Data from: “Darwin’s corollary” and cytoplasmic incompatibility induced by Cardinium may contribute to speciation in Encarsia wasps (Hymenoptera: Aphelinidae)

Marco Gebiola, Suzanne E. Kelly, Peter Hammerstein, Massimo Giorgini, Molly S. Hunter & Martha S. Hunter
The potential importance of cytoplasmic incompatibility (CI) – inducing bacterial symbionts in speciation of their arthropod hosts has been debated. Theoretical advances have led to a consensus that a role is plausible when CI is combined with other isolating barriers. However, the insect model systems Nasonia and Drosophila are the only two experimental examples documented. Here we analyzed the components of reproductive isolation between the parasitoid wasp Encarsia suzannae, which is infected by the CI-inducing...

Data from: Ocean acidification affects fish spawning but not paternity at CO2 seeps

Fish exhibit impaired sensory function and altered behaviour at levels of ocean acidification expected to occur owing to anthropogenic carbon dioxide emissions during this century. We provide the first evidence of the effects of ocean acidification on reproductive behaviour of fish in the wild. Satellite and sneaker male ocellated wrasse (Symphodus ocellatus) compete to fertilize eggs guarded by dominant nesting males. Key mating behaviours such as dominant male courtship and nest defence did not differ...

Data from: Retrotransposon proliferation coincident with the evolution of dioecy in asparagus

Alex Harkess, Francesco Mercati, Loredana Abbate, Michael McKain, J. Chris Pires, Tea Sala, Francesco Sunseri, Agostino Falavigna & Jim Leebens-Mack
Current phylogenetic sampling reveals that dioecy and an XY sex chromosome pair evolved once or possibly twice in the genus Asparagus. Although there appear to be some lineage-specific polyploidization events, the base chromosome number of 2n=2x=20 is relatively conserved across the Asparagus genus. Regardless, dioecious species tend to have larger genomes than hermaphroditic species. Here we test whether this genome size expansion in dioecious species is related to a polyploidization and subsequent chromosome fusion or...

Data from: Habitat mapping of coastal wetlands using expert knowledge and Earth observation data

Maria Adamo, Cristina Tarantino, Valeria Tomaselli, Giuseppe Veronico, Harini Nagendra & Palma Blonda
Long-term habitat mapping and change detection are essential for the management of coastal wetlands as well as for evaluating the impact of conservation policies. Earth observation (EO) data and techniques are a valuable resource for long-term habitat mapping. Although the use of EO data is well developed for the automatic production of land cover (LC) maps, this is not the same for habitat maps, which are highly related to biodiversity. In a previous paper, we...

Data from: Biocomplexity in populations of European anchovy in the Adriatic Sea

The sustained exploitation of marine populations requires an understanding of a species' adaptive seascape so that populations can track environmental changes from short- and long-term climate cycles and from human development. The analysis of the distributions of genetic markers among populations, together with correlates of life-history and environmental variability, can provide insights into the extent of adaptive variation. Here, we examined genetic variability among populations of mature European anchovies (n = 531) in the Adriatic...
