title: A coacervate-based mixed-conducting binder for high-power, high-energy batteries

description: This data set accompanies the article "A Coacervate-Based
 Mixed-Conducting Binder for High-Power, High-Energy Batteries"
 published in ACS Energy Letters in 2023
 (https://doi.org/10.1021/acsenergylett.3c00829). The article demonstrates
 a strategy for imparting electronic and ionic conductivity to battery
 binders, while also maintain facile processing capability. 
 Polymer binders add crucial structural integrity to lithium ion battery
 composite cathodes, but industry standard binders, such as polyvinylidene
 fluoride (PVDF), are insulating to ions and electrons, detrimentally
 adding resistance to the overall system. In this work, we use
 electrostatics to stabilize a blend of a charged conjugated polymer with
 an oppositely charged polyelectrolyte, providing a processable, stable
 binder with high ionic and electronic conduction. Using LiFePO4 cathodes
 as a model system, we show significant improvement in rate capability and
 stability, with the conducting binder enabling a 39% utilization at 6C
 compared to 1.6% when PVDF is the binder. Additionally, the conducting
 binder affords a 63% capacity retention over 400 C/2 cycles, compared to
 only a 6% retention over 400 cycles when PVDF is the binder. These results
 show that electrostatically stabilized complexation is a promising
 strategy to integrate both electronic and ionic conductivity into a
 binder, while simultaneously maintaining stability and processability.

title: Data from: Precipitation timing and soil substrate drive phenology and fitness of Arabidopsis thaliana in a Mediterranean environment

description: In Mediterranean climates, the timing of seasonal rains determines
 germination and flowering phenology, which in turn may affect fitness. As
 climate change alters seasonal precipitation patterns, it is important to
 ask how these changes will affect the phenology and fitness of plant
 populations. We addressed this question experimentally with the annual
 plant species Arabidopsis thaliana. In a first experiment, we manipulated
 the date of rainfall onset and recorded germination phenology on sand and
 soil substrates. In a second experiment, we manipulated germination date,
 growing season length, and mid-season drought to measure their effects on
 flowering time and fitness. Within each experiment, we manipulated seed
 dormancy and flowering time using multilocus near-isogenic lines
 segregating strong and weak alleles of the seed dormancy gene DOG1 and the
 flowering time gene FRI.  We synthesized germination phenology
 data from the first experiment with fitness functions from the second
 experiment to project population fitness under different seasonal rainfall
 scenarios. Germination phenology tracked rainfall onset but was slower and
 more variable on sand than on soil. Many seeds dispersed on sand in
 spring, and summer delayed germination until the cooler temperatures of
 autumn. The high-dormancy DOG1 allele also prevented immediate germination
 in spring and summer. Germination timing strongly affected plant fitness.
 Fecundity was highest in the October germination cohort and declined to
 extremely low levels in spring germinants. The late flowering FRI allele
 had lower fecundity.  Projections of population fitness revealed
 that: 1) Later onset of autumn rains will negatively affect population
 fitness. 2) Slow, variable germination on sand buffers populations against
 fitness impacts of variable spring and summer rainfall. 3) Seasonal
 selection favors high dormancy and early flowering genotypes in a
 Mediterranean climate.  In particular, the high-dormancy DOG1
 allele delayed germination of spring-dispersed fresh seeds until more
 favorable early fall conditions, resulting in higher fecundity and
 projected population fitness. These findings suggest that Mediterranean
 annual plant populations are vulnerable to changes in seasonal
 precipitation, especially in California where rainfall onset is already
 occurring later. The fitness advantage of highly dormant, early flowering
 genotypes helps explain the prevalence of this strategy in Mediterranean
 populations.

title: Molecular-scale substrate anisotropy, crowding, and division drive collective behaviors in cell monolayers

description: The ability of cells to reorganize in response to external stimuli is
 important in areas ranging from morphogenesis to tissue engineering. While
 nematic order is common in biological tissues, it typically only extends
 to small regions of cells interacting via steric repulsion. On isotropic
 substrates, elongated cells can co-align due to steric effects, forming
 ordered but randomly oriented finite-size domains. However, we have
 discovered that flat substrates with nematic order can induce global
 nematic alignment of dense, spindle-like cells, thereby influencing cell
 organization and collective motion and driving alignment on the scale of
 the entire tissue. Remarkably, single cells are not sensitive to the
 substrate’s anisotropy. Rather, the emergence of global nematic order is a
 collective phenomenon that requires both steric effects and
 molecular-scale anisotropy of the substrate. To quantify the rich set of
 behaviors afforded by this system, we analyze velocity, positional and
 orientational correlations for several thousand cells over days. The
 establishment of global order is facilitated by enhanced cell division
 along the substrate’s nematic axis, and associated extensile stresses that
 restructure the cells’ actomyosin networks. Our work provides a new
 understanding of the dynamics of cellular remodeling and organization
 amongst weakly interacting cells.

title: Dataset for: Intraspecific size shifts in generalist bumblebees and flowers lead to low functional consequences

description: Body size is a trait that can affect plant-pollinator interaction
 efficiency and plant reproductive success. We explored the impact of
 intraspecific size shifts on the interactions between pollinators and
 flowering plants under controlled conditions. We considered two
 development conditions leading to the production of large and small
 individual flowers of Borago officinalis and Echium plantagineum. We also
 used the natural variability of worker size within bumblebee colonies to
 isolate small and large workers. We performed a fully crossed experiment
 with the two flower sizes of each plant species, and the two sizes of
 bumblebee workers. Our results show that the size of both partners did not
 affect bee foraging behavior in most of the evaluated parameters, and both
 bee sizes were equally efficient in depositing pollen. Significant
 differences were found only in the pollen deposition across the life of a
 flower in small flowers of B. officinalis, with the greatest quantity of
 pollen deposited by small bees. We did not find a relationship between
 pollinator size and plant fitness. Our results suggest that generalist
 plant-pollinator interactions may be resilient to future potential
 mismatches in the size of the partners, but remain to be tested if they
 are still resilient under the new environmental conditions resulting from
 global changes.

title: Sex and background risk influence responses to acute predation risk in Trinidadian guppies

description: Intraspecific sex differences in morphology, physiology, and behaviour are
 widespread among taxa. However, despite their fundamental importance, they
 have been relatively understudied in the context of risk assessment. For
 instance, with Trinidadian guppies (Poecilia reticulata), there has been a
 bias towards the exclusive use of females, as males are thought to be less
 responsive to acute predation threats. However, there is little empirical
 evidence supporting this assumption. Moreover, the antipredator behaviour
 of male guppies has been unexplored, perhaps resulting in the
 over-generalization of female behaviour to both sexes in previous studies.
 Here, we conducted laboratory experiments involving wild-caught and
 laboratory-reared guppies. In Experiment 1, shoals of either male or
 female guppies from a high predation population were tested for their
 response to alarm cues, novel odour, or a water control. We found that
 while female shoals exhibited strong antipredator responses to alarm cues
 and neophobic responses to novel odour, male shoals exhibited only a weak
 response to alarm cues and no evidence of neophobia. In Experiment 2, we
 exposed male and female guppies to high or low predation risk and then
 tested individuals for their responses to alarm cues, novel odour, or a
 water control. Regardless of background risk, males did not respond to any
 stimulus. In contrast, low-risk females exhibited antipredator responses
 toward alarm cues and those from high background risk displayed neophobia.
 Our results suggest that females are more cautious when encountering an
 acute predation risk, highlighting the importance of accounting for both
 sexes in studies on predation.

title: Data for: Precipitation gradients drive high tree species turnover in the woodlands of eastern and southern Africa

description: Savannas cover one-fifth of the Earth’s surface, harbour substantial
 biodiversity, and provide a broad range of ecosystem services to hundreds
 of millions of people. The community composition of trees in tropical
 moist forests varies with climate, but whether the same processes
 structure communities in disturbance-driven savannas remains relatively
 unknown. We investigate how biodiversity is structured over large
 environmental and disturbance gradients in woodlands of eastern and
 southern Africa. We use tree inventory data from the Socio-Ecological
 Observatory for Studying African Woodlands (SEOSAW) network, covering 755
 ha in a total of 6780 plots across nine countries of eastern and southern
 Africa, to investigate how alpha, beta, and phylogenetic diversity vary
 across environmental and disturbance gradients. We find strong
 climate-richness patterns, with precipitation playing a primary
 role in determining patterns of tree richness and high turnover across
 these savannas. Savannas with greater rainfall contain more tree species,
 suggesting that low water availability places distributional limits on
 species, creating the observed climate-richness patterns. Both fire and
 herbivory have minimal effects on tree diversity, despite their role in
 determining savanna distribution and structure. High turnover of tree
 species, genera, and families is similar to turnover in seasonally dry
 tropical forests of the Americas, suggesting this is a feature of semiarid
 tree floras. The greater richness and phylogenetic diversity of wetter
 plots show that broad-scale ecological patterns apply to
 disturbance-driven savanna systems. High taxonomic turnover suggests that
 savannas from across the regional rainfall gradient should be protected if
 we are to maximise the conservation of unique tree communities.

title: Data from: Local adaptation and future climate vulnerability in a wild rodent

description: As climate change continues, species pushed outside their physiological
 tolerance limits must adapt or face extinction. When change is rapid,
 adaptation will largely harness ancestral variation, making the
 availability and characteristics of that variation of critical importance.
 Here, we used whole-genome sequencing and genetic-environment association
 analyses to identify adaptive variation and its significance in the
 context of future climates in an iconic small mammal system. We found that
 peripheral populations of bank vole in Britain are already at the extreme
 bounds of potential genetic adaptation and may require an influx of
 adaptive variation in order to persist. Analyses of adaptive loci suggest
 regional differences in climate variables select for traits that influence
 patterns of population adaptive resilience, including genes associated
 with antioxidant defence, and support a pattern of thermal/hypoxic
 cross-adaptation. Understanding potential shifts in genomic composition in
 response to climate change may be key to predicting the fate of
 biodiversity in a future, warmer world.

title: A feasibility randomized controlled superiority trial of fluticasone-vilanterol once daily use for the treatment of mild asthma in adults

description: Objectives Current international guidelines recommend using a combination
 of Long-Acting Beta-Agonists and Inhaled Corticosteroids (LABA+ICS)
 therapy for symptomatic mild asthma. However, this change has yet to be
 widely implemented in the Middle East. The objective of this pilot study
 is to assess the feasibility (recruitment and retention rates) of
 conducting a future definitive RCT to investigate the effectiveness of
 fluticasone-vilanterol (LABA+ICS) in the management of mild asthma in
 adults, compared with usual care.  Design This 8-month parallel
 two-arm pilot trial took place in the Kingdom of Bahrain. We randomly
 assigned 18 patients with mild asthma in a 1:1 ratio to the treatment
 (n=10) or usual care (n=8) arms. The treatment group received daily
 LABA+ICS therapy while the usual care group continued as required SABA or
 SABA+ICS combination. The main outcome measures were descriptors of study
 feasibility (recruitment and retention rates). We also compared unblinded
 outcome assessment of asthma control score, quality of life, and the
 number of asthma exacerbations experienced by patients in both arms.
 Results A total of 18 patients were recruited from a single primary
 healthcare center and randomized by remote web-based allocation into
 intervention (n=10) and usual care (n=8) groups. The baseline
 characteristics of participants did not differ significantly across the
 two arms at the start of the trial. Because of slow recruitment and
 limited funding, the study didn’t meet our recruitment target but did
 successfully meet our retention criteria. At 32 weeks, the analysis
 indicated significant improvement in asthma control scores in the
 intervention arm (1.31 vs 2.91; 95% CI [0.72, 2.44];
 P-value=0.003), but no significant differences were noted in
 quality-of-life scores (P-value=0.197) compared to the baseline levels.
 There were no significant differences in post-intervention asthma control
 mean score (P-value=0.361) or QoL mean score (P-value=0.337) between the
 two arms after adjustment for pre-intervention scores. Conclusions This
 pilot RCT indicates that a definitive RCT is feasible in a primary
 healthcare setting in Bahrain. In a definitive trial, we recommend
 increasing the recruitment rate by relaxing eligibility criteria,
 extending the timeline, and increasing the number of sites for
 recruitment. Additionally, outcomes of this pilot trial suggest that
 LABA+ICS is a feasible, acceptable, safe, and effective intervention for
 the management of mild asthma in a Middle Eastern context.

title: Differences in boundary behavior in the 3D vertex and Voronoi models

description: An important open question in the modeling of biological tissues is how to
 identify the right scale for coarse-graining, or equivalently, the right
 number of degrees of freedom. For confluent biological tissues, both
 vertex and Voronoi models, which differ only in their representation of
 the degrees of freedom, have effectively been used to predict behavior,
 including fluid-solid transitions and cell tissue compartmentalization,
 which are important for biological function. However, recent work in 2D
 has hinted that there may be differences between the two models in systems
 with heterotypic interfaces between two tissue types, and there is a
 burgeoning interest in 3D tissue models. Therefore, we compare the
 geometric structure and dynamic sorting behavior in mixtures of two cell
 types in both 3D vertex and Voronoi models. We find that while the cell
 shape indices exhibit similar trends in both models, the registration
 between cell centers and cell orientation at the boundary are
 significantly different between the two models. We demonstrate that these
 macroscopic differences are caused by changes to the cusp-like restoring
 forces introduced by the different representations of the degrees of
 freedom at the boundary and that the Voronoi model is more strongly
 constrained by forces that are an artifact of the way the degrees of
 freedom are represented. This suggests that vertex models may be more
 appropriate for 3D simulations of tissues with heterotypic contacts.

title: Possible niche compression and individual specialization in Pacific Arctic beluga (Delphinapterus leucas) from the 19th to 20th century

description: Cetaceans have shown potential to be used as sentinel species for tracking
 environmental change in marine ecosystems, yet our assessment of change is
 typically limited to recent decades and lacks ecological baselines. Using
 historical museum specimens, we compared community niche metrics and
 degree of individual dietary specialization in groups of Pacific Arctic
 beluga (Delphinapterus leucas) from the 1800s (n = 5) to 1900s (n = 10)
 using stable carbon and nitrogen isotopes drilled from teeth. Beluga
 occupied a broader trophic niche and demonstrated a higher degree of
 individual specialization in the 1800s than in the 1900s. The cause of
 this shift is difficult to confirm given long timescales and constraints
 of specimen-based research but could indicate changes in the prey base or
 competition. The scale and nature of this detected shift provide
 perspective for continued research on these climate-vulnerable species.

title: Takeout gene expression is associated with temporal kin recognition

description: A key component of parental care is avoiding killing and eating your own
 offspring. Many organisms commit infanticide of young but switch to
 parental care at the time when their own offspring would be expected,
 known as temporal kin recognition. It is unclear why such indirect kin
 recognition is so common across taxa. One possibility is that conserved
 mechanisms that regulate timing and feeding in other contexts are co-opted
 to enable the evolution of temporal kin recognition. Here we determine
 whether takeout, a gene implicated in coordinating feeding, influences
 temporal kin recognition in the subsocial beetle the roundneck sexton
 beetle, Nicrophorus orbicollis. We find that takeout expression is not
 associated with non-parental feeding changes resulting from hunger, or in
 the general switch to the full parental care repertoire. However, beetles
 that accepted and provided care to their offspring had a higher takeout
 expression than beetles that committed infanticide. Together, these data
 support the idea that the evolution of temporal kin recognition may be
 enabled by co-option of mechanisms that integrate feeding behaviour in
 other contexts.
description: We conducted a large-scale experiment where we collected the
 heads of beetles of both sexes in parental and non-parental contexts to
 determine how <em>takeout</em> gene expression was associated
 with each context. Here, we experimentally tested for associations
 between <em>takeout</em> gene expression and hunger state, the
 development of parenting, and temporal kin recognition in the subsocial
 beetle <em>Nicrophorus orbicollis</em>. Raw
