Fort Clatsop National Memorial was established in 1958 to commemorate the culmination and the 1805 to 1806 winter encampment of the Lewis and Clark Expedition on the Oregon coast. In 2004, Congress authorized the expansion of the Fort Clatsop National Memorial from 51 ha (125 acres) to 1295 ha (3,200 acres) and renamed the National Park Service unit to Lewis and Clark National Historical Park (LEWI). LEWI now encircles the ecologically significant Columbia River estuary.

The objectives of this study were to (1) determine if a reproducing population of crayfish belonging to the C. acuminatus complex occurs in Valley Creek within VFNHP; (2) conduct a comprehensive survey of Valley Creek within VFNHP and produce a list of all the crayfish species that occur there; and (3) determine the basic life history characteristics (e.g., size structure, sex ratio), reproductive status, and habitat preferences of the crayfish species that occur in Valley Creek within VFNHP.

A wonderfully illustrated book filled with everything you would ever need to know about blue whales.... and Billy of course. This book is designed to make children's eyes light up with interest. Enjoy

The billfish is fixed at the apex of the oceanic food chain. Composed of sailfish, marlin, spearfish, and swordfish, they roam the pelagic waters of the Atlantic and are easily recognized by their long, spear-like beaks. Noted for their speed, size, and acrobatic jumps, billfish have for centuries inspired a broad spectrum of society. Even in antiquity, Aristotle, who assiduously studied the swordfish, named this gladiator of the sea xiphias - the sword. The Billfish Story tells the saga of this unique group of fish and those who have formed bonds with them - relationships forged by anglers, biologists, charter-boat captains, and conservationists through their pursuit, study, and protection of these species. More than simply reciting important discoveries, Stan Ulanski argues passionately that billfish occupy a position of unique importance in our culture as a nexus linking natural and human history. Ulanski, both a scientist and an angler, brings a rich background to the subject in a multifaceted approach that will enrich not only readers appreciation of billfish but the whole of the natural world.

The National Institute of Standards and Technology (NIST), in support of the National Oceanic and Atmospheric Administration s Marine Mammal Health and Stranding Response Program (NOAA/MMHSRP) conducts annual interlaboratory comparison exercises for the determination of chlorinated pesticides, polychlorinated biphenyl congeners, and trace elements in marine mammal tissues. These exercises provide one mechanism for laboratories to evaluate their measurement quality and comparability for these constituents in marine mammal tissues. In the 2003 exercise, 24 laboratories participated in determining the concentrations of selected polychlorinated biphenyl congeners (PCBs) and organochlorine pesticides in a homogenized blubber control material Marine Mammal Quality Assurance Exercise Homogenate VI (Homogenate VI) and Standard Reference Material (SRM) 1945 Organics in Whale Blubber. This report includes the results reported by the participating laboratories, combined consensus data results, and summary statistics for each analyte in the samples. The numerical indices used to assess laboratory performance are also discussed.

Consider that out there, somewhere, amongst the vastness of the seas, lives a single shark who swims, hunts, sleeps, thinks, and dreams...who may be dong any one of these activities at the same time you yourself are swimming, hunting, sleeping, thinking, and dreaming. Curious, isn't it? That both can share the same earth and do the same thing at the same time? We have some interesting commonalities. The 2nd book by Dr. Jaws is Carcharias taurus. Carcharias taurus relates the biology and essence of the Sandtiger: a docile species with a fearsome appearance andgruesome beginning. Included is the ghoststory, The Curse of Edward Teach, where the species plays a chilling roll in a tale of The Graveyard of the Atlantic, and one of its most infamous residents....

This report presents a summary of the forest condition data collected in 2007 by the National Capital Region Network Inventory and Monitoring Program. Forest condition was monitored on 100 forest plots randomly located throughout the National Capital Region. This data is part of a long term forest monitoring effort that will include 400 forest plots. One hundred plots will be monitored each year, and any particular plot will be monitored once every four years. As this is the first time that these plots are monitored only status data but not trend data is available.

In 2000, the National Capital Region Inventory and Monitoring Network (NCRN) initiated a deer monitoring program to collect information on deer densities. The program is carried out through fall spotlight surveys in Antietam National Battlefield, Catoctin Mountain Park, Chesapeake and Ohio Canal National Historic Park- Gold Mine Tract, George Washington Memorial Parkway - Great Falls Park, Manassas National Battlefield Park, Monocacy National Park, National Capital Parks - East (Greenbelt and Piscataway units), Prince William Forest Park, and Rock Creek Park. Pellet-group counts are used in Harpers Ferry National Historic Park because of the lack of a road network. This report summarizes and analyzes the fall 2007 spotlight surveys and the 2007 fall-winter pellet-group count.

Rising at 11,750 feet in the Sangre de Cristo range and snaking 926 miles through New Mexico and Texas to the Rio Grande, the Pecos River is one of the most storied waterways in the American West. It is also one of the most troubled. In 1942, the National Resources Planning Board observed that the Pecos River basin ""probably presents a greater aggregation of problems associated with land and water use than any other irrigated basin in the Western U.S."" In the twenty-first century, the river's problems have only multiplied. Bitter Waters, the first book-length study of the entire Pecos, traces the river's environmental history from the arrival of the first Europeans in the sixteenth century to today. Running clear at its source and turning salty in its middle reach, the Pecos River has served as both a magnet of veneration and an object of scorn. Patrick Dearen, who has written about the Pecos since the 1980s, draws on more than 150 interviews and a wealth of primary sources to trace the river's natural evolution and man's interaction with it. Irrigation projects, dams, invasive saltcedar, forest proliferation, fires, floods, flow decline, usage conflicts, water quality deterioration - Dearen offers a thorough and clearly written account of what each factor has meant to the river and its prospects. As fine-grained in detail as it is sweeping in breadth, the picture Bitter Waters presents is sobering but not without hope, as it also extends to potential solutions to the Pecos River's problems and the current efforts to undo decades of damage. Combining the research skills of an accomplished historian, the investigative techniques of a veteran journalist, and the engaging style of an award-winning novelist, this powerful and accessible work of environmental history may well mark a turning point in the Pecos's fortunes.

Did you ever hear of a fish that can whistle? Or a fish that can move a boulder? You can read about them in I Like the Fish, second in a series of picture books for 4- to 8-year-olds that explores the whimsical side of nature, with colorful pictures and clever text, portraying fish and their idiosyncrasies.
