Introduced mammals are major drivers of extinction. Feral goats (Capra hircus) are particularly devastating to island ecosystems, causing direct and indirect impacts through overgrazing, which often results in ecosystem degradation and biodiversity loss. Removing goat populations from islands is a powerful conservation tool to prevent extinctions and(More)
Introduced mammals are major drivers of extinction and ecosystem change. As omnivores, feral pigs (Sus scrofa) are responsible for wholesale adverse effects on islands. Here, we report on the eradication of feral pigs from Santiago Island in the Gal apagos Archipelago, Ecuador, which is the largest insular pig removal to date. Using a combination of ground(More)
© The Ecological Society of America www.frontiersinecology.org G fisheries provide approximately 16% of all protein consumed by humans, employ about 200 million people, and are valued at US$82 billion (Botsford et al. 1997; FAO Fisheries Department 2004). Eight percent, or 7.2 million tons, of the global catch is comprised of non-target species and(More)
Insular breeding seabirds are likely to be particularly vulnerable to introduced mammalian predators because they often lack behavioural, morphological and life-history defenses against predation. We studied the life-history of the black-vented shearwater (Puffinus opisthomelas) on Natividad Island, Baja California Sur, Mexico, to examine its vulnerability(More)
The use of Judas goats (JGs; Capra hircus) to locate remnant animals is a powerful tool for enhancing feral goat eradication efforts, being especially important to island conservation programs. JGs are goats that are captured, fitted with radio telemetry collars and released. As goats are gregarious, JGs search out and associate with other goats. They can(More)
C. Josh Donlan Department of Ecology and Evolutionary Biology, Cornell University Ithaca, New York 14853-2701 and Island Conservation University of California Long Marine Laboratories Santa Cruz, California 95060 Abstract Endangered species recovery often requires strategies that are risky, contentious, and difficult to implement. These qualities can lead(More)
Hurricane Katrina devastated New Orleans, Louisiana, USA, causing widespread damage to industry, housing, and infrastructure. The area of New Orleans East was particularly devastated, including a cluster of industries, such as a major foodprocessing plant, manufacturing facilities, and bulk material and gas processors. Although this area was well suited for(More)
This study documents the prevalence of simple renal cysts at various ages to produce a table of age-specific specificity values. The specificity of diagnosis for inherited renal cystic conditions depends primarily on the prevalence of simple renal cysts in disease-free subjects. To provide specificity data useful for the ultrasound assessment of individuals(More)
The sonographic parameters in portal hypertension (PHT) were examined in a consecutive population of 118 patients who had PHT diagnosed using specific endoscopic, sonographic and Doppler signs. A patent or enlarged paraumbilical vein was found in 85.6% of patients overall and 82.5% of patients with varices indicating a relatively high sensitivity. A portal(More)
