Data from: Variation in the level of aggression, chemical and genetic distance among three supercolonies of the Argentine ant in Europe

Olivier Blight, Laurence Berville, Valerie Vogel, Abraham Hefetz, Marielle Renucci, Jerome Orgeas, Erick Provost & Laurent Keller
In their invasive ranges, Argentine ant populations often form one geographically vast supercolony, genetically and chemically uniform within which there is no intraspecific aggression. Here we present regional patterns of intraspecific aggression, cuticular hydrocarbons and population genetics of 18 nesting-sites across Corsica and the French mainland. Aggression tests confirm the presence of a third European supercolony, the Corsican supercolony, which exhibits moderate to high levels of aggression, depending on nesting-sites, with the Main supercolony, and...

Data from: Sustained high levels of neuregulin-1 in the longest-lived rodents; a key determinant of rodent longevity

Yael H. Edrey, Diana Casper, Dorothee Huchon, James Mele, Jonathan A. Gelfond, Deborah M. Kristan, Eviatar Nevo & Rochelle Buffenstein
Naked mole-rats (Heterocephalus glaber), the longest-lived rodents, live 7-10 times longer than similarly–sized mice and exhibit normal activities for ∼75% of their lives. Little is known about the mechanisms that allow them to delay the aging process and live so long. Neuregulin-1 (NRG-1) signaling is critical for normal brain function during both development and adulthood. We hypothesized that long-lived species will maintain higher levels of NRG-1 and that this contributes to their sustained brain function...

Data from: Are pollinators the agents of selection on flower colour and size in irises?

Daniel Souto-Vilarósa, Ana Vuleta, Sanja Manitašević Jovanović, Sanja Budečević, Hui Wang, Yuval Sapir & Eric Imbert
Plant-pollinator interactions are believed to play a major role in the evolution of floral traits. Flower colour and flower size are important for attracting pollinators, directly influencing reproduction, and thus expected to be under pollinator-mediated selection. Pollinator-mediated selection is also proposed to play a role in maintaining flower colour polymorphism within populations. However, pigment concentrations, and thus flower colour, are also under selective pressures independent of pollinators. We quantified phenotypic pollinator-mediated selection on flower colour...

Data from: Hydrodynamic regime determines the feeding success of larval fish through the modulation of strike kinematics

Victor China, Liraz Levy, Alex Liberzon, Tal Elmaliach & Roi Holzman
Larval fishes experience extreme mortality rates, with 99% of a cohort perishing within days after starting to actively feed. While recent evidence suggests that hydrodynamic factors contribute to constraining larval feeding during early ontogeny, feeding is a complex process that involves numerous interacting behavioural and biomechanical components. How these components change throughout ontogeny and how they contribute to feeding remain unclear. Using 339 observations of larval feeding attempts, we quantified the effects of morphological and...

Data from: Social tipping points in animal societies in response to heat stress

Grant Navid Doering, Inon Scharf, Holly V. Moeller & Jonathan N. Pruitt
Living systems sometimes experience abrupt tipping points in response to stress. Here we investigate the factors contributing to the appearance of such abrupt state transitions in animal societies. We first construct a mathematical account of how the personality compositions of societies could alter their propensity to shift from calm to violent states in response to thermal stress. To evaluate our model, we subjected experimental societies of the spider Anelosimus studiosus to heat stress. We demonstrate...

Data from: Testosterone in ancient hair from an extinct species

Lee Koren, Devorah Matas, Patrícia Pečnerová, Love Dalén, Alexei Tikhonov, M. Thomas P. Gilbert, Katherine E. Wynne-Edwards & Eli Geffen
Testosterone is a key regulator in vertebrate development, physiology, and behaviour. Whereas technology allows extraction of a wealth of genetic information from extant as well as extinct species, complimentary information on steroid hormone levels may add a social, sexual, and environmental context. Hair shafts have been previously used to sequence DNA from >50,000 14C years old Siberian woolly mammoths (Mammuthus primigenius). Hair-testing has also been used to measure endogenous steroids in multiple extant species. Here...

Data from: Traits of lizards of the world: variation around a successful evolutionary design

Shai Meiri
Motivation – over the last 12 years I have been collecting trait and geographic data on lizards. These data could be useful for scientists studying this remarkable reptilian radiation. Furthermore, as published data for some of the less well known species are scarce, I hope this study can initiate a community effort to fill in data gaps. I present geographical, morphological, ecological, physiological and life history data for the 6657 known species of lizards. I...

Data from: The large-scale drivers of population declines in a long-distance migratory shorebird

Nicholas J. Murray, Peter P. Marra, Richard A. Fuller, Robert S. Clemens, Kiran Dhanjal-Adams, Ken B. Gosbell, Chris J. Hassell, Takuya Iwamura, David Melville, Clive D. T. Minton, Adrian C. Riegen, Danny I. Rogers, Eric J. Woehler & Colin E. Studds
Migratory species can travel tens of thousands of kilometers each year, spending different parts of their annual cycle in geographically distinct locations. Understanding the drivers of population change is vital for conserving migratory species, yet the challenge of collecting data over entire geographic ranges has hindered attempts to identify the processes leading to observed population changes. Here, we use remotely sensed environmental data and count data to investigate the factors driving variability in abundance in...

Data from: Meiotic drive shapes rates of karyotype evolution in mammals

Heath Blackmon, Joshua Justison, Itay Mayrose & Emma E. Goldberg
Chromosome number is perhaps the most basic characteristic of a genome, yet generalizations that can explain the evolution of this trait across large clades have remained elusive. Using karyotype data from over 1,000 mammals, we developed and applied a phylogenetic model of chromosome evolution that links chromosome number changes with karyotype morphology. Using our model, we infer that rates of chromosome number evolution are significantly lower in species with karyotypes that consist of either all...

Data from: Genome-wide differentiation in closely related populations: the roles of selection and geographic isolation

Rebecca J. Safran, Elizabeth S. C. Scordato, Matthew R. Wilkins, Joanna K. Hubbard, Brittany R. Jenkins, Tomas Albrecht, Samuel M. Flaxman, Hakan Karaardic, Yoni Vortman, Arnon Lotem, Patrik Nosil, Péter Pap, Sheng-Feng Shen, Shih-Fan Chan, Thomas L. Parchman, Nolan C. Kane, S.-F. Chan & T.L. Parchman
Population divergence in geographic isolation is due to a combination of factors. Natural and sexual selection may be important in shaping patterns of population differentiation, a pattern referred to as ‘isolation by adaptation’ (IBA). IBA can be complementary to the well-known pattern of ‘isolation by distance’ (IBD), in which the divergence of closely related populations (via any evolutionary process) is associated with geographic isolation. The barn swallow Hirundo rustica complex comprises six closely related subspecies,...

Data from: Data gaps and opportunities for comparative and conservation biology

Dalia A. Conde, Johanna Staerk, Fernando Colchero, Rita Da Silva, Jonas Schöley, H. Maria Baden, Lionel Jouvet, John E. Fa, Hassan Syed, Eelke Jongejans, Shai Meiri, Jean-Michel Gaillard, Scott Chamberlain, Jonathan Wilcken, Owen R. Jones, Johan P. Dahlgren, Ulrich K. Steiner, Lucie M. Bland, Ivan Gomez-Mestre, Jean-Dominique Lebreton, Jaime González Vargas, Nate Flesness, Vladimir Canudas-Romo, Roberto Salguero-Gómez, Onnie Byers … & James W. Vaupel
Biodiversity loss is a major challenge. Over the past century, the average rate of vertebrate extinction has been about 100-fold higher than the estimated background rate and population declines continue to increase globally. Birth and death rates determine the pace of population increase or decline, thus driving the expansion or extinction of a species. Design of species conservation policies hence depends on demographic data (e.g., for extinction risk assessments or estimation of harvesting quotas). However,...

Data from: Stress-induced mutagenesis and complex adaptation

Yoav Ram & Lilach Hadany
Because mutations are mostly deleterious, mutation rates should be reduced by natural selection. However, mutations also provide the raw material for adaptation. Therefore, evolutionary theory suggests that the mutation rate must balance between adaptability—the ability to adapt—and adaptedness—the ability to remain adapted. We model an asexual population crossing a fitness valley and analyse the rate of complex adaptation with and without stress-induced mutagenesis (SIM)—the increase of mutation rates in response to stress or maladaptation. We...

Data from: The majority of transcripts in the squid nervous system are extensively recoded by A-to-I RNA editing

Shahar Alon, Sandra C. Garrett, Erez Y. Levanon, Sara Olson, Brenton R. Graveley, Joshua J. C. Rosenthal & Eli Eisenberg
RNA editing by adenosine deamination alters genetic information from the genomic blueprint. When it recodes mRNAs, it gives organisms the option to express diverse, functionally distinct, protein isoforms. All eumetazoans, from cnidarians to humans, express RNA editing enzymes. However, transcriptome-wide screens have only uncovered about 25 transcripts harboring conserved recoding RNA editing sites in mammals and several hundred recoding sites in Drosophila. These studies on few established models have led to the general assumption that...

Data from: Photoacclimation and induction of light-enhanced calcification in the mesophotic coral Euphyllia paradivisa

Gal Eyal, Itay Cohen, Lee Eyal-Shaham, Or Ben-Zvi, Yaron Tikochinski & Yossi Loya
Corals and their photosymbionts experience inherent changes in light along depth gradients, leading them to have evolved several well-investigated photoacclimation strategies. As coral calcification is influenced by light (a process described as LEC-“light enhanced calcification”), studies have sought to determine the link between photosynthesis and calcification, but many puzzling aspects still persist. Here we examine the physiology of Euphyllia paradivisa, a coral species found at a wide range of depths but that is strictly mesophotic...

Not a melting pot: plant species aggregate in their non-native range

Gisela C. Stotz, James F. Cahill, Jonathan A. Bennett, Cameron N. Carlyle, Edward W. Bork, Diana Askarizadeh, Sandor Bartha, Carl Beierkuhnlein, Bazartseren Boldgiv, Leslie Brown, Marcelo Cabido, Giandiego Campetella, Stefano Chelli, Ofer Cohen, Sandra Díaz, Lucas Enrico, David Ensing, Batdelger Erdenetsetseg, Alessandra Fidelis, Heath W. Garris, Hugh A.L. Henry, Anke Jentsch, Mohammad Hassan Jouri, Kadri Koorem, Peter Manning … & Lauchlan H. Fraser
Aim: Plant species continue to be moved outside of their native range by human activities. Here, we aim at determining whether, once introduced, plants assimilate into native communities, or whether they aggregate, thus forming mosaics of native- and alien-rich communities. Alien species may aggregate in their non-native range due to shared habitat preferences, such as their tendency to establish in high-biomass, species-poor areas. Location: 22 herbaceous grasslands in 14 countries, mainly in the temperate zone....

Data from: Plants’ ability to sense and respond to airborne sound is likely to be adaptive: reply to comment by Pyke et al.

Aya Goldshtein, Marine Veits, Itzhak Khait, Kfir Saban, Yuval Sapir, Yossi Yovel & Lilach Hadany
(Veits et al. 2019) demonstrated, for the first time, a rapid response of a plant to the airborne sounds of pollinators. Pyke et al. argue that this response is unlikely to be adaptive. Here we clarify some misunderstandings, and demonstrate the potential adaptive value using theoretical modelling and field observations.

Data from: Increased sugar concentration in response to a wide range of pollinator sounds can be adaptive for the plant: Answer to Raguso et al.

Marine Veits, Itzhak Khait, Arjan Boonman, Gayl Sharabi, Yuval Sapir, Yossi Yovel & Lilach Hadany
In Veits et al. we showed that flowers respond to a range of pollinator sounds by increased nectar sugar concentration. Here we clarify that (i) our argument is relevant to most pollinators, and not limited to bees (ii) specifically, bees do access O. Drumondii nectar in this area.

Data from: ALG11 – a new variable DNA marker for sponge phylogeny: comparison of phylogenetic performances with the 18S rDNA and the COI gene

Frida Belinky, Amir Szitenberg, Itay Goldfarb, Tamar Feldstein, Wörheide Gert, Micha Ilan & Dorothée Huchon
Phylogenetic relationships within sponge classes are highly debated. The low phylogenetic signal observed with some current molecular data can be attributed to the use of few markers, usually slowly-evolving, such as the nuclear rDNA genes and the mitochondrial COI gene. In this study, we conducted a bioinformatics search for a new molecular marker. We sought a marker that (1) is likely to have no paralogs; (2) evolves under a fast evolutionary rate; (3) is part...

Data from: Combined analysis of variation in core, accessory and regulatory genome regions provides a super-resolution view into the evolution of bacterial populations

Alan McNally, Yaara Oren, Darren Kelly, Ben Pascoe, Steven Dunn, Tristan Seecharan, Minna Vehkala, Niko Välimäki, Michael B. Prentice, Amgad Ashour, Oren Avram, Tal Pupko, Ulrich Dobrindt, Ivan Literak, Sebastian Guenther, Katharina Schauffler, Lothar H. Wieler, Zong Zhiyong, Samuel K. Sheppard, James O. McInerney, Jukka Corander & Tristan Sreecharan
The use of whole-genome phylogenetic analysis has revolutionized our understanding of the evolution and spread of many important bacterial pathogens due to the high resolution view it provides. However, the majority of such analyses do not consider the potential role of accessory genes when inferring evolutionary trajectories. Moreover, the recently discovered importance of the switching of gene regulatory elements suggests that an exhaustive analysis, combining information from core and accessory genes with regulatory elements could...

Data from: Coral snakes predict the evolution of mimicry across New World snakes

Alison R. Davis Rabosky, Christian L. Cox, Daniel L. Rabosky, Pascal O. Title, Iris A. Holmes, Anat Feldman & Jimmy A. McGuire
Batesian mimicry, in which harmless species (mimics) deter predators by deceitfully imitating the warning signals of noxious species (models), generates striking cases of phenotypic convergence that are classic examples of evolution by natural selection. However, mimicry of venomous coral snakes has remained controversial because of unresolved conflict between the predictions of mimicry theory and empirical patterns in the distribution and abundance of snakes. Here we integrate distributional, phenotypic and phylogenetic data across all New World...

Lifelong exposure to artificial light at night impacts stridulation and locomotion activity patterns in the cricket Gryllus bimaculatus

Keren Levy, Yoav Wegrzyn, Ronny Efronny, Anat Barnea & Amir Ayali
This dataset contains data from a laboratory experiments described in the paper: “Levy, K., Wegrzyn, Y., Efronny, R., Barnea, A., & Ayali, A. 2021 Lifelong exposure to artificial light at night impacts stridulation and locomotion activity patterns in the cricket Gryllus bimaculatus. Proc. R. Soc. B 20211626. https://doi.org/10.1098/rspb.2021.162”. Artificial light at night (ALAN) is increasing worldwide,with most of the world population living under light-polluted skies. Growing awareness of the harmful effects of ALAN calls for...

Data from: Elevation is a stronger predictor of morphological trait divergence than competition in a radiation of tropical lizards

Alex Slavenko, Allen Allison & Shai Meiri
1. Adaptations for efficient performance are expected to shape animal morphology based on selection for microhabitat use and ecological forces. The presence of competitor species is predicted to cause niches to contract and enhance trait divergence. Therefore, increased species richness is expected to lead to greater trait divergence, and to result in reduced overlap and similarity between morphologies of sympatric species. 2. We examined patterns of morphospace occupancy and partitioning in the skink fauna of...

Data from: A review of seascape complexity indices and their performance in coral and rocky reefs

Mai Lazarus & Jonathan Belmaker
Seascape complexity is an important driver of ecological processes in marine systems. Today, high resolution, multiscale bathymetric data is being collected due to rapid advances in marine technologies and image processing, drastically improving the detailed mapping of the physical structure of the seascape. However, these data are rarely synthesized to create comprehensive complexity estimates, and complexity is still mostly measured using a small set of simple indices. The aims of this study are to: (1)...

Experimental test of the combined effects of water availability and flowering time on pollinator visitation and seed set

M. Kate Gallagher & Diane Campbell
Climate change is likely to alter both flowering phenology and water availability for plants. Either of these changes alone can affect pollinator visitation and plant reproductive success. The relative impacts of phenology and water, and whether they interact in their impacts on plant reproductive success remain, however, largely unexplored. We manipulated flowering phenology and soil moisture in a factorial experiment with the subalpine perennial Mertensia ciliata (Boraginaceae). We examined responses of floral traits, floral abundance,...

Kinematic and morphological data from: Trophic guilds of suction-feeding fish are distinguished by their characteristic hydrodynamics of swimming and feeding

Karin Olsson, Roi Gurka & Roi Holzman
Suction-feeding in fish is a ubiquitous form of prey capture whose outcome depends both on the movements of the predator and the prey, and on the dynamics of the surrounding fluid, which exerts forces on the two organisms. The inherent complexity of suction-feeding has challenged previous efforts to understand how the feeding strikes are modified when species evolve to feed on different prey types. Here, we utilize the concept of dynamic similarity, commonly applied to...
