Sentence examples for hosts population from inspiring English sources

We divide the definitive hosts population (mainly the dogs) into three subclasses: the susceptible population, the exposed population, and the infected population, denoted by (S_{1}(t)), (E_{1}(t)), and (I_{1}(t)), respectively, and (N_{1}(t)=S_{1}(t)+E_{1}(t)+I_{1}(t)) is the total number of definitive hosts.

Fixing (tau_{2}=5/12mbox{ year}), we vary (tau_{1}) from (frac{1}{8}) year to (frac{1}{6}) year, and from Figure 1 we see the disease of the intermediate hosts population (I_{2}) persists; as (tau_{1}) increases, the infection level becomes lower.

We divide the intermediate hosts population into three subclasses: the susceptible population ((S_{2}(t))), the exposed population ((E_{2}(t))) and the infected population ((I_{2}(t))), and (N_{2}(t)=S_{2}(t)+E_{2}(t)+I_{2}(t)) is the total number of intermediate hosts.

Results suggest that barriers and fragmented landscapes can restrict or facilitate disease spread or parasite invasion (Blanchong et al. 2008; Su et al. 2008; Vander Wal et al. 2012, 2013a) and modulate potential outbreaks by shaping hosts population structure (Cullingham et al. 2009; Rioux-Paquette et al. 2014).

Vectors and hosts populations are then classically divided into compartments corresponding to their respective disease status.

Parasites have also been used to track inbreeding and the loss of genetic diversity in their hosts' populations.

Large shifts in pathogen virulence relate to host population structure.

It would disappear once it had consumed its host population.

Because the parasite population cannot reproduce itself in such a host population, the entire host population is immune to the epidemic disease, a phenomenon known as herd immunity.

Under such circumstances, and they are not uncommon, the dissemination of the parasite in a host population is dependent not only on the interaction of the parasite population with that of the host population but also on the interaction of the intermediate or vector host population with both parasite and host populations.

Changes in host population sizes can lead to marked shifts in community composition and ecosystem functioning3,4,6.
