Animal Migration
Question 4
The sentence in introduction that points to a gap in our knowledge is that of evolvement in migration. It states that migrations is thought to have evolved in ungulates since it affords high quality forage access as well as reducing predator exposure especially in seasonal environments.
Question 7
The type of experiment used was the comparative demography. Productivity indices were used in determining the long-term basis of the distribution and migratory patterns of the resident animals. Surveys were used to conduct the data collection. In addition, observation ranked on the seasonal ranges as means of data sets with the view of between seventy and eighty percent coverage of all the populations. Regression and asses completed the statistical inferences in the research of migrations.
Question 10
The statement that best answers the question being asked in the research is due to the reason of apparent decline in the demographic benefits associated with resident elks in the Yellowstone ungulates. The coincidence featured heavily with growing numbers of the large carnivores. They are the elks prey. In addition, the habitat quality was reduced due to the long-term draught.
Question 12
Ecological conditions of the animal habitats form an integral part in determining the survival of the species, especially with lengthened periods. If the conditions favor migration, diminished quality translates into lesser migration patterns and numbers despite the landscape availability at the time. Consequently, if the habitats are protected, the same fate is suffered. Human activities are to blame for the constant changes to the geographic patterns that shape predation for the animals. In turn, due to the dependency of migration on the same activities, the effect is realized on a negative scale. Physical obstructions increase the vulnerability of the ungulates in migration.
