Using Animal Behavior Data To Better Inform Mathematical Models Of Animal Movements
2013-10-16 15:31:44

Max-Planck-Gesellschaft Many animals are adapting to human encroachment of their natural habitats. Carnivores in particular require territories of sufficient size and so are often forced to move between numerous small habitat patches. To date, scientists often use mathematical models to predict these important routes, but fishers fitted with GPS sensors are now showing that their calculations may be missing the mark if they ignore animal behavior. Corridors are spaces that receive too...

Study considers how to manage epidemics in information blackouts When foot-and-mouth disease swept through the British countryside in early 2001, more than 10 million sheep, cattle and pigs were slaughtered to control the disease. Despite the devastation, the disease was contained within ten months in part owing to the availability in that country of finely detailed farm data, which enabled mathematical modelers to make accurate predictions about the spread of the disease and suggest...

The world can deliver sudden and nasty shocks. Economies can crash, fisheries can collapse, and climates can pass tipping points. Providing early warning of such changes currently requires the collection of enormous and often prohibitive amounts of data. A new method developed by Steven Lade from the Max-Planck-Institute for the Physics of Complex Systems in Germany and Thilo Gross from the University of Bristol in the UK could change this. In a paper published in the open-access journal PLoS...

Unemployment time series in Spain behave in a chaotic way according to a study at the University of Seville. Such chaos demonstrates the complex and unpredictable nature of the Spanish labor market in the long run. However, short term patterns can be predicted using complex mathematical models. "Using mathematical techniques we have found evidence of chaos in unemployment time series in Spain. In theory, this explains why unemployment trends are so unstable," outlines Elena Olmedo,...

First it was chess. Then it was Jeopardy. Now computers are at it again, but this time they are trying to automate the scientific process itself. An interdisciplinary team of scientists at Vanderbilt University, Cornell University and CFD Research Corporation, Inc., has taken a major step toward this goal by demonstrating that a computer can analyze raw experimental data from a biological system and derive the basic mathematical equations that describe the way the system operates....

New model for speech and sound recognition People are adept at recognizing sensations such as sounds or smells, even when many stimuli appear simultaneously. But how the association works between the current event and memory is still poorly understood. Scientists at the Bernstein Center and the Ludwig-Maximilians Universität (LMU) München have developed a mathematical model that accurately mimics this process with little computational effort and may explain...

The instability of large, complex societies is a predictable phenomenon, according to a new mathematical model that explores the emergence of early human societies via warfare. Capturing hundreds of years of human history, the model reveals the dynamical nature of societies, which can be difficult to uncover in archaeological data. The research, led Sergey Gavrilets, associate director for scientific activities at the National Institute for Mathematical and Biological Synthesis and a...
