title: An elevational gradient in floral traits and pollinator assemblages in the Neotropical species Costus guanaiensis var. Tarmicus in Peru

description: Different populations of plant species can adapt to their local
 pollinators and diverge in floral traits accordingly. Floral
 traits are subject to pollinator-driven natural
 selection to enhance plant reproductive success. Studies on
 temperate plant systems have shown
 pollinator-driven selection results in floral trait variation
 along elevational gradients, but studies in tropical systems are
 lacking. We analyzed floral traits and pollinator assemblages in
 the Neotropical bee-pollinated taxon Costus guanaiensis
 var. tarmicus across four sites along a steep elevational
 gradient in Peru. We found variations in floral traits of size,
 color, and reward, and in the pollinator assemblage along the
 elevational gradient. We examined our results considering two hypotheses,
 (1) local adaptation to different bee assemblages, and (2) the
 early stages of an evolutionary shift to a new pollinator
 functional group (hummingbirds). We found some evidence consistent with
 the adaptation of C. guanaiensis var. tarmicus to the local
 bee fauna along the studied elevational gradient. Corolla width
 across sites was associated with bee thorax width of the local
 most frequent pollinator. However, we could not rule out the
 possibility of the beginning of a bee-to-hummingbird pollination
 shift in the highest-studied site. Our study is one of
 the few geographic-scale analyses of floral trait and
 pollinator assemblage variation in tropical plant species. Our
 results broaden our understanding of
 plant-pollinator interactions beyond temperate
 systems by showing substantial intraspecific divergence in both
 floral traits and pollinator assemblages across geographic space
 in a tropical plant species.

title: Turbulent flux measurements of the near-surface and residual-layer small particle events

description: According to recent field studies, almost half of the New Particle
 Formation (NPF) events occur aloft, in a residual layer, near the top of
 the boundary layer. Therefore, measurements of the meteorological
 parameters, precursor gas concentrations, and aerosol loadings conducted
 at the ground level are often not representative of the conditions where
 the NPFs take place. This paper presents new measurements obtained during
 the Turbulent Flux Measurements of the Residual Layer Nucleation
 Particles, conducted at the Southern Great Plains research site. Vertical
 turbulent fluxes of 3–10 nm-sized particles were measured using a sonic
 anemometer and two condensation particle counters with nominal cutoff
 diameters of 3 nm and10 nm mounted at the top of the 10-m telescoping
 tower. Aerosol number size distribution (5 to 300 nm) was determined
 through the ground-based Scanning Mobility Particle Sizers. The size
 selected (15 to 50 nm) particle hygroscopicity was derived with the
 Humidified Tandem Differential Mobility Analyzer. The ground-level
 observations were supplemented by vertically-resolved measurements of
 horizontal and vertical wind speed and aerosol backscatter. The data
 analysis suggests that 1) turbulent flux measurements of 3-10 nm particles
 can distinguish between near-surface and residual-layer small particle
 events; 2) sub-50 nm particles had a hygroscopicity value of 0.2,
 suggesting that organic compounds dominate atmospheric nanoparticle
 chemical composition at the site; and 3) current methodologies are
 inadequate for estimating dry deposition velocity of sub-10 nm particles
 because it is not feasible to measure particle concentration very near the
 surface, in the diffusion sublayer.

title: Color, activity period, and eye structure in four lineages of ants: Pale, nocturnal species have evolved larger eyes and larger facets than their dark, diurnal congeners

description: The eyes of insects display an incredible diversity of adaptations to
 enhance vision across the gamut of light levels they experience. One
 commonly studied contrast is the difference in eye structure between
 nocturnal and diurnal species, with nocturnal species typically having
 features that enhance eye sensitivity such as larger eyes, larger eye
 facets, and larger ocelli. In this study, we compared eye structure
 between workers of closely related nocturnal and diurnal above-ground
 foraging ant species (Hymenoptera: Formicidae) in four genera
 (Myrmecocystus, Aphaenogaster, Temnothorax, Veromessor). In all four
 genera, nocturnal species tend to have little cuticular pigment (pale),
 while diurnal species are heavily pigmented (dark), hence we could use
 cuticle coloration as a surrogate for activity pattern. Across three
 genera (Myrmecocystus, Aphaenogaster, Temnothorax), pale species, as
 expected for nocturnally active animals, had larger eyes, larger facet
 diameters, and larger visual spans compared to their dark, more day-active
 congeners. This same pattern occurred for one pale species of Veromessor,
 but not the other. There were no consistent differences between nocturnal
 and diurnal species in interommatidial angles and eye parameters both
 within and among genera. Hence, the evolution of eye features that enhance
 sensitivity in low light levels do not appear to have consistent
 correlated effects on features related to visual acuity. A survey across
 several additional ant genera found numerous other pale species with
 enlarged eyes, suggesting these traits evolved multiple times within and
 across genera. We also compared the size of the anterior ocellus in
 workers of pale versus dark species of Myrmecocystus. In species with
 larger workers, the anterior ocellus was smaller in pale than in dark
 species, but this difference mostly disappeared for species with smaller
 workers. Presence of the anterior ocellus also was size-dependent in the
 two largest pale species.

title: Weapon performance and contest assessment strategies of the cavitating snaps in snapping shrimp

description: Animals compete in contests over limited resources. Contestants forfeit
 once they ascertain that their opponent has greater resource holding
 potential (RHP) (mutual assessment) or once they reach a threshold of
 costs (self assessment). Functional scaling studies of contest behavior
 performance can inform how assessment signals, offensive capacity, and
 endurance scale with RHP and thereby elucidate the mechanisms through
 which each of these assessment types operate. Here, we performed
 behavioral contest analyses to determine the assessment strategies used in
 snapping shrimp (Alpheus heterochaelis) contests. Then, we used
 biomechanical measurements of a common contest behavior to inform how
 assessment might operate. We were specifically interested in the snapping
 behavior during which snapping shrimp fire imploding cavitation bubbles –
 hereafter, “snaps” – at their opponents. We showed
 that A. heterochaelis use mutual assessment early in
 contests.  Then, when they fire snaps, they switch to
 cumulative assessment – a type of self assessment where
 contestants endure costs from their own behaviors (e.g. energy) and their
 opponent’s (e.g. injury). Because larger individuals tend to win
 contests, we then tested how the maximum performance and endurance of
 snaps scaled with size. We measured the average angular velocity of the
 snapping dactyl, cavitation bubble duration, and pressure of snaps as
 metrics of performance. We measured 10 snaps per individual (n = 76
 individuals). From this series of 10 snaps, we calculated the maximum of
 each metric as the maximum performance and the attrition of each metric
 over the course of ten snaps as a measure of endurance. Maximum
 performance increased with size, but endurance did not. This
 suggests that cumulative assessment in snapping shrimp is driven by
 opponent-imposed costs. Our results are not consistent with
 self-assessment based on endurance; however, the experiment could not
 fully replicate the quick succession of snaps fired in real contests.
 Future experiments should better replicate the rapid firing of snaps to
 test if endurance matters in a more ecologically relevant
 context. Our framework of integrating biomechanics and behavioral
 ecology provide a pathway to identify precise mechanisms of contest
 assessment and animal behavior more broadly.

title: Rocky Mountain Brook Trout harvest project genotypes

description: Sustainable management of exploited populations benefits from integrating
 demographic and genetic considerations into assessments, as both play a
 role in determining harvest yields and population persistence. This is
 especially important in populations subject to size-selective harvest,
 because size selective harvesting has the potential to result in
 significant demographic, life-history, and genetic changes. We
 investigated harvest-induced changes in the effective number of breeders (
 ) for introduced brook trout populations (Salvelinus fontinalis) in alpine
 lakes from western Canada. Three populations were subject to three years
 of size-selective harvesting, while three control populations experienced
 no harvest. The  decreased consistently across all harvested
 populations (on average 60.8%) but fluctuated in control populations.
 There were no consistent changes in  between control or harvest
 populations, but one harvest population experienced a decrease in
  of 63.2%. The /  ratio increased consistently across
 harvest lakes; however we found no evidence of genetic compensation (where
 variance in reproductive success decreases at lower abundance) based on
 changes in family evenness ( ) and the number of full-sibling families (
 ). We found no relationship between  and  or between /
  and  . We posit that change in  was buffered
 by constraints on breeding habitat prior to harvest, such that the same
 number of breeding sites were occupied before and after harvest. These
 results suggest that effective size in harvested populations may be
 resilient to considerable changes in Nc in the short-term, but it is still
 important to monitor exploited populations to assess the risk of
 inbreeding and ensure their long-term survival.
description: These data were produced from young-of-the-year brook trout
 samples, collected from lakes in the Canadian Rocky Mountains. These lakes
 were either subject to size-selective harvest at a rate of ~0.59, or were
 left as controls (no harvest). Young-of-the-year brook trout were sampled
 via electrofishing, a fin clip was collected, and they were released. DNA
 from the tissues was extracted using a modified Chelex protocol, was
 amplified, and then sequenced using an Illumina Miseq Sequencer. The
 genotypes were then demultiplexed and manually scored using MEGASAT
 software. See Clarke et al. (2022) for further details on the molecular
 protocol and experimental design.

title: Data from: Artificial light at night may decrease predation risk for terrestrial insects

description: Artificial light at night (ALAN) is thought to be detrimental for
 terrestrial insect populations. Whilst there exists evidence for lower
 abundance under ALAN, underlying mechanisms remain unclear. One mechanism
 by which ALAN may contribute to insect declines may be through
 facilitating increased predation. We investigated this by experimentally
 manipulating insect-substitute abundance under differential levels of
 light. We used insect-containing birdfeed placed at varying distances from
 streetlights as a proxy for terrestrial insects, inspecting the rate of
 predation before and after dusk (when streetlights are respectively off
 and on). We found that there was a significantly greater effect of
 increasing distance on predation after dusk, suggesting that predation was
 actually reduced by greater levels of artificial light. This may occur
 because ALAN also increases the vulnerability of insectivores to their own
 predators. Implications for foraging behaviour and alternative
 explanations are discussed.

title: Data for: Activation of bisulfite by LaFeO3 loaded on red mud for degradation of organic dye

description: In this study, red mud was used as a support for LaFeO3 to prepare a
 synergistic catalyst (LaFeO3-RM) via ultrasonic-assisted sol-gel method
 for the enhanced removal of methylene blue (MB) assisted with bisulfite
 (BS) in an aqueous solution. The Characterization of SEM and BET indicated
 that comparing with the non-porous structure of bulk LaFeO3, LaFeO3-RM
 exhibited high surface area and obvious porous structure with a higher
 pore volume (i.e. 10 times). XRD, XPS and FTIR revealed that in addition
 to dispersing LaFeO3 particles, the support of porous RM also increased Fe
 oxidation activity, oxygen-containing functional groups and chemically
 adsorbed oxygen (from 44.3% to 90.3%) of LaFeO3-RM which enhanced the
 catalytic performance in structure and chemical composition. MB was
 removed through the synergistic effect of adsorption and catalysis with MB
 molecule was first absorbed on the surface and then degraded. The
 pseudo-first-order kinetic constant of LaFeO3-RM was 6 times than that of
 LaFeO3. Fe(III) in LaFeO3-RM played a key role in the activation of BS to
 produce SO4·- by the redox cycle of Fe(III)/Fe(II). With the application
 of LaFeO3-RM as a promising low-cost synergistic catalyst for the
 activation of BS under neutral condition, this work provides a new
 approach of using porous industrial waste to improve the catalytic
 performance of LaFeO3.

title: Data for: Five decades of data yield no support for adaptive biasing of offspring sex ratio in wild baboons (Papio cynocephalus)

description: Over the past 50 years, a wealth of testable, often conflicting,
 hypotheses has been generated about the evolution of offspring sex ratio
 manipulation by mothers. Several of these hypotheses have received support
 in studies of invertebrates and some vertebrate taxa. However, their
 success in explaining sex ratios in mammalian taxa, and especially in
 primates, has been mixed. Here, we assess the predictions of four
 different hypotheses about the evolution of biased offspring sex ratios in
 the well-studied baboons of the Amboseli basin in Kenya: the
 Trivers-Willard, female rank enhancement, local resource competition, and
 local resource enhancement hypotheses. Using the largest sample size ever
 analyzed in a primate population (n = 1372 offspring), we test the
 predictions of each hypothesis. Overall, we find no support for adaptive
 biasing of sex ratios. Offspring sex is not consistently related to
 maternal dominance rank or biased towards the dispersing sex, nor it is
 predicted by group size, population growth rates, or their interaction
 with maternal rank. Because our sample size confers power to detect even
 subtle biases in sex ratio, including modulation by environmental
 heterogeneity, these results suggest that adaptive biasing of offspring
 sex does not occur in this population.

title: Data from: Behavior shapes retinal motion statistics during natural locomotion

description: Walking through an environment generates retinal motion, which humans rely
 on to perform a variety of visual tasks. Retinal motion patterns are
 determined by an interconnected set of factors, including gaze location,
 gaze stabilization, the structure of the environment, and the walker’s
 goals. The characteristics of these motion signals have important
 consequences for neural organization and behavior. However, to date, there
 are no empirical in situ measurements of how combined eye and body
 movements interact with real 3D environments to shape the statistics of
 retinal motion signals. Here, we collect measurements of the eyes, the
 body, and the 3D environment during locomotion. We describe properties of
 the resulting retinal motion patterns. We explain how these patterns are
 shaped by gaze location in the world, as well as by behavior, and how they
 may provide a template for the way motion sensitivity and receptive field
 properties vary across the visual field.

title: Effects of a body manipulation of Japanese martial arts on interpersonal correlation of postural sway

description: This study aimed to investigate the nature of a specific body manipulation
 named Suichoku-Ririku (SR) in Japanese martial arts. SR is regarded as a
 method to change the way of stance and to distort the balance control of
 the opponent, but its nature and mechanism are unknown. In the present
 study, we attempted to determine the effect of SR in the cases where a
 person stood alone (Expt. 1) and where two persons stood in contact (Expt.
 2). We compared several centers of pressure (COP) measures between the
 normal stance and SR stance conditions. When participants stood
 independently (Expt. 1), the COP path length, the standard deviation of
 COP velocity, and permutation entropy of the COP increased with the SR
 stance, which suggested that the SR maneuver destabilized a quiet stance.
 When two participants stood (with normal stance) in contact by
 wrist-holding or by light touch (Expt. 2), their COP motions were
 correlated with each other, as previously reported. When one of the
 participants took the SR maneuver, their correlation and mutual
 information were maintained, denying the view that SR would diminish the
 interpersonal correlation of body sway. On the other hand, a fluctuation
 in the COP increased only for the participant taking the SR maneuver, and
 not for the other participant. This asymmetric effect of the SR maneuver
 between two participants, irrespective of maintained mutual correlation,
 suggests that the relationship between the balance controls of two
 participants was partly disrupted. We discuss possible mechanisms for the
 present results.
