Flowering synchrony drives reproductive success in a wind-pollinated tree

Michał Bogdziewicz, Mario Pesendorfer, Elizabeth Crone, Carlos Pérez-Izquierdo & Raul Bonal
Synchronized and quasi-periodic production of seeds by plant populations, known as masting, is implicated in many ecological processes, but how it arises remains poorly understood. Flowering and pollination dynamics are hypothesized to provide the mechanistic link for the observed relationship between weather and population‐level seed production. We report the first experimental test of the phenological synchrony hypotheses as a driver of pollen limitation in mast seeding oaks (Quercus ilex). Higher flowering synchrony yielded greater pollination...

Data from: Sexual and ecological selection on a sexual conflict gene

Agata Plesnar-Bielak, Anna Skwierzyńska & Jacek Radwan
Sexual selection and conflict can act on genes with important metabolic functions, potentially shaping standing genetic variance in such genes, and thus evolutionary potential of populations. Here, using experimental evolution, we show how reproductive competition intensity and thermal environment affect selection on phosphogluconate dehydrogenase (6Pgdh) – a metabolic gene involved in sexual selection and conflict in the bulb mite. The S allele of 6Pgdh increases male success in reproductive competition, but is detrimental to S-bearing...

Fia Bengtsson, Håkan Rydin, Jennifer Baltzer, Luca Bragazza, Zhao-Jun Bu, Simon Caporn, Ellen Dorrepaal, Kjell Ivar Flatberg, Olga Galanina, Mariusz Gałka, Anna Ganeva, Irina Goia, Nadezhda Goncharova, Michal Hajek, Akira Haraguchi, Lorna Harris, Elyn Humphreys, Martin Jiroušek, Katarzyna Kajukało, Edgar Karofeld, Natalia Koronatova, Natalia Kosykh, Anna Laine, Mariusz Lamentowicz, Elena Lapshina … & Richard J. Payne
The relative importance of global versus local environmental factors for growth and thus carbon uptake of the bryophyte genus Sphagnum – the main peat-former and ecosystem engineer in northern peatlands – remains unclear. 2) We measured length growth and net primary production (NPP) of two abundant Sphagnum species across 99 Holarctic peatlands. We tested the importance of previously proposed abiotic and biotic drivers for peatland carbon uptake (climate, N deposition, water table depth, and vascular...

Data from: Seed size predicts global effects of small mammal seed predation on plant recruitment

Yvette Ortega, Łukasz Dylewski, Michał Bogdziewicz & Dean Pearson
We conducted a global literature review and meta-analysis to evaluate whether seed size could predict post-dispersal seed predator effects on seed removal and plant recruitment, respectively. Datasets were built using data extracted from published studies focusing on seed predation by small mammals (see Methods for criteria and data extraction protocol). We found that seed size predicted small mammal seed removal rates and their impacts on plant recruitment consistent with optimal foraging theory, with intermediate seed...

Data from: Last Glacial Maximum environmental conditions at Andøya, northern Norway; evidence for a northern ice-edge ecological “hotspot”

Inger Alsos, Per Sjögren, Antony Brown, Ludovic Gielly, Marie Merkel, Aage Paus, Youri Lammers, Mary Edwards, Torbjørn Alm, Melanie Leng, Tomasz Goslar, Catherine Langdon, Jostein Bakke & Willem Van Der Bilt
Andøya on the NW coast of Norway is a key site for understanding the Last Glacial Maximum (LGM) in northern Europe. Controversy has arisen concerning the local conditions, especially about the timing and extent of local glacial cover, maximum July temperatures and whether pine and/or spruce could have grown there. We reviewed all existing data and add newly analysed ancient sedimentary DNA, pollen, macrofossils, geochemistry and stable isotopes from three lake sediment cores from Øvre...

Metabolic and behavioral adaptations of greater white-toothed shrews to urban conditions

Flávio Oliveira, Maria Mathias, Leszek Rychlik, Joaquim Tapisso & Sophie Von Merten
The global trend of urbanization is creating novel challenges to many animal species. Studies investigating behavioral differences between rural and urban populations often report a general increase in risk-taking behaviors in urban populations. According to the most common energy management model (the performance model), behaviors that increase access to resources, such as aggression and boldness, and behaviors that consume net energy, like locomotion and stress responses, are both positively correlated to resting metabolic rate (RMR)....

Mating preferences can drive expansion or contraction of major histocompatibility complex gene family

Piotr Bentkowski & Jacek Radwan
Major histocompatibility complex (MHC)-based mating rules can evolve as a way to avoid inbreeding or to increase offspring immune competence. While the role of mating preference in shaping the MHC diversity in vertebrates has been acknowledged, its impact on individual MHC diversity has not been considered. Here, we use computer simulations to investigate how simple mating rules favouring MHC-dissimilar partners affect the evolution of the number of MHC variants in individual genomes, accompanying selection for...

S. Cavers, W. Wachowiak & A. Perry
The dataset contains genotypes for samples used to validate a 50K single nucleotide polymorphism (SNP, DNA mutation) Axiom array for Scots pine (Pinus sylvestris) and closely related members of the Pinus mugo complex.

Scots pine single nucleotide polymorphisms (SNP) for Axiom array

S. Cavers, W. Wachowiak & A. Perry
This dataset contains ~50,000 single nucleotide polymorphisms (SNPs, DNA mutations) for Scots pine (Pinus sylvestris) and closely related members of the Pinus mugo complex, which were selected for inclusion on a 50K SNP Axiom array

Data from: Climate synchronises shrub growth across a high-arctic archipelago: contrasting implications of summer and winter warming

Mathilde Le Moullec, Lisa Sandal, Vidar Grøtan, Agata Buchwal & Brage Hansen
Climate change is most pronounced at high latitudes, where plant and animal populations are often strongly influenced by environmental fluctuations related to climate and weather. Environmental conditions can co-fluctuate over large distances and thereby synchronise primary production in space. However, large-scale studies of such spatiotemporal patterns remain rare in the Arctic, where short time-series and poor spatial replication have characterised the data available on both biotic and abiotic parameters. Here, we use dendrochronological tools to...

Data from: Sexually-selected male weapon is associated with lower inbreeding load but higher gender load in the bulb mite

Aleksandra Łukasiewicz, Jacek Radwan & Małgorzata Niśkiewicz
Elaborate sexually selected ornaments and armaments are costly but increase the reproductive success of their bearers (usually males). It has been postulated that high-quality males can invest disproportionately more in such traits, making those traits honest signals of genetic quality. However, genes associated with such traits may have sexually antagonistic effects on fitness. Here, using a bulb mite Rhizoglyphus robini, a species in which a distinct dimorphism exists between males in the expression of a...

Genotype data and analysis code for HDY-20-A0076RR

Karl Phillips & Magdalena Herdegen-Radwan
Selection pressure from parasites is thought to be a major force shaping the extreme polymorphism of the major histocompatibility complex (MHC) genes, but the modes and consequences of selection remain unclear. Here, we analyse MHC class II and microsatellite diversity in 16 guppy (Poecilia reticulata) populations from two islands (Trinidad and Tobago) that have been separated for at least 10 ky. Within-population MHC diversity was high, but allele sharing was limited within islands and even...

A fingerprint of climate change across pine forests of Sweden

Jacek Oleksyn, Tomasz Wyka, Roma Żytkowiak, Marcin Zadworny, Joanna Mucha, Monika Dering, Krzysztof Ufnalski, Bengt Nihlgard & Peter Reich
Needle traits of coniferous forests reflect environmental conditions and influence tree physiology and growth. Given the sensitivity of needle traits and tree growth to climate, temperature warming of ≈1°C in the past century may have influenced structure and function of high latitude forests across the globe. Here we show that throughout a ≈1,000 km transect in cold, high latitude Scots pine (Pinus sylvestris L.) forests in Sweden, which has warmed by ≈1°C in a century,...

Forbes, Pascale Ropars, Esther Lévesque, Bo Elberling, Sandra Angers-Blondin, Joseph S. Boyle, Stéphane Boudreau, Noémie Boulanger-Lapointe, Cassandra Gamm, Martin Hallinger, Grzegorz Rachlewicz, Amanda Young, Pentti Zetterberg & Jeffrey M. Welker
Arctic sea ice extent (SIE) is declining at an accelerating rate with a wide range of ecological consequences. However, determining sea ice effects on tundra vegetation remains a challenge. In this study, we examined the universality or lack thereof in tundra shrub growth responses to changes in SIE and summer climate across the Pan-Arctic, taking advantage of 23 tundra shrub-ring chronologies from 19 widely distributed sites (56⁰-83⁰N).
