How life histories vary in relation to parasite burdens and the specific hazards presented by the contrasting environments in disparate wadis remains to be elucidated. Residents were then returned to their home cage and all cages returned to the room allocated to their wadi. Which tube received the home, neighbouring or distant wadi intruder's sawdust was randomized across residents. The site x infection interaction indicated that the differences in prevalence between the wadis (table 4) were significant. Sixty-eight traps were set in the boulder debris in each wadi at sites identified as active from the presence of fresh faeces and disturbed soil. Population-level comparisons between wadis showed that local differences in the intensity of helminth infection were associated positively with a composite index of androgen activity. Males from each wadi were housed in a separate room on a natural light/dark cycle and at ambient temperature with freely-circulating outside air. There was no significant effect of resident or intruder wadi on the number of entries to tubes. Our second objective was to assess whether the helminth component community structures of small rodent populations living in five disparate wadis differed, particularly with respect to the dominant parasite species. These differences between the wadis may reflect the relative abundance of intermediate hosts and possibly, host intrinsic factors such as genetically determined differences in resistance to parasitic helminths. Significant differences were identified in the abundance of total nematode burdens and the mean helminth species richness between the three wadis which provided multiple captures of mice. Interestingly, no significant relationships emerged between aggression and the helminth burden of individual hosts, either overall or when high and low abundance wadis were analysed separately. First, it is clear from the research done so far that the wadi bottoms in the desert are capable of being farmed. From the Hansard archive Example from the Hansard archive.
