“…Moreover, phenotypic or morphological characters and molecular markers may or may not concordantly indicate evolutionary divergence between subspecies or species (e.g., Bonhomme, et al[32] Palacios[3], Alves et al[8,16], Melo-Ferreira et al[10], for hares from the Iberian Peninsula; Palacios[4], Pierpaoli et al[33], Riga et al[34], for L . corsicanus and L .…”

Mitochondrial and nuclear DNA reveals reticulate evolution in hares (Lepus spp., Lagomorpha, Mammalia) from Ethiopia

et al. 2017

For hares (Lepus spp., Leporidae, Lagomorpha, Mammalia) from Ethiopia no conclusive molecular phylogenetic data are available. To provide a first molecular phylogenetic model for the Abyssinian Hare (Lepus habessinicus), the Ethiopian Hare (L. fagani), and the Ethiopian Highland Hare (L. starcki) and their evolutionary relationships to hares from Africa, Eurasia, and North America, we phylogenetically analysed mitochondrial ATPase subunit 6 (ATP6; n = 153 / 416bp) and nuclear transferrin (TF; n = 155 / 434bp) sequences of phenotypically determined individuals. For the hares from Ethiopia, genotype composition at twelve microsatellite loci (n = 107) was used to explore both interspecific gene pool separation and levels of current hybridization, as has been observed in some other Lepus species. For phylogenetic analyses ATP6 and TF sequences of Lepus species from South and North Africa (L. capensis, L. saxatilis), the Anatolian peninsula and Europe (L. europaeus, L. timidus) were also produced and additional TF sequences of 18 Lepus species retrieved from GenBank were included as well. Median joining networks, neighbour joining, maximum likelihood analyses, as well as Bayesian inference resulted in similar models of evolution of the three species from Ethiopia for the ATP6 and TF sequences, respectively. The Ethiopian species are, however, not monophyletic, with signatures of contemporary uni- and bidirectional mitochondrial introgression and/ or shared ancestral polymorphism. Lepus habessinicus carries mtDNA distinct from South African L. capensis and North African L. capensis sensu lato; that finding is not in line with earlier suggestions of its conspecificity with L. capensis. Lepus starcki has mtDNA distinct from L. capensis and L. europaeus, which is not in line with earlier suggestions to include it either in L. capensis or L. europaeus. Lepus fagani shares mitochondrial haplotypes with the other two species from Ethiopia, despite its distinct phenotypic and microsatellite differences; moreover, it is not represented by a species-specific mitochondrial haplogroup, suggesting considerable mitochondrial capture by the other species from Ethiopia or species from other parts of Africa. Both mitochondrial and nuclear sequences indicate close phylogenetic relationships among all three Lepus species from Ethiopia, with L. fagani being surprisingly tightly connected to L. habessinicus. TF sequences suggest close evolutionary relationships between the three Ethiopian species and Cape hares from South and North Africa; they further suggest that hares from Ethiopia hold a position ancestral to many Eurasian and North American species.

“…Previous studies have used discriminant analysis to predict group membership based on similarities between morphological characters (e.g. Senturia, 1995; Reig, Daniels & Macdonald, 2001; Riga et al ., 2001). In our study, we allowed for phylogenetic non‐independence among our data in the following manner.…”

Our understanding of the critical shift in life history among insect parasitoids from ectoparasitism to endoparasitism is hindered by the fact that this particular life history trait is not known for many phylogenetically important taxa. One method of coping with this problem is to seek correlations between the ovipositor structure and this life history trait among taxa whose life history is known, and then to use this to infer the trait in species whose life history in unknown. In one group of parasitoid wasps, the Ichneumonoidea (Hymenoptera), we scored a total of 20 morphometric and morphological characters of the ovipositor for 41 species whose life histories are known -representing all the main clades in which there have been independent transitions to endoparasitism plus a broad range of the ectoparasitoid groups; we then used phylogenetic regression and discriminant analyses to infer the life history of four species whose life histories are unknown. To allow for the effect of phylogenetic non-independence in the discriminant analysis, we carried out analyses using different randomly chosen representatives of the endoparasitoid clades (phylogenetic regression controls for phylogeny). These two methods gave congruent results from which we conclude that Megalohelcon and Gnamptodon are endoparasitoids, and Aspilodemon and Allobracon are ectoparasitoids. We discuss the consequences of these inferences for our understanding of the evolution of endoparasitism in the Ichneumonoidea.

“…In the case of leporids, significantly larger females have been noted in some, but not all taxa (Ralls 1976;Nowak 1999;Riga et al 2001;Davis and Roth 2008). Davis and Roth (2008) measured skeletal elements of many species of Sylvilagus and found that dimorphism is apparent in smaller bodied taxa, and also in one of the three Lepus species that they measured.…”

Forelimb anatomy ofSerengetilagus praecapensis(Mammalia: Lagomorpha): a Pliocene leporid from Laetoli, Tanzania

The forelimb elements of the leporid Serengetilagus praecapensis, from the famous Laetoli sites in Tanzania, occur in three stratigraphic levels. Most come from the Upper Laetolil Beds, the middle unit. Size frequency distributions of limb dimensions demonstrate one highly variable population with no clear trends through time. Statistical analyses cannot be used to support the presence of more than one species. Sexual dimorphism also is not apparent in the samples, but may have contributed to the variability in sizes. Anatomical traits of the forelimb ally Serengetilagus praecapensis with smaller, less cursorial leporids like the modern European rabbit Oryctolagus. Serengetilagus praecapensis has a predicted body mass in the range of 1.2-1.6 kg. Like some smaller modern rabbits, its forelimb suggests the capability for burrowing.
