Flight Initiation

With tourism in South Africa expanding, the number of avitourists increases. The increase in infrastructure and human activities in protected areas, if not managed properly, can be harmful to birds. Flight initiation distances (FID) can be used as a method to monitor habituation to disturbances. This study was performed at the Barberspan Bird Sanctuary, North West province, South Africa, to determine the levels of habituation among waterbirds and make appropriate recommendations regarding the management of the reserve. Our results indicated a 0.29 m increase in FID per gram reported mean biomass. Compared with conspecific or congeneric birds from Australia, Europe and North America, South African birds have relatively larger FIDs to human disturbance, which may indicate lower habituation. We also calculated buffer zones based on the maximum FID of the waterbirds for three mass groups. These buffer zones were then matched with the spatial distribution of the birds along the shoreline. We recommend that the mean FID for the blacksmith lapwing, Vanellus armatus (62 m), can be used as approach distance outside the breeding season in areas where the birds are sparsely distributed and 104 m during the breeding season in breeding areas. A large buffer of 200 m is suggested for areas with threatened, sensitive and skittish species. However, it is still preferable for avitourists to use the bird hides along the shores.Conservation implications: This study provides information for conservation management at Barberspan, based on typical birder activity. Smaller birds would need smaller buffer zones, while larger birds need much greater distances from observers to minimise disturbance. Similar studies can be applied elsewhere.

Setswana (also known as ‘Tswana’ or, more archaically, ‘Chuana’ or ‘Sechuana’) is a Bantu language (group S.30; ISO code tsn) spoken by an estimated four million people in South Africa. There are a further one million or more speakers in Botswana, where it is the dominant national language, and a smaller number of speakers in Namibia. The recordings accompanying this article were mostly produced with a 21-year-old male speaker from the area of Taung, North-West province, South Africa. Some of the accompanying recordings are of a 23-year-old female speaker from Kuruman (approximately 150 km west of Taung). The observations reported here are based on consulting with both these speakers, as well as a third speaker, from Kimberley. All three were speakers of South African Setswana varieties. For discussion of some differences between these varieties and more Northern and Eastern Setswana dialects – including those spoken in Botswana – see (Doke 1954, Cole 1955, University of Botswana 2001).

Functional multilingualism in South Africa: an unattainable ideal? Although much has been done on an official level to establish true multilingualism in South Africa, a tendency towards English monolingualism seems to exist in the country. The aim of this article is to describe the official stipulations in pursuit of multilingualism, as they appear in the Constitution (Act 108 of 1996), the School Act (Act 84 of 1996) and the final report of Langtag. In addition to the present demands, the article also responds to previous demands for multilingualism in the South African context, particularly as stated in the Bantu Education Act of 1953. It is argued that, because of the negative connotations associated with mother-tongue instruction in the past, contemporary mother-tongue instruction will also be contaminated. Apart from the theoretical investigation into multilingualism, the article reports on empirical research that has been done in this regard in the North West Province where the attitudes and perceptions of the school population towards the regional languages were measured. Although the subjects reacted positively to the official status granted to several South African languages, they expressed a preference for English as working language because of the access it gives to personal, economic and social development and empowerment. The article concludes with brief recommendations regarding language planning opportunities that derive from this situation.

Onderstepoort Journal of Veterinary Research, T5:95-102 Sera from 19 wild caught vultures in northern Namibia and 15 (12 wild caught and three captive bred but with minimal histories) in North West Province, South Africa, were examined by an enzyme-linked immunosorbenats say( ELISA)f or antibodiesto the Bacillus anthracis toxin protective antigen (PA). As assessed from the baseline established with a control group of ten captive reared vultures with well-documented histories, elevated titres were found in 12 of the 19 (63%) wild caught Namibian birds as compared with none of the 15 South African ones. There was a highly significant difference between the Namibian group as a hole and the other groups (P < 0.001) and no significant difference between the South African and control groups (P > 0.05). Numbers in the Namibian group were too small to determine any significances in species-, sex- or age-related differences within the raw data showing elevated titres in four out of six Cape Vultures, Gyps coprotheress, six out of ten Whitebacked Vultures, Gyps africanus, and one out of three Lappet-faced Vultures, Aegypiust racheliotus, or in five of six males versus three of seven females, and ten of 15 adults versus one of four juveniles. The results are in line with the available data on the incidence of anthrax in northern Namibia and South Africa and the likely contact of the vultures tested with anthrax carcasses. lt is not known whether elevated titre indicates infection per se in vultures or absorption of incompletely digested epitopes of the toxin or both. The results are discussed in relation to distances travelled by vultures as determined by new tracking techniques, how serology can reveal anthrax activity in an area and the issue of the role of vultures in transmission of anthrax.

Aims: Maize is of great significance in the national food security of South Africa. Maize production levels in South Africa continue to decline, further deteriorating the situation of increased food insecurity, unemployment and increased poverty levels in the face of increasing population. This paper investigated fundamental variables influencing maize yield in the South African major maize producing regions. Study Design: A multi-stage stratified sampling method was employed to select maize producing farmers in the major maize producing provinces, namely Mpumalanga, Free State and North West provinces of South Africa. Furthermore, three districts were selected from which maize farmers were then selected. Methodology: Using linear multiple regression for a sample of 202 maize farmers, maize yield as a dependent variable was regressed against land size, fertilizer usage, labour, herbicides and seeds as independent variables. The paper employed the Cobb-Douglas production function to estimate parameters. The data obtained from the field were subjected to analysis using inferential statistics using SPSS v20. Results: The study showed that fertilizer, labour, and herbicides used in the production of maize in the study area were positively and statistically significant at a 5% confidence interval (P<0.05) with elasticity coefficients of 0.55, 0.47 and 0.198 respectively. The independent variables computed in the model had positive elasticity coefficients indicating a direct positive relationship between the input variables and maize output. The study also revealed that farmers in the study area were applying fewer amounts of fertilizer than the recommended rates per hectare. Conclusion: The study recommends that the South African government should supply inputs to maize farmers at subsidized rates to promote correct application rates and attain higher yields.  The promotion of good quality extension services to foster good agricultural practices in the production of maize is also recommended.

The article reviews the outbreaks and distribution of African swine fever (ASF) in South Africa since the first probable outbreak that occurred in the Koedoesrand Ward in 1926. Retrospective data on the ASF outbreaks in South Africa were obtained from the World Organisation for Animal Health (OIE) disease database and the South African veterinary services annual reports in addition to published articles and online sources. South Africa has experienced many outbreaks that can be divided into 2 time periods: the period before the development of the OIE diseases database (1993) and the period after. More than 141 outbreaks of ASF were reported during the first period. Since the development of OIE disease database, 72 outbreaks directly involving 2968 cases, 2187 dead and 2358 killed pigs mainly in smallholder pig farms were reported. The median number of cases for a given ASF outbreak is 17, but in 50% of outbreaks no pigs were killed for prevention. The most important ASF outbreak was reported in April 2014 in the Greater Zeerust district (North West province) involving 326 cases and 1462 killed pigs. However, the outbreak with highest mortality involving 250 pigs was reported in 2016 (Free State province). According to phylogenetic analysis, nine p72 genotypes (I, III, IV, VII, VIII, XIX, XX, XXI and XXII) have been identified in South Africa. Season-wise, more outbreaks were recorded during summer. It was also observed that the OIE disease database could contain errors that would have been introduced through compiled forms at country level. Spatiotemporal studies on ASF outbreaks in South Africa are therefore required in order to assess statistically and quantitatively the clustering of outbreaks over space and time.

Diversity and seasonal occurrence of coccidia in a communally reared mixed flock of sheep and goats at Mafikeng, North West Province, South Africa, was determined between March 2008 and February 2009. Faecal specimens were collected directly from the rectum of the animals and the number of oocysts per gram of faeces (opg) determined. The mean monthly opg for goats was significantly higher than that for sheep. Higher oocyst counts were observed during the hot, rainy season than during the cold, dry season. The highest mean values for both the sheep (862.5 opg) and goats (1200 opg) were recorded during March. Six species (Eimeria crandallis, E. bakuensis, E. weybridgensis, E. ahsata, E. intricata, and E. ovinoidalis) were recovered from sheep, with E. crandallis and E. bakuensis occurring most frequently. The last 2 species, together with E. ahsata, are considered among the most pathogenic species in sheep. In goats, 7 species (E. arloingi, E. jolchijevi, E. caprina, E. alijevi, E. caprovina, E. christenseni and E. hirci) were recovered, with E. arloingi and E. jolchijevi occurring most frequently. Up to 5 Eimeria species were recovered from individual specimens in goats while up to 4 were recovered in sheep. No cross-infections between goats and sheep were recorded and no clinical coccidiosis was noted during the study. It is increasingly becoming evident that the pathogenic E. arloingi is one of the most commonly occurring Eimeria species in goats in South Africa.

The Cost

The wide adoption of EIA internationally is implicitly or explicitly based on the assumption that the benefits of EIA outweigh the costs. However, there has been surprisingly little empirical research conducted on the "cost" of EIA. The latter has been mostly because of the difficult methodological challenges it presents, which include the difficulties associated with clarifying terminology and disentangling what is meant by "cost". South Africa has been a leading developing country in terms of the introduction of EIA. However, almost a decade of mandatory EIA practice has raised serious questions about unjustified and unnecessary time delays and monetary costs and a desperate need for improved efficiency and effectiveness. In light of the latter the urgent need to gain a better understanding of the "cost" of EIA is evident. This paper presents preliminary results of an empirical study on the "direct EIA cost" in relation to "overall project cost" in South Africa. The data was obtained from a detailed survey of 148 EIAs conducted in the Free State, North West and the Northern Cape Provinces. The research suggests that the average direct cost of EIA within this region of South Africa is particularly low compared to international EIA systems. However, as a percentage of total project cost, EIA in South Africa compares with the higher spectrum of international practice. The latter suggests that within the South African context a large number of EIAs are being conducted for relatively small scale projects and that the main cost burden is placed on small and medium economic enterprise. In conclusion the overall profile of EIA cost in the South African context is described in relation to four broad project categories. To take the debate forward and to allow for regional comparative analysis, it is proposed that the research be expanded to include other provinces.

Background: Leopards (Panthera pardus) show genetically determined colour variation. Erythristic (strawberry) morphs, where individuals are paler and black pigment in the coat is replaced by a red-brown colour, are exceptionally rare in the wild. Historically, few records exist, with only five putative records known from India.Objectives: To record the presence of erythristic leopards in our study site (Thaba Tholo Wilderness Reserve, Mpumalanga) and to collate records from across South Africa. Method: A network of camera traps was used to record individual leopards at Thaba Tholo. We also surveyed local experts, searched the popular South African press, and used social media to request observations.Results: Two out of 28 individual leopards (7.1%) recorded in our study site over 3 years were of this colour morph. We obtained records of five other erythristic leopards in the North West and Mpumalanga regions, with no reports outside of this population.Conclusions: Erythristic leopards are widely dispersed across north-east South Africa, predominantly in the Lydenburg region, Mpumalanga. The presence of this rare colour morph may reflect the consequences of population fragmentation.
