title: The role of population size in folk tune complexity

description: Demography, particularly population size, plays a key role in cultural
 complexity. However, the relationship between population size and
 complexity appears to vary across domains: while studies of technology
 typically find a positive correlation, the opposite is true for language,
 and the role of population size in complexity in the arts remains to be
 established. Here, we investigate the relationship between population size
 and complexity in music using Irish folk session tunes as a case study.
 Using analyses of a large online folk tune dataset, we show that popular
 tunes played by larger communities of musicians have diversified into a
 greater number of different versions which encompass more variation in
 melodic complexity compared with less popular tunes. However, popular
 tunes also tend to be intermediate in melodic complexity and variation in
 complexity is lower than expected given the increased number of tune
 versions. We also find that user preferences for individual tune versions
 are more skewed in popular tunes. Taken together, these results suggest
 that while larger populations create more frequent opportunities for
 musical innovation, they encourage convergence upon intermediate levels of
 melodic complexity due to a widespread inverse U-shaped relationship
 between complexity and aesthetic preference. We explore the assumptions
 underlying our empirical analyses further using simple simulations of tune
 diffusion through populations of different sizes, finding that a
 combination of biased copying and structured populations appears most
 consistent with our results. Our study demonstrates a unique relationship
 between population size and cultural complexity in the arts, confirming
 that the relationship between population size and cultural complexity is
 domain-dependent, rather than universal.

title: Prevalence of vector-borne pathogens in reproductive and non-reproductive tissue samples from free-roaming domestic cats in the South Atlantic USA

description: Reservoir to multiple species of zoonotic pathogens, free-roaming cats
 (FRCs) interact with domestic and wild animals, vectors, and humans. To
 assess the potential for feline vector-borne pathogens to be vertically
 transmitted, this study surveyed eartip and reproductive tissues of FRCs
 from two locations in the South Atlantic United States for Anaplasma,
 Bartonella, Ehrlichia, hemotropic Mycoplasma, and Rickettsia species. We
 collected ovary (n = 72), uterus (n = 54), testicle (n = 74), and eartip
 (n = 73) tissue from 73 cats, and fetal (n = 20) and placental (n = 19)
 tissue from 11 queens. Pathogen DNA was amplified utilizing qPCR,
 confirmed by sequencing. Cats were more frequently Bartonella henselae
 positive on reproductive tissues (19%, 14/73) than ear tip (5%, 4/73; p =
 0.02). B. henselae was amplified from fetus (20%, 4/20) and placenta
 samples (11%, 2/19). Bartonella spp. infection was more common in cats
 from North Carolina (76%, 26/34) than Virginia (13%, 5/39; p &lt;
 0.0001). Fourteen percent (10/73) of both ear tip and reproductive tissues
 were positive for hemotropic Mycoplasma spp. Anaplasma, Ehrlichia, and
 Rickettsia spp. DNA was not amplified from any cat/tissue. These findings
 suggest that B. henselae preferentially infected cats’ reproductive tissue
 and reinforces the importance of investigating the potential for B.
 henselae vertical transmission or induction of reproductive failure.

title: Data from: Parental care amplifies changes in offspring production in a disturbed environment

description: Recruitment is usually negatively density-dependent with fewer offspring
 surviving when more are produced. Parental care could alter the pattern as
 behaviours that maximize individual fitness are not necessarily adaptive
 at the population level. We manipulated the number of eggs spawned into
 the nests of male threespine stickleback, and found egg survival to be
 positively density-dependent. This reversed negative density-dependent
 survival observed in the absence of parental care. The reversal was caused
 my males investing more in parental care when receiving more eggs, while
 favouring future reproductive opportunities when receiving few eggs.
 Density-dependent parental care thus amplified changes in offspring
 production in relation to number of eggs spawned. Such amplification may
 occur in disturbed environments where human activities have altered female
 fecundity and males may receive more or less eggs than expected. The
 optimal balancing between present and future parental investment can then
 be distorted, resulting in maladaptive parental behaviour that reduces
 offspring survival. These results suggest that behaviours that have
 evolved to maximize individual fitness under pristine conditions can
 become mal-adaptive under disturbed conditions and influence the
 recruitment of offspring into a population. Considering that human
 activities are rapidly transforming environments, such mal-adaptive
 behavioural responses could be common and magnify negative effects of
 human activities on population dynamics.

title: Comparing the nutritional status of children and adolescents from North Korean defector families and South Korean families

description: Objective: This study aimed to investigate the nutritional status of
 children and adolescents from North Korean defector (NKD) families who are
 currently living in South Korea (SK) and compared with the status of those
 from SK families. Design: A cross-sectional study comparing the prevalence
 of malnutrition, overweight, and obesity between children and adolescents
 from NKD families and SK families. Setting: Children and adolescents from
 NKD families were interviewed face-to-face directly, whereas the data
 about those from SK families acquired by using 2017 Korea National Health
 and Nutrition Examination Survey(KNHANES). Their nutritional status were
 estimated using the 2017 Korean National Growth Charts for children and
 adolescents Participants: The total number of children and adolescents was
 2,136 consisting of 527 subjects from the NKD families and 1,609 subjects
 from the SK families. Results: The overall prevalence of stunting,
 wasting, underweight, overweight, and obesity in NKD group was 8.9%,
 10.2%, 10.4%, 11.2%, and 12.2% respectively, and 1.9%, 7.1%, 5.9%, 9.2%,
 and 9.3%, respectively, in SK families. The NKD group showed significantly
 higher prevalence than SK group in stunting(p&lt;0.001),
 wasting(p=0.014), underweight(p&lt;0.001), obesity(p=0.041) but not in
 overweight. Conclusions: The nutritional status of children and
 adolescents form NKD families was worse than that of those from SK
 families, and also higher prevalence of obesity.
description: Children and adolescents of the NKD families were defined as
 those aged 0–18 years who are currently being raised in SK and were born
 in families where at least one parent is an NKD. A total of 527
 participants were recruited from local Hana Centers, alternative schools,
 and non-governmental organizations (NGOs) across SK between September 2017
 and December 2019. Among the total of 8,127
 participants of 2017 Korea National Health and Nutrition Examination
 Survey (2017 KNHANES), children and adolescents of the SK families were
 defined as 1,609 children and adolescents aged 0–18 years.

title: UCE alignments and phylogenetic trees

description: Genomic data continue to advance our understanding of species limits and
 biogeographic patterns. However, there is still no consensus regarding
 appropriate methods of phylogenomic analysis that make the best use of
 these heterogeneous data sets. In this study, we used thousands of
 ultraconserved element (UCE) loci from alligator lizards in the genus
 Gerrhonotus to compare and contrast species trees inferred using multiple
 contemporary methods and provide a timeframe for biological
 diversification across the Mexican Transition Zone (MTZ). Concatenated
 maximum likelihood (ML) and Bayesian analyses provide highly congruent
 results, with differences limited to poorly supported nodes. Similar
 topologies were inferred from coalescent analyses in BPP and SVDquartets,
 albeit with lower support for some nodes. All divergence times fell within
 the Miocene, linking speciation to local Neogene vicariance and/or global
 cooling trends following the mid-Miocene Climatic Optimum. We detected a
 high level of genomic divergence for a morphologically distinct species
 restricted to the arid mountains of northeastern Mexico, and erected a new
 genus to better reflect evolutionary history. In sum, our results further
 advocate leveraging the strengths and weaknesses of concatenation and
 coalescent methods, provide evidence for old divergences for alligator
 lizards, and indicate that the MTZ continues to harbor substantial
 unrecognized diversity.

title: Evolutionary and plastic variation in larval growth and digestion reveal the complex underpinnings of size and age at maturation in dung beetles

description: Age and size at maturity are key life history components, yet the
 proximate underpinnings that mediate intra- and interspecific variation in
 life history remain poorly understood. We studied the proximate
 underpinnings of species differences and nutritionally plastic variation
 in adult size and development time in four species of dung beetles.
 Specifically, we investigated how variation in insect growth mediates
 adult size variation, tested whether fast juvenile growth trades-off with
 developmental stability in adult morphology, and quantified plastic
 responses of digestive systems to variation in food quality. Contrary to
 the common size-development time trade-off, the largest species exhibited
 by far the shortest development time. Correspondingly, species diverged
 strongly in the shape of growth trajectories. Nutritionally plastic
 adjustments to growth were qualitatively similar between species but
 differed in magnitude. Although we expected rapid growth to induce
 developmental costs, neither instantaneous growth rates nor the duration
 of larval growth were related to developmental stability in the adult.
 This renders the putative costs of rapid growth enigmatic. We further
 found that larvae that encounter a challenging diet develop a larger
 midgut and digest more slowly than animals reared on a more nutritious
 diet. These data are consistent with the hypothesis that larvae invest
 into a more effective digestive system when exposed to low-quality
 nutrition, but suggest that species may diverge readily in their reliance
 on these mechanisms. More generally, our data highlight the complex, and
 often hidden, relationships between immature growth and age and size at
 maturation even in ecologically similar species.

title: Distinguishing between unreliability and dishonesty: a comparative study of aggressive communication in crayfish

description: A major challenge in the study of animal communication is distinguishing
 whether signals convey honest or dishonest information. Biologists infer
 the honesty of a signal from its correlation with the information being
 signaled (e.g., fecundity or fighting ability) — the better the
 correlation, the more honest the signal. However, this view of signaling
 potentially conflates unreliable indicators with dishonest signals. Just
 because a trait conveys unreliable information does not mean that the
 structure serves as a dishonest signal; developmental noise, genetic
 drift, and environmental constraints can reduce the covariation between a
 putative signal and an organism’s quality. Moreover, a trait must
 influence the behavior of other organisms to qualify as a signal. We
 studied how a putative signal, claw size, affects physical performance and
 social dominance in three species of stream-dwelling crayfish, which fight
 routinely over resources. For comparison, we measured the relationship
 between claw size and claw strength in three species of burrowing
 crayfish, which do not fight. In all species, crayfish with larger claws
 were not necessarily stronger, indicating that claw size poorly indicates
 claw strength. However, claw size is unlikely to function as a dishonest
 signal of fighting ability in these species for two reasons. First, claw
 size unreliably indicates claw strength in both the stream-dwelling
 species and the burrowing species. Second, relative claw size poorly
 predicted whether stream-dwelling crayfish would escalate aggression,
 questioning whether claw size serves as a signal. Instead, stream-dwelling
 crayfish escalated aggression based on their relative body size. Our
 results highlight the importance of observing behavior when determining
 the honesty of a signal. As such, future studies must distinguish between
 phenotypes that are unreliable indicators (or reliable indicators) from
 phenotypes that have been selected for dishonest (or honest)
 signaling.

title: Data from: Traits mediate niches and co-occurrences of forest beetles in ways that differ among bioclimatic regions

description: Aim To investigate the role of traits in beetle community assembly and
 test for consistency in these effects among several bioclimatic regions.
 We asked (1) whether traits predicted species’ responses to environmental
 gradients (i.e., their niches), (2) whether these same traits could
 predict co-occurrence patterns, and (3) how consistent were niches and the
 role of traits among study regions. Location Boreal forests in Norway and
 Finland, temperate forests in Germany. Methods We complied capture records
 of 468 wood-living beetle species from the three regions, along with nine
 morphological and ecological traits. Eight climatic and forest covariates
 were also collected. We used Bayesian hierarchical joint species
 distribution models to estimate the influence of traits and phylogeny on
 species’ niches. We also tested for correlations between species
 associations and trait similarity. Finally, we compared species niches and
 the effects of traits among study regions. Results Traits explained some
 of the variability in species’ niches, but their effects differed among
 study regions. However, substantial phylogenetic signal in species niches
 implies that unmeasured but phylogenetically structured traits have a
 stronger effect. Degree of trait similarity was correlated with species
 associations but depended idiosyncratically on the trait and region.
 Species niches were much more consistent – widespread taxa often responded
 similarly to an environmental gradient among regions. Main conclusions The
 inconsistent effects of traits among regions limits their current use in
 understanding beetle community assembly. Phylogenetic signal in niches,
 however, implies that better predictive traits can eventually be
 identified. Consistency of species niches among regions means niches may
 remain relatively stable under future climate and land use changes; this
 lends credibility to predictive distribution models based on future
 climate projections but may imply that species’ scope for short-term
 adaptation is limited.

title: SnRNA sequencing defines signaling by RBC-derived extracellular vesicles in the murine heart

description: Extracellular vesicles (EVs) mediate intercellular signaling by
 transferring their cargo to recipient cells, but the functional
 consequences of signaling are not fully appreciated. Red blood cell
 (RBC)-derived EVs are abundant in circulation and have been implicated in
 regulating immune responses. Here, we use a transgenic mouse model for
 fluorescence-based mapping of RBC-EV recipient cells to assess the role of
 this intercellular signaling mechanism in heart disease. Using
 fluorescent-based mapping, we detected an increase in RBC-EV-targeted
 cardiomyocytes in a murine model of ischemic heart failure. Single cell
 nuclear RNA sequencing of the heart revealed a complex landscape of
 cardiac cells targeted by RBC-EVs, with enrichment of genes implicated in
 cell proliferation and stress signaling pathways compared to non-targeted
 cells. Correspondingly, cardiomyocytes targeted by RBC-EVs more frequently
 express cellular markers of DNA synthesis, suggesting the functional
 significance of EV-mediated signaling. In conclusion, our mouse model for
 mapping of EV-recipient cells reveals a complex cellular network of RBC-EV
 mediated intercellular communication in ischemic heart failure and
 suggests a functional role for this mode of intercellular signaling.
description: Previous studies have demonstrated the importance of
 extracellular vesicle (EV) cargo RNAs, notably miRNAs in modulating
 recipient cell function. We therefore sought to determine the small
 RNA content of RBC-EVs and their possible regulation of pathways
 highlighted by the snRNA seq described above. Human red blood cell
 (RBC)-EVs were isolated using immunoaffinity-bead-based flow sorting with
 a validated antibody against Glycophorin-A (CD235a). We explored RBC-EV
 content in a clinically well-characterized biorepository of human plasma
 from patients with myocardial infarction (MI, n=5) and control patients
 referred for supraventricular tachycardia (SVT, n=5). After confirming the
 specificity of the Glycophorin-A positive EV isolation method using flow
 cytometry, microscopy, and digital PCR for RBC-enriched RNAs, we performed
 small RNA-seq to analyze RNA content in Glycophorin-A
 (CD235a)-immunopositive EVs from the plasma of human subjects. After
 analyzing pooled RNA-seq data for samples that passed minimal QC, we
 identified a total of 105 distinct miRNAs in the plasma derived
 RBC-EVs.

title: The role of howler monkeys (Alouatta caraya) in the primary succession of the Paraná flooded forest (Argentina)

description: In disturbed forests, Atelidae primates, such as howler monkeys, are known
 to play a key role in the dynamics of secondary succession. However,
 little is known about their role in primary succession. Thus, the aim of
 the present study was to evaluate the role of the howler monkey Alouatta
 caraya in the primary succession dynamics of the Paraná flooded forest, in
 northeastern Argentina. This was achieved by studying the recruitment of
 saplings in the latrines of A. caraya groups inhabiting the forest in the
 first stages of succession and the distribution of plant species in
 relation to the age of the forest. The results showed that: (a) young
 forest areas were dominated by tree species dispersed by water, wind,
 birds, bats and fishes, whereas older forest areas were dominated by
 species dispersed by A. caraya, with individuals of some species present
 in young forests; (b) the floristic composition of saplings growing in A.
 caraya latrines of young forest areas was similar to that of old forest
 areas; and (c) saplings growing in young forest areas were heavily
 associated with A. caraya latrines and corresponded to species from older
 forest areas. The results allow the conclusion that A. caraya plays a role
 in the last phase of primary succession of the Paraná flooded forest, as
 well as in contributing to an increase in the structural complexity and
 species diversity in the young areas of the Paraná islands.
description: The species composition of the forest was evaluated in both young
 and old areas of the "Brasilera" island in Paraná River.
 Twenty-five plots of 20 x 20 m were located at random in the forest of the
 young areas of the island (characterized by presence of
 <i>Tessaria integrifolia</i> and
 <i>Salix humboltiana,</i> (Marchetti et al. 2013, Brumnich et
 al. 2019)), whereas the other 25 were located in the central and southern
 bars of the island to sample old forests. All trees with more than 10 cm
 of diameter at breast height were recorded. To find latrines of
 <em>Alouatta caraya</em> monkeys, three transects of 500 m
 long were used in the old forests and one in the young area. Eighteen
 latrines were found in the old forests and ten in the young area. All
 saplings, small individuals with less than a third diameter than adult
 trees, higher than 25 cm growing in them were recorded.
