| factors affecting the seasonal abundance of ground squirrel and wood rat fleas (siphonaptera) in san diego county, california. | abiotic and biotic factors affecting the seasonal abundance of 3 species of sylvatic fleas on their hosts were examined at 7 sites in san diego county, california. indices for oropsylla (diamanus) montana (baker) were usually highest on spermophilus beecheyi nudipes (huey) when < 18.4 degrees c (october-december), whereas those for hoplopsyllus anomalus (baker) were highest when > 18.4 degrees c (july-september). o. montana was affected most by ambient temperature (inversely for the coastal site ... | 1996 | 8840686 |
| mammal and flea relationships in the great basin desert: from h. j. egoscue's collections. | host-parasite association among 58 flea species parasitizing 40 mammal species in the great basin desert of the western united states was investigated. increased flea species richness was correlated with larger geographic ranges and stable locomotion of hosts. hosts from habitats of moderately low productivity (sage and grass) and of peromyscus maniculatus size, 10-33 g, had the highest flea species richness. larger hosts had fewer flea species, but fleas were more prevalent. increased host spec ... | 2006 | 16729681 |
