Lake Erie's Dead Zones Greatly Affect Fish Distributions, Catch Rates

New research shows that Lake Erie's dead zones are actually quite active, greatly affecting fish distributions, catch rates and the effectiveness of fishing gear.

Fishing May Worsen Population Collapses in Species of Forage Fish

A new study shows for the first time that fishing likely worsens population collapses in species of forage fish, including herring, anchovies and sardines. Some of the largest fisheries in the world target these species, and these "baitfish" are also a key source of food for larger marine animals, including salmon, tuna, seabirds and whales.

Essential Biodiversity Variables Used to Analyse Gaps Between Policy Objectives and Available Data

Reporting under policy instruments to inform on the trends in biodiversity requires information from a range of different elements of biodiversity, from genetically viable populations to the structure of ecosystems. A new research looks into the Essential Biodiversity Variables as an analytic framework to identify ways in which gaps between biodiversity data and policy reporting needs could be bridged. The study was published in the Journal of Applied Ecology.

Steroids Used on Livestock Affect Sexual Behaviours of Fish

A common growth-promoting hormone used worldwide in the cattle industry has been found to affect the sexual behaviours of fish at a very low concentration in waterways – with potentially serious ecological and evolutionary consequences.

Oxygen Depletion, Hydrogen Sulphide Poisoning of the Ocean May Have Contributed to End-Triassic Mass Extinction

Changes in the biochemical balance of the ocean were a crucial factor in the end-Triassic mass extinction, during which half of all plant, animal and marine life on Earth perished, according to new research involving the University of Southampton.

Computer Game Helps Experience and Explore Complexities of Sustainable Fishing

A new and innovative computer game has been developed that allows players to experience and explore the complexities of sustainable fishing. The game has been used as an interactive stakeholder communication measure by the EC-funded SOCIOEC project, an initiative that was dedicated to investigating the socio economic effects of fisheries management measures of the Common Fisheries Policy (CFP).

Flowers Bloom Earlier When the Sweet Spot for Seeds Comes Earlier Due to Climate Change

Scientists at the John Innes Centre have discovered why the first buds of spring come increasingly earlier as the climate changes.

Ecosystem Services Provided By Different Wetland Types Not Being Considered in Wetland Restoration

Most efforts to protect and restore wetlands mistakenly focus on preserving only total wetland area, with no consideration of ecosystem services provided by different wetland types, according to a new study from the University of Waterloo.

Induced Terrestrial Plant Defences Affect Functioning of Aquatic and Terrestrial Ecosystems

Chemical changes that occur in tree leaves after being attacked by insects and mammals can impact nearby streams, which rely on fallen plant material as a food source, report scientists from the University of Chicago Department of Ecology and Evolution.
