The Amur tiger is currently confronted with challenges of anthropogenic development, leading to its population becoming fragmented into two geographically isolated groups: smaller and larger ones. Small and isolated populations frequently face a greater extinction risk, yet the small tiger population's genetic status and survival potential have not been assessed. Here, a total of 210 samples of suspected Amur tiger feces were collected from this small population, and the genetic background and population survival potentials were assessed by using 14 microsatellite loci.

- A study on the eastern water bat in the Russian Far East involved DNA barcoding and chromosomal analysis of captured specimens.
- Low nucleotide variability was found among the barcoding results for 18 out of 19 bats, indicating dominance of a single haplotype.
- The chromosomal analysis identified specific characteristics, including a first-time description of NOR localization, which differs from closely related species and shows notable intraspecific variability in heterochromatin distribution.
Article Synopsis
- Population dispersal and migration of Amur tigers in the northern Changbai mountain region reveal habitat expansion and reduced inbreeding, indicating a healthier population.
- The study shows that Amur tigers are migrating westward at a rate of approximately 12.83 km every three years, highlighting potential migration between populations in China and southwest Primorye, Russia.
- Findings emphasize the urgent need for habitat restoration and conservation measures, including building corridors to facilitate movement and promote international cooperation for tiger preservation.
