Invasive species date back thousands of years
(10/13/2005) Much has been made of the economic impacts of recent biological invasions, but what are the implications of invasions in deep time? Luiz Rocha leads geneticists who time travel through ocean environments. The results of their travels, published online in Molecular Ecology, tell us that during warm, interglacial periods, reef-associated fish (goby genus Gnatholepis), leapt around the horn of Africa into the Atlantic, where their range expanded as the world warmed.


Amazon at record low -- communities isolated, commerce stalled
(10/11/2005) The Amazon River in Peru and parts of Brazil is at its lowest level in 30 years of record keeping. While variable water levels are characteristic of the Amazon river ecosystem, the increasingly extreme fluctuations are of great concern. Low water levels are wreaking havoc on the shipping industry in the region. In Iquitos, a city in the heart of the Peruvian Amazon which is only accessible by plane or boat, ships and barges are having difficulty navigating the river, resulting in serious shipping delays. Local officials in Peru are blaming deforestation of the upper reaches of the Amazon in the Andes for the fall in river levels, although it is likely that larger forces are at least equally important. Warmer ocean surface temperatures in the Pacific and low sunspot activity is also affecting weather in the region, while warming in the north Atlantic -- which has helped trigger an unusually strong and destructive hurricane season -- may be preventing the formation of rain clouds over the Amazon Basin.


Extreme drought drops Amazon river to record low levels
(10/7/2005) The Amazon River in Peru and parts of Brazil is at its lowest level in 30 years of record keeping. While variable water levels are characteristic of the Amazon river ecosystem, the increasingly extreme fluctuations are of great concern. Low water levels are wreaking havoc on the shipping industry in the region. In Iquitos, a city in the heart of the Peruvian Amazon which is only accessible by plane or boat, ships and barges are having difficulty navigating the river, resulting in serious shipping delays. Local officials in Peru are blaming deforestation of the upper reaches of the Amazon in the Andes for the fall in river levels, although it is likely that larger forces are at least equally important. Warmer ocean surface temperatures in the Pacific and low sunspot activity is also affecting weather in the region. Brazilian meteorologists have discounted the theory that the severe hurricane season off the US Gulf coast has impacted the availability of moisture in the Amazon.


Great White Shark swims 12,400 miles, shocks scientists
(10/6/2005) A female great white shark tagged in waters off South Africa has completed the first known transoceanic trip for an individual shark, traveling farther than any other shark known, more than 12,400 miles (more than 20,000 kilometers) to the coast of Australia and back again, according to the Bronx Zoo-based Wildlife Conservation Society (WCS) and other organizations in the most recent edition of the journal Science.

New Orleans Aquarium and Zoo faring well since hurricane
(9/2/2005) Audubon Zoo, the Aquarium of the Americas, the Audubon Center for Research of Endangered Species in New Orleans survived Hurricane Katrina relatively unscathed according to reports from operators of the facilities. However, in neighboring Mississippi, the Gulport Marine Life Oceanarium aquarium was totally destroyed.


Global warming may have triggered worst mass extinction
(8/29/2005) A dramatic rise in carbon dioxide 250 million years ago may have caused global temperatures to soar and result in Earth's greatest mass extinction, according to a study published in the September issue of Geology. Global warming, which may have produced temperatures 10 to 30 degrees Celsius higher than today, would have had a significant impact both on oceans, where about 95% of lifeforms became extinct, and on land, where almost 75% of species died out.


Arctic ocean could have ice-free summers by 2100 says new study
(8/24/2005) The current warming trends in the Arctic may shove the Arctic system into a seasonally ice-free state not seen for more than one million years, according to a new report.

Summit explores how fish could feed Africa
(8/22/2005) This week policy makers, industry leaders, and development experts are meeting in Abuja, Nigeria to discuss the future of African fisheries and aquaculture. The fisheries sector, consisting of both inland (freshwater) and marine fisheries, is a vital source of food and income to millions of Africans. Fish production, processing and trade provides employment for more than 10 million, while fish exports from Africa are worth US$ 2.7 billion annually. The following is a description of the summit from Fish for All, an initiative seeking to shape public policy on issues from issues as fish and development, fish and nutrition, health, livelihood, environment, gender, water, river basins and coasts, trade and economic growth.
