Germination and Algal-Free Laboratory Culture of Widgeon Grass, Ruppia maritima

Estuaries, 1984
A methodology for the isolation ofRuppia maritima L. into algal-free laboratory culture is described. Seeds were surface sterilized with 96% ethyl alcohol of pH 2, kept for several months in cold storage at 7°C, and subsequently transferred to 25°C to induce germination.

Germination ecology of two Ruppia maritima L. populations in Southern Brazil

Aquatic Botany, 1988
The seed germination of two Ruppia maritima L. populations, was studied under controlled conditions. Seeds from an ephemeral habitat germinated best after being dried, while high temperatures and low salinities induced germination in seeds from a more stable habitat.

Development and characterization of microsatellite loci in Ruppia maritima L. (Ruppiaceae)

Conservation Genetics Resources, 2009
Ruppia maritima L. (Ruppiaceae), a monoecious seagrass, is widely distributed in temperate and tropical regions. In this paper, we reported ten polymorphic microsatellite loci developed for this species. The number of alleles per locus ranged from 2 to 7, and the expected heterozygosity ranged from 0.240 to 0.701.

Comprehensive phylogenetic analyses of the Ruppia maritima complex focusing on taxa from the Mediterranean

Journal of Plant Research, 2013
Recent molecular phylogenetic studies reported high diversity of Ruppia species in the Mediterranean. Multiple taxa, including apparent endemics, are known from that region, however, they have thus far not been exposed to phylogenetic analyses aimed at studying their relationships to taxa from other parts of the world.

Structural characteristics of a diatom community epiphytic on Ruppia maritima

Hydrobiologia, 1977
Epiphytic diatoms were collected from both the leaves and internodes of Ruppia maritima in a New Jersey salt marsh during the growing season of the host plant. Community diversity (H′ and the number of diatom taxa) values were initially high as Ruppia began its growth, but quickly dropped to sustained low levels as vegetative growth of the host ceased ...

Rhizosphere O2 dynamics in young Zostera marina and Ruppia maritima

Marine Ecology Progress Series, 2015
Zostera marina and Ruppia maritima often share the same habitat, but R. maritima appears more resistant to environmental stress. We investigated the impact of light intensity and water column O2 concentrations on radial oxygen loss (ROL), in young specimens of Z. marina and R. maritima. Planar optode imaging revealed that ROL of Z. marina was localized

Ruppia maritima L. seed bank viability at the Everglades-Florida Bay ecotone

Aquatic Botany, 2013
Abstract Ruppia maritima L. is a cosmopolitan habitat-forming seagrass species that historically dominated at the Everglades-Florida Bay ecotone in the Greater Everglades Ecosystem. Currently, however, this species exhibits a patchy and ephemeral distribution which results in a degraded habitat.

Culture studies of Ruppia maritima L. in bicarbonate- and sucrose-based media

Journal of Experimental Marine Biology and Ecology, 1996
Abstract Media were compared for culture of the estuarine plant Ruppia maritima L. The best inorganic nutrient amendment was based on f/2 basal enrichment salts in artificial seawater. Using f/2 basal enrichments, Ruppia maritima could be grown in media where either bicarbonate or sucrose was provided as the major carbon source.

Cultivation Guide for Ruppia maritima from Seeds

Ruppia maritima L. (Wigeongrass) is a euryhaline submerged aquatic vegetation (SAV) and one of the seven seagrass species found in the Indian River Lagoon (IRL), Florida. Unlike other seagrass species,This guide provides protocol for cultivating R. maritima in a laboratory or a seagrass nursery from field-collected seeds.
