Genomic footprints of a biological invasion: introduction from Asia and dispersal in Europe of the topmouth gudgeon (Pseudorasbora parva)

Facilitated by the intensification of global trading, the introduction and dispersal of species to areas in which they are historically non-native is nowadays common. From an evolutionary standpoint, invasions are paradoxical: not only non-native environments could be different from native ones for which introduced individuals would be ill-adapted, but also small founding population size should be associated with reduced adaptive potential. As such, biological invasions are considered valuable real-time evolutionary experiments. Here, we investigated the...

Data from: Microbial ‘gardening’ by a seaweed holobiont: surface metabolites attract protective and deter pathogenic epibacterial settlement

Mahasweta Saha & Florian Weinberger
1. Epimicrobial communities on seaweed surfaces usually contain not only potentially pathogenic, but also potentially beneficial microorganisms. Capacity of terrestrial plants for chemically mediated recruitment i.e. ‘gardening’ of bacterial communities in the rhizosphere was recently demonstrated. Empirical evidence directly linking such chemical ‘gardening’ with the beneficial role of gardened microbes in terrestrial plants is rare and largely missing for aquatic macrophytes. 2. Here we demonstrate that our model invasive seaweed holobiont Agarophyton vermiculophyllum possesses beneficial...

Data from: The evolution of microendemism in a reef fish (Hypoplectrus maya)

Benjamin M. Moran, Kosmas Hench, Robin S. Waples, Marc P. Höppner, Carole C. Baldwin, W. Owen McMillan & Oscar Puebla
Marine species tend to have extensive distributions, which are commonly attributed to the dispersal potential provided by planktonic larvae and the rarity of absolute barriers to dispersal in the ocean. Under this paradigm, the occurrence of marine microendemism without geographic isolation in species with planktonic larvae poses a dilemma. The recently described Maya hamlet (Hypoplectrus maya, Serranidae) is exactly such a case, being endemic to a 50-km segment of the Mesoamerican Barrier Reef System (MBRS)....

Data from: Non-native species spread in a complex network: the interaction of global transport and local population dynamics determines invasion success

Hanno Seebens, Elizabeta Briski, Sara Ghabooli, Tamara Shiganova, Hugh MacIsaac & Bernd Blasius
The number of released individuals, which is a component of propagule pressure, is considered to be a major driver for the establishment success of non-native species. However, propagule pressure is often assumed to result from single or few release events, which does not necessarily apply to the frequent releases of invertebrates or other taxa through global transport. For instance, the high intensity of global shipping may result in frequent releases of large numbers of individuals,...

Data from: Electrophysiological evidence for light-activated cation transport in calcifying corals

Isabelle Taubner, Marian Y. Hu, Anton Eisenhauer & Markus Bleich
Light has been demonstrated to enhance calcification rates in hermatypic coral species. To date, it remains unresolved whether calcifying epithelia change their ion transport activity during illumination, and whether such a process is mediated by the endosymbiotic algae or can be controlled by the coral host itself. Using a modified Ussing chamber in combination with H+ sensitive microelectrode measurements, the present work demonstrates that light triggers the generation of a skeleton positive potential of up...
