Data from: Relative costs and benefits of alternative reproductive phenotypes at different temperatures - genotype-by-environment interactions in a sexually selected trait

Agata Plesnar-Bielak, Anna Maria Skwierzyńska, Kasper Hlebowicz & Jacek Radwan
Background: The maintenance of considerable genetic variation in sexually selected traits (SSTs) is puzzling given directional selection expected to act on these traits. A possible explanation is the existence of a genotype-by-environment (GxE) interaction for fitness, by which elaborate SSTs are favored in some environments but selected against in others. In the current study, we look for such interactions for fitness-related traits in the bulb mite, a male-dimorphic species with discontinuous expression of a heritable...

Data from: Male-limited secondary sexual trait interacts with environment in determining female fitness

Anna M. Skwierzyńska, Jacek Radwan & Agata Plesnar-Bielak
Selection for secondary sexual traits (SSTs) elaboration may increase intralocus sexual conflict over the optimal values of traits expressed from shared genomes. This conflict can reduce female fitness, and the resulting gender load can be exacerbated by environmental stress, with consequences for a population’s ability to adapt to novel environments. However, how the evolution of SSTs interacts with environment in determining female fitness is not well understood. Here, we investigated this question using replicate lines...

Data from: Influence of haemosporidian infection status on structural and carotenoid‐based colouration in the blue tit (Cyanistes caeruleus)

Katarzyna Janas, Edyta Podmokła, Dorota Lutyk, Anna Dubiec, Lars Gustafsson, Mariusz Cichoń & Szymon Drobniak
Hypotheses postulating parasite-mediated mate choice intrinsically assume that parasitic infections deteriorate the quality of male ornamentation. Although this assumption has often been studied in the context of carotenoid-based colouration, only few studies investigated this with reference to structural feather colouration, which in many species plays a vital role in sexual selection. Here, using a three-years dataset from a wild blue tit (Cyanistes caeruleus) population, we examined the relationship between the haemosporidian infection status and the...

Data from: Balancing selection and introgression of newt immune-response genes

Anna Fijarczyk, Katarzyna Dudek, Marta Niedzicka & Wieslaw Babik
The importance of interspecific introgression as a source of adaptive variation is increasingly recognized. Theory predicts that beneficial genetic variants cross species boundaries easily even when interspecific hybridization is rare and gene flow is strongly constrained throughout the genome. However, it remains unclear whether certain classes of genes are particularly prone to adaptive introgression. Genes affected by balancing selection (BS) may constitute such a class, because forms of BS that favor novel, initially rare alleles,...

Data from: The genetic variance but not the genetic covariance of life-history traits changes towards the north in a time-constrained insect

Szymon Sniegula, Maria J. Golab, Szymon M. Drobniak & Frank Johansson
Seasonal time constraints are usually stronger at higher than lower latitudes and can exert strong selection on life history traits and the correlations among these traits. To predict the response of life history traits to environmental change along a latitudinal gradient, information must be obtained about genetic variance in traits and also genetic correlation between traits, i.e., the genetic variance-covariance matrix, G. Here, we estimated G for key life history traits in an obligate univoltine...

Data from: Lower haematocrit, haemoglobin and red blood cell number in zebra finches acclimated to cold compared to thermoneutral temperature

Jowita Niedojadlo, Agata Bury, Mariusz Cichoń, Edyta T. Sadowska & Ulf Bauchinger
Thermoregulation constitutes an important share of the energy budget of endotherms. Elevated thermoregulatory requirements must be met by oxygen supply through the blood, as heat is produced mainly via aerobic processes. In contrast to mammal studies, it remains unclear whether elevated thermoregulatory needs are followed by changes in haematological variables in birds. We investigated haematocrit (HCT), haemoglobin content per volume of blood (HGB), number of red blood cells (RBC), and size of the erythrocytes (RBC)...

Data from: Effects of interspecific coexistence on laying date and clutch size in two closely related species of hole‐nesting birds

Dhondt, Vladimir Remeš, Frank Adriaensen, Clotilde Biard, Jordi Camprodon, Mariusz Cichoń, Blandine Doligez, Anna Dubiec, Marcel Eens, Tapio Eeva, Anne E. Goodenough, Andrew G.

Nager, Jan-Åke Nilsson … & Ruedi G. Nager
Coexistence between great tits Parus major and blue tits Cyanistes caeruleus, but also other hole‐nesting taxa, constitutes a classic example of species co‐occurrence resulting in potential interference and exploitation competition for food and for breeding and roosting sites. However, the spatial and temporal variations in coexistence and its consequences for competition remain poorly understood. We used an extensive database on reproduction in nest boxes by great and blue tits based on 87 study plots across...

Data from: Genomics of end-Pleistocene population replacement in a small mammal

Petr Kotlik, Silvia Marková, Mateusz Konczal, Wieslaw Babik & Jeremy B. Searle
Current species’ distributions at high latitudes are the product of expansion from glacial refugia into previously uninhabitable areas at the end of the last glaciation. The traditional view of postglacial colonization is that southern populations expanded their ranges into unoccupied northern territories. Recent findings on mitochondrial DNA (mtDNA) of British small mammals have challenged this simple colonization scenario by demonstrating a more complex genetic turnover in Britain during the Pleistocene-Holocene transition where one mtDNA clade...

Data from: Interspecific transfer of parasites following a range-shift in Ficedula flycatchers

William Jones, Katarzyna Kulma, Staffan Bensch, Mariusz Cichoń, Anvar Kerimov, Miloš Krist, Toni Laaksonen, Juan Moreno, Pavel Munclinger, Fred Slater, Eszter Szöllősi, Marcel E. Visser, Anna Qvarnström & Fred M. Slater
Human-induced climate change is expected to cause major biotic changes in species distributions and thereby including escalation of novel host-parasite associations. Closely related host species that come into secondary contact are especially likely to exchange parasites and pathogens. Two competing theories, the Enemy Release Hypothesis, where invading hosts escape their original parasites; and the Novel Weapon Hypothesis, where invading hosts bring new parasites that have detrimental effects on native hosts, have been described to predict...

Data from: Flying between raindrops: strong seasonal turnover of several Lepidoptera groups in lowland rainforests of Mount Cameroon

1. Although seasonality in the tropics is often less pronounced than in temperate areas, tropical ecosystems show seasonal dynamics as well. Nevertheless, individual tropical insects’ phenological patterns are still poorly understood, especially in the Afrotropics. To fill this gap, we investigated biodiversity patterns of Lepidoptera communities at three rainforest localities in the foothills of Mount Cameroon, West Africa, one of the wettest places in the world. 2. Our multi-taxa approach covered six lepidopteran groups (fruit-feeding...

Data from: Lineages evolved under stronger sexual selection show superior ability to invade conspecific competitor populations

Joanne L. Godwin, Lewis G. Spurgin, L. Michalczyk, Oliver Y. Martin, Alyson J. Lumley, Tracey Chapman & Matthew J.G. Gage
Despite limitations on offspring production, almost all multicellular species use sex to reproduce. Sex gives rise to sexual selection, a widespread force operating through competition and choice within reproduction, however, it remains unclear whether sexual selection is beneficial for total lineage fitness, or if it acts as a constraint. Sexual selection could be a positive force because of selection on improved individual condition and purging of mutation load, summing into lineages with superior fitness. On...
