My Research

Kerry Kriger - frogsI am a conservation biologist, and thus the goal of my research is to prevent the extinction of wildlife populations and to ensure that the Earth has healthy ecosystems. Most of my research to date has focused on chytridiomycosis, an emerging infectious disease responsible for mass mortalities, population declines and extinctions of amphibian species on five continents. At least 285 amphibian species worldwide are affected by the disease. In terms of biodiversity loss, chytridiomycosis is the worst disease ever recorded for any group of organisms. Chytridiomycosis is one of a host of emerging infectious diseases that have been rapidly spread throughout the world in recent decades by unintended anthropogenic activities. There currently exists no suitable methods for eradicating the disease from wild populations.

Kerry Kriger - BrazilI investigated the degree to which Australian frog populations living at various altitudes and latitudes (and therefore various temperatures) are affected by the disease. Batrachochytrium dendrobatidis, the fungus that causes chytridiomycosis, has been shown in laboratory experiments to reach its highest pathogenicity at low temperatures, and thus I hypothesized that infection prevalence would be greatest in frogs living at higher altitudes, and at the cooler latitudes further from the equator. Furthermore, as the chytrid fungus cannot survive desiccation, I expected infections to be more prevalent in wetter regions. Although I found that the prevalence and severity of chytrid infections do indeed increase in cool, wet regions, I found no relationship whatsoever between altitude and chytrid levels: the chytrid fungus is widespread at all altitudes in southeast Queensland. This suggests that subtropical frogs are at high risk of disease-related decline.

Other work of mine has included quantifying the effect of chytridiomycosis on the survivorship of Stony Creek Treefrogs Litoria wilcoxii in a highly infected population in Southeast Queensland; documenting the seasonal nature of the disease; and confirming the hypothesis that amphibian species with more aquatic life histories are more prone to chytrid infections. I also investigated means by which methods of diagnosing the disease can be made more accurate and cost efficient.

Kerry Kriger - Marine BiologistThis information has enabled conservation managers in eastern Australia to evaluate the threat of chytridiomycosis to species in the region. It also assists scientists worldwide by allowing them to predict which species and populations are at highest risk of chytridiomycosis-related declines, and to focus monitoring and conservation efforts accordingly. In a broader context, this research provides much needed information on the ecology of emerging infectious diseases, thus strengthening our ability to manage threats to public health.

Prior to becoming involved in amphibian conservation, I conducted research on endangered Hawaiian birds, helped release captive-bred peregrine falcons into the wild in California, examined the biophysical properties of amino acids involved in cystic fibrosis, and evaluated the effectiveness of the cathodic protection along the buried sections of the Trans-Alaska Pipeline, to ensure that there was no corrosion.

"I continue to wish you well with all you're doing for amphibians worldwide. Under your care, SAVE THE FROGS! becomes more amazing by the day! Thank you.

Save The Frogs Day

Save The Frogs Day 2011I conceived and coordinate Save The Frogs Day, which I feel strongly is the single most effective tool we have for spreading the word about the plight of amphibians and inspiring people to protect them. The 5th Annual Save The Frogs Day (April 27, 2013) was the largest day of amphibian education and conservation action in the planet's history, with over 270 known events in 30+ countries, directly reaching over 17,000 participants. Save The Frogs Day has been legally recognized in the States of Virginia and North Carolina, and South Carolina by Governors Tim Kaine, Bev Perdue and Nikki Haley; the District of Columbia by Mayor Adrian Fenty; the City of Vancouver, BC by Mayor Gregor Robertson; and in Santa Cruz, CA by Mayor Mike Rotkin, who attended my presentation at Monarch Community School on the 2nd Annual Save The Frogs Day. Thanks to Nature's Path Envirokidz Cereal for their generous financial support of Save The Frogs Day.

"Congratulations because Save The Frogs Day has become an icon in conservation around the world!!! Thanks for such inspiring work!!!"
-- Dr. Nicolas Urbina-Cardona, Faculty of Environmental and Rural Studies, Javeriana University, Bogota, Colombia

"Dear Kerry, I read about some of the worldwide events on behalf of the little guys...I want to say congrats on such fantastic and focused work toward such important and humane goals for frogs. I continue to wish you all the best."
-- Joseph Sporn, New York

Why Frogs?

One of the reasons I felt the need to start SAVE THE FROGS! is because people always asked me "why frogs?". Actually, I still get the question all the time. If people don't know frogs are cool, in trouble, and worth saving, then it will be difficult to save the frogs. This is why SAVE THE FROGS! always has a large focus on environmental education. When people ask me the question, there are two things they may be asking: (1) "What's happening to the frogs and why should we care?", for which I've created this Why Frogs page; and (2) "Why did you get interested in frogs?". Here's my answer to question #2, written in response to a young fan...

Q: "Dear Mr. Kriger, I love your website. I am positively the biggest frog lover in the world. I am eleven years old and I live in colorado. My name is Kathryn and my room is totally decorated in frog stuff. Well the reason why I am e-mailing you is because I wanted to ask you, how did your love for frogs start and why do you believe that frogs should be saved? Well it would be great if you could answer me back. Thanks. Kathryn B."

A: I actually never had any fascination with frogs when I was growing up. While in the rainforests of Costa Rica's Osa Peninsula when I was 20 though, I saw a treefrog calling from the side of a tree, and I was struck by how amazing and primitive it was. I felt pretty lucky to see something so incredible. A few years later I had to decide what to study for my Ph.D. research. Since I like hanging out at streams, I decided I should work with animals that live along streams. While deciding between various groups of stream-dwelling animals, I learnt that frogs were rapidly disappearing, so they became the obvious choice for my Ph.D. research. Spending four years hanging out with frogs in the rainforest definitely confirmed my belief that frogs are the coolest animals! It would be a terrible loss if we lost the sense of connection with nature we feel when we are around frogs. Since the frogs have yet to be saved, I don't see much reason to switch the focus of my environmental efforts.

"Hello Kerry, Thank you for all that you do. I admire and applaud you and all the other tireless advocates who spends so much of their time and resources helping our creatures. I appreciate your very hard work and dedication. Sincerely, Mindy Meadows"

What they're saying

"Yay, Kerry!!!!! This is such a great educational website. We are proud to support it and help this most critical cause of our time continue to gain momentum. Thank you for your indomitable spirit and hard work."
-- Kay Cookerly

"Dear Kerry, It is you who deserves the thanks for your vision, hard work and self-sacrificing. You're an inspiration not only to us old folks, but to the coming generations. There's no doubt that you will long be remembered and what a legacy!
Hugs and Ribbits." -- Joy Cogan

"He just had them all totally engaged. He had great slides and a great rapport with these kids, talking about why frogs matter. I know that he's a serious scientist, but I'm equally impressed with people when they can keep an auditorium full of kids engaged."
--Santa Cruz Mayor Mike Rotkin on my Save The Frogs Day presentation at Monarch Community School, April 30th, 2010

"Kerry, working with STF! has changed my life...thank you for this opportunity."
--Michael Starkey, SAVE THE FROGS! Advisory Committee Member

"Last year the school where I teach changed our state history when students in my after school club convinced politicians in Sacramento to declare a state amphibian, which was signed into law by Governor Jerry Brown. It was a year long interdisciplinary project involving science, civics, and language arts. After initially deciding to embark on the project, we received immeasurable help when we contacted Dr. Kerry Kriger, a scientist in Berkeley who specializes in amphibians. Our students had never responded so enthusiastically to a presenter. After he spoke that day of his Indiana Jones-like travels through far off frog habitats in continents around the globe and of his many unique encounters with a variety of fascinating amphibians, two boys approached me and said they too want to be frog scientists when they grow up. This came to me as a particular blessing as I teach in a very rural and remote desert community of predominantly farm worker children who, despite all their teachers say and do, often lack the confidence to voice high aspirations, especially without any prompting."
— Virginia Haddad, Sea View Elementary School, Salton City, CA

"Hi Kerry, Happy New Year to you and thank you very much for all you are doing on behalf of frogs. Everyone loves to stand around wringing their hands over the worldwide decline in amphibians, but few actually do anything. It's refreshing to see someone with the knowledge, commitment and the courage to actually DO SOMETHING about this global crisis. Everyone, including me, is indebted to you!"
--George Bates, DVM; Professor, Wilson College, Chambersburg, PA

"Keep up the amazing work Kerry! I have nothing but respect for what your doing!"
--The Snake Man, Matt Ellerbeck

-- Liz Koegel, London, UK

"I have tremendous admiration for your extraordinary effort, determination and success."
-- John Poynton, Professor & Amphibian Biologist, United Kingdom

"Dear Dr. Kriger, Thank you for your important work to save our frogs! As a school librarian at an elementary school, I was delighted to come across your website, and held a schoolwide art contest patterned after yours. The contest truly raised awareness among my students, and I know some of these kids will now have a greater respect for frogs and animals as a result."
-- Kelly Posey, San Marcos, TX

"Congratulations to you Kerry. Look at all one man can do when he sets his sights on an important mission. Hopefully frogs will go viral, and start a huge revolution on this earth to take care of it and all life."
-- Margot Fass, Artist, New York City

"Hi Kerry, your website and your work look outstanding.  You are the hero for many in this area."
--Annette Tanner, Western Canada Wilderness Committee

"Thank you for your outstanding efforts. I appreciate it and future generations and frogs do too."

-- Liz York, New York City

"Dr. Kerry Kriger is an American HERO! Thank you for your passionate presentation and your ongoing work to stop the insanity you clearly help us understand."
-- 888gulfstream (YouTube user ID)

"Dear Dr. Kriger, I have visited the Save The Frogs website too many times to count, and have used several of your own publications in my research paper. A lot of the work you are doing has become such an inspiration to me in my own work, both research and promoting amphibian conservation among my peers. I found out that my school is still doing frog dissections and I am drafting a letter against it to the department head and hoping that goes well."

"Dear Dr. Kriger, My name is Jenna and I am 10 years old. I want to be a herpetologist and study frogs when I grow up. Thank you for making SaveTheFrogs.com, it's awesome. I have loved frogs pretty much my whole life so I am extremely glad other people care about frogs too. I am really jealous you got to go to so many different places and see different frogs. I hope to join you on an expedition some day. I am so excited to be a member. Yay! I also want to start a Save The Frogs chapter at my middle school this year. If you have any tips please let me know because I have no idea where to start. Frogs forever, Jenna"
-- Jenna Ward, Student Member

"Dr. Kriger, Many thanks for your very well done article on the amphibian population in the February 2012 issue [No. 17] of 'Living Better'. As someone who loves frogs but is a non-scientist in the animal and environmental realm, I truly appreciate the ease with which you write and de-code complicated information for the lay person. Indeed, there appear to be many more reasons than I would have thought that are causing the seemingly serious de-population of many amphibian species. Thanks for taking the time to help make this topic relevant. If you're ever in Richmond, Virginia giving a lecture, please let me know. I'll be sure to attend. In good health, Brian J. Anderson, M.S."

"You are a very talented man, and I am impressed with your many academic accomplishments, your many interesting hobbies like playing the bamboo flute, climbing mountains, and designing web sites, plus your many academic publications.  I am glad to be part of this very unusual choice of a public charity, and I am learning alot from your newsletters.  Thank you for all of your efforts to save amphibians.

"Dear Kerry Kriger,
Originally I wanted to thank you for all you have done to save amphibians, but in writing this letter I realized that you have impacted my life on a much more personal level. When I was 7 my favorite animals were frogs. I had pictures of frogs pasted all over my room and my favorite thing to do was to go to my grandparents' house and look for rough skinned newts on a hiking trail there. That's why when I heard about SAVE THE FROGS! and the problems amphibians were facing I was really upset. I cried for hours, cursing big companies for being so careless about the environment. After that day I knew exactly what I wanted to be when I grew up. I set a life goal to become a herpetologist. In the following years I did everything I could to help my favorite animal. With my family's support I started a lemonade stand to raise money that I would donate to your website. I also made posters to put up around my school, started a club and spread the word about the problems frogs faced, to everyone I met. By the time I was 9, I had donated over $400 from fundraisers, selling lemonade and giving away my own money, yet I was not satisfied. I still wanted to be a herpetologist, but I knew it would not be easy. That's why, along with the occasional donation, I started to focus on school, striving for good grades to prepare for high school. Nowadays, I'm still a normal teen. I hang out with friends, and play video games and sports, but unlike most 7th graders, I have a life goal: a dream that inspires me to try my hardest in school and help the environment. I dream that no matter where life takes me, it has taught me to work hard and never give up. A dream you gave me. Which is why, besides all you do to save the frogs, I want to thank you making me a better person, and if all goes well, maybe someday, I will join you as a real herpetologist.
Adam Clayton, Oregon"

"Hi Dr. Kerry,
Keep up the great work building ponds! I love the video of all the kids at the school building the pond - really cool! I saw that you were building Santa Cruz long-toed salamander ponds, I would love to see them sometime. I appreciate what you do and am in awe of your energy. ;) Keep in touch."

-- Christina Cunningham, United Kingdom

"Dear Dr. Kerry Kriger, I myself am an 11 year-old who has a dream of becoming a future herpetologist. Ever since I was little, I have had a fascination for frogs and other amphibians. You not only have inspired me as a fellow scientist to try to become a herpetologist, but also have made me more aware of the animals and the world around me. I hope later your inspiration will pay off! Thank you, once again, to the man who has inspired me to do what I will later do and to what I have done."
--Brianna Dewey

"Dr. Kriger, Thank you for all of your love and passion for amphibian conservation. My students felt empowered after your skype session and have been talking about how they can be more conscious of amphibian conservation as well as other environmental issues. SAVE THE FROGS! is a very unique organization. The dedication that you and your staff make to get information out to people inspires others to get involved. I feel like I stumbled on an educational gold mine. Please accept my school's modest donation from the proceeds of our "freaky frog" calendars. They were a labor of love! Regards, Kara"

--Kay Cookerly

"Dear Dr. Kerry Kriger, Thanks for your hard work saving frogs around the world, I have been following all your actions and I'm very impressed and happy to know there are people preserving these jewels of nature. I'm from Costa Rica and have my own Frog Garden with around 34 different Frog species. I am currently running a frog watching tour to see these wonderful creatures in the wild. Also we had made few educational projects with children from local schools and people from the neighborhood, to inculcate them with a love for nature and make them preserve nature. You can see more info in www.frogsanctuary.com or in www.arenaloasis.com. I am now wondering if there is anything we can do to bring SAVE THE FROGS! to Costa Rica. We need a lot of help to educate children in our country. Best regards, José Andrés Rojas Bonilla"

"Hi Mr. Kriger, I want to personally express my appreciation to you for the good job you are doing to save humanity and more importantly our environment. I have now an in-depth knowledge about our activities that have the potential to affect other lives around us. I would be glad to play any advocacy role in championing the cause of safe environmental practices that will not endanger any species on planet earth. It takes people like you and your partners to awaken in us the very existence of our being and the crucial role other species play to make our lives worth living. Although I have not yet registered as a member of the Ghana branch of Save The Frogs International, I can proudly say I am a member already! I wish you safe journey every where you go. Once again, congratulations. Sincerely yours."

Kerry Kayak"I am very pleased to announce that the prolonged process of awarding the inaugural Scott Piper Best Student Publication for 2007 Award has finally been completed. I looked at all of the papers before opening the file with the rankings. They are all very good, but the one on Latitudinal Variation in Chytrid infection seemed to me to deserve special mention. It addresses an important question, reports a huge amount of field work conducted and analysed very rigorously, and its findings make an important contribution to conservation biology, with messages for amphibian workers elsewhere as well. I note that three of the four assessors also ranked that paper first, while the fourth ranked it second, so I think Kriger, Pereoglou & Hero 2007 emerges as the winning paper. We can, therefore, announce that the winner is Kerry Kriger for his paper Latitudinal variation in the prevalence and intensity of chytrid (Batrachochytridium dendrobatidis) infection in eastern Australia. Finally, congratulations to all for such excellence in science."
