An annotated checklist of the mammals recorded by direct or indirect means on or near the Augrabies Falls National Park, is provided. Speculations are offered as to which species have become locally extinct during historical times. The , Orange River as a faunal dispersal corridor and barrier, is considered. A numerical analysis to determine whether the Augra- bies Falls district falls within the Namib or the South West Arid biotic zone, is discussed.

This study compares, for the first time, variation in estimates of susceptibility of native flora to Phytophthora cinnamomi Rands among four databases and proposes an estimate of the proportion of the flora of the South-West Botanical Province of Western Australia that is susceptible to the pathogen. Estimates of the susceptibility of south-western native flora to P. cinnamomi infection were obtained from databases for Banksia woodland of the Swan Coastal Plain, jarrah (Eucalyptus marginata Donn. ex Smith) forest, the Stirling Range National Park and Rare and Threatened Flora of Western Australia. For the woodland, forest and national park databases, hosts were naturally infected in uncontrolled diverse natural environments. In contrast, threatened flora were artificially inoculated in a shadehouse environment. Considerable variation occurred within taxonomic units, making occurrence within family and genus poor predictors of species susceptibility. Identification of intra-specific resistance suggests that P. cinnamomi could be having a strong selection pressure on some threatened flora at infested sites and the populations could shift to more resistant types. Similar estimates of the proportion of species susceptible to P. cinnamomi among the databases from the wide range of environments suggests that a realistic estimate of species susceptibility to P. cinnamomi infection in the south-western region has been obtained. The mean of 40% susceptible and 14% highly susceptible equates to 2284 and 800 species of the 5710 described plant species in the South-West Botanical Province susceptible and highly susceptible to P. cinnamomi, respectively. Such estimates are important for determining the cost of disease to conservation values and for prioritising disease importance and research priorities. P. cinnamomi in south-western Australia is an unparalleled example of an introduced pathogen with a wide host range causing immense irreversible damage to unique, diverse but mainly susceptible plant communities.

Matrices are developed in order to convert published chlorophyll concentrations to values which would have been obtained had correct spectrophotometric equations been used. The main result is to decrease chlorophyll a values by as much as 23 % and chlorophyll a values by as much as 78 %. Corrected average values are given for the South-East Indian and South-West Pacific Oceans. Corrected values are given of the productivity index of several regions in the South-West Pacific Ocean. Some published values for the chlorophyll content of marine algae are corrected.

The Western Australian genus Scholtzia Schauer (1843: 241), is one of the larger genera in the tribe Chamelaucieae of family Myrtaceae with more than 40 species, chiefly found from Carnarvon south to near Harvey and inland to Anderson Rocks, north of Hyden, northern sand plains of the South West Botanical Province and Kalbarri National Park (Rye, 2019). Recently Rye (2019), described twenty-five new species and five new subspecies. One newly described species, Scholtzia denticulata Rye (2019: 55) is illegitimate as it is a later homonym of Scholtzia denticulata F. Mueller (1864: 75).Therefore, a new replacement name is proposed here in accordance with article 53.1 of Shenzhen Code (Turland et al. 2018).

Forest/habitat fragmentation and Human-elephant conflicts are among the key factors that are of great concern to conservationists as far as achieving the goals of elephant conservation within their range states is concerned. Although much has been done in some protected areas in the Central African Sub-Region in general and in Cameroon in particular on forest/habitat fragmentation and human-elephant conflicts, very little is known of this situation in the Takamanda-Mone Landscape of South West Cameroon. The absence of such a valuable baseline data has created a knowledge gap that need to be closed and at the same time provides the management bench of the Landscape with appropriate tools for decision making. In the light of the above, there is therefore the need to source baseline information with respect to forest/habitat fragmentation and human-elephant conflicts in the Takamanda National Park and Mone Forest Reserve. It is from this back drop, that this study ‘on the evaluation of forest/habitat fragmentation and Human-elephant conflicts in the Takamanda-Mone Landscape of the South West Region of Cameroon was initiated as a contribution to the ongoing regional search for baseline information on the forest/habitat fragmentation and human elephant conflicts in Cameroon. The study in order to achieve set objectives employed socio-economic and Biological assessment techniques. Biological assessment took the form of line transect establishment, a hunter guided survey, the use of the Global Positioning Systems (GPS Garmin 60CSx) and the Geographic Information System (GIS). The socio-economic techniques made use of the random and the purposive sampling methodologies for the selection of villages and the respondents for questionnaire administration. Alongside these sampling techniques, some selected Participatory Rural Appraisal (PRA) tools were used for data collection. Results revealed that forest/habitat fragmentation and human-elephant conflicts are very prominent in the Takamanda-Mone Landscape due to human activities that are carried out in the area. These activities were identified to range from farming, hunting, poaching, local timber exploitation, Non-timber Forest Products (NTFPs) gathering, road construction to settlement. The associated conflicts (both direct and indirect) were identified to span from crop destruction to loss of lives and injuries. The locations and the effective carry out of these activities were found to have fragmented forest/ habitats and these has resulted in the decline of elephant populations in the study area. In order to reverse the present trend of events, the Takamanda-Mone landscape should be upgraded and classified into a National Park.

AbstractThe geometric tortoise, Psammobates geometricus(L.), is one of eleven South African species. It is confined to the south-west Cape region. A 7.5 ha reserve of natural veld was established near Paarl in 1972. By 1976, 80P. geometricus and by 1980,170P. geometricus and 94 Homopus areolatus(THUNBERG) had been marked, work on the latter starting in 1979. The tortoise population was estimated at 260 ca. 10 ha-1), half being P. geometricus. Twenty P. geometricus were lost to predators, a bush-cutting machine and emigration. Twelve further P. geometricus areas have been identified, two of which have been formed into reserves. A large (3 000 ha) private nature reserve established in 1973 north ofPaarl hold the largest surviving population.

Free-living ixodid ticks were collected monthly from August 1988 to July 1993 from the vegetation of landscape zones 17 (Sclerocarya caffra/Acacia nigrescens Savanna) and 4 (Thickets of the Sabie and Crocodile Rivers) in the south-east and south-west of the Kruger National Park respectively, and parasitic ticks from scrub hares in the latter landscape zone. Total tick collections from the vegetation of both landscape zones were lowest in the year following the drought year of August 1991 to July 1992, while the tick burdens of the scrub hares were lowest during the drought year itself.
