Genetic diversity can influence resilience and adaptative capacity of organisms to environmental change. Genetic diversity within populations is largely structured by reproduction, with the prevalence of asexual versus sexual reproduction often underpinning important diversity metrics that determine selection efficacy. Asexual or clonal reproduction is expected to reduce genotypic diversity and slow down adaptation through red...

Climate change is increasingly impacting ecosystems globally. Understanding adaptive genetic diversity and whether it will keep pace with projected climatic change is necessary to assess species’ vulnerability and design efficient mitigation strategies such as assisted adaptation. Kelp forests are the foundations of temperate reefs globally but are declining in many regions due to climate stress. A lack of knowledge of kelp's...

Aim How disjunct distributions arise and why organisms differ in diversification patterns remain some of the most compelling fundamental questions in biogeography. We carry out phylogeographical analyses of the pantropical liverwort genus Ceratolejeunea to identify its geographical origin and the dispersal routes by which it gained its Neotropical‐African disjunction. Furthermore, we investigate whether there is geographical s...
