Data from: Oxidative damage to lipids is rapidly reduced during migratory stopovers

Cas Eikenaar, Erica Winslott, Sven Hessler & Caroline Isaksson
Most migrating birds need to stopover in between flights in order to refuel. Lately, additional purposes of stopover have been suggested, including physiological recovery from metabolically demanding migratory flight. One apparently unavoidable, but harmful physiological effect of migratory flight is increased oxidative damage to lipids and proteins. We here, for the first time, tested whether migrating birds are able to reduce their oxidative damage during stopover. To be able to collect longitudinal data on a...

Data offspring performance following two-donor crosses at different floral stages and with different competitor types in greenhouse studies of Collinsia heterophylla

Åsa Lankinen, Josefin Madjidian, Henrik G. Smith & Stefan Andersson
Data on two offspring performance traits (seeds per capsule and flower number) in greenhouse studies of Collinsia heterophylla to investigate indirect benefits of mate choice. We performed two-donor pollinations during successive floral stages and with different competitor types (outcross and self) to assess how stigma receptivity and two pollen traits known to affect siring success influence offspring performance. We also investigated the link between seed production in mothers and offspring as an indication of heritability...

Data from: More than meets the eye: predator-induced pupil size plasticity in a teleost fish

Jerker Vinterstare, Kaj Hulthén, Dan Nilsson, Anders Nilsson & Christer Brönmark
1. Most animals are visually oriented, and their eyes provide their “window to the world”. Eye size correlates positively with visual performance, because larger eyes can house larger pupils that increase photon catch and contrast discrimination, particularly under dim light, which have positive effects on behaviours that enhance fitness, including predator avoidance and foraging. 2. Recent studies have linked predation risk to selection for larger eyes and pupils, and such changes should be of importance...

Down feather morphology reflects adaptation to habitat and thermal conditions across the avian phylogeny

Peter Laszlo Pap, Gergely Osváth, Timea Daubner, Andreas Nord & Orsolya Vincze
Down feathers are the first feather types that appear in both the phylogenetic and the ontogenetic history of birds. Although it is widely acknowledged that the primary function of downy elements is insulation, little is known about the interspecific variability in the structural morphology of these feathers, and the environmental factors that have influenced their evolution. Here, we collected samples of down and afterfeathers from 156 bird species and measured key morphological characters that define...

Resistance-recovery tradeoff of soil microbial communities under altered rain regimes: An experimental test across European agroecosystems

Gabin Piton, Arnaud Foulquier, Laura B. Martinez-García, Nicolas Legay, Lijbert Brussaard, Katarina Hedlund, Pedro Martins Da Silva, Eduardo Nascimento, Filipa Reis, José Paulo Sousa, Jean Christophe Clement & Gerlinde De Deyn
With the increased occurrence of climate extremes, there is an urgent need to better understand how management strategies affect the capacity of the soil microbial community to maintain its ecosystem functions (e.g. nutrient cycling). To address this issue, intact monoliths were extracted from conventional and ecological managed grasslands in three countries across Europe and exposed under common air condition (temperature and moisture) to one of three altered rain regimes (dry, wet and intermittent wet/dry) as...

Telomere length in relation to colour polymorphism across life stages in the tawny owl

Chiara Morosinotto, Staffan Bensch & Patrik Karell
Abstract of the paper: Telomere erosion has been proposed to be tightly associated with senescence, environmental stressors and life history trade-offs. How telomere dynamics vary across life stages and especially in relation to (heritable) phenotypic traits is still unclear. The tawny owl Strix aluco display a highly heritable melanin-based colour polymorphism, a grey and a brown morph, linked to several fitness traits including morph-specific telomere dynamics. As adults, brown tawny owls have shorter relative telomere...

Accelerated landing in a stingless bee and its unexpected benefits for traffic congestion

Pierre Tichit, Isabel Alves-Dos-Santos, Marie Dacke & Emily Baird
To land, flying animals must simultaneously reduce speed and control their path to the target. While the control of approach speed has been studied in many different animals, little is known about the effect of target size on landing, particularly for small targets that require precise trajectory control. To begin to explore this, we recorded the stingless bee Scaptotrigona depilis landing on their natural hive entrance – a narrow wax tube built by the bees...

Accelerated landings in stingless bees are triggered by visual threshold cues

Pierre Tichit, Emily Baird, Marie Dacke & Isabel Alves-Dos-Santos
Most flying animals rely primarily on visual cues to coordinate and control their trajectory when landing. Studies of visually-guided landing typically involve animals that decrease their speed before touchdown. Here, we investigate the control strategy of the stingless bee Scaptotrigona depilis, which instead accelerates when landing on its narrow hive entrance. By presenting artificial targets that resemble the entrance at different locations on the hive, we show that these accelerated landings are triggered by visual...

Supplementary tables S5, S7, S9, S10, original protein models fasta files used for alignments, aligned and manually curated protein modes files used for phylogenies (PHYLIP format), and phylogenetic trees of plant cell wall decomposition gene families from 44 basidiomycete genomes (.tre files)

Dimitrios Floudas, Johan Bentzer, Dag Ahren, Tomas Johansson, Per Persson & Anders Tunlid
Litter-decomposing Agaricales play key role in terrestrial carbon cycling, but little is known about their decomposition mechanisms. We assembled datasets of 42 gene families involved in plant-cell-wall decomposition from seven newly sequenced litter decomposers and 35 other Agaricomycotina members, mostly white-rot and brown-rot species. Using sequence similarity and phylogenetics, we split the families into phylogroups and compared their gene composition across nutritional strategies. Subsequently, we used Raman spectroscopy to examine the ability of litter decomposers,...

Data from: Male-male competition causes parasite-mediated sexual selection for local adaptation

Miguel Gomez-Llano, Aaditya Narasimhan & Erik Svensson
Sexual selection has been suggested to accelerate local adaptation and promote evolutionary rescue through several ecological and genetic mechanisms. Condition-dependent sexual selection has mainly been studied in laboratory settings while data from natural populations are lacking. One ecological factor that can cause condition-dependent sexual selection is parasitism. Here, we quantified ectoparasite load (Arrenurus water mites) in a natural population of the common bluetail damselfly (Ischnura elegans) over 15 years. We quantified the strength of sexual...

Whole-genome analysis across ten songbird families within Sylvioidea reveals a novel autosome–sex chromosome fusion

Hanna Sigeman, Suvi Ponnikas & Bengt Hansson
Sex chromosomes in birds have long been considered to be extremely stable. However, this notion has lately been challenged by findings of independent autosome–sex chromosome fusions within songbirds, several of which occur within a single clade, the superfamily Sylvioidea. To understand what ecological and evolutionary processes drive changes in sex chromosome systems, we need complete descriptions of sex chromosome diversity across taxonomic groups. Here, we characterize the sex chromosome systems across Sylvioidea using whole-genome data...

Dramatic decline of northern bat Eptesicus nilssonii in Sweden over 30 years

Jens Rydell, Marcus Elfstrom & Sonia Sanchez-Navarro
We monitored northern bat Eptesicus nilssonii (Keyserling & Blasius, 1839) acoustically along a 27 km road transect at weekly intervals in 1988, 1989, and 1990, and again in 2016 and 2017. The methodology of data collection and the transect were the same throughout, except that the insect-attracting mercury-vapour streetlights along parts of the road were replaced by sodium lights between the two survey periods. Counts along sections of the transect with and without streetlights were...

A genome-wide linkage map for the house sparrow (Passer domesticus) provides insights into the evolutionary history of the avian genome

Ingerid Hagen, Sigbjørn Lien, Anna Billing, Tore O. Elgvin, Cassandra Trier, Alina K. Niskanen, Maja Tarka, Jon Slate, Glenn-Peter Sætre & Henrik Jensen
The house sparrow is an important model species for studying physiological, ecological and evolutionary processes in wild populations. Here, we present a medium density, genome wide linkage map for house sparrow (Passer domesticus) that has aided the assembly of the house sparrow reference genome, and that will provide an important resource for ongoing mapping of genes controlling important traits in the ecology and evolution of this species. Using a custom house sparrow 10K iSelect Illumina...

Biomarkers in urinary tract infections – which ones are suitable for diagnostics and follow-up?

József Horváth, Björn Wullt, Kurt G. Naber & Béla Köves
Introduction: Urinary tract infections (UTIs) are one of the most common infections worldwide. Under special circumstances, clinicians must rely on laboratory findings, which might have a weak predicting value, misguiding the practitioners and leading to incorrect diagnosis and overuse of antibiotics. Therefore, there is an urgent need for reliable biomarkers in UTIs. Methods: We performed a literature search for biomarkers used in UTIs from January 1999 until May 2020. We used “urinary tract infection” and...

Butterflies fly using efficient propulsive clap mechanism owing to flexible wings

Christoffer Johansson & Per Henningsson
Butterflies look like no other flying animal, with unusually short, broad and large wings relative to their body size. Previous studies have suggested butterflies use several unsteady aerodynamic mechanisms to boost force production with upstroke wing clap being a prominent feature. When the wings clap together at the end of upstroke the air between the wings is pressed out, creating a jet, pushing the animal in the opposite direction. Although viewed, for the last 50...

Balancing selection in Pattern Recognition Receptor signalling pathways is associated with gene function and pleiotropy in a wild rodent

Lars Råberg, Max Lundberg, Xiuqin Zhong, Anna Konrad & Remi-André Olsen
Pathogen-mediated balancing selection is commonly considered to play an important role in the maintenance of genetic diversity, in particular in immune genes. However, there has not been any systematic analysis of what factors influence which immune genes are the targets of such selection. To address this, we here focus on Pattern Recognition Receptor (PRR) signalling pathways, which play a key role in innate immunity. We used whole-genome resequencing data from a population of bank voles...

Data from: Comparison of spleen transcriptomes of two wild rodent species reveals differences in the immune response against Borrelia afzelii

Xiuqin Zhong, Max Lundberg & Lars Råberg
Different host species often differ considerably in susceptibility to a given pathogen, but the causes of such differences are rarely known. The natural hosts of the tick-transmitted bacterium Borrelia afzelii, which is one of causative agents of Lyme borreliosis in humans, include a variety of small mammals like voles and mice. Previous studies have shown that B. afzelii-infected bank voles (Myodes glareolus) have about ten times higher bacterial load than infected yellow-necked mice (Apodemus flavicollis),...

Don’t judge a lizard by its colour: no evidence for differential socio-sexual behaviour and space use in the colour morphs of the European common wall lizard (Podarcis muralis)

Javier Abalos, Guillem Pérez I De Lanuza, Alicia Bartolomé, Océane Liehrmann, Hanna Laakkonen, Fabien Aubret, Tobias Uller, Pau Carazo & Enrique Font
Explaining the evolutionary origin and maintenance of colour polymorphisms is a major challenge in evolutionary biology. Such polymorphisms are commonly thought to reflect the existence of alternative behavioural or life-history strategies under negative frequency-dependent selection. The European common wall lizard Podarcis muralis exhibits a striking ventral colour polymorphism that has been intensely studied and is often assumed to reflect alternative reproductive strategies, similar to the iconic “rock-paper-scissors” system described in the North American lizard Uta...

A study of tactical and sexual dimorphism in cognition with insights for sexual conflict

Hannah Griebling, Oscar Rios-Cardenas, Jessica Abbott & Molly Morris
The sexes may have different optima in cognitive traits due to differences in life history strategies and the expense of investing in metabolically costly brain tissue. However, given genetic correlations, each sex could be constrained from reaching its cognitive optimum due to intralocus sexual conflict. We compared learning performance of two male alternative reproductive tactics and females from known genotypes (both sire and dam) in the livebearing fish Xiphophorus multilineatus. We predicted that females’ learning...

Effects of back‐mounted biologgers on condition, diving and flight performance in a breeding seabird

Tom J. Evans, Rebecca C. Young, Hannah Watson, Olof Olsson & Susanne Åkesson
Biologging devices are providing detailed insights into the behaviour and movement of animals in their natural environments. It is usually assumed that this method of gathering data does not impact on the behaviour observed. However, potential negative effects on birds have rarely been investigated before field‐based studies are initiated. Seabirds which both fly and use pursuit diving may be particularly sensitive to increases in drag and load resulting from carrying biologging devices. We studied chick‐rearing...

The search for sexually antagonistic genes: practical insights from studies of local adaptation and statistical genomics

Filip Ruzicka, Ludovic Dutoit, Peter Czuppon, Crispin Y. Jordan, Xiang‐Yi Li, Colin Olito, Homa Papoli Yazdi, Tim Connallon, Erik Svensson & Anna Runemark
Sexually antagonistic (SA) genetic variation—in which alleles favored in one sex are disfavored in the other—is predicted to be common and has been documented in several animal and plant populations, yet we currently know little about its pervasiveness among species or its population genetic basis. Recent applications of genomics in studies of SA genetic variation have highlighted considerable methodological challenges to the identification and characterization of SA genes, raising questions about the feasibility of genomic...

Innate preference hierarchies coupled with adult experience, rather than larval imprinting or transgenerational acclimation, determine host plant use in Pieris rapae

Hampus Petrén, Gabriele Gloder, Diana Posledovich, Christer Wiklund & Magne Friberg
The evolution of host range drives diversification in phytophagous insects, and understanding the female oviposition choices is pivotal for understanding host specialization. One controversial mechanism for female host choice is Hopkins’ host selection principle, where females are predicted to increase their preference for the host species they were feeding upon as larvae. A recent hypothesis posits that such larval imprinting is especially adaptive in combination with anticipatory transgenerational acclimation, so that females both allocate and...

Drought legacy affects microbial community trait distributions related to moisture along a savannah grassland precipitation gradient

Ainara Leizeaga, Lettice C. Hicks, Lokeshwaran Manoharan, Christine V. Hawkes & Johannes Rousk
Ecosystem models commonly use stable-state assumptions to predict responses of soil microbial functions to environmental change. However, past climatic conditions can shape microbial functional responses resulting in a “legacy effect”. For instance, exposure to drier conditions in the field may shape how soil microbial communities respond to subsequent drought and drying and rewetting events. We investigated microbial tolerance to low moisture levels (“resistance”) and ability to recover after a drying and rewetting (DRW) perturbation (“resilience”)...

Caught in a bottleneck: Habitat loss for woolly mammoths in central North America and the ice-free corridor during the last deglaciation

Yue Wang, Chris Widga, Russell Graham, Jenny McGuire, Warren Porter, David Wårlind & John Williams
The dataset is to describe the habitat structure and bioenergetic characteristics of woolly mammoths (Mammuthus primigenius) in North America during the last deglaciation between 15 and 10 ka. The habitat structure includes fractional woody cover (FWC) and net primary productivity (NPP) for 20 plant functional types (PFTs). NPP is based on the dynamic vegetation model LPJ-GUESS (LPJG). FWC is based on LPJ-GUESS and fossil pollen records in the Neotoma Paleoecology Database. The bioenergetic characteristics of...

Nocturnal bees feed on diurnal leftovers and pay the price of day–night lifestyle transition

Hema Somanathan, Shivani Krishna, Elsa Mini Jos, Vishwas Gowda, Almut Kelber & Renee Borges
Bees exemplify flights under bright sunlight. A few species across bee families have evolved nocturnality, displaying remarkable adaptations to overcome limitations of their daylight-suited apposition eyes. Phase inversion to nocturnality in a minority of bees that co-exist with diurnal bees provide a unique opportunity to study ecological benefits that mediate total temporal niche shifts. While floral traits and sensory modalities associated with the evolution of classical nocturnal pollination syndromes, e.g. by bats and moths, are...
