Accelerating loss of seagrasses across the globe threatens coastal ecosystems
This comprehensive global assessment of 215 studies found that seagrasses have been disappearing at a rate of 110 km2 yr−1 since 1980 and that 29% of the known areal extent has disappeared since seagRass areas were initially recorded in 1879. Expand
The impacts of climate change in coastal marine systems.
Key directions for future research include identifying key demographic transitions that influence population dynamics, predicting changes in the community-level impacts of ecologically dominant species, incorporating populations' ability to evolve (adapt), and understanding the scales over which climate will change and living systems will respond.

Biological invasions: recommendations for U.S. policy and management.
The Ecological Society of America recommends that the federal government take the following six actions: use new information and practices to better manage commercial and other pathways to reduce the transport and release of potentially harmful species, and establish a National Center for Invasive Species Management.

Anthropogenic debris in seafood: Plastic debris and fibers from textiles in fish and bivalves sold for human consumption
Some of the first findings of plastic debris in fishes directly sold for human consumption raising concerns regarding human health are reported. Expand
Marine range shifts and species introductions: comparative spread rates and community impacts
This work examined how the understanding of range shifts may be informed by the more established study of non-native species introductions, and found that spread rates ofrange shifts were lower than those of functionally similar introduced species having ecologically similar impacts. Expand
Beyond ballast water: aquarium and ornamental trades as sources of invasive species in aquatic ecosystems
Although ballast water has received much attention as a source of aquatic invasive species, aquariums and trade in aquarium and ornamental species are emerging as another important source for speciesExpand
A Global Review of the Distribution, Taxonomy, and Impacts of Introduced Seaweeds
Using binomial tests it is shown that several algal families contain more successful invaders than would be expected by chance, highlighting groups that should be targeted for management. Expand
Relative effects of grazers and nutrients on seagrasses: a meta-analysis approach
Meta-analyses of 35 published seagrass studies used to compare the relative strength of 'top-down' grazer effects and 'bottom-up' nutrient effects on epiphyte biomass and segrass above-ground growth rate, above- ground biomass, below-ground biomass, and shoot density revealed positive effects of grazing on seagRass response variables and corresponding negative impacts on epi- phyte biomass.

Introduced species in seagrass ecosystems: Status and concerns
More definitive studies are required to elucidate the relative effects of nutrient pollution and introduced species in causing seagrass decline, particularly where reduced herbivory and boating activity also covary. Expand
