The scrappy little mosquitofish has been our champion in the fight against the insect-borne West Nile virus. But for local amphibians, already struggling to survive, it is something else entirely. Scientists have learned this pit bull of ichthyology has an insatiable appetite for tadpoles — including those of the threatened red-legged frog and the endangered Santa Cruz long-toed salamander. That has sent biologists draining ponds in an attempt to evict the fish; in one San Jose pond, the frog returned this spring.

The crowds might have left for the season, but there is still one group of visitors that flocks to southern New Jersey as the weather gets colder: ducks. The banding of ducks - placing metal tags on their feet and keeping track of their species, their ages and their sex - is a useful tool to get a sense of what duck populations are like in southern New Jersey. But once migrating ducks start making this area their home, that task becomes much more difficult.

Below America's waters lies a junkyard. Every year, thousands of boats, barges and ships sink or are abandoned in the U.S., having been rendered unusable due to accidents, weather damage, age or an owner's financial duress, and the vast majority of them are never recovered."You go to any harbor or shoreline in the country and you'll find derelict and abandoned vessels," said Doug Helton, acting director of the National Oceanic and Atmospheric Administration (NOAA) Marine Debris Program.

As bears spend more time near cities, the animals gain weight, get pregnant at a younger age and die young, violent deaths. A new study of black bears near the populated Lake Tahoe, Nev., area found an alarming percentage are hit by cars. "Urban areas are becoming the ultimate bear traps," said Wildlife Conservation Society researcher Jon Beckmann, the study's lead author. "Because of an abundant food source — namely garbage — bears are being drawn in from backcountry areas into urbanized landscapes where they meet their demise."

The Soil Association has urged the government to ban pesticides linked to honeybee deaths around the world. The chemicals are widely used in UK agriculture but have been banned as a precaution in four other European countries. Last week the Italian government issued an immediate suspension after it accepted that the pesticides were implicated in killing honeybees, joining France, Germany and Slovenia.

Beyond the damage it is expected to inflict upon sensitive marine ecosystems, ocean acidification may also allow sound to travel farther underwater, creating a louder deep sea din. The change may have implications for marine mammal communication, and for military, commercial and scientific applications.
