Sentence examples for host expansion from inspiring English sources

Better knowledge of this zone is relevant, given the recent host expansion of mountain pine beetle into jack pine.

This work has addressed hypotheses connecting gall-thrips phylogeny with host-plant evolution and suggests that host expansion and climate change have important consequences for gall-thrips diversification.

The recent emergence, host expansion, and spread of a highly pathogenic avian influenza (HPAI) H5N1 subtype in Asia have heightened concerns globally, both in regards to mortality from HPAI H5N1 infection in humans and the potential of a new pandemic.

Our study demonstrated that HTNV not only infects its traditional host, the striped mouse, but also infects house mice and rats; SEOV infects not only rats but also shrews, suggesting host expansion for both HTNV and SEOV in China.

The high sequence conservation between C. parvum and C. hominis genomes and significant differences in copy numbers of MEDLE family secreted proteins and insulinase-like proteases indicate that telomeric gene duplications could potentially contribute to host expansion in C. parvum.

As sequence differences in non-coding regulatory elements can also affect the timing or expression levels of invasion-associated proteins, more studies are needed to determine whether the duplications of MEDLE and insulinase genes are indeed the cause of the host expansion of in C. parvum.

As colonizations of novel plants are typically associated with host expansions such diversity is likely to have been caused by historical polyphagy [ 12].

Virtually all documented host plant colonizations in that study led to host expansions, not to direct host shifts, and the evolutionary trend in this group was actually towards increased generalization rather than specialization.

Even if specialization is a pervasive pattern, the process is not irreversible and occasional episodes of host expansions could conceivably generate the necessary variation in host use to drive speciation.

The most likely mechanism by which host expansions can increase the likelihood of speciation is that they allow the insect to gain a wider geographic distribution [ 50] and thus put it in a situation where genetic fragmentation is more likely.

The two populations also shared several haplotypes for all genes analysed suggesting that the switch to potatoes resulted in a large founder population and/or multiple host expansions occurred.
