No place like home: Africa's big cats show postcode preference

13.10.2009
The secret lives of some of Africa's iconic carnivores, including big cats, are revealed in a new study in Animal Conservation, today.

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.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
