Data from: Rapid induction of the heat hardening response in an Arctic insect

Mathias Sørensen, Torsten Kristensen, Jannik Lauritzen, Natasja Noer, Toke Høye & Simon Bahrndorff
The ability to cope with increasing and more variable temperatures, due to predicted climate changes, through plastic and/or evolutionary responses will be crucial for the persistence of Arctic species. Here, we investigate plasticity of heat tolerance of the Greenlandic seed bug Nysius groenlandicus, which inhabits areas with widely fluctuating temperatures. We test the heat resistance and hardening capacity (plasticity) of N. groenlandicus using both static (heat knock down time, HKDT) and dynamic (critical thermal maximum,...

Data from: MHC variability in an isolated wolf population in Italy

Marco Galaverni, Romolo Caniglia, Elena Fabbri, Silvana Lapalombella & Ettore Randi
Small, isolated populations may experience increased extinction risk due to reduced genetic variability at important functional genes, thus decreasing the population’s adaptive potential. The major histocompatibility complex (MHC), a key immunological gene cluster, usually shows high variability maintained by positive or balancing selection in response to challenges by pathogens. Here we investigated for the first time, the variability of 3 MHC class II genes (DRB1, DQA1, and DQB1) in 94 samples collected from Italian wolves....

Data from: Strong costs and benefits of winter acclimatization in Drosophila melanogaster

Mads Fristrup Schou, Volker Loeschcke, Torsten Kristensen & Torsten Nygaard Kristensen
Studies on thermal acclimation in insects are often performed on animals acclimated in the laboratory under conditions that are not ecologically relevant. Costs and benefits of acclimation responses under such conditions may not reflect costs and benefits in natural populations subjected to daily and seasonal temperature fluctuations. Here we estimated costs and benefits in thermal tolerance limits in relation to winter acclimatization of Drosophila melanogaster. We sampled flies from a natural habitat during winter in...

Data from: Preservation of potassium balance is strongly associated with insect cold tolerance in the field: a seasonal study of Drosophila subobscura

Heath A. MacMillan, Mads F. Schou, Torsten N. Kristensen & Johannes Overgaard
There is interest in pinpointing genes and physiological mechanisms explaining intra- and interspecific variations in cold tolerance, because thermal tolerance phenotypes strongly impact the distribution and abundance of wild animals. Laboratory studies have highlighted that the capacity to preserve water and ion homeostasis is linked to low temperature survival in insects. It remains unknown, however, whether adaptive seasonal acclimatization in free-ranging insects is governed by the same physiological mechanisms. Here, we test whether cold tolerance...

Data from: Choosy wolves? Heterozygote advantage but no evidence of MHC-based disassortative mating

Marco Galaverni, Romolo Caniglia, Pietro Milanesi, Silvana Lapalombella, Elena Fabbri & Ettore Randi
A variety of nonrandom mate choice strategies, including disassortative mating, are used by vertebrate species to avoid inbreeding, maintain heterozygosity and increase fitness. Disassortative mating may be mediated by the major histocompatibility complex (MHC), an important gene cluster controlling immune responses to pathogens. We investigated the patterns of mate choice in 26 wild-living breeding pairs of gray wolf (Canis lupus) that were identified through noninvasive genetic methods and genotyped at 3 MHC class II and...

Bin Yang, Leilei Cui, Miguel Perez-Enciso, Aleksei Traspov, Richard P. M. A. Crooijmans, Natalia Zinovieva, Lawrence B. Schook, Alan Archibald, Kesinee Gatphayak, Christophe Knorr, Alex Triantafyllidis, Panoraia Alexandri, Gono Semiadi, Olivier Hanotte, Deodália Dias, Peter Dovč, Pekka Uimari, Laura Iacolina, Massimo Scandura, Martien A. M. Groenen, Lusheng Huang & Hendrik-Jan Megens
Background: Pigs were domesticated independently in Eastern and Western Eurasia early during the agricultural revolution, and have since been transported and traded across the globe. Here, we present a worldwide survey on 60K genome-wide single nucleotide polymorphism (SNP) data for 2093 pigs, including 1839 domestic pigs representing 122 local and commercial breeds, 215 wild boars, and 39 out-group suids, from Asia, Europe, America, Oceania and Africa. The aim of this study was to infer global...

Data from: Unexpected high genetic diversity in small populations suggests maintenance by associative overdominance

Mads F. Schou, Volker Loeschcke, Jesper Bechsgaard, Christian Schlötterer & Torsten N. Kristensen
The effective population size (Ne) is a central factor in determining maintenance of genetic variation. The neutral theory predicts that loss of variation depends on Ne, with less genetic drift in larger populations. We monitored genetic drift in 42 Drosophila melanogaster populations of different adult census population sizes (10, 50 or 500) using pooled RAD sequencing. In small populations, variation was lost at a substantially lower rate than expected. This observation was consistent across two...

Data from: Thermal acclimation and adaptation across populations in a broadly distributed soil arthropod

Anne Jensen, Tibebu Alemu, Temesgen Alemneh, Cino Pertoldi & Simon Bahrndorff
The relative contributions of phenotypic plasticity and adaptive evolution to the respons-es of species to climate change are poorly understood. It has been suggested that some species or populations will have to rely on their ability to adjust their phenotype rather than on adaptation through evolutionary adaptation. 2. We test the extent of intra- and inter-population patterns of acclimation and genetic varia-tion in multiple traits directly related to environmental tolerance limits in the broadly dis-tributed...

Next-generation phylogeography resolves post-glacial colonization patterns in a widespread carnivore, the red fox (Vulpes vulpes), in Europe

Allan McDevitt, Ilaria Coscia, Samuel S Browett, Aritz Ruiz-Gonzalez, Mark Statham, Inka Ruczynska, Liam Roberts, Joanna Stojak, Alain Frantz, Karin Norén, Erik Agren, Jane Learmount, Mafalda Basto, Carlos Fernandes, Peter Stuart, David G Tosh, Magda Sindicic, Tibor Andreanszky, Marja Isomursu, Marek Panek, Andrey Korolev, Innokentiy M Okhlopkov, Alexander P Saveljev, Bostjan Pokorny, Katarina Flajsman … & Jan Wójcik
Carnivores tend to exhibit a lack of (or less pronounced) genetic structure at continental scales in both a geographic and temporal sense using various mitochondrial DNA markers on modern and/or ancient specimens. This tends to confound the identification of refugial areas and post-glacial colonization patterns in this group. In this study we used Genotyping-by-Sequencing (GBS) to reconstruct the phylogeographic history of a widespread carnivore, the red fox (Vulpes vulpes), in Europe by investigating broad-scale patterns...

Data from: Species distribution models of the Spotted Wing Drosophila (Drosophila suzukii, Diptera: Drosophilidae) in its native and invasive range reveal an ecological niche shift

Iben V. Ørsted & Michael Ørsted
The Spotted Wing Drosophila (Drosophila suzukii) is native to Southeast Asia. Since its first detection in 2008 in Europe and North America, it has been a pest to the fruit production industry as it feeds and oviposits on ripening fruit. Here we aim to model the potential geographical distribution of D. suzukii. We performed an extensive literature review to map the current records. In total 517 documented occurrences (96 native and 421 invasive) was identified...

Data from: Heat hardening capacity in Drosophila melanogaster is life stage specific and juveniles show the highest plasticity

Neda Nasiri Moghadam, Tarmo Ketola, Cino Pertoldi, Simon Bahrndorff & Torsten Kristensen
Variations in stress resistance and adaptive plastic responses during ontogeny have rarely been addressed, despite the possibility that differences between life stages can affect species' range margins and thermal tolerance. Here, we assessed the thermal sensitivity and hardening capacity of Drosophila melanogaster across developmental stages from larval to the adult stage. We observed strong differences between life stages in heat resistance, with adults being most heat resistant followed by puparia, pupae and larvae. The impact...

Differentially regulated genes in the heart of benzene exposed TAC-instrumented mice

Igor N. Zelko, Sujith Dassanayaka, Marina V. Malovichko, Caitlin M. Howard, Lauren F. Garrett, Shizuka Uchida, Kenneth R. Brittian, Steven P. Jones & Sanjay Srivastava
Benzene is a ubiquitous environmental pollutant abundant in household products, petrochemicals, and cigarette smoke. Benzene is a well-known carcinogen in humans and experimental animals; however, little is known about the cardiovascular toxicity of benzene. Recent population-based studies indicate that benzene exposure is associated with an increased risk for heart failure. Nonetheless, it is unclear whether benzene exposure is sufficient to induce and/or exacerbate heart failure. We examined the effects of benzene (50 ppm, 6 h/day,...

Data from: \"Transcriptome resources for two non-model freshwater crustacean species\" in Genomic Resources Notes accepted 1 October 2014 to 30 November 2014

Mariella Baratti, Federica Cattonaro, Tiziana Di Lorenzo, Valentina Iannilli, Alessio Iannucci, Diana Maria Paola Galassi, Dragos Postolache & Giovanni Giuseppe Vendramin
The aim of this study was to characterize the whole transcriptomes of two common Mediterranean freshwater crustaceans: the copepod Eucyclops serrulatus (Fischer, 1851) and the amphipod Echinogammarus veneris Heller, 1865. Whole transcriptomic approaches may assist in studying the response to environmental pollution of species with little or no available genomic information, allowing the identification of genes involved in adaptation processes to polluted environments that can be studied in expression profile variation at a later stage....

Data from: North-south differentiation and a region of high diversity in European wolves (Canis lupus)

Astrid V. Stronen, Bogumiła Jędrzejewska, Cino Pertoldi, Ditte Demontis, Ettore Randi, Magdalena Niedziałkowska, Małgorzata Pilot, Vadim E. Sidorovich, Ihor Dykyy, Josip Kusak, Elena Tsingarska, Ilpo Kojola, Alexandros A. Karamanlidis, Aivars Ornicans, Vladimir A. Lobkov, Vitalii P. Dumenko & Sylwia D. Czarnomska
European wolves (Canis lupus) show population genetic structure in the absence of geographic barriers, and across relatively short distances for this highly mobile species. Additional information on the location of and divergence between population clusters is required, particularly because wolves are currently recolonizing parts of Europe. We evaluated genetic structure in 177 wolves from 11 countries using over 67K single nucleotide polymorphism (SNP) loci. The results supported previous findings of an isolated Italian population with...

Data from: European wildcat populations are subdivided into five main biogeographic groups: consequences of Pleistocene climate changes or recent anthropogenic fragmentation?

Federica Mattucci, Rita Oliveira, Leslie A. Lyons, Paulo C. Alves & Ettore Randi
Extant populations of the European wildcat are fragmented across the continent, the likely consequence of recent extirpations due to habitat loss and over-hunting. However, their underlying phylogeographic history has never been reconstructed. For testing the hypothesis that the European wildcat survived the Ice Age fragmented in Mediterranean refuges, we assayed the genetic variation at 31 microsatellites in 668 presumptive European wildcats sampled in 15 European countries. Moreover, to evaluate the extent of subspecies/population divergence and...

Data from: Unravelling the evolutionary history and future prospects of endemic species restricted to former glacial refugia

Orly Razgour, Irene Salicini, Carlos Ibáñez, Ettore Randi & Javier Juste
The contemporary distribution and genetic composition of biodiversity bear a signature of species’ evolutionary histories and the effects of past climatic oscillations. For many European species, the Mediterranean peninsulas of Iberia, Italy and the Balkans acted as glacial refugia and the source of range recolonization, and as a result, they contain disproportionately high levels of diversity. As these areas are particularly threatened by future climate change, it is important to understand how past climatic changes...

Data from: A Drosophila laboratory evolution experiment points to low evolutionary potential under increased temperatures likely to be experienced in the future

Mads F. Schou, Torsten N. Kristensen, Vanessa Kellermann, Christian Schlötterer & Volker Loeschcke
The ability to respond evolutionarily to increasing temperatures is important for survival of ectotherms in a changing climate. Recent studies suggest that upper thermal limits may be evolutionary constrained. We address this hypothesis in a laboratory evolution experiment, encompassing ecologically relevant thermal regimes. To examine the potential for species to respond to climate change, we exposed replicate populations of Drosophila melanogaster to increasing temperatures (0.3 °C every generation) for 20 generations, whereas corresponding replicate control...

Data from: Isolation by distance, resistance and/or clusters? Lessons learned from a forest-dwelling carnivore inhabiting a heterogeneous landscape

Aritz Ruiz-González, Samuel A. Cushman, María José Madeira, Benjamín J. Gómez-Moliner & Ettore Randi
Landscape genetics provides a valuable framework to understand how landscape features influence gene flow and to disentangle the factors that lead to discrete and/or clinal population structure. Here, we attempt to differentiate between these processes in a forest-dwelling small carnivore [European pine marten (Martes martes)]. Specifically, we used complementary analytical approaches to quantify the spatially explicit genetic structure and diversity and analyse patterns of gene flow for 140 individuals genotyped at 15 microsatellite loci. We...

Conservation genomic analysis of the Croatian indigenous Black Slavonian and Turopolje pig breeds

Boris Lukic, Maja Ferenčaković, Dragica Šalamon, Mato Čačić, Vesna Orehovački, Laura Iacolina, Ino Curik & Vlatka Cubric-Curik
The majority of the nearly 400 existing local pig breeds are adapted to specific environments and human needs. The demand for large production quantities and the industrialized pig production have caused a rapid decline of many local pig breeds in recent decades. Black Slavonian pig and Turopolje pig, the latter highly threatened, are the two Croatian local indigenous breeds typically grown in extensive or semi-intensive systems. In order to guide a long-term breeding program to...
