金头龟学名黄缘盒龟,也有人称它为黄缘闭壳龟、断板龟、夹蛇龟、黄板龟。在我国分布较广,主要分布在福建、浙江、江苏、安徽、湖南、湖北、河南以及台湾等地。金头龟背部隆起很明显,像半个皮球,十分有趣。金头龟虽然也会游泳,但不太喜欢下水,属半水栖龟类,生活于林子边缘或有少量小树的草山上,以小虫为食,生长较慢。 相似文献

1983年第4期《野生动物》杂志刊登一篇题为《救救黄缘闭壳龟》的文章。该文说,由于人们的滥捕,致使大别山区该龟类的数量锐减。呼吁把黄缘闭壳龟列为保护动物,以杜绝灭。闭壳龟(Cuora)是龟科(Emydidae)的一现生属,生活于东亚和东南亚一带,别处未见,可谓是“亚洲的特产”。现知6个现生种,即黄缘闭壳龟(C.flavomarginata)、三线闭壳龟(C.trifasciata)、海南闭壳龟(C.hainanensis)、云南闭壳龟(C.yunn-anensis)、安布闭壳龟(C.amboinensis)和黄额闭壳龟(C.galbinifrons)。我国产前 相似文献

对黄缘闭壳龟的产卵及人工孵化进行试验,结果显示,黄缘闭壳龟每只雌龟年产卵量为3.41枚,分1~3次产出,龟卵的受精率为73.71%,龟卵的孵化率为88.30%。产卵量、受精率及孵化率是人工孵化的关键技术指标,有较大的提升空间。 相似文献

A healthy adult, intact female keeled box turtle (Cuora mouhotii) was found to have a marked heterophilic leukocytosis using normal hematologic parameters established for the eastern box turtle (Terrapene carolina carolina), a related chelonian species. This animal was monitored with serial complete blood counts (CBCs) over the next 15 years despite remaining asymptomatic for an infectious condition. Retrospective CBC data were compiled from 38 presumably healthy keeled box turtles to establish hematologic values for comparison in this species. Using this species-specific data, over the 15-year period, the female keeled box turtle had two times where the white blood cell (WBC) count was greater than 2 standard deviations (SD) above the mean, six times where the WBC count was greater than 1 SD above the mean, six times where the PCV was greater than 2 SD above the mean, and eight times where the PCV was greater than 1 SD above the mean. Infection and inflammation are the most common causes of leukocytosis in reptiles; however, given the clinical presentation of this patient, it was postulated that these clinicopathologic changes could be secondary to a stress response. Establishing reference intervals and understanding how stress impacts CBC parameters are important for evaluating the health status of keeled box turtles kept in captivity and for assessing the effects of environmental changes on the health status of wild populations of this endangered chelonian species. 相似文献

安徽省两栖爬行动物物种分布特征 总被引：2，自引：0，他引：2
基于现有的安徽省两栖爬行动物分布资料,系统整理物种分布数据,建立两栖爬行动物地理分布原始数据库。运用GIS技术,以县级行政区为地理单元,分析物种丰富度格局,通过多元统计分析,研究物种多样性的区域分异。结果表明,皖南山地丘陵和大别山山地丘陵地带物种丰富度最高：淮北平原、江淮丘陵的物种丰富度相对较低;但淮北平原和江淮丘陵的部分山地丘陵物种丰富度相对较高。根据各县的分布型物种数量分布,当聚为2组（Jaccard系数大于7.612）时,安徽省物种分布型区域分异基本上呈现山区系组（皖南山区和大别山区）和丘陵平原组特征,当聚为3组（Jaccard系数小于5.075）时,丘陵平原组又可分为江淮丘陵平原组和淮北平原组;当划分为4组（Jaccard系数等于2.537）,山地区系组又可以分为皖南山区组和大别山区组。 相似文献

野生金头闭壳龟的资源现状调查 总被引：3，自引：1，他引：3
笔者于2001-2004年对金头闭壳龟(Cuoraaurocapitata)的野生种群的分布、数量及相关生态学进行了专项调查。结果表明,金头闭壳龟目前仅分布于青弋江源头和上游即北纬30°-30°52′的少数支流中,具体为安徽省泾县的古坝、蔡村和孤峰三地的山涧溪流以及黟县红星乡的清溪河流域。野外种群数量十分稀少,目前已不足400只。金头闭壳龟主要栖息在水质清澈、两侧植被茂密或一侧山脚多石缝的山涧溪流中。经对曾经发现过金头闭壳龟典型地带的各种生态指标的测量表明,泾县古坝乡沈村上沈村段的古坝河段的以及蔡村乡的东园至爱民段的丁溪河段,相比而言仍不失为金头闭壳龟较为理想的栖息地。 相似文献

ObjectiveTo evaluate latency and duration of a brachial plexus block technique in eastern box turtles performed with 2% lidocaine at three dose rates.Study designProspective, randomized, blinded crossover study.AnimalsAdult eastern box turtles, two for drug dose evaluation and a group of six (three male, three female) weighing 432 ± 40 g (mean ± standard deviation) for the main study.MethodsAnimals were randomly assigned to four brachial plexus blocks with lidocaine at 5, 10 and 20 mg kg–1 or 0.9% saline (treatments LID5, LID10, LID20 and CON, respectively), separated by 1 week. Treatment side was randomized and blocks were performed unilaterally. Baseline observations of mentation, heart rate (HR), respiratory rate (fR), skin temperature and limb response to manipulation or toe pinch were evaluated. Assessments were made every 10 minutes until 1 hour of normal sensory and motor function to the treated thoracic limb, or for a total of 2 hours if no block was evident.ResultsMotor and sensory blockade was achieved in treatments LID10 and LID20 in one turtle, with a latency of 10 minutes and duration of 50 minutes for both doses. Raising of the ipsilateral lower palpebra occurred with both blocks. Turtles administered lidocaine experienced higher HR compared with CON, and HR decreased over time for all individuals. Mentation and fR were not changed with any lidocaine dose.ConclusionsThe technique was unreliable in producing brachial plexus motor and sensory blockade at the lidocaine doses evaluated in this study. HR was higher in lidocaine-administered turtles but remained within normal limits for the species. No change in mentation or fR was observed among treatments.Clinical relevanceGeneral anesthesia with systemic analgesia is recommended for surgical procedures involving the chelonian thoracic limb. Further studies are needed to optimize a brachial plexus block in this species. 相似文献

In this study, 10% of all registered fishermen in the coastal towns of Navachiste in Sinaloa, in northwestern Mexico, answered a survey designed to collect data on their perceptions of the following topics: the impact of turtle meat consumption; human health; bycatch; illegal turtle fishing; the illegal sea turtle market; the local economy; pollution; environmental education; the success of protective legislation; and sea turtle‐based ecotourism. Perceptions were analyzed using the fuzzy logic method through classification into 5 fuzzy membership sets: VL, very low; L, low; M, moderate; H, high; VH, very high. The 9 topics generated decision areas upon applying fuzzy inference that revealed the membership level of the answers in each fuzzy set. The economic potential of sea turtle‐based ecotourism and the economic profitability of the illegal turtle meat market were perceived as VL. Conservation legislation was perceived as H, although inefficiently applied due to corruption. Ecotourism and impacts on sea turtles were perceived as VL, because they were deemed unprofitable activities at the individual and community levels. Environmental education was perceived as L, because it centers on nesting, hatching and releasing turtles and is directed at elementary and middle‐school students. While fishers perceive a serious negative impact of fishing activities on sea turtles in the San Ignacio‐Navachiste‐Macapule area, they do not see themselves individually as part of the problem. Achieving sea turtle conservation in this region requires: suitable ecotourism infrastructure, government investments in promotion, and studies to estimate the minimum number of tourists needed to assure profitability. 相似文献

Objective The Leatherback sea turtle is the largest extant reptile and the sole member of the family Dermochelyidae. Here, the eye of this critically endangered marine turtle was investigated to determine the anatomy, optics, and optical sensitivity. Animals studied Three Leatherback sea turtles, Dermochelys coriacea. Results The eye is small in proportion to body size of the adult compared to other vertebrates, with prominence of the retractor bulbi and pyramidalis muscles. The nictitans shows extensive folding of the bulbar conjunctiva as an apparent mechanism to increase the surface area for mucus secretion. The intraocular anatomy is consistent with an eye adapted to aquatic vision with minimal curvature of the cornea, a near‐spherical lens, deep ciliary cleft and highly vascularized ciliary body. The optical sensitivity, a measure of the sensitivity to light of a given optical system, is higher than in other marine turtles studied but lower than those found in teleost fish that share a habitat with the Leatherback sea turtle. Conclusions The Leatherback sea turtle shows ocular features that are characteristic of Chelonians with similarities to aquatic mammals. The calculated optical sensitivity suggests that compared to pelagic fishes, for instance, the Leatherback sea turtle eye is not particularly well adapted for vision in dim light even though this species is known to venture into deep, dark waters, and might feed at night. 相似文献
