Mother lode of jaguars discovered in Bolivia park

Bolivia’s sprawling Kaa-Iya Gran Chaco National Park, known for some of the world’s highest densities of ticks, may now lay claim to another superlative: more jaguars than any protected area on earth. According to a recent study by the New York-based Wildlife Conservation Society (WCS) and other groups, published in the Journal of Zoology, as many as 1,000 of these elusive big cats may call Kaa-Iya home.

Using methodologies developed by WCS to count tigers in India, the researchers employed remote camera "traps" to photograph jaguars, recording each animal’s unique spotting pattern. Through a statistical analysis that counts each animal re-photographed within a given territory, an accurate population estimate can be determined.

"Our results show that the Chaco is rich with jaguars – and Kaa-Iya in fact probably contains the largest population recorded in any protected area," said WCS conservationist, Dr. Andrew Noss, who co-authored the paper along with representatives of Fundación Ivi-Iyambae, Captinía de Alto y Bajo Isoso, a Bolivia-based indigenous group that helps manage the park.



At 34,000 square km (13,281 square miles) – Kaa-Iya Park is larger than Massachusetts and Connecticut combined. The park also contains Latin America’s highest diversity of large mammals, including the highly endangered Chacoan guanaco, eight species of armadillo (including one that weighs 80 pounds), and the Chacoan peccary – a pig-like animal once believed to be extinct. It is also known for its extreme heat, endless forests of thorn scrub, and untold numbers of ticks. Created in 1995, it is the only park in South America established at the initiative of a Native American organization, which have taken on a central role in its protection.

The authors warn that fragmentation of habitat, both within the Chaco and other areas, coupled with poaching, continue to threaten jaguars throughout their range. The researchers are now looking at how to better protect jaguars both in and out of the park – part of a long-term WCS campaign to safeguard populations throughout Latin America.

Im Focus: Successfully Tested in Praxis: Bidirectional Sensor Technology Optimizes Laser Material Deposition

The quality of additively manufactured components depends not only on the manufacturing process, but also on the inline process control. The process control ensures a reliable coating process because it detects deviations from the target geometry immediately. At LASER World of PHOTONICS 2019, the Fraunhofer Institute for Laser Technology ILT will be demonstrating how well bi-directional sensor technology can already be used for Laser Material Deposition (LMD) in combination with commercial optics at booth A2.431.

Fraunhofer ILT has been developing optical sensor technology specifically for production measurement technology for around 10 years. In particular, its »bd-1«...

The well-known representation of chemical elements is just one example of how objects can be arranged and classified

The periodic table of elements that most chemistry books depict is only one special case. This tabular overview of the chemical elements, which goes back to...

Im Focus: MPSD team discovers light-induced ferroelectricity in strontium titanate

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.

Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...

Im Focus: Determining the Earth’s gravity field more accurately than ever before

Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.

The Earth’s gravity fluctuates from place to place. Geodesists use this phenomenon to observe geodynamic and climatological processes. Using...

Im Focus: Tube anemone has the largest animal mitochondrial genome ever sequenced

Discovery by Brazilian and US researchers could change the classification of two species, which appear more akin to jellyfish than was thought.

The tube anemone Isarachnanthus nocturnus is only 15 cm long but has the largest mitochondrial genome of any animal sequenced to date, with 80,923 base pairs....
