Data from: Individual and sex-related patterns of prolonged flights during both day and night by great reed warblers crossing the Mediterranean Sea and Sahara Desert

Gintaras Malmiga, Maja Tarka, Thomas Alerstam, Bengt Hansson & Dennis Hasselquist
A wide variety of the barrier crossing strategies exist among migrating songbirds, ranging from strict nocturnal flights to non-stop flights over a few days. We evaluate barrier crossing strategies in a nocturnally migrating songbird crossing the Mediterranean Sea and the Sahara Desert, the great reed warbler, exploring variation between the sexes and within individuals. We used data from 31 year-round light-level geolocators tracks from 26 individuals (13 males and 13 females), with four individuals tracked...

Heatwave induced invertebrate predation reshapes the plankton community

Nischal Devkota, Romana Salis & Lars-Anders Hansson
Climate change stressors including warming and heatwaves can alter zooplankton composition and dominance patterns in shallow lakes, which can disrupt ecosystem function and curtail ecosystem services. To understand such changes, we performed a mesocosm experiment with controls reflecting the present temperature conditions and a treatment reflecting a future climate change scenario, including heatwaves of 0-8°C. In the future climate scenario, the predatory invertebrate, Mesostoma exerted a strong top-down control particularly on Daphnia, resulting in a...

Nanoscale binding site localization by molecular distance estimation on native cell surfaces using topological image averaging

Pontus Nordenfelt, Vibha Kumra Ahnlide, Johannes Kumra Ahnlide, Sebastian Wrighton & Jason Beech
Antibody binding to cell surface proteins plays a crucial role in immunity and the location of an epitope can altogether determine the immunological outcome of a host-target interaction. Techniques available today for epitope identification are costly, time-consuming, and unsuited for high-throughput analysis. Fast and efficient screening of epitope location can be useful for the development of therapeutic monoclonal antibodies and vaccines. The cellular morphology typically varies, and antibodies often bind heterogeneously across a cell surface,...

Where did the finch go? Insights from radio telemetry of the medium ground finch (Geospiza fortis)

Marc-Olivier Beausoleil, Carlos Camacho, Julio Rabadán-González, Kristen Lalla, Roxanne Richard, Paola Carrion-Avilés, Andrew P. Hendry & Rowan D. H. Barrett
Movement patterns and habitat selection of animals have important implications for ecology and evolution. Darwin's finches are a classic model system for ecological and evolutionary studies, yet their spatial ecology remains poorly studied. We tagged and radio-tracked five (three females, two males) medium ground finches (Geospiza fortis) to examine the feasibility of telemetry for understanding their movement and habitat use. Based on 143 locations collected during a three-week period, we analysed, for the first time,...

Data for: Heritability and parental effects in telomere length in a color polymorphic long-lived bird

Chiara Morosinotto, Staffan Bensch, Maja Tarka & Patrik Karell
Telomere length, an indicator of senescence, has been shown to be heritable but can also be affected by environmental factors, like parental effects. Investigating heritability as well as parental effects and rearing environment can help us to understand the factors affecting offspring telomeres. Moreover, how phenotypic parental traits linked with fitness can impact offspring telomere length is still unclear. A phenotypic marker closely associated with physiological traits and fitness is melanin-based color polymorphism, which in...

Data from: Host sex modulates the energetics of pathogen proliferation and its dependence on environmental resources

Matthew Hall, Lindsey Heffernan, Amanda Pettersen & Stephen Gipson
Sex differences in immunity are predicted to underlie much of the frequently observed sex differences in the prevalence or severity of infection. We propose the additional hypothesis that differences in the ability of males and females to acquire and use resources will also affect how readily a pathogen can convert host energy into transmission stages, thereby contributing to sex differences in infection dynamics. To test this we manipulated the resource environment of male and female...

The contribution of extra-pair paternity to the variation in lifetime and age-specific male reproductive success in a socially monogamous species

Sara Raj Pant
In socially monogamous species, extra-pair paternity (EPP) is predicted to increase variance in male reproductive success beyond that resulting from genetic monogamy, thus increasing the ‘opportunity for selection’ (maximum strength of selection that can act on a trait). This prediction is challenging to investigate in wild populations because lifetime reproduction data are often incomplete. Moreover, age-specific variances in reproductive success have been rarely quantified. We analysed 21 years of near-complete social and genetic reproduction data...

Lake water and sediments chemistry data along with temporal data on environmental drivers

Caroline Björnerås
Increasing iron (Fe) concentrations are found in lakes on a wide geographical scale but exact causes are still debated. The observed trends might result from increased Fe loading from the terrestrial catchment, but also from changes in how Fe distributes between the water column and the sediments. To get a better understanding of the causes we investigated whether there has been any change in the sediment formation of Fe sulfides (FeS) as an Fe sink...

M-values from Illumina EPIC BeadChip DNA methylation analyses on DNA in whole blood for children exposed to PFAS

Karin Engström
Perfluoroalkyl substances (PFASs) are widespread synthetic substances with various adverse health effects. A potential mechanism of toxicity for PFASs is via epigenetic changes, such as DNA methylation. In this exploratory study with school-age children exposed to PFASs through drinking water highly contaminated from firefighting foams, we aimed to investigate whether exposure to PFASs was associated with alteration in DNA methylation and epigenetic age acceleration. Sixty-three children aged 7–11 years from the Ronneby Biomarker Cohort (Sweden)...

Connie Y. Kot, Susanne Åkesson, Joanna Alfaro-Shigueto, Diego Fernando Amorocho Llanos, Marina Antonopoulou, George H. Balazs, Warren R. Baverstock, Janice M. Blumenthal, Annette C. Broderick, Ignacio Bruno, Ali Fuat Canbolat, Paolo Casale, Daniel Cejudo, Michael S. Coyne, Corrie Curtice, Sarah DeLand, Andrew DiMatteo, Kara Dodge, Daniel C. Dunn, Nicole Esteban, Angela Formia, Mariana M. P. B. Fuentes, Ei Fujioka, Julie Garnier, Matthew H. Godfrey … & Patrick N. Halpin
Aim: Understanding the spatial ecology of animal movements is a critical element in conserving long-lived, highly mobile marine species. Analysing networks developed from movements of six sea turtle species reveals marine connectivity and can help prioritize conservation efforts. Location: Global. Methods: We collated telemetry data from 1,235 individuals and reviewed the literature to determine our dataset’s representativeness. We used the telemetry data to develop spatial networks at different scales to examine areas, connections, and their...

Data from: Turnover and nestedness drive plant diversity benefits of organic farming from local to landscape scales

Romain Carrié
Biodiversity-benefits of organic farming have mostly been documented at the field scale. However, these benefits from organic farming to species diversity may not propagate to larger scales, because variation in the management of different crop types and semi-natural habitats in conventional farms might allow species to cope with intensive crop management. We studied flowering plant communities using a spatially replicated design in different habitats (cereal, ley and semi-natural grasslands) in organic and conventional farms, distributed...

Data for fitness analyses used in: Environmentally-induced DNA methylation is inherited across generations in water fleas (Daphnia magna)

Reinder Radersma, Alexander Hegg, Nathalie Feiner & Tobias Uller
Data of fitness effects of environmental stressors on Daphnia magna over multiple generations. Ages of first and second reproduction, and sizes of first and second brood were measured and used to calculate replacement rate. This data is part of a study on whole-genome bisulphate sequencing on individual Daphnia magna to assess whether environmentally-induced DNA methylation can persist for up to four generations.

Data from: Traits across trophic levels interact to influence parasitoid establishment in biological control releases

Benjamin Jarrett & Marianna Szűcs
A central goal in ecology is to predict what governs a species’ ability to establish in a new environment. One mechanism driving establishment success is individual species’ traits, but the role of trait combinations among interacting species across different trophic levels are less clear. Deliberate or accidental species additions to existing communities provide opportunities to study larger scale patterns of establishment success. Biological control introductions are especially valuable because they contain data on both the...

The genomic architecture of the passerine MHC region: high repeat content and contrasting evolutionary histories of single copy and tandemly duplicated MHC genes

Helena Westerdahl
The Major Histocompatibility Complex (MHC) is of central importance to the immune system, and an optimal MHC diversity is believed to maximize pathogen elimination. Birds show substantial variation in MHC diversity, ranging from few genes in most bird orders to very many genes in passerines. Our understanding of the evolutionary trajectories of the MHC in passerines is hampered by lack of data on genomic organization. Therefore, we assemble and annotate the MHC genomic region of...

Data from: Evaluating staging habitat quality to advance the conservation of a declining migratory shorebird, Red Knot Calidris canutus

Tong Mu, Shangxiao Cai, Hebo Peng, Chris J. Hassell, Adrian Boyle, Zhengwang Zhang, Theunis Piersma & David Wilcove
Identifying where and when population “bottlenecks” occur is critical to the conservation of migratory species, many of which are declining precipitously worldwide. Especially challenging is the evaluation of changes to staging sites. These sites are indispensable links in the migratory cycle but are typically used only briefly. We devised a field-based approach to assess the quality and carrying capacity of a critical staging site in Nanpu, China, for the declining, migratory Red Knot (Calidris canutus...

A single locus regulates a female-limited color pattern polymorphism in a reptile

Nathalie Feiner
Animal coloration is often expressed in periodic patterns that can arise from differential cell migration, yet how these processes are regulated remains elusive. We show that a female-limited polymorphism in dorsal patterning (diamond/chevron) in the brown anole is controlled by a single Mendelian locus. This locus contains the gene CCDC170 that is adjacent to, and co-expressed with, the Estrogen receptor-1 gene, explaining why the polymorphism is female-limited. CCDC170 is an organizer of the Golgi-microtubule network...

Phenotypic plasticity is aligned with phenological adaptation on micro- and macroevolutionary timescales

Stephen De Lisle, Maarit Mäenpää & Erik Svensson
In seasonally-variable environments, phenotypic plasticity in phenology may be critical for adaptation to fluctuating environmental conditions. Using an 18-generation longitudinal dataset from natural damselfly populations, we show that phenology has strongly advanced. Individual fitness data suggest this is likely an adaptive response towards a temperature-dependent optimum. A laboratory experiment revealed that developmental plasticity qualitatively matches the temperature-dependence of selection, partially explaining observed advance in phenology. Expanding our analysis to the macroevolutionary level, we use a...

Predictors of genomic differentiation within a hybrid taxon

Angelica Cuevas, Fabrice Eroukhmanoff, Mark Ravinet, Glenn-Peter Sætre & Anna Runemark
Hybridization is increasingly recognized as an important evolutionary force. Novel genetic methods now enable us to address how the genomes of parental species are combined in hybrid lineages. However, we still do not know the relative importance of admixed proportions, genome architecture and local selection in shaping hybrid genomes. Here, we take advantage of the genetically divergent island populations of Italian sparrow on Crete, Corsica and Sicily to investigate the predictors of genomic variation within...

Algal growth, bumblebee colony and individual development, bee behavior and yield of oilseed rape under a trophic cascade and extreme weather

Björn Klatt, Bethany Pudifoot, Pablo Urrutia-Cordero, Henrik Smith & Christian Alsterberg
Trophic cascades in the aquatic environment constitute important mechanisms for improving water quality. However, how the presence or non-presence of these trophic cascades may affect interactions across the aquatic-terrestrial interface remains poorly investigated. Pollinators such as bees may be especially vulnerable to changes in water resource quality induced by trophic cascades. Understanding how aquatic trophic cascades affect bees and pollination becomes even more pressing under ongoing climate change due to increased physiological demands for water...
