Review of \u3ci\u3eRaptors of New Mexico\u3c/i\u3e. Edited by Jean-Luc E. Cartron.
As a raptor specialist, I eagerly look forward to the publication of state and regional books on birds of prey, typically rich with hard-to-find locally flavored information on distribution and biology. With the publication of Raptors of New Mexico, my home state has joined the ranks of the handful of states blessed with such volumes, and in fine form. This is an impressive work both in size and content, but the first thing anyone will notice are the photographs-hundreds, most top-notch, many capturing moods, scenes, and places unique to New Mexican raptors. In many ways the book is a showcase for the 109 or so photographers who contributed images, but there is much more here than gorgeous pictures. Raptors of New Mexico includes chapters on the 19 species of Accipitriformes, five species of Falconiformes, and 13 species of Strigiformes that regularly occur in New Mexico, as well as a single chapter covering seven additional raptor species considered casual or accidental. Each species chapter includes sections on distribution (with detailed range maps), habitat associations, nesting, diet and foraging, predation and interspecific interactions, status and management, and references
Preliminary Findings on the Foraging Ecology of a Northern Bobwhite Predator in North Florida: The Cooper\u27s Hawk (Accipiter cooperii)
As part of a larger study of the ecology of the Cooper\u27s hawk (Accipter cooperii) in the Northern Highlands and Red Hills regions of North Florida, we collected data on landscape-level habitat selection, home range size, and diet of resident adult Cooper\u27s hawks from April 1996-April 1997 on study areas in northern Leon County (Tall Timbers Research Station) and western Suwannee County. Data on habitat selection and home range size were collected by intensively tracking 8 radio-instrumented adult Cooper\u27s hawks (3 males and 5 females) originally captured while breeding at nest sites on the study areas. Diet information on the study areas was obtained by observing Cooper\u27s hawk prey deliveries at nest sites from blinds, by collecting prey remains from prey handling perches around nests, and by documenting prey captures by radio-tagged hawks. In this poster we present some preliminary findings from the first year of this study that may have implications for wildlife managers wanting to minimize rates of predation on bobwhites by Cooper\u27s hawks
Clinical and Experimental Applications of NIR-LED Photobiomodulation
This review presents current research on the use of far-red to near-infrared (NIR) light treatment in various in vitro and in vivo models. Low-intensity light therapy, commonly referred to as “photobiomodulation,” uses light in the far-red to near-infrared region of the spectrum (630–1000 nm) and modulates numerous cellular functions. Positive effects of NIR–light-emitting diode (LED) light treatment include acceleration of wound healing, improved recovery from ischemic injury of the heart, and attenuated degeneration of injured optic nerves by improving mitochondrial energy metabolism and production. Various in vitro and in vivo models of mitochondrial dysfunction were treated with a variety of wavelengths of NIR-LED light. These studies were performed to determine the effect of NIR-LED light treatment on physiologic and pathologic processes. NIRLED light treatment stimulates the photoacceptor cytochrome c oxidase, resulting in increased energy metabolism and production. NIR-LED light treatment accelerates wound healing in ischemic rat and murine diabetic wound healing models, attenuates the retinotoxic effects of methanol-derived formic acid in rat models, and attenuates the developmental toxicity of dioxin in chicken embryos. Furthermore, NIR-LED light treatment prevents the development of oral mucositis in pediatric bone marrow transplant patients. The experimental results demonstrate that NIR-LED light treatment stimulates mitochondrial oxidative metabolism in vitro, and accelerates cell and tissue repair in vivo. NIR-LED light represents a novel, noninvasive, therapeutic intervention for the treatment of numerous diseases linked to mitochondrial dysfunction
Unusual raptor nests around the world
From surveys in many countries, we report using unusual nesting materials (e.g., paper money, rags, metal, antlers, and large bones) and unusual nesting situations. For example, we documented nests of Steppe Eagles [Aquila nipalensis] and Upland Buzzards [Buteo hemilasius] on the ground beside well-traveled roads, Saker Falcon [Falco cherrug] eyries in attics and a cistern, and Osprey [Pandian haliaetus] nests on the masts of boats and on a suspended automobile. Other records include a Golden Eagle [A. chrysaelos] nest 7.0 m in height, believed to be the tallest nest ever described, and, for the same species, we report nesting in rudimentary, nests. Some nest sites are within a Few meters of known predators or competitors. These unusual observations may be important in revealing the plasticity of a species' behavioral repertoire

Final Environment Impact Statement: Double-crested Cormorant Management in the United States
Populations of Double-crested Cormorants have been increasing rapidly in many parts of the U.S. since the mid-1970s. This abundance has led to increased conflicts, both real and perceived, with various biological and socioeconomic resources, including recreational fisheries, other birds, vegetation, and hatchery and commercial aquaculture production. This document describes and evaluates six alternatives (including the proposed action) for the purposes of reducing conflicts associated with cormorants, enhancing the flexibility of natural resource agencies to deal with cormorant conflicts, and ensuring the long-term conservation of cormorant populations. There are four chapters that make up the critical components of an Environmental Impact Statement. Chapter 1, Purpose and Need, describes the purpose of and need for the action. Chapter 2, Alternatives, describes the six management alternatives that we considered: (1) Continue current cormorant management practices (No Action); (2) implement only nonlethal management techniques; (3) expand current cormorant damage management practices; (4) establish a new depredation order to address public resource conflicts (PROPOSED ACTION); (5) reduce regional cormorant populations; and (6) establish frameworks for a cormorant hunting season. Chapter 3, Affected Environment, introduces the reader to the environmental categories upon which the analysis of alternatives in chapter 4 is based: cormorant populations, fish, other birds, vegetation, Federally-listed Threatened and Endangered species, water quality and human health, economic impacts, fish hatcheries and environmental justice, property losses, and existence and aesthetic values. Chapter 4, Environmental Consequences, analyzes the predicted impacts of each alternative on the environmental categories outlined in chapter 3 and in comparison to the No Action alternative. The environmental analysis presented in Chapter 4 indicates that the PROPOSED ACTION: will cause the estimated take o
