“…A. senegal (L.) Willd is a leguminous multipurpose species belonging to the subgenus Aculeiferum (Arce and Blanks, 2001). The international botanical community accepts the retypifying Acacia with a new type which would place most species ascribed to the present subgenus Aculeiferum into the genus Senegalia (Boatwright et al, 2014;Kyalangalilwa et al, 2013;Haddad, 2011).…”

The genetic diversity of African forest resources is poorly documented while it can be the basis for adapting these resources to climatic variations. This study aimed to characterize the genetic diversity of the Acacia senegal (L.) Willd in its natural range in Niger. 252 individuals from 10 populations of the species, across three gum basins were analyzed with 9 nuclear microsatellite markers. Genetic diversity indexes are high in all the populations studied: number of allele (Na) varies from 4.00 to 5.44; allele richness (R) varies from 3.42 to 4.49; observed heterozygosity (Ho) and expected heterozygosity (He) range from 0.44 to 0.56 and from 0.46 to 0.63, respectively. The values of differentiation index (Fst) per pair of population range from 0.0057 to 0.110 and 20% of these values are not significant indicating a low differentiation between populations. In addition, molecular variance analysis shows that 93% of total variation is within populations. Through Bayesian model, a structure of population into three groups is observed. These results could form the basis for building sustainable management and conservation strategies of genetic resources of A. senegal in Niger.

“…Their refusal in stringent specificity tests to feed and oviposit on the native African acacias (then also classified in the genus Acacia) was an early indication that the Australian and African acacias are not closely related. This was confirmed 20 years later by several phylogenetic studies (e.g., Miller et al, 2003;Miller & Seigler, 2012), resulting in the placement of the African acacias into different genera (Senegalia and Vachellia) (e.g., Kyalangalilwa et al, 2013). The seeds of these genera are also utilised by spermophagous beetles, but by an entirely different group, the subfamily Bruchinae of Chrysomelidae (e.g., Kergoat et al, 2005Kergoat et al, , 2011Delobel & Le Ru, 2015;Yirgu, 2016).…”

AbstractThis paper presents the results of a three-year collecting and research project on Melanterius weevils in Australia, aimed mainly at discovering new host associations and assessing their fit to the emerging reconstruction of phylogenetic relationships in the large genus Acacia. A revised and extended diagnosis of the genus Melanterius is provided, as well as characters differentiating the genus from related and/or similar Australian genera classified in the tribe Cleogonini. Given the size (79 species) and morphological variation of Melanterius, and to facilitate the assessment of co-evolutionary patterns between the weevils and their hosts, the genus is divided into six tentative species groups characterised by particular morphological traits. New host and locality data are recorded for 23 species, including five species described as new to science, M. abbreviatus sp. n., M. curvistriatus sp. n., M. psittacoides sp. n., M. pungalinae sp. n. and M. tesseymani sp. n. For each species, salient characters and a summary of known host plant species are provided. Melanterius tasmaniensis (Lea, 1909) comb. et stat. n. is raised from a subspecies of Melanteriosoma costatum to species level. All recorded host associations of Melanterius known to us are summarised, including those published, those recorded on label data associated with specimens in the Australian National Insect Collection and those recorded during this study. These host records are differentiated into true host associations (based on specimens reared from seeds), putative associations (based on long series of specimens collected from plants) and coincidental associations (based on single specimens collected from PINZÓN-NAVARRO ET AL.4 · Zootaxa 4298 (1) © 2017 Magnolia Press plants). Altogether, Melanterius weevils are recorded from 71 species of Acacia, still a small number in view of the ca. 1000 described species of Acacia, but it is likely that many or most of the other species are also hosts of Melanterius species or of the closely related genus Lybaeba. The pattern of host associations in evidence indicates that most species of Melanterius are not host-specific, developing in the seeds of a number of apparently related Acacia species. Nevertheless, several Melanterius species appear to have the potential to be employed as biocontrol agents if their main hosts become invasive weeds.

“…For more than a decade, South African researchers have been among the global leaders in the DNA barcoding, molecular systematics, and community phylogenetics of plants (Kyalangalilwa et al 2013;Charles-Dominique et al 2016;Daru et al 2016;Bezeng et al 2017). This strength is again apparent at the 7th Conference, in which abstracts about plants of Africa feature prominently, alongside other plant-focused contributions from around the globe.…”

Participants in the 7th International Barcode of Life Conference (Kruger National Park, South Africa, 20-24 November 2017) share the latest findings in DNA barcoding research and its increasingly diversified applications. Here, we review prevailing trends synthesized from among 429 invited and contributed abstracts, which are collated in this open-access special issue of Genome. Hosted for the first time on the African continent, the 7th Conference places special emphasis on the evolutionary origins, biogeography, and conservation of African flora and fauna. Within Africa and elsewhere, DNA barcoding and related techniques are being increasingly used for wildlife forensics and for the validation of commercial products, such as medicinal plants and seafood species. A striking trend of the conference is the dramatic rise of studies on environmental DNA (eDNA) and on diverse uses of high-throughput sequencing techniques. Emerging techniques in these areas are opening new avenues for environmental biomonitoring, managing species-at-risk and invasive species, and revealing species interaction networks in unprecedented detail. Contributors call for the development of validated community standards for high-throughput sequence data generation and analysis, to enable the full potential of these methods to be realized for understanding and managing biodiversity on a global scale.
