Only 18 specimens from 12 localities have been collected with a few additional observations recorded. Virtually nothing of the species’ natural history is known. We report or summarise new localities and range extensions of P. affinis in Namibia and Zambia and describe the call for the first time. We also compare its call to that of the sister species, P. bifasciatus, describing this call for the first time and noting a considerable range extension. The calls show several key differences, with P. affinis calls generally having a lower dominant frequency, pulse repetition rate, and number of pulses than P. bifasciatus. The calls of Namibian and Zambian P. affinis also show marked differences. These descriptions add valuable natural history information for both species and will considerably improve the field detection of the enigmatic P. affinis.KEYWORDS: advertisement callbioacousticsPhrynomantis affinisrange extensionrare species AcknowledgementsThis work was conducted under the Namibian Commission on Research, Science and Technology permit number AN20191118.

{"title":"Testing the thermal melanism hypothesis for Cape Cobras ( <i>Naja nivea</i> ) using community science photographic data","authors":"Jody M Barends, Kim J Scholtz","doi":"10.1080/21564574.2023.2263464","DOIUrl":"https://doi.org/10.1080/21564574.2023.2263464","url":null,"abstract":"ABSTRACTAnimal colour is a highly adaptive phenotypic trait that can respond to several selection pressures, including those facilitated by variations in climate. The thermal melanism hypothesis predicts that for ectotherms, selection for darker phenotypes should be highest in cooler areas because darker pigmentation should provide thermoregulatory advantages. We tested whether intraspecific variation in colour distribution of Cape Cobras (Naja nivea) conforms to this hypothesis using a dataset of ∼800 georeferenced photographs of cobras available from community science platforms. We scored the dorsal colouration of snakes in each photograph and tested for associations between snake colours and climate variables at those locations. Our results provide strong evidence to suggest that temperature and solar radiation are important predictors of N. nivea colour occurrence, whereas elevation and precipitation are not. Overall, darker snakes have a significantly higher probability of occurrence in colder areas with low solar radiation than lighter snakes, which are more likely to occur in hotter areas with more solar radiation. Our study is the first to provide evidence for thermal melanism in a sub-Saharan African snake species, which was made possible by the availability of community science data.KEYWORDS: Cape Cobraclimatecolour variationsnakesthermal melanism AcknowledgementsWe thank Darren Pietersen and Rene Navarro for facilitating availability of reptileMAP data.

{"title":"Frog and reptile conservation through the lens of South Africa’s nature-based cultural practices","authors":"Fortunate M Phaka, Jean Hugé, Maarten PM Vanhove, Louis H du Preez","doi":"10.1080/21564574.2023.2261021","DOIUrl":"https://doi.org/10.1080/21564574.2023.2261021","url":null,"abstract":"ABSTRACT Ethnoherpetology improves our understanding of the conservation implications of nature-based cultural practices through investigations of the influence of traditional culture on frog and reptile species (herptiles). Improved understanding of the implications of human activities on these taxa is especially important as herptiles are experiencing global population declines. Furthermore, improved understanding of nature-based cultural practices can better inform conservation planning that includes cultural practices as defined by South African legislation. The herptile-based cultural practices recorded from a sample of 275 online questionnaire respondents and 68 publications show some cultural practices to compel or inspire protection of herptiles. Conversely, other practices were found to pose a conservation risk as they either involve killing herptile species or they perpetuate negative perceptions towards them. Leveraging protective cultural practices as a conservation tool and mitigating culture-motivated threats requires integrating cultural aspects into modern law. Such an integrative approach is possible under South African legislation’s provisions for socially inclusive conservation planning and recognition of customary law. Integrative conservation approaches are also in line with international policy such as the Kunming-Montreal global biodiversity framework. In addition to an inventory of herptile-based cultural practices, the study also assesses their feasibility as conservation tools. Furthermore, this study highlights a need for quantification of their conservation implications (both positive and negative) and aligning protective traditional cultural practices with modern means of law enforcement.","PeriodicalId":55550,"journal":{"name":"African Journal of Herpetology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135512385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twelve sites, each encompassing a combination of vegetation type, elevation, slope and aspect, were sampled for S. inornatus using dug quadrats, pitfall-and funnel-trap arrays, and coverboard arrays. Seven S. inornatus were recorded, at least one by each sampling method. Individuals were captured at the forest edge and in the grassland part of the forest-grassland ecotone and none were captured in the interior of the forest. None of the sampling methods were suitable for the long-term monitoring of S. inornatus, although a modification of the coverboard array using terracotta tiles instead of corru-board tiles should be tested. Five S. inornatus captured were introduced to the Johannesburg Zoo’s ex-situ insurance and captive-breeding population. Nine other sympatric species of herpetofauna were recorded during the survey, with the Bush Squeaker Arthroleptis wahlbergii Smith, 1849 the most caught and S. inornatus ranking fifth. This study provides information that is useful for addressing some of the conservation actions and research needed for S. inornatus, but more research on the biology of this skink (particularly on its life history and population size) and habitat management interventions (restoration and rehabilitation of its habitat) are required to assist with improving its conservation status.","PeriodicalId":55550,"journal":{"name":"African Journal of Herpetology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135617303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We utilised an integrative taxonomic approach with morphological and genetic data to reconcile the taxonomic status of these cryptic lineages, including the recently described taxon P. brunneus from West Africa. We sequenced three mitochondrial (16S, cyt b and ND4) and two nuclear (c-mos and RAG1) genes from several Central African populations of P. carinatus and combined our data with other closely related species to infer a maximum likelihood phylogenetic tree with IQ-TREE. Our results are consistent with previous studies that showed P. cf. carinatus populations from Democratic Republic of the Congo (DRC) represent a cryptic lineage that is distinct from P. carinatus sensu stricto in Cameroon, Central African Republic, Equatorial Guinea (including Bioko Island), Gabon, eastern Nigeria, Republic of the Congo, and extreme western DRC. In our preferred tree, P. brunneus (limited to 16S molecular data) was recovered as a relatively long branch in a moderately supported clade with P. carinatus sensu stricto, whereas P. cf. carinatus populations from northern Angola, most of DRC, and East Africa (Burundi, Kenya, Rwanda, Tanzania and Uganda) were described as a new species. A possible hybrid population between south-eastern Cameroon and north-western DRC is consistent with an increasing body of evidence suggesting the Ubangi River might represent a hybrid zone area.KEYWORDS: Congo RiverUbangi RiverCongo Basinendemism ACKNOWLEDGEMENTSWe thank Jonathan Brecko and Garin Cael for facilitating access to RMCA specimens; Bo Delling and Andrea Hennyey for NRM type specimens; Mark-O.
