Data from: Hybridization during altitudinal range shifts: nuclear introgression leads to extensive cyto-nuclear discordance in the fire salamander

Ricardo Pereira, Iñigo Martínez-Solano, David Buckley & Ricardo J. Pereira
Ecological models predict that, in the face of climate change, taxa occupying steep altitudinal gradients will shift their distributions, leading to the contraction or extinction of the high-elevation (cold-adapted) taxa. However, hybridization between eco-morphologically divergent taxa commonly occurs in nature and may lead to alternative evolutionary outcomes, such as genetic merger or gene flow at specific genes. We evaluate this hypothesis by studying patterns of divergence and gene flow across three replicate contact zones between...

Data from: The oxidative cost of reproduction depends on early development oxidative stress and sex in a bird species

Ana Angela Romero Haro, Gabriele Sorci, Carlos Alonso-Alvarez & A. A. Romero-Haro
In the early 2000’s, a new component of the cost of reproduction was proposed: oxidative stress. Since then the oxidative cost of reproduction hypothesis has, however, received mixed support. Different arguments have been provided to explain this. Among them, the lack of a life history perspective on most experimental tests was suggested. We manipulated the levels of a key intracellular antioxidant (glutathione) in captive zebra finches (Taeniopygia guttata) during a short period of early life...

Data from: The role of environment and core-margin effects on range-wide phenotypic variation of a montane grasshopper

Víctor Noguerales, Vicente García-Navas, Pedro J. Cordero & Joaquín Ortego
The integration of genetic information with ecological and phenotypic data constitutes an effective approach to gain insight into the mechanisms determining interpopulation variability and the evolutionary processes underlying local adaptation and incipient speciation. Here, we use the Pyrenean Morales grasshopper (Chorthippus saulcyi moralesi) as study system to (i) analyze the relative role of genetic drift and selection on range-wide patterns of phenotypic differentiation and (ii) identify the potential selective agents (environment, elevation) responsible for variation....

Data from: Species interactions in occurrence data for a community of tick-transmitted pathogens

Agustin Estrada-Peña & José De La Fuente
Interactions between species of ticks, their realised range of hosts, the pathogens they carry and transmit, as well as the geographical distribution of species in the Western Palearctic, have been obtained based on evidence published between 1970–2014. These relationships were linked to remotely-sensed features of temperature and vegetation and used to extract the network of interactions among the organisms. The resulting datasets were focussed on niche overlap among ticks and hosts, species interactions and the...

Data from: The strength of the association between heterozygosity and probability of interannual local recruitment increases with environmental harshness in blue tits

Esperanza S. Ferrer, Vicente García-Navas, Juan José Sanz & Joaquín Ortego
The extent of inbreeding depression and the magnitude of heterozygosity–fitness correlations (HFC) have been suggested to depend on the environmental context in which they are assayed, but little evidence is available for wild populations. We combine extensive molecular and capture–mark–recapture data from a blue tit (Cyanistes caeruleus) population to (1) analyze the relationship between heterozygosity and probability of interannual adult local recruitment and (2) test whether environmental stress imposed by physiologically suboptimal temperatures and rainfall...
