The yak (Bos grunniens), also known as the Tartary ox, grunting ox, [1] hairy cattle, [2] or domestic yak, is a species of long-haired domesticated cattle found throughout the Himalayan region, the Tibetan Plateau, Tajikistan, the Pamir Mountains, and as …

2021年8月9日 · The significant reduction in heat production of yaks during winter might result from their adaptation to low oxygen concentrations in the air, the cold environment, and the long-term under nutrition prevalent in the six-months-long cold season of the Tibetan plateau .

When the conditions are cold, for example at night and in snowstorms, yaks protect themselves from the cold by huddling together, and positioning the calves in the center, where it is warmer. When there is snow on the ground, yaks use their horns to uncover the plants below.

2012年7月1日 · Comparison between yak and the closely related low-altitude cattle (Bos taurus) is informative in studying animal adaptation to high altitude. Here, we present the draft genome sequence of a...

2025年1月18日 · The wild yak, a symbol of resilience and survival in extreme environments, is an intriguing subject for study due to its unique adaptations and behaviors. These majestic creatures are integral to the ecosystems they inhabit, providing insights into high-altitude biodiversity and climate adaptation.

2024年3月7日 · This study aims to delve deeper into the genetic basis of yak adaptation to high-altitude environments, focusing on the digestive enzyme genes isolated from Yak genomes and examining the...

2018年5月4日 · The absence of sweating in the yak enhances cold tolerance by condensing the heat dissipation away from body but makes them more susceptible to heat stress (Krishnan et al. 2016). Further, coat is also well suited to insulate the animal from cold, protecting it from heat and repelling moisture (Wiener et al. 2003 ).

The yak's adaptability to extreme cold makes it an invaluable companion for people living at elevations where few other animals can thrive. Their grazing habits also help manage alpine grasslands without overexploiting resources—a key factor in maintaining ecological balance in fragile mountainous ecosystems.

Yak have many characteristics and attributes that must be regarded as adaptations to many factors: extreme cold; high altitude with low oxygen content of the air and high solar radiation; difficult, often treacherous terrain; and cyclical nutrition with short growing seasons for grazing herbage as well as a variety of herbage.

2021年4月20日 · Yaks shifted enterotypes in response to dietary change between warm and cold seasons to best utilize nitrogen and energy, in particular in the harsh cold season. Our findings provide insights...
