The fox came back. But not quite the very next day…

Sierra Nevada Red Fox

Sierra Nevada red fox caught on remote camera in Yosemite National Park

The Sierra Nevada red fox is one of the rarest mammals in North America: until recently they hadn’t been spotted in Yosemite National Park for nearly 100 years. They used to be plentiful in the region, but hunting and habitat destruction from logging, livestock grazing, and off-road vehicles have cut their population to fewer than 50 individuals. Climate change is also affecting the foxes’ habitat, forcing them farther up into the mountains. Fewer Sierra Nevada foxes mean that their genetic diversity is limited, which may have grave implications for the species’ survival.

The Yosemite Conservancy is funding a study to determine the occurrence and distribution of rare carnivores in the park. Good news: Biologists have announced that in the past two months there have been two sightings of one (or two) Sierra Nevada foxes in the northern part of Yosemite, caught on remote cameras in the back country. (It’s unclear if the cameras have caught two images of the same Sierra Nevada fox or one image each of different foxes.)

Near the remote cameras, the park’s biologists have set up hair snare stations in an effort to collect hair samples for genetic analysis. A few Sierra Nevada foxes have been seen north of the park, in the Sonora Pass area, over the past few years, and the biologists want to determine if the fox(es) spotted in Yosemite are related genetically to the Sonora Pass foxes. The more the merrier: more foxes = a more diverse gene pool, which may help the Sierra Nevada red fox stage a real comeback.

Early Warbler System

Supercell storm

Apparently birds—in this case, golden-winged warblers—know big storms are headed their way several days before the storms actually arrive. According to a story in the UC Berkeley News Center, a research team led by a UC Berkeley ecologist discovered that warblers in the mountains of eastern Tennessee fled their breeding grounds one to two days ahead of the arrival of devastating supercell storms in April 2014. The storms spawned dozens of tornados, killing more than 30 people.

The discovery was accidental: the golden-winged warblers were part of a migration study, and were being tracked by miniature GPS devices attached to their backs. The scientists knew that birds can change their route to avoid weather disruptions during regular migration, but had no idea they’d leave their established breeding territory to avoid severe weather.

The birds fled the scene when the storm was about 300 miles away—even before the air pressure dropped and the winds picked up. And they went some distance: according to the study, the warblers flew over 900 miles as they avoided the weather system. They returned to their breeding grounds just after the storm passed.

Salmon have a rough commute. When they go upstream to spawn in the fall, they face a lot of obstacles along the way, including dams. Lots of dams. In the spring, the juvenile salmon make their way back downstream to the ocean, and they, too, have to navigate the dams.

Many dams have fish ladders that help the fish safely make their journey upstream. But getting downstream is a whole different story. Hydroelectric dams, in particular, present a huge challenge. Between strong currents, rapidly changing water pressure, and huge turbines, the young fish can get stunned, injured, or killed.  Although there are various methods in place to keep the fish away from the turbines, many still end up going through the the engines.

As many hydroelectric dams built during and before the 1970s are currently due for relicensing, their environmental impact is being assessed. And one of the key indicators of a dam’s environmental impact is how well fish fare when they encounter one. Collecting precise data was nearly impossible until the invention of a nifty device.

Using TV Whitespaces to Monitor Endangered Species

The Zoological Society of London mines the gap.

I am always impressed with the imaginative ways the Zoological Society of London uses technology to try to protect and conserve endangered species. Here’s their latest brainstorm, as described on the ZSL website:

“ZSL and Google are working together to pilot the use of TV whitespaces (TVWS) – unused channels in the broadcast TV spectrum – at ZSL London Zoo. The trial aims to show how TVWS can be used to provide wireless connectivity over a large area and in non-line-of-sight scenarios. This exciting technology has huge potential to deliver fast internet to ZSL’s remote conservation sites and help monitor wildlife globally.

The pilot consists of cameras and TVWS radios installed at the otter, meerkat and Galapagos tortoise enclosures within the Zoo. Live footage from each enclosure is transmitted using TVWS technology to a base station and then streamed live onto ZSL’s YouTube channel. Members of the public can tune in to the live feeds and watch the animals anytime, anywhere.

To ensure there is no interference with licensed spectrum holders, Google’s spectrum database is being used to identify available whitespace.

This trial is the first step in understanding how ZSL can effectively use TVWS to support its field conservation projects. A particular area of interest is integrating TVWS into ZSL’s Instant Wild remote surveillance system to enhance data transmission range. ”

The YouTube streams started on October 9th, and will be live for two months.

“Save the Whales”


Whalers and their catch, ca. 1913.

Back in the 1970s, a lot of cars sported “Save the Whales” bumper stickers. More than 2 million whales were caught by commercial whalers in the 20th century, and by the middle of the century, many populations were severely depleted. The “Save the Whales” campaign brought millions of people together, resulting in a near-worldwide ban on commercial whaling in 1986. Today, many fewer whales are being taken, but there are still many threats to their survival, including commercial marine traffic.

Big ships run into whales. Inadvertently, of course, but because today’s shipping lanes overlap with whale feeding and migration areas, whales (many of them endangered species) are at great risk of being injured or killed. Obviously, the best way to save the whales is to avoid running into them—and commercial ships now have some free tools that make that possible.

There’s an app for that.

For the past two years, mariners along the U.S. East Coast have been able to download a free iPad and iPhone app that warns them when they enter areas with a high risk of collision with critically endangered North Atlantic right whales. Whale Alert  provides a central source for information about how to navigate around right whales in specific areas, along with the latest data about their whereabouts, all overlaid on NOAA digital charts.

One fish, two fish, right fish, wrong fish

A WWF International Smart Gear Competition to reduce bycatch

Pollock Catch

By some estimates, fishing bycatch—which includes unwanted dolphins, turtles, whales, and birds—snared by gillnets, longlines, and trawlers makes up 40% of the catch today.

The 2014 International Smart Gear Competition seeks innovative, environmentally friendly ways to reduce the amount of fisheries bycatch. The recurring contest is sponsored by the WWF, and has resulted in some really clever solutions (such as LED-equipped nets tuned to various wavelengths that repel specific species) that greatly reduce bycatch, conserving populations of marine mammals, turtles, fish, and other sea creatures.

Open to all, over the last few years the competition has attracted entries from all kinds of people who care about fishing— from gear technologists and fishermen to engineers and chemists. The judges panel includes fisheries experts, gear technologists, fishermen, scientists, researchers, and conservationists.

Deadline for entries for 2014 is August 31, but don’t let that stop you from coming up with new ideas. The contest is a recurring event—and this year’s prizes total $65,000.

Nerds Without Borders Hit the Beach

Newly hatched sea turtles

Newly hatched sea turtles make their way to the ocean.

An item from O’Reilly’s IoT+ Newsletter that caught my eye:

Two million human visitors share the Cape Hatteras National Seashore with endangered turtles. To protect the turtle nests and hatchlings during the hatching period the beaches must be closed—but because it’s difficult to gauge when exactly the baby turtles will hatch, the beach is closed for 6 weeks from the discovery of the nest.

Nerds Without Borders has created nest monitor devices with a microcontroller, accelerometer, thermometer, and communications system inside a ping-pong ball (which, conveniently, looks a lot like a turtle egg).

These sensors more accurately determine when hatching will take place—allowing the beaches to be closed for much shorter periods and giving researchers a heads up when hatching will happen. Duane Benson explains.

(And if you’re wondering where the baby turtles go after they hatch and head out to sea…)
