Spatial Dynamics in Fisheries Stock Assessment
... The previous section gave evidence for how an unequal probability of capture for all individuals confounded expectations of Y/R. While that exercise is useful in demonstrating the concept, especially since Y/R is a ...

Mathematical modeling of amoeba-bacteria population dynamics
... The second feature is that the amount of biomass due to the consumption of bacteria by amoebae is redistributed over the total population, which therefore takes advantage of the food ingested by single cells. This ...

The population dynamics of maternal-effect selfish genes.
... The rate of spread when rare is very slow, on the order of the frequency squared pz, but this can be accelerated to order p when there is density regulation at t[r] ...

Mathematical Model for the Population Dynamics of the Serengeti Ecosystem
... Imposing seasonal variation to multispecies models that in a constant environment tend towards a stable equilibrium can lead to cycles and even chaotic dynamics [7], with overcompensating density dependence ...

Fish Population Genetics and Applications of Molecular Markers to Fisheries and Aquaculture: I- Basic Principles of Fish Population Genetics
... The first set ordinarily assumes independent evolution in all branches of the tree, as would be expected for mutation, drift and certain models of variable selection. The second set assumes that the number of mutations ...

Within flock population dynamics of Dichelobacter nodosus
... The discriminatory ability (D) of serogroups, pgr, and MLVA loci and types was calculated as described by Hunter and Gaston (29), e.g., if D = 0.7, there was a 70% probability that two isolates selected at random would ...

Modelling the population dynamics of Ascaris suum in pigs
... In a final analysis, the best fit o f the model to coproprevalence data was obtained by optimising the model parameters. To keep the model as simple as possible, it was assumed that concomitant infections occurred, but ...
