The lab has just completed a prototype that combines ESRI’s ArcGIS API for Silverlight with the open source Silverlight Augmented Reality Toolkit.
The toolkit allows developers to detect the spatial orientation of a predefined marker. The lab used the orientation information to overlay a map from ESRI’s ArcGIS API for Silverlight. As shown in the video, the map is fully functional even with the perspective distortion.
The demonstration starts with the user browsing a default basemap from ESRI’s resource centerand then performs a search of GeoEye imagery in New Zealand. All imagery is tagged with sensor information such as the capture date, percentage cloud cover and satellite position. In the video, this information is used to order and then offset overlapping imagery. This effect is useful to quickly find imagery based on specific criteria, for example, find the newest imagery with the least amount of cloud cover.
Finally, why not try this demonstration yourself? You will need a computer with a webcam. Clickhere to start the Augmented Reality web application and here to download and print the marker symbol.

Small mammals at risk as world warms

The biodiversity of small mammals in North America may already be close to a "tipping point" causing impacts "up and down the food chain" according to a new study by U.S. scientists. (Left: voile)

Examining fossils excavated from a cave in Northern California, biologists from Stanford University, California uncovered evidence that

small mammal populations were severely depleted during the last episode of global warming around 12,000 years ago.

Many species, say researchers, have never recovered their populations leaving them vulnerable to future rises in temperature.

Deposits in Samwell Cave (upper right) in the foothills of the southern

Cascades mountain range revealed that populations of gophers and voles during the period (the end of the Pleistocene epoch) were on a par with those of deer mice.

But while the deer mice (lower right) population thrived in the warming period and has become one of the most common small mammals in the U.S. today, gophers, voles and other small species' populations

fell away permanently.

The decline in small mammal species during the period contributed to a 30 percent decline in biodiversity, according to the study.

Co-author and professor of biology at Stanford University, Elizabeth Hadly says deer mice are considered a "weedy" species and when they replace other small mammal species, the effects ripple through the ecosystem.

Lead author of the study, Jessica Blois says because they are so common,

it's easy to take small mammals for granted. But they play important ecosystem roles "in soil aeration and seed dispersal and as prey for larger animals." (Left: gopher)

Unlike some larger animals -- mammoths, mastodons and dire wolves -- small mammals never became extinct during the Pleistocene epoch.

But despite their resilience, Blois says small animal species face an uncertain future.

"Even though all of the species survived, small mammal communities as

a whole lost a substantial amount of diversity, which may make them less resilient to future change," she said in a statement. (Right: endangered pika)

The research, which was recently published in the science journal, Nature, underlines the effects climate change could have on all types of biodiversity, not just the "eye-catching species."

"The temperature change over the next hundred years is expected to be

greater than the temperature that most of the mammals that are on the landscape have yet witnessed as a species," Hadly said in a statement. (Left: Dutch rabbit)

"The small-mammal community that we have is really resilient, but it is headed toward a perturbation that is bigger than anything it has seen in the last million years." she added.

The third edition of the U.N.'s Global Biodiversity Outlook (GBO-3) recently

stated biodiversity loss is rising at an unprecedented rate and urged governments to take immediate action to avoid "catastrophic tipping points."

A recent U.N. meeting on biodiversity held in Nairobi, Kenya -- which coincided with the publication of GBO-3 -- has laid the foundations for action to be taken when the U.N. Convention on Biodiversity convene for its 10th conference in Nagoya, Japan in October, according to the International Union for Conservation of Nature (IUCN),

Jane Smart, director of IUCN Biodiversity Conservation Group said in a statement: "There's been overwhelming support in Nairobi for 20 strong, ambitious but realistic targets for the next 10 years, designed to prevent the extinction crisis and restore Earth's ecosystems."

From the Inbox: Explore the Ocean with Me

Dear Friend,

I first traveled to the Galapagos Islands in 1983 on a study-abroad trip for college, and I have lived here most of my adult life.

I was drawn to the islands’ stark beauty and unique wildlife—sea lions, marine iguanas and the famous Darwin’s finches, to name just a few. I have stayed here because of the opportunity to make a difference in the conservation of these and myriad other animals and their remarkable habitats.

As the Andes - Eastern Tropical Pacific Regional Marine Program Coordinator, I believe we’ve made a difference—as have local governments, communities and a growing network of other partners—in helping to protect these islands and the ocean that surrounds them, along with the coastal areas of Costa Rica, Colombia, Ecuador and Panama that collectively make up the Seascape.

This Seascape aims to conserve more than 2 million square kilometers and the diverse sea life—including threatened leatherback sea turtles, hammerhead sharks, humpback whales and many commercially important species—within the Seascape. Taken together, this wildlife underpins the local economies and defines the local communities and cultures of millions of coastal-dwelling people who call this area home, just as my family and I do.

The Eastern Tropical Pacific Seascape is just one of many projects that increasingly offer working examples of Conservation International’s mission to empower societies to responsibly and sustainably care for nature for the well-being of humanity.

CI and our partners are striving to expand this work and establish four more Seascapes in Brazil, the Central Pacific, Hawaii and the Western Indian Ocean.

Over the next few weeks, our marine team will take you to the front lines of our work – the coasts, the mangrove forests, the open oceans and the coral reefs.

We will visit the spectacular animals that call the oceans home, explore the important benefits that oceans provide to humanity and examine win-win solutions we’re putting into practice to protect those benefits for generations to come.

Thank you for your continued support.

Sincerely,

Scott Henderson
Andes - Eastern Tropical Pacific Regional Marine Program Coordinator
