TL;DR: In this article, the ecology of wildlife diseases is studied and the role of tick-borne infections in wildlife reservoirs is discussed. But the focus of this paper is not on the transmission and persistence of macroparasite infections.
Abstract: 1: Ecology of wildlife diseases. 2: Heterogeneities in macroparasite infections: patterns and processes. 3: Parasites and host population dynamics. 4: Parasite community ecology and biodiversity. 5: Microparasite transmission and persistence. 6: Spatial aspects of disease dynamics. 7: The ecology of tick-borne infections in wildlife reservoirs. 8: The role of pathogens in biological conservation. 9: Visions for future research in wildlife epidemiology

TL;DR: Using a relatively new technique for parasitological infection data - tree-based models, as well as traditional linear models - a number of the parasitic infections was found to be associated with systematically lower or higher parasite burdens.
Abstract: In this paper we review the published literature on patterns of abundance and aggregation of macroparasites in wildlife host populations. We base this survey on quantitative analyses of mean burden and a number of measures of the degree of aggregation of parasite burdens between hosts. All major parasite and vertebrate host taxa were represented in the database. Mean parasite burden was found to be log-normally distributed, indicating that all parasite burdens are regulated to some degree. In addition, all but one of the parasitic infections were aggregated with respect to their hosts, and the relationship between log mean parasite burden and log variance was found to be very strong (R2 = 0·87). That is, for a given mean parasite burden there are constraints on the degree of variation in individual host burdens. The aggregated nature of the parasitic infections is also apparent from other measures of the degree of aggregation: prevalence – mean relationships, and the negative binomial parameter, k. Using a relatively new technique for parasitological infection data – tree-based models, as well as traditional linear models – a number of the parasitic infections was found to be associated with systematically lower or higher parasite burdens. Possible biological explanations for these and other patterns are proposed.

TL;DR: In this paper, the authors used data on communities of gastrointestinal strongylid nematodes from 19 mammalian species, representing examination of 6670 individual hosts, and studied both the average abundance of all strong-lid worms within a host species, and the two components of abundance, prevalence and intensity.
Abstract: Several epidemiological models predict a positive relationship between host population density and abundance of directly transmitted macroparasites. Here, we generalize these, and test the prediction by a comparative study. We used data on communities of gastrointestinal strongylid nematodes from 19 mammalian species, representing examination of 6670 individual hosts. We studied both the average abundance of all strongylid nematodes within a host species, and the two components of abundance, prevalence and intensity. The effects of host body weight, diet, fecundity and age at maturity and parasite body size were controlled for directly, and the phylogenetically independent contrast method was used to control for confounding factors more generally. Host population density and average parasite abundance were strongly positively correlated within mammalian taxa, and across all species when the effects of host body weight were controlled for. Controlling for other variables did not change this. Even when looking at single parasite species occurring in several host species, abundance was highest in the host species with the highest population density. Prevalence and intensity showed similar patterns. These patterns provide the first macroecological evidence consistent with the prediction that transmission rates depend on host population density in natural parasite communities.
