Who observed that 'within a region, species richess icreased with increasing explored area but only upto a limit'

Which of the statement are in accordance with the observation of geographer Alexander von Humboldt ? I. Within a region species, richness increases with increasing explored area but within a limit. II. The relation between species richness and area is a rectangular hyperbole. III. The richness of species decreases with the increasing explored area. IV. There is no relation between the explored area and species richness .

Alexander von Humboldt is associated with (a.) species - area relationship (b.) log S = log C + z logA (C.) Within a region , species richness increases with the increasing limited explored area. (d.) Increased diversity contributes to higher productivity. (e.) Species diversity increases with the loss of keystone species.

The relation between specises richness and area is described on a logarithmic scale by the equation [where S = species richness, A = area, Z = slope of the line (regression coefficient ), C= Y - intercept]

Indicate whether the following statements are true or false : (i) New York in temperate area has 56 species of birds. (ii) Tropical biomes unlike temperate ones, are more seasonal, relatively less constant and predictable. (iii) Relationship between species richness (S) and area (A) turned out to be rectangular hyperboia on a logarithmic scale. (iv) Slope of regression (Z) is 1.15 for frugivorous birds and mammals in tropical forests of different continents.

Assertion : If the species-area relationship are analysed among very large areas like the entire continents, the value of Z, i.e., slope of line in the range of 0.1 to 0.2. Reason : The value of Z, i.e., slope of line of species area relationship lies in the range of 0.6 to 1.2 when analysis is done among small areas.

A simple pendulum made of bob of mass m and a metallic wire of negligible mass has time period 2 s at T = 0^(@)C . If the temperature of the wire is increased and the corresponding change in its time period is plotted against its temperature, the resulting graph is a line of slope S . If the coefficient of linear expansion of metal is alpha then value of S is :
