TL;DR: Large numbers of birds, wild mammals and domestic stock from a variety of localities within the Republic of South Africa were examined for infestation with the ixodid ticks Amblyomma hebraeum and Amblyma marmoreum, and most animals examined appeared to be good hosts of the immature stages.
Abstract: Large numbers of birds, wild mammals and domestic stock from a variety of localities within the Republic of South Africa were examined for infestation with the ixodid ticks Amblyomma hebraeum and Amblyomma marmoreum. Every warthog (Phacochoerus aethiopicus), Burchell's zebra (Equus burchelli), impala (Aepyceros melampus) and kudu (Tragelaphus strepsiceros) from the Kruger National Park in the north-eastern Transvaal Lowveld was infested with A. hebraeum. In the eastern Cape Province every helmeted guinea fowl (Numida meleagris), scrub hare (Lepus saxatilis) and kudu from the Andries Vosloo Kudu Reserve; all but 1 of the 22 domestic cattle examined on the farm "Bucklands"; and all Angora goats plus nearly all Boer goats examined on the farm "Brakhill" were infested with this tick. Most animals examined appeared to be good hosts of the immature stages, and the larger the host species the greater the chances of it harbouring large numbers of adult ticks. The largest animals examined, such as eland, buffalo, giraffe and rhinoceros, harboured very large numbers of adult A. hebraeum. No adult A. marmoreum was recovered from any host. However, 50% or more of helmeted guinea fowl and kudu from the Andries Vosloo Kudu Reserve; helmeted guinea fowl, scrub hares and eland (Taurotragus oryx) from the Mountain Zebra National Park; helmeted guinea fowl, kudu, domestic sheep, goats and cattle on the farm "Bucklands", and caracal (Felis caracal) from the Cradock and Southwell areas of the eastern Cape Province were infested with immature A. marmoreum. In the Bontebok National Park in the south-western Cape Province more than 35% of scrub hares, vaal ribbok (Pelea capreolus) and bontebok (Damaliscus dorcas dorcas) were infested with immature ticks.

TL;DR: The four species in the genus Hyalomma that are found in Southern African are illustrated and described, their geographic distributions mapped, their hosts listed, and when available, their life cycles, seasonal abundance and role as vectors of disease are provided.

TL;DR: Six novel, polymorphic microsatellite markers for the scrub hare, Lepus saxatilis, have been developed and will be useful for phylogeographical studies in the scrubHare and other leporidae.
Abstract: We have developed six novel, polymorphic microsatellite markers for the scrub hare, Lepus saxatilis. These markers have been tested for 150 scrub hares and 67 Cape hares from different localities across southern Africa. All six loci amplified consistently well and most were highly polymorphic. Four loci amplified consistently in five different leporid genera. The microsatellites presented here will be useful for phylogeographical studies in the scrub hare and other leporidae.

TL;DR: The infant ticks preferred scrub hares as hosts and were recovered from these animals even when few adult ticks were present on large herbivores in the locality, while the adults were most abundant on Cape mountain zebra and eland during summer.
Abstract: The host preferences of immature and adult Hyalomma marginatum rufipes, Hyalomma marginatum turanicum and Hyalomma truncatum were studied at various localities in the Cape Province. The immature stages of all 3 ticks preferred scrub hares (Lepus saxatilis) as hosts and were recovered from these animals even when few adult ticks were present on large herbivores in the locality. Ground-frequenting birds were also infested, but only with immature H. marginatum rufipes and H. marginatum turanicum. Some small rodents were also infested but only with the immature stages of H. truncatum. The adult ticks preferred Cape mountain zebra (Equus zebra zebra), eland (Taurotragus oryx) and cattle. The immature stages of H. marginatum rufipes were most abundant on scrub hares from February to August. Too few adult ticks of this species were recovered to determine their seasonal abundance. The immature stages of H. marginatum turanicum were most abundant on scrub hares during the winter months and the adults were most abundant on scrub hares during the winter months and the adults were most abundant on Cape mountain zebra and eland during summer. Immature H. truncatum were most abundant on scrub hares during February and May, while peak adult burdens were found on zebra and eland during February, August, November and December.

TL;DR: Mismatch distribution analyses indicated sudden population size expansions in the history of all three populations, and neighbour-joining analysis revealed a pattern that did not correspond to the current subspecies delineations.
Abstract: Genetic differentiation among populations of the South African scrub hare Lepus saxatilis was examined using hypervariable mitochondrial DNA control region I (CR-I) sequences Neighbour-joining analysis revealed a pattern that did not correspond to the current subspecies delineations The CR-I sequence data delimit scrub hares into three major maternal lineages The three phylogenetic assemblages exhibited different geographical distributions AMOVA analyses and exact tests for population differentiation confirmed this phylogeographic partitioning One lineage (SW) was confined to the south-western Cape, the second lineage (N) was exclusively found in the northern part of South Africa and in the neighbouring countries, and the third lineage (C) was predominant in the central parts of South Africa This spatial distribution did not coincide with the ranges of the 10 described subspecies covered by our sampling regime The lineages C and N overlapped in an area including eastern parts of South Africa and southern Namibia The presence of both lineages in that area of overlap was interpreted as the result of secondary contact due to recent range expansions after the two lineages had undergone a population restriction approximately 18 000 years ago Analyses of contemporary gene flow disclosed an exchange of migrants between N and C, which was biased towards a movement from C to N The SW group represents a very distinct evolutionary lineage that has been isolated for more than 45 000 years It does not exchange female migrants with the other two groups Mismatch distribution analyses indicated sudden population size expansions in the history of all three populations
