摘要

摘要反社会幼仔孵化后立即离开巢穴,在快速发育期间作为一个群体移动和觅食。生长和身体状况与生存相关;随着体型的增大,幼崽能够更好地调节体温,随着行动能力的增强,它们也能更好地逃离捕食者。环境条件可以影响发展并最终影响生存。我们评估了天气、覆盖类型和影响北方山猫幼鱼身体状况的时间因素。2017年和2018年,我们在密苏里州西南部的五个保护区捕获了来自33只>16日龄的幼崽的216只。孵化日期为5月26日至9月19日。身体状况被测量为捕获时幼年跗骨长度和体重的线性回归的残差。我们发现,在繁殖季节早期以及在前2年内被烧毁和放牧的原生草原上,身体状况有所改善有一定的支持。然而,代表这些影响的模型与零模型有相似的支持(即ΔWAIC<2),表明支持较弱。对这些影响的有限支持可能是由于数据有限或我们的竞争模型集中未考虑的其他环境因素的影响。我们的顶级模型支持孵化日期较晚和农业作物覆盖对幼崽身体状况的负面影响。早期繁殖季节是山猫成功生产力的重要时期,通过轮作和放牧管理的原生草原可以创造更高质量的育婴栖息地,以改善幼崽的身体状况。

Early Hatch and Managed Native Grasslands Minorly Improve Bobwhite Juvenile Body Condition
Abstract. Precocial young leave their nest immediately after hatch to move and forage as a group during a rapid period of development. Growth and body condition are correlated with survival; young are better able to thermoregulate as they become larger, and they are better able to escape predators as they become more mobile. Environmental conditions can influence development and ultimately survival. We evaluated weather, cover type, and temporal factors affecting northern bobwhite juvenile body condition. We captured 216 individuals from 33 broods >16 d old on five conservation areas in southwest Missouri in 2017 and 2018. Brood hatch dates ranged from 26 May through 19 September. Body condition was measured as the residuals from a linear regression of juvenile tarsus length and body mass on capture. We found some support for improved body condition earlier in the breeding season and in native grasslands that were burned and grazed within the previous 2 y. However, models representing these effects had similar support to the null model (i.e., ΔWAIC<2), indicating weak support. Limited support for these effects may have been due to limited data or the influence of other environmental factors not considered in our competing model set. Our top model supported negative effects of later hatching date and agricultural crop cover on juvenile body condition. The early breeding season is an important period for successful bobwhite productivity, and native grasslands managed with rotational fire and grazing may create higher quality brood rearing habitat for improved juvenile body condition.

期刊介绍: The American Midland Naturalist has been published for 90 years by the University of Notre Dame. The connotations of Midland and Naturalist have broadened and its geographic coverage now includes North America with occasional articles from other continents. The old image of naturalist has changed and the journal publishes what Charles Elton aptly termed "scientific natural history" including field and experimental biology. Its significance and breadth of coverage are evident in that the American Midland Naturalist is among the most frequently cited journals in publications on ecology, mammalogy, herpetology, ornithology, ichthyology, parasitology, aquatic and invertebrate biology and other biological disciplines.
