Functional macrophyte trait variation as a response to the source of inorganic carbon acquisition.

ABSTRACT:

Background

This study aims to compare variation in a range of aquatic macrophyte species leaf traits into three carbon acquisition groups: HCO₃ ^-, free CO₂ and atmospheric CO₂.

Methods

The leaf functional traits were measured for 30 species from 30 softwater lakes. Macrophyte species were classified into (1) free CO₂, (2) atmospheric CO₂ and (3) bicarbonate HCO₃ ^- groups. In each lake we collected water samples and measured eight environmental variables: depth, Secchi depth, photosynthetically active radiation (PAR), pH of water, conductivity, calcium concentration, total nitrogen and total phosphorus. In this study we applied the RLQ analysis to investigate the relationships between spec
