What is the most significant implication of Boris and Svetlaya's successful reunion and mating for Amur tiger conservation strategies?
What is the most significant implication of Boris and Svetlaya's successful reunion and mating for Amur tiger conservation strategies?
- It confirms the necessity of continuous human intervention in the mating process of rescued tigers.
- It demonstrates the limited viability of conservation centers in preparing tigers for life in the wild.
- It suggests that releasing unrelated, rescued tigers into separate areas can lead to successful population restoration. (correct)
- It highlights the importance of providing supplementary food sources after releasing tigers to ensure their initial survival
Why might the conservation center have chosen to release Boris and Svetlaya in separate locations more than 100 miles apart?
Why might the conservation center have chosen to release Boris and Svetlaya in separate locations more than 100 miles apart?
- To ensure minimal competition between the two tigers for resources, thus maximizing individual survival rates.
- To study the effects of geographical separation on the tigers' social behavior before allowing them to interact.
- To test the tigers' ability to adapt to different environments and prey availability.
- To encourage the tigers to establish territories independently and potentially expand the species' distribution. (correct)
Considering the Amur tiger's habitat and behavior, which factor presents the greatest ongoing challenge to their long-term survival, despite increased numbers?
Considering the Amur tiger's habitat and behavior, which factor presents the greatest ongoing challenge to their long-term survival, despite increased numbers?
- The genetic consequences of a small population size, leading to reduced genetic diversity. (correct)
- The risk of disease outbreaks due to increased interaction among tiger populations
- The natural fluctuations in temperature extremes, impacting their hunting efficiency.
- The competition with other predator species for limited prey within their territory.

Study Notes
- Boris and Svetlaya, two rescued Amur tigers, reunited as mates in Siberia after being separated for over a year across a distance of 100 miles.
Background
- In 2014, Boris and Svetlaya, unrelated orphaned cubs aged 3-5 months, were brought to a conservation center in Siberia.
- They were raised with minimal human contact in an environment that mimicked the wild.
- To develop hunting instincts, the tigers were given live prey like rabbits and pheasants.
- At 18 months old, they were released into separate areas in the Sikhote-Alin mountains, over 100 miles apart.
- The separation aimed to spread the endangered tiger population across a wider area.
Reunion
- Wildlife Conservation Society (WCF) researchers monitored Boris and Svetlaya.
- A year post-release, Boris traveled north in a straight line towards Svetlaya's location.
- The tigers reunited, and six months later, Svetlaya had a litter of cubs.
- The findings were published in the Journal of Wildlife Management in November 2024.
- Using rescued cats to restore tiger populations in the wild had not been attempted before.
- Boris and Svetlaya’s success could make the rescue strategy a viable option.
Other Tigers
- Another rescued tiger named Zolushka was released into the wild and paired with a wild tiger; they also had cubs.
- Dale Miquelle of the WCS referred to it as “Cinderella’s prince showed up, and they lived happily ever after."
Amur Tigers
- Amur tigers, also known as Siberian tigers, are the largest tiger subspecies.
- They are native to eastern Russia and parts of China.
- They have thick, pale orange coats with dark stripes.
- The tigers camouflage well in snowy landscapes and tolerate temperatures as low as -50°F (-46°C).
- As solitary hunters, they require large areas to search for prey like deer and wild boar.
- Due to poaching and habitat loss, Amur tigers were once close to extinction, but conservation efforts have increased their numbers to about 500 in the wild.
- While still endangered, renewed hope exists for the species' preservation.

Description
Two rescued Amur tigers, Boris and Svetlaya, reunited in Siberia after a year-long separation. Raised in a conservation center and released 100 miles apart, Boris journeyed to Svetlaya, leading to a successful mating and the birth of cubs, contributing to the endangered tiger population.
