Researchers in Brunei are studying the migration route and nesting habitat of Olive Ridley Turtles by monitoring the satellite transmitter of a recently-released female turtle.

Earlier this month, a female Olive Ridley Turtle (Lepidochelys olivacea), fitted with a satellite transmitter, was released from Meragang Beach as part of a Southeast Asia Fisheries Development Centre (SEAFDEC) project.

The ability to track this turtle will help locate breeding and nesting grounds, so that conservationists can manage and protect these sensitive sites. By checking daily transmissions, researchers can determine the turtle’s route.

Attaching the transmitter to the turtle’s shell was done with a special glue and then covered with fiberglass, a common method used by researchers to track long-range migration habits of sea turtles.

The extraordinary nesting behavior of the Olive Ridley Turtle

Female Olive Ridley Turtles are responsible for one of the most unusual occurrences found in nature. In a phenomenon known as arribada (”arrival by sea”), it begins when groups of females congregate in the water near nesting sites.

Nairobi, Kenya - A new road is needed in the Kenyan Osupuku Conservancy. And strong stone is needed for the road. A Chinese corporation, Sinohydro, owns a rock quarry, which offers the best stones to build a strong road; a road which wouldn’t need repairs for a long time. However, the rock quarry poses a threat to the aboriginal wildlife of the region.

The Osupuku Conservancy was created in 2008 as a means of protecting elephants. The conservancy is a corridor that links Amboseli to Kenya’s Chyullu Hills and Tsavo National Parks and is a thoroughfare for elephant migration. However, elephants may discontinue using the conservancy if the rock quarry is permitted to continue.

“We are not against the building of the road, but [we are against] the area from which the material for the road construction is to be gotten from,” said African Wildlife Foundation (AWF)’s Fiesta Warinwa. The quarry is controversial for multiple reasons, but first and foremost may be the use of explosives in creating the quarry.

Results recently published in the journal Global Change Biology show a population drop of 60% in worldwide caribou and reindeer numbers over the last three decades.

The dramatic decline in population is likely due to climate change and increased industrial development in boreal forests around the world.

Seen above, the sea turtle known as Wawa Bear traveled 4471 miles and had her entire route tracked successfully. At 1315 pounds, it should not be hard to imagine where the name “bear” comes from. Wawa Bear is, in fact, the largest sea turtle ever captured in Nova Scotian waters.

In fact, it is estimated that for every acre of rainforest that is cut down, 50 acres of forest is revitalized areas that were once farmed, logged, or destroyed by natural disasters.

As a passionate enemy of suburban sprawl, I listened intently to an interview this morning on NPR with Brookings Institution demographer William Frey in which he notes that housing prices are falling faster in the areas outside cities. Is this a permanent correction that is making “exurbs” less desirable overall? And how are gas prices influencing this loss of home value? Mr. Frey was cautious in his answer, saying “the jury is still out” and that Americans have a history of moving outward from cities in order to buy more housing for less, seeing long commutes as an acceptable trade off.

However, it doesn’t take a genius to see that, when a commute costs more than one is saving on housing, while sucking up hours of one’s valuable time, (and as the saying goes, “They aren’t making more of that”) why would one buy a home in the far suburbs? Why, indeed?

Sperling’s Best Places did a survey two years ago when gas prices were at $2.90 a gallon. The following were the most expensive cities in which to commute and listed the average annual commuting cost:

City Annual Commuting Cost (2006)

1. Atlanta $5,772
2. Birmingham, Ala. $5,464
3. Orlando, Fla. $5,404
4. Jacksonville, Fla. $5,360
5. Pensacola, Fla. $5,173

So, if gas prices reach $6.00, Atlanta’s commuting cost would be over $10,000 per year. Yikes.

Climate change is altering Pacific gray whales’ migration patterns. According to Rob Davis, “The whales’ fall migration south past San Diego is peaking five days later than it once did. Once they get to Baja, they’re staying two weeks less than they did in the late 1970s.”
