Campuloclinium macrocephalum is native to Central and South America, but is a highly invasive weed in South Africa, where it is commonly known as the 'pompom weed'. It is targeted for biological control, the success of which will depend on host specificity and biotype compatibility to its full genetic diversity in South Africa. We investigated the genetic diversity and phylogeography of 52 specimens from across South Africa, 14 from Argentina and three from Brazil using nuclear ribosomal ITS regions. We further explored the AFLP marker diversity in 54 South African, 25 Argentine and three Brazilian specimens. Maximum parsimony analysis of the ITS sequence data produced an unresolved phylogeny. However, three haplotypes were recognised via network analysis. All South African, one Brazilian and all bar one of the Argentine individuals shared a single haplotype. AFLP analyses generated two genetic clusters with a low net nucleotide distance of 0.115 and further revealed that most plants were a mixture of alleles from these two genetic clusters. Although there was a significant genetic variation among the populations, genetic differentiation and mean heterozygosity were low, suggesting that clonal reproduction may be occurring. The current South African populations may therefore be clonal products with different proportions of genetic admixture introduced more than once. The original point of entry appears to be Gauteng, South Africa. Long-distance dispersal appears to have played a major role in its spread across South Africa. Candidate Argentine biological control agents should therefore be effective on C. macrocephalum in South Africa.
Global contraceptive use is at 64%, Africa lagging behind at 33.4%. Kenya has an unmet need for family planning at 23%. Hormonal injections are the most used in Africa at 9.8% and Intra-Uterine Contraceptive Devices at 3.8%. Low uptake of 3.4% was reported in Meru Hospital and lack of literature on immediate Post Partum Intra Uterine Contraceptive Device (PPIUCD) uptake. Immediate Post Partum Intra Uterine Contraceptive Device is a long acting reversible contraceptive device inserted into the uterus immediately within 48 hours after delivery. The objective was to assess Barriers to Immediate Post-Partum Intra-Uterine Contraceptive Device uptake among Mothers delivering in Meru Hospital. Descriptive research design was used and a population of 289 mothers was targeted. Sample size of 74 respondents was selected using simple random sampling. Questionnaires and interview schedules were used to collect data. The collected data were entered and analyzed using Statistical Package for Social Science windows version 23.0. Descriptive analysis was used to obtain frequencies and percentages. Chi-square was used to test the relationship of study variables and presented in tables. The qualitative data were analyzed thematically. The findings revealed that provider related barriers such as none provision of the services and untimely counseling for the insertion had the highest impact to low uptake (57%). Clients lacked information where 68% reported that they were not counseled. Demographic and reproductive characteristics also played a role in low uptake. Using the chi square test, there was a significant relationship, P = 0.001 between young age of the mothers, unemployment (53%), low parity (56%) and low uptake. Preference for other alternative contraceptives (25.8%) such as hormonal methods was a barrier to the uptake. Therefore, barriers to PPIUCD uptake are provider related, alternative methods of contraception and client related such as lack of information, unemployment, young age and low parity.
Campuloclinium macrocephalum (Less.) DC. (Asteraceae) is a perennial herb native to Central and South America (Goodall, 2016). It was first reported in South Africa in the early 1960s and was likely introduced either as an ornamental or through contaminated hay (McConnachie et al., 2011). Genetic evidence suggests that the pompom invasion may have resulted from multiple introductions mainly through Gauteng province in South Africa, with long-distance dispersal playing a major role in its spread across the country (Gitonga
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
