摘要

家园范围(Home range, HRs)是动物与其环境相互作用的区域,是动物生态学的一个基本方面。人力资源的规模和位置通常反映了与各种社会、生物和非生物因素相关的成本和收益。然而,对于这些因素如何影响种内人力资源大小或保真度(个体随时间保持相同人力资源位置的倾向)的变化,或者这些特征的变化是否来自个体之间或它们所占据的位置之间的一致差异,我们知之甚少。为了解决这一知识差距,我们使用了一种长寿蜥蜴的广泛gps跟踪数据集,其中包括多年来对多个个体的重复观察。我们测试了三类预测因素——(1)蜥蜴特征(性别、攻击性和寄生蜱虫数量),(2)环境特征(降水、食物和避难所质量),以及(3)社会条件(同种重叠和邻居数量)——如何影响HR大小和保真度。我们发现个体在年度人力资源的大小和保真度上存在一致的差异(重复性分别为0.58和0.33),并且所有三类预测因子都影响人力资源的大小和保真度。例如,在食物丰富的地区,hr更小,男性的hr比女性大。此外,更具攻击性的蜥蜴往往有更大的hr。同种重叠和与蜥蜴互动的个体数量(社会网络程度)对人力资源大小有交互影响,与邻居重叠越多的个体的人力资源越大,这种影响对与更多邻居互动的个体尤为强烈。人力资源保真度随着时间的推移而下降(人力资源位置每年都在变化),但个人在这种变化速度上是一致的。尽管位置漂移,但HR大小是一致的,这表明蜥蜴的HR反映了个体特征(例如,个体之间的栖息地选择标准不同),而不是简单的地点之间的异质性。总体而言,这些发现表明:(1)空间利用具有强烈的、长期的个体内一致性和个体间差异;(2)个体特征、社会条件和环境特征对动物hr的综合影响,并对多种生态过程产生影响。

Intrinsic traits, social context, and local environment shape home range size and fidelity of sleepy lizards

Home ranges (HRs), the regions within which animals interact with their environment, constitute a fundamental aspect of their ecology. HR sizes and locations commonly reflect costs and benefits associated with diverse social, biotic, and abiotic factors. Less is known, however, about how these factors affect intraspecific variation in HR size or fidelity (the individual's tendency to maintain the same HR location over time) or whether variation in these features emerge from consistent differences among individuals or among the sites they occupy. To address this knowledge gap, we used an extensive GPS-tracking data set of a long-lived lizard, the sleepy lizard (Tiliqua rugosa), which included repeated observations of multiple individuals across years. We tested how three categories of predictors—(1) lizard characteristics (sex, aggressiveness, and parasitic tick counts), (2) environmental characteristics (precipitation, food, and refuge quality), and (3) social conditions (conspecific overlap and number of neighbors)—affected HR size and fidelity. We found that individuals differed consistently in the size and fidelity of annual HRs (with a repeatability of 0.58 and 0.33, respectively), and that all three categories of predictors affected both HR size and fidelity. For example, HRs were smaller in areas with more food, and males had larger HRs than females. In addition, more aggressive lizards tended to have larger HRs. Conspecific overlap and number of individuals that a lizard interacted with (social network degree) had an interactive effect on HR size where individuals whose HRs overlapped more with neighbors had larger HRs, and this effect was particularly strong for individuals that interacted with more neighbors. HR fidelity declined over time (HR locations drifted from year to year), but individuals differed consistently in this rate of drift. The fact that HR size was consistent despite drifting locations suggests that lizard HRs reflect individual traits (e.g., habitat choice criteria that differ among individuals), rather than simple heterogeneity among sites. Overall, these findings demonstrate (1) both strong, long-term, within-individual consistency and between-individual differences in space use and (2) combined effects of individual traits, social conditions, and environmental characteristics on animal HRs, with implications for diverse ecological processes.

期刊介绍: The vision for Ecological Monographs is that it should be the place for publishing integrative, synthetic papers that elaborate new directions for the field of ecology. Original Research Papers published in Ecological Monographs will continue to document complex observational, experimental, or theoretical studies that by their very integrated nature defy dissolution into shorter publications focused on a single topic or message. Reviews will be comprehensive and synthetic papers that establish new benchmarks in the field, define directions for future research, contribute to fundamental understanding of ecological principles, and derive principles for ecological management in its broadest sense (including, but not limited to: conservation, mitigation, restoration, and pro-active protection of the environment). Reviews should reflect the full development of a topic and encompass relevant natural history, observational and experimental data, analyses, models, and theory. Reviews published in Ecological Monographs should further blur the boundaries between “basic” and “applied” ecology. Concepts and Synthesis papers will conceptually advance the field of ecology. These papers are expected to go well beyond works being reviewed and include discussion of new directions, new syntheses, and resolutions of old questions. In this world of rapid scientific advancement and never-ending environmental change, there needs to be room for the thoughtful integration of scientific ideas, data, and concepts that feeds the mind and guides the development of the maturing science of ecology. Ecological Monographs provides that room, with an expansive view to a sustainable future.
