0 a valley that has a river that is usually dry except when it has rained, common in desert areas of North Africa and Western Asia
Readers will appreciate the thumbnail accounts of tribes and towns and the maps of mountain ranges, plateaus, wadis, and sub-regions with their primary settlements.
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.
