Plumbing the Global Carbon Cycle: Integrating Inland Waters into the Terrestrial Carbon Budget
A BSTRACTBecause freshwater covers such a small fraction of the Earth’s surface area, inland freshwater ecosystems (particularly lakes, rivers, and reservoirs) have rarely been considered as
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.
A blueprint for blue carbon: toward an improved understanding of the role of vegetated coastal habitats in sequestering CO2
Recent research has highlighted the valuable role that coastal and marine ecosystems play in sequestering carbon dioxide (CO(2)). The carbon (C) sequestered in vegetated coastal ecosystems,
Impacts of ocean acidification on marine organisms: quantifying sensitivities and interaction with warming
The most comprehensive meta-analysis to date by synthesizing the results of 228 studies examining biological responses to ocean acidification reveals decreased survival, calcification, growth, development and abundance in response to acidification, and suggests that other factors, such as nutritional status or source population, could cause substantial variation in organisms' responses.
Thresholds of hypoxia for marine biodiversity
A broad comparative analysis showed that hypoxia thresholds vary greatly across marine benthic organisms and that the conventional definition of 2 mg O2/liter to designate waters as hypoxic is below the empirical sublethal and lethal O2 thresholds for half of the species tested.
A Global Crisis for Seagrass Ecosystems
ABSTRACT Seagrasses, marine flowering plants, have a long evolutionary history but are now challenged with rapid environmental changes as a result of coastal human population pressures. Seagrasses

Seagrasses cover about 0.1–0.2% of the global ocean, and develop highly productive ecosystems which fulfil a key role in the coastal ecosystem. Widespread seagrass loss results from direct human
Seagrass nutrient content
Carbon:nutrient (N and P) ratios were inversely related to changes in nutrient content, and the rate of change in C:N and C:P ratios with increasing nitrogen or phosphorus content in plant tissues should shift from high to small as nutrient supply meets the plant's demands.
Seagrass ecosystems as a globally significant carbon stock
Seagrass meadows are some of the most productive ecosystems on Earth. An analysis of organic carbon data from just under one thousand seagrass meadows indicates that, globally, these systems could
Plastic debris in the open ocean
Using data from the Malaspina 2010 circumnavigation, regional surveys, and previously published reports, this work shows a worldwide distribution of plastic on the surface of the open ocean, mostly accumulating in the convergence zones of each of the five subtropical gyres with comparable density.
