Marsh Ecology Research Program (MERP): Metaphyton data (1985-1989)

The Marsh Ecology Research Program (MERP) was a long-term interdisciplinary study on the ecology of prairie wetlands. A scientific team from a variety of disciplines (hydrology, plant ecology, invertebrate ecology, vertebrate ecology, nutrient dynamics, marsh management) was assembled to design and oversee a long-term experiment on the effects of water-level manipulation on northern prairie wetlands. Ten years of fieldwork (1980 -1989), combining a routine long-term monitoring program and a series of short-term studies, generated a wealth of new and diverse information on the ecology and function of prairie wetlands (Murkin, Batt, Caldwell, Kadlec and van der Valk, 2000). This data set includes phytoplankton data, collected as part of the algae secion of MERP. The objectives of the Marsh Ecology Research Program algal study were to unveil a better understanding on how different algae assemblages contribute to primary production (measured as C-assimilation rates) and biomass (chlorophyll-a content) in a prairie marsh habitat. The undertaking of this study also aimed to show how algal biomass would change with varying water depth, macrophyte density, and light attenuation. This unique project allowed for the productivity of these algal communities to be compared with that of the macrophyte community in order to demonstrate their importance in sustaining prairie wetland food webs (Robinson et al., 1997a).

沼泽生态学研究计划（Marsh Ecology Research Program, MERP）是一项针对草原湿地生态的长期跨学科研究。该计划组建了一支涵盖水文学、植物生态学、无脊椎动物生态学、脊椎动物生态学、营养动力学、沼泽管理学的多学科科研团队，旨在设计并监管一项针对北方草原湿地水位调控效应的长期实验。1980年至1989年的十年野外工作中，研究团队结合常规长期监测计划与一系列短期研究，积累了大量有关草原湿地生态与功能的新颖多样的研究成果（Murkin、Batt、Caldwell、Kadlec与van der Valk，2000）。

本数据集包含作为MERP藻类研究组成部分采集的浮游植物（phytoplankton）数据。沼泽生态学研究计划的藻类研究目标为：深化对不同藻类群落如何助力草原沼泽生境初级生产力（以碳同化速率（C-assimilation rates）衡量）与生物量（以叶绿素-a（chlorophyll-a）含量表征）的认知；同时阐明藻类生物量如何随水深、大型植物（macrophyte）密度与光衰减程度发生变化。这项独特的研究还可将此类藻类群落的生产力与大型植物群落的生产力进行对比，以彰显二者在维持草原湿地食物网中的重要性（Robinson等，1997a）。
