His team will develop a mathematical model to evaluate the feasibility of starting a vaccine programme aimed at getting rid of chytrid, or at least keeping the infection rate low and thus preventing population declines among existing amphibian species.
"Controlling parasites certainly increases grouse numbers, but might not be sufficient to prevent population declines.
Land use intensification results in economic development but is not enough to prevent population loss and has a negative impact on both the water supply and on aesthetic services.
To prevent population extinction we incorporated a stochastic immigration process that compensated for offspring mortality and reproductive failure.
However, in our hands these methods frequently result in impurities where fibrillar seeds prevent population of oligomers.
Our study shows that generalist predators sometimes occur at high densities on natural willows, which seem to prevent population increase of leaf beetles.
Thirdly, that they come from the same ethnic origin as our DD samples, which is important to prevent population stratification from affecting our association analyses.
The present population-based cohort study of Danish Caucasian men where the controls were randomly selected from the same population in which the cases were identified effectively prevents population stratification.
As such, even 3% survival through a population decline could leave a considerable number of genotypically diverse individuals for population recovery the following year, facilitating the maintenance of high levels of diversity and preventing population differentiation over time.
The case-cohort study design of Danish Caucasian men where the controls were randomly selected from the same population in which the cases were identified effectively prevents population stratification.
