If you’ve ever had a medical check-up, did you wonder why they put a cuff around your forearm, gave it a squeeze, and made you sit still and quiet? Or why they asked you to open your mouth so they could stick a thermometer under your tongue? Or put that cold stethoscope against your chest while you took deep breaths followed by sticking a clothespin thingamabob on your finger? What’s up with all the gizmos and gadgets and why all the bother?
What’s up is that all of these instruments measure the conditions of some of the most important, life-supporting functions, or vital signs, which keep your carcass from becoming, well, a carcass. The squeezy cuff is reading your blood pressure, which indicates how strongly your blood is pumping through your pipes. The thermometer measures your core body temperature, which affects many chemical reactions in your body that supply energy for your cells. With a stethoscope, the swooshing sound of air moving in and out of your lungs can be listened to. And the clothespin doohickey tracks the amount of oxygen being carried by your blood. Vital signs are critical indicators of your body’s overall health. By tracking them as you grow and mature, these measurements can be used as a guide or reference point for when your body isn’t feeling all that great.
Now what does your blood pressure have to do with US National Parks? While human vital signs are important in evaluating your body’s health, ecological vital signs are indicators for measuring ecosystem health. An ecosystem is a community of living organisms like frogs, trees, or bacteria, and nonliving materials such as water, dirt, and rocks that are located together and interact on some level. In a healthy ecosystem, all of the living and nonliving members exist in a state of natural balance in harmony with their environment. When something new enters the community, say a strange weed or insect, or something in the environment shifts, such as the air temperature becoming warmer, the health of the ecosystem can be threatened. Monitoring ecological vital signs gives scientists a reference point or baseline of the natural condition and alerts them when there is a change. While a healthy ecosystem can continue to support all its members and adapt to change, sometimes changes are too great and members of the ecosystem become stressed and have a hard time keeping up.
Although US National Parks are some of the most protected areas on the planet, the ecological health of many of these carefully safeguarded lands is increasingly uncertain due to our rapidly changing global environment. Here we present a collection of articles about how we study and understand the health of park ecosystems by measuring and tracking the condition of ecological vital signs. This scientific data helps park managers protect the valued resources of our parks and lessen harmful impacts when change is inevitable.

There are many conferences, workshops and meetings annually around the world, each emphasizing a specialty area for scientific exploration and research. Yet in very few instances, if at all, do the multidisciplinary aspects of science get presented so one may see the diversity of dependencies these seemingly disparate disciplines actually have. The Explorers Club and the U. S. National Park Service collaborated to make a first attempt at what will continue to be an "ocean pulse'" effort; conferences combining the aquaculture sciences; the search for underwater antiquities and the marinelbio-technologies utilized to explore these areas. The purpose has been to bring together not just academicians to talk about their finding in the field or the laboratory, but to provide a forum for the practical applications of "technology" to expanding our worlds fisheries as well as to continue to explore our world's oceans; the earth's truly last frontier. After everything is said and done, we still know precious little about our ocean environments. Their influences on our lives are monumental and yet we continue to be very parochial and conservative in our dedication to exploring their depths and resources. We feel confident that this initial effort by our respective groups to awaken a realization in the public and private sectors of the need for a cross-disciplinary approach to scientific research in the marine environment, is a necessity as we approach the 21 st century.

The U.S. National Park Service needs much better scientific information to protect the nation's parks for future generations, and research must be an essential element in its mandate. Science and the National Parks examines the reasons why science is important to the national parks, reviews previous evaluations of research in the parks, and recommends ways to improve the current science program. The book stresses the need for two distinct but related approaches to research, called "science for the parks" and "parks for science." Science for the parks includes research to gain understanding of park resources and develop effective management strategies. The parks for science concept recognizes that the national parks are potentially very important to scientific investigations of broad national and global environmental problems and invaluable for understanding the ecological response to anthropogenic change. Science and the National Parks is a critical assessment of the problems hampering the current Park Service science program, providing strong recommendations to help the agency establish a true mandate for science, create separate funding and autonomy for the program, and enhance its credibility and quality.

A variety of air pollutants are emitted into the atmosphere from human-caused and natural emissions sources throughout the United States and elsewhere. These contaminants impact sensitive natural resources in wilderness, including the national parks. The system of national parks in the United States is among our greatest assets. This book provides a compilation and synthesis of current scientific understanding regarding the causes and effects of these pollutants within national park lands. It describes pollutant emissions, deposition, and exposures; it identifies the critical (tipping point) loads of pollutant deposition at which adverse impacts are manifested.

The first-person accounts in Taken by Bear in Glacier National Park provide a you-are-there perspective on human and grizzly bear encounters since the park’s founding in 1910. Most of these encounters have ended peacefully, but many have not. In order to most accurately tell the stories of those involved in the more deadly incidents, Kathleen Snow went directly to the source: the National Park Service archives. With help from personnel at park headquarters, Snow has collected more than 100 years’ worth of harrowing true stories that read like crime scene investigations and provide hard-learned lessons in outdoor safety. A must-read for fans of Taken by Bear in Yellowstone and the classic Bear Attacks: Their Causes and Avoidance by Stephen Herrero.
