Commercial farming of Atlantic salmon in Scotland started in 1969 and has since expanded to produce >179,000 t yr. A government department has published annual statistics and information on the seawater and freshwater sub-sectors of the Scottish salmon farming industry since 1979, and this review collates and discusses metrics covering aspects of production, farm sites and systems, fish perform...
Fish assemblages play a key role in stream ecosystems, and play a crucial role in the assessment of stream health. Physical habitat is a key component of stream ecosystems and plays a major role in determining biotic assemblages and stream integrity. There is increasing recognition of the role landscape factors play in determining biotic assemblages and stream integrity. Landscapes in Iowa and ...
A mixed-model moving-average approach to geostatistical modeling in stream networks. Ecology 91:644–651. South East Queensland (SEQ) is located on the eastern coast of Australia and is approximately 22,999 square km in size. It is a subtropical region with mean annual maximum temperatures ranging between 21 and 29 °C (EHMP, 2001) and total annual rainfall ranges between 900 and 1800 mm (Pusey e...
Seascape ecology is an emerging discipline focused on understanding how features of the marine habitat influence the spatial distribution of marine species. However, there is still a gap in the development of concepts and techniques for its application in the marine pelagic realm, where there are no clear boundaries delimitating habitats. Here we demonstrate that pelagic seascape metrics define...

This paper presents a historical overview and current perspective of the Automated Neuropsychological Assessment Metrics (ANAM) test system. We discuss the history of its development along with a synopsis of the evolution of computerized testing that has occurred and led to ANAM over the past 30 years within the Department of Defense (DoD). We include a description of our current system and tes...
BACKGROUND Spectrum effects refer to the phenomenon that test performance varies across subgroups of a population. When spectrum effects occur during diagnostic testing for cancer, difficult patient misdiagnoses can occur. Our objective was to evaluate the effect of test indication, age, gender, race, and smoking status on the performance characteristics of two commonly used diagnostic tests fo...
Marine protected areas (MPAs) are used to protect species, communities, and their associated habitats, among other goals. Measuring MPA efficacy can be challenging, however, particularly when considering responses at the community level. We gathered 36 abundance and 14 biomass data sets on fish assemblages and used meta-analysis to evaluate the ability of 22 distinct community diversity metrics...
The adaptations used by notothenioid fish to combat extreme cold may have left these fish poorly poised to deal with a changing environment. As such, the expected environmental perturbations brought on by global climate change have the potential to significantly affect the energetic demands and subsequent cellular processes necessary for survival. Despite recent lines of evidence demonstrating ...
