鸟类,特别是濒危鸟类同工酶的分析,长期以来一直受到组织学样品来源上的限制。因为在分析实验中普遍采用血液和各种新鲜组织为分析材料,这常常要损伤或杀死动物,对濒危鸟类的保护是不利的。本文以生长羽毛的羽髓组织为材料,进行了乳酸脱氢酶(LDH)同工酶的凝胶电泳分析。所得谱带清晰,重复性好,且对鸟体无伤害,是濒危鸟类同工酶分析的理想方法。  相似文献

Two surveys of opinions about wildlife conservation were carried out in Hunan Province, China, before and after the severe acute respiratory syndrome (SARS) epidemic. Hunan is the northern neighbor of Guangdong Province, where the first SARS case was reported. The custom of consuming wild meat was not common in Hunan 30 years ago. However, in recent years, consumption of wildlife such as snakes has spread to northern China. We handed out 1300 questionnaires between 22 February and 10 May 2002, before the SARS epidemic. Survey sites included the provincial capital, major cities, towns, and villages in Hunan. Another 1300 questionnaires were distributed between 10 March and 10 May 2004, after the SARS epidemic. The 2004 survey covered the same sites as the 2002 survey. Questionnaire recovery rates for the 2002 and 2004 surveys were 81.2% and 84.6%, respectively. The valid return rate was 73.0%. Frog, snake, hare, and pheasant were the wild meats most frequently eaten by local people. At the time of the first survey, more than 80% of interviewees claimed to have eaten frogs. That number had reduced to 60% by the time of the second survey. Monkey, Chinese pangolin, and bear paw were the wild meats least frequently eaten. Although palm civet was suspected to be the carrier of SARS, it was interesting to note that, after the SARS epidemic, the proportion of people surveyed who ate palm civets had declined only slightly. The results of the surveys indicate a low level of conservation consciousness; however, after the SARS and bird flu epidemics, there were obvious changes in the conservation consciousness of people in Hunan Province. We recommend some measures that could be taken to change the habits of people who consume wildlife.  相似文献

2018年春、夏季,采用样线法对黄盖湖5种生境类型鸟类群落结构进行调查。记录鸟类15目40科119种25816只,雀形目占51.26%,反嘴鹬(Recurvirostra avosetta)、灰翅浮鸥(Chlidonias hybrida)是优势种,主要居留型留鸟50种。3月鸟类最丰富(87种,9084只),4月鸟类最少(60种,2677只),不同月份间鸟类多样性指数、均匀度指数、优势度指数差异不显著。鸟类群落结构生境间变化明显,养殖塘中鸟类最丰富(77种,9716只),明水面最少(15种,1917只),各生境间的鸟类多样性(χ^24=21.561,P=0.000)、均匀度(χ^24=20.168,P=0.000)、优势度指数(χ^24=21.983,P=0.000)均显著差异,明水面生境中鸟类多样性、均匀度指数最小,而优势度指数最大。鸟类群落结构在养殖塘与湖滩生境间相似性最高(0.692),为中等程度相似;明水面与林地生境间相似性最低(0.046),为极不相似。湖泊湿地鸟类保护不仅要优化生境资源的空间配置,还应该重视养殖塘作为退化湖泊湿地重要替代生境的地位,加强养殖塘生境水位管理和降低人为干扰。  相似文献

鸟击事件是长期以来威胁飞行安全的一个国际性难题,目前,国际民航组织(International civil aviation organisation,ICAO)已经将鸟击灾害列为“A类航空灾难”,鸟击防范领域的研究也逐渐受到人们的重视。香柱菌(Epichloё)侵染宿主禾草后形成的共生体可产生有毒生物碱,将共生体发展为高毒驱鸟草种并应用于机场,可以减少鸟击事件的发生。醉马草(Achnatherum inebrians)自身携带甘肃香柱菌(Epichloё gansuensis)和醉马草香柱菌(Epichloё inebrians),野外自然生长的醉马草均为醉马草内生真菌共生体。本文主要通过对比当前国内机场主要驱鸟方式,提出用含有Epichloё属内生真菌的机场驱鸟草替代现有机场草坪草,可作为一种新型驱鸟方式;回顾了当前国外驱鸟草的应用及优势;分析了内生真菌醉马草作为驱鸟草的潜力和存在问题;并对禾草内生真菌的应用及人工栽培醉马草进行展望。  相似文献

Piñon (Pinus spp.) and juniper (Juniperus spp.) removal is a common management approach to restore sagebrush (Artemisia spp.) vegetation in areas experiencing woodland expansion. Because many management treatments are conducted to benefit sagebrush-obligate birds, we surveyed bird communities to assess treatment effectiveness in establishing sagebrush bird communities at study sites in Utah, Nevada, Idaho, and Oregon. Our analyses included data from 1 or 2 yr prior to prescribed fire or mechanical treatment and 3 to 5 yr posttreatment. We used detrended correspondence analysis to 1) identify primary patterns of bird communities surveyed from 2006 to 2011 at point transects, 2) estimate ecological scale of change needed to achieve treatment objectives from the relative dissimilarity of survey points to the ordination region delineating sagebrush bird communities, and 3) measure changes in pre- and posttreatment bird communities. Birds associated with sagebrush, woodlands, and ecotones were detected on our surveys; increased dissimilarity of survey points to the sagebrush bird community was characterized by a gradient of increased juniper and decreased sagebrush cover. Prescribed fires burned between 30% and 97% of our bird survey points. However, from 6% to 24% cover of piñon-juniper still remained posttreatment on the four treatment plots. We measured only slight changes in bird communities, which responded primarily to current vegetation rather than relative amount of change from pretreatment vegetation structure. Bird communities at survey points located at greater ecological scales from the sagebrush bird community changed least and will require more significant impact to achieve changes. Sagebrush bird communities were established at only two survey points, which were adjacent to a larger sagebrush landscape and following almost complete juniper removal by mechanical treatment. Our results indicate that management treatments that leave residual woodland cover and are not adjacent to extensive sagebrush stands are unlikely to establish sagebrush birds.  相似文献

Since 1996, the emergence of Asian-origin highly pathogenic avian influenza subtype H5N1 has spurred great concern for the global poultry industry. In the United States, there is concern over the potential of a foreign avian disease incursion into the country. Noncommercial poultry operations, such as upland game bird facilities in the United States, may serve as a potential source of avian disease introduction to other bird populations including the commercial poultry industry, backyard flocks, or wildlife. In order to evaluate how to prevent disease transmission from these facilities to other populations, we examined biosecurity practices and bird movement within the upland game bird industry in the United States. Persons that held a current permit to keep, breed, or release upland game birds were surveyed for information on biosecurity practices, flock and release environments, and bird movement parameters. Biosecurity practices vary greatly among permit holders. Many facilities allow for interaction between wild birds and pen-reared birds, and there is regular long-distance movement of live adult birds among facilities. Results suggest that upland game bird facilities should be targeted for biosecurity education and disease surveillance efforts.  相似文献
