Check out my post about a rare skipper and two other butterflies I saw today:
Exposure to endocrine-disrupting chemicals can affect the reproductive system and cause the development of characteristics of the opposite sex, such as eggs in the testes of male fish. Wild- caught fish affected by endocrine-disrupting chemicals have been found in locations across the county. Estrogenic endocrine-disrupting chemicals are derived from a variety of sources from natural estrogens to synthetic pharmaceuticals and agrochemicals that enter the waterways.
As demonstrated in a series of experiments published today in Current Biology, coral trout not only solicit the help of moray eels when they hunt, but also pick their hunting partners wisely. They know when they need help, and quickly learn which eels best provide it. It’s a seemingly simple yet surprisingly sophisticated cognitive trick.
“Prior to our study, chimpanzees an humans were the only species known to possess both of these abilities,” said zoologist Alex Vail of England’s University of Cambridge. “I think the evidence is mounting that fish have more going on in their heads in terms of cognition than they have been given credit for.”
100 years ago this week, the very last pigeon of her kind died in her cage at the Cincinnati Zoo. Her name was Martha, and her passing merits our close attention today.
Mercilessly slaughtered by the tens of millions at breeding colonies in the North and at huge wintertime roosts in the South during the post-Civil War era, passenger pigeons were shipped by trainloads to dinner tables in homes and restaurants across the East. Their population fell from biblical numbers at midcentury to tiny, aimless flocks in 1890. By around 1900 the few birds that remained were all in captivity. The last male died in 1910, leaving Martha as a barren relic of past abundance.
FORT BELKNAP AGENCY, Mont. — In the employee directory of the Fort Belknap Reservation, Bronc Speak Thunder’s title is buffalo wrangler.
In 2012, Mr. Speak Thunder drove a livestock trailer in a convoy from Yellowstone National Park that returned genetically pure bison to tribal land in northeastern Montana for the first time in 140 years. Mr. Speak Thunder, 32, is one of a growing number of younger Native Americans who are helping to restore native animals to tribal lands across the Northern Great Plains, in the Dakotas, Montana and parts of Nebraska.

Scientists now say one of the greatest environmental and economic disasters in the nation’s history is rushing toward a catastrophic conclusion over the next 50 years, so far unabated and largely unnoticed.
The U.S. Environmental Protection Agency plans to take a serious look at the health and environmental risks of atrazine — a dangerous pesticide, commonly found in drinking water, that’s now detected in about 95 percent of our waterways.
Atrazine is a potent endocrine disrupter that causes complete sex reversal in male frogs at concentrations 120 times lower than what the EPA currently allows in our water supply. The toxic chemical also causes an increased risk of birth defects and cancers in humans.
Atrazine’s dangerous risks to wildlife and human health are unacceptable. It’s time for the EPA to ban this chemical.
Please take action now to tell the agency to ban the toxic pesticide atrazine and protect our health and environment.
