Elucidating processes and mechanisms involved in rapid local adaptation to varied environments is a poorly understood but crucial component in management of invasive species. Recent studies have proposed that genetic and epigenetic variation could both contribute to ecological adaptation, yet it remains unclear on the interplay between these two co...
The set of four closely related solitary ascidians Ciona spp. were once considered a single cosmopolitan species, Ciona intestinalis, but are now recognized as genetically and morphologically distinct species. The possibility of ecological differences between the species was not widely considered in studies preceding the schism of Ciona spp. Conseq...
Individual body size strongly influences the trophic role of marine organisms and the structure and function of marine ecosystems. Quantifying trophic position-individual body size relationships (trophic allometries) underpins the development of size-structured ecosystem models to predict abundance and the transfer of energy through ecosystems. Tro...
Climate‐driven species redistribution is pervasive and accelerating, yet the complex mechanisms at play remain poorly understood. The implications of large‐scale species redistribution for natural systems and human societies have resulted in a large number of studies exploring the effects on individual species and ecological communities worldwide....
The vase tunicate Ciona intestinalis is an invasive sea squirt that poses several challenges for coastal marine ecosystems and human activities. Despite its widespread distribution, temporal and spatial variability in population abundances is high. We tested whether this variation could be explained by 4 abiotic variables: temperature, salinity, pH...
Biological invasion provides a promising system for studying rapid environmental accommodation and adaptation in the wild. Mounting evidence indicates that epigenetic modifications such as DNA methylation play crucial roles in rapid local accommodation and adaptation. Thus, we hypothesize that different local environments can trigger methylation di...
