The results shed light on how different habitats are used by some of Tanzania's most elusive meat eaters, such as the leopard.
Scientists from the Zoological Society of London (ZSL), the Wildlife Conservation Society (WCS) and the Tanzania Wildlife Research Institute (TAWIRI) carried out the largest survey of Tanzania's carnivores, using a novel approach making use of over 400 camera trap locations.
The research reveals that many species, including the leopard, are particularly fussy about where they live, actively avoiding certain areas. Surprisingly, all the species surveyed tended to avoid croplands, suggesting that habitat conversion to agricultural land could have serious implications for carnivore distribution.
"Camera traps provide a fantastic opportunity to gain knowledge on habitat use and spatial distribution of otherwise elusive and poorly known species. This methodology represents a powerful tool that can inform national and site-based wildlife managers and policy makers as well as international agreements on conservation," says Dr Sarah Durant from ZSL.
Until now, many of the species had been under reported because of their nocturnal habits, or because they live in heavily forested areas. The strength of the technique to document habitat preference of elusive species is highlighted by camera trap observations of bushy tailed mongooses – including the first ever records of this species from one of the most visited areas in the country.
These data can also be used to understand how Tanzania's carnivores may respond to habitat changes caused as a result of environmental change.
"Carnivores are generally thought to be relatively tolerant to land conversion, yet our study suggests that they may be more sensitive to development than previously thought, and that protected areas need to be sufficiently large to ensure that these charismatic animals will roam in Tanzania for the decades to come,' says Dr Nathalie Pettorelli from ZSL.
She adds: "All species were affected by rivers and habitat, and the analysis provides important information relevant to the examination of future impacts of climate change."
The project continues to map carnivore distribution across the country, working closely with the wildlife authorities to support local conservationists and to generate information that is used to inform conservation planning.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
