Saving Sea Turtles: Extraordinary Stories from the Battle Against Extinction [Hardcover]
by James R. Spotila
240 pages, $24.95
ISBN-13: 978-0801899072
Nonfiction

In 2003, Disney released Finding Nemo, a forlorn tale which chronicles the haphazard journey of a Clownfish named Marlin as he navigates the Great Barrier Reef to locate his missing son, Nemo. In the opening scenes of that movie, Nemo excitedly asks his dad if he has ever met a shark with an important follow-on question: "How old are sea turtles?" Marlin, perhaps a little too annoyed while contemplating his son's first day of school replies, "Well, if I ever meet a sea turtle I'll ask him, right after I'm done talking to the shark." Fortunately, this said tale has a happy ending-Marlin is reunited with his son and informs him that some sea turtles live to be 150 years old.

Such is the mythos of animated cartoons where sea creatures are presented as talkative, happy, and engaging. While sea turtles can live to be quite old, the reality is that their numbers are dwindling every year. In his Saving Sea Turtles: Extraordinary Stories from the Battle against Extinction, James Spotila illustrates the issues that directly threaten these amazing aquatic animals.

Dr. James Spotila, a tenured biology professor for Drexel University, has penned a moving work which illustrates the tragedy of many varieties of sea turtles. While he does have a penchant for dropping names and places where his graduate students have studied, the book does not read like a lifeless doctoral dissertation. Quite the contrary, I found his thesis to be stimulating and provocative-throughout I kept asking myself: Is there anything I can do about this? In this collection of stories, the reader learns some amazing truths about the ongoing effort to preserve sea turtles for future generations.

I will never forget a turtle encounter I had while walking along the coastline in North Carolina. Early one morning, my wife and I were enjoying a leisurely stroll when we were flagged down by a determined beach visitor. He showed us the patterns in the sand that were indicative of a sea turtle coming ashore to place her eggs safely in a nest at the head of the beach. Together we called the local conservation society who dispatched a group of volunteers within minutes to cordon off the nest with appropriate notification.

Turtle conservation is necessary to pass along the appreciation of these amazing animals to our children. This book will anger you when you read of the lengths to which some will go to destroy nature. Everyone can play a part in sea turtles conservation-if you enjoy aquatic life, you will love this book.

Mustang Designer

The Good

Labeled a design biography by its author, Ray Wagner, the book reads like a non-fictional historical novel. The story is told from the point of view of the P-51 Mustang's designer, Edgar Schmued. Ray Wagner had access to the designer's personal papers, and it shows. In fact, it was the designer's widow that suggested to Mr. Wagner that he write the book. Being a retired history teacher, Mr. Wagner wrote a wonderful narrative history of this most famous fighter.

This book is a far cry from the typical fighter love fest that I find in bookstores. Text in those other books looks like an afterthought. The focus there is clearly on the pictures. Mr. Wagner, on the other hand, makes it very clear that the star in the book is the story of the fighter.

The scope of the book is large. In about 250 notebook-sized pages, the author tells the story of the events that led to the Mustang being created and looking the way that it does. Later chapters cover postwar variations on the Mustang and even jet-powered designs that evolved from the wartime lessons learned. A fitting subtitle for the book might have been "The history of the P-51 Mustang in its historical context".

The book is filled with first person quotes, which made the book a lot more interesting to read. I really got the feeling I was there with the designer (Edgar Schmued) as he overcame all the challenges he faced.

There's lots of photos of airplanes (mostly Mustangs) and of the people that played a role in its history. The focus on the captions is on technical accuracy. You won't find any captions of the "Pretty Mustang in flight" type. As best as possible, the captions tell you exactly which airplane you are looking at in the picture. If you like technical accuracy, you'll love this book.

The Bad

All of the pictures in the book are in black and white. Given their historical nature, my guess is that color was missing from the original pictures, too.

I was also hoping to find more technical details that would help me create a scale model. A couple of three-view drawings of the P51D variant are included, but almost all of the pictures of the Mustangs are side views or three-quarter views.

The Ugly

The biggest issue I have with the book is the reproduction quality of the pictures. They are similar in quality to what you find in a newspaper. I was frustrated that I couldn't see more details in the airplanes.

Conclusion

This is a unique book on an extremely popular scale model airplane subject. It works wonderfully well as a way of understanding the mindset and wartime constraints that led to the design of the fighter. If you are an aviation history buff, I can think of no better book to read. If you are a fan of the P-51, as I am, bring this book along on your next vacation. You won't regret it.

Backyard Bigfoot a Logical Book Review



AppId is over the quota
AppId is over the quota

I was curious about the possibility of stick signs being real evidence of interaction with Bigfoot, but I was also curious to know if Lisa A. Shiel, author of Backyard Bigfoot, had a new, logical perspective on Bigfoot and how the plausible existence of hairy forest giants might relate to UFOs, as it states on the book cover.

Shiel also discusses "orbs," but it seems that her outlook on these subjects as naive as those who staunchly "believe" that photographed orbs are manifestations of spirits from beyond, and that UFO's are proof that extraterrestrials or inter-dimensional beings maneuver through our airspace in highly advanced craft.

The bottom line is that there is absolutely no proof to substantiate these phenomena, and it is illogical to speculate based on belief alone.

I mean no disrespect to the author. This is an interesting, well written book, and she certainly has done her fair share of research. Her theories are entertaining, and there is much anthropological and paleontological information included in the book, though not always in the best context.

In some cases I notice that her interpretations are a bit of a stretch from what one might ordinarily gather from the information at hand. For example, in the first chapter, "Ancient Evidence," Shiel presents an image of a pottery piece decorated with a representation of Bes, an Egyptian "hairy dwarf" god.

Sheil tells us that Bes is often depicted with a feathered headdress, large feet, and sometimes as a bipedal lion-like creature but what the author fails to mention are the obvious wing-like appendages seen protruding from the back of the creature in the image presented. This depiction of Bes is as much a representation of a hairy hominid as it is of Mothman, for those who believe in the existence of such a thing.

The stick sign phenomenon is intriguing, and may indeed be evidence of a possible attempt at communication, or mere playfulness, by an unknown creature. Shiel has obviously done extensive experimentation with the stick sign phenomenon, but the fact that it continued at two very different locations, and on her property in both cases, may indicate that the phenomenon is a simple result of the misperception of her own environment.

I'm a skeptical person, but I try to keep an open mind about subjects like this. Backyard Bigfoot does contain some interesting information, and potential evidence that may or may not suggest the presence of hairy hominids on the author's property.

Much of what the author presents is assumption. She assumes a connection between hairy hominids and UFOs based on anecdotal evidence; stories. She assumes that orbs, and other likely photographic or optical anomalies, represent paranormal activity and not common dust, moisture, insects, or other airborne debris. Shiel also assumes that these orbs have a connection to the alleged hairy hominids she believes frequent her property.

Shiel suggests some sort of association between things like strange lights, mystery canids appearing on a motion-activated game camera, and her personal sighting of an out-of-place jaguar near her home when she lived in northern Texas. It seems that all of the world's paranormal mysteries found their way into her backyard. That is, if out of place jaguars, or wolf-like animals are truly paranormal phenomena.

It is common that many people who believe in the unexplained tend to experience all kinds of strangeness in their lives, while skeptics like me seem to miss it all. Everything becomes part of some great mystery to them, far beyond the comprehension of even the most educated scientists and thinkers.

On that note, one thing that Shiel doesn't hesitate to do, whenever she has the opportunity in this book, is to bash skeptics as a close-minded group with an agenda to shut the door on all hope for the believers. I got the distinct impression that Shiel views skeptics as the most illogical of people, when in fact the opposite is true. Unfortunately believers view skepticism as a threat.

Skeptics ask questions, and point out facts which believers tend to conveniently ignore, maybe for fear of change. It is not my goal to bash the author, she has written a fun book, and presents plenty of food for thought. There can be no belittling the author for amount of work she has done. She is an intelligent person, and the book is well researched, however, much of what she offers and interprets seems liberally colored by her belief.

Are Bigfoot responsible for the stick signs Shiel finds on her property? Maybe. Does Bigfoot exist? Maybe. But also probably not. It seems that the author, like many, is convinced of their existence and assumes that unknown hairy hominids are communicating with her through stick signs. Some of the stick sign formations do seem to be deliberate, while others could very well have just fallen out of a tree and landed that way.

There are many less mysterious woodland creatures capable of shuffling some sticks around too, during the course of gathering materials for a nest or den for example, or simply scurrying by. Even the wind can whip up a loose stick or twig and have them land as they may. To say that a found array of sticks are messages from, and evidence of, a creature that science has not found to exist is a stretch. Oh, there we go with science again.

Throughout the book are references to stick signs and rocks (some of which Shiel claims are evidence of hairy hominids' toolmaking skills), apparently showing up where they were not the day before. In this case, how is it possible that the author has such precise recollection of what is, or is not present on her property, and how can she be so certain as to how something got there?

Are we to believe that Shiel patrols her property on a daily basis making a detailed inventory of the contents of her land? Many of the passages in the book seem to indicate just that.

I will admit that my explanations above do not answer the riddle as to why Shiel seems to consistently get responses to her own placed stick signs. If an animal didn't just happen to shuffle over the sticks during the night, rearranging them a bit by mistake, then maybe there is something intelligent trying to communicate with her. But the evidence is very sketchy, and it does not necessarily have to be a Bigfoot.

Sheil also discusses mystery braids that appear in the manes of her horses, seemingly overnight. She describes the detail and intricacy of the braids, but at the same time she contradicts herself, referring to them as having a knotted appearance and being difficult to remove.

The photos Shiel presents of the braids show no real detail, and don't really help to support her claim. In some pictures it looks like she's showing nothing more than a tangle of hairs. Hard to say for sure. She is again making an assumption that the braids are the work of playful, hairy hominids, though she never claims to have seen any Bigfoot at work making stick signs or weaving the braids. These alleged events apparently happen overnight, miraculously, therefore we cannot assume that unknown creatures called Bigfoot are responsible for these events.

There is just no proof, despite the cute cover image, which seems more suited for a children's book than a serious examination of the Bigfoot phenomenon.

The book is interesting, but I must say that it is odd as well. It is a book about the paranormal and the author's belief, perfect for those who wish to continue to believe in such things.
