利木赞牛杂交改良对草原红牛肉质的影响

将纯种草原红牛和含1/2利木赞血缘的改良草原红牛各16头在相同营养水平和饲养条件下进行10个月的集中舍饲育肥，研究了2组牛生长速度、产肉率及眼肌面积、大理石花纹和嫩度等肉质水平。结果显示, 改良牛的体高、体长、胸围、体质量、增重、屠宰率和净肉率等极显著或显著地高于草原红牛（P<0.01或P<0.05），改良牛的眼肌面积比草原红牛增8.39%，大理石花纹等级和嫩度剪切力值也略大于草原红牛，但差异均不显著(P>0.05)。试验结果表明，利木赞牛对草原红牛的肉用性能改良效果显著，且对草原红牛的肉质没有明显影响,草原红牛保持了其原有肉质好的品种特性。

小草在中国古代诗词中的作用与影响

中国古代诗词与诗歌中有关小草的描述与表达,历史悠久,内容丰富多彩。草在诗词中的作用突出,影响甚广,其中以草写景、以草抒情、借草比喻的作品数最多。很多诗人还常常借草抒发悲欢离合的情绪,反映其对亲人、恋人、朋友和故乡的思念;还有不少诗人用草来表达其人生观、世界观、价值观和情爱观。小草在古代诗词与诗歌中的作用与影响也在很大程度上反映出中国古代的草文化。     

A spotlight on snow leopard conservation in China

China holds the greatest proportion of the snow leopard's (Panthera uncia) global range and is central to their conservation. The country is also undergoing unprecedented economic growth, which increases both the threats to the snow leopard and the opportunities for its conservation. In this paper we aim to review published literature (from 1950 to 2014) in English and Mandarin on snow leopard ecology and conservation in China in order to identify thematic and geographic research gaps and propose research priorities. We first retrieved all published items that considered snow leopards in China (n = 106). We extracted from these papers 274 reports of snow leopard presence in China. We then reviewed a subset of papers (n = 33) of this literature, which specifically focused on snow leopard ecology and conservation within China. We introduced a thematic framework that allows a structured and comprehensive assessment of findings. This framework recognizes 4 critical and interrelated topics underpinning snow leopard ecology and conservation: habitat (distribution and protected area coverage); prey (distribution and abundance, predator–prey relationships); human interactions (hunting and trade, livestock interactions and conflicts); and the underlying policy context. Significant gains in knowledge as well as research gaps and priorities are discussed with reference to our framework. The modest quantity and limited scope of published research on the snow leopard in China calls for a continued and intensified effort to inform and support national conservation policies.     

雌激素和孕酮对犬子宫内膜基质细胞增殖和孕酮受体表达的影响

本试验应用不同消化分离途径获取犬子宫内膜基质细胞,调节培养液中雌激素(E₂)和孕酮(P₄)的浓度,采用MTT法测定E₂和P₄浓度水平对犬子宫内膜基质细胞体外增殖的影响,利用细胞免疫组织化学法鉴定细胞并测定细胞孕酮受体(PR)表达与激素浓度水平的相关性。结果表明,E₂浓度变化(15、30、100 pg/mL)对犬子宫内膜基质细胞的增殖和PR的表达均没有显著的调节作用(P>0.05);P₄(15、30 ng/mL)对犬子宫内膜基质细胞的增殖有显著促进作用(P<0.05),P₄(3、15、30 ng/mL)对犬子宫内膜基质细胞PR的表达具有显著的抑制作用(P<0.05),其影响程度与浓度和作用时间关系密切。

我国猕猴桃细菌性溃疡病研究分析及防控

【目的】为了明确猕猴桃细菌性溃疡病的研究动态和进展,为该病的研究和防治提供参考。【方法】对1988-2015年期间中国知网中国期刊全文数据库上的猕猴桃细菌性溃疡病文献进行了统计分析。【结果】结果表明：我国猕猴桃细菌性溃疡病逐年加重,各猕猴桃产区发生不均衡;从文献研究内容上看,对猕猴桃细菌性溃疡病的防治和药剂筛选试验等内容较多,对病害的基础性研究以及规律、预测预报等方面研究较少。【结论】本文在详细分析文献的基础上提出了猕猴桃细菌性溃疡病的防控建议。     

要正确对待西部种草

西部种草需要正确对待几个问题：良种不是绝对的，与环境协调发展的就是好草种；种草的效益不是单方面的，不是追求单方面的效益；人工草地是现代农业的必要组分，同时不要忽视天然草原；种草不要忽视灌木，清除灌木要慎重；种草要有必要农业投入，应该用好地种草；要以发展动物生产和饲料工业为重点，完善草地农业系统；管理是草业的命脉，应尽早达到草业生产数字化。     

A short note on the horizontal and vertical movements of a whale shark, Rhincodon typus, tracked by satellite telemetry in the South China Sea

Whale sharks, a global migratory species, are often reported entangled in fishing nets in coastal areas of China. The effectiveness of conservation measures has been constrained by very limited knowledge on their movements and preferred habitats in the coastal areas of China. For the first time, we tracked the movements of 2 whale sharks by satellite telemetry in Mainland China. The tracking results of 1 whale shark revealed that it travelled in the South China Sea in a south-eastern direction, parallel to the eastern coast of Vietnam. Total distance travelled was 1018 km, in approximately 74 days, with a mean speed of 14 km per day. It appeared to head towards the cool upwelling zones in southern Vietnam at the time of the tag's detachment. In our study, it was observed that this whale shark was a surface dweller and spent approximately 45% of its time above 10 m water depth and 90% of its time above 50 m depth. It also tended to stay in water temperatures between 27 and 30 °C, and was rarely recorded in water below 20 °C. This preliminary study indicates the importance of shallow waters as the foraging habitat for whale sharks, and has implications for their management and conservation.
