Seagrass ecosystem multifunctionality under the rise of a flagship marine megaherbivore

Marjolijn J. A. Christianen et al.

Summary: Changes in megaherbivore populations have a significant impact on ecosystem multifunctionality, with intermediate grazing intensity resulting in the highest rates of nutrient cycling and carbon storage, while intense grazing leads to disproportionate effects on ecosystem functions and a collapse in multifunctionality.

Green turtles shape the seascape through grazing patch formation around habitat features: Experimental evidence

F. O. H. Smulders et al.

Summary: Understanding how herbivores shape the landscape is important and studying how they incorporate habitat features into their foraging behavior is crucial. However, there is limited knowledge about the influence of habitat structure on megaherbivore grazing in marine ecosystems. In this study, we introduced artificial structures at different scales in a seagrass meadow to investigate the response of green turtles. The results showed that the turtles significantly increased in density and mainly grazed and rested in the areas with structures, resulting in changes in seagrass bed structure and heterogeneity at the landscape scale.

Fish grazing enhanced by nutrient enrichment may limit invasive seagrass expansion

Fee O. H. Smulders et al.

Summary: The success of invasive macrophytes is influenced by nutrient availability and consumer pressure. This study found that nutrient enrichment decreased invasive leaf carbon:nitrogen ratios and highlighted the role of diverse and abundant herbivore communities in limiting invasion success. Top-down control by native fish communities may counteract eutrophication effects on invasive seagrass leaves.

Long-term declines and recovery of meadow area across the world's seagrass bioregions

Jillian C. Dunic et al.

Summary: Seagrass meadows globally are facing increasing threats, with overall declining trends in area, although stabilization or reversal of trends has been observed in some bioregions. Studies have identified a variety of drivers influencing seagrass meadow changes, highlighting the need for a better understanding of causes to improve management.

Sequential overgrazing by green turtles causes archipelago-wide functional extinctions of seagrass meadows

Mayuresh Gangal et al.

Summary: After experiencing centuries of decline, green turtle populations have shown localized recoveries due to conservation efforts, but their herbivory on seagrass meadows has led to long-term impacts, potentially causing functional extinction of seagrass ecosystems.
