Data from: An inverse latitudinal gradient in speciation rate for marine fishes

Far more species of organisms are found in the tropics than in temperate and polar regions, but the evolutionary and ecological causes of this pattern remain controversial1,2. Tropical marine fish communities are much more diverse than cold-water fish communities found at higher latitudes3,4, and several explanations for this latitudinal diversity gradient propose that warm reef environments serve as evolutionary ‘hotspots’ for species formation5,6,7,8. Here we test the relationship between latitude, species richness and speciation rate...

Data from: Inter-chromosomal coupling between vision and pigmentation genes during genomic divergence

Kosmas Hench, Marta Vargas, Marc P. Höppner, W. Owen McMillan & Oscar Puebla
Recombination between loci underlying mate choice and ecological traits is a major evolutionary force acting against speciation with gene flow. The evolution of linkage disequilibrium between such loci is therefore a fundamental step in the origin of species. Here, we show that this process can take place in the absence of physical linkage in hamlets—a group of closely related reef fishes from the wider Caribbean that differ essentially in colour pattern and are reproductively isolated...

Data from: Spatial contraction of demersal fish populations in a large marine ecosystem

Alessandro Orio, Ulf Bergström, Ann-Britt Florin, Andreas Lehmann, Ivo Šics & Michele Casini
Aim: The interdependencies between trophic interactions, environmental factors and anthropogenic forcing determine how species distributions change over time. Large changes in species distributions have occurred as a result of climate change. The objective of this study was to analyse how the spatial distribution of cod and flounder have changed in the Baltic Sea during the past four decades characterized by large hydrological changes. Location: Baltic Sea Taxon: Cod (Gadus morhua) and flounder (Platichthys flesus) Methods:...

Data from: Disentangling structural genomic and behavioral barriers in a sea of connectivity

Julia M. I. Barth, David Villegas-Ríos, Carla Freitas, Even Moland, Bastiaan Star, Carl André, Halvor Knutsen, Ian Bradbury, Jan Dierking, Christoph Petereit, David Righton, Julian Metcalfe, Kjetill S. Jakobsen, Esben M. Olsen, Sissel Jentoft & Julia M.I. Barth
Genetic divergence among populations arises through natural selection or drift and is counteracted by connectivity and gene flow. In sympatric populations, isolating mechanisms are thus needed to limit the homogenizing effects of gene flow to allow for adaptation and speciation. Chromosomal inversions act as an important mechanism maintaining isolating barriers, yet their role in sympatric populations and divergence with gene flow is not entirely understood. Here, we revisit the question whether inversions play a role...
