Three hypotheses were formulated on the relationship between habitat connectivity, as a prerequisite for genetic exchange, and habitat aggregation and contrast between habitat types.
Multiple infection of a host may also directly affect the genetic diversity of the pathogen population, as co-infection is a prerequisite for genetic exchange between different pathogen species or strains.
Nevertheless, in theory present contact should not be a prerequisite for gene exchange; given that species have most likely suffered repeated pulses of range expansions and contractions due to geological or climatic events, presently allopatric pairs of species may have met at some point in their past and then hybridized.
The saccular stage is marked by a dramatic improvement of the prerequisites for gas exchange, and any derangement of this vulnerable period will lead to relevant limitations of gas exchange.
We hear little of the political ideals of equality and individual liberty, usually considered prerequisites for both exchange and innovation.
"Opening" the liquid-filled lung directly after birth in order to increase inspiratory volume and functional residual capacity (FRC) is a prerequisite for sufficient gas exchange.
An understanding of the genetic determinism of photoperiod response of flowering is a prerequisite for the successful exchange of germplasm across different latitudes.
A prerequisite for such data exchange is a transformation of ODM data structures into CDA and vice versa.
J.T.: I viewed this as a great opportunity to experience the DPRK as a resident, and also to help build a positive and trusting relationship with people in the DPRK, a necessary prerequisite for some future scientific exchanges.
Therefore, it is a theoretical prerequisite for market development that market exchange be separated from various types of personal relationships and authority structures.
Similarly, in outcrossing species, synchronized flowering of conspecifics ensures that pollen can be exchanged, a prerequisite for fertilization.
