Spatial metrics effect of forest fragmentation on forest bird abundance and site occupancy probability: the influence of patch size and isolation
Item type: Journal Article • Journal: Ostrich: Journal of African Ornithology • Authors: Robert B Modest --- Department of Wildlife Management, Tanzania Shombe N Hassan --- Department of Wildlife Management, Tanzania Alfan A Rija --- Department of Wildlife Management, TanzaniaThe persistence of species taxa within fragmented habitats is dependent on the source–sink metapopulation processes, and forest patch size and isolation are key factors. Unveiling species–patch area and/or species–patch isolation relationships may help provide crucial information for species and landscape... -
Effect of short-duration overnight cattle kraaling on grass production in a southern African savanna
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: Pamela Sibanda --- National University of Science and Technology, Zimbabwe Allan Sebata --- National University of Science and Technology, Zimbabwe Edward Mufandaedza --- Africa Centre for Holistic Management, Zimbabwe Mukai Mawanza --- National University of Science and Technology, ZimbabweRanch owners in eastern and southern Africa have embraced a new rangeland management practice of keeping cattle overnight in temporary livestock corrals (hereafter referred to as kraals) within rangelands for short durations (for example, one week) to improve grass production... -
First genetic data for band-winged grasshoppers (Orthoptera: Acrididae: Oedipodinae) of the Biskra region of Algeria with new records for the country
Item type: Journal Article • Journal: African Zoology • Authors: Abdelhamid Moussi --- Laboratory Valorization and Conservation of Natural Resources, Algeria Lara-Sophie Dey --- General Zoology, Germany Daniel Petit --- UMR 1061 Inra, France Abderrahmane Abba --- Laboratory Valorization and Conservation of Natural Resources, Algeria Robert Klesser --- General Zoology, Germany Martin Husemann --- Centrum für Naturkunde, GermanyDNA barcoding represents an objective tool for fast species identification, especially for taxa for which morphological identification is difficult. One current limitation of barcoding is the lack of reference sequences for many groups. While many European and North American countries... -
Minimum population size and potential impact of feral and semi-feral donkeys and horses in an arid rangeland
Item type: Journal Article • Journal: African Zoology • Authors: Halcyone Muller --- Conservation South Africa, South Africa Amanda Bourne --- Department of Biological Sciences, South AfricaFarmers in the northern, communally managed parts of the Succulent Karoo, an arid rangeland system in South Africa, historically used donkeys and horses for transport and ploughing. With increasing mechanisation, draught animal power has largely been replaced by machines. Yet,... -
First record of Labeo capensis (Smith, 1841) in the Crocodile River (West) system: another successful non-native freshwater fish introduction in South Africa
Item type: Journal Article • Journal: African Journal of Aquatic Science • Authors: JH Erasmus --- Water Research Group, Unit for Environmental Sciences and Management, South Africa W Malherbe --- Water Research Group, Unit for Environmental Sciences and Management, South Africa R Gerber --- Water Research Group, Unit for Environmental Sciences and Management, South Africa OLF Weyl --- DST/NRF Research Chair in Inland Fisheries and Freshwater Ecology, South Africa B Sures --- Aquatic Ecology and Centre for Water and Environmental Research, Germany V Wepener --- Water Research Group, Unit for Environmental Sciences and Management, South Africa NJ Smit --- Water Research Group, Unit for Environmental Sciences and Management, South AfricaSouth Africa is one of six global fish invasion hotspots and as a result, non-native fishes are common components of the fish assemblages in all of the major river systems. The rate of establishment for introduced fish into South African... -
A new puddle frog (Phrynobatrachidae: Phrynobatrachus) from the Mambilla Plateau in eastern Nigeria
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: DavidC. Blackburn --- University of Kansas, USAA new species of puddle frog (Phrynobatrachus) is described from the Kurmin Danko Forest Reserve on the western edge of the Mambilla Plateau in eastern Nigeria. The new species is distinguished from both geographically proximate and closely related Phrynobatrachus species... -
Kraals or bomas increase soil carbon and fertility across several biomes
Item type: Journal Article • Journal: African Journal of Range & Forage Science • Authors: Mia Momberg --- University of Pretoria, South Africa Anna Jean Haw --- , Kenya Perushan Rajah --- , South Africa Jacques van Rooyen --- , Kenya Heidi-Jayne Hawkins --- , South AfricaKnowledge about how pastoralism and kraaling may contribute to desired global objectives, such as soil fertility, is in danger of being lost. We tested whether short duration kraaling increases soil fertility across various biomes and countries via a meta-analysis (random... -
New distribution records and population density of the Critically Endangered Tarzan Chameleon (Calumma tarzan), eastern Madagascar
Item type: Journal Article • Journal: African Journal of Herpetology • Authors: Alain JV Rakotondrina --- Madagasikara Voakajy, Madagascar Raphali R Andriantsimanarilafy --- Madagasikara Voakajy, Madagascar Hanta J Razafimanahaka --- Madagasikara Voakajy, Madagascar Achille P Raselimanana --- , Madagascar Rikki Gumbs --- Zoological Society of London, United Kingdom Caleb Ofori-Boateng --- Zoological Society of London, United Kingdom Jody M Taft --- South African National Biodiversity Institute, Kirstenbosch Research Centre, South Africa Fanomezana M Ratsoavina --- Université d’Antananarivo, MadagascarThe distribution and population density of the Critically Endangered Tarzan Chameleon (Calumma tarzan) in eastern humid forests of Madagascar was studied using line transect-distance sampling. Based on the results from species distribution models, eight sites were visited over a four-month...
