Conservation Biology, Volume 33, Issue 5, Page 1084-1093, October 2019., 2019 Abstract The IUCN (International Union for Conservation of Nature) Red List categories and criteria are the most widely used framework for assessing the relative extinction risk of species. The criteria are based on quantitative thresholds relating to the size, trends, and structure of species’ distributions and populations.

International Journal of Urban and Regional Research, Volume 50, Issue 1, Page 191-220, January 2026.Abstract Henry George advocated for capturing land value increases for public ends. The active approach of public authorities organizing and financing land development can help capture higher land value increases, as Hartman and Spit indicate. However, this approach hardly happens in developing countries, where the coalition of private developers and ...

, 2012 水体富营养化日益严重,水华频繁爆发,如何有效控制水华,治理富营养化水体是目前水环境领域的研究热点和前沿。目前湖泊藻类控制技术主要有:物理方法、化学法、生物法,但是这些方法都有其固有的缺点。利用植物化感作用抑制有害藻类生长具有廉价、生态安全等优点近年来备受关注。化感作用就是生物体产生的生物活性物质即化感物质在生物体之间传递信息并导致生物体相互作用。归纳了国内外不同生活型水生植物化感作用研究的主要成果(包括已报道的抑藻水生植物种类、已从水生植物体内和种植水中分离鉴定得到的化感物质 ...

Integrative Conservation, Volume 4, Issue 3, Page 277-286, September 2025.This study provides an innovation to address the challenge in accessibility to samples and genetic markers in Snow leopard conservation genetic studies. We performed next‐generation sequencing (NGS) on 19 fecal samples obtained from the eastern Qinghai‐Tibet Plateau, and successfully assembled 17 complete mitogenome sequences (~16,720 bp) and ...

, 2012 从广东省以及海南省等地区养殖的患病罗非鱼体内分离、收集到多株致病菌,经生化分析和分子生物学鉴定,均为无乳链球菌。对这些菌株分别进行了耐药谱测定、分子分型试验以及分子血清型分析。药敏试验结果表明,2007—2010年分离到的无乳链球菌耐药谱基本相似;多位点可变数目串联重复序列分析(MLVA)试验中,选择5个高变异指数的可变数目重复位点(VNTR)进行分子分型,结果表明,所有鱼源无乳链球菌菌株为同一MLVA型,而作为对照的牛源无乳链球菌则明显不同;为了对这些菌株进一步分型 ...

Veterinary Dermatology, Volume 36, Issue 4, Page 474-484, August 2025.Background – Sporotrichosis is a chronic, mycotic infection caused by fungi of the genus Sporothrix. Zoonotic sporotrichosis occurs mainly through S. brasiliensis transmission, resulting from the organism's traumatic introduction via scratches or bites, or contact with exudate from contaminated cats.

Study on establisment of chicken embryo RNAi technology with infective feature of RCAS and Vezf1 function in chicken vascular development. [PDF]
, 2012 早期初级血管网络的形成，始于胚胎中胚层形成过程中其部分细胞分化为血管内皮前体细胞。血管内皮前体细胞再进一步向血管内皮细胞分化并形成初级毛细血管网，血管内皮细胞与其周围细胞进一步相互作用，逐步进行对初级血管的改建和生成新的血管，最终完成血管系统的发育。因此，血管内皮细胞是血管生成的中心细胞。为研究胚胎血管内皮细胞分化机制，先前我们从发育至三体节的鸡内皮前体细胞（VEGFR2+）相对特异表达基因的克隆中，发现了鸡的Vezf1(cVezf1)基因。该基因与在小鼠中发现的Vezf1基因高度同源 ...

Veterinary Dermatology, Volume 36, Issue 3, Page 302-313, June 2025.Background – Malassezia pachydermatis (MP) is implicated in severe dermatitis and otitis externa (OE) of companion animals and recently gained attention for its increasing resistance to azole compounds. For this reason, developing novel therapeutic strategies is of great interest. In a previous work, we used reference yeast isolates to evaluate several
