Data from: Species distribution models of the Spotted Wing Drosophila (Drosophila suzukii, Diptera: Drosophilidae) in its native and invasive range reveal an ecological niche shiftIben 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 plasticityNeda 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...
In this video Researcher Christian Skov from DTU Aqua tells about the Citizen Science project “Fangstjournalen” and how Research Data Management, data sharing and following the FAIR guiding principles for research data can increase the impact and the value of the research - even beyond the scope of the project. This video is produced by four Danish Universities as part of a project financially supported by DEFF. The aim of the project is to identify...
Specialization of species is often studied in ecology but its quantification and meaning is disputed. More recently, ecological network analysis has been widely used as a tool to quantify specialization, but here its true meaning is also debated. However, irrespective of the tool used, the geographic scale at which specialization is measured remains central. Consequently, we use data sets of plant–pollinator networks from Brazil and the Canary Islands to explore specialization at local and regional...
Integrated genome-wide investigations of the housefly, a global vector of diseases reveal unique dispersal patterns and bacterial communities across farmsSimon Bahrndorff
Background:Houseflies (Musca domesticaL.) live in intimate association with numerous microorganisms and is a vector of human pathogens. In temperate areas, houseflies willoverwinter in environments constructed by humans and recolonize surrounding areas in early summer. However, the dispersal patterns and associated bacteria across season and location are unclear.We used genotyping-by-sequencing (GBS) for the simultaneous identification and genotyping of thousands of Single Nucleotide Polymorphisms (SNPs) to establish dispersal patterns of houseflies across farms. Secondly, we used16S rRNA...
Data from: Genome-wide analyses suggest parallel selection for universal traits may eclipse local environmental selection in a highly mobile carnivoreAstrid Vik Stronen, Bogumiła Jędrzejewska, Cino Pertoldi, Ditte Demontis, Ettore Randi, Magdalena Niedziałkowska, Tomasz Borowik, Vadim E. Sidorovich, Josip Kusak, Ilpo Kojola, Alexandros A. Karamanlidis, Janis Ozolins, Vitalii Dumenko & Sylwia D. Czarnomska
Ecological and environmental heterogeneity can produce genetic differentiation in highly mobile species. Accordingly, local adaptation may be expected across comparatively short distances in the presence of marked environmental gradients. Within the European continent, wolves (Canis lupus) exhibit distinct north–south population differentiation. We investigated more than 67-K single nucleotide polymorphism (SNP) loci for signatures of local adaptation in 59 unrelated wolves from four previously identified population clusters (northcentral Europe n = 32, Carpathian Mountains n =...
Data from: Effects of photoperiod on life-history and thermal stress resistance traits across populations of Drosophila subobscuraNeda N. Moghadam, Zorana K. Novicic, Cino Pertoldi, Torsten N. Kristensen & Simon Bahrndorff
Intro: Organisms use environmental cues to match their phenotype with the future availability of resources and environmental conditions. Changes in the magnitude and frequency of environmental cues such as photoperiod and temperature along latitudes can be used by organisms to predict seasonal changes. While the role of temperature variation on the induction of plastic and seasonal responses is well established, the importance of photoperiod for predicting seasonal changes is less explored. M&M: Here we studied...
Data from: A synthesis of animal-mediated seed dispersal of palms reveals distinct biogeographic differences in species interactionsGabriel Muñoz, Kristian Trøjelsgaard & W. Daniel Kissling
Aim: To synthesize published knowledge on palm-frugivore seed dispersal observations and to test whether broad-scale differences in geographic coverage, diversity, composition and functional structure of plant-animal interactions emerge between biogeographic regions. Location: Neotropics and Afrotropics. Methods: We constructed a meta-network for both regions by aggregating observations of pairwise palm-frugivore interactions from the primary literature. We assessed sampling completeness with accumulation curves and estimated knowledge gaps for individual palm species and geographic units within biogeographic regions....
Data from: Genetic rescue of an endangered domestic animal through outcrossing with closely related breeds: a case study of the Norwegian LundehundAstrid V. Stronen, Elina Salmela, BK Baldursdóttir, P Berg, IS Espelien, Kirsi Järvi, Henrik Jensen, TN Kristensen, Claudia Melis, Tommaso Manenti, Hannes Lohi, Cino Pertoldi & Torsten N. Kristensen
Genetic rescue, outcrossing with individuals from a related population, is used to augment genetic diversity in populations threatened by severe inbreeding and extinction. The endangered Norwegian Lundehund dog (henceforth Lundehund) underwent at least two severe bottlenecks in the 1940s and 1960s that each left only five inbred dogs, and the approximately 1500 dogs remaining world-wide today appear to descend from only two individuals. The Lundehund has a high prevalence of a gastrointestinal disease, to which...
Terrestrial arthropods in the Arctic and Antarctic are exposed to extreme and variable temperatures, and climate change is predicted to be especially pronounced in these regions. Available studies on insect ecophysiology typically focus on the ability of species to tolerate the extreme low temperatures that can occur in these regions, whereas studies investigating species’ plasticity and the importance of evolutionary adaptation to periodically high and increasing temperatures are limited. Here, we provide an overview of...
Data on: contrasting manual and automated assessment of larval body size and thermal stress responses in black soldier flies and housefliesStine Frey Laursen, Laura Skrubbeltrang Hansen, Simon Bahrndorff, Hanne Marie Nielsen, Natasja Krog Noer, David Renault, Goutam Sahana, Jesper Givskov Sørensen & Torsten Nygaard Kristensen
The data files described below contains information on larval body size traits and stress tolerance traits obtained using contrasting methods (manual and automated). The species investigated are black soldier flies (Hermetia illucens) and houseflies (Musca domestica). Larval body size is estimated using manual weighing and imaging analysis software (Noldus EthoVision XT 15.0.1418, Wageningen, the Netherlands). Stress tolerance traits are obtained using manual observations of traditional thermal tolerance assays and by using software for video analysis...
