Data from: Using metagenomics to show the efficacy of forest restoration in the New Jersey Pine Barrens

William D. Eaton, Shadi Shokralla, Kathleen M. McGee & Mehrdad Hajibabaei
The Franklin Parker Preserve within the New Jersey Pine Barrens contains 5,000 acres of wetlands habitat, including old-growth Atlantic White Cedar (or AWC; Chamaecyparis thyoides) swamps, cranberry bogs, and former cranberry bogs undergoing restoration into AWC forests. This study showed that the C-use efficiency was greater in the old-growth AWC soils than in soils from 8-year old mid-stage restored AWC stands, which were greater than found in soil from 4-year old AWC stands—the latter two...

Data from: Physiological effects of temperature do not explain prevalence of females in populations of gynodioecious Lobelia siphilitica growing in warmer climates

Maia F. Bailey, Andrea L. Case & Christina M. Caruso
PREMISE OF THE STUDY: Gynodioecy is a sexual polymorphism whereby female and hermaphroditic plants co-occur within populations. In many gynodioecious species, stressful abiotic environments are associated with higher frequencies of females. This association suggests that abiotic stress affects the relative fitness of females and hermaphrodites and, thus, the maintenance of gynodioecy. METHODS:To test whether abiotic stress affects the fitness of females and hermaphrodites, we grew open-pollinated Lobelia siphilitica families in temperature regimes characteristic of the...

Data from: Reducing cryptic relatedness in genomic datasets via a central node exclusion algorithm

Pablo A.S. Fonseca, Thiago P. Leal, Fernanda Caroline Santos, Mateus Henrique Gouveia, Samir Id-Lahoucine, Izinara C. Rosse, Ricardo V. Ventura, Frank Angelo T. Bruneli, Marco Antônio Machado, Maria Gabriela C.D. Peixoto, Eduardo Tarazona-Santos, Maria Raquel S. Carvalho & Pablo A. S. Fonseca
Cryptic relatedness is a confounding factor in genetic diversity and genetic association studies. Development of strategies to reduce cryptic relatedness in a sample is a crucial step for downstream genetic analyzes. The present study uses a node selection algorithm, based on network degrees of centrality, to evaluate its applicability and impact on evaluation of genetic diversity and population stratification. 1,036 Guzerá (Bos indicus) females were genotyped using Illumina Bovine SNP50 v2 BeadChip. Four strategies were...

Data from: Why hate the good guy? Antisocial punishment of high cooperators is greater when people compete to be chosen

Aleta Pleasant & Pat Barclay
When choosing social partners, people prefer good cooperators (all else equal). Given this preference, anyone wishing to be chosen can either increase their own cooperation to become more desirable, or suppress others’ cooperation to make them less desirable. Previous research shows that very cooperative people sometimes get punished (“antisocial punishment”) or criticized (“do-gooder derogation”) in many cultures. Here we use a public goods game with punishment to test whether antisocial punishment is used as a...

Data from: Climatic niche evolution is faster in sympatric than allopatric lineages of the butterfly genus Pyrgus

Camille Pitteloud, Nils Arrigo, Tomasz Suchan, Alicia Mastretta-Yanes, Roger Vila, Vlad Dinca, Juan Hernández-Roldán, Ernst Brockmann, Yannick Chittaro, Irena Kleckova, Luca Fumagalli, Sven Buerki, Loïc Pellissier & Nadir Alvarez
Understanding how speciation relates to ecological divergence has long fascinated biologists. It is assumed that ecological divergence is essential to sympatric speciation, as a mechanism to avoid competition and eventually lead to reproductive isolation, while divergence in allopatry is not necessarily associated with niche differentiation. The impact of the spatial context of divergence on the evolutionary rates of abiotic dimensions of the ecological niche has rarely been explored for an entire clade. Here, we compare...

Data from: Responses of neurogenesis and neuroplasticity related genes to elevated CO2 levels in the brain of three teleost species

Floriana Lai, Cathrine E. Fagernes, Nicholas J. Bernier, Gabrielle M. Miller, Philip L. Munday, Fredrik Jutfelt & Göran E. Nilsson
The continuous increase of anthropogenic CO2 in the atmosphere resulting in ocean acidification has been reported to affect brain function in some fishes. During adulthood, cell proliferation is fundamental for fish brain growth and for it to adapt in response to external stimuli, such as environmental changes. Here we report the first expression study of genes regulating neurogenesis and neuroplasticity in brains of three-spined stickleback (Gasterosteus aculeatus), cinnamon anemonefish (Amphiprion melanopus) and spiny damselfish (Acanthochromis...

Data from: CRISPR-induced null alleles show that Frost protects Drosophila melanogaster reproduction after cold exposure

Claire E. Newman, Jantina Toxopeus, Hiroko Udaka, Soohyun Ahn, David M. Martynowicz, Steffen P. Graether, Brent J. Sinclair & Anthony Percival-Smith
The ability to survive and reproduce after cold exposure is important in all kingdoms of life. However, even in a sophisticated genetic model system like Drosophila melanogaster, few genes have been identified as functioning in cold tolerance. The accumulation of the Frost (Fst) gene transcript increases after cold exposure, making it a good candidate for a gene that has a role in cold tolerance. However, despite extensive RNAi knockdown analysis, no role in cold tolerance...

Data from: Precipitation drives global variation in natural selection

Adam Siepielski, Michael B. Morrissey, Mathieu Buoro, Stephanie M. Carlson, Christina M. Caruso, Sonya M. Clegg, Tim Coulson, Joseph DiBattista, Kiyoko M. Gotanda, Clinton D. Francis, Joe Hereford, Joel G. Kingsolver, Kate E. Augustine, Loeske E. B. Kruuk, Ryan A. Martin, Ben C. Sheldon, Nina Sletvold, Erik I. Svensson, Michael J. Wade & Andrew D. C. MacColl
Climate change has the potential to affect the ecology and evolution of every species on Earth. Although the ecological consequences of climate change are increasingly well documented, the effects of climate on the key evolutionary process driving adaptation—natural selection—are largely unknown. We report that aspects of precipitation and potential evapotranspiration, along with the North Atlantic Oscillation, predicted variation in selection across plant and animal populations throughout many terrestrial biomes, whereas temperature explained little variation. By...

Data from: Huygens' clocks revisited

Allan R. Willms, Petko M. Kitanov & William F. Langford
In 1665, Huygens observed that two identical pendulum clocks, weakly coupled through a heavy beam, soon synchronized with the same period and amplitude but with the two pendula swinging in opposite directions. This behaviour is now called anti-phase synchronization. This paper presents an analysis of the behaviour of a large class of coupled identical oscillators, including Huygens' clocks, using methods of equivariant bifurcation theory. The equivariant normal form for such systems is developed and the...

Data from: Compensatory selection for roads over natural linear features by wolves in northern Ontario: implications for caribou conservation

Erica J. Newton, Brent R. Patterson, Morgan L. Anderson, Arthur R. Rodgers, Lucas M. Vander Vennen & John M. Fryxell
Woodland caribou (Rangifer tarandus caribou) in Ontario are a threatened species that have experienced a substantial retraction of their historic range. Part of their decline has been attributed to increasing densities of anthropogenic linear features such as trails, roads, railways, and hydro lines. These features have been shown to increase the search efficiency and kill rate of wolves. However, it is unclear whether selection for anthropogenic linear features is additive or compensatory to selection for...

Data from: Multilevel and sex-specific selection on competitive traits in North American red squirrels.

David N. Fisher, Stan Boutin, Ben Dantzer, Murray M. Humphries, Jeffrey E. Lane & Andrew G. McAdam
Individuals often interact more closely with some members of the population (e.g. offspring, siblings or group members) than they do with other individuals. This structuring of interactions can lead to multilevel natural selection, where traits expressed at the group-level influence fitness alongside individual-level traits. Such multilevel selection can alter evolutionary trajectories, yet is rarely quantified in the wild, especially for species that do not interact in clearly demarcated groups. We quantified multilevel natural selection on...

Data from: Selective plant foraging and the top-down suppression of native diversity in a restored prairie

Stefan Schneider, Royce Steeves, Steven Newmaster, Andrew S. MacDougall & Steve Newmaster
Clarifying what species are being consumed at what times can improve our understanding of how anthropogenic change affects food web dynamics, with implications for community assembly including restoration. This includes human-based changes to plant communities via species introductions, which can interact with consumer feeding preferences to indirectly alter assembly outcomes including reduced restoration success if planted species are preferentially targeted. We used DNA barcoding of plant material in rodent scat, combined with field-based feeding trials,...

Data from: Subtle individual variation in indeterminate growth leads to major variation in survival and lifetime reproductive output in a long-lived reptile

Doug P. Armstrong, Matthew G. Keevil, Njal Rollinson & Ronald J. Brooks
1. The consequences of individual variation in life-history traits have been well studied due to their importance in evolutionary ecology. However, a trait that has received little empirical attention is the rate of indeterminate growth. In long-lived ectotherms, subtle variation in growth after maturity could have major effects over the animals’ lifetimes. 2. These effects are difficult to measure due to the challenges involved in reliably estimating individual variation in the face of environmental stochasticity,...

Data from: Flexible mate choice may contribute to ecotype assortative mating in pumpkinseed sunfish (Lepomis gibbosus)

Will M.C. Jarvis, Shevon M. Comeau, Scott F. Colborne, Beren W. Robinson & W. M. C. Jarvis
Gene flow is expected to limit adaptive divergence but the ecological and behavioural factors that govern gene flow are still poorly understood, particularly at the earliest stages of population divergence. Reduced gene flow through mate choice (sexual isolation) can evolve even under conditions of subtle population divergence if intermediate phenotypes have reduced fitness. We indirectly tested the hypothesis that mate choice has evolved between coexisting littoral and pelagic ecotypes of polyphenic pumpkinseed sunfish (Lepomis gibbosus)...

Data from: The ecology of avian influenza viruses in wild dabbling ducks (Anas spp.) in Canada

Zsuzsanna Papp, Robert G. Clark, E. Jane Parmley, Frederick A. Leighton, Cheryl Waldner & Catherine Soos
Avian influenza virus (AIV) occurrence and transmission remain important wildlife and human health issues in much of the world, including in North America. Through Canada's Inter-Agency Wild Bird Influenza Survey, close to 20,000 apparently healthy, wild dabbling ducks (of seven species) were tested for AIV between 2005 and 2011. We used these data to identify and evaluate ecological and demographic correlates of infection with low pathogenic AIVs in wild dabbling ducks (Anas spp.) across Canada....

Data from: DNA metabarcoding for high-throughput monitoring of estuarine macrobenthic communities

Jorge Lobo, Shadi Shokralla, Maria Helena Costa, Mehrdad Hajibabaei & Filipe Costa
Morphology-based profiling of benthic communities has been extensively applied to aquatic ecosystems' health assessment. However, it remains a low-throughput, and sometimes ambiguous, procedure. Despite DNA metabarcoding has been applied to marine benthos, a comprehensive approach providing species-level identifications for estuarine macrobenthos is still lacking. Here we report a combination of experimental and field studies to assess the aptitude of COI metabarcoding to provide robust species-level identifications for high-throughput monitoring of estuarine macrobenthos. To investigate the...

Data from: Signatures of selection in mammalian clock genes with coding trinucleotide repeats: implications for studying the genomics of high-pace adaptation

Melanie B. Prentice, Jeff Bowman, Jillian L. Lalor, Michelle M. McKay, Lindsay A. Thomson, Cristen M. Watt, Andrew G. McAdam, Dennis L. Murray & Paul J. Wilson
Climate change is predicted to affect the reproductive ecology of wildlife; however, we have yet to understand if and how species can adapt to the rapid pace of change. Clock genes are functional genes likely critical for adaptation to shifting seasonal conditions through shifts in timing cues. Many of these genes contain coding trinucleotide repeats, which offer the potential for higher rates of change than single nucleotide polymorphisms (SNPs) at coding sites, and, thus, may...

Data from: Host specificity in subarctic aphids

Daniel J. Gibson, Sarah J. Adamowicz, Shoshanah R. Jacobs & Alex M. Smith
The specificity of parasitic interaction depends on the adaptations of both the host and the parasite. Over time, these interactions evolve and change as a result of an “arms race” between host and parasite, and the resulting species-specific adaptations may be maintained, perpetuating these interactions across speciation events. With speciation and species sorting over time, complex systems of interactions evolve. Here, we elucidate some of these interactions using the aphids (Hemiptera: Aphididae) of Churchill as...
