Question
8. What vertebrate class are Ambystoma salamanders in? 9. Characterize the dispersal ability of Ambystoma salamanders. What limits their dispersal ability? 10. What type of population structure do Ambystoma salamanders have? 11. What two types of biomes do they require to complete their life cycle? 12. What might happen if one of their habitats is destroyed? 13. What might happen if both types of habitat are available but a barrier is between them? Using the figure below, answer the following questions: 14. Which population would you predict to have the lowest genetic diversity? Why? 15. If Population C had a local extinction, what might happen? 16. What are barriers to salamander migration in this figure? 17. Over time, what might happen to the genetic diversity of Population A? 18. If Population A goes extinct, is that habitat likely to be recolonized? Farm field Forest Road Farm field ForestExplanation / Answer
8)Sarcopterygii,terrestrial vertibrates like Amphibians(salamander,frogs).
9)Disperse ability deals with the capcity of the animal to move from from one habitat to another according to the changing climate and distribution of food for survival.
Salamnders move to and from theit water ecosystem like ponds and river during unfavorable condition like high predation and low food availability.They can disperse upto the rate of 9-10% and move diatance of 1000m wich hgelp maintainance of pipulation connecticity and growth.Changing of multiple breeding site as per the season is seen among juvenile salamnders compared with adult.
Disperrse abilitity limitation-River barrier and refuge river
10)Metapopulation-Salamnders can escape prom extiction by dispersal and recolonization in ponds and rivers as they are independent of variability in population.
11)Aquatic larvel phase and erresrrial juvenile life
12)Reduction in population and sometime extinction.
13)stops gene flow and results in two or more isolated population formation.
14)Forsest A population have low population genetic diversity as low in breeding due to barrier formation in forest ecosystem by constructing fields.
15)It reduce the genetic diversity in moderate percentage and the gene flow among population C is lost.
16)Farm field is the barrier for salamander population in figure.
17)Population A inbreed and grow furthure as isolated population.As the time lapse the A population will loose the ability to breed with salamnders in population B,C and D.
18)No,the recolonization of population A is not possible after extinction.
