Report lists top 20 most-vulnerable African carnivores

02.02.2006


From lions to honey badgers are ranked by conservationists



It may still be "king of the beasts," but the African lion’s kingdom is dwindling, according to a new report released by the New York-based Wildlife Conservation Society (WCS) that says these emblematic big cats have disappeared from 82 percent of their historic distribution over the past several decades. The 200-page report looked at the conservation status of the 20 largest species of African carnivores and examined priorities to help ensure that they persist on the continent.

WCS scientists ranked all 20 species using a variety of external factors, from the state of current knowledge on the species, to the threats facing each of them. They also looked at which areas in Africa have retained their full complement of large carnivore species and which areas need more conservation action.


Populations of the lion, listed in the report as "most vulnerable" have dropped steadily in recent decades, primarily due to conflicts with humans, destruction of habitat, and the loss of prey, according to the report. Also making the most-vulnerable list are cheetahs and African wild dogs, which have vanished from 75 and 89 percent of their historical habitat respectively, and Ethiopian wolves which have vanished from an astonishing 98 percent of their range. Other species of concern included the leopard, spotted hyena, and golden cat, all of which suffer from the combined key threats of habitat loss and conflict with people over predation on domestic animals.

By contrast, a handful of species seem to thrive among humans, including the African civet and several species of jackals. While these species also prey on livestock and poultry, their adaptability to a variety of habitats makes them less vulnerable to long-term population declines. Little was known about the conservation status of other species such as the aardwolf and honey badger and the report calls for greater research effort on these little-known carnivores.

The authors of the report say that while such well-known species as lions enjoy a relative wealth of conservation and research-based initiatives, there still remains a range-wide lack of knowledge of many carnivores. In addition, many research programs are geographically biased toward East and Southern Africa, sometimes at odds with the urgent need for increased conservation action in other parts of Africa.

"Africa is world famous for its variety of carnivore species from lions to hyenas," said Dr. Luke Hunter a co-author, who also runs WCS’s Global Carnivore Program. "These animals play a key role in the health of ecosystems, and represent all that is wild about Africa. This report lays out a framework for conservationists to better understand both the threats facing these animals, and the conservation action needed to ensure their survival."

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
