Kolkata, May 22, 2017: A new method developed by experts incorporates the time of the photo-capture to estimate abundance and spatial distribution of tigers and helps represent data closer to reality, a statement said on Monday.

Seventy percent of wild tigers are concentrated in less than six percent of remaining habitats worldwide. Science-based management is critical for tiger conservation. Spatial capture-recapture (SCR) model analysis is often used to estimate tiger abundance.

A new study led by Robert Dorazio of the United States Geological Survey, and co-authored by Ullas Karanth, Wildlife Conservation Society Director for Science in Asia, exploits all information provided by the SCR data, obtained using continuous-time recorders i.e. camera-traps.

Dates and times of animal detections are fundamental considerations to designing and implementing a conservation strategy.

Traditionally time-data is discarded during analysis despite availability of the information in camera-trap data.

The new model estimates the spatial distribution and abundance of animals by making full use of location of photo-capture data and time of photo-capture data – which is a significant advance from traditional SCR analysis which uses only location of photo-capture data.

Dorazio said: “Modeling photo-capture times of tigers and other large carnivores uses all of the information in the data and gives us a chance to learn more about the behaviors and movements of these animalsa” information that is crucial to their conservation.”

“We are now able to exactly incorporate the time of capture into the data analysis. This gives us more power to mimic nature in the sense of how tigers actually get ‘trapped’ in cameras, and how their movement, behavior, and space-use relate to time. This is a significant advance,” Karanth said.

The scientists illustrated this model by analysing spatial and temporal patterns evident in the camera-trap detections of tigers living in and around Nagarahole Tiger Reserve in Karnataka.

The study is published in the current issue of PLOS ONE journal. (IANS)

The program is inseparable from Mahalaya and has been going on for over six decades till date. The magic is induced by the popular Birendra Krishna Bhadra whose voice makes the recitation of the “Chandi Kavya” even more magnificent! He has been a legend and the dawn of Mahalaya turns insipid without the reverberating and enchanting voice of the legendary man.

Mahalaya will keep spreading the magic and setting the vigor of the greatest festival of the Bengalis- the Durga Puja, to worship the supreme Goddess, eternally.

June 06, 2017: NASA has chosen 12 astronauts out of a record-breaking 18,300 applications for upcoming space missions. An American of Indian descent, Raja Chari, has successfully earned his spot in the top 12.

The astronauts were selected on the basis of expertise, education, and physical tests. This batch of 12 astronauts is the largest group selected by NASA since two decades. The group consisting of 7 men and 5 women surpassed the minimum requirements of NASA.

Born in Waterloo, Iowa, Chari graduated from Air Force Academy in 1999 with a bachelor’s degree in Astronautical Engineering and Engineering Science. He went on to complete his master’s in Aeronautics and Astronautics from Massachusetts Institute of Technology. The astronaut is also a graduate of US Naval Test Pilot School.

Currently, Raja Chari is a Lieutenant Colonel in the US Air Force. He is the commander of 461st Flight Test Squadron and director of the F-35 Integrated Test Force at Edwards Air Force Base in California.

After Late Kalpana Chawla, Lt. Col. Raja Chari is the second Indian American astronaut chosen by NASA.

The 12 astronauts will have to go through two years of training. Upon completion, they will be assigned their missions ranging from research at the International Space Station, launching from American soil on spacecraft by private companies, to flying on deep space missions on NASA’s Orion Spacecraft.

The US Vice-President Mike Pence visited the Johnson Space Centre in Houston to announce and congratulate the new batch. Pence also said that President Trump is “fully committed” to NASA’s missions in space.
