红喉歌鸲黑龙江种群遗传多样性和遗传结构分析

野生动物学报
为揭示红喉歌鸲（Calliope calliope）黑龙江种群的遗传多样性和遗传结构，测定了85只个体细胞色素b基因序列，结合下载的135条同源序列进行综合分析。结果显示：黑龙江种群包含50个细胞色素b基因单倍型（1 143 bp），其中42个为独特的新单倍型，8个为共享单倍型。黑龙江种群具有较高的单倍型多样性（h = 0.934 0 ± 0.021 0），但核苷酸多样性较低（π = 0.003 0 ± 0.000 3），且二者均低于西伯利亚、远东岛屿及沿海种群。对此可能的解释是该种群过去经历了瓶颈事件，

Development of a Four‐Language Questionnaire to Investigate Environmental Risk Factors for the Development of Canine Atopic Dermatitis and to Monitor Disease Course and Progression

Veterinary Dermatology, Volume 37, Issue 1, Page 34-44, February 2026.
Background: The chronic and multifactorial character of canine atopic dermatitis (cAD) often leads to poor disease control and treatment dissatisfaction. Environmental factors are likely to contribute to the disease development and may play a more important role than assumed previously.
