Comparison of cardiopulmonary effects of etorphine and thiafentanil administered as sole agents for immobilization of impala (Aepyceros melampus)

Growth and development of the prenatal impala has been described by Fairall (1969) and Roettcher, Hoffman and Kayanja (1970) while weights and measurements of the mature animal have been reported by Sachs (1967) and Talbot and McCulloch (1965). Child (1964) has investigated growth in this species. This paper serves as a baseline for comparison of future changes in morphology of the species, as the animals were all obtained at the beginning of the culling programme.

Two full-grown impala rams Aepyceros melampus were shot on 1978.01.07 in the Pafuri area of the Kruger National Park, Republic of South Africa. The carcasses were placed in enclosures 2,7 km apart and used to monitor the visitation patterns of insects. Collections of insects were made at four-hourly intervals for the first six days after placement of the carcasses, and thereafter every six hours up to the eleventh and final day. A figure is given to describe changes in the physical attributes of the carcasses through time. Twelve figures depict the patterns of arrival of insects at the carrion habitat. Species from the following families are represented: Cleridae, Dermestidae, Histeridae, Scarabaeidae, Silphidae, Staphylinidae, Trogidae (Coleoptera); Calliphoridae, Muscidae, Piophilidae, Sepsidae (Diptera); Diapriidae and Formicidae (Hymenoptera). The results indicate that species have distinctive periods of abundance and presents an overall picture of insect succession at carrion.

Aepyceros Melampus

A paint-spraying device was employed for marking wild African mammals without capture. This relatively inexpensive marking technique, which had originally been used for the marking of American desert bighorn sheep at drinking places, was also successfully applied in the marking of impala, Aepyceros melampus, blue wildebeest, Connochaetes taurinus, Burchell's zebra, Equus burchellii antiquorum aud the African elephant, Loxodonta africana. The apparatus used differs in some respects from that originally described by Hanson (1964). It was also used for the marking of animals from a mobile unit and away from fixed drinking places. This paper is based on a part of a thesis, submitted to the University of Pretoria in partial fulfilment of the requirements for the degree of D.Sc. (Wildlife Management).

Aepyceros Melampus

Sperm must remain motile in order to reach and penetrate the ovum and defects in the ultrastructure of the tail can have an adverse influence on motility. Live spermatozoa were collected from the cauda epididymis of 64 impala rams in the Kruger National Park and studied by transmission electron microscopy to document sperm abnormalities. The following abnormalities of the flagellum were documented from micrographs: abnormal baseplate and neck attachments; neck vacuoles and displaced organelles; double or short flagella; bent flagella; principal-piece vacuoles; displaced axoneme and the Dag defect. The implications of these abnormalities for sperm motility are discussed.
