Bats (Order Chiroptera), the only mammals capable of powered flight and sophisticated laryngeal echolocation, represent one most species-rich ubiquitous orders mammals. However, phylogenetic relationships within this group are poorly resolved. A robust evolutionary tree Chiroptera is essential for evaluating phylogeny echolocation Chiroptera, as well understanding their biogeographical history. We generated 4 kb sequence data from portions four novel nuclear intron markers multiple...

The hares and rabbits belonging to the family Leporidae have a nearly worldwide distribution approximately 72% of genera geographically restricted distributions. Despite several attempts using morphological, cytogenetic, mitochondrial DNA evidence, robust phylogeny for remains elusive. To provide phylogenetic resolution within this group, molecular supermatrix was constructed 27 taxa representing all 11 leporid genera. Five nuclear (SPTBN1, PRKCI, THY, TG, MGF) two (cytochrome b 12S rRNA)...

A total of 7,806 nucleotide positions derived from one mitochondrial and eight nuclear DNA segments were used to provide a robust phylogeny for members the order Artiodactyla. Twenty-four artiodactyl two cetacean species included, horse (order Perissodactyla) was as outgroup. Limited rate heterogeneity observed among genes. The partition homogeneity tests indicated no conflicting signal genes fragments, so sequence data analyzed together separate loci. Analyses based on individual fragments...

The evolutionary history of the family Bovidae remains controversial despite past comprehensive morphological and genetic investigations. In an effort to resolve some systematic uncertainties within group, a combined molecular phylogeny was constructed based on four independent nuclear DNA markers (2,573 characters) three mitochondrial genes (1,690 for 34 bovid taxa representing all seven currently recognized subfamilies. fragments were analyzed separately in combination after partition...

Abstract The southern African landscape appears to have experienced frequent shifts in vegetation associated with climatic change through the mid‐Miocene and Plio–Pleistocene. One group whose historical biogeography may been affected by these fluctuations are dwarf chameleons ( Bradypodion ), due their associations distinct types. Thus, this provides an opportunity investigate light of fluctuations. A total 138 from Cape Floristic Region South Africa were sequenced for two mitochondrial...

Aim East Africa is one of the most biologically diverse regions, especially in terms endemism and species richness. Hypotheses put forward to explain this high diversity invoke a role for forest refugia through: (1) accumulation new due radiation within refugial habitats, or (2) retention older palaeoendemic stable refugia. We tested these alternative hypotheses using data genus African chameleons, Kinyongia. Location Africa. Methods constructed dated phylogeny Kinyongia nuclear two...

Abstract Aim Isolation by distance ( IBD ) analyses are an effective tool for determining genetic connectivity among populations, providing a basis estimating dispersal and thus contributing to spatial biodiversity planning. Here, we use approach determine patterns of infer distances phylogenetically diverse range marine species. Location Two thousand eight hundred kilometre South African coastline. Methods mt DNA data sets 11 rocky shore reef‐dwelling species with life history strategies...

Abstract Aim Climate change is expected to drive range shifts among a wide array of organisms. Non‐indigenous species ( NIS ) provide unique opportunity observe the establishment boundaries in way that cannot be directly seen for native species. Recent studies have indicated climate facilitates biological invasions at local scales. However, generality these effects unclear, as there dearth comparative assess how rapid environmental affects ranges across taxa and biogeographic provinces....

The number of rodent clades identified above the family level is contentious, and to date, no consensus has been reached on basal evolutionary relationships among all families. Rodent suprafamilial phylogenetic are investigated in present study using ~7600 nucleotide characters derived from two mitochondrial genes (Cytochrome b 12S rRNA), nuclear exons (IRBP vWF) four introns (MGF, PRKC, SPTBN, THY). Because increasing nucleotides does not necessarily increase signal (especially if data...

Abstract Background Oceanography and life-history characteristics are known to influence the genetic structure of marine species, however relative role that these factors play in shaping phylogeographic patterns remains unresolved. The population endemic, rocky shore dwelling Caffrogobius caffer was investigated across a major oceanographic barrier, Cape Agulhas, which has previously been shown strongly structuring South African intertidal organisms. Given variable dynamic oceanographical...

Mislabelling poses a threat to sustainability seafood supply chains and, when frequent, can significantly affect conservation efforts. Here we identify most popular African market through consumer retailer surveys data gathered by sustainable campaign. Of these species,...

Abstract Parasites and hosts interact across both micro‐ macroevolutionary scales where congruence among their phylogeographic phylogenetic structures may be observed. Within southern A frica, the four‐striped mouse genus, R habdomys , is parasitized by ectoparasitic sucking louse, P olyplax arvicanthis . Molecular data recently suggested presence of two cryptic species within that are sympatrically distributed distributions four putative species. We tested hypotheses cophylogeny parasite...
