Study shows why Penguins need more protection

‘If we don’t worry about the imminent threats now, it’s probably not worth worrying about the medium-term future’

FRISCO — The world’s penguins could use a little help, a team of  leading conservation biologists said last month, announcing results of a study that systematically assessed global risks to the southern hemisphere sea birds.

While global warming remains a long-term threat, other impacts, primarily related to human activities, are a more clear and present danger, the scientists said, advocating for a more widespread network of marine protected areas to buffer penguins from pollution, tourism and fishing.

“We need to address some of these issues before we think about resilience to climate change,” said Dr. Phil Trathan, head of conservation biology with the British Antarctic Survey. “If we don’t worry about the imminent threats now, it’s probably not worth worrying about the medium-term future,” Trathan said, explaining that penguins living and breeding in southern Africa and South America face the highest risks.

“If you want to create resilient populations, deal with some of the immediate threats, and where the threats are most evident is where penguins inhabit areas close to mankind,” he said. Continue reading

Major Colorado River players announce conservation push

Near critical shortages in California prompt action

FRISCO — With Colorado River water supplies disappearing at a dizzying rate, and with a thirsty — and politically mighty — California parched by drought, the biggest water users at the table said this week they’ll invest $11 million to try and conserve significant amounts of water across all sectors, including including agricultural, municipal and industrial uses.

The Central Arizona Project, Denver Water, The Metropolitan Water District of Southern California and Southern Nevada Water Authority all signed on to what is being presented as a landmark water conservation agreement aimed at demonstrating “the viability of cooperative, voluntary compensated measures,” according to a press release from Denver Water.

Better planning needed to protect ocean resources

Scientists call for ‘zoning’ of coastal waters

By Summit Voice

FRISCO — Piecemeal planning and conservation efforts won’t be enough to preserve valuable ocean resources for future generations, a leading group of environmental and marine scientists said last week, calling on countries around the world to cooperate on zoning coastal waters in an approach that would mirror common land-use planning efforts.

Effective long-term conservation is crucial because about 20 percent of the world’s population  — mostly in developing countries — lives within 60 miles of the coast. Growing populations and worsening climate change impacts ensure that pressures on tropical coastal waters will only grow, they warned. Continue reading

Where have all the blue-footed boobies gone?

Scientists track decline of iconic Galápagos birds

Staff Report

FRISCO — Populations of blue-footed boobies, one of the Galápagos Islands iconic species, have dwindled by a third since the 1960s, mainly because the birds don’t seem to be finding the food they need to breed and raise chicks.

The population decline is so steep that the birds are in danger of dying out, according to a new study published in the journal Avian Conservation and Ecology. The researchers found that sardines have all but disappeared from the birds’ diet, said Wake Forest University biology professor Dave Anderson. Without that primary food source, adult birds are simply choosing not to breed, he said. Continue reading

Staff Report

FRISCO — Tourism and fishing-dependent communities along the East Coast of the U.S. are banding together to voice concerns about seismic airgun testing. According to Oceana, an ocean conservation group, 110 local elected officials and 155 conservation and animal welfare organizations all say the use of airguns to conduct these seismic tests threatens fish populations and profitable fisheries.

Six coastal towns have also passed local resolutions opposing the use of airguns. (Cocoa Beach, FL, Carolina Beach, NC, Caswell Beach, NC, Nags Head, NC, Bradley Beach, NJ and Red Bank, NJ). The loud and constant undersea thumping may decrease the catch rates of certain fisheries, potentially threatening a billion-dollar industry that supports thousands of jobs.

At issue is the use of loud acoustic devices that help energy companies probe for oil beneath the seafloor. Federal officials recently adopted a final proposal that would allow the use of this controversial technology in an area twice the size of California, stretching from Delaware to Florida.

River protection critical for snapping turtles

Staff Report

FRISCO — Conservation of coastal rivers of the northern Gulf of Mexico is vital to the survival of the alligator snapping turtle, including two recently discovered species, University of Florida scientists concluded in a recent study that sheds more light on the taxonomy of the dinosaurs of the turtle world.

The study shows the alligator snapping turtle, the largest freshwater turtle in the Western Hemisphere and previously believed to be one species, is actually three separate species. Continue reading

Court rejects challenge to endangered species deal

Developers and energy companies show no love for rare species

FRISCO — A federal judge last week rejected claims by developers that a 2011 agreement between environmental groups and the federal government will hurt the industry.

At issue is a groundbreaking deal covering more than 700 species that could someday be listed as threatened or endangered. Under the agreement, the U.S. Fish and Wildlife Service said it will make listing decisions on all the species by 2018, and so far, 138 species have been protected or formally proposed for protection.
