Abstract

Abstract We studied female Gopherus morafkai reproduction for 10 yr to evaluate reproductive variation and environmental factors that influenced reproduction. In contrast to vitellogenesis in other Gopherus, substantial follicle growth occurred during the spring after emergence from hibernation. Vitellogenesis and egg production varied considerably among individuals. The smallest egg-producing female had a carapace length of 220 mm, and no female produced more than one clutch per year. Compared to small females, large females were more likely to reproduce in a given year and produced larger eggs, but body size did not affect clutch size. Good maternal body condition contributed to follicle growth in winter, larger clutches, and larger eggs in a clutch. Females that emerged from hibernation earlier were more likely to produce eggs. Early-emerging females also produced larger eggs than did females that emerged later. These reproductive traits contribute to a life history that resembles an income breeder compared to the more capital-breeding strategy of the closely related Mojave Desert Tortoise (Gopherus agassizii). These life history differences might convey different reproductive and population consequences of climate change.

雌性索诺兰沙漠龟(Gopherus morafkai)的繁殖生态学和生活史
摘要我们对雌性莫拉夫凯山羊的繁殖进行了10年的研究,以评估繁殖变异和影响繁殖的环境因素。与其他Gopherus的卵黄发生相反,卵泡在冬眠后的春季大量生长。不同个体的卵黄生成和卵子产量差异很大。最小的产卵雌性的甲壳长度为220毫米,没有一只雌性每年产卵超过一窝。与体型较小的雌性相比,体型较大的雌性更有可能在特定年份繁殖,产下更大的卵子,但体型并不影响离合器的大小。良好的母体身体状况有助于冬季卵泡的生长、更大的卵窝和更大的卵子。较早从冬眠中苏醒的雌性更有可能产卵。早期出现的雌性也比后来出现的雌性产下更大的卵子。与亲缘关系密切的莫哈韦沙漠龟(Gopherus agassizii)更具资本的繁殖策略相比,这些繁殖特征有助于形成一种类似于收入饲养员的生活史。这些生活史的差异可能传达出气候变化对生殖和人口的不同影响。
