Crustal fissuring on the crest of the southern East Pacific Rise at 17°15′–40′S

Creator:: Wright, Dawn J., Haymon, Rachel M., White, Scott M., and Macdonald, Ken C.
Abstract:: Fissure densities and widths have been mapped along the axial zone of the superfast spreading southern East Pacific Rise (EPR) at 17°15′–40′S with the near-bottom DSL-120 and Argo II imaging systems. We observe that the youngest lava flows (on a relative age scale) are sparsely fissured and that there is...

Assessment of motor behaviour among children and adolescents with Autism Spectrum Disorder

Creator:: Staples, K. L., MacDonald, M., and Zimmer, C.
Abstract:: Social communicative deficits are the hallmark characteristic of autism, also referred to as autism spectrum disorders (ASD). Given the depth of these social communicative deficits, the role of movement skills in development has gone relatively underexplored, by comparison. However, children with ASD demonstrate impaired performance of fundamental movement skills early...

The relationship of motor skills and adaptive behavior skills in young children with autism spectrum disorders

Creator:: MacDonald, Megan, Lord, Catherine, and Ulrich, Dale
Abstract:: Objective: To determine the relationship of motor skills and the core behaviors of young children with autism, social affective skills and repetitive behaviors, as indicated through the calibrated autism severity scores. Design: The univariate GLM tested the relationship of gross and fine motor skills measured by the gross motor scale...

Motor skills and calibrated autism severity in young children with autism

Creator:: MacDonald, Megan, Lord, Catherine, and Ulrich, Dale
Abstract:: In addition to the core characteristics of autism spectrum disorder (ASD) motor skill deficits are present, persistent and pervasive across age. Although motor skill deficits have been indicated in young children with autism they have not been included in the primary discussion of early intervention content. 159 young children with...

The Relationship of Motor Skills and Social Communicative Skills in School-Aged Children With Autism Spectrum Disorder

Creator:: MacDonald, Megan, Lord, Catherine, and Ulrich, Dale A.
Abstract:: Motor skill deficits are present and persist in school-aged children with autism spectrum disorder (ASD; Staples & Reid, 2010). Yet the focus of intervention is on core impairments, which are part of the diagnostic criteria for ASD, deficits in social communication skills. The purpose of this study is to determine...

¹⁴C and ¹³C characteristics of higher plant biomarkers in Washington margin surface sediments

Creator:: Feng, Xiaojuan, Benitez-Nelson, Bryan C., Montlucon, Daniel B., Prahl, Fredrick G., McNichol, Ann P., Xu, Li, Repeta, Daniel J., and Eglinton, Timothy I.
Abstract:: Plant wax lipids and lignin phenols are the two most common classes of molecular markers that are used to trace vascular plant-derived OM in the marine environment. However, their ¹³C and ¹⁴C compositions have not been directly compared, which can be used to constrain the flux and attenuation of terrestrial...

Susceptibility of Juvenile Steelhead to Avian Predation: the Influence of Individual Fish Characteristics and River Conditions

Creator:: Hostetter, Nathan J., Evans, Allen F., Roby, Daniel D., and Collis, Ken
Abstract:: Identification of the factors that influence susceptibility to predation can aid in developing management strategies to recover fish populations of conservation concern. Predator-prey relationships can be influenced by numerous factors, including prey condition, prey size, and environmental conditions. We investigated these factors by using juvenile steelhead Oncorhynchus mykiss from the...

Distribution and sources of organic matter in surface marine sediments across the North American Arctic margin

Creator:: Goni, Miguel A., O’Connor, Alison E., Kuzyk, Zou Zou, Yunker, Mark B., Gobeil, Charles, and Macdonald, Robie W.
Abstract:: As part of the International Polar Year research program, we conducted a survey of surface marine sediments from box cores along a section extending from the Bering Sea to Davis Strait via the Canadian Archipelago. We used bulk elemental and isotopic compositions, together with biomarkers and principal components analysis, to...

Prospects for Recovering Endemic Fishes Pursuant to the U.S. Endangered Species Act

Creator:: Williams, Jack E., Macdonald, Catherine A., Williams, Cindy Deacon, Weeks, Hal, Lampman, Georgina, and Sada, Don W.
Abstract:: If the success of the Endangered Species Act (ESA) is measured by the number of endangered species that have been recovered and delisted, then the act is not very successful. Only 15 species have been delisted because of recovery in the history of the ESA. The Borax Lake chub (Gila...
