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: 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: 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...

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,...

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

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...

BackgroundRoutine CT scans may increasingly be used to document normal aortic size and to detect incidental abdominal aortic aneurysms.PurposeTo determine whether ultra-low-dose non-contrast CT (ULDNC-CT) can be used instead of the gold standard CT angiography (CTA) for assessment of maximal abdominal aortic diameter.Materials and MethodsThis retrospective study included 50 patients who underwent CTA and a normal-dose non–contrast CT for suspected renal artery stenosis. ULDNC-CT datasets were generated from the normal-dose non–contrast CT datasets using a...
