Wahaahaha!!!!

Wahahahaha!!! This is an inside joke... only oldies know what he's saying!

A large quantity of nitrogen compounds emitted into the atmosphere by humans through the burning of fossil fuels and the use of nitrogen fertilizers enters the oceans and may lead to the removal of some carbon dioxide from the atmosphere, concluded a team of international scientists.

Evolution is supposed to inch forward over eons, but sometimes, at least in the case of a little fish called the threespine stickleback, the process can go in relative warp-speed reverse, according to a new study. The adaptation coincides with the '60s cleanup of toxic pollution in Seattle's Lake Washington. View the full article

Biologists studying tropical tuna fisheries aimed to establish if the use of drifting fish aggregation devices, a technique employed increasingly for industrial-scale tuna fishery, could act as just such an ecological trap for these species. Examination revealed that the tuna species caught from under the floating objects were less healthy than those taken from free schools. Results suggested that the tuna, in following the artificial rafts, move away from their usual migration routes, which leads them into ecologically less appropriate waters. View the full article

Even in this day and age of exorbitantly colored, ridiculously expensive, inordinately rare corals with over-the-top names like Reverse Radioactive Green Monkey Nipple zooanthids, there's still not much that compares to a school of neons swimming amongst a lush aquatic meadow.

The US Secretary of the Interior has announced that he is accepting the recommendation of U.S. Fish and Wildlife Service Director to list the polar bear as a threatened species under the Endangered Species Act (ESA). The listing is based on the best available science, which shows that loss of sea ice threatens and will likely continue to threaten polar bear habitat. This loss of habitat puts polar bears at risk of becoming endangered in the foreseeable future, the standard established by the ESA for designating a threatened species. View the full article

You might think that stocking the Great Lakes with things like trout and salmon would be good for the herring gull. The birds often eat from the water, so it would be natural to assume that more fish would mean better dining. But a new report published in the journal Ecology says that restoring fish has not been good for the birds. View the full article

It's a tough job, but somebody, or at least some dogs, have to do it. In the Cerrado region of Brazil, four dogs trained to detect animal feces by scent are helping researchers monitor rare and threatened wildlife such as jaguar, tapir, giant anteater and maned wolf in and around Emas National Park, a protected area with the largest concentration of threatened species in Brazil.

A Swiss marine biologist and an Australian quantum physicist have found that a species of shrimp from the Great Barrier Reef, Australia, can see a world invisible to all other animals. Mantis shrimp not only have the ability to see colors from the ultraviolet through to the infrared, but have optimal polarization vision -- a first for any animal and a capability that humanity has only achieved in the last decade using fast computer technology.

Scientists in Louisiana are reporting development and successful testing of a new cost-effective system to kill unwanted plants and animals that hitch a ride to the United States in the ballast water of merchant ships. These so-called "invasive species," such as the notorious zebra mussel, devastate native organisms and infrastructure and cost taxpayers billions of dollars annually. View the full article

Over a decade of work and contributions by more than 200 leading conservation scientists have produced a first-ever comprehensive map and database of the diversity of life in the world's freshwater ecosystems. Freshwater Ecoregions of the World divides the world's freshwater systems into 426 distinct conservation units, many of which are rich in species but under increasing pressure from human population growth, rising water use, and habitat alteration.

People diet to look more attractive. Fish diet to avoid being beaten up, thrown out of their social group and getting eaten as a result. Researchers have discovered that subordinate gobis deliberately diet to avoid posing a challenge to their larger rivals by consistently remaining 5-10% smaller. Once a subordinate fish grows to within 5-10% of its larger rival, it provokes a fight which usually ends in the smaller goby being expelled from the group. View the full article

Reducing the spread of some invasive species into our lakes could be as simple as asking boaters and fishers to dry out their equipment, says one biology professor studying invasive species in Lake Ontario. When anchor rope, fishing line and the boats themselves are thoroughly dried, the invasive species and their eggs will die, rather than spreading to another location, she explains. "It's such a simple thing for the general public to do, and yet it could make a big difference in the way that our lake ecosystems function." View the full article

In the Ebro River delta, the fishing of elver (an eel, Anguilla anguilla) leads to the accidental capture of other fish species, with the capture of one ton of elver possibly resulting in the capture of up to 8.2 tons of accompanying species. Researchers who have assessed the effects of this method of fishing and identified the most fragile species, propose improvements in current methodologies. View the full article
