Representatives from a group of organizations, including the Russian Academy of Sciences Institute of Biology and Soils, the Wildlife Conservation Society (WCS) and the Zoological Society of London (ZSL) captured the female in a remote location in south-west Primorye as part of their work to save the critically endangered leopard. The animal was tranquilized and an extensive and high-tech medical examination undertaken by the veterinary team.
Alexei Kostyria, biologist from the Institute of Biology and Soils in Vladivostok and co-leader of the project, commented, “This capture represents a new benchmark in assessing health of wild animals in Russia. We have brought together top experts from Russia and around the world and taken state-of-the-art equipment deep into the taiga to conduct medical assessments of the Far Eastern leopard. We have an unprecedented level of collaboration and remarkable effort that is essential if we are to save this critically endangered leopard.”
Kostyria’s counterpart, John Goodrich of the Wildlife Conservation Society, commented, “Catching this female was a big step forward in our efforts to understand the status of this population, and to better define necessary conservation actions needed to conserve this population.”
There are estimated to be between 24 and 32 Amur leopards living in the wild, making this population the rarest big cat on the planet. The animals are found in a corner of the Russian Far East on the Chinese border, in an area where their range is restricted by human activity. As the wild population is so small, it is likely that inbreeding (breeding between close relatives) is taking place and it is important to find out if this is having damaging effects on the cats in order to plan conservation action for the future. The Wildlife Conservation Society and the Zoological Society of London are working with local organizations to initiate a wildlife health monitoring program involving leopards and other wildlife in the region.
Initial findings from the veterinary examination of the leopard include the presence of a heart murmur, which could be indicative of inbreeding depression. Remarkably given the remote location, the team was able to capture footage of the heart, using a portable sonogram device, which has already been sent out for review by heart specialists. Further results are expected once laboratory analysis has been carried out, which will provide more information about the reproductive condition of the leopard as well as any illnesses or parasites that she may have been suffering from.
The Wildlife Conservation Society - Since 1895, the Wildlife Conservation Society (WCS) has worked to save wildlife and wild lands around the globe. Today WCS has field staff at work in over 60 nations, protecting many of the last wild places left on our planet. To bring the mission home, the Bronx Zoo based WCS is distinguished as the only global conservation organization that also operates the world's largest system of urban wildlife parks, educating more than 4 million zoo and aquarium visitors each year about the importance of wildlife conservation.
Founded in 1826, the Zoological Society of London (ZSL) is an international scientific, conservation and educational charity: our key role is the conservation of animals and their habitats. ZSL runs London Zoo and Whipsnade Wild Animal Park, carries out scientific research in the Institute of Zoology and is actively involved in field conservation in other countries worldwide. www.zsl.org.
ZSL and WCS are key members of ALTA (the Amur Leopard and Tiger Alliance), a consortium of conservation organisations working in partnership to protect the Amur leopard and tiger; information on ALTA’s Amur leopard programme can be found at www.amur-leopard.org
The Amur leopard (Panthera pardus orientalis), is listed as Critically Endangered on the IUCN Red List. There are currently estimated to be between 25 – 34 Amur leopards left in the wild, distributed in south-west Primorskii Krai, between Vladivostok and the Sino-Russian border. Male leopards can weigh up to 50kg, females as little as 35kg, and they are carnivorous, feeding mainly on deer. The leopard inhabits mixed forest environments and has long fur to help it withstand the freezing weather.
There are currently approximately 130 Amur leopards held in zoos throughout Europe and Russia; all are part of a conservation breeding programme coordinated by ZSL and Moscow Zoo.
Funding for the capture and medical assessment work was provided by the National Fish and Wildlife Foundation’s Save the Tiger Fund, the Homeland Fund, the Darwin Initiative, the Lucie Bergers Foundation, The US Fish and Wildlife Service’s Rhino-Tiger Fund, AMUR, and Wildlife Vets International. The Darwin Initiative is a small grants programme that aims to promote biodiversity conservation and sustainable use of resources around the world. The Initiative is funded and administered by the UK Department for Environment, Food and Rural Affairs, (Defra). www.darwin.gov.uk

Controlling electronic current is essential to modern electronics, as data and signals are transferred by streams of electrons which are controlled at high speed. Demands on transmission speeds are also increasing as technology develops. Scientists from the Chair of Laser Physics and the Chair of Applied Physics at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have succeeded in switching on a current with a desired direction in graphene using a single laser pulse within a femtosecond ¬¬ – a femtosecond corresponds to the millionth part of a billionth of a second. This is more than a thousand times faster compared to the most efficient transistors today.
Graphene is up to the job
At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.
Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...
Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
