Chapter 56, Problem 6TYK
Summary Introduction
Introduction: The variability among the organisms such as plants, animals, fungi, bacteria, human beings, and the communities or the ecosystem such as aquatic, terrestrial, forest, marine in which the habitat is called as biodiversity. It is the combination of three levels of diversity namely species diversity, genetic diversity, and ecosystem diversity.

Habitat fragmentation can reduce biodiversity by
a. introducing more native species into a habitat
b. sterilizing for pollution control
C. decreasing human use of natural resources
d. eliminating vast tracts of forests
e. withdrawing an essential resource from native species
Habitat fragmentation results from human activities that change large blocks of landscape, leading to many negative effects on species and ecosystems. Which of the following is
not one of the possible consequences of fragmentation?
A. reduction of available habitat
O B. increasing degradation of habitat patches
C. increasing wind speeds and temperatures at patch edges
D. spatial isolation of patches
E. increase in top predators present in patches
Assuming all other factors are equal, which statement about the success of core natural areas as a conservation measure is false?
OA. Areas with compact shapes are superior to areas with less compact shapes.
B. One large reserve is superior to a few small reserves with the same total area.
C. Several reserves far apart are superior to the same number of reserves close together.
O D. Reserves connected by habitat corridors are superior to unconnected reserves.
Areas encompassing a range of vegetation types are superior to those with a uniform composition.

- What is the importance of endemic hotspots to biodiversity conservation? A. Endemic hotspots contain many species found nowhere else, so the conservation of a small amount of area will protect many species. B. Endemic hotspots have the highest species diversity, so their conservation will protect the most species. C. Endemic hotspots are those that contain species vital to human existence, ssuch as medicinal species, and therefore humans rely on these areas the most. D. Endemic hotspots are where speciation rates are thegreatest, so the conservation of those areas will likely lead to the formation of many species in the future. E. Endemic hotspots have very low ecosystem stability, therefore require more protections to avoid extiction.arrow_forwardThe study of how habitat-type distribution across a landscape is known as: A.
