Professor Otso Ovaskainen, Department of Biosciences, University of Helsinki will give a seminar, entitled "Statistical modelling of species communities"
Abstract: One central aim in community ecology is to understand the factors that determine the identities and abundances of species found at any given locality. Central concepts include regional and local species pools, environmental filtering and biotic assembly rules. A typical data set involves a sites x species matrix of presence-absences (or abundances), some environmental and geographical characteristics of the sites, and possibly some information on the ecological traits and phylogenetic relationships of the species. Empirical ecologists routinely analyze such data with different ordination methods, which provide intuitive and illustrative summaries of the data, but are not predictive nor mechanistically rooted to the concepts listed above. There is an increasing interest in developing alternative approaches, many of which can be considered as extensions of single-species distribution models. I present one of such approach, built in the standard framework of hierarchical generalized linear models. The model captures environmental filtering at the community-level model by measuring the amount of variation and covariation in the responses of individual species to various characteristics of their environment. Biotic assembly rules are reflected in the model with the help of an association matrix, which models positive or negative co-occurrence patterns not explained by the responses of the species to their environment. I use a sparse Bayesian factor approach to enable model parameterization with data on species-rich communities and thus high-dimensional association matrices. I illustrate the performance of the approach both with simulated and real data, and make links to more traditional approaches in community ecology.

Title: Is bigger really better? The hidden side to sexual selection in a wild mammal population.
Abstract: Sexual selection is assumed to be a strong and sustained source of directional selection, which should remove genetic variation over time. However, in wild populations, genetic variation generally persists in sexually selected traits. Consequently, this phenomenon has become a long-discussed paradox in the field of evolutionary biology. In wild Soay sheep, large horns confer an advantage in strong intra-sexual competition, yet there is substantial variation in horn size, with some males developing very small or vestigial horns. We identified genes underlying horn development using genome-wide association studies (GWAS), which allowed us to test the most commonly proposed explanations for the maintenance of sexually-selected genetic variation, such as genic capture ("good genes"), sexually antagonistic selection, and trade-offs between reproductive success and survival. I present the evidence for and against these mechanisms, and discuss the applications of our findings to other wild populations.

Tuesday, April 8
Jarle Tufto will have a talk titled: "Coevolution of bet-hedging, reaction norm slope and elevation in temporally autocorrelated environments".
Abstract: Using a quantitative genetic panmictic model with discrete non-overlapping generation I consider the joint evolution of bet-hedging, plasticity and adaptive tracking through genetic evolution in mean reaction norm elevation.  The macroenvironment influencing all individuals of a given generation fluctuates according to an autoregressive (Ornstein-Uhlenbeck) process.  The expressed phenotype and the phenotypic optimum of a given individual depends on the macroenvironments at the time of development and selection, respectively, and in addition, possibly individually correlated, microenvironmental deviations.  In addition, bet-hedging through independent evolution of the phenotypic variance is accomodated by a plastic response to a second independent white-noise microenvironmental variable.  Analytic approximations expressing the mutual dependencies between the three evolutionary responses are derived by assuming small evolutionary fluctuations in mean reaction norm slopes around values at which the expected values of the respective components of the selection gradients are zero.  I first show how the covariance between the mean reaction norm elevation and the macroenvironment generated by adaptive tracking through genetic evolution in mean elevation decrease with increasing plasticity and with the total phenotypic variance (through a reduction in heritability).  Secondly, if the variance of the mismatch between the population mean phenotype and the mean phenotypic optimum is sufficiently large, diversifying bet-hedging is adaptive and the total phenotypic variance evolves towards the difference between this mismatch variance and the square of the width of the stabilizing selection fitness function.  Plasticity and adaptive tracking in mean elevation, however, may make the mismatch variance too small such that the phenotypic variance instead evolves towards a minumum value imposed by a cost of environmental canalization.  Finally, I show that the mean reaction norm slope evolves towards the difference between the slopes of regressions of the optimal phenotype and mean elevation, respectively, on the environment at development.  This holds when bet-hedging is adaptive in which case the regressions are between population level quantities, and in the limit of a small mismatch variance in which case the regressions are between individual level quantities.  Thus, through the effect of plasticity on the individual level phenotype-optimum variance, microenvironmental variability may create selection for either less or more plasticity depending on the correlation between microenvironmental deviations at the time of development and selection.

  The numerical solution for the overall coevolutionary outcome is characterized by considerable overlap throughout large parts of the parameter space between the three forms of evolutionary responses.

Tuesday, April 1
Geir Hysing Bolstad will talk about whether or not (additive) genetic variation matters for the divergence of populations and species. The talk is based on his manuscript "Genetic Constraints and Predict Evolutionary Divergence in Dalechampia Blossoms".
If genetic constraints are important in during evolutionary divergence, then rates and direction of evolution should be related to trait evolvability. This simple test of the constraint hypothesis has yielded inconclusive results. We suggest this is due to inadequate measurements of evolutionary potential. Here, we use some recently developed measures of evolvability to test the genetic-constraint hypothesis with quantitative genetic data on floral morphology from the Neotropical vine Dalechampia scandens (Euphorbiaceae). We also provide predictions from evolutionary models enabling us to investigate the plausibility of a range of evolutionary scenarios. We base our evolvability measures on estimated patterns of genetic variances and covariances from two species of in the D. scandens species complex. These measures were compared against rates of evolution and patterns of divergence among 24 populations in the two species. We found clear evidence for genetic constraints, and particularly so among traits that were tightly phenotypically integrated. The relationship between evolvability and evolutionary divergence is puzzling, however, because the observed evolvabilities are too large to constitute real constraints. This paradox can be explained by a combination of weak stabilizing selection around moving adaptive optima and small realized evolvabilities relative to the observed additive genetic variance.

Journal Club
The journal club tries to meet every Monday at 12:00 in the CBD lunch room and discuss a paper of general interest. All are welcome, and feel free to propose paper to discuss by contacting the administrator of the journal club, prof. Christophe Pélabon.

Monday 20 January we will discuss the paper by Gaillard and Yoccoz (2003) Temporal variation in survival of mammals: a case of environmental canalization? Ecology 84, 3294–3306.

R Seminars
R seminars are given once every month by CBD-members on a topic that he/she think can be of general interest. The seminars are the first Tuesday in the month at 13:00 in the CBD-room, and are open for all to join. Anyone that feel they can contribute by giving a seminar can contact the administrator of the R meetings, dr Geir Hysing Bolstad.
