reproductive interactions between two australian reptile tick species. | in south australia the two tick species amblyomma limbatum and aponomma hydrosauri share the same common reptile host species, but have allopatric distributions which abut along a narrow parapatric boundary. reproductive interference is a mechanism that has previously been suggested could contribute to maintaining the boundary. populations of each species were established in pens within the range of aponomma hydrosauri. pens held either each species alone, or the two species together. the perfor ... | 1994 | 7628259 |
influence of temperature and relative humidity on the moulting success of amblyomma limbatum and aponomma hydrosauri (acari: ixodidae) larvae and nymphs. | this study compared the duration of the moulting periods of engorged larvae and nymphs of the ixodid ticks, amblyomma limbatum and aponomma hydrosauri, at different temperature/relative humidity regimes, and examined the relationships between the engorged weight of ticks and their weights after moulting. the results showed that for each species, there was a significant relationship between the weights of unfed nymphs and engorged larvae, and the weights of unfed adults and engorged nymphs. the w ... | 2000 | 10980285 |
temporal and spatial dynamics of a parapatric boundary between two australian reptile ticks. | two tick species aponomma hydrosauri and amblyomma limbatum that infest large reptiles have an abrupt parapatric boundary near mt mary in south australia. a previous model has suggested that the boundary is maintained at population density troughs resulting from habitat heterogeneity along a gradual environmental gradient. this paper describes the dynamics of the boundary on three transects over 17 years, 1982-98. over the last seven years of that period there has been a significant increase in ... | 2001 | 11298975 |
a new focus of rickettsia honei spotted fever in south australia. | we recently diagnosed rickettsial spotted fever in four patients from the south-eastern coastal region of south australia near adelaide, an area not known to be endemic for this infection. all infections were acquired within the geographic range of aponomma hydrosauri, the tick vector of rickettsia honei. infection by r. honei was confirmed in two patients. this extension of the known geographic range of r. honei infection may be explained, in part, by alterations in host-parasite ecology. | 2005 | 15748134 |
not only 'flinders island' spotted fever. | to demonstrate that flinders island spotted fever (fisf), a spotted fever group rickettsial infection caused by rickettsia honei, is found not only on flinders island (bass strait), tasmania, but elsewhere in south-east australia. | 2005 | 16175900 |
