A New Butterflyfish— A Rare, Surprise Find— Is Described from the Philippine “Twilight Zone” and Academy Exhibit

Thu, 19 Oct 2017 12:04:00 EST

A newly described species of brown-and-white Philippine butterflyfish—the charismatic Roa rumsfeldi—made a fantastic, 7,000-mile journey before surprising scientists with its unknown status. Live specimens collected from 360 feet beneath the ocean’s surface in the Philippine’s Verde Island Passage escaped special notice until a single black fin spine tipped off aquarium biologists back in San Francisco. Deep-diving researchers from the California Academy of Sciences’ Hope for Reefs team—with genetic sequencing help from a parent–son team—share their discovery of a fifth species of Roa this week in ZooKeys.(image)



Illinois Sportfish Recovery a Result of 1972 Clean Water Act, Scientists Report

Wed, 18 Oct 2017 12:35:00 EST

Populations of largemouth bass, bluegill, catfish and other sportfish are at the highest levels recorded in more than a century in the Illinois River, according to a new report. Their dramatic recovery, from populations close to zero near Chicago throughout much of the 20th century, began just after implementation of the Clean Water Act, the researchers say.(image)

How can a bee fly straight home in the middle of the night after a complicated route through thick vegetation in search of food? For the first time, researchers have been able to show what happens in the brain of the bee.(image)



Beyond Biodiversity: A New Way of Looking at How Species Interconnect

Thu, 12 Oct 2017 09:11:00 EST

In 1966, an ecologist at the University of Washington named Robert Paine removed all the ochre starfish from a short stretch of Pacific shoreline on Washington’s Olympic Peninsula. The absence of the predator had a dramatic effect on its ecosystem. In less than a year, a diverse tidal environment collapsed into a monoculture of mussels because the starfish was no longer around to eat them.(image)

Getting caught in fishing nets is a major cause of death for the increasingly endangered New Zealand sea lion, according to new research from the University of Otago, Massey University and the University of Toronto.(image)



Best way to save the caribou? Look at white-tailed deer and moose

Wed, 11 Oct 2017 08:26:00 EST

The most effective way to save North America’s dwindling caribou herds is to keep numbers of invading prey animals—like deer and moose—low, according to a new UAlberta research study.“Prey like moose and deer are expanding in numbers and range because of logging and climate change,” said Robert Serrouya, a postdoctoral fellow in biological sciences professor Stan Boutin’s lab.(image)
