host density造句

• It is only in cases of near-extinction where sexually transmitted diseases show any dependence on host density.
• The ranking is based on penetration of telephone line density, TV set density and Internet hosts density.
• Some examples of host density independent diseases are sexually transmitted diseases in both humans and other animals.
• As sexual contact is required in nearly all sexually reproducing species, transmission is not very host density dependent.
• Numerical response in parasitism is still measured by the change in number of adult parasites relative to change in host density.
• Host density independent diseases show no correlation between the concentration of a given host population and the incidence of a particular disease.
• Eventually, however, the advantage of host density diminishes as the density becomes too great for the vector to maintain its natural ecological relationship with the host, and transmission decreases.
• Threshold host density ( N T ) only applies to density dependent diseases, where there is an " aggregation of risk " to the host in either high host density or low host density patches.
• Threshold host density ( N T ) only applies to density dependent diseases, where there is an " aggregation of risk " to the host in either high host density or low host density patches.
• Threshold host density ( N T ) only applies to density dependent diseases, where there is an " aggregation of risk " to the host in either high host density or low host density patches.
• Yakob and coauthors calculated the likelihood of natural host switching from the long-tailed macaque monkey to humans using an evolutionary invasion analysis and demonstrated how this switch was contingent on relative host densities and individual-level mosquito feeding preferences.
• Parasites can demonstrate a more pronounced numerical response to changes in host density since there is often a more direct connection ( less time lag ) between food and reproduction in that both needs are immediately satisfied by its interaction with the host.
• When low host density causes an increase in incidence of parasitism or disease, this is known as inverse host density dependence, whereas when incidence of parasitism or disease is elevated in high host density conditions, it is known as direct host density dependence.
• When low host density causes an increase in incidence of parasitism or disease, this is known as inverse host density dependence, whereas when incidence of parasitism or disease is elevated in high host density conditions, it is known as direct host density dependence.
• When low host density causes an increase in incidence of parasitism or disease, this is known as inverse host density dependence, whereas when incidence of parasitism or disease is elevated in high host density conditions, it is known as direct host density dependence.

• The last column for each year provides the " host density " measured as the number of hosts per 1000 inhabitants; for comparison, consider that the average host density in the world was 43 hosts per 1000 inhabitants in 2007 and 72 hosts per 1000 inhabitants in 2013.
