Talent-Scope is a monthly news article aimed to be featured each first weekend of the month to give a platform for emerging artists and spotting hidden talents while celebrating even better pictures that deserve more exposure!
----------------------------------------------------------------------------------------------------- A M P H I B I A N . A L A R M Amphibians are declining rapidly; species, genera, and even families are going extinct at an unprecedented rate.
One third to one half of all amphibian species are threatened with extinction, with probably more than 120 already gone in recent years. Habitat loss is the major threat in terms of number of species affected, but the rapid dispersal of amphibian chytrid fungus is of major and urgent concern because of its tendency to drive species to extinction quickly. Scientists believe many more species may go extinct before we are able to act.
F R O G S . M A T T E R Amphibians are a critical part of a healthy natural world. In addition to their intrinsic value as a beautiful part of nature, they offer many benefits to us:
They play an important role in the food web as both predator and prey, maintaining the delicate balance of nature. Where they are disappearing, detrimental effects are already being documented.
Amphibians eat pest insects, benefiting successful agriculture around the world and minimizing the spread of diseases, including malaria.
The skin of amphibians has substances that protect them from some microbes and viruses, offering possible medical cures for a variety of human diseases, including AIDS.
Biologists refer to amphibians as the canary in the coal mine: They are among the first species to be affected by environmental stressors; so when they show declines in the wild, it serves as a warning to other species, including humans.
Amphibians skin is highly permeable, allowing them to drink and breathe. Unfortunately, contaminants also readily enter the body, making amphibians an exceptional indicator of environmental quality. They are particularly sensitive to pollution, making them important sentinels to potential human threats.
Frogs have had a special place in various human cultures for centuries, cherished as agents of life and good luck.
T H E . R E A S O N Amphibians are severely affected by habitat loss, climate change, pollution and pesticides, introduced species, and over-collection for food and pets. While habitat destruction is the major threat, the most immediate cause is a parasitic fungus called amphibian chytrid, a disease that is deadly to hundreds of amphibian species and has quickly spread from Africa across the planet over the past 30-40 years. Global climate change may have exacerbated the problem.
Amphibian chytrid was discovered a decade ago and since then dozens of frog species have gone extinct because of it.
Since the 1930s, African clawed frogs (likely resistant carriers of the fungus) have been shipped around the world by the thousands for human pregnancy tests and lab studies, spreading the disease worldwide. Recently, the food and pet trade may have contributed to the problem as well.
Amphibian chytrid is currently unstoppable and untreatable in the wild, even in protected areas. In the environments where it thrives, the fungus can kill 80 percent of the native amphibians within months, leading to widespread amphibian extinctions.
The amphibian chytrids spread and effects may be exacerbated by climate change.
Warmer temperatures dry the moist areas where amphibians thrive, and cause stress that may lead to greater susceptibility to disease.
After surviving for 360 million years, one-third to one-half of all amphibian species are in danger of becoming extinct potentially the single largest disappearance of a species since the dinosaurs.....
IUCN has called upon zoos and aquaria to help save the amphibians.
The global zoo and aquarium community has taken on this challenge. But implementation costs money and requires political support from all corners of the world. Faced with this challenge, the Amphibian Ark is launching this global Amphibian Ark campaign 2008 The Year of the Frog.
While remaining locally common in many regions, Tiger Salamanders numbers have declined compared with historical levels. One of the largest threats to Tiger Salamander populations is wetland destruction and alteration through aquaculture activities. IUCN status: endangered
The Golden Poison Frog or Golden Dart Frog IUCN status: endangered
The Axolotl is only native to Lake Xochimilco and Lake Chalco in central Mexico. Unfortunately for the axolotl, Lake Chalco no longer exists as it was drained by humans to avoid periodic flooding, and Lake Xochimilco remains a diminished glimpse of its former self, existing mainly as canals. The water temperature in Xochimilco rarely rises above 20°C (68°F), though it may fall to 6 or 7°C (43°F) in the winter, and perhaps lower. The wild population has been put under heavy pressure by the growth of Mexico City IUCN status: critically endangered Poison dart frog IUCN status: vulnerable ---------------------------------------------------------------------------------------- The frogs below are not endangered (yet...?). I picked them to show the beauty of our amphibian co-planet-inhabitants. ---------------------------------------------------------------------------------------- Red-eyed Tree Frog
Beautiful shots of some truly amazing creatures. I'm always so overjoyed whenever I have frogs living in the pond in my backyard. They may not be as pretty as these, but they do an amazing job of keeping down insect populations.

98% of Deviants don't know the difference between "your" and "you're." If you're one of the 2% that wants to punch 'em, put this in your sig.
Daily Literature Deviations is a group that is dedicated to bringing literature to the forefront of the deviantArt community. We attempt to accomplish this by daily featuring Literature artists from around the community that deserve the recognition, but are not getting it.
Each day we will feature 10 deviations from the Literature categories in a News Article. In order to support the artists that we feature, we ask that you the news article as well as check out the individual pieces. We understand that each day you may not be able to check out each and every one of the pieces, everyone has their own things going on. We just ask that you make an attempt to help support the growing Literature community.
When it comes to community spirit, `Rushy is a shining example. From participating in devmeets, to providing positive encouragement to other artists, `Rushy can always be found demonstrating what it really takes to be a true deviant. It's without any hesitation that we are delighted to award the Deviousness Award for July 2009 to `RushyRead More

Faith in Humanity = WE SURVIVED. humanity pulled through. AWESOME
I mean after all who better to talk about the importance that frogs have to our eco system then "Kermit The Frog".
Now okay i grant u he's a Muppet but, i'm sure that if Jim Henson were still alive he'd want to use "Kermit" for something like this.
Plus its a great way to get through to the younger generation and, gain their interest in eco-awareness.

It raised many points about amphibians. Also it made me think that humans are just jealous that amphibians can live on land or in water
