A review of seagrass detection, mapping and monitoring applications using acoustic systems [PDF]

European Journal of Remote Sensing, 2019
Seagrass meadows are key elements of marine ecosystems as they affect the physical, chemical and biological environment and provide habitats for fish and invertebrates.

Seagrass: A Dynamic System [PDF]

, 2021
<p>Small herbivorous invertebrates consume algal epiphytes, reducing negative effects (e.g. shading) on seagrass. Much research to date has focused on crustacean grazers, and comparatively little on gastropods. The aim of this research was to 1) examine seasonal and spatial variation in seagrass and associated gastropods in a large, tidal estuary

Functionally Rich Fish Assemblages Support Greater Rates of Multiple Ecological Functions in Seagrass Meadows. [PDF]

Ecol Evol
We show that the functional diversity of fishes promotes multifunctionality in seagrass meadows. We found that there was consistency in the seascape context and connectivity variables that structured the rate and distribution of different components of functioning and the functional diversity of fish in seagrass meadows.

Understanding seagrass resilience in temperate systems: the importance of timing of the disturbance [PDF]

Ecological Indicators, 2016
Temperate seagrass meadows form valuable ecosystems in coastal environments and present a distinct seasonal growth. They are threatened by an increasing amount of stressors, potentially affecting their capacity to recover from disturbances. We hypothesized that their resilience to disturbances is affected by seasonal dynamics.

Local Ecological Knowledge Reveals Change in Seagrass Social–Ecological Systems

Oceans, 2022
It is widely recognized that humanity is currently facing multiple planetary crises, including the widespread loss of biodiversity and a rapidly changing climate. The impacts of these crises are often far reaching and threaten food security (SDG goal two: zero hunger).

Tidal controls on trace gas dynamics in a seagrass meadow of the Ria Formosa lagoon (southern Portugal) [PDF]

, 2014
Coastal zones are important source regions for a variety of trace gases, including halocarbons and sulfur-bearing species. While salt marshes, macroalgae and phyto-plankton communities have been intensively studied, little is known about trace gas fluxes

Non-native red alga Gracilaria vermiculophylla compensates for seagrass loss as blue crab nursery habitat in the emerging Chesapeake Bay ecosystem

PLoS ONE, 2022
Non-native species can become deleterious or potentially beneficial as components of novel ecosystems. The non-native red macroalga Gracilaria vermiculophylla may provide nursery habitat where eelgrass Zostera marina has been extirpated in Chesapeake Bay.

Spatial and Temporal Patterns in Macroherbivore Grazing in a Multi-Species Tropical Seagrass Meadow of the Great Barrier Reef

Diversity, 2021
Macroherbivory is an important process in seagrass meadows worldwide; however, the impact of macroherbivores on seagrasses in the Great Barrier Reef (GBR) has received little attention.

Seasonal links between metabolites and traditional seagrass metrics in the seagrass Halophila ovalis in an estuarine system

Ecological Indicators, 2022
Monitoring of seagrasses has mainly relied on traditional seagrass metrics (e.g., biomass), which deliver reliable information about mortality but are unable to inform about impacts on seagrass health at the very early stages of stress exposure. Metabolomics is a novel molecular technique which can be used for early stress-detection in plants and also ...

Seasonal Fluctuations of the Seagrass Holobiont under Contrasting Environmental Conditions. [PDF]

Environ Microbiol Rep
(A) The inharmonious state of the Coorong and the different sample types collect with throughout this study. (B, C) Biofilm, including the presence of diatoms and bacteria, attached on the leaves of Ruppia. ABSTRACT Microbial communities are widely recognised as indicative of ecosystem health.
