Strengthening the global system of protected areas post-2020: A perspective from the IUCN World Commission on Protected Areas [PDF]

open access: yes, 2020
Protected areas are the cornerstones of biodiversity conservation and have never been more relevant than at the present time when the world is facing both a biodiversity and a climate change crisis.

Climate change and tropical marine ecosystems: A review with an emphasis on coral reefs

open access: yesCuadernos de investigación UNED, 2019
Climate change is usually associated with warming and weather extremes that impact the human environment and terrestrial systems, but it also has profound effects on the ocean, which is probably the most unique, life-supporting feature of planet Earth ...

Geochemistry of reduced inorganic sulfur, reactive iron, and organic carbon in fluvial and marine surface sediment in the Laizhou Bay region, China [PDF]

open access: yes, 2015
Understanding the geochemical cycling of sulfur in sediments is important because it can have implications for both modern environments (e.g., deterioration of water quality) and interpretation of the ancient past (e.g., sediment C/S ratios can be used ...

Zooplankton diel vertical migration enhances carbon export via distinct mechanisms in a warming North Pacific

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract Zooplankton diel vertical migration (DVM) is a crucial marine organism behavior modulating particulate organic carbon (POC) export, yet its dynamic role under climate change remains uncertain. Using a coupled physical–biogeochemical model, we assessed how DVM affects carbon export under future scenarios at two contrasting North Pacific sites ...

Investigating the role that the Southern Ocean biological pump plays in determining global ocean oxygen concentrations and deoxygenation [PDF]

open access: yes, 2013
Global ocean circulation connects marine biogeochemical cycles through the long-range transport of nutrients and oxygen with the Southern Ocean (SO) acting as a water mass crossroads. The biological pump in the SO has been shown to play an important role

The early life history of the clam Macoma balthica in a high CO₂ world [PDF]

open access: yes, 2012
This study investigated the effects of experimentally manipulated seawater carbonate chemistry on several early life history processes of the Baltic tellin (Macoma balthica), a widely distributed bivalve that plays a critical role in the functioning of ...

Altered greenhouse gas emissions in shallow lakes invaded by common carp (Cyprinus carpio)

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract Species invasions are among the most important environmental problems facing freshwater ecosystems this century, contributing to biodiversity loss and changes in ecosystem function. Freshwater lakes are an important component of the global carbon cycle and a key source of atmospheric greenhouse gases, yet the consequences of species invasions ...

Spatial and temporal trends of iron and iron isotope cycling in the Peruvian oxygen minimum zone [PDF]

open access: yes, 2012
Iron (Fe) is a key element in the global ocean’s biogeochemical framework because of its essential role in numerous biological processes. A poorly studied link in the oceanic Fe cycle is the reductive release of Fe from sediments in oxygen depleted ocean
