Abstract

This paper presents novel baseline health parameters on the Española lava lizard (Microlophus delanonis). Blood samples and morphological measurements were taken on 51 lizards (21 males, 30 females) captured from three locations on the island of Española. Morphologic parameters measured included body weight, snout-vent length, and temperature. Blood samples were analyzed approximately eight hours after collection using a portable blood analyzer (i-STAT) which measured hemoglobin, total CO2, glucose, lactate, sodium, potassium, and ionized calcium. Hematologic characterization data were obtained using standard laboratory techniques. There were significant differences found in snout-vent length, weight, heart rate, respiratory rate, total CO2, and heterophil percentage between males and females. The data presented here can be used to monitor the health of this population of lava lizards as well as help to understand the health of a related species, the San Cristóbal lava lizard (Microlophus bivittatus), which faces different evolutionary pressures including the presence of humans and feral cats. This study continues to widen our understanding of the Microlophus genus; however, further research should be done to characterize the remaining species that inhabit the islands in the Galápagos archipelago.
Española熔岩蜥蜴的血液学和生物化学研究
本文提出了Española熔岩蜥蜴(Microlophus delanonis)新的基线健康参数。对在Española岛上三个地点捕获的51只蜥蜴(21只雄性,30只雌性)进行了血液样本和形态学测量。测量的形态学参数包括体重、口鼻长度和体温。血液样本在收集后大约8小时使用便携式血液分析仪(i-STAT)进行分析,测量血红蛋白、总二氧化碳、葡萄糖、乳酸、钠、钾和电离钙。使用标准实验室技术获得血液学特征数据。雄性和雌性在鼻口长度、体重、心率、呼吸频率、总CO2和异性恋率方面存在显著差异。这里提供的数据可以用来监测这个熔岩蜥蜴种群的健康状况,也有助于了解一个相关物种,San Cristóbal熔岩蜥蜴(Microlophus bivittatus)的健康状况,它面临着不同的进化压力,包括人类和野猫的存在。这项研究继续扩大了我们对小龙虾属的认识;然而,应该进行进一步的研究,以确定居住在Galápagos群岛岛屿上的剩余物种的特征。
