Rapid Global Expansion of Invertebrate Fisheries: Trends, Drivers, and Ecosystem Effects
(2011-03)
Background: Worldwide, finfish fisheries are receiving increasing assessment and regulation, slowly leading to more sustainable exploitation and rebuilding. In their wake, invertebrate fisheries are rapidly expanding with ...
Regional-scale effects of eutrophication on ecosystem structure and services of seagrass beds
(2012-09)
Using large-scale field surveys across 12 estuaries in two provinces in Atlantic Canada, we analyzed changes in phytoplankton and benthic macroalgal communities as well as the canopy structure of eelgrass beds and quantified ...
Assessing the Value of Recreational Divers for Censusing Elasmobranchs
(2011-10)
Background: Around the world, researchers are using the observations and experiences of citizens to describe patterns in animal populations. This data is often collected via ongoing sampling or by synthesizing past ...
Large-Scale Absence of Sharks on Reefs in the Greater-Caribbean: A Footprint of Human Pressures
(2010-08)
Background: In recent decades, large pelagic and coastal shark populations have declined dramatically with increased fishing; however, the status of sharks in other systems such as coral reefs remains largely unassessed ...
Long-term change in a meso-predator community in response to prolonged and heterogeneous human impact
(2013-01)
Sharks and rays' abundance can decline considerably with fishing. Community changes, however, are more complex because of species interactions, and variable vulnerability and exposure to fishing. We evaluated long-term ...
The Biodiversity of the Mediterranean Sea: Estimates, Patterns, and Threats
(2010-08)
The Mediterranean Sea is a marine biodiversity hot spot. Here we combined an extensive literature analysis with expert opinions to update publicly available estimates of major taxa in this marine ecosystem and to revise ...
Food-Web Structure of Seagrass Communities across Different Spatial Scales and Human Impacts
(2011-07)
Seagrass beds provide important habitat for a wide range of marine species but are threatened by multiple human impacts in coastal waters. Although seagrass communities have been well-studied in the field, a quantification ...
Overestimating Fish Counts by Non-Instantaneous Visual Censuses: Consequences for Population and Community Descriptions
(2010-07)
Background: Increasingly, underwater visual censuses (UVC) are used to assess fish populations. Several studies have demonstrated the effectiveness of protected areas for increasing fish abundance or provided insight into ...
