From leaves to whole plants: effects of shelter-builders on arthropod communities are stronger in dry seasons

Leaf shelters function as microclimatic refuges, reducing arthropod exposure to climatic fluctuations of surrounding habitats. Although facilitation is expected to increase under stressful conditions, empirical studies investigating the patterns of variation and magnitude of effects of ecosystem engineering at different spatial and temporal scales are still scarce. In this study we evaluated the facilitation consequences of leaf shelter created by gall-inducers on arthropod communities of Miconia ligustroides (DC.) Naudin (Melastomataceae). We evaluated how such effects change at the leaf and plant levels in an environment subject to strong climatic seasonality. The presence of leaf shelters on M. ligustroides increased arthropod diversity and biomass, modified the species composition at both the leaf and plant levels, and in wet and dry seasons. However, the addition of artificial leaf shelters during the dry season showed greater abundance, richness, and biomass of arthropods when com..., The raw data available here were used to run the data proposed in the following methodology.

Data sampling Leaf scale To evaluate the effects of leaf shelters on arthropod secondary colonization, 30 plants spaced approximately 10.0 m from each other were marked in the field in February 2020. All plants were between 1.0 and 1.5 m tall and had no flowers and fruits at the beginning of the study. In each plant, two pairs of leaves were selected as treatments (n = 4, artificial leaf rolls), and two pairs of leaves as control (n = 4, expanded leaves). We used different branches for each pair and marked the branches with colored tags (Figure 3). The treatment pairs consisted of a rolled leaf simulating a shelter created by D. gallaeformans (Figure 2d). We use young, intact, and fully developed leaves to create these artificial shelters. We opted to use intact leaves to create the shelters because th..., , # From leaves to whole plants: effects of shelter-builders on arthropod communities are stronger in dry seasons [https://doi.org/10.5061/dryad.9s4mw6mqz](https://doi.org/10.5061/dryad.9s4mw6mqz) ## **Explanations for the raw data tabs can also be found in the last tab (called Metadata) of the available XLSX files** **Metadata** **Dataset descriptors** **1) Leaf level** | **Variables** | **Description** | **Example** | | :-------------------- | :----------------------------------------------------------------------------------------------------------------------------- | :--------------------------------- | | Plant species | Specific epithet of plant taxa | *Miconia ligustroides* | | Group | Treatments used in th...叶栖庇护结构可充当微气候避难所，减轻节肢动物受周边生境气候波动的影响。尽管在胁迫环境下正相互作用预期会增强，但针对不同时空尺度下生态系统工程效应的变化模式与强度开展的实证研究仍较为匮乏。本研究针对造瘿昆虫构建的叶栖庇护结构对女贞叶野牡丹（*Miconia ligustroides* (DC.) Naudin，野牡丹科（Melastomataceae））节肢动物群落的促进效应展开评估。我们同时在叶片与植株两个尺度上，探究此类效应在具有强烈气候季节波动的生境中会发生何种变化。女贞叶野牡丹上叶栖庇护结构的存在，提升了节肢动物的多样性与生物量，同时改变了叶片与植株尺度下的物种组成，且该效应在湿季与旱季均存在。不过，在旱季添加人工叶栖庇护结构后，节肢动物的丰度、物种丰富度与生物量均显著更高[原文此处存在截断]。本研究公开的原始数据用于复现下述方法学中提出的数据分析流程。如需了解更多细节，请参阅已发表的研究论文，以及表1与补充信息S1。 ## 数据采样 ### 叶片尺度 为评估叶栖庇护结构对节肢动物次生定殖的影响，研究团队于2020年2月在野外标记了30株彼此间距约10.0米的植株。所有植株株高介于1.0至1.5米之间，且在研究初始阶段无花无果。每株植株选取两对叶片作为处理组（n=4，人工卷叶），另外两对叶片作为对照组（n=4，完全展开的叶片）。每对叶片取自不同的枝条，并使用彩色标签对枝条进行标记（图3）。 处理组的叶片为模拟*D. gallaeformans*构建的庇护结构而卷曲的叶片（图2d）。我们选取幼嫩、完整且完全展开的叶片制作人工庇护结构。本研究选择完整叶片制作庇护结构的原因因原文截断未完整呈现[原文此处存在截断]。 # 从叶片到整株植株：庇护构建者对节肢动物群落的效应在旱季更为显著 [https://doi.org/10.5061/dryad.9s4mw6mqz](https://doi.org/10.5061/dryad.9s4mw6mqz) **原始数据工作表的说明也可在提供的XLSX文件的最后一个工作表（名为Metadata）中找到** **Metadata** **数据集描述符** 1) 叶片尺度 | **变量名称** | **变量说明** | **示例** | | :-------------------- | :----------------------------------------------------------------------------------------------------------------------------- | :--------------------------------- | | 植物物种 | 植物类群的种加词 | *Miconia ligustroides* | | 分组 | 实验中使用的处理组[原文此处存在截断] | |
