Oregon Zoo Exhibit Includes Endangered Oregon Spotted frog and its Predator

Sat, 7/19/2008 - 6:32 AM

As the world's frogs vanish at an alarming rate, a few species will appear at the Oregon Zoo Sept. 20 in a temporary exhibit designed to teach the public about the perils faced by amphibian populations everywhere. 

"FROGS!" will run through ZooLights (Dec. 28) and will feature several different species from around the world. It will also explain what's happening to amphibians in the wild and why they are dying out so rapidly.

"As many as 165 amphibian species may be extinct," says Oregon Zoo Director Tony Vecchio. "Without an immediate intervention, one-third to one-half of the world's amphibian species could become extinct in our lifetime. This would constitute an extinction comparable to that of the dinosaurs."

Frogs are considered sentinel animals, which means they are among the first to show the impact of environmental contaminants and climate changes. Their decline serves as a warning sign to other species, including humans.

In addition to pollution and loss of habitat, amphibian populations worldwide are being decimated by chytridiomycosis, an infectious disease caused by the chytrid fungus (Batrachochytrium dendrobatidis). The fungus has rapidly spread from Africa to other parts of the world, including the Pacific Northwest.

The exhibit will offer a look at the Oregon spotted frog, which has captured the attention of conservationists as the most threatened frog in the region.
Not only has it been affected by pollution and the loss of wetlands, but it has become the prey of the American bullfrog, a larger species native to the eastern and midwestern United States that was introduced here in the early 1900s.

This year the Oregon Zoo, in conjunction with the Washington Department of Fish and Wildlife and the Northwest Zoo and Aquarium Alliance, has launched a captive-rearing and release program in an attempt to restore Oregon spotted frog populations and keep the species from extinction.

"FROGS!" will feature examples of both the Oregon spotted frog and the American bullfrog.

Other frogs on display will include the brightly colored poison dart frog, native to Central and South America, which secretes toxins from its skin that are foul-tasting to predators. Three highly toxic species of poison dart frogs were used by indigenous people to poison the tips of blowgun darts.

The Vietnamese mossy frog is covered with bumps, spines and tubercles, helping it blend in with moss and lichen to avoid predators. This species'
camouflage has been called the most elaborate in the animal kingdom.

White's tree frog, native to Australia, was one of the first amphibian species documented in the discovery of the deadly chytrid fungus. In dry conditions, it can surround itself with a cocoon of dead skin and mucus and burrow to keep moist.

The exhibit is in conjunction with the Association of Zoo and Aquariums'
Year of the Frog, which began on Leap Day as a way to engage the public in conservation efforts and draw attention to the amphibian crisis.

The zoo is a service of Metro and is dedicated to its mission to inspire the community to create a better future for wildlife. Committed to conservation, the zoo is currently working to save endangered California condors, Washington's pygmy rabbits, Oregon silverspot butterflies, Oregon spotted frogs and western pond turtles. Other projects include studies on black rhinos, Asian elephants, polar bears and bats.

The zoo opens at 8 a.m. daily and is located five minutes from downtown Portland, just off Highway 26. The zoo is also accessible by MAX light rail line. Zoo visitors are encouraged to ride MAX or take TriMet bus No. 63.
Visitors who take the bus or MAX receive $1 off zoo admission. Call TriMet Customer Service, 503-238-RIDE (7433), or visit www.trimet.org for fare and route information.

General admission is $9.75 (12-64), seniors $8.25 (65+), children $6.75 (3-11), and infants 2 and under are free; 25 cents of the admission price helps fund regional conservation projects through the zoo's Future for Wildlife program. A parking fee of $2 per car is also required. Additional information is available at www.oregonzoo.org or by calling 503-226-1561.

Irresponsible Board of Management Thu, 11/5/2009 - 9:20 PM — latino boy

Maybe , just maybe The Toronto Zoo Board Is In The Middle Of A Financial Crisis And There Is No Place To Go But To City Council like a wayward son go to Mom and Dad for more money...

Although it was made clear by Shelley Carroll (the City's Budget Chief) that the Toronto Zoo has to behave more financially responsible, perhaps the problem is that there is no place else to go. The $250 Million fund-raising plans are a pipe dream (especially after firing the Zoo Foundation), it is not possible to raise admission prices any longer (or face a significant drop in attendance) and the "junkets" (especially to China for the Giant Pandas) by members of the Zoo Board can not be cut significantly for any reason. In other words, there is no place to go but City Council. What a crock! The Toronto Zoo Board needs a reality check, as it has become clear that they do not understand the problems they are facing. Perhaps the thousands of free Zoo passes given to Councillors on the Zoo Board could be cut to zero, perhaps the Zoo Foundation could be re-instated, and perhaps a citizen's advisory committee could be formed to provide much-needed guidance to the existing members of the Board.

This is Proof positive

that citizens should have more direct say in the budget process. Line item veto by a citizen's budget committee might get the desired cuts we must attain. The citizens of Toronto should stand with one voice that we just won't allow a property tax increase this year.

Ethyl Mercaptan Mon, 11/2/2009 - 2:27 PM — Mercaptan

I would be quite interested in any reference you might have to the presence of ethyl mercaptan in carrion.  Most literature indicates that dimethyl sulfide and methyl mercaptan are the sulfur containing entities involved.  I had also thought that vultures, like many carrion eating and inhabiting species (flies, etc) were attracted to the rather bad smell of the nitrogenous materials (cadaverine, putresceine, etc) produced during decomposition.

Very nice ant exhibit! I wrote a small ant farm post with a reference to your article.

Happy Birthday, Boomer! Sat, 9/12/2009 - 7:26 PM — redapes

You are a great ambassador for your cousins in the wild, Boomer!

Orangutans are critically endangered because of rapid deforestation and the expansion of palm oil plantations.

If nothing is done to protect orangutans, they could be extinct in just a few years!

Your fans can visit the Orangutan Outreach website to make a difference!

Venemous snakes? Fri, 9/11/2009 - 9:18 AM — Kyle Bradley

What is it with people that want to exterminate venemous snakes? If they weren't an integral part of the food chain and ecosystem, they wouldn't be here! Evolution and natural selection has chosen them as survivors! The fact that they are "harmful" to humans is only a result of humans encroaching on their territories and habitats. Be mindful of your surroundings and situation and you can safely live with the so called "harmful" species that we share this planet with!


Local wildlife day Sat, 8/22/2009 - 5:41 PM — Devon eco lodges at Wheatland Farm

Good luck with the event. We have some fabulous wildlife in Devon that's really worth celebrating. We recently had a botanical survey of our small  Devon nature reserve, which recorded more than 180 species in about 3.5 acres. And even more amazing was the depth of local knowledge the visiting naturalists had to share - on everything from obscure moths to lichens.

Sadly, a lack of common sense is the trend Sun, 8/9/2009 - 7:57 PM — eliewriter

What is sad to me is the lack of common sense regarding venomous snakes that seems to becoming more commonplace.

It has become trendy for government agencies to defend venomous snakes, saying they kill rodents, etc., but non-venomous snakes also kill rodents. I have not heard one logical argument as to what a venomous snake contributes to an ecosystem that a non-venomous snake doesn't.

Any non-biased biologist can affirm species extinction has always happened naturally. It's common sense to kill a venomous snake, rather than let it continue breeding and increase the potential for harm.

The unfortunate consequence of naturalists defending venomous snakes is they make them appear so necessary and harmless that both people and agencies--hospitals, for example--do not expect or prepare for snake encounters.

It's doubtful that many hospitals near the snakes stock the expensive antivenin. Governments should help fund snakebite treatment rather than fund snake protection.


Skype Usage Fri, 8/7/2009 - 5:02 PM — Shawn

Very cool and novel way to use Skype. Glad to see that people are thinking outside the box with its collaborative application. If it's not too late, you may want to submit this to Skype as a good use of their software for the Skype in business contest they're running.
