Species-specific or assemblage-wide decline? The case of Arthroleptides dutoiti Loveridge, 1935 and the amphibian assemblage of Mount Elgon, Kenya

The frog Arthroleptides dutoiti Loveridge, 1935, endemic to Mount Elgon, East Africa was last collected in 1962 and has not been observed since. The species is regarded as Critically Endangered by the IUCN Red List and is a priority species on the Zoological Society of London’s EDGE (Evolutionarily Distinct, Globally Endangered) project, given its Red List status and phylogenetic distinctiveness. We analyse temporal patterns of abundance (1934–2014) of A. dutoiti and the remainder of the Mount Elgon amphibian assemblage to infer the probability of re-encountering A. dutoiti and assess whether declines are species specific to A. dutoiti, or whether they are assemblage-wide phenomena. Our results show that for localities where surveys have been repeatedly conducted, A. dutoiti is likely to be locally extinct. Declines are observed in other Mount Elgon amphibians, encompassing both specialists and generalists. Causal factors for declines are unknown, but habitat change might be important, given the high degree of forest loss in the area, especially since the turn of the 20th century. Urgent sampling of preferred microhabitats of A. dutoiti at the type locality and surrounding areas beyond those included in our study are required to determine whether or not the species is extinct. Impacts on other taxonomic groups would also be useful to understand so that it can be determined how broad the changes are for the Mount Elgon biota

Role of Credit Reference Bureau in Influencing Customer Repayment Behaviour in Mitigating against Credit Default among Commercial Banks in Kenya

The study examined the role of Credit Reference Bureau (CRB) in influencing customer repayment behaviour in militating against credit default in commercial banks in Kenya. The study was based on the Information asymmetry theory Theory. The study used a Causal-Comparative descriptive survey design in evaluating the role of CRB in influencing customer repayment behaviour in mitigating against credit default in commercial banks in Kenya. The target population of the study consisted of all the 43 licensed commercial banks in Kenya under the Banking Act. The researcher used a census of all the 43 commercial banks in Kenya. Primary data was collected using questionnaires. Secondary data was obtained from CBK loan books and CBK annual Bank supervisory reports. Data was analysed using SPSS and results presented using graphs and tables .The researcher used descriptive statistics and inferential statistics. Inferential statistics comprised correlation, regression and Chi-square. The conclusion was that CRB plays a significant role in customer repayment behaviour in Mitigating against credit default in commercial banks in Kenya

Systematics of Hyperolius mitchelli Loveridge, 1953 and Hyperolius rubrovermiculatus Schiøtz, 1975 (Anura: Hyperoliidae) and assignment of populations from northern Tanzania (advance online)

The taxonomic validity of the East African reed frogs Hyperolius mitchelli Loveridge, 1953 and Hyperolius rubrovermiculatus Schiøtz, 1975 has been questioned in the literature, with the latter having been recognised as a distinct lineage, but also synonymised as a colour variant of H. mitchelli . The recent description of a new closely related congener from Mozambique, Hyperolius stictus (Conradie et al., 2018), along with evidence of genetic differentiation within H. mitchelli has suggested that this widely distributed species might be a species complex. In this study, we reassess the relationships of these closely related species with new field sampling, molecular, morphological and bioacoustics analyses with the aim to assign the correct taxonomic identity to H . cf. mitchelli from northern Tanzania. Our results demonstrate that there are four distinct lineages within this group: H. stictus from Mozambique; H. rubrovermiculatus from southern Kenya; H. mitchelli sensu stricto from central and southern Tanzania and Malawi and H . cf. mitchelli from north-eastern Tanzania. Based on our combined analyses we assign H . cf. mitchelli as a new population of H. rubrovermiculatus with distinct colouration, extending the range of this species from Kenya into northern Tanzania. We also clarify the genetic, morphological and acoustic variation within and between all lineages to further knowledge of this group and provide direction for future study into this fragmented and variable lineage
