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.

NewsGram brings to you latest new stories in India.

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)

Actress Anushka Sharma has joined hands with Discovery to promote a global awareness movement to save tigers from extinction.

Anushka Sharma will promote Project C.A.T: Conserving Acres for Tigers, aimed at raising awareness to preserve the habitat of the declining numbers of tigers in the wild.

Discovery has collaborated with World Wildlife Fund (WWF) for Project C.A.T, a statement said.

Anushka, who has consistently championed the cause of animal welfare and was recognised as PETA’s person of the year 2017, features in a video.

She says, “Tigers – the glorious wild cats are in real danger of getting extinct and they need our help.

“As a large predator, tigers are an umbrella species and play a critical role in ensuring that the delicate ecological balance in the wild is maintained. The current situation is a sad reflection of us as human beings.”

She believes everyone needs to reflect upon how they can contribute to make the world a better place to live in and “ensure that our future generations too can experience this magnificent creature”.

Karan Bajaj, Senior Vice President and General Manager – South Asia, Discovery Communications India, said: “We are excited to partner with Anushka Sharma to ignite awareness about tiger conservation and help promote the global movement to save them. We will use the collective power of our media brands to amplify the message of Tiger conservation.”
