This is the first study to show the genetic identity of the Altai-Sayan population of the forest reindeer of the Kuznetsk Alatau (Rangifer tarandus valentinae). The population is characterized by the existence of unique mitochondrial lines, the absence of signs of introgression of domestic rein deer mtDNA, as well as a low level of genetic diversity. In the sample studied, only two nucleotide substitutions (both of them transitions) were revealed, the nucleotide diversity (0.0015 ± 0.00136) was almost ten times lower than in most populations of wild reindeer in Russia and was comparable only with that of some wild reindeer populations of Norway and Svalbard. The haplotype diversity (h) was also relatively low (0.615 ± 0.102).

Article Synopsis
- Caring for newborns limits mammalian females' ability to gather resources, especially during the energy-demanding early lactation period.
- Different ungulates have developed various strategies for protecting their vulnerable newborns, from staying hidden to being mobile, which can influence their mothers' movement patterns.
- A study of 54 populations of 23 ungulate species shows that maternal movements are affected by the resource availability and type of neonatal strategy, highlighting the importance of these tactics in understanding how species adapt to environmental changes.

Extreme weather events are becoming more frequent, with poorly known consequences for wildlife. In December 2021, an atmospheric river brought record-shattering amounts of rain and snow to interior Alaska, creating conditions expected to cause mass mortality in grazing ungulate populations that need to access ground forage. We characterized snowpack conditions following the storm and used a 36-year monitoring dataset to quantify impacts on caribou (Rangifer tarandus) and their primary predator, wolves (Canis lupus).

Article Synopsis
- Climate change is impacting deer populations by pushing their physiological limits, where short-term individual adaptations may lead to long-term evolutionary changes.
- The review analyzed 218 studies from 2000-2022, focusing on how factors like temperature and rainfall affect various deer species across North America, Europe, and Asia, indicating that some may benefit from milder winters but suffer during hot summers.
- Important findings include that deer exhibit behavioral and physiological adaptations in response to climate variability, yet local factors like population density can influence their resilience, with significant knowledge gaps remaining in understanding impacts of extreme weather events.

Reindeer, called caribou in North America, has a circumpolar distribution and all extant populations belong to the same species (). It has survived the Holocene thanks to its immense adaptability and successful coexistence with humans in different forms of hunting and herding cultures. Here, we examine the paternal and maternal history of based on robust Y-chromosomal and mitochondrial DNA (mtDNA) trees representing Eurasian tundra reindeer, Finnish forest reindeer, Svalbard reindeer, Alaska tundra caribou, and woodland caribou.
