What complex ecological consideration might have prompted researchers to initially separate Boris and Svetlaya by over 100 miles after their release into the wild?
What complex ecological consideration might have prompted researchers to initially separate Boris and Svetlaya by over 100 miles after their release into the wild?
- To minimize potential inbreeding by ensuring they would not immediately encounter each other, thus promoting genetic diversity within the broader Amur tiger population. (correct)
- To observe whether the orphaned tigers could adapt to different regional prey densities and environmental conditions during their initial period of reintegration.
- To prevent immediate competition for resources in a concentrated area, allowing each tiger to establish a territory and avoid depleting local prey populations.
- To encourage the tigers to develop stronger hunting skills independently before forming a pair bond.
Considering the broader implications of the Boris and Svetlaya case, which of the following represents the most significant advancement in conservation strategies for endangered species?
Considering the broader implications of the Boris and Svetlaya case, which of the following represents the most significant advancement in conservation strategies for endangered species?
- The use of live prey to cultivate hunting behaviors in captive animals, proving that natural instincts can be nurtured through targeted intervention.
- The verification of trail cameras as reliable tools for monitoring animal behavior in remote and challenging environments.
- The successful integration of orphaned animals into the wild, indicating that early human intervention does not preclude the potential for natural behaviors.
- The demonstration that rescued animals can successfully reproduce in their natural habitat, suggesting that reintroduction programs can effectively contribute to population recovery. (correct)
What ethical challenge is most directly addressed by raising rescued tiger cubs with minimal human contact and providing live prey to develop their hunting instincts?
What ethical challenge is most directly addressed by raising rescued tiger cubs with minimal human contact and providing live prey to develop their hunting instincts?
- Balancing the need for animal welfare during rehabilitation with the necessity of preparing them for survival in the wild, where dependence on humans would be detrimental. (correct)
- Avoiding the potential for habituation, where animals become overly comfortable with human presence, thereby reducing their fear and altering their natural behavior.
- Ensuring the genetic purity of the species by preventing hybridization with other subspecies of tigers.
- Preventing the spread of diseases from captive populations to wild ones, which could devastate local ecosystems.

Study Notes
- Boris and Svetlaya, two rescued Amur tigers in Siberia, Russia, reunited as mates after being separated for over a year.
- They were brought together in 2014 as cubs.
Rescue and Rehabilitation
- Boris and Svetlaya were unrelated orphans, rescued at 3 to 5 months old.
- They were taken to the same conservation center in Siberia.
- The cubs were raised with minimal human contact in an environment resembling the wild.
- The tigers were given live prey, such as rabbits and pheasants, to develop their hunting instincts.
Release and Reunion
- At 18 months old, Boris and Svetlaya were released into their natural habitat in the Sikhote-Alin mountains.
- To spread the endangered species, they were released in separate areas over 100 miles (160 km) apart.
- Researchers from the Wildlife Conservation Society (WCF) monitored the tigers.
- A year after release, Boris walked north towards Svetlaya and they reunited.
- Six months after reuniting, Svetlaya gave birth to a litter of cubs.
Conservation Strategy
- The scientists published their findings in the Journal of Wildlife Management in November 2024.
- The strategy of using rescued cats to restore tiger populations in the wild had not been tried before.
- Boris and Svetlaya’s success could make their reunion a viable conservation option.
Other Success Stories
- Another rescued tiger named Zolushka (Cinderella) was released into the wild.
- An unknown male tiger appeared and she produced a litter of cubs with him.
Amur Tiger Facts
- Amur tigers, also known as Siberian tigers, are the largest tiger subspecies.
- They are native to the forests of eastern Russia and parts of China.
- They have thick, pale orange coats with dark stripes.
- These tigers can survive temperatures as low as -50°F (-46°C).
- Solitary hunters, they cover large areas for prey like deer and wild boar.
- Amur tigers were once on the brink of extinction due to poaching and habitat loss.
- Conservation efforts have increased their numbers to about 500 in the wild.
- The tigers remain endangered, but there is renewed hope for the species' preservation.

Description
Two rescued Amur tigers, Boris and Svetlaya, were reunited in Siberia after being separated for over a year. They were rescued as cubs and raised in a conservation center to develop their hunting instincts before being released into the wild. After release, Boris traveled over 100 miles to reunite with Svetlaya, and they later had cubs.
