野生动物学报, 2005 本文对国内外常用的食草动物食性研究方法进行了分析与比较。常见的研究方法主要包括胃分析法、室内饲喂法、粪便显微组织学分析法、直接观察法和利用法。粪便显微分析法分析结果较为精确,并且易于取样,相比较更适用于我国食草动物的食性研究。胃分析法要求研究者必须杀死动物,利用法精确性较差,而观察法多受研究条件的限制, 因此这3种方法多用于食物组成的定性描述,或是作为其它研究方法的补充。

Updated insights into the molecular pathogenesis of canine atopic dermatitis
Veterinary Dermatology, EarlyView.Abstract Atopic dermatitis (AD) is a common and chronic inflammatory skin disease with frequent relapses. The genomics revolution has greatly contributed and revolutionised our knowledge of human AD; understanding the molecular skin fingerprint of AD and associated pathogenic immune pathways has led to preclinical assessments of several novel ...

Veterinary Dermatology, EarlyView.Background – Itch is a common symptom in skin disorders. While the neural pathways of itch transmission from the skin to the brain are well‐understood in rodents, the same pathways in dogs remain unclear. The knowledge gap hinders the development of effective treatments for canine itch‐related disorders.

People and Nature, Volume 7, Issue 7, Page 1749-1768, July 2025.Abstract Social‐ecological systems (SES) are coupled systems formed by the intricate interactions between humans and nature. Our movement towards sustainable lifestyles requires a robust understanding of these interactions. Achieving a sustainable win‐win situation for both social and ecological systems, therefore, necessitates a sound scientific ...
