Including the genetic values of the possible parents when analyzing pedigrees that contain MULT groups.

In a studbook, MULT is used in a parent ID field when the actual parent is unknown but the parent is known to be one of a set of possible parents. Probabilities of being the actual parent are assigned to each possible parent in the MULT group, and that information is used in the calculation of mean kinships (MKs). Parental probabilities are typically assigned based on the species biology and/or what was known about how the animals were being managed at the time of conception.

Survivorship pattern inaccuracies and inappropriate anthropomorphism in scholarly pursuits of killer whale ( ) life history: a response to Franks et al. (2016).

Franks et al. (2016) consider that the degree of error in estimated ages used to define survivorship patterns of northern and southern resident killer whale ( ) populations is of insignificant impact to estimates of the species' postreproductive lifespan (PRLS). We provide evidence that survival probabilities for killer whales using a dataset comprising estimated age animals differ significantly from that determined using data collected from known-age animals in the Pacific Northwest over the past 40 years.

Use of animals with partially known ancestries in scientifically managed breeding programs.

Animals with only partially known ancestry present a problem for population managers because it can be difficult to determine their relative genetic value to the population. So long as their ancestry is not completely unknown, population management software such as PMx can calculate a mean kinship for these animals, but that mean kinship is calculated such that there is no decrease in relative genetic value or "penalty" for only partially known ancestry. However, there is a longer-term genetic cost to having animals with only partially known ancestry in the population, and thus it is appropriate to "penalize" animals with partially known ancestry to some extent.

Comparisons of life-history parameters between free-ranging and captive killer whale () populations for application toward species management.

Data collected on life-history parameters of known-age animals from the northern (NR) and southern resident (SR) killer whales () of the eastern North Pacific were compared with life-history traits of killer whales located at SeaWorld (SEA) facilities. For captive-born SEA animals, mean age and body length at 1st estrus was 7.5 years and 483.

Healthy food procurement policy: an important intervention to aid the reduction in chronic noncommunicable diseases.

In 2010, unhealthy diets were estimated to be the leading risk for death and disability in Canada and globally. Although important, policies aimed at improving individual's skills in selecting and eating healthy foods has had a limited effect. Policies that create healthy eating environments are strongly recommended but have not yet been effectively and/or broadly implemented in Canada.

Stroke prevention and cognitive reserve: emerging approaches to modifying risk and delaying onset of dementia.

Demographic changes and improvements in health care are projected to result in dramatic increases in the prevalence of dementia. Alzheimer's disease is widely considered to be the primary cause of dementia - a disease for which there is currently no cure nor effective treatment, and for which it is thought that little can be done to mitigate risk. However, an increasing understanding of the role and extent of vascular contributions to the development of dementia, and appreciation of the interactions between stroke and Alzheimer's disease, suggest that targeting vascular risk factors may be very beneficial in reducing the impact of dementia.

Canadian initiatives to prevent hypertension by reducing dietary sodium.

Hypertension is the leading risk for premature death in the world. High dietary sodium is an important contributor to increased blood pressure and is strongly associated with other important diseases (e.g.

How many founders, how large a population?

The number of population founders and the size of the population are two important variables in determining how much gene diversity can be retained in a population. A model is developed to determine the most cost-effective balance of those two variables, based on comparing the marginal costs of increasing the number of founders vs. increasing the population size.
