental disturbances better chance of speciation
(2) No frequent glaciation unlike temperate regions in the past
(3) Constant environment supports niche specialisation
(4) Tropics had more adapted animals and had a high rate of reproduction so there is more diversity
……a… have remained relatively undisturbed for millions of years and thus had a long evolutionary time for……b..The constant environments promote…c..and had a greater species diversity.
Which of the following is correct?
(1) a-Tropical latitudes
(2) b-niche specialization
(3) c- species diversity
(4) b- constant environment
The higher diversity of tropics is actually favoured by except
(1) High solar energy
(2) Constant and predicatable environment
(3) No environmental disturbances like glaciations
(4) Animals with high reproductive rates
Alexander Von Humboldt:
Find the wrong one out.
(1) German Naturalist
(2) German Geographer
(3) First one to explore South American Jungles
(4) Gave Rivet Popper Hypothesis
The idea of Species Area Relationship was given by
(1) Edward Wilson
(2) Paul Ehrlich
(3) A.V. Humboldt
(4) Katherine Esau
According to Species-Area relationship-
(1) Within a region, species richness increased with increasing explored area, but only up to a limit
(2) Within a region, species evenness increased with increasing explored area without limit
(3) Within a region, species diversity increases with increasing area.
(4) Both A and B
