Abstract
Over the past decades, several studies elucidated the effect of the loss of aquatic plant diversity in freshwater ecosystems. Several strategies and approaches for macrophytes diversity conservation have considered taxonomical or functional features, and only in the last years the evolutive dimension of plant communities was also considered [1]. Phylogenetic diversity (PD) dimension, reflecting the accumulation of genetic, phenotypic and phenological differences between evolutionary lineages, may have an important role in the biodiversity conservation. It reflects. Consequently, preserving sites with the greatest amount of phylogenetic variability will, in turn, preserve the greatest variation.in organismal features and, in some cases, functions [2]. Developing from 2020 and 2023, macroDIVERSITY project (PRIN 2017) aims at integrate spectral (SD) and phylogenetic (PD) diversity to map the functional diversity of freshwater macrophyte communities at different spatial scales and trophic gradients. Within the framework of macroDIVERSITY, , we will collect data on macrophyte diversity from plots sampled over selected lakes in Central and Northern Ital, based on robust experimental design. The PD of each plot will be quantified using the Faith's metric. The Net Relatedness index (NRI) and the Nearest Taxon Index (NTI) will also be used to quantify the degree of the community phylogenetic clustering/overdispersion among species within each plot [3]. Using the described approach, we aim to 1) delineate the evolutionary relationships within the wetland communities; 2) obtain PD metrics of each macrophyte community/ecosystem; 3) achieve a feedback on wetlands genetic sustainability of Central and Northern Italy.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
