How Many Species Are There on Earth and in the Ocean?
It is shown that the higher taxonomic classification of species follows a consistent and predictable pattern from which the total number of species in a taxonomic group can be estimated, and when applied to all domains of life, it predicts ∼8.7 million eukaryotic species globally.
Rapid worldwide depletion of predatory fish communities
The analysis suggests that management based on recent data alone may be misleading, and provides minimum estimates for unexploited communities, which could serve as the 'missing baseline' needed for future restoration efforts.
Rebuilding Global Fisheries
Current trends in world fisheries are analyzed from a fisheries and conservation perspective, finding that 63% of assessed fish stocks worldwide still require rebuilding, and even lower exploitation rates are needed to reverse the collapse of vulnerable species.

Open-area models highlight priority areas for shark conservation, and the need to consider effort reallocation and site selection if marine reserves are to benefit multiple threatened species.

It is shown that genotypic diversity can replace the role of species diversity in a species-poor coastal ecosystem, and it may buffer against extreme climatic events, and the importance of maintaining genetic as well as species diversity to enhance ecosystem resilience in a world of increasing uncertainty.
Impacts of Biodiversity Loss on Ocean Ecosystem Services
Human-dominated marine ecosystems are experiencing accelerating loss of populations and species, with largely unknown consequences. We analyzed local experiments, long-term regional time series, and…
Predicting ecological consequences of marine top predator declines.
Global patterns and predictors of marine biodiversity across taxa
Two major patterns emerged: coastal species showed maximum diversity in the Western Pacific, whereas oceanic groups consistently peaked across broad mid-latitudinal bands in all oceans, and changes in ocean temperature, in conjunction with other human impacts, may ultimately rearrange the global distribution of life in the ocean.
Response to Comments on "Impacts of Biodiversity Loss on Ocean Ecosystem Services"
It is shown that globally declining fisheries catch trends cannot be explained by random processes and are consistent with declining stock abundance trends, and may provide a benchmark against which to assess the effectiveness of conservation measures.
Global phytoplankton decline over the past century
It is concluded that global phytoplankton concentration has declined over the past century; this decline will need to be considered in future studies of marine ecosystems, geochemical cycling, ocean circulation and fisheries.
