Non-governmental Organizations and Government Agencies Lead in Cultivating Positive Sea Turtle Conservation Attitudes

Considerable research has been conducted analyzing how demographic characteristics influence the public’s attitudes toward wildlife; however, less research of this type has been conducted in locations having long-standing species conservation efforts. Questionnaires were completed by residents living adjacent to such a location, the Archie Carr National Wildlife Refuge (ACNWR), to investigate which demographics explained residents’ knowledge of, attitudes toward, willingness to act for, and participation in sea turtle conservation. Residents who had a non-governmental organization (NGO) or government agency as their sea turtle information source had stronger positive attitudes toward sea turtles. Residents who possessed strong positive attitudes were more willing to engage in pro–sea turtle conservation behaviors. Overall, this research demonstrated that ACNWR residents’ source of sea turtle information being an NGO or government agency played a significant role in increasing residents’ knowledge of, attitudes toward, willingness to volunteer for, and participation in sea turtle conservation.     

中华鳖稚鳖对三种抗生素的耐受力测试报告

采用药浴、口灌及注射的给药方式检测了中华鳖稚鳖对红霉素（ＥＭ）、氯霉素（ＣＰ）和土霉素（ＯＴＣ）的耐受力,结果表明用３种抗生素药物以５０００μｇ／ｍＬ药浴,按体重计用１０００μｇ／ｇ口灌和５００μｇ／ｇ（ＣＰ为２００μｇ／ｇ）注射,中华鳖稚鳖均能耐受,表明中华鳖稚鳖对供试抗生素具有较强的耐受力。

中华鳖腐皮病的病原研究

从具有典型腐皮病症状的中华鳖体中分离到P—1、P—2两株细菌,经人工感染试验对健康鳖均产生了较强的致病力,出现与自然病鳖相同的症状,从而证实这两株菌株是中华鳖腐皮病的病原菌。经对菌体的形态特征、培养特性和生理生化反应进行鉴定,证明致病菌为嗜水气单胞菌。

中华鳖MyD88部分序列克隆及其在组织中的表达差异分析

MyD88(Myeloid differentiation factor 88,MyD88)是多数TLRs(Toll like receptor,TLRs)信号转导过程中的关键接头分子。研究根据MyD88(Myeloid differentiation factor 88,MyD88)TIR结构域(Toll-like/IL-1 receptor domain)保守区设计简并引物,通过PCR扩增,成功地从中华鳖脾脏cDNA中扩增出351bp的目标序列。测序后经结构域和序列比较分析,扩增片段为中华鳖的MyD88 TIR结构域。该序列与大黄鱼、鸡等脊椎动物的MyD88的TIR结构域序列同源性和相似性分别为72.9%～86%和77.6%～83.6%。以热灭活嗜水气单胞菌刺激中华鳖后,经荧光定量PCR检测,在48h内,肝、脾和肾组织中MyD88 mRNA相对表达量均出现不同程度的增加,尤以脾脏中的增幅最为明显,为对照组的6.89倍;中华鳖心脏成纤维样细胞经20ng LPS刺激后1～8h,MyD88表达量有所提高,24h的表达量最高。该研究结果将为开展中华鳖天然免疫奠定良好基础。     

Spatiotemporal patterns of annual sea turtle nesting behaviors along an East Central Florida beach

The Florida coastline from Melbourne Beach to Wabasso Beach is one the most important nesting areas for loggerhead turtles (Caretta caretta) in the Western Hemisphere and for green turtles (Chelonia mydas) in the United States. In this study, we quantified the spatial patterns of numerous loggerhead (N≈400,000) and green turtle (N≈14,000) and less numerous (N≈100) leatherback (Dermochelys coriacea) beach ascents from 1989-1999 in terms of their autocorrelative properties along 40.5 km within this critical reproductive zone. Nesting and non-nesting emergence patterns of loggerhead and green turtles were non-random, favoring the southern half of the study area. Perhaps due to low numbers or differences in nesting behavior, leatherback nest distributions were not significantly different from random. Loggerhead and green turtle nest locations exhibited similar clinal patterns. They were positively autocorrelated at distances less than 10 km and negatively at distances greater than 30 km. These patterns were significantly correlated interannually.
