Protist Dispersal Detection: University of Michigan Biological Station, July 2024

This dataset contains the results of a field dispersal array assembled in Gates Bog, Pellston, Michigan. The data were collected by a graduate student, and consist of measurements of protist presence or absence in 1mL fluid samples taken from pitcher plants and centrifuge tubes in the array. The dataset contains both initial protist detection from the fluid samples, as well as detection after a 24 hour incubation period. The dataset also contains the positions of each plant and tube used for sample collection and their distances from the established source population at the center of the array. We used the purple pitcher plant, Sarracenia purpurea, as a model system to explore questions of specialist protist dispersal. Newly opened pitchers are sterile, providing virgin habitat open to community assembly of highly specialized protist species (Peterson 2008). The placement of a known community of protists at the center of an uncolonized array of habitat patches allows us to identify both sources and destinations of dispersing microbes in the array. The purpose of this study is to measure dispersal rates for a subset of pitcher plant protist species.

本数据集收录了密歇根州佩尔斯顿市盖茨沼泽（Gates Bog）内搭建的野外扩散阵列实验所得数据。本数据由一名研究生采集，涵盖从阵列内瓶子草（pitcher plant）及离心管中获取的1毫升液体样本的原生生物（protist）存在/缺失检测结果。本数据集既包含液体样本的原生生物初始检测结果，也包含24小时培养后的检测结果。此外，数据集还收录了样本采集所用的全部瓶子草与离心管的位置信息，以及各采样点与阵列中心已建立的源种群之间的距离。我们以紫瓶子草（Sarracenia purpurea，俗称purple pitcher plant）作为模式系统，探究专化型原生生物的扩散相关科学问题。刚展开的瓶子草笼无菌，可为高度特化的原生生物类群的群落构建提供未被扰动的全新生境（Peterson, 2008）。将已知原生生物群落定植于未被占领的生境斑块阵列的中心，可使我们明确该阵列内扩散微生物的来源与去向。本研究旨在测定部分瓶子草原生生物类群的扩散速率。
