Carnivores, livestock and people manage to share same space study finds

14.03.2013
In the southern Rift Valley of Kenya, the Maasai people, their livestock and a range of carnivores, including striped hyenas, spotted hyenas, lions and bat-eared foxes, are coexisting fairly happily according to a team of coupled human and natural systems researchers.
“I wouldn’t call the results surprising,” said Meredith Evans Wagner, a visiting scholar from the University of Florida in the Center for Systems Integration and Sustainability (CSIS) at Michigan State University and part of the research team. “Other research has shown that people and carnivores can coexist, but there is a large body of thought that believes carnivores need their own protected space to survive.”

The paper “Occupancy patterns and niche partitioning within a diverse carnivore community exposed to anthropogenic pressures” was recently published in Biological Conservation. Other authors are Paul Schuette and Scott Creel, of Montana State University, and Aaron Wagner, postdoctoral researcher in the BEACON Center for the Study of Evolution in Action at Michigan State.

The paper’s findings echo results of a study published in PNAS in September 2012 by Jianguo “Jack” Liu and Neil Carter of CSIS: namely that tigers and people are sharing the same space in Chitwan National Park in Nepal, albeit at different times.

Wagner and her colleagues spent just over two years documenting the carnivores of the southern Rift Valley, using motion-detecting camera traps to captures images of the creatures and people using four different areas of land: a conservation area with no human settlements, a grazing area that also had no human settlements, a permanent settlement area, and a buffer zone between the grazing and conservation areas that included seasonal human settlements.

While most of the results were expected – the majority of carnivore photos were taken after dark, most of the larger predators, such as lions and spotted hyenas, tended to be found in the conservation area that didn’t include any human settlements – there were some intriguing results.

“We found that while there were more striped hyenas in the conservation area, there were also striped hyenas in the buffer zone, close to the human settlement area,” Wagner explained. “The hyenas weren’t avoiding that area; they were using the settlement area as a resource in addition to hunting.”

When the Maasai slaughtered an animal for food, they throw the scraps out their back doors, which are at the edge of the buffer zone, where the striped hyenas were happy to eat them.

“Carnivores aren’t a problem for this group of Maasai,” Wagner said. “They’ve made a conscious decision to not hunt carnivores. If one of their livestock is killed by a carnivore, people don’t go out and kill a carnivore in retaliation. It’s a little bit unusual in that way. But in our study, we found that carnivores killing livestock didn’t happen a lot.”

“Wildlife is clearly driven away from the permanent settlement areas," said Aaron Wagner. "But the seasonal human migration out of the buffer zone keeps that area viable for wildlife. Numbers drop when the cattle and people move in, but the striped hyenas seem to have habits that allow them to compensate. They do scavenge around bomas [Maasai settlements] when the pickings are good, but they hunt, too. Even with the people around, there are enough prey left, or enough trickling in from the conservation area, that they have plenty to hunt. More often than not, when following a striped hyena that’s foraging (or playing at a den) at 3 a.m., there’s no indication that people are so close.”

The research was funded by the National Science Foundation, the Cincinnati Zoo and the Panthera Corporation.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
