We assessed the impact of anthropogenic disturbances on lepidopteran assemblages across five different land use types (Fragmented Forest, Crop Fields, Pasture Land, Rural Settlements and undisturbed Natural Forest) in the Choke Mountains, Ethiopia. Lepidoptera were sampled using 20 W UV LED lights in 19 sites for 12 consecutive months. A total of 4 559 specimens representing 14 families and 339 species were sampled. The highest diversity was obtained from the Natural Forest, followed by the Fragmented Forest, Rural Settlements, Pasture Land and Crop Fields. The monthly trends of the diversity estimates showed strong differences among the five land use types, with months when the highest Hill–Shannon and Hill– Simpson values were observed not in the Natural Forest, but in the Rural Settlements and Fragmented Forest. The highest dominance values were observed in the Crop Fields and Pasture Land, with dominant species percentages of about 10%. The multivariate results clearly highlight the separation of the Natural Forest sites from all other sites and, in general, great consistency within each land use. A high positive linear relationship between the number of vascular plants and sampled Lepidoptera species was observed. The results of this study will be useful for guiding conservation management priorities to prevent irreversible biodiversity loss and maintain ecosystem provisioning services that are essential for the sustainable development of rural communities.Keywords: mothsAfricaland useecosystem monitoringdiversity measures","PeriodicalId":55548,"journal":{"name":"African Zoology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135820966","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}

Of these, the diets of four species have been studied in sufficient detail to facilitate interspecific comparisons. The diets of the aardvark Orycteropus afer, aardwolf Proteles cristatus, bat-eared fox Otocyon megalotis and Temminck's pangolin Smutsia temminckii were compared based on the overall prey categories utilised and the proportion of each prey category in their diets, while Meller's mongoose Rhynchogale melleri had too few data to be assessed. Bat-eared fox fed on the greatest number of prey categories (n = 116) and had the greatest dietary niche breadth (4.71), while aardwolf utilised the fewest prey categories (n = 28) and had the lowest dietary niche breadth (1.19) when analysing the proportion of each prey category in the diet at the genus level. Temminck's pangolin was the only species that was observed to feed exclusively on ants and termites. The diets of Temminck's pangolin and aardvark showed a moderate degree of overlap (dietary niche breadth 0.49–0.57), but overlap was low between all other species pairs (0.01–0.26) when analysing the proportion of each prey item in the diet at the genus level. The results suggest that these myrmecophages have low to moderate dietary overlap, which combined with the high abundance of ants and termites and differences in their feeding ecologies, likely reduces interspecific competition.","PeriodicalId":55548,"journal":{"name":"African Zoology","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"59918655","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}

To protect these organisms and to gather basic knowledge, an anuran biodiversity study was conducted in the lower Ouémé Valley in Benin. Anurans were inventoried in five types of habitats in four municipalities. Visual and auditory detections were used to observe, count and/or catch specimens at night, aided by headlamps. Five physico-chemical parameters were simultaneously measured. Species were determined using identification keys, authenticated by specialists at the Leibniz Institute for Evolution and Biodiversity Science's Museum für Naturkunde, Berlin. Our study observed 28 species, with several species living in degraded forests. Afrixalus fulvovittatus (Cope 1860) was recorded for the first time in Benin; and the taxonomic status of three anuran species, Sclerophrys sp., Hyperolius sp. and Arthroleptis sp., still require clarification. Among the species inventoried, Hyperolius torrentis is listed as vulnerable by the IUCN category. Anuran distribution was closely related to ambient air temperature and soil humidity, with abundance increasing with low ambient air temperature and high soil humidity. We note the importance of protecting these organisms' habitats in order to maintain the optimal environment for their growth and breeding.","PeriodicalId":55548,"journal":{"name":"African Zoology","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42776074","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}

A total of 1 042 fish were tagged over a period of 16 years and 255 individuals (24.5%) were recaptured, some of them on multiple occasions. Data analysis showed that 84.7% of recaptured fish remained in relatively small home ranges (∼750 m linear distance), while 13.3% abandoned their home ranges and undertook unidirectional movements (of 21–1 211 km) along the KwaZulu-Natal coast in a north-easterly direction, most likely to spawn. While the no-take area of the PMPA provides effective protection for resident fish, the export of adult P. praeorbitalis provides strong evidence of the benefits that no-take MPAs can offer to adjacent fisheries. Based on the tag-recapture length data, the growth rate was found to be relatively slow, averaging 46 mm y–1. This growth rate was similar to that determined by a study of ageing using sectioned otoliths. Reliable tag-recapture data can thus be used to provide a valuable means of validating growth rates determined by other methods.","PeriodicalId":55548,"journal":{"name":"African Zoology","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47571690","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}

Because of their ecological importance, these areas are regularly considered for agricultural purposes. Scorpion assemblages often exhibit higher levels of species diversity in dry habitats and are beneficial indicators in ecological studies in such environments. In this study, we investigated the effects of climatic and spatial predictors on beta diversity patterns among scorpion assemblages distributed in the drylands of Egypt. Scorpion occurrences were compiled from the scientific literature. For each location, we created a set of climatic variables related to precipitation, temperature, and solar irradiation, as well as spatial predictors. A total of 134 scorpion occurrences were obtained, comprising 21 species grouped into three families. Climatic and spatial variables together influenced the patterns of scorpion diversity in Egyptian landscapes. Species replacement accounted for 69% of the total beta diversity. In addition, species replacement was positively affected by climatic and spatial variables. Our results suggest a reciprocal link between the region's ecological history and the patterns of beta diversity observed in scorpion assemblages from Egyptian drylands.","PeriodicalId":55548,"journal":{"name":"African Zoology","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47470806","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}

It is the most-farmed freshwater fish species in EAC and the second-most-farmed worldwide. Currently, in EAC, through direct stocking activities and likely indirectly via aquaculture escapees, Nile tilapia are present in waterbodies where it is not native and where it is thought to have contributed to the fish biodiversity loss observed in recent decades. Introduced Nile tilapia may hybridise with native, congeneric species, promoting genetic introgression that can be detrimental to the sustainability of biodiversity. Moreover, the translocation dynamics and escapes from aquaculture can contribute to artificial geneflow between Nile tilapia stocks, compromising their gene pool and the sustainability of the species as a fishery resource. In the current work, we review some examples of these phenomena in EAC. Additionally, we explore the importance of collecting genetic data to define baseline knowledge for native and non-native Nile tilapia populations that can be used in monitoring programmes for development, management and conservation of tilapia genetic resources.","PeriodicalId":55548,"journal":{"name":"African Zoology","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45843767","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}

A total of 80 H. vittatus individuals consisting of 56 females and 24 males were examined for endohelminth parasites during the period October 2014–July 2015 in the Sanyati basin, Lake Kariba. Parasites were recovered from the abdominal cavity, mesentery and intestines. Most of the parasites were harboured in the abdominal cavity in both sexes. Parasite infection was more prevalent during the dry season in comparison to the rainy season for both sexes. Contracaecum larval infection was significantly higher in female (84%) than in male tigerfish (24%), whereas larval cestode infections were significantly higher in male tigerfish (59%) than female fish (16%). The mean condition factor of the male tigerfish (1.68) was not significantly higher than that of the female (1.64). The results of the study indicate that female tigerfish were more suitable hosts to Contracaecum larval infection than the male fish. Further parasitological and histopathological research on tigerfish is recommended to contribute to knowledge on endohelminth diversity and conservation.","PeriodicalId":55548,"journal":{"name":"African Zoology","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45900909","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}

In this study, a multi-method comparative approach was used to survey bat species in the foothills of the Drakensberg Mountain range in KwaZulu-Natal province, South Africa. We used historical museum records and species distribution modelling (SDM) to predict which species would likely occur in our study area. We then compared physical capture (by deploying mist nets) with acoustic surveys (using an Anabat bat detector) to assess the bat species assemblages present. Species distribution models predicted eight bat species to occur from the historical checklist of 28 species recorded in the broader region, as no museum records existed for the specific study area. Species detection by acoustic data yielded the highest number of detected species (n = 11) while active trapping yielded nine species from 54 individuals of four families, namely, Laephotis botswanae, L. capensis, Myotis tricolor, Pipistrellus hesperidus, Rhinolophus clivosus, and Tadarida aegyptiaca with molecular confirmation required for Miniopterus fraterculus, R. darlingi and R. swinnyi. These complementary sampling methods may be necessary for accommodating the limitations of each individual method for a more inclusive assessment of bat species richness in a targeted landscape.
