A phylogenomic perspective on interspecific competition

The paper explores how discordant gene trees can reveal phylogenetic signal in interspecific interactions using Penicillium genomes and interaction data.

Selection on visual opsin genes in diurnal Neotropical frogs and loss of the SWS2 opsin in poison frogs

The paper identifies positive selection on opsin genes in diurnal Neotropical frogs and reports the loss of SWS2 opsin in poison frogs, suggesting implications for their visual adaptation and chemical ecology.

Multimodal disease transmission as a limiting factor for the spatial extent of a host plant

The paper investigates how multimodal disease transmission affects the spatial distribution of alpine carnations, finding that combined frequency- and density-dependent transmission mechanisms drive population decline and potential extinction.

Understanding the emergence of contingent and deterministic exclusion in multispecies communities

The paper develops a theoretical framework to explain deterministic and contingent competitive exclusion in multispecies communities using an empirical plant competition system.

Ultra-rare variants drive substantial cis-heritability of human gene expression

This study estimates that ultra-rare variants contribute significantly to cis-heritability of gene expression, with singletons accounting for ~25% and most of that from variants absent in thousands of samples.

Viruses rule over adaptation in conserved human proteins

The paper shows that virus-interacting proteins, even when conserved across species, experience high adaptive evolution, with viruses driving over 75% of adaptation in the most conserved human proteins.

An evolutionary compass for detecting signals of polygenic selection and mutational bias

This paper develops a statistical method to detect mutational bias and selection signals using GWAS data, finding evidence for non-neutral processes in traits like BMI and schizophrenia.

Exploiting selection at linked sites to infer the rate and strength of adaptation

The paper develops a method to estimate adaptation rate and strength using genomic data, finding most human protein adaptation is weakly beneficial, but virus-interacting proteins show stronger and more frequent adaptation.

Priority effects and non-hierarchical competition shape species composition in a complex grassland community

The paper uses a population dynamic model to show that priority effects and non-hierarchical competition shape species composition in invaded grassland communities, with exotics outcompeting natives and exotic dominance driven by strong interspecific competition.
