Carnivore species are predicted to be at increased extinction risk from human population growth

13.07.2004


Research published online today reveals that many of the world’s carnivores are at greater risk of extinction than previously thought. Close to a quarter of the world’s mammals are already at high risk of extinction. Any chance of reversing this trend depends on understanding what makes some species vulnerable and others resilient. And that depends on being able to predict extinction risk.

Now, a new model based on a phylogenetic analysis of the mammalian order Carnivora, described online in the open-access journal PLoS Biology, could help focus conservation efforts by predicting which species face greatest risk. The model predicts risk based on the density of local human populations combined with various traits of different species of carnivores, such as their population density, gestation length, and habitat range. The research, by Marcel Cardillo and other conservation scientists from London, Virginia and the IUCN, finds that combining data on species’ biology with that on human population densities yields better predictions of extinction risk than either set of data can alone. For example, a species with a long gestation period that lives close to densely populated human areas are at greater risk than species with similar gestation periods that live near sparsely populated areas. When under heavy pressure from people--whether hunting or habitat loss--species with long gestation periods can’t repopulate fast enough and become endangered.

Based on projected human population growth, the researchers predict that many carnivore species will join the list of endangered species list by 2030. Most of these species live in Africa, where human populations are growing faster than the global average. Based on the researchers’ projections, some species currently considered low conservation priorities--such as members of the weasel-like viverrid family--could soon become endangered.



Altogether, these results indicate that as human population pressures increase, it becomes ever more important to take account of each species’ biological traits to best predict which species will become most vulnerable. While most conservation efforts focus on damage control, Cardillo and colleagues argue for interceding before a species reaches the brink of extinction. "There is no room for complacency about the security of species," the authors warn, "simply because they are not currently considered threatened."

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
