Data from: Plio-Pleistocene phylogeography of the Southeast Asian Blue Panchax killifish, Aplocheilus panchax

Samantha V. Beck, Gary R. Carvalho, Axel Barlow, Lukas Rüber, Heok Hui Tan, Estu Nugroho, Daisy Wowor, Siti Azizah Mohd Nor, Fabian Herder, Zainal A. Muchlisin & Mark De Bruyn
The complex climatic and geological history of Southeast Asia has shaped this region’s high biodiversity. In particular, sea level fluctuations associated with repeated glacial cycles during the Pleistocene both facilitated, and limited, connectivity between populations. In this study, we used data from two mitochondrial and three anonymous nuclear markers to determine whether a fresh/brackish water killifish, Aplocheilus panchax, Hamilton, 1822, could be used to further understand how climatic oscillations and associated sea level fluctuations have...

Deer density drives habitat use of establishing wolves in the Western European Alps

Stefanie Roder, François Biollaz, Stéphane Mettaz, Fridolin Zimmermann, Ralph Manz, Marc Kery, Sergio Vignali, Luca Fumagalli, Raphaël Arlettaz & Veronika Braunisch
1. The return of top carnivores to their historical range triggers conflicts with the interests of different stakeholder groups. Anticipating such conflicts is key to appropriate conservation management, which calls for reliable spatial predictions of future carnivore occurrence. Previous models have assessed general habitat suitability for wolves, but the factors driving the settlement of dispersing individuals remain ill-understood. In particular, little attention has been paid to the role of prey availability in the recolonization process....

Data from: Task-dependent workload adjustment of female breeders in a cooperatively breeding fish

Hirokazu Tanaka, Joachim G. Frommen, Leif Engqvist & Masanori Kohda
Parental investment affects the future survival and reproductive success of breeders. Therefore, breeders should optimize the amount of care they invest into the current offspring. In cooperative breeding systems, the amount of breeders’ parental care is influenced by the behavior of brood-care helpers. Such workload adjustment is expected to depend on the task that needs to be fulfilled. While investment rules of breeders in respect to single tasks are well investigated in many bird and...

Data from: Evolutionary conserved neural signature of early life stress affects animal social competence

Cecilia Nyman, Stefan Fischer, Nadia Aubin-Horth & Barbara Taborsky
In vertebrates the early social environment can persistently influence behaviour and social competence later in life. However, the molecular mechanisms underlying variation in animal social competence are largely unknown. In rats, high-quality maternal care causes an upregulation of hippocampal glucocorticoid receptors (gr) and reduces offspring stress responsiveness. This identifies gr regulation as a candidate mechanism for maintaining variation in animal social competence. We tested this hypothesis in a highly-social cichlid fish, Neolamprologus pulcher, reared with...

Data from: Plasticity via feedback reduces the cost of developmental instability

Remi Matthey-Doret
Costs of plasticity are thought to have important physiological and evolutionary consequences. A commonly predicted cost to plasticity is that plastic genotypes are likely to suffer from developmental instability. Adaptive plasticity requires that the developing organism can in some way sense what environment it is in or how well it is performing in that environment. These two information pathways—an “environmental signal” or a “performance signal” that indicates how well a developing phenotype matches the optimum...

Light availability and light demand of plants shape the arbuscular fungal communities in their roots

Lena Neuenkamp, Martin Zobel, Kadri Koorem, Teele Jairus, John Davison, Maarj Öpik, Martti Vasar & Mari Moora
Plants involved in the arbuscular mycorrhizal (AM) symbiosis trade photosynthetically derived carbon for fungal-provided soil nutrients. However, little is known about how plant light demand and ambient light conditions influence root-associating AM fungal communities. We conducted a manipulative field experiment to test whether plants’ shade tolerance influences their root AM fungal communities in open and shaded grassland sites. We found similar light-dependent shifts shifts in AM fungal community structure for experimental bait plant roots and...

The genome of Draba nivalis shows signatures of adaptation to the extreme environmental stresses of the Arctic

Michael Nowak, Siri Birkeland, Terezie Mandáková, Rimjhim Roy Choudhury, Xinyi Guo, Lovisa Gustafsson, Abel Gizaw, Audun Schrøder-Nielsen, Marco Fracassetti, Anne Brysting, Loren Rieseberg, Tanja Slotte, Christian Parisod, Martin Lysak & Christian Brochmann
The Arctic is one of the most extreme terrestrial environments on the planet. Here we present the first complete genome assembly of a plant adapted to the high Arctic, Draba nivalis (Brassicaceae), an attractive model species for studying plant adaptation to the stresses imposed by this harsh environment. We used an iterative scaffolding strategy with data from short-reads, single-molecule long reads, proximity ligation data, and a genetic map to produce a 302 Mb assembly that...

Experimental predator intrusions in a cooperative breeder reveal threat-dependent task partitioning

Dario Josi, Annika Freudiger, Michael Taborsky & Joachim G. Frommen
In cooperatively breeding species, non-breeding individuals provide alloparental care and help in territory maintenance and defence. Antipredator behaviours of subordinates can enhance offspring survival, which may provide direct and indirect fitness benefits to all group members. Helping abilities and involved costs and benefits, risks and outside options (e.g. breeding independently) usually diverge between group members, which calls for status-specific differentiated behavioural responses. Such role differentiation within groups may generate task-specific division of labour, as exemplified...

Data from: What doesn’t kill you makes you stronger: the burdens and benefits of toxin sequestration in a milkweed aphid

Tobias Züst, Sophie Mou & Anurag A. Agrawal
1. Specialized insect herbivores commonly co-opt plant defences for protection against predators, but the costs, benefits, and mechanisms of sequestration are poorly understood. 2. We quantified sequestration of toxic cardenolides by the specialist aphid Aphis nerii when reared on four closely related milkweed (Asclepias) species with >20-fold variation in cardenolide content, and in the presence or absence of ladybug predators. 3. Increasing concentrations of apolar plant cardenolides increased sequestered amounts in aphids. High concentrations in...

Data from: Background selection and biased gene conversion affect more than 95% of the human genome and bias demographic inferences

Fanny Pouyet, Simon Aeschbacher, Alexandre Thiéry & Laurent Excoffier
Disentangling the effect on genomic diversity of natural selection from that of demography is notoriously difficult, but necessary to properly reconstruct the history of species. Here, we use high-quality human genomic data to show that purifying selection at linked sites (i.e. background selection, BGS) and GC-biased gene conversion (gBGC) together affect as much as 95% of the variants of our genome. We find that the magnitude and relative importance of BGS and gBGC are largely...

Data from: Resting-state gamma-band power alterations in schizophrenia reveal E/I-balance abnormalities across illness-stages

Tineke Grent-'T-Jong, Joachim Gross, Jozien Goense, Michael Wibral, Ruchika Gajwani, Andrew I. Gumley, Stephen M. Lawrie, Matthias Schwannauer, Frauke Schultze-Lutter, Tobias Navarro Schröder, Dagmar Koethe, F. Markus Leweke, Wolf Singer & Peter J. Uhlhaas
We examined alterations in E/I-balance in schizophrenia (ScZ) through measurements of resting-state gamma-band activity in participants meeting clinical high-risk (CHR) criteria (n = 88), 21 first episode (FEP) patients and 34 chronic ScZ-patients. Furthermore, MRS-data were obtained in CHR-participants and matched controls. Magnetoencephalographic (MEG) resting-state activity was examined at source level and MEG-data were correlated with neuropsychological scores and clinical symptoms. CHR-participants were characterized by increased 64–90 Hz power. In contrast, FEP- and ScZ-patients showed...

Data from: Wildflower strips enhance pollination in adjacent strawberry crops at the small scale

Dominik Ganser, Barbara Mayr, Matthias Albrecht & Eva Knop
Wildflower strips (WFS) are increasingly used to counteract the negative consequences of agricultural intensification. To date, it is poorly understood how WFS promote flower visitation and pollination services in nearby insect-pollinated crops. We therefore ask whether WFS enhance pollination service in adjacent strawberry crops, and how such an effect depends on the distance from WFS. Over two years we examined the effects of experimentally sown WFS compared to grassy strips on pollination services in adjacent...

Globally, plant-soil feedbacks are weak predictors of plant abundance

Kurt Reinhart, Jonathan Bauer, Sarah McCarthy-Neumann, Andrew MacDougall, José Hierro, Mariana Chiuffo, Scott Mangan, Johannes Heinze, Joana Bergmann, Jasmin Joshi, Richard Duncan, Jeff Diaz, Paul Kardol, Gemma Rutten, Markus Fischer, Wim Van Der Putten, T. Bezemer & John Klironomos
Plant-soil feedbacks (PSFs) have been shown to strongly affect plant performance under controlled conditions, and PSFs are thought to have far reaching consequences for plant population dynamics and the structuring of plant communities. However, thus far the relationship between PSF and plant species abundance in the field is not consistent. Here, we synthesize PSF experiments from tropical forests to semiarid grasslands, and test for a positive relationship between plant abundance in the field and PSFs...

Data from: The onset of ecological diversification 50 years after colonization of a crater lake by haplochromine cichlid fishes

Florian N. Moser, Jacco C. Rijssel, Salome Mwaiko, Joana I. Meier, Benjamin Ngatunga, Ole Seehausen & Jacco C. Van Rijssel
Adaptive radiation research typically relies on the study of evolution in retrospective, leaving the predictive value of the concept hard to evaluate. Several radiations, including the cichlid fish in the East African Great Lakes, have been studied extensively, yet no study has investigated the onset of the intraspecific processes of niche expansion and differentiation shortly after colonization of an adaptive zone by cichlids. Haplochromine cichlids of one of the two lineages that seeded the Lake...

Data from: Biotic predictors complement models of bat and bird responses to climate and tree diversity in European forests

Luc Barbaro, Eric Allan, Evy Ampoorter, Bastien Castagneyrol, Yohan Charbonnier, Hans De Wandeler, Christian Kerbiriou, Harriet Milligan, Aude Vialatte, Monique Carnol, Marc Deconchat, Pallieter De Smedt, Herve Jactel, Julia Koricheva, Isabelle Le Viol, Bart Muys, Michael Scherer-Lorenzen, Kris Verheyen & Fons Van Der Plas
Bats and birds are key providers of ecosystem services in forests. How climate and habitat jointly shape their communities is well studied, but whether biotic predictors from other trophic levels may improve bird and bat diversity models is less known, especially across large bioclimatic gradients. Here, we achieved multi-taxa surveys in 209 mature forests replicated in six European countries from Spain to Finland, to investigate the importance of biotic predictors (i.e., the abundance or activity...

Data from: Plant functional groups mediate drought resistance and recovery in a multi-site grassland experiment

Kathleen A. Mackie, Michaela Zeiter, Juliette M.G. Bloor, Andreas Stampfli & Juliette M. G. Bloor
1. Climate change predictions suggest that summer droughts will become more intense and recurrent in Europe. While drought-induced reductions in grassland primary productivity are well documented, the drivers behind drought resistance (the capacity to withstand change) and recovery (the capacity for recovery of function) of above- and belowground biomass remain poorly understood. 2. Across eight grasslands differing in plant community productivity (CP) we investigated the effects of summer drought on plant and soil microbial variables,...

Data from: Differential introgression of a female competitive trait in a hybrid zone between sex-role reversed species

Sara E. Lipshutz, Joana I. Meier, Matthew J. Miller, Graham Derryberry, Ole Seehausen & Elizabeth Perrault Derryberry
Mating behavior between recently diverged species in secondary contact can impede or promote reproductive isolation. Traditionally, researchers focus on the importance of female mate choice and male-male competition in maintaining or eroding species barriers. Although female-female competition is widespread, little is known about its role in the speciation process. Here, we investigate a case of interspecific female competition and its influence on patterns of phenotypic and genetic introgression between species. We examine a hybrid zone...

Species specific plant-mediated effects between herbivores converge at high damage intensity

Jinlong Wan, Jiahui Yi, Zhibin Tao, Zhikun Ren, Evans Otieno, Baoliang Tian, Jianqing Ding, Evan Siemann, Matthias Erb & Wei Huang
Plants are often exposed to multiple herbivores and densities of these attackers (or corresponding damage intensities) generally fluctuate greatly in the field. Plant-mediated interactions vary among herbivore species and with changing feeding intensity, but little is known about how herbivore identity and density interact to determine plant responses and herbivore fitness. Here, we investigated this question using Triadica sebifera (tallow) and its two major specialist insect herbivores, Bikasha collaris (flea beetle) and Heterapoderopsis bicallosicollis (weevil)....

Projected climate risk of aquatic food system benefits

Michelle Tigchelaar, William Cheung, Essam Mohammed, Michael Phillips, Hanna Payne, Elizabeth Selig, Colette Wabnitz, Muhammed Oyinlola, Thomas Frölicher, Jessica Gephart, Christopher Golden, Edward Allison, Abigail Bennett, Ling Cao, Jessica Fanzo, Benjamin Halpern, Fiorenza Micheli, Rosamond Naylor, Rashid Sumaila, Alessandro Tagliabue & Max Troell
Aquatic foods from marine and freshwater systems are critical to the nutrition, health, livelihoods, economies and culture of billions of people worldwide – but climate-related hazards may compromise their ability to provide these benefits. This analysis estimates national-level aquatic food system climate risk using a fuzzy logic modeling approach that connects climate hazards impacting marine and freshwater capture fisheries and aquaculture to their contributions to sustainable food system outcomes, and vulnerability to losing those contributions....

A predictive flight-altitude model for avoiding future conflicts between an emblematic raptor and wind energy development in the Swiss Alps

Sergio Vignali, Franziska Lörcher, Daniel Hegglin, Raphaël Arlettaz & Veronika Braunisch
Deployment of wind energy is proposed as a mechanism to reduce greenhouse gas emissions. Yet, wind energy and large birds, notably soaring raptors, both depend on suitable wind conditions. Conflicts in airspace use may thus arise between wind energy development and wildlife protection due to the risks of collisions of birds with the blades of wind turbines. Using locations of GPS-tagged bearded vultures, a rare scavenging raptor reintroduced into the Alps, we built a spatially-explicit...

Divergent trait responses to nitrogen addition in tall and short species

Yikang Cheng, Xiang Liu, Xianhui Zhou, Shurong Zhou & Eric Allan
Asymmetrical light competition has been proposed as the main driving force of species richness decline under nitrogen (N) addition. N addition is known to cause a series of correlated changes in functional traits, with functional composition shifting due to increased dominance of tall and resource acquisitive species. However, whether trait changes vary between species and, in particular, how the traits of tall and short species respond to N addition has rarely been studied. We measured...
