Photorespiration and carbon limitation determine productivity in temperate seagrasses. [PDF]

PLoS ONE, 2013
The gross primary productivity of two seagrasses, Zostera marina and Ruppia maritima, and one green macroalga, Ulva intestinalis, was assessed in laboratory and field experiments to determine whether the photorespiratory pathway operates at a substantial

Seasonal variability and seagrass traits affect methane fluxes in a subtropical meadow

Journal of Ecology, Volume 112, Issue 12, Page 2771-2784, December 2024.
These results indicate that within‐species more so than between‐species trait variability drives the direction and magnitude of CH4 fluxes in seagrass meadows. The authors identified a trade‐off where seagrass biomass is often associated with enhanced sediment carbon storage, but in this study, plant size promoted CH4 production, potentially offsetting

Exploring the Potential of Seed‐Based Dwarf Eelgrass (Zostera noltii) Restoration

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 9, September 2024.
ABSTRACT Dwarf eelgrass, Zostera noltii, is an important ecosystem engineer that creates dense meadows along the coasts of Europe and Northwest Africa. During the last century, this seagrass species suffered severe population declines, and to counteract these losses, restoration has emerged as an important management tool. Thus far, restoration efforts

Species composition and distribution of microalgae in the Sukhodol River estuary (Ussury Bay, Peter the Great Bay) in autumn. 2. Epiphyton

Известия ТИНРО, 2014
Epiphyte microalgae from common macrophytes ( Zostera marina, Z. japonica, Ruppia maritima, Ulva prolifera, Gracilaria verrucosa, Cladophora glomerata, Phragmites australis ) were sampled in the Sukhodol estuary in September of 2012. In total, 46 taxa of

Diet composition and feeding strategy of the southern pipefish Syngnathus folletti in a Widgeon grass bed of the Patos Lagoon Estuary, RS, Brazil

Neotropical Ichthyology
Pipefish species are poorly known representatives of the family Syngnathidae, which have been increasingly threatened by anthropogenic activities. We describe the diet composition and feeding strategy of southern pipefish Syngnathus folletti inhabiting a

Salinity and water clarity dictate seasonal variability in coastal submerged aquatic vegetation in subtropical estuarine environments

Aquatic Biology, 2019
Spatial and temporal variability characterize submerged aquatic vegetation (SAV) assemblages, but understanding the complex interactions of environmental drivers of SAV assemblages remains elusive.

Physiological effects of short-term salinity changes on Ruppia maritima

Aquatic Botany, 2003
Changes in Ruppia maritimaL. leaf-tissue osmolality, compatible solute synthesis in leaf tissues, and maximum effective quantum yield in response to short-term changes in salinity were investigated. Plants cultured at 20‰ S were exposed to 0‰ S, 10‰ S (half-ambient), 20‰ S (ambient), and 40‰ S (twice-ambient) salinities.

Seagrass recovery trajectories and recovery potential in relation to nutrient reduction

Journal of Applied Ecology, Volume 61, Issue 8, Page 1784-1804, August 2024.
Within a large seascape (15,000 km2) the least eutrophicated region showed seagrass recovery upon nutrient reduction. We translated the critical riverine nutrient loads for this recovery, via regional eutrophication indicators, to loads that may enable a sustained recovery in the other regions.
