In the early 1990s, true green or blue light-emitting diodes (LEDs) with enough intensity for commercial applications were not available. Eagle-Picher and North Carolina State University (NCSU) had achieved groundbreaking developments in creating zinc selenide blue and green lasers and LEDs, but needed financial assistance to continue the research and development. With funding from the Advanced...

The Great Blue Heron Ardea herodias fannini Chapman, 1901 in the Pacific northwest appears to have modified nesting behaviour in response to the strong recent recovery of the Bald Eagle (Haliaeetus leucocephalus (L., 1766)) population. Previously undescribed, herons now often nest in close association with some breeding eagles, even though eagles depredate heron nestlings, are implicated in the...

Eagle syndrome is an aggregate of symptoms caused by an elongated ossified styloid process, the cause of which remains unclear. This is a rare finding that often goes undetected in the absence of radiographic studies. In this case, we present the diagnostic CT and lateral view plain film radiography findings of a 39-year-old woman with clinical evidence of Eagle syndrome. Eagle syndrome can occ...

BACKGROUND Many nerve injuries have been associated with Eagle syndrome. The cranial nerves V, VII, IX, and X have been reported to be injured by the elongated styloid process in this syndrome. METHODS We describe a case of Eagle syndrome with atypical symptoms of hypoglossal nerve palsy and Horner syndrome. RESULTS A 56-year-old woman presented with right hypoglossal nerve palsy, right Hor...

Elongation of the styloid process occurs in 4-7% of individuals. In the majority this elongation is asymptomatic. Presence of oropharyngeal pain and dysphagia with such elongation is known as Eagle syndrome. The aetiology of Eagle syndrome is believed to be a reactive osseus hyperplasia of the styloid process in response to pharyngeal trauma or surgical intervention, such as tonsillectomy. We p...

Conservation of species threatened with imminent extinction may require drastic measures that can be emotionally charged, politically unsavory, and legally challenging. A complex example relates to the decline of the island fox (Urocyon littoralis), endemic to the California Channel Islands, off the coast of the United States. The island fox exists as six subspecies, each found on a separate is...

Increasing development across the western United States (USA) elevates concerns about effects on wildlife resources; the golden eagle (Aquila chrysaetos) is of special concern in this regard. Knowledge of golden eagle abundance and distribution across the western USA must be improved to help identify and conserve areas of major importance to the species. We used distance sampling and visual mar...
