Core Insights - The absence of cats in the traditional Chinese zodiac is attributed to the historical context of cat domestication and introduction to China, with significant research revealing that leopard cats cohabited with humans in China for 3,500 years, while modern domestic cats were introduced much later [4][9] - Professor Luo Shujin's research spans over 20 years, focusing on the genomic studies of wild cats, particularly the leopard cat, and its relationship with humans, contributing to a deeper understanding of wildlife conservation and species evolution [4][10] Group 1: Research Findings - A breakthrough study from Peking University indicates that leopard cats have been present in China since the Neolithic era, coexisting with humans for thousands of years before retreating to the wild [4][6] - The research team has identified approximately 3,000 leopard cats in Beijing, marking the first systematic survey of this apex predator in the urban ecosystem [9] - The relative abundance of leopard cats in the northwestern mountainous areas of Beijing reached 11%, significantly higher than other regions in China, indicating a suitable habitat for these animals [8][9] Group 2: Methodology and Techniques - The research employs advanced genomic techniques and machine learning for individual identification of leopard cats, enhancing the efficiency of wildlife studies [8] - The team utilizes infrared cameras for monitoring wildlife, allowing for the collection of extensive data on leopard cat behavior and population dynamics [7][8] - Satellite tracking collars have been used to monitor leopard cat movements across various landscapes, providing insights into their habitat preferences [8][9] Group 3: Conservation Efforts - The findings emphasize the importance of habitat preservation and management to ensure the survival of leopard cats and other wildlife in urban settings [9] - Luo Shujin's work contributes to the broader field of wildlife conservation, advocating for the coexistence of humans and wildlife in urban environments [9][19] - The research highlights the potential for restoring populations of other species, such as the North China leopard, through effective conservation strategies [9][10]

新疆卡拉麦里山有蹄类野生动物自然保护区（以下简称"卡山保护区"）是国内最大的普氏野马保护 基地。众多专家学者四十年如一日，扎根荒漠腹地，从零开始进行科学研究，充分运用先进技术手段， 助力普氏野马种群恢复。同时，新疆加快推进普氏野马种群扩散和扩大放归试验，与甘肃、宁夏、内蒙 古等地进行跨区域合作，合力推进普氏野马保护。目前，我国普氏野马种群数量已突破900匹，占全球 总量的1/3。 科技助力种群恢复 在天山脚下的昭苏湿地公园，成群的马匹在平缓的河水中奔跑。与这些常见的家马相比，普氏野马 喜欢离群索居，在外形和基因上，二者均有区别。 新疆野马繁殖研究中心工程师薛剑楠告诉记者，普氏野马头大颈粗、全身呈土黄色，耳短小而圆， 无长额毛，鬃毛短而直立，背部中央有一条黑褐色脊线。 普氏野马有66条染色体，比家马多出两条。作为地球上唯一现存的野生马种，普氏野马仍保留着 6000万年前的原始基因图谱，被称为"生物基因的活化石"，对生态链修复意义重大。 普氏野马是国家一级保护动物、全球濒危大型野生动物，珍稀程度堪比大熊猫。 普氏野马原产于我国新疆准噶尔盆地和蒙古国干旱荒漠草原地带，由于气候变化、人为干扰、栖息 地碎片化等原因，曾 ...
