Journal clubs

The journal clubs are platforms for inspiration and for talking about the science which may have implications for and may stimulate our own research in new and exciting directions; and for learning interactively what is good science. Students are especially encouraged to join in.

The discussions tends to be stimulated by either questions regarding methodology and theory behind the the chosen paper or extensions and applications of the work described. There are only two requirements for the participants: curiousity and that you have read the paper. How active you are in the discussions is up to you.

On the mailing lists you will get reminders about the sessions, and occational discussions about the journal club and possible papers for discussion etc.

Ongoing

Time and place: Oct. 19, 2017 2:00 PM - 3:00 PM, Aquarium (3302)

Species' responses to changes in the environment can be either genetic or plastic, and adaptive or non-adaptive. Identifying the exact nature of such responses requires integration of population models and quantitative genetics theory.

Climate can affect populations not only directly and through resource availability, but also by altering predation risk. Such interactions can lead to unexpected or counter-intuitive responses, and considering them can be important for predicting  population responses to climate change.

Body size is often linked intricately with survival and reproductive rates, and therefore affects population dynamics. It is not unlikely for population collapses to be preceded by a change in body size distributions. If those changes happen long enough in advance, they may serve as early warning signals to predict population collapses.

Abstract

For the human population to maintain a constant size from generation to generation, an increase in fertility must compensate for the reduction in the mean fitness of the population caused, among others, by deleterious mutations. The required increase in fertility due to this mutational load depends on the number of sites in the genome that are functional, the mutation rate, and the fraction of deleterious mutations among all mutations in functional regions. These dependencies and the fact that there exists a maximum tolerable replacement level fertility can be used to put an upper limit on the fraction of the human genome that can be functional. Mutational load considerations lead to the conclusion that the functional fraction within the human genome cannot exceed 25%, and is probably considerably lower.

Body mass is an important indicator of general condition as it reflects energy accessible for survival and reproduction. Recent evidence show that several species have experienced shifts in their body mass due to climate change. In the monogamous wandering albatross, average body mass and breeding success has increased over the last years. Surprisingly, the increase in breeding success seems to be due to heavier fathers investing more in their sons.

Most demographic population models ignore males, but empirical evidence suggest that they should be included when vital rates are sex-specific. Assumptions about adult sex ratio, social structure, and mating system have been shown to affect estimates of extinction risk and projections of population dynamics. We discuss about when and how to apply two-sex models.

Our first statistics course warns us about making predictions beyond the observed range of data. What that means exactly is difficult to say though when we use more complex models with link functions, higher order effects and interactive terms. We discuss a quantitative method for assessing bias when extrapolating.
