Ví dụ về mortality

• Regarding its implication for premature mortalities, we assume only those experienced by the urban households will be affected.

• The series of concentrations on individual cards was selected to produce a range of mortalities between 5 and 95%.

• Considerably lower mortalities at all temperatures tested were recorded in the pupal stages.

• Daily mortalities of 0%, 0.5%, 1% and 2% were used for adult flies.

• Each week dead snails were removed from the tank and the number of mortalities recorded.

• Ultimately, parasite-induced host mortalities (which are density-dependent) will regulate host and parasite population growth.

• However, in the present experiments, differences in egg-to-larva mortalities between cropping patterns were not significant.

• We find that brick kilns emissions are responsible for serious health damages including over a dozen premature mortalities per year.

• A reference toxicant concentration series (0.5 or higher) should be selected that will consistently provide partial mortalities at two or more concentrations.

• The parasite population is subject to density-dependent constraints imposed by parasite-induced host mortalities and hence will attain an equilibrium state.

• Fish mortalities were recorded along with the dates of their replacement.

• During the exposure period there were no mortalities of the snail hosts.

• Such a high rate of carbohydrate expenditure resulted in large mortalities, especially in infected snails.

• The above results suggest that the pyrethroids are mildly repellent at concentrations of about one tenth of that required to produce detectable mortalities.

• Processes influencing the distribution of parasite numbers within host populations with special emphasis on parasite-induced host mortalities.
