The objective of this study was to evaluate the effects of bacterial and chemical additives on the number of lactic acid bacteria (LAB) and on fermentation indicators in whole maize silage at 1, 3, 5,...
Data on 111 environmental weed eradication programs carried out by the New Zealand Department of Conservation (DOC) have been collected and summarized. A total of 21 programs were discontinued, and 90...
《渔业科学进展》(Progress in Fishery Sciences)(双月刊)是由中国水产科学研究院黄海水产研究所和中国水产学会主办、国内外公开发行的学术期刊。1980年创刊,原刊名为《海洋水产研究》,2009年更名为《渔业科学进展》,为中国水产领域最早、最有影响力的学术刊物之一,已经成为我国渔业水产科学领域学术交流的重要平台。《渔业科学进展》现为中文核心期刊、中国科技核心期刊、中国水产核...
A good functional status of cryopreserved boar spermatozoa is very important for successful fertilization of porcine oocytes and in vitro embryo production. The purpose of the study was to evaluate th...
The changes in water quality caused by grassing of arable land followed by the reduction in the use of fertilisers after 1989 are demonstrated on an example of two tile-drained subcatchments in spring...
In 2002–2003, we conducted a detailed inventory of bark stripping damage in Forest District (FD) Mořkov (Forest Enterprise Frydek-Místek) and in Forest Range (FR) Proklest (Training Forest Enterp...
China was one of the earliest countries to set up a system to continuously inventory natural forest resources. From the beginning of the 1970s until today, seven forest resource inventories have been ...
Cryptosporidium, the protozoan parasite, has several transmission routes,including anthroponotic and zoonotic transmission, as well as the foodborne way, but mainly by water.
Probing undiscovered neuropeptides that play important roles in the regulation of pituitary function is essential for the progress of avian endocrinology and neuroendocrinology. Neuropeptide control o...
In this study, the progress of growth stage and change in freezing hardiness of tea [Camellia sinensis (L.) O. Kuntze] bud were examined from January to April in relation to air temperature for 10 yea...
This paper describes the development of micro-financial activities in less developed countries in the world. The history of this development is divided into four periods with their short characteristi...
The mountain pine beetle epidemic is changing British Columbia forests and watersheds at the landscape scale. Watersheds with dead-pine-leading stands in the Vanderhoof Forest District of central Brit...
摘要本文就目前国内外林木连锁遗传图谱领域的研究进展进行了综述,指出了该领域研究中存在的主要问题,即一方面是作图个体的数量有限,另一方面是采用的标记以随机标记为主,导致了建成的图谱以及利用图谱获得的数量性状基因位点(QTLs)信息具有杂交组合特异性,造成了QTLs的可信度和在林木遗传改良以及标记辅助选择中的实用性降低等现象。针对存在的问题,讨论了根据林木生物学特点选择合适遗传标记的意义,指出进行林木...
摘要肌肉生长和品质是目前猪肉分子遗传基础研究的两个重要内容。通过候选基因法和基因组扫描法已鉴定出包括氟烷基因和酸肉基因在内的多个影响猪肉生长和品质的功能基因及若干QTLs。猪肌肉和脂肪相关基因转录谱的研究亦初步展开。但是,这些研究在一定程度上均表现出某些不足。分子数量遗传学的研究过分强调单个基因的作用而忽略了多基因的系统表达模式,转录谱的研究则存在实验技术单一以及将肌肉和脂肪受控基因人为分离进行研...
