Bisphenol A (BPA) is a chemical that is used in a variety of consumer products, such as food storage products and resins that line plastic food and beverage containers. Often, aquatic environments such as rivers and streams become reservoirs for BPA, and fish and turtle habitats are affected. Now, a collaboration of researchers from the University of Missouri, Westminster College, the U.S. Geological Survey and the Saint Louis Zoo have determined that BPA--which mimics estrogen--can alter a turtle's reproductive system and disrupts sexual differentiation. Scientists are concerned findings could indicate harmful effects on environmental and human health.
ANN ARBOR--Efforts to reduce the amount of phosphorus and other nutrients washing off farm fields and into Lake Erie shifted into overdrive after high levels of a bacterial toxin shut down the drinking water supply to more than 400,000 Toledo-area residents last August.
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.
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.
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.
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.
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.
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).
Scientists at the John Innes Centre have discovered why the first buds of spring come increasingly earlier as the climate changes.
The Prigogine Gold Medal is awarded annually to a leading scientist in the field of ecological systems. This year, Bai-Lian (Larry) Li, a professor of ecology at the University of California, Riverside, has been selected to receive it.
