Long-term minnow community data from the Bayou Pierre, Mississippi

Long-term community monitoring is becoming an important tool for
ecological studies. Historical data are present in a variety of sources
but often require considerable effort to extract, filter, and verify prior
to analyses. In this dataset we document minnow (sensu lato, Cyprinidae +
Leuciscidae) communities in the Bayou Pierre, Mississippi. We include
filtered community data from twelve localities and three time periods
(1974-75, 1985-89, 2019-20) derived from a mixture of literature, museum
collections, and contemporary collecting efforts. All collections were
made using comparable methodologies. We also include an additional 29
contemporary collections which do not have historical representation but
which cover the majority of the watershed. We further include a trait
database coded from literature values which captures both reproductive and
ecological traits for the species in these data. These data were used in
preparation of a manuscript examining long-term taxonomic, ecological, and
functional change within the minnows in the Bayou Pierre, and they are
part of a broader research effort to study the effects of fluvial
geomorphic evolution on aquatic ecosystems.

长期群落监测正逐渐成为生态学研究的重要手段。历史数据来源多样，但在开展分析前往往需要投入大量精力进行提取、筛选与验证。本数据集记录了密西西比州贝湾皮埃尔河（Bayou Pierre）的广义雅罗鱼（sensu lato，鲤科Cyprinidae + 雅罗鱼科Leuciscidae）群落。数据集包含经筛选的群落数据，涵盖12个采样点与3个时间阶段（1974-1975年、1985-1989年、2019-2020年），数据来源整合了文献记录、博物馆馆藏以及当代采样工作。所有采样均采用统一可比的方法完成。此外，数据集还新增29组当代采样数据，此类采样无历史对应记录，但覆盖了该流域的绝大部分区域。本数据集还附带一份基于文献值编码的性状数据库，收录了本数据涉及物种的繁殖与生态性状。本数据曾用于撰写一篇探讨贝湾皮埃尔河雅罗鱼群落长期分类学、生态学及功能性状变化的研究论文，同时也是一项更广泛研究项目的组成部分——该项目旨在探究河流地貌演化对水生生态系统的影响。
