Rapid shifts in bryophyte phenology revealed by airborne eDNA

In our publication, “Rapid shifts in bryophyte phenology revealed by airborne eDNA”, we report on multi-decadal shifts in the phenology of spore dispersal in 16 bryophyte taxa based on the data deposited here. The dataset represents a subset of a unique 35-year time series of airborne environmental DNA (eDNA ) collected in Kiruna, northern Sweden. The observed phenological shifts indicate strong perturbations in bryophyte phenology, consistent with ongoing climate change, and demonstrate that the use of airborne particles analysed by eDNA methodology is a valuable complement to other monitoring methods. The main dataset provided here consists of pivot coordinates of relative abundance data for the selected taxa between 1974 and 2008. The time series comprises data for every week when mean temperatures reached 0 °C, for every second year. Environmental DNA was extracted from archived samples of air filters that had been collected weekly since the 1960s and stored in air-tight containers...., , # Data from: Rapid shifts in bryophyte phenology revealed by airborne eDNA

## Description of the data and file structure

We provide two data sheets. The first contains a time-series (1974-2008) of weekly pivot coordinates representing eDNA based relative abundance data from 16 bryophyte taxa. The dataset is a subset of that used in the preprint Sullivan et al. (2023; [https://doi.org/10.1101/2023.12.06.569882](https://doi.org/10.1101/2023.12.06.569882)) that includes all organism groups detected in the samples. The eDNA was obtained from airborn particles captured in air filters collected in northern Sweden and subsequently sequenced. The second file contains local weather data from the site for the same period as the eDNA time series. Variables include weekly precipitation and temperature, obtained from the Swedish Meteorological and Hydrological Institute (SMHI).

在我们发表于《通过空气传播环境DNA揭示的苔藓植物物候快速变化》（*Rapid shifts in bryophyte phenology revealed by airborne eDNA*）的研究中，我们基于本数据集收录的原始数据，报告了16个苔藓植物（bryophyte）类群的孢子传播物候在数十年间的变化趋势。本数据集为瑞典北部基律纳（Kiruna）地区采集的、时长35年的独特空气传播环境DNA（environmental DNA, eDNA）时间序列的子集。

观测到的物候变化表明苔藓植物物候受到强烈扰动，这与当前持续进行的气候变化趋势相符，同时也证明了通过环境DNA方法分析空气传播颗粒物的技术手段，可作为其他传统监测方法的重要补充。

本数据集提供的核心数据为1974年至2008年间各选定类群相对丰度数据的枢轴坐标。该时间序列仅包含当周平均气温达到0℃的周度数据，且采样频率为每两年一次。环境DNA提取自1960年代起每周采集、并以气密容器储存的空气过滤器存档样本。

## 数据与文件结构说明
我们共提供两份数据表。第一份包含1974年至2008年的周度数据序列，即基于环境DNA的16个苔藓植物类群相对丰度数据的枢轴坐标。本数据集为预印本Sullivan等人（2023; [https://doi.org/10.1101/2023.12.06.569882](https://doi.org/10.1101/2023.12.06.569882)）中使用的全部数据集的子集，后者涵盖了样本中检测到的所有生物类群。环境DNA取自瑞典北部地区采集的空气过滤器所捕获的空气传播颗粒物，并经后续测序获得。第二份文件包含与eDNA时间序列同期的该研究站点的本地气象数据，变量包括每周降水量与气温，数据由瑞典气象与水文研究所（Swedish Meteorological and Hydrological Institute, SMHI）提供。
