Competition between species curbs selfishness?
Animals are in constant competition over procreative resources. The interests of the individual and the population are not necessarily one and the same; aggressive insects may fare well in the mating competition, but eventually the proliferation of aggressive genes will weaken the procreative efficiency of the species. view more (2004-12-20)
Higher stress leads to longer life
Eating less may make you healthier: even more reason to start that diet tomorrow. Scientists at the Plymouth Marine Laboratory have found that eating less helps marine animals cope with pollution and other stressful situations, and may even let them live longer. Professor Michael Moore found that triggering a cellular process known as autophagy in... view more... (2004-03-26)
Even seaweeds get sunburned
It is red, it burns and itches: a sunburn on our skin. However, too much sun is not only bad for humans. Many plants react sensitively to an increased dose of ultraviolet radiation, too. Yet they are dependent on sunlight. view more (2008-08-25)
Phytoplankton bounce back from abrupt climate change
Marine sediment cores contain calcareous plankton - single-celled organisms with a coating or shell of calcium carbonate - as fossils. These tiny photosynthesizing plants float in the ocean and move with the currents. view more (2006-02-17)
3,317 and counting (the number of marine species in the Gulf of Maine)
The Gulf of Maine Program of the Census of Marine Life, with the Huntsman Marine Science Center of St. Andrews, New Brunswick, announced today the first count of known marine species in the Gulf of Maine region - more than 50% larger than previous estimates. view more (2006-01-05)
Scientists find new clues to explain Amazonian biodiversity
Ice age climate change and ancient flooding-but not barriers created by rivers-may have promoted the evolution of new insect species in the Amazon region of South America, a new study suggests. view more (2008-07-23)
Female iguanas pay high costs to choose a mate
Picking a mate isn't easy-if you are a female iguana. In a study published in the June 27th issue of the online, open-access journal PLoS ONE, Maren Vitousek of Princeton University and colleagues found that female Galapagos marine iguanas spend a lot of energy picking a mate from a wide range of suitors - energy they could otherwise spend... view more...

New study ranks 'hotspots' of human impact on coastal areas
Coastal marine ecosystems are at risk worldwide as a result of human activities, according to scientists at UC Santa Barbara who have recently published a study in the Journal of Conservation Letters. view more (2009-07-10)
New laboratory to study the oceans and air
Almost two-thirds of the planet is ocean and this has a major impact on our lives. Now the University of East Anglia (UEA) will be home to the world's first facility dedicated to the study of chemical ocean-air interactions which are important in regulating Earth's climate. Examples include ocean uptake of greenhouse gases such as carbon dioxide... view more... (2003-11-21)
North Sea recovers from pollution by antifouling paints
The North Sea has recovered dramatically from the effects of pollution caused by antifouling paints used on boat hulls, according to researchers who claim that proposals for a total ban on the use of tributyl tin (TBT) paints could do more harm than good to the environment. Marine Biologists at Newcastle University say that breeding populations of... view more... (1999-05-28)
Endangered sawfish focus of national collection and recovery efforts
The University of Florida, keeper of the world's shark attack records, is also now overseeing a national records collection for another toothy marine predator: the sawfish. view more (2008-12-02)
Coral Reef Fish Make Their Way Home
Coral reef fish hatchlings dispersed by ocean currents are able to make their way back to their home reefs again to spawn, says a groundbreaking study published today in the journal Science. view more (2007-05-04)
Giant marine reptiles from Sweden
At the end of the Cretaceous, when large-sized theropods, such as Tyrannosaurus rex, roamed terrestrial environments, shallow seas and oceans were invaded by giant marine monitors - the mosasaurs. A recent investigation, presented in a new dissertation at Lund University in Sweden, has revealed that the Swedish mosasaur fauna is one of the most... view more... (2004-01-21)
Decline of world's estuaries and coastal seas
Human activity over the centuries has depleted 90% of marine species, eliminated 65% of seagrass and wetland habitat, degraded water quality 10-1,000 fold, and accelerated species invasions in 12 major estuaries and coastal seas around the world. view more (2006-06-23)
DNA barcodes put to the test
With species around the world disappearing faster than biologists can identify them, many scientists pinned their hopes on DNA barcoding, a recently proposed strategy that treats a short fragment of DNA as a sort of universal product code to identify species. view more (2005-11-29)
Humans
Mounting evidence that human activity is changing the world's oceans in profound and damaging ways is outlined in a new scientific discussion paper released today. view more (2009-07-29)
World interest in Australian fishery impact test
An Australian method for assessing the environmental impact of marine fisheries has caught the eye of fishery management agencies worldwide. view more (2009-10-28)
More species in the tropics because species have been there longer
Why are there more species in the tropics than in the temperate regions of the globe? Many of the world's species live in the tropics (perhaps more than half), but the reason has been debated for more than 100 years. view more (2006-11-02)
Fossil and molecular evidence reveals the history of major marine biodiversity hotspots
The journal "Science" has published in the issue of the 1st of August the results of a detailed research work about the evolution of marine diversity all through the last 50 million years. view more (2008-08-07)
Cold is hot in evolution — UBC researchers debunk belief species evolve faster in tropics
University of British Columbia researchers have discovered that contrary to common belief, species do not evolve faster in warmer climates. view more (2007-03-16)
