In order to reduce the stress response of animals in animal transportation, it is often used to feed the animals with sedative drugs combined with compound vitamin B. In this article, we will randomly divide 16 amur tiger into the control group and the experimental group. The drug intervention is carried out in the experimental group. The sedative is mainly dexmedetomidine, combined with compound vitamin B, while control group did not feed the drug. The urine of two groups of individuals was collected before and after transportation and the cortisol content in urine was determined by radioimmunoassay as an indication of stress. Finally, referring to the changes of cortisol level in amur tiger, we analyzed the effect of vitamin B6 combined with sedative drugs on the anti stress effect of amur tiger. The results showed that the cortisol level in the control group was significantly different (P < 0.05), but there was no significant difference in the cortisol level in the experimental group (P > 0.05). This kind of veterinary medicine which is mainly composed of sedative dexmedetomidine and vitamin B6 is obviously helpful for reducing the stress of the Amur tiger in transferred transportation.

Article Synopsis
- Population density is crucial for wildlife management, particularly in the Russian Far East, where methods like the FMP snow tracking are used to estimate ungulate densities and support Amur tiger conservation.
- Despite the effectiveness of FMP, reliability issues due to climate change and survey design challenges prompt the exploration of camera traps as an alternative for monitoring prey density, though their potential is still largely untested.
- A comparative study over three years found that, while both FMP and camera trap methods provided similar prey density estimates, discrepancies in prey biomass calculations highlight the need for caution in management decisions and suggest more research is necessary to improve estimation methods.

Inbreeding increases genome homozygosity within populations, which can exacerbate inbreeding depression by exposing homozygous deleterious alleles that are responsible for declines in fitness traits. In small populations, genetic purging that occurs under pressure of natural selection acts as an opposing force, contributing to a reduction of deleterious alleles. Both inbreeding and genetic purging are paramount in the field of conservation genomics.

Article Synopsis
- - Southwest Primorye is home to about 9% of the wild Amur tiger population, which has significantly recovered from fewer than 10 individuals in 1996 due to decades of conservation efforts.
- - A study using non-invasive genetic analysis found 32 Amur tigers and identified issues like low genetic diversity and signs of past population bottlenecks, raising concerns about inbreeding.
- - The findings underscore the necessity to create ecological corridors to connect to other tiger populations for improving genetic diversity and ensuring long-term conservation.

Article Synopsis
- The study examines the Siberian roe deer population in the Greater Khingan Mountains of Northeast China, emphasizing its role as an ecological indicator species and the importance of its living conditions for ecosystem balance.
- Researchers collected and analyzed 269 fecal samples over three years using advanced genetic techniques, identifying 244 individual deer and revealing high genetic diversity within the population.
- Despite the overall genetic health, the study indicated some populations are at risk, with evidence of genetic differentiation, potential inbreeding, and varying development potential among local deer populations.
