This week we will discuss a paper by Dunn et al. regarding comparing functional genomic data across species.
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.

This Friday, April 28th, we're discussing a recent paper on the newest SSE model by Rabosky & Goldberg (2017): "FiSSE: A simple nonparametric test for the effects of a binary character on lineage diversification rates".

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.
This thursday, at the Speciation Journal Club, we will discuss a paper on Adaptation to Global Change via Transposable Element and Epigenetics, by Rey et al. 2016 (Trends in Ecology and Evolution)
This Friday, March 24th, we're discussing a recent paper by Cantalapiedra et al. (2017): "Decoupled ecomorphological evolution and diversification in Neogene-Quaternary horses".
Hope to see you there!
This thursday, at the Speciation Journal Club, we will discuss a paper on hybridization and cichlid adaptive radiations, by Meier et al. 2017 (Nature Communications)
This Friday, March 17th, we're discussing a paper by Love and Lugar (2013): "Dimensions of integration in interdisciplinary explanations of the origin of evolutionary novelty".
Note that one of the authors (Alan C. Love) will give two talks in Oslo next week, one on Developmental mechanisms and another on Evolution of novelty.
Hope to see you there!
This thursday, at the Speciation Journal Club, we will discuss a paper on Genomic islands of divergence , by Bay and Ruegg 2017 (Proceedings B)
The evolution of reaction norms such as thermal performance is tightly linked to ecological processes, and eco-evolutionary models can provide important insights especially in varying environments.
This thursday, at the Speciation Journal Club, we will discuss a paper on Transitions between phases of genomic differentiation during stick-insect speciation, by Riesch et al. 2017 (Nature Ecology & Evolution)
This thursday, at the Speciation Journal Club, we will discuss a paper on levels of nucleotide diversity in homologous regions of the avian genome, by Dutoit et al. 2017 (Proceedings B)
This Friday, February 24th, we're discussing a paper by Rabosky and Goldberg (2015): "Model Inadequacy and Mistaken Inferences of Trait-Dependent Speciation."
Hope to see you there!
The demographic buffering hypothesis states that the temporal variation in vital rates is smaller the more these vital rates contribute to fitness. The pattern is appears well supported, but recent evidence indicates that life histories may be buffered or labile, and that there is a phylogenetic signal in this.
This thursday, at the Speciation Journal Club, we will discuss a paper on reproductive isolation and speciation rate variation in nature, by Rabosky 2016 (BJLS)
There is increasing support for body size as an important factor determining population dynamics in both animal and plant species. Integral Projection Models (IPMs) make it possible to assess the interplay of body size and population dynamics, but does body size always matter?
This thursday, at the Speciation Journal Club, we will discuss a paper on Mega-evolutionary dynamics of the adaptive radiation of birds, by Cooney et al. 2017 (Nature)
This Friday, the 3rd of February, we will discuss a paper by Davis et al. from 2016 titled "Herbivory promotes dental disparification and macroevolutionary dynamics in grunters (Teleostei: Terapontidae), a freshwater adaptive radiation".
Hope to see you there!
This thursday, at the Speciation Journal Club, we will discuss a paper entitled "Multispecies coalescent delimits structure, not species" by Sukumaran and Knowles from PNAS (2017)
This Friday, the 27th of January, we will discuss a paper by Haber and Dworkin from 2017 called "Disintegrating the fly: A mutational perspective on phenotypic integration and covariation"
Hope to see you there!
This thursday, at the Speciation Journal Club, we will discuss a paper entitled "Shedding Light on the Grey Zone of Speciation along a Continuum of Genomic Divergence" by Roux et al. in PLoS Biology (2016)
This Friday, the 20th of January, we will discuss a paper by Chira and Thomas from 2016 called "The impact of rate heterogeneity on inference of phylogenetic models of trait evolution"
