title: Data from: Meaningful call combinations and compositional processing in the southern pied babbler

description: Language’s expressive power is largely attributable to its
 compositionality: meaningful words are combined into larger/higher-order
 structures with derived meaning. Despite its importance, little is known
 regarding the evolutionary origins and emergence of this syntactic
 ability. Although previous research has shown a rudimentary capability to
 combine meaningful calls in primates, because of a scarcity of comparative
 data, it is unclear to what extent analog forms might also exist outside
 of primates. Here, we address this ambiguity and provide evidence for
 rudimentary compositionality in the discrete vocal system of a social
 passerine, the pied babbler (Turdoides bicolor). Natural observations and
 predator presentations revealed that babblers produce acoustically
 distinct alert calls in response to close, low-urgency threats and
 recruitment calls when recruiting group members during locomotion. On
 encountering terrestrial predators, both vocalizations are combined into a
 “mobbing sequence,” potentially to recruit group members in a dangerous
 situation. To investigate whether babblers process the sequence in a
 compositional way, we conducted systematic experiments, playing back the
 individual calls in isolation as well as naturally occurring and
 artificial sequences. Babblers reacted most strongly to mobbing sequence
 playbacks, showing a greater attentiveness and a quicker approach to the
 loudspeaker, compared with individual calls or control sequences. We
 conclude that the sequence constitutes a compositional structure,
 communicating information on both the context and the requested action.
 Our work supports previous research suggesting combinatoriality as a
 viable mechanism to increase communicative output and indicates that the
 ability to combine and process meaningful vocal structures, a basic
 syntax, may be more widespread than previously thought.

title: Data from: Null alleles are ubiquitous at microsatellite loci in the Wedge Clam (Donax trunculus)

description: Recent studies have reported an unusually high frequency of nonamplifying
 alleles at microsatellite loci in bivalves. Null alleles have been
 associated with heterozygous deficits in many studies. While several
 studies have tested for its presence using different analytical tools, few
 have empirically tested for its consequences in estimating population
 structure and differentiation. We characterised 16 newly developed
 microsatellite loci and show that null alleles are ubiquitous in the wedge
 clam, Donax trunculus. We carried out several tests to demonstrate that
 the large heterozygous deficits observed in the newly characterised loci
 were most likely due to null alleles. We tested the robustness of
 microsatellite genotyping for population assignment by showing that
 well-recognised biogeographic regions of the south Atlantic and south
 Mediterranean coast of Spain harbour genetically different populations.

title: Data from: Plant and insect microbial symbionts alter the outcome of plant-herbivore-parasitoid interactions: implications for invaded, agricultural and natural systems

description: 1. Understanding how soil microbial communities influence plant
 interactions with other organisms, and how this varies with
 characteristics of the interacting organisms, is important for multiple
 systems. Solanum spp. are a suitable model for trophic interactions in
 studies of agricultural and natural systems and can also provide useful
 corollaries in invaded systems. This study examined the influence of soil
 mutualist arbuscular mycorrhizal (AM) fungi on growth of different Solanum
 types fed on by the potato aphid, Macrosiphum euphorbiae, in relation to
 presence of the aphid facultative endosymbiont Hamiltonella defensa. 2.
 Four Solanum types comprising two wild species, S. berthaultii and S.
 polyadenum, and two accessions of S. tuberosum, were grown with or without
 AM fungi and infested with one of four clonal lines of a single M.
 euphorbiae genotype (two with and two without H. defensa). Two experiments
 were conducted to i) characterise plant responses to AM fungi and aphids
 and ii) assess whether soil AM fungi could influence the success of the
 parasitoid wasp Aphidus ervi when attacking aphids reared on each Solanum
 type. 3. In both experiments, similar patterns of plant biomass were
 observed in relation to AM fungal and aphid treatments. Solanum biomass
 depended on plant type and aphid infection with H. defensa. Plants exposed
 to aphids harbouring H. defensa had smaller root biomass, and therefore
 total plant biomass, compared to plants infested with H. defensa-free
 aphids. M. euphorbiae performance varied with aphid clonal line, Solanum
 type and presence of AM fungi. 4. Parasitoid success, measured as the
 proportion of aphids from which a wasp emerged, was highest from aphids
 that had fed on plants colonised by AM fungi, although this result also
 varied with Solanum type and aphid clonal line. 5. Synthesis: The presence
 of soil AM fungi, combined with within-species plant and insect variation
 in key traits, can have subtle - but significant - effects on plant
 fitness and insect success. This study highlights the importance of
 exploring genotypic variation in plant and pest responses to soil
 microbiota to identify suitable biocontrol options.

title: Data from: The evolution of XY-recombination: sexually antagonistic selection versus deleterious mutation load

description: Recombination arrest between X and Y chromosomes, driven by sexually
 antagonistic genes, is expected to induce their progressive
 differentiation. However, in contrast to birds and mammals (which display
 the predicted pattern), most cold-blooded vertebrates have homomorphic sex
 chromosomes. Two main hypotheses have been proposed to account for this,
 namely high turnover rates of sex determining systems and occasional XY
 recombination. Using individual-based simulations, we formalize the
 evolution of XY recombination (here mediated by sex reversal; the
 “fountain-of-youth” model) under the contrasting forces of sexually
 antagonistic selection and deleterious mutations. The shift between the
 domains of elimination and accumulation occurs at much lower selection
 coefficients for the Y than for the X. In the absence of dosage
 compensation, mildly deleterious mutations accumulating on the Y depress
 male fitness, thereby providing incentives for XY recombination. Under our
 settings, this occurs via “demasculinization” of the Y, allowing
 recombination in XY (sex-reversed) females. As we also show, this
 generates a conflict with the X, which co-evolves to oppose sex reversal.
 The resulting rare events of XY sex reversal are enough to purge the Y
 from its load of deleterious mutations. Our results support the “fountain
 of youth” as a plausible mechanism to account for the maintenance of
 sex-chromosome homomorphy.

title: Data from: Isolation rearing does not constrain social plasticity in a family-living lizard

description: An animal’s social environment can be both dynamic and complex. Thus,
 social species often garner fitness benefits through being plastic in
 their social behavior. Yet, social plasticity can be constrained by an
 individual’s experience. We examined the influence of early social
 environment on social behavior in the tree skink (Egernia striolata), a
 family-living lizard. In the first phase of this study, we reared
 juveniles in two different social environments for 1.5 years: either in
 isolation or in unrelated pairs. We quantified each lizard’s sociability
 at four-month intervals using a standardized laboratory assay, and found
 that isolated lizards were more sociable, spending the assay closer to an
 adult female, than socially-reared lizards. In the second phase of this
 study (at the end of 1.5 years), we released all lizards into a
 semi-natural environment, observed their associations, and used social
 network analysis to quantify social behavior. During the initial six weeks
 post-release, we detected no differences in social behavior between
 rearing treatments. However, during the following six months differences
 emerged. Isolated lizards were more homogeneous in the strength of their
 associations than socially-reared lizards. Also, at first, isolated
 lizards associated more strongly than socially-reared lizards. Over time,
 isolated lizard associations became weaker and involved fewer lizards. In
 contrast, the level and number of associations of socially-reared lizards
 were stable over time. Our findings suggest that early experience
 influences tree skink social behavior but does not constrain social
 plasticity: isolation rearing did not limit their ability to respond to a
 novel social environment.

title: Data from: Strong sexual selection in males against a mutation load that reduces offspring production in seed beetles

description: Theory predicts that sexual reproduction can increase population viability
 relative to asexual reproduction by allowing sexual selection in males to
 remove deleterious mutations from the population without large demographic
 costs. This requires that selection acts more strongly in males than
 females and that mutations affecting male reproductive success have
 pleiotropic effects on population productivity, but empirical support for
 these assumptions is mixed. We used the seed beetle Callosobruchus
 maculatus to implement a three-generation breeding design where we induced
 mutations via ionizing radiation (IR) in the F0 generation, measured
 mutational effects (relative to non-irradiated controls) on an estimate of
 population productivity in the F1, and effects on sex-specific competitive
 lifetime reproductive success (LRS) in the F2. Regardless of whether
 mutations were induced via F0 males or females, they had strong negative
 effects on male LRS, but a non-significant influence on female LRS,
 suggesting that selection is more efficient in removing deleterious
 alleles in males. Moreover, mutations had seemingly shared effects on
 population productivity and competitive LRS in both sexes. Thus, our
 results lend support to the hypothesis that strong sexual selection on
 males can act to remove the mutation load on population viability, thereby
 offering a benefit to sexual reproduction.

title: Data from: Life history strategy and everyday word use

description: Research by Sherman et al. (Journal of Personality and Social Psychology,
 105, 873–888, 2013) has shown that, in speech during clinical-style
 interviews, life history strategy (LHS) was correlated with variation in
 the use of 16–19 word categories from the Linguistic Inquiry and Word
 Count program. However, links between individual difference variables and
 word use have been shown to vary as a function of communication context.
 Therefore, I sought to replicate their results using speech recorded
 during participants’ daily life via the Electronically Activated Recorder.
 I also used (1) observer ratings rather than self-ratings of the
 California Adult Q-Sort (CAQ) items as a measure of LHS, (2) the
 self-report Arizona Life History Battery (ALHB) as an additional measure
 of LHS, and (3) Bayesian multi-level aggregated binomial regressions as a
 complementary analytical technique to conventional correlations. In
 general, the Sherman et al. results were replicated, particularly with
 respective to distinctive (corrected for normativeness) LHS. People
 pursuing a slower distinctive LHS produced proportionately fewer swear
 words, sexual words, and affect words (particularly negative emotion and
 anger words), and more work-related words. They also produced fewer words
 overall. After controlling for distinctive LHS, women were more talkative
 than men. Associations between the ALHB and word use were weaker than
 those between the CAQ and word use.

title: Data from: Bayesian estimation of the global biogeographical history of the Solanaceae

description: Aim: The tomato family Solanaceae is distributed on all major continents
 except Antarctica and has its centre of diversity in South America. Its
 worldwide distribution suggests multiple long-distance dispersals within
 and between the New and Old Worlds. Here, we apply maximum likelihood (ML)
 methods and newly developed biogeographical stochastic mapping (BSM) to
 infer the ancestral range of the family and to estimate the frequency of
 dispersal and vicariance events resulting in its present-day distribution.
 Location: Worldwide. Methods: Building on a recently inferred
 megaphylogeny of Solanaceae, we conducted ML model fitting of a range of
 biogeographical models with the program ‘BioGeoBEARS’. We used the
 parameters from the best fitting model to estimate ancestral range
 probabilities and conduct stochastic mapping, from which we estimated the
 number and type of biogeographical events. Results: Our best model
 supported South America as the ancestral area for the Solanaceae and its
 major clades. The BSM analyses showed that dispersal events, particularly
 range expansions, are the principal mode by which members of the family
 have spread beyond South America. Main conclusions: For Solanaceae, South
 America is not only the family's current centre of diversity but also
 its ancestral range, and dispersal was the principal driver of range
 evolution. The most common dispersal patterns involved range expansions
 from South America into North and Central America, while dispersal in the
 reverse direction was less common. This directionality may be due to the
 early build-up of species richness in South America, resulting in large
 pool of potential migrants. These results demonstrate the utility of BSM
 not only for estimating ancestral ranges but also in inferring the
 frequency, direction and timing of biogeographical events in a
 statistically rigorous framework.

title: Data from: Beak color dynamically signals changes in fasting status and parasite loads in king penguins

description: Dynamic ornamental signals that vary over minutes, hours or weeks can
 yield continuous information on individual condition (e.g., energy
 reserves or immune status), and may therefore be under strong social
 and/or sexual selection. In vertebrates, the coloration of the integument
 is often viewed as a dynamic ornament, which in birds can be apparent in
 the beak. King penguins (Aptenodytes patagonicus) are monomorphic seabirds
 that possess conspicuous yellow–orange (YO) and ultraviolet (UV) beak
 spots that are used by both males and females in mate choice. We studied
 the dynamicity of beak spot sexual traits, and to what extent they
 reflected changes in individual condition in fasting king penguins and in
 penguins treated with an anti-parasitic drug. We also describe the
 maturation of this colorful ornament during the yearly catastrophic moult.
 On a time-scale of days to weeks, beak spot coloration changed in response
 to fasting and experimental changes in parasite load. Beak spot UV
 brightness decreased over a 10-day fast in breeding birds. For birds
 caught during courtship and held in captivity YO chroma decreased after a
 24-day fast. Birds that were treated with an anti-parasitic solution
 showed an increase in UV coloration after parasite removal. Altogether,
 our results show that beak spot coloration is a dynamic ornament that
 reflects multiple dimensions of changes in individual condition in
 breeding-fasting penguins.

title: Data from: The evolutionary dynamics of adaptive virginity, sex-allocation and altruistic helping in haplodiploid animals

description: In haplodiploids, females can produce sons from unfertilized eggs without
 mating. However, virgin reproduction is usually considered to be a result
 of a failure to mate, rather than an adaptation. Here we build an
 analytical model for evolution of virgin reproduction, sex-allocation, and
 altruistic female helping in haplodiploid taxa. We show that when mating
 is costly (e.g. when mating increases predation risk), virginity can
 evolve as an adaptive female reproductive strategy. Furthermore, adaptive
 virginity results in strongly divergent sex-ratios in mated and virgin
 queen nests (‘split sex ratios’), which promotes the evolution of
 altruistic helping by daughters in mated queen nests. However, when
 helpers evolve to be efficient and increase nest production significantly,
 virgin reproduction is selected against. Our results suggest that adaptive
 virginity could have been an important stepping stone on the pathway to
 eusociality in haplodiploids. We further show that virginity can be an
 adaptive reproductive strategy also in primitively social haplodiploids if
 workers bias the sex ratio toward females. By remaining virgin, queens are
 free to produce sons, the more valuable sex in a female-biased population.
 Our work brings a new dimension to the studies linking reproductive
 strategies with social evolution.

title: Ipseity Daily Data

description: At what rate do individuals say they are X?

Begining on 2025-07-08, I surveyed a small random sample of American adults on a daily cadence.  They responded to many items of the form: Does <signifier> describe you today?

The file ipseity-daily-aggregated.csv in this repository contains the aggregated results through 2025-07-28.  The columns are as follows:



signifier - a word, phrase or emoji

yes_count - the number of respondents who answered yes (aggregated all-time).

no_count - the number of respondents who answered no (aggregated all-time).

prevalence_per_10k - an estimate of the prevalence per 10,000.  If we were to survey 10,000 American adults, how many would we expect to respond yes to this signifier?  The number is calculated as yes_count / (yes_count + no_count) * 10,000.

earliest_obs_date - this date represents the first time this particular signifier was ever displayed to a respondent.  Signifiers are chosen with stochasticity from a long list; new signifiers are sometimes added, old signifiers are sometimes deleted, and a signifier may be moved higher or lower in priority for sampling.

latest_obs_date - the date closest to the present date on which signifier was most recently presented to a respondent.
