摘要

摘要对新热带地区水生植物和水生生态系统相关植物区系的研究表明,同一植物科在不同气候条件下占优势或共生。解释这种组合中具有非随机模式的群体共同出现的一种方法是了解它们的系统发育结构。在此,我们提出了一项调查,研究了巴西东北部热带气候序列中与水库相关的植物的系统发育组合规则。研究了8个干雨期地区的气候、化学和微量元素特征,以及它们组合的丰富度、多样性和系统发育结构。以豆科、禾本科和苏科植物为主,特别是在边境地区。在调查的物种中,我们强调了具有两栖生活型、自栖型分散综合征和地理分布模式广泛的分类群。我们观察到,季节效应支配着系统发育结构的模式,具有非共熟悉的趋势。水质和沉积物是最有效的非生物因子,是系统发育指标丰富度和变化的预测因子。从这个意义上说,由于非随机性,在组合中确定的家庭共现性不如预期的确定性,因为从时间上看,行会的结构明显是季节性的。

Phylogenetic structure of aquatic plant assemblages in a climate sequence
Abstract Floristic studies of aquatic plants and flora associated with aquatic ecosystems carried out in the Neotropical region have demonstrated the predominance and co-occurrence of the same plant families under different climatic conditions. One way to interpret this co-occurrence of groups with non-random patterns in assemblages is to understand their phylogenetic structure. Herein, we present an investigation that studied the rule of phylogenetic assembly on plants associated with reservoirs in a tropical climosequence in Northeast Brazil. We studied eight areas during the dry and rainy periods and characterized their climatic, chemical, and trace elements, as well as richness, diversity, and phylogenetic structure of their assemblages. We found a predominance of the families Fabaceae, Poaceae and Cyperaceae, especially in border areas. Among the species surveyed, we highlight those with amphibian life-form, autochoric-type dispersion syndrome and the taxa with patterns of wide geographical distribution. We observed that the seasonal effect ruled patterns of phylogenetic structure with tendency for non-co-familiarity. Water quality and sediment were the abiotic factors most efficient as predictors of richness and variations in phylogenetic metrics. In this sense, the family co-occurrence identified in the assemblages was less deterministic than expected through non-randomness, because temporally, guilds were distinctly structured in function of seasonality.
