A multi-platform package for the analysis of intra- and interspecific trait evolution

Gaboriau, Théo ; Mendes, Fábio K. ; Joly, Simon ; Silvestro, Daniele ; Salamin, Nicolas

In: Methods in Ecology and Evolution, 2020, p. -

Evolutionary forces affect the distribution of phenotypes both within and among species. Yet, at the macro‐evolutionary scale, the evolution of intraspecific variance is rarely considered. Here, we present an r and a BEAST 2 implementation that extends the JIVE (Joint inter‐ and Intraspecific Variance Evolution) model aimed at the analysis of continuous trait evolution at both inter‐...

Molecular ecology studies of species radiations: current research gaps, opportunities and challenges

la Harpe, Marylaure de ; Paris, Margot ; Karger, Dirk N. ; Rolland, Jonathan ; Kessler, Michael ; Salamin, Nicolas ; Lexer, Christian

In: Molecular Ecology, 2017, p. -

Understanding the drivers and limits of species radiations is a crucial goal of evolutionary genetics and molecular ecology, yet research on this topic has been hampered by the notorious difficulty of connecting micro- and macroevolutionary approaches to studying the drivers of diversification. To chart the current research gaps, opportunities and challenges of molecular ecology approaches to...

Genomic footprints of repeated evolution of CAM photosynthesis in a Neotropical species radiation

De La Harpe, Marylaure ; Paris, Margot ; Hess, Jaqueline ; Barfuss, Michael Harald Johannes ; Serrano‐Serrano, Martha Liliana ; Ghatak, Arindam ; Chaturvedi, Palak ; Weckwerth, Wolfram ; Till, Walter ; Salamin, Nicolas ; Wai, Ching Man ; Ming, Ray ; Lexer, Christian

In: Plant, Cell & Environment, 2020/n/a//-

The adaptive radiation of Bromeliaceae (pineapple family) is one of the most diverse among Neotropical flowering plants. Diversification in this group was facilitated by shifts in several adaptive traits or “key innovations” including the transition from C3 to CAM photosynthesis associated with xeric (heat/drought) adaptation. We used phylogenomic approaches, complemented by differential...

A dedicated target capture approach reveals variable genetic markers across micro- and macro-evolutionary time scales in palms

de La Harpe, Marylaure ; Hess, Jaqueline ; Loiseau, Oriane ; Salamin, Nicolas ; Lexer, Christian ; Paris, Margot

In: Molecular Ecology Resources, 2019, p. -

Understanding the genetics of biological diversification across micro‐ and macro‐ evolutionary time scales is a vibrant field of research for molecular ecologists as rapid advances in sequencing technologies promise to overcome former limitations. In palms, an emblematic, economically and ecologically important plant family with high diversity in the tropics, studies of diversification at...

‘Next generation’ biogeography: towards understanding the drivers of species diversification and persistence

Lexer, Christian ; Mangili, Sofia ; Bossolini, Eligio ; Forest, Felix ; Stölting, Kai N. ; Pearman, Peter B. ; Zimmermann, Niklaus E. ; Salamin, Nicolas

In: Journal of Biogeography, 2013, p. -

The drivers of species diversification and persistence are of great interest to current biogeography, especially in those global biodiversity ‘hotspots’ harbouring most of Earth's animal and plant life. Classical multispecies biogeographical work has yielded fascinating insights into broad-scale patterns of diversification, and DNA-based intraspecific phylogeographical studies have started to...
