Abstract

Freshwater mussels are filter feeders that play an integral role in keeping our water systems healthy. Filter feeding influences the entire ecosystem through the transfer of energy, cycling of nutrients, and purification of water. Freshwater mussels form multispecies assemblages which may lead to food resource competition among species. This study focuses on determining which suspended food resources freshwater mussels consume and evaluates if, and to what extent, mussels in a multispecies bed are partitioning available food resources. We examined the available food resources consumed by four species of freshwater mussels, Bleufer (Potamilus purpuratus), Pistolgrip (Tritogonia verrucose), Texas Pigtoe (Fusconaia askewi), and Yellow Sandshell (Lampsilis teres), from a single mussel bed in the upper Sabine River of East Texas. Using eDNA as a measure of food availability, we found that bacteria were consumed at a higher richness and diversity than phytoplankton or zooplankton. Furthermore, we found low niche overlap of bacteria between mussel species suggesting niche partitioning may be common for freshwater mussels despite being found in a flowing river environment with potentially unlimited resources. We also found that the richness and diversity of bacteria consumed by the Yellow Sandshell is statistically higher than Pistolgrip and that these species have moderate niche overlap (0.556). These data and previous habitat data indicate that the Pistolgrip can be classified as an ecological specialist species and the Yellow Sandshell as an ecological generalist species. Overall, these results support ecological theory that mussels co-exist in the same environment because they utilize different resources.

德克萨斯州萨宾河多物种贻贝床中淡水贻贝食物资源的生态位分配
淡水贻贝是滤食性动物,在保持我们的水系统健康方面发挥着不可或缺的作用。滤食通过能量的转移、营养物质的循环和水的净化来影响整个生态系统。淡水贻贝形成多物种群落,可能导致物种间的食物资源竞争。本研究的重点是确定淡水贻贝消耗的悬浮食物资源,并评估多物种床中的贻贝是否以及在多大程度上分配了可用的食物资源。在美国德克萨斯州东部萨宾河上游的单一贻贝床上,研究了四种淡水贻贝(Bleufer, Potamilus purpuratus)、Pistolgrip (Tritogonia verrucose)、Texas Pigtoe (Fusconaia askewi)和Yellow Sandshell (Lampsilis teres)的可利用食物资源。使用eDNA作为食物可用性的衡量标准,我们发现细菌被消耗的丰富度和多样性高于浮游植物或浮游动物。此外,我们发现贻贝物种之间的细菌生态位重叠程度很低,这表明尽管淡水贻贝生活在具有潜在无限资源的流动河流环境中,但生态位分配可能在淡水贻贝中很常见。黄沙蛤消耗的细菌丰富度和多样性均高于手枪蛤,两者有适度的生态位重叠(0.556)。这些数据和以往的生境数据表明,可将Pistolgrip分类为生态专门性物种,而将黄沙壳分类为生态通才物种。总的来说,这些结果支持了贻贝在同一环境中共存的生态学理论,因为它们利用不同的资源。

期刊介绍: Aquatic Ecology publishes timely, peer-reviewed original papers relating to the ecology of fresh, brackish, estuarine and marine environments. Papers on fundamental and applied novel research in both the field and the laboratory, including descriptive or experimental studies, will be included in the journal. Preference will be given to studies that address timely and current topics and are integrative and critical in approach. We discourage papers that describe presence and abundance of aquatic biota in local habitats as well as papers that are pure systematic. The journal provides a forum for the aquatic ecologist - limnologist and oceanologist alike- to discuss ecological issues related to processes and structures at different integration levels from individuals to populations, to communities and entire ecosystems.
