We quantified habitat associations and evaluated the conservation status of a recently identified, undescribed species of dwarf chameleon, Bradypodion sp. nov. Dhlinza, endemic to scarp forest remnants in KwaZulu-Natal Province, South Africa. At the microhabitat scale the Dhlinza dwarf chameleon was found more often in forest gaps and near paths than highly disturbed edges or forest interior. Chameleon presence was not explained by forest physiognomic variables such as vine cover, shrub and tree density, or canopy cover. Presence near gaps may be better explained by the combined effects of the thermal microenvironment and food availability. The species is moderately common where it occurs, with estimated densities of 4.7, 8.7 and 29.7 individuals per ha within forest interior, edges and gaps respectively. At the landscape scale, the chameleon occurs only in three remnant forests: the Dhlinza, Entumeni and Ongoye Forests. The species' extent of occurrence was estimated to be 88 km2 and its area of occupancy 49 km2. Based on the small area of remaining suitable habitat, this species meets the requirements for categorization as Endangered according to IUCN Red List criteria.

Abstract A description is provided for Asperisporium vitiphyllum, a colonizer of living leaves, causing a leaf spot or brown leaf blotch and leaf drying. Some information on its habitat, dispersal and transmission, and conservation status is given, along with details of its geographical distribution (Africa (Morocco and South Africa), Asia (Armenia, China, Georgia, Iran, Iraq, Israel, Kazakhstan (Almaty oblast), Kyrgyzstan, Pakistan, Tajikistan, Turkmenistan and Uzbekistan), Europe (Moldova, Russia (Krasnodar krai, Leningradskaya oblast, Stavropol krai) and Ukraine)) and hosts (including Vitis vinifera).

Abstract A description is provided for Barrmaelia oxyacanthae, saprobic on wood of various trees. Some information on its dispersal and transmission and conservation status is given, along with details of its geographical distribution (Africa (South Africa), North America (Canada, USA (New Jersey, North Dakota, South Dakota, Vermont, Virginia)), Asia (Georgia, Japan, Kazakhstan (Aktyubinskaya oblast), Pakistan), Europe (Belarus, Belgium, former Czechoslovakia, Finland, France, Germany, Italy, Lithuania, Luxembourg, Netherlands, Norway, Poland, Sweden, Switzerland, Ukraine, UK, former Yugoslavia)). B. oxyacanthae is sometimes found on elm twigs previously gnawed by rabbits.

Microbial Community Dynamics

In the commercial BIOX® process, an acidophilic mixed bacterial and archaeal community dominated by iron and sulphur oxidising microorganisms is used to facilitate the recovery of precious metals from refractory gold-bearing sulphidic mineral concentrates. Characterisation of the microbial communities associated with commercial BIOX® reactors from four continents revealed a significant shift in the microbial community structure compared to that of the seed culture, maintained at SGS (South Africa). This has motivated more detailed study of the microbial community dynamics in the process. Microbial speciation of a subset of the BIOX® reactors at Fairview mines (Barberton, South Africa) and two laboratory maintained reactors housed at Centre for Bioprocess Engineering Research, University of Cape Town, has been performed tri-annually for three years by quantitative real-time polymerase chain reaction. The laboratory BIOX® culture maintained on Fairview concentrate was dominated by the desired iron oxidiser, Leptospirillum ferriphilum, and sulphur oxidiser, Acidithiobacillus caldus, when operated under standard BIOX® conditions. Shifts in the microbial community as a result of altered operating conditions were transient and did not result in a loss of the microbial diversity of the BIOX® culture. The community structure of the Fairview mines BIOX® reactor tanks showed archaeal dominance of these communities by organisms such as the iron oxidiser Ferroplasma acidiphilum and a Thermoplasma sp. for the period monitored. Shifts in the microbial community were observed across the monitoring period and mapped to changes in performance of the commercial process plant. Understanding the effect of changes in the plant operating conditions on the BIOX® community structure may assist in providing conditions that support the desired microbial consortium for optimal biooxidation to maximize gold recovery.
