South African giraffe (Giraffa camelopardalis giraffa) have been introduced as an extralimital species to private farms in the Little Karoo on the basis of economic sustainability, and the need to create a competitive tourism product. However, little is known about the medium- to long-term impacts and ecological sustainability of such introductions. The diet of a population of giraffe on Sanbona Wildlife Reserve, near the town of Ladismith, was assessed via direct observations between January and October 2014, in order to determine their potential impact on the world’s most species-rich semi-desert, the Succulent Karoo. Unlike giraffe in their native range, the Sanbona population showed seasonal preference for browse species. Acacia karroo (sweet thorn) appears to be the preferred browse species during autumn and spring, with Schotia afra being the preferred species in winter, and no significant preference being shown in summer. Giraffe also appeared to seasonally move between catchments where tree species other than A. karroo occurs, especially during winter and spring when the tributaries of the Brak River, containing mixed Acacia with S. afra (karoo boer-bean) and Euclea undulata (small-leaved guarri), were visited with increasing frequency. These results largely confirm the importance of A. karroo as the main browse species in this environment but also suggest that other species may be important components of the diet of extralimital giraffe in the Little Karoo. On farms where A. karroo is dominant, supplementary feed may be needed when A. karroo browse is unavailable due to leaf drop.Conservation implications: Acacia karroo was the main browse species of extralimital G. c. giraffa at Sanbona Wildlife Reserve, but it switched to S. afra during winter. This suggests that an assessment of alternative food species forms part of suitability assessments for the introduction of extralimital G. c. giraffa for areas similar to Sanbona.

Abstract A description is provided for Cylindrocladiella elegans. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: Arachis hypogaea, Eucalyptus leaf litter. DISEASE: Found on peanut roots, leaf litter and in soil. South African isolates have been found to be pathogenic to Medicago truncatula (alfalfa), Arachis hypogaea (peanut), Glycine max (soyabean) and Pisum sativum (pea). GEOGRAPHICAL DISTRIBUTION: South Africa. TRANSMISSION: Probably occurs by wind and splash dispersal.

Abstract A description is provided for Lecanicillium aphanocladii. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. DISEASE: Mainly fungicolous: cobweb and spotting in cultivated Agaricus (NAIR et al., 1980; CHEN et al., 1984; BHARDWAJ et al., 1991; GROGAN, 2000), parasitizing uredospores and inducing teliospore formation in rust fungi (BIALI et al., 1972; FORRER, 1977; KOÇ & DÉFAGO, 1983; SRIVASTAVA et al., 1985b; VOLKER & BOYLE, 1994) and parasitizing powdery mildew (Sphaerotheca fuliginea, HEIJWEGEN, 1988), but also entomogenous (see below). HOSTS: FUNGI: Agaricus bisporus and A. bitorquis, Sphaerotheca fuliginea and S. pannosa (VERHAAR et al., 1999), Puccinia spp. (VOLKER & BOYLE, 1994). INSECTA: Mosquito larvae (LÓPEZ-LASTRA et al., 1992, 2002); Bombyx mori (PATIL et al., 1994), Trialeurodes vaporariorum (ENCHEVA, 1979). Also reported from leaf litter of Abelmoschus esculentus and Acacia karroo. GEOGRAPHICAL DISTRIBUTION: Cosmopolitan. TRANSMISSION: Soil- and air-borne.

Nudaurelia capensis β virus (NβV) is an RNA virus of the South African Pine Emperor moth, Nudaurelia cytherea capensis (Lepidoptera: Saturniidae). The NβV capsid is a T = 4 icosahedron that contains 60T = 240 subunits of the coat protein (Mr = 61,000). A three-dimensional reconstruction of the NβV capsid was previously computed from visions embedded in negative stain suspended over holes in a carbon film. We have re-examined the three-dimensional structure of NβV, using cryo-microscopy to examine the native, unstained structure of the virion and to provide a initial phasing model for high-resolution x-ray crystallographic studiesNβV was purified and prepared for cryo-microscopy as described. Micrographs were recorded ∼1 - 2 μm underfocus at a magnification of 49,000X with a total electron dose of about 1800 e-/nm2.

Summary: In the past suicidal behavior among Black South Africans has been largely underresearched. Earlier studies among the other main ethnic groups in the country showed suicidal behavior in those groups to be a serious problem. This article briefly reviews some of the more recent research on suicidal behavior in Black South Africans. The results indicate an apparent increase in suicidal behavior in this group. Several explanations are offered for the change in suicidal behavior in the reported clinical populations. This includes past difficulties for all South Africans to access health care facilities in the Apartheid (legal racial separation) era, and present difficulties of post-Apartheid transformation the South African society is undergoing, as the people struggle to come to terms with the deleterious effects of the former South African racial policies, related socio-cultural, socio-economic, and other pressures.
