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)...

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...

Evolutionary gain and loss of a pathological immune response to parasitism

Daniel Bolnick, Jesse Weber, Natalie Steinel, Stephen De Lisle, Lauren Fuess, Foen Peng, Kum Chuan Shim, Brian Lohman & Swapna Subramanian
Parasites impose fitness costs on their hosts. Biologists often assume that natural selection favors infection-resistant hosts. Yet, when the immune response itself is costly, theory suggests selection may instead favor loss of resistance. Intraspecific variation in immune costs are rarely surveyed in a manner that tests evolutionary patterns, and there are few examples of adaptive loss of resistance. Here, we show that when marine threespine stickleback colonized freshwater lakes they gained resistance to the freshwater-associated...

Data from: Predators and temperature shape global body size distributions on macroevolutionary time scales in an old insect order

Erik Svensson, Miguel Gómez-Llano & John Waller
Global body size distributions are shaped by selection pressures arising from biotic and abiotic factors such as temperature, predation and parasitism. Here, we investigated the ecological and evolutionary drivers of global latitudinal size gradients in an old insect order (Odonata; dragonflies and damselflies). Phylogenetic comparative analyses revealed that global size variation of extant taxa is negatively influenced by both regional avian diversity and temperature. Interestingly, fossil data show that the relationship between wing size and...

Axonal degeneration and amyloid pathology predict cognitive decline beyond cortical atrophy

Anna Linnéa Svenningsson, Erik Stomrud, Sebastian Palmqvist, Oskar Hansson & Rik Ossenkoppele
Abstract Background Cortical atrophy is associated with cognitive decline, but the association is not perfect. We aimed to identify factors explaining the discrepancy between the degree of cortical atrophy and cognitive decline in cognitively unimpaired elderly. Methods The discrepancy between atrophy and cognitive decline was measured using the residuals from a linear regression analysis between change in whole brain cortical thickness over time and change in a cognitive composite measure over time in 395 cognitively...

Weak population genetic structure in Eurasian spruce bark beetle over large regional scales in Sweden

Simon J. Ellerstrand, Shruti Choudhury, Kajsa Svensson, Martin N. Andersson, Carsten Kirkeby, Daniel Powell, Fredrik Fredrik Schlyter, Anna Maria Jönsson, Mikkel Brydegaard, Bengt Hansson & Anna Runemark
The Eurasian spruce bark beetle, Ips typographus, is a major pest, capable of killing spruce forests during large population outbreaks. Recorded dispersal distances of individual beetles are typically within hundreds of meters or a few kilometres. However, the connectivity between populations at larger distances and longer time spans and how this is affected by the habitat is less studied, despite its importance for understanding at which distances local outbreaks may spread. Previous population genetic studies...

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.

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...

Core Characteristics of Learning Resource Collectors

Nancy J. Hoebelheinrich, Elizabeth Newbold, Angus Whyte, Maria Johnsson, Kerstin Helbig, Margareta Hellström, Iryna Kuchma & Mijke Jetten
As part of the Education And Training On Handling Of Research Data IG (ETHRD-IG) activities, the Learning Resource Collectors Focus Group studied the evolving landscape of learning resources on RDM topics. As we collected and listed a snapshot of current catalogues or registries of learning resources for review, we realized that a set of core characteristics could describe these types of organisations that would be useful to help people evaluate and understand the resources they...

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...

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...

MHC class II genotype-by-pathogen genotype interaction for infection prevalence in a natural rodent-Borrelia system

Lars Råberg
MHC genes are extraordinarily polymorphic in most taxa. Host-pathogen coevolution driven by negative frequency-dependent selection (NFDS) is one of the main hypotheses for the maintenance of such immunogenetic variation. Here we test a critical but rarely tested assumption of this hypothesis—that MHC alleles affect resistance/susceptibility to a pathogen in a strain-specific way, i.e. that there is a host genotype-by-pathogen genotype interaction. In a field study of bank voles naturally infected with the tick-transmitted bacterium Borrelia...

Timing and synchrony of migration in a freshwater fish: consequences for survival

Kaj Hulthén, Ben Chapman, Anders Nilsson, Lars-Anders Hansson, Christian Skov, Jakob Brodersen & Christer Brönmark
Animal migration is one of the most spectacular and visible behavioural phenomena in nature with profound implications for a range of ecological and evolutionary processes. Successful migration hinges on the ability to exploit temporary resources (e.g. food) and evade threats (e.g. predators) as they arise, and thus the timing of migration is often regarded as a dominant predictor of individual migratory success. However, with the exception of intensively studied taxa (mainly birds), relatively few studies...

Allometric scaling of a superposition eye optimises sensitivity and acuity in large and small hawkmoths

Anna Stöckl, Anna Stöckl, Rebecca Grittner, Gavin Taylor, Christoph Rau, Andrew J. Bodey, Almut Kelber & Emily Baird
Animals vary widely in body size within and across species. This has consequences for the function of organs and body parts in both large and small individuals. How these scale, in relation to body size, reveals evolutionary investment strategies, often resulting in trade-offs between functions. Eyes exemplify these trade-offs, as they are limited by their absolute size in two key performance features: sensitivity and spatial acuity. Due to their size polymorphism, insect compound eyes are...
