Flo Nozoil helps relieve dry and crusting nasal tissue. Your healthcare practitioner may recommend Nozoil in the following situations: Graduate Student (Supervisors: Steve Compton (University of Leeds), Prof R K Butlin, Roger Key (English Nature)

Whether we view polyploid speciation as ecological or nonecological is largely a semantic argument. If we recognize a polyploid as a new species at the time of its origin, regardless of its ability to persist, then polyploid speciation is nonecological. If instead, polyploids are regarded as new species only if they can establish a self-sustaining population that is reproductively isolated from its progenitor, then polyploid speciation is often ecological.

Can Flo Nozoil can be used in pregnancy and while breastfeeding?

Sometimes dryness and crusting in the nose may result in bleeding. If the bleeding is severe, consult your healthcare practitioner. Divergent pollinator-selected style lengths in Mimulus cardinalis and M. lewisii lead to differentiated pollen tube lengths, reducing the amount of expected hybridization in mixed pollinations.
