Abstract

Abstract - Phytoplankton assemblages are of great importance as indicators of water quality. However, knowledge of New Jersey freshwater phytoplankton assemblages is very limited. We collected a total of 196 samples between June and October each year from 2016 to 2019 and analyzed them for water-quality parameters, microcystins, and phytoplankton community composition. We documented a total of 91 phytoplankton taxa. The cyanophytes were the most dominant phytoplankton group statewide and by ecoregion, with Synechococcus being the most frequently observed cyanophyte. Fluorescence of phycocyanin significantly correlated with cyanobacterial cell density and microcystins, suggesting phycocyanin can be used as a proxy for estimating harmful cyanobacterial blooms (HCB) conditions. The results of this study provide insight into the freshwater phytoplankton communities during the HCB season and their relationship with water-quality conditions in New Jersey.

新泽西州淡水夏季浮游植物群落和有害蓝藻水华

摘要-浮游植物群落作为水质指标具有重要意义。然而，对新泽西州淡水浮游植物群落的了解非常有限。从2016年到2019年，我们在每年6月至10月期间总共收集了196个样本，并对其水质参数、微囊藻毒素和浮游植物群落组成进行了分析。我们总共记录了91个浮游植物分类群。蓝藻是全州和生态区内最具优势的浮游植物群，聚球藻是最常见的蓝藻。藻蓝蛋白的荧光与蓝藻细胞密度和微囊藻毒素显著相关，表明藻蓝蛋白可作为估计有害蓝藻水华（HCB）条件的指标。这项研究的结果为深入了解HCB季节的淡水浮游植物群落及其与新泽西州水质状况的关系提供了依据。

期刊介绍： The Northeastern Naturalist covers all aspects of the natural history sciences of terrestrial, freshwater, and marine organisms and the environments of the northeastern portion of North America, roughly bounded from Virginia to Missouri, north to Minnesota and Nunavut, east to Newfoundland, and south back to Virginia. Manuscripts based on field studies outside of this region that provide information on species within this region may be considered at the Editor’s discretion. The journal welcomes manuscripts based on observations and research focused on the biology of terrestrial, freshwater, and marine organisms and communities as it relates to their life histories and their function within, use of, and adaptation to the environment and the habitats in which they are found, as well as on the ecology and conservation of species and habitats. Such studies may encompass measurements, surveys, and/or experiments in the field, under lab conditions, or utilizing museum and herbarium specimens. Subject areas include, but are not limited to, anatomy, behavior, biogeography, biology, conservation, evolution, ecology, genetics, parasitology, physiology, population biology, and taxonomy. Strict lab, modeling, and simulation studies on natural history aspects of the region, without any field component, will be considered for publication as long as the research has direct and clear significance to field naturalists and the manuscript discusses these implications.
