Contrasting effects of native riparian and non-native plantation-tree litter on survival and case construction by a stream caddisfly

This dataset contains the raw experimental data associated with the study “Contrasting effects of native riparian and non-native plantation-tree litter on survival and case construction by a stream caddisfly.” The experiment evaluated the responses of 60 larvae of the caddisfly Austrocentrus griseus (Trichoptera) exposed to six treatments differing in the availability of native Chusquea quila, non-native plantation species Eucalyptus globulus and Pinus radiata, and inorganic substrate. The experiment was conducted in spring 2022 using organisms collected from Pehuenco Stream, Nahuelbuta National Park, south-central Chile. The dataset includes repeated observations of survival and case construction over 142.46 h, together with initial and final body mass, metabolic rate, material mass, case traits (mass, puncture resistance, length, and width), and case composition. A data dictionary provides definitions, units, and codes for all variables. The dataset is organized using unique individual identifiers to facilitate integration among data tables and reproducible analyses.本数据集包含与研究《本土河岸植物凋落物与外来人工林植物凋落物对溪流石蛾存活与筑壳行为的差异化影响》相关的原始实验数据。本实验针对60头灰澳石蛾（Austrocentrus griseus，毛翅目Trichoptera）幼虫设置6种处理组，各组在本土物种智利箭竹（Chusquea quila）、外来人工林树种蓝桉（Eucalyptus globulus）、辐射松（Pinus radiata）以及无机基质的可获得性上存在差异，以此评估幼虫对各处理的响应。实验于2022年春季开展，所用受试生物采集自智利中南部的纳韦尔武塔国家公园（Nahuelbuta National Park）佩温科溪（Pehuenco Stream）。本数据集涵盖142.46小时内针对存活情况与筑壳行为的重复观测数据，同时包含初测与终测体质量、代谢率、材料质量、护壳性状（质量、抗穿刺性、长度与宽度）以及护壳组成信息。本数据集附带数据字典，对所有变量的定义、单位与编码进行说明。数据集通过唯一个体标识符进行组织，便于各数据表间的整合与可重复分析。
