Plateau pika

The plateau pika (Ochotona curzoniae), also known as the black-lipped pika, is a species of mammal in the pika family, Ochotonidae.
It is a small diurnal and non-hibernating mammal weighing about 140 g (4.9 oz) when fully grown. The animals are reddish tan on the top-side with more of a whitish yellow on their under-belly.
They prefer to live in elevations of 3,100 to 5,000 m (10,200 to 16,400 ft), mostly in the Tibetan Plateau, which is where the common name originates from. The species is found in China, India, and Nepal in high alpine deserts, steppe and meadows, as well as tropical and subtropical montane forests.
Plateau pikas are considered to be a keystone species as they play a role in recycling nutrients in soil, providing food to predators such as; foxes, weasels, falcons, Asia pole cat, upland buzzard, and owls. They also provide microhabitats by increasing plant richness and their burrows provides nests for small birds and reptiles.
According to the Chinese biologists who have studied the wildlife of the Hoh Xil (northern part of the Tibetan Plateau), plateau pikas are the favorite food of the area's brown bears. In addition to its role as a prey base, the plateau pika is important for soil health in meadows; the burrowing of the species helps to aerate the soil. The species is currently considered threatened, mostly due to aggressive poisoning campaigns by Chinese populations, predominantly to eliminate competition for food with livestock.
Plateau pikas have mating systems such as monogamous and polygynandrous groups, which contain about three males and 3 to 4 females per family along with their offspring. Females can produce 2 to 5 litters of about 2 to 7 offspring with a three-week interval in between each litter which is why this group of lagomorphs are known to have the fastest growth rates of their order. Their breeding season lasts from April to August and the young do not disperse in the year of birth. Males form hierarchies and females are usually philopatric forming reproductive alliances, helping each other in the care of their offspring, males also contribute in parental care when deterring a predator by emitting an alarm call. Pikas are social animals that live in families of two to five adults and their offspring. Males and females both contribute in protecting their family groups from intruders displaying aggressive behaviors towards others who are not part of their family.
Since plateau pikas live in such extremely cold environments and are a non-hibernating species, they have acquired physiological adaptations to better assist with their survival. These adaptations include their high resting metabolic rate and non- shivering thermogenesis along with the production of leptin which is a thermogenesis regulatory hormone.
Unlike hibernating mammals, plateau pikas do not merely rely on excess body fat to combat extremely cold climates. One important physiological adaptation is their ability to alter the type of their adipose tissue, from white to brown, which promotes non-shivering thermogenesis.
The plateau pika is considered a keystone species and also considered a pest because of the degradation it causes to crops. This causes a competition in foraging with the livestock of farmers such as yaks, sheep, and horses, which in turn affects their livelihood. Conservation efforts for the Plateau pika have focused on a number of strategies. One approach has been to raise awareness among local communities about the important role that the pika plays in the ecosystem and to promote more sustainable farming practices that do not rely on exterminating the animals. This can involve providing alternative methods for protecting crops, such as using fencing or other physical barriers.
Another strategy has been to establish protected areas where the pika and other wildlife can thrive without interference from human activities. For example, the Sanjiangyuan National Nature Reserve in China, which encompasses much of the Tibetan Plateau, has been designated as a protected area for the pika and other endangered species.
Finally, some researchers have been studying the biology and behavior of the Plateau pika in order to better understand the species and its role in the ecosystem. This information can then be used to inform conservation efforts and management strategies.
Overall, conservation efforts for the Plateau pika are aimed at ensuring the long-term survival of the species while also promoting sustainable development in the region. By working to protect this important component of the high-altitude ecosystem, conservationists hope to maintain the ecological integrity and biodiversity of the region for generations to come.
