Panamanian golden frogs aren't just cute, little, and yellow. They're also the national symbol of Panama. But they started to disappear about fifteen years ago. What's killing them? Could it be a change in their habitat? What about pollution? Might it be a result of climate change? Follow a team of scientists working to save these frogs and protect frog populations worldwide in this real-life science mystery. "An obvious fit for science classes, this book would also fit nicely into environmental studies, geography, animal study, and the research process. It is an engaging model of the scientific method that is sure to intrigue all young researchers." -- Library Media Connection "This eye-catching, well-written book provides a window into the efforts of a coalition of scientists, wildlife groups, and zoos to decode the mysterious die-off of the Panamanian golden frog, which began in the mid 1990s." -- School Library Journal "Notable for clarity, directness, and simplicity of writing and design alike, this volume, both handsome and fascinating, begins with the hunt for the frogs' killer and ends with the urgent need to create a safe environment for their return to the wild." -- Booklist "Illustrated with excellent photos and microscopic views, this profile of a 'science detective' underscores the vital importance of curiosity, inquiry, and shared communication in scientific work." -- Book Links "This book is a great introduction to the issues of declining amphibians and worldwide loss of biodiversity, but its strength lies in its portrayal of the scientists and their use of the scientific process to solve a scientific mystery." -- Science Books & Films "A sobering glimpse at science in progress." -- Kirkus Reviews Sandra Markle is the author of numerous award-winning books for children.
