AI Article Synopsis
- - The study explores the historical background of domestic yak and cattle on the Tibetan Plateau, focusing on their significance for herders living at high altitudes and the limited previous knowledge on their history.
- - Researchers analyzed 193 animal remains and sequenced genomes from recent excavations, revealing a greater presence of cattle compared to yak and evidence of hybridization between the two species around 2500 years ago.
- - Findings suggest that a diverse reliance on these animals has enhanced herder adaptability to high-altitude conditions, with ancient livestock being closely related to modern species, highlighting a long-standing tradition of yak and cattle husbandry in the region.
Article Abstract
Domestic yak, cattle, and their hybrids are fundamental to herder survival at high altitudes on the Tibetan Plateau. However, little is known about their history. remains are uncommon in this region, and ancient domestic yak have not been securely identified. To identify taxa and investigate their initial management, we conducted zooarchaeological analyses of 193 specimens and sequenced five nuclear genomes from recently excavated assemblages at Bangga. Morphological data indicated that more cattle than yak were present. Ancient mitochondrial DNA and nuclear genome sequences identified taurine cattle and provided evidence for domestic yak and yak-cattle hybridization ~2500 years ago. Reliance on diverse species and their hybrid has increased cattle adaptation and herder resilience to plateau conditions. Ancient cattle and yak at Bangga were closely related to contemporary livestock, indicating early herder legacies and the continuity of cattle and yak husbandry on the Tibetan Plateau.

Ardeids are wild birds well adapted to urban and periurban environments. However, the association of wildlife with humans and livestock increases the chances of transmission of microorganisms between wild animals, domestic animals and humans. The present study aimed to investigate the occurrence of Salmonella spp.

The infestation of ruminants by fly larvae of the Oestridae family can lead to nasopharyngeal or subcutaneous myiasis, which can harm animal welfare and productivity on sheep and cattle farms. The infestation of wild ruminants allows them to serve as reservoirs for subsequent transfer to domestic animals. The fly species most commonly responsible for myiasis have been well studied in many parts of the world, but less so in southeastern Europe.

Ticks are medically important vectors of pathogens, many of which are zoonotic or impact domestic animal and/or wildlife health. Climate change, landuse modifications, and increasing interactions between domestic animals, wildlife, and humans have resulted in changes in tick-host dynamics and the emergence of novel pathogens worldwide. Therefore, describing the host and geographic ranges of vector species is essential in assessing disease risk, especially in understudied areas, and should be conducted in a One Health context.

Fertility rates are declining in livestock such as cattle, and more than one in five Japanese couples have undergone infertility treatment or are currently infertile. Improving the fertilization rates of domesticated animals is imperative for improving their productivity and maintaining valuable lineages. In this study, the effects of rutin and quercetin on fertility and pregnancy rates were investigated by incorporating these compounds into the preculture medium for fertilization (IVF) or administering them orally to mice.

Culicoides biting midges (Diptera: Ceratopogonidae) have been reported as potential vectors for haemoparasites. Information about host-vector-parasite specificity is required to confirm their status. Here, molecular detection of haemosporidians, Leishmania, trypanosomatids, and filarial nematodes in biting midges was conducted to understand their potential role as vectors, and their host preference was determined.
