The reproductive behaviour of the giant cricket Brachytrupes membranaceus (Drury) was investigated at Gobabeb in the Namib Desert. Reproduction takes place from January to March. During this period the male never leaves its hole; it digs a 'singing chamber' at the burrow entrance where it produces an ear-piercing song to aftract females. After mating, the male seals the female in an isolated branch at the end or the burrow; and then calls other females.
Staatsopgaardamme speel 'n belangrike rol in die watervoorsiening van mens en dier in Suidwes Afrika/Namibie. Benewens watervoorsiening kan hierdie watermassas ook benut word as bronne vir visontginning of kommersiele visboerdery.
As part of a wider study of Iinear dune dynamics, a series of photographs were taken of a secondary, barchanoid form on a 'complex' linear dune in the Namib Desert at regular intervals over one year from a strategic picket. These photographs show the response of the secondary dune to a seasonal wind regime.
The status and inter-pair distances of raptors nesting on the cliff of the Waterberg-Omuverume plateau were obtained from a helicopter survey. Evidence is presented indicating that the dramatic decline in numbers experienced by the Cape Vultures has been halted and probably reversed as a result of conservation action.
An annotated checklist of all raptors worded within the Skeleton Coast Park is given. Some extralimital species which may occasionally enter the park are also included. Sight and breeding records are listed per quarter degree square for each raptor species. A brief descriptionption of the major habitat types is given and a map of the area with quarter degree squares is included.
