Towards a stable global Noctuidae (Lepidoptera) taxonomy

Kevin Keegan, Jadranka Rota, Reza Zahiri, Alberto Zilli, Niklas Wahlberg, B. Christian Schmidt, J. Donald Lafontaine, Paul Goldstein & David Wagner
The family Noctuidae is one of the world’s most diverse, ecologically successful, and economically important animal lineages; with over 12,000 species in ~1150 genera. We inferred a phylogeny based on eight protein-coding genes (>6,400 base pairs) for the global fauna, greatly expanding upon previous attempts to stabilize the higher classification of Noctuidae by sampling 70 of the 76 widely recognized family-group taxa: 20 of the 21 subfamilies, 32 of the 35 tribes, and 18 of...

Data from: Climate shapes the geographic distribution and introgressive spread of colour ornamentation in common wall lizards

Maravillas Ruiz Minano, Geoffrey While, Weizhao Yang, Christopher Burridge, Roberto Sacchi, Marco Zuffi, Stefano Scali, Daniele Salvi & Tobias Uller
Climate can exert an effect on the strength of sexual selection, but empirical evidence is limited. Here, we tested if climate predicts the geographic distribution and introgressive spread of sexually selected male colour ornamentation across 114 populations of the common wall lizard, Podarcis muralis. Colouration was highly structured across the landscape, and did not reflect genetic differentiation. Instead, colour ornamentation was consistently exaggerated in hot and dry environments, suggesting that climate-driven selection maintains geographic variation...

Data from: A molecular phylogeny of forktail damselflies (genus Ischnura) reveals a dynamic macroevolutionary history of female colour polymorphisms

Rachel Blow, Beatriz Willink & Erik Svensson
Colour polymorphisms are popular study systems among biologists interested in evolutionary dynamics, genomics, sexual selection and sexual conflict. In many damselflies, such as in the globally distributed genus Ischnura (forktails), female colour polymorphisms occur in some species. Female-polymorphic species contain two or three female morphs, one of which is male-coloured (androchrome or male mimic) and co-exists with sexually dimorphic (heterochrome) females. These female colour polymorphisms are considered to be maintained by frequency-dependent sexual conflict, but...

Why don't all animals avoid inbreeding?

Victoria Pike, Charlie Cornwallis & Ashleigh Griffin
Individuals are expected to avoid mating with relatives as inbreeding can reduce offspring fitness, a phenomenon known as inbreeding depression. This has led to the widespread assumption that selection will favour individuals that avoid mating with relatives. However, the strength of inbreeding avoidance is variable across species and there are numerous cases where related mates are not avoided. Here we test if the frequency that related males and females encounter each other explains variation in...

Genetics of quantitative traits with dominance under stabilizing and directional selection in partially selfing species

Josselin CLO & Øystein Opedal
Recurrent self-fertilization is thought to lead to reduced adaptive potential by decreasing the genetic diversity of populations, thus leading selfing lineages down an evolutionary ‘blind alley’. Though well supported theoretically, empirical support for reduced adaptability in selfing species is limited. One limitation of classical theoretical models is that they assume pure additivity of the fitness-related traits that are under stabilizing selection, despite ample evidence that quantitative traits are subject to dominance. Here we relax this...

Exposure to artificial light at night alters innate immune response in wild great tit nestlings

Ann-Kathrin Ziegler, Watson Hannah, Hegemann Arne, Meitern Richard, Canoine Virginie, Nilsson Jan-Åke & Isaksson Caroline
The large-scale impact of urbanization on wildlife is rather well documented; however, the mechanisms underlying the effects of urban environments on animal physiology and behaviour are still poorly understood. Here, we focused on one major urban pollutant - artificial light at night (ALAN) - and its effects on the capacity to mount an innate immune response in wild great tit (Parus major) nestlings. Exposure to ALAN alters circadian rhythms of physiological processes, by disrupting the...

Daphnia magna trade-off safety from UV radiation for food

Marcus Lee & Lars-Anders Hansson
Research on diel vertical migration (DVM) is generally conducted at the population level, whereas few studies have focused on how individual animals behaviorally respond to threats when also having access to foraging opportunities. We utilized a 3-D tracking platform to record the swimming behavior of Daphnia magna exposed to ultraviolet radiation (UVR) in the presence or absence of a food patch. We analyzed the vertical position of individuals before and during UVR exposure and found...

A field experiment reveals seasonal variation in the Daphnia gut microbiome

Alexander Hegg, Reinder Radersma & Tobias Uller
The gut microbiome is increasingly recognized for its impact on host fitness, but it remains poorly understood how naturally variable environments influence gut microbiome diversity and composition. We studied changes in the gut microbiome of ten genotypes of water fleas (Daphnia magna) in submerged mesocosm enclosures in a eutrophic lake over a period of 16 weeks, from early summer to autumn. The microbial diversity increased when Daphnia were reintroduced from the laboratory to the lake,...

Data from: Reindeer control over subarctic treeline alters soil fungal communities with potential consequences for soil carbon storage

Henni Ylänne, Rieke L. Madsen, Carles Castaño, Daniel B. Metcalfe & Karina E. Clemmensen
Here we present the data and R script from “Reindeer control over subarctic treeline alters soil fungal communities with potential consequences for soil carbon storage” by Henni Ylänne, Rieke L. Madsen, Carles Castaño, Daniel B. Metcalfe and Karina E. Clemmensen (Global Change Biology, 2021). In this study we reported the impacts of grazing regime and mountain birch vicinity on the abundance, diversity and community composition of the soil fungal community, and explored how the soil...

Selection data: Reproductive success and morphology

Melissa Liotta, Jessica Abbott, Molly Morris & Oscar Rios-Cardenas
Alternative reproductive tactics (ARTs) have provided valuable insights into how sexual selection and life history tradeoffs can lead to variation within a sex. However, the possibility that tactics may constrain evolution through intralocus tactical conflict is rarely considered. In addition, when intralocus conflict has been considered, the focus has often been on the genetic correlations between the ARTs, while evidence that the ARTs have different optima for associated traits and that at least one of...

Cross-reactivity of antibody responses to Borrelia afzelii OspC

Lars Råberg, Mehrnaz Nouri, Neus Latorre Margalef & Agnieszka Czopek
The tick-transmitted bacterium Borrelia afzelii consists of a number of antigenically different strains ¾ often defined by outer surface protein C (OspC) genotype ¾ that coexist at stable frequencies in host populations. To investigate how host antibody responses affect strain coexistence, we measured antibody cross-reactivity to three different OspC types (OspC 2, 3 and 9) in three different strains of laboratory mice (BALB/c, C3H and C57BL/6). The extent of cross-reactivity differed between mouse strains, being...

Data from: An international, multi-stakeholder survey about metadata awareness, knowledge, and use in scholarly communications

Laura Paglione, Kathryn Kaiser, Michelle Urberg, Maria Johnsson, Jennifer Kemp & Alice Meadows
The Metadata 2020 initiative is an ongoing effort to bring various scholarly communications stakeholder groups together to promote principles and standards of practice to improve the quality of metadata. To understand the perspectives and practices of the main stakeholder groups (librarians, publishers, researchers and repository managers) regarding metadata, the Metadata 2020 Researcher Communications Project Group conducted a survey in the summer of 2019. The survey content was generated by representatives from the stakeholder groups who...

Detecting purging of inbreeding depression by a slow rate of inbreeding for various traits: the impact of environmental and experimental conditions

Mads Fristrup Schou, Jørgen Bundgaard, Volker Loeschcke &
Inbreeding depression (ID) has since long been recognized as a significant factor in evolutionary biology. It is mainly the consequence of (partially) recessive deleterious mutations maintained by mutation-selection balance in large random mating populations. When population size is reduced, recessive alleles are increasingly found in homozygous condition due to drift and inbreeding and become more prone to selection. Particularly at slow rates of drift and inbreeding, selection will be more effective in purging such alleles,...

Data from: Male and female reproductive fitness costs of an immune response in natural populations

Stephen De Lisle & Daniel Bolnick
Parasites can mediate host fitness both directly, via effects on survival and reproduction, or indirectly by inducing host immune defense with costly side-effects. The evolution of immune defense is determined by a complex interplay of costs and benefits of parasite infection and immune response, all of which may differ for male and female hosts in sexual lineages. Here, we examine fitness costs associated with an inducible immune defense in a fish-cestode host-parasite system. Cestode infection...

Hovering flight in hummingbird hawkmoths: Kinematics, wake dynamics and aerodynamic power

Kajsa Warfvinge, Christoffer Johansson & Anders Hedenström
Hovering insects are divided into two categories: ‘normal’ hoverers that move the wing symmetrically in a horizontal stroke plane, and those with an inclined stroke plane. Normal hoverers have been suggested to support their weight during both downstroke and upstroke, shedding vortex rings each half-stroke. Insects with an inclined stroke plane should, according to theory, produce flight forces only during downstroke, and only generate one set of vortices. The type of hovering is thus linked...

Evolutionary tradeoffs between male secondary sexual traits revealed by a phylogeny of the hyperdiverse tribe Eumaeini (Lepidoptera: Lycaenidae)

Wendy A. Valencia-Montoya, Tiago B. Quental, João Filipe R. Tonini, Gerard Talavera, James D. Crall, Gerardo Lamas, Robert C. Busby, Ana Paula S. Carvalho, Ana B. Morais, Nicolás Oliveira Mega, Helena Piccoli Romanowski, Marjorie A. Liénard, Shayla Salzman, Melissa R. L. Whitaker, Akito Y. Kawahara, David J. Lohman, Robert K. Robbins & Naomi E. Pierce
Male butterflies in the hyperdiverse tribe Eumaeini possess an unusually complex and diverse repertoire of secondary sexual characteristics involved in pheromone production and dissemination. Maintaining multiple sexually selected traits is likely to be metabolically costly, potentially resulting in trade-offs in the evolution of male signals. However, a phylogenetic framework to test hypotheses regarding the evolution and maintenance of male sexual traits in Eumaeini has been lacking. Here, we infer a comprehensive, time-calibrated phylogeny from 379...

Data for: Flying through gaps – How does a bird deal with the problem and what costs are there?

Per Henningsson
Animals flying in the wild often show remarkable abilities to negotiate obstacles and narrow openings in complex environments. Impressive as these abilities are, this must result in costs in terms of impaired flight performance. In this study, I used a budgerigar as model for studying these costs. The bird was filmed in stereo when flying through a wide range of gap widths from well above wingspan down to a mere 1/4 of wingspan. 3D flight...

Data from: Extreme altitudes during diurnal flights in a nocturnal songbird migrant

Sissel Sjöberg, Gintaras Malmiga, Andreas Nord, Arne Andersson, Johan Bäckman, Maja Tarka, Mikkel Willemoes, Kasper Thorup, Bengt Hansson, Thomas Alerstam & Dennis Hasselquist
Billions of nocturnally migrating songbirds fly across oceans and deserts on their annual journeys. Using multisensor dataloggers, we show that great reed warblers (Acrocephalus arundinaceus) regularly prolong their otherwise strictly nocturnal flights into daytime when crossing the Mediterranean Sea and the Sahara Desert. Intriguingly, when prolonging their flights, they climbed steeply at dawn, from mean 2,394 m asl to reach extreme cruising altitudes (mean 5,367 m asl, max 6,267 m asl) during daytime flights. This...

Fish resist temptation from junk food: State-dependent diet choice in reproductive Atlantic cod (Gadus morhua) facing seasonal fluxes of lipid-rich prey

Mikael Van Deurs, Anders Persson & Christian Jorgensen
In ecological sciences, animal diets are often simplified to “resources” or “caloric quantities”. However, in the present study, we investigated the optimal foraging strategy of Atlantic cod (Gadus morhua) when both macro- and micro-nutritional requirements are accounted for. Proteins cannot be synthesized from fatty acids, so the proteins for gonad development must come from other dietary sources. In addition, micronutrients are required in smaller quantities. For example, for cod, arachidonic acid (ARA) acts as a...

Data from: Variation in predation regime drives sex-specific differences in mosquitofish foraging behaviour

Varpu Pärssinen, Kaj Hulthén, Christer Brönmark, Gustaf Ekelund Ugge, Raphael Gollnisch, Simon David Herzog, Nan Hu, Marcus Lee, Yongcui Sha, Martin Škerlep, Jerker Vinterstare, R. Brian Langerhans, P. Anders Nilsson, Caroline Björnerås, Lars-Anders Hansson, Emma Johansson, Karin Rengefors & Huan Zhang
Predation is a well-studied driver of ecological selection on prey traits, which frequently drives divergence in anti-predator performance across environments that vary in predation risk. However, predation also alters prey mortality regimes, where low predation risk often results in higher prey densities and consequently higher intensities of intraspecific resource competition. In addition, predation risk alters the foraging context, as acquiring food can be risky in the presence of predators. Thus, different predation regimes can drive...

Wild bees and hoverflies respond differently to urbanisation, human population density and urban form

Anna Persson, Johan Ekroos, Peter Olsson & Henrik Smith
While urbanisation contributes to global biodiversity declines, flower-rich urban habitats may provide beneficial pollinator habitats. We investigated the potential of urban residential areas to contribute to pollinator diversity by analysing wild bee and hoverfly species richness and composition of species assemblages of summer-active species, sampled in 53 gardens across urban and rural landscapes of Malmö, the regional capital of Sweden’s southernmost county. Species richness differed between urban and rural gardens, and between four urban residential...

Latitudinal clines in sexual selection, sexual size dimorphism, and sex-specific genetic dispersal during a poleward range expansion

Rachael Dudaniec, Alexander Carey, Erik Svensson, Bengt Hansson, Chuan Ji Yong & Lesley Lancaster
Range expansions can be shaped by sex differences in behaviours and other phenotypic traits affecting dispersal and reproduction. Here, we investigate sex differences in morphology, behaviour and genomic population differentiation along a climate-mediated range expansion in the common bluetail damselfly Ischnura elegans in northern Europe. We sampled 65 sites along a 583 km gradient spanning the I. elegans range in Sweden and quantified latitudinal gradients in site relative abundance, sex ratio and sex-specific shifts in...

Data from: Wintering bird communities are tracking climate change faster than breeding communities

Aleksi Lehikoinen, Åke Lindström, Andrea Santangeli, Päivi Sirkiä, Lluis Brotons, Vincent Devictor, Jaanus Elts, Ruud P. B. Fobben, Henning Heldbjerg, Sergi Herrando, Marc Herremans, Marie-Anne R. Hudson, Frederic Jiguet, Alison Johnston, Romain Lorrilliere, Emma-Liina Marjakangas, Nicole L. Michel, Charlotte M. Moshøj, Renno Nellis, Jean-Yves Paquet, Adam C. Smith, Tibor Szep & Chris Van Turnhout
1. Global climate change is driving species’ distributions towards the poles and mountain tops during both non-breeding and breeding seasons, leading to changes in the composition of natural communities. However, the degree of season differences in climate-driven community shifts has not been thoroughly investigated at large spatial scales. 2. We compared the rates of change in the community composition during both winter (non-breeding season) and summer (breeding) and their relation to temperature changes. 3. Based...

Fitness cost from fluctuating ultraviolet radiation in Daphnia magna

Franca Stábile, Christer Brőnmark, Lars-Anders Hansson & Marcus Lee
Solar ultraviolet radiation (UVR) is an important environmental threat for organisms in aquatic systems, but its temporally variable nature makes the understanding of its effects ambiguous. The aim of our study was to assess potential fitness costs associated with fluctuating UVR in the aquatic zooplankter Daphnia magna. We investigated individual survival, reproduction and behaviour when exposed to different UVR treatments. Individuals exposed to fluctuating UVR, resembling natural variations in cloud cover, had the lowest fitness...
