Positive co-occurrence of flea infestation at a low biological cost in two rodent hosts in the Canary archipelago
SUMMARY Non-random assemblages have been described as a common pattern of flea co-occurrence across mainland host species. However, to date, patterns of flea co-occurrence on islands are unknown. The present work investigates, on one hand, whether the decrease in the number of species on islands aff...

Results supported aggregation of flea species in Mus but not in Rattus , probably due to the relationship between abundance and both prevalence and intensity of infection of the main flea species parasitizing Mus . In addition, heavy individuals of both rodent species showed the highest flea burdens as well as higher species richness, probably due to the continued accumulation of fleas throughout life and/or immunological resistance mechanisms.

SUMMARY Non-random assemblages have been described as a common pattern of flea co-occurrence across mainland host species. However, to date, patterns of flea co-occurrence on islands are unknown.
