Lemna minor; ammonium nitrogen; aquatic plants; biomass; calcium; culture media; fronds; introduced plants; invasive species; magnesium; nitrate nitrogen; nutrient availability; nutrients; phosphates; phosphorus
Abstract:
... Invasive alien plant species are usually characterized by a growth rate higher than their native competitors, and this higher rate can be achieved through the opportunistic use of plant nutrients. The growth of the invasive alien duckweed Lemna minuta and the co-generic native Lemna minor were compared under different conditions of nutrient availability. The two species were grown for one week und ...

Abstract:
... To determine factors limiting the distribution of two ecotypes of the annual legume Chamaecrista fasciculata along an abrupt flooding gradient, we quantified the relative importance of tolerance, intra-specific competition, and allocation patterns to vegetative and reproductive functions and their genetic basis. The ecotypes grow in dry upland and freshwater tidal marsh habitat, respectively. Into ...

Abstract:
... The availability of a photosynthetic carbon source may limit submersed plant growth, and experimental assessment of this limitation may depend on the volume available to belowground plant parts. To test the effect of pot size on submersed plant growth response to CO2 enrichment, we grew the freshwater macrophyte Vallisneria americana in pots containing 1.01, 2.25, and 4.04L of lake sediment in pH- ...

Abstract:
... Vernal pools, also termed temporary wetlands, promote key ecosystem services such as floodwater retention and provide unique habitat for many organisms. Despite their ecological value, vernal pools are declining worldwide. Because vernal pools are strongly influenced by variation in annual precipitation that fills the pools, climate change and alterations in precipitation regimes could drastically ...

Abstract:
... Charophytes are aquatic macrophytes with a complex morphology that belong to the Streptophytina phylum. The high degree of morphological plasticity in the genus Chara has led researchers to propose two competing species concepts, a micro- and macrospecies concept, the relevance of which we tested by phylogenetic analyses. We conducted a phylogenetic survey based on the phylogenetic relationships b ...

The subsection Willdenowia (Wood, 1962) of Grovesia is characterized by having the lowest branchlet segment without cortication. One species, Chara zeylanica sensu lato is attributed to the subsection Willdenowia. However, the taxonomy within this genus remains unclear due in part to the considerable overlap ...

Abstract:
... Phenotypic variability is a valuable adaptive mechanism for seagrass species that exist in a dynamic environment and can lead to significant intraspecific regional distinctions in life history. Research is lacking in studies examining the significance of within-species phenotypic variation in relation to gradients in environmental condition at a large spatial scale. These studies are essential to ...

Abstract:
... Submerged aquatic vegetation (SAV) that recruits from seed may be favored over species that maintain populations through clonal reproduction as estuaries become more dynamic under upstream hydrologic changes and sea level rise. We examined recruitment in an SAV species Ruppia maritima (wigeongrass) at the hydrologically variable Everglades-Florida Bay ecotone. We hypothesized that the R. maritima ...

Abstract:
... Bolboschoenus maritimus (alkali bulrush) is a globally distributed, clonal wetland plant. In the Great Salt Lake (GSL) Basin, USA, the focal region for this study, this species forms large, monotypic stands that provide critical wetland habitat for millions of migratory birds. I conducted a series of seed trait studies with B. maritimus seeds sourced from five GSL Basin populations. Seed viability ...
