Measuring aggregation in parasite populations
TLDR
The definition that parasite–host system A is more aggregated than parasite– host system B if any givenportion of the parasite population is concentrated in a smaller proportion of the host population A than of host population B is used.
Estimating the relationship between abundance and distribution
TLDR
Using simulations and ana- lytical derivations, it is examined whether indices reflecting one of the three aspects of distribution, proportion of area occupied, aggregation, and geographical range, provide unbiased estimates of the relationship when estimated from count data.
Explaining variability in parasite aggregation levels among host samples
TLDR
The strong relationship between aggregation levels andmean infection levels indicated that aggregation levels are tightly constrained by mean infection levels, and that only a small proportion of the observed variability in parasite aggregation levels remains to be accounted for by other factors.
Modelling macroparasite aggregation using a nematode-sheep system: the Weibull distribution as an alternative to the Negative Binomial distribution?
TLDR
It is found that the NBD is seldom the best fit for gastrointestinal nematode distributions, and the Weibull distribution was clearly more appropriate over a very wide range of degrees of aggregation, mainly because it was more flexible in fitting the heavily infected hosts.
On the interpretation of age–intensity profiles and dispersion patterns in parasitological surveys
TLDR
It is shown that the interpretation of observed patterns can be ambiguous if more than 1 process takes place, and underline that age–intensity profiles should be interpreted on the basis of available a priori knowledge about the processes assumed to be involved.
Chapter 2 : Heterogeneities in macroparasite infections : patterns and processes 1
TLDR
What is unclear at present, is the relative significance of these different mechanisms, and the importance of interactions between mechanisms in accentuating individual differences in parasite loads.
The evolution of parasite manipulation of host behaviour: a theoretical analysis.
TLDR
This evolutionary analysis indicates that ecological and life history variables may have played an important role in the evolution of manipulation of host behaviour by parasites.
Distribution and abundance of parasite nematodes: ecological specialisation, phylogenetic constraint or simply epidemiology?
TLDR
Both the bimodal distribution of parasite prevalence and the mean-variance power function simply result from demographic and stochastic patterns (highlighted by the sampling model), which present compelling evidence that nematode parasite species might adjust their spatial distribution and burden in mammal hosts for simple epidemiological reasons.

Temporal changes in aggregation: a laboratory study.
TLDR
It is suggested that the variance to mean ratio is a better measure when the prevalence and/or mean burden are changing and when the tail of the distribution is of particular interest, and that k may be a preferred parameter when the zero class or the lightly infected hosts are of primary interest.
Processes influencing the distribution of parasite numbers within host populations with special emphasis on parasite-induced host mortalities.
TLDR
It is shown that, for certain types of host-parasite associations, convex curves of mean parasite abundance in relation to age (age-intensity curves), concomitant with a decline in the degree of dispersion in the older age, classes of hosts, may be evidence of the induction in host mortality by parasite infection.
FITTING THE NEGATIVE BINOMIAL DISTRIBUTION TO BIOLOGICAL DATA AND NOTE ON THE EFFICIENT FITTING OF THE NEGATIVE BINOMIAL
TLDR
Over dispersion is called "over dispersion" for series in which the variance is significantly larger than the mean, not only in distributions of plants and animals in nature but even in the laboratory.
A quantitative approach to parasitism.
TLDR
From the overdispersed frequency distributions exemplified by the Negative Binomial distribution a specially truncated form is derived and shown to fit the data of Hynes & Nicholas (1963) and these form the basis of a definition of parasitism.
Patterns of distribution of the tick Ixodes trianguliceps Birula on its hosts
TLDR
During a three-year study of the ecological relationship between the tick, Ixodes trianguliceps Birula 1895, and its small mammal hosts, the tick infestation patterns were analysed and reflected the biological factors working within the host-parasite interaction.
Inequalities in the individual reproductive success of parasites.
TLDR
The analysis suggests that both population density and host nutrition are important in determining the observed degree of inequality in reproductive success and body size.
Individual variability in reproductive success of Triaenophorus crassus Forel (Cestoda: Pseudophyllidea), with comments on use of the Lorenz curve and Gini coefficient
TLDR
Inequalities in worm mass did not provide an accurate estimate of inequalities in reproductive success but could be used as an indirect index for comparative purposes and can potentially modify parasite transmission.
The potential of parasitism in the structuring of a salt marsh stickleback community
TLDR
To determine if ectoparasites have the potential to play a role in structuring a salt marsh stickleback community, abundance of the copepod Thersitina gasterostei and fish louse Argulus canadensis was measured, and their effects on the condition and survival of juvenile fish were quantified.
Prevalence and abundance of helminth parasites in an intensively fished population of brook trout (Salvelinus fontinalis) at a small subarctic lake
TLDR
The fish catch in the first year was dominated by the 3+ year class and older fish, whereas by the second year 1+ and 2+ fish were proportionately more abundant, and the importance of older cohorts declined.
