Plenary session I – Elena Conti

Comparative Genomics elucidates the convergent origins of floral heteromorphism

Convergent evolution is one of the most fundamental yet contentious issues in evolutionary biology. The rapid accumulation of high-quality reference genomes and transcriptomes now enables us to re-examine evolutionary convergence and parallelism in a new framework: Does convergence at the phenotypic level correspond to convergence or deep homology at the genotypic level? Do the same genes and genetic architectures underlie convergent traits, or can different genes be recruited to achieve the same phenotypic outcome? I will discuss these questions focusing on heterostyly in Primulaceae but within the broader framework of flowering plants.

Heterostyly evolved three times independently in Primulaceae, namely in Primula, Hottonia, and Androsace. Heterostylous taxa of Primulaceae typically comprise two different types of plants with distinct floral morphs characterized by reciprocally placed sexual organs and a heteromorphic incompatibility system that blocks self- or intra-morph fertilization. Heterostyly thus promotes cross-fertilization while preventing the harmful effects of self-fertilization, and it evolved at least 14 times in angiosperms. A supergene known as the S locus operates the genetic control of heterostyly. Despite the numerous genetic, morphological, and reproductive studies on heterostyly over the past 150 years, the molecular nature and evolutionary origins of the S locus remained unknown until recently. What are the genes and genetic architectures of the S locus? Are they the same in independent origins of heterostyly?

Did the S locus evolve through a single, large duplication followed by loss of intervening genes or through multiple, asynchronous gene duplications followed by translocations? We addressed these questions by generating highly contiguous, chromosome-scale, haplotype-phased assemblies of heterostylous and homostylous genomes of Primulaceae and performing comparative genomic analyses across Ericales, the order that includes Primulaceae. Primulaceae thus represent an ideal system to study evolution on repeat in the genomics era, clarifying the connections and disconnections of evolutionary convergence from the genotypic to the phenotypic level and back.

Elena Conti

My research revolves around the following fundamental questions in evolutionary biology: How is biological diversity partitioned at different temporal, spatial, and genomic scales? What are the processes that generate and eliminate biological diversity? How do geography, ecology, and genomes shape the evolution of biological diversity? I strive to address the complexity of these questions by […]

I am interested in the development of computational methods to understand evolutionary processes at the population and species level, for instance to study how past climatic and environmental changes have influenced the pattern of genetic diversity of a given species, or to detect evidence of local adaptations from genomic information.

Sonya Clegg

I am an evolutionary ecologist interested in the processes that promote divergence in wild vertebrate systems. To understand the processes of genetic, morphological and ecological/behavioural differentiation, I combine field and molecular ecology approaches in my research. I currently lead a long-term field project on natural selection, demography and behaviour in a bird population of silvereye […]

Plenary session III – Tim Coulson

Unifying ecology and evolution to understand why very large and very small species exist

Ecological changes can result in evolution of phenotypic traits and life history, which can impact population and community dynamics. These two processes interact to generate eco-evolutionary feedbacks. I will explain how we can empirically quantify and theoretically model these feedbacks by drawing on my research into the ecosystems of Yellowstone National Park and Trinidad’s freshwater streams. Although the framework I describe has had some success in linking population ecology, population genetics, life history theory, and quantitative genetics, one of the drawbacks of the approach I will describe is models can become quite complicated making them hard to analyse. I will describe a novel approach I have pioneered to simplify models to gain general, novel, ecological and evolutionary insight. I will illustrate the approach by demonstrating how to evolve both species with very large body sizes and slow life histories, and those with small body sizes and fast life histories.

My group and I research how demographic rates vary across genotypes, phenotypes and environments. We identify the ecological, evolutionary and conservation consequences of this variation. We use a mix of field observations, laboratory experiments, statistical analysis of data and the construction and analysis of mathematical models.

I study how the spatial and temporal arrangement of habitats influences biological diversity.  This issue relates to a number of fundamental questions in ecology that have challenged scientists for decades.  Questions include: Why do mountains have extraordinary biodiversity? What is the importance of niche partitioning in maintaining biological diversity? and How does the climate history […]
