Abstract

Abstract: Aim Positive relationships between occupancy and abundance are often found for different groups of organisms and ecosystem types. However, to our knowledge, no study has sought to assess this relationship considering a context in which a particular mechanism is the most likely explanation. In this study, in addition to the positive relationship with abundance, we tested the hypothesis that occupancy of zooplankton species should be greater during the flood season because in this period the hydrological connectivity is greater than in the dry season, facilitating passive dispersal between floodplain environments. Methods Our study was carried out at 52 sites - including lakes and rivers - on the Araguaia River floodplain. We used an analysis of covariance to test the effects of abundance and hydrological period on zooplankton occupancy. Results We found, as expected, a positive relationship between occupancy and abundance of zooplankton species in each hydrological period. Our results also indicated that, with the increase in abundance, species occupancies were higher in the flood than in the dry season. Conclusions The positive effect of the flood on zooplankton occupancy can be explained by the increase in water level that increases the hydrological connectivity and the potential for plankton passive dispersal.

在洪泛区浮游动物的占有与丰度之间的关系是由水文制度介导的
摘要:目的在不同的生物类群和生态系统类型中,占有与丰度之间存在正相关关系。然而,据我们所知,没有研究试图评估这种关系,考虑到一个特定的机制是最可能的解释。在本研究中,除了与丰度呈正相关外,我们还检验了一个假设,即在汛期浮游动物物种的占用应该更大,因为在这个时期,水文连通性比旱季更大,有利于洪泛平原环境之间的被动扩散。我们的研究在阿拉瓜亚河漫滩上的52个地点进行,包括湖泊和河流。我们使用协方差分析来检验丰度和水文周期对浮游动物占用的影响。结果各水文期浮游动物物种的占有与丰度呈正相关关系。结果还表明,随着丰度的增加,丰水期物种占用率高于枯水期。结论洪水对浮游动物占用的积极影响可以解释为水位的上升,增加了水文连通性和浮游生物被动扩散的可能性。
