Call for abstracts for the ESEB 2025 symposium S02 "Addressing new and long-standing evolutionary questions with linkage disequilibrium based approaches". The ESEB 2025 Congress will be held at the International Convention Centre of Barcelona (CCIB) in Barcelona, Spain, from August 17 to 22,2025. Within this congress, we are happy to announce this symposium on approaches based on linkage disequilibrium to advance our understanding of evolution and we invite you to contribute with talks and posters. Many evolutionary processes, such as admixture, selection, drift, structural rearrangements and genetic incompatibilities, can result in non-random associations between loci (linkage disequilibrium), even in the absence of physical linkage. The availability of extensive genomic data for both model and non-model species has fuelled the development of novel and powerful methods to address fundamental questions in evolutionary biology using two-locus statistics, such as correlations in allele frequencies and variance in heterozygosity. These approaches have revolutionized our ability to infer demographic history across various organisms, including humans, expanded our ability to identify genetic incompatibilities underpinning speciation events, enhanced the power of genome-wide association studies (GWAS) and quantitative trait loci (QTL) mapping, and opened new avenues for investigating parallel evolution in non-model taxa, even when the traits under selection are unknown. In this symposium, we aim to showcase how the analyses of genome-wide patterns of linkage disequilibrium allow evolutionary biologists to answer exciting long-standing and new questions. Invited speakers Aaron Peace Ragsdale (University of Wisconsin-Madison, USA) Claudia Bank (University of Bern, Switzerland).
