Please help STAT with these questions. Will rate, thank you so much!
The wood turtle (Glyptermys insculpta) is a small, long-lived turtle that is endangered through much of its range in North America. As their populations shrink in size, it becomes even more difficult for turtles to find mates, and small populations have steadily become smaller. What best describes what the wood turtles in small populations are experiencing? an extinction vortex O habitat loss O climate change Question 59 1.67 pts How is habitat fragmentation related to biodiversity loss? Less carbon dioxide is absorbed by plants in fragmented habitats. O In fragmented habitats, more soil erosion takes place. Populations of organisms in fragments are smaller and thus more susceptible to extinction. O Animals are forced out of smaller habitat fragments O Fragments generate silt that negatively affects sensitive river and stream organisms
Explanation / Answer
58. An extinction vortex. The term was coined by Gilpin and Soulé and refers to process that declining population undergo when a mutual reinforcement occurs among biotic and abiotic processes that drives the process to extinction.
59. Populations of organism in fragments are smaller and thus more susceptible to extinction. Because reproductive fitness is greatly reduced in fragmented population.
60. Reproductive rates may decrease.|| Genetic diversity decreases.
61. High genetic diversity. Increased genetic diversity indicates that population is resilient and persistent. Thus the species has reduced extinction threat.
62. Alternation or destruction of physical habitat. Among the evil quadrant of biodiversity habitat loss accounts for major species destruction.
