title: Data from: The jellification of north temperate lakes

description: Calcium (Ca) concentrations are decreasing in softwater lakes across
 eastern North America and western Europe. Using long-term contemporary and
 palaeo-environmental field data, we show that this is precipitating a
 dramatic change in Canadian lakes: the replacement of previously dominant
 pelagic herbivores (Ca-rich Daphnia species) by Holopedium glacialis, a
 jelly-clad, Ca-poor competitor. In some lakes, this transformation is
 being facilitated by increases in macro-invertebrate predation, both from
 native (Chaoborus spp.) and introduced (Bythotrephes longimanus)
 zooplanktivores, to which Holopedium, with its jelly coat, is relatively
 invulnerable. Greater representation by Holopedium within cladoceran
 zooplankton communities will reduce nutrient transfer through food webs,
 given their lower phosphorus content relative to daphniids, and greater
 absolute abundances may pose long-term problems to water users. The
 dominance of jelly-clad zooplankton will likely persist while lakewater Ca
 levels remain low.

 Ontario lakesWe tested the mechanisms
 underlying increases in the relative and absolute abundance of Holopedium
 glacialis in the planktonic cladoceran assemblage of 8 central-Ontario,
 Canada lakes that were sampled monthly for 30 years. Zooplankton were
 sampled during the ice-free season near the point of maximum depth by
 using a metered, 76 μm mesh, tow net. The net was deployed in 4 to 7
 vertical hauls and its contents were combined to produce a composite that
 corrected for the diminution of lake stratum volume with depth. A minimum
 of 250 crustacean zooplankton were enumerated in each composite,
 subsampling to ensure that no taxon comprised more than 10% of the total
 count. Phytoplankton were sampled through the euphotic zone, and water
 chemistry samples were volume-weighted composites of all depths during
 isothermal periods, and of the mixed layers during periods of vernal and
 autumnal stratification. Dissolved oxygen profiles were generated at 1-2 m
 intervals from all depths. Finally, abundances of the zooplanktivore,
 Chaoborus spp. were quantified in samples from night-time vertical hauls
 at 10 stations visited during the autumn in all lakes in 1986 and in one
 lake from 1987-1994. In the laboratory, a minimum of 300 cells, colonies,
 or filaments of phytoplankton were counted within the Bacillariophyceae,
 Chlorophyceae, Cryptophyceae, Dinophyceae, and Euglenophyceae. Dimensions
 of all counted algae were measured, and summed to express values as an
 "edible" phytoplankton biovolume.Longitudinal

title: Trophic complexity in aqueous systems: bacterial species richness and protistan predation regulate dissolved organic carbon and dissolved total nitrogen removal

description: Loading of water bodies with dissolved organic carbon (DOC) and dissolved
 total nitrogen (DTN) affects their integrity and functioning. Microbial
 interactions mitigate the negative effects of high nutrient loads in these
 ecosystems. Despite numerous studies on how biodiversity mediates
 ecosystem functions, whether and how diversity and complexity of microbial
 food webs (horizontal, vertical) and the underlying ecological mechanisms
 influence nutrient removal has barely been investigated. Using microbial
 microcosms accommodating systematic combinations of prey (bacteria) and
 predator (protists) species, we showed that increasing bacterial richness
 improved the extent and reliability of DOC and DTN removal. Bacterial
 diversity drove nutrient removal either due to species foraging physiology
 or functional redundancy, whereas protistan diversity affected nutrient
 removal through bacterial prey resource partitioning and changing nutrient
 balance in the system. Our results demonstrate that prey–predator
 diversity and trophic interactions interactively determine nutrient
 contents, thus implying the vital role of microbial trophic complexity as
 a biological buffer against DOC and DTN.

title: Data from: Anthropogenic noise, but not artificial light levels predicts song behaviour in an equatorial bird

description: Birds in cities start singing earlier in the morning than in rural areas;
 commonly this shift is attributed to light pollution. Some studies have
 suggested that traffic noise has a stronger influence on singing activity
 than artificial light does. Changes in the timing of singing behaviour in
 relation to noise and light pollution have only been investigated in the
 temperate zones. Tropical birds, however, experience little seasonal
 variation in day length and may be less dependent on light intensity as a
 modifier for reproductive behaviours such as song. To test whether noise
 or light pollution has a stronger impact on the dawn chorus of a tropical
 bird, we investigated the singing behaviour of rufous-collared sparrows
 (Zonotrichia capensis) in Bogota, Colombia at two times during the year.
 We found that birds in places with high noise levels started to sing
 earlier. Light pollution did not have a significant effect. Birds may
 begin to sing earlier in noisy areas to avoid acoustic masking by traffic
 later in the morning. Our results also suggest that some tropical birds
 may be less sensitive to variations in day length and thus less sensitive
 to light pollution.

title: Data from: Evolutionarily accelerated invasions: the rate of dispersal evolves upwards during the range advance of cane toads

description: Human activities are changing habitats and climates, and causing
 species' ranges to shift. Range expansion brings into play a set of
 powerful evolutionary forces at the expanding range edge that act to
 increase dispersal rates. One likely consequence of these forces is
 accelerating rates of range advance due to evolved increases in dispersal
 on the range edge. In northern Australia, cane toads have increased their
 rate of spread five-fold in the last 70 years. Our breeding trials with
 toads from populations spanning the species' invasion history in
 Australia suggest a genetic basis to dispersal rates, and interpopulation
 genetic variation in such rates. Toads whose parents were from the
 expanding range front dispersed faster than toads whose parents were from
 the core of the range. This difference reflects patterns found in their
 field-collected mothers and fathers, and points to heritable variance in
 the traits that have accelerated the toads' rate of invasion across
 tropical Australia over recent decades. Taken together with demonstrated
 spatial assortment by dispersal ability occurring on the expanding front,
 these results point firmly to ongoing evolution as a driving force in the
 accelerated expansion of toads across northern Australia.

title: Data from: Delay of gratification is associated with white matter connectivity in the dorsal prefrontal cortex: a diffusion tensor imaging study in chimpanzees (Pan troglodytes)

description: Individual variability in delay of gratification (DG) is associated with a
 number of important outcomes in both non-human and human primates. Using
 diffusion tensor imaging (DTI), this study describes the relationship
 between probabilistic estimates of white matter tracts projecting from the
 caudate to the prefrontal cortex (PFC) and DG abilities in a sample of 49
 captive chimpanzees (Pan troglodytes). After accounting for time between
 collection of DTI scans and DG measurement, age and sex, higher white
 matter connectivity between the caudate and right dorsal PFC was found to
 be significantly associated with the acquisition (i.e. training phase) but
 not the maintenance of DG abilities. No other associations were found to
 be significant. The integrity of white matter connectivity between regions
 of the striatum and the PFC appear to be associated with inhibitory
 control in chimpanzees, with perturbations on this circuit potentially
 leading to a variety of maladaptive outcomes. Additionally, results have
 potential translational implications for understanding the pathophysiology
 of a number of psychiatric and clinical outcomes in humans.

title: Data from: Urban warming reduces aboveground carbon storage

description: A substantial amount of global carbon is stored in mature trees. However,
 no experiments to date test how warming affects mature tree carbon
 storage. Using a unique, citywide, factorial experiment, we investigated
 how warming and insect herbivory affected physiological function and
 carbon sequestration (carbon stored per year) of mature trees. Urban
 warming increased herbivorous arthropod abundance on trees, but these
 herbivores had negligible effects on tree carbon sequestration. Instead,
 urban warming was associated with an estimated 12% loss of carbon
 sequestration, in part because photosynthesis was reduced at hotter sites.
 Ecosystem service assessments that do not consider urban conditions may
 overestimate urban tree carbon storage. Because urban and global warming
 are becoming more intense, our results suggest that urban trees will
 sequester even less carbon in the future.

title: Data from: The adaptive potential of subtropical rainbowfish in the face of climate change: heritability and heritable plasticity for the expression of candidate genes

description: Whilst adaptation and phenotypic plasticity might buffer species against
 habitat degradation associated with global climate change, few studies
 making such claims also possess the necessary and sufficient data to
 support them. Doing so requires demonstration of heritable variation in
 traits affecting fitness under new environmental conditions. We address
 this issue using an emerging aquatic system to study adaptation to climate
 change, the crimson-spotted rainbowfish (Melanotaenia duboulayi), a
 freshwater species from a region of eastern Australia projected to be
 affected by marked temperature increases. Captive born M. duboulayi of
 known pedigree were used to assess the long-term effects of contemporary
 and 2070-projected summer temperatures on the expression of genes
 previously identified in a climate change transcriptomics (RNA-Seq)
 experiment. Nearly all genes responded to increasing temperature.
 Significant additive genetic variance explained a moderate proportion of
 transcriptional variation for all genes. Most genes also showed
 broad-sense genetic variation in transcriptional plasticity. Additionally,
 molecular pathways of candidate genes co-occur with genes inferred to be
 under climate-mediated selection in wild M. duboulayi populations.
 Together, these results indicate the presence of existing variation in
 important physiological traits, and the potential for adaptive responses
 to a changing thermal environment.
description: mRNA transcription of
 candidate genes for thermal adaptation in the crimson-spotted
 rainbowfish.Total mRNA was extracted
 from laboratory bred and reared individuals (F1); parents were wild-caught
 and originated from the Brisbane River. At 6 months of age, individuals
 from each family group were subjected to one of two thermal treatments for
 a duration of 80 days. Rearing tank (Tank), sex (Sex), thermal treatment
 group (Treat) individual identifier (animal), parents (DAM & SIRE) and

 following thermal treatment, fish were euthanized and total mRNA extracted
 from liver tissues. Transcript abundance was estimated via quantitative
 real-time PCR. LinRegPCR was used to convert raw CT values into estimates
 of initial/starting mRNA concentrations (N0). Initial mRNA concentrations
 were standardized relative to the geometric mean of two reference genes
 (geomean.REFS). Standardized values of candidate genes occupy the final 12

title: Data from: Do hatchery-reared sea urchins pose a threat to genetic diversity in wild populations?

description: In salmonids, the release of hatchery-reared fish has been shown to cause
 irreversible genetic impacts on wild populations. However, although
 responsible practices for producing and releasing genetically diverse,
 hatchery-reared juveniles have been published widely, they are rarely
 implemented. Here, we investigated genetic differences between wild and
 early-generation hatchery-reared populations of the purple sea urchin
 Paracentrotus lividus (a commercially important species in Europe) to
 assess whether hatcheries were able to maintain natural levels of genetic
 diversity. To test the hypothesis that hatchery rearing would cause
 bottleneck effects (that is, a substantial reduction in genetic diversity
 and differentiation from wild populations), we compared the levels and
 patterns of genetic variation between two hatcheries and four nearby wild
 populations, using samples from both Spain and Ireland. We found that
 hatchery-reared populations were less diverse and had diverged
 significantly from the wild populations, with a very small effective
 population size and a high degree of relatedness between individuals.
 These results raise a number of concerns about the genetic impacts of
 their release into wild populations, particularly when such a degree of
 differentiation can occur in a single generation of hatchery rearing.
 Consequently, we suggest that caution should be taken when using
 hatchery-reared individuals to augment fisheries, even for marine species
 with high dispersal capacity, and we provide some recommendations to
 improve hatchery rearing and release practices. Our results further
 highlight the need to consider the genetic risks of releasing
 hatchery-reared juveniles into the wild during the establishment of
 restocking, stock enhancement and sea ranching programs.

title: Data from: Mimicking a rainfall gradient to test the role of soil microbiota for mediating plant species responses to drier conditions

description: Plant interactions with soil microbiota are important drivers of
 biodiversity and ecosystem function, but climate change can modify these
 interactions by directly altering the soil community, which can affect the
 direction and magnitude of such interactions. We manipulated water
 quantity and soil microbiota of two populations of three plant species
 that differ in their interactions with soil microbiota and assessed
 germination and biomass production under conditions that mimicked a
 rainfall gradient in SE Spain. We assessed the importance of soil
 microbiota from home and away (drier) sites for alleviating or
 exacerbating the effects of drier conditions. Our results suggest that
 home soil microbiota enhanced germination of the legume Trifolium
 stellatum. Conversely, we found that the grass, Lagurus ovatus, and the
 forb, Sisymbrium erysimoides, produced more biomass under moderate drying
 with soil microbiota from a drier site than with home soil microbiota,
 suggesting that dry-adapted soil microbiota alleviated the negative
 effects of drier conditions for these species. This maintenance of
 productivity with dry-adapted soil microbiota under drier conditions was
 found despite simultaneous reductions in leaf dry matter content and
 root-to-shoot ratio that would typically be less optimal trait responses
 under reduced water availability. Severe water limitation resulted in
 decreased plant biomass regardless of the plant species and soil inoculum,
 indicating a threshold effect whereby severe water limitation on growth
 supersedes the beneficial effects of soil microbiota. Overall, our results
 show that species identity, the severity of water limitation and soil
 microbiota interact to determine the response of plants to drier
 conditions.

title: Data from: Holokinetic drive: centromere drive in chromosomes without centromeres

description: Similar to how the model of centromere drive explains the size and
 complexity of centromeres in monocentrics (organisms with localized
 centromeres), our model of holokinetic drive is consistent with the
 divergent evolution of chromosomal size and number in holocentrics
 (organisms with non-localized centromeres) exhibiting holokinetic meiosis
 (holokinetics). Holokinetic drive is proposed to facilitate chromosomal
 fission and/or repetitive DNA removal (or any segmental deletion) when
 smaller homologous chromosomes are preferentially inherited or chromosomal
 fusion and/or repetitive DNA proliferation (or any segmental duplication)
 when larger homologs are preferred. The hypothesis of holokinetic drive is
 supported primarily by the negative correlation between chromosome number
 and genome size that is documented in holokinetic lineages. The supporting
 value of two older cross-experiments on holokinetic structural
 heterozygotes (the rush Luzula elegans and butterflies of the genus
 Antheraea) that indicate the presence of size-preferential homolog
 transmission via female meiosis for holokinetic drive is discussed, along
 with the potential negative consequences of holokinetic drive in
 comparison with centromere drive.

title: Data from: Population density and structure drive differential investment in pre- and postmating sexual traits in frogs

description: Sexual selection theory predicts a trade-off between premating (ornaments
 and armaments) and postmating (testes and ejaculates) sexual traits,
 assuming that growing and maintaining these traits is costly and that
 total reproductive investments are limited. The number of males in
 competition, the reproductive gains from investing in premating sexual
 traits, and the level of sperm competition are all predicted to influence
 how males allocate their finite resources to these traits. Yet, empirical
 examination of these predictions is currently scarce. Here, we studied
 relative expenditure on pre- and postmating sexual traits among frog
 species varying in their population density, operational sex ratio and the
 number of competing males for each clutch of eggs. We found that the
 intensifying struggle to monopolize fertilizations as more and more males
 clasp the same female to fertilize her eggs shifts male reproductive
 investment toward sperm production and away from male weaponry. This
 shift, which is mediated by population density and the associated level of
 male–male competition, likely also explains the trade-off between pre- and
 postmating sexual traits in our much broader sample of anuran species. Our
 results highlight the power of such a multi-level approach in resolving
 the evolution of traits and allocation trade-offs.
