During his first full-throttle "persistence hunt," the South African biologist Louis Liebenberg was working with bushmen in the Kalahari Desert in the early 1990s. Armed with handmade bows and arrows, the hunters had been stalking kudu—a nimble antelope, slightly smaller than an elk. When a young stag split off from the herd, the bushmen ran flat-out after it.
Inventé par le zoologiste amateur Louis Liedenberg, du Cap (Afrique du sud), le logiciel CyberTracker permet à tout un chacun d'inscrire des notes sur un PDA à propos d'une observation faite sur le terrain, et de l'indexer à partir de ses coordonnées GPS.
Satellite images and aerial surveys give some idea of wildlife populations and patterns of vegetation, but the best way of tracking changes in African national parks is still to go in on foot. But skilled scientists are not always on hand to perform surveys.
Take a look around you," says Abdulhadi Saleh al-Murri, declining a fourth pouring of Arab coffee with a shake of the thimble-sized cup. "As well as our host, at least 10 of the guests in this majlis are notable trackers. All of them are from the Murrah tribe. Half of them work with me in Riyadh."
New Zealand Surveyor: Palm computers for spatially referenced social surveys in upgrading informal settlements
Conditions in informal settlements are complex, at times violent, and continually changing. Managing these settlements in a way that will result in a functional, healthy urban environment constitutes a major challenge. Effective upgrading strategies require accurate, up-to-date social, economic and spatial information. This is especially so when the information is used for adjudication and titling. Moreover the information should be regarded as legitimate by settlement residents themselves.
Ancient skills and new technology end beach attacks by predicting where criminals will strike next - enabling cops to ambush them.
ANN ARBOR---Elementary school children in Ann Arbor, Melvindale, and Detroit are trekking through the wild---at least, the "wild" life around their schoolyards. With handheld computers at their side, these budding biologists are studying the biodiversity around their schools using software originally developed by professional animal trackers in Africa.
The program, called BioKIDS: Kids Inquiry of Diverse Species, is made possible through the cooperative efforts of the University of Michigan's School of Education and Museum of Zoology, and the Interagency Education Research Initiative (National Science Foundation, Department of Education and theNational Institute on Health). Uniting students, teachers, and biologists, BioKIDS allows students to use a variety of program-specific computer resources to explore how and why animals and humans interact. The students, employing the outdoors as their science lab, ultimately develop field guides for their fellow students to view.
It is a warm fall day, and a group of TPWD biologists is staring intently at a clue left on the muddy banks of the Neches River. A white note card pointing to a nearby animal track reads, "Who made this track?" Ideas race through the minds of the group members as they attempt to solve the mystery. The track is way too small to be an alligator, but too big to be a mink. There are five toes — with webbing — and nail marks showing. Could it really be? Yes, this track was left by one of Texas' most inconspicuous inhabitants — the Northern River Otter.
THE BEAR LIKED ACORNS, ESPECIALLY WHEN HE FOUND THEM CONVENIENTLY DROPPED ONTO THE SMOOTH DIRT PATH THAT WOUND BEHIND THE CAMP to the river. He also liked grubs -- and the wood pile in camp, with those tidy little chunks of tree all split up nice and paw-handy, made it easy for him. All he had to do was swipe a good rotty one up, hug it close and gnaw until the grubs nestling in the fibers popped out like candy into his mouth. And berries, of course -- who didn't like berries?
An armed reaction team, more staff and the help of a tracking organisation is what Table Mountain National Park (TMNP) says are just a few steps necessary to boost its unsatisfactory security measures - but it cannot implement them without more money. Since Friday, at least 15 muggings have been reported on Cape Town's mountain and a state of readiness security meeting will be held on September 17.
