CHILD G. (1971, Botswana Notes & Records III) reviewed publications of a scientific and general nature dealing with wildlife and related topics in Botswana. The publications are the results of surveys and research carried out by members of the department and independent research workers who are utilising the opportunities for research in the field of wildlife or related subjects. A number of pu...

ii " Wildlife Working Reports frequently contain preliminary data, so conclusions based on these may be subject to change. Working Reports receive limited review. They may be cited in publications, but their manuscript status should be noted. Copies may be obtained, depending upon supply, from the Ministry of Environment, Lands and Parks, Wildlife Branch, 780 Blanshard Street, Victoria, B.C., V...

The striped hyena is an enigmatic species that little studied. It mainly found in semiarid and arid regions described as elusive, cryptic, nocturnal, solitary. global distribution disjunct, the suffers from human persecution. However, specific communities consider them to be commensals. Owing their scavenging behavior, hyenas are disproportionately involved vehicular-wildlife incidents, most of...

It has been observed empirically that each coe cient in a Parks-McClellan lter converges to a steady state value as the lter length increases. This suggests the possibility of obtaining lters that are near optimal while "re-using" lter coe cients from shorter lters in the design of longer lters. In the context of approximate processing this then allows a ltering operation to be done in stages. ...

Zoonoses involve infections and infestations transmissible from animals to humans. Zoonoses are a major global threat. Exposure to zoonotic pathogens exists in various settings including encroachment on nature; foreign travel; pet keeping; bushmeat consumption; attendance at zoological parks, petting zoos, school 'animal contact experiences', wildlife markets, circuses, and domesticated and exo...

It looks as if environment is an idea whose time has come. Newspapers give prominent display to environmental horror stories. Editorials demand better management of natural resources. Government statements on the need to preserve the environment are commonplace. Government programmes, too, are quite numerous and increasing in number day by day. There are massive schemes for afforestation, for i...

Samples and data were collected from twenty-eight female black rhinoceroses (Diceros bicornis) during translocation efforts carried out by the Department of National Parks and Wildlife Management in Zimbabwe. Biological data were collected, cytological examination of vaginal smears was performed, and serum concentrations of follicle stimulating hormone, luteinizing hormone, progesterone, oestri...

How urbanization shapes population genomic diversity and evolution of urban wildlife is largely unexplored. We investigated the impact of urbanization on white-footed mice,Peromyscus leucopus,in the New York City (NYC) metropolitan area using coalescent-based simulations to infer demographic history from the site-frequency spectrum. We assigned individuals to evolutionary clusters and then infe...

N agencies and public health organizations collaboratively addressed cyanobacteria issues for the first time after two dogs died within hours of drinking water from a small private lake south of Omaha on May 4, 2004. A water sample and a necropsy revealed that the dog deaths were due to high concentrations of the cyanobacteria toxin Microcystin LR. Meetings were held between the Nebraska Depart...

We report a case study, where we have established the identity from a challenging biological sample of a deceased tigress by parentage analysis. A wildlife crime was committed in one of the zoological parks in India in the year 2000, where one young tigress was killed for its claws. This was of media interest for several days and remained an unsolved case for four years. A framed claw and decom...
