Intraspecific life history attributes of growth, survival, and reproduction can vary in
response to changes in the physical environment. These changes can induce a cascading effect
across trophic levels. In marine systems, shifts in ocean conditions such as warm and cold phases
of ENSO can change primary production in benthic...

This paper presents a parallel implementation and validation of an accurate and efficient three-dimensional computational model (3D numerical wave tank), based on fully nonlinear potential flow (FNPF) theory, and its extension to incorporate the motion of a laboratory snake piston wavemaker, as well as an absorbing beach, to simulate experiments...
1. The evaluation of the age and growth of animal populations is essential for understanding and
predicting how populations will respond to changes in environmental conditions and anthropogenic
stressors.
2. We used a novel, von Bertalanffy hierarchical modelling approach to quantify relationships between
the growth of three freshwater mussel species...
Teen pregnancy is associated with a host of deleterious outcomes for girls such as drug use and poor parenting. Thus, reducing teen pregnancy rates could improve long-term developmental outcomes for girls, improving adjustment during young adulthood. Based on the positive effects of Multidimensional Treatment Foster Care (MTFC) relative to group...
We quantified the patterns in macroinvertebrate assemblages and their
associated environmental gradients from 457 least-disturbed wadeable
stream sites across the 48 contiguous United States sampled as part
of US EPA’s National Wadeable Stream Assessment. The majority of the
variation in assemblage composition at the finest taxonomic resolution
was related to...
Two large-resistance realisation schemes are proposed using switched-capacitor
circuits. The equivalent resistance of the array realisation
increases as the third power of the number of capacitor pairs, and
that of the ladder realisation increases exponentially. The equivalent
resistance for the ladder scheme also grows with the capacitance
ratio. Using these...
