Data from: Experimental contact zones reveal causes and targets of sexual selection in hybridizing lizards

Hannah E. A. MacGregor, Geoffrey M. While, Jade Barrett, Guillem Pérez I De Lanuza, Pau Carazo, Sozos Michaelides & Tobias Uller
Divergence in sexually selected traits in allopatry should affect the degree and direction of hybridization. However, few studies have established the causes and targets of sexual selection during secondary contact. Common wall lizards (Podarcis muralis) from north-central Italy have highly exaggerated male sexual traits compared to populations in Western Europe. Using experimental populations, we show that this creates asymmetries in male dominance, spatial habitat use and reproductive success upon secondary contact. Hybridization occurred almost exclusively...

Data from: Deceiving predators: linking distraction behavior with nest survival in a ground-nesting bird

Miguel Angel Gómez-Serrano & Pascual López-López
Individual behavior that minimizes predation risk is favored by natural selection. Ground-nesting birds employ different defensive behaviors as part of their antipredator strategies because they nest where a wide range of predators have access. We investigated the influence of distraction displays on breeding success in the Kentish Plover, Charadrius alexandrinus, in order to explore the role of the defensive behavior on nest survival. We quantified the intensity of defensive behavior of adult plovers in response...

Data from: The evolution of colour pattern complexity: selection for conspicuousness favours contrasting within-body colour combinations in lizards

Guillem Pérez I De Lanuza & Enrique Font
Many animals display complex colour patterns that comprise several adjacent, often contrasting colour patches. Combining patches of complementary colours increases the overall conspicuousness of the complex pattern, enhancing signal detection. Therefore, selection for conspicuousness may act not only on the design of single colour patches, but also on their combination. Contrasting long- and short-wavelength colour patches are located on the ventral and lateral surfaces of many lacertid lizards. As the combination of long- and short-wavelength-based...

Data from: Stable isotopes reveal differences in diet among reed bunting subspecies that vary in bill size

Júlio Manuel Neto, Luís De Oliveira Gordinho, Benjamin Vollot, Marcial Marín, Juan S. Monrós & Jason Newton
Reed bunting (Emberiza schoeniclus) subspecies vary considerably in bill size and shape and seem to be at an early stage of speciation, in which bill might be indirectly causing reproductive isolation. Hence, we evaluated whether bill size, as well as age and sex, are associated with foraging niche in three West European subspecies of reed bunting: the thin-billed schoeniclus, the intermediate-billed lusitanica and the thick-billed witherbyi. Blood sampling was undertaken at three sites in southwest...

Data from: Inbreeding removes sex differences in lifespan in a population of Drosophila melanogaster

Pau Carazo, Jared Green, Irem Sepil, Tommaso Pizzari & Stuart Wigby
Sex differences in ageing rates and lifespan are common in nature, and an enduring puzzle for evolutionary biology. One possibility is that sex-specific mortality rates may result from recessive deleterious alleles in ‘unguarded’ heterogametic X or Z sex chromosomes (the unguarded X hypothesis). Empirical evidence for this is, however, limited. Here, we test a fundamental prediction of the unguarded X hypothesis in Drosophila melanogaster, namely that inbreeding shortens lifespan more in females (the homogametic sex...
