title: Persistent firing and adaptation in optic-flow-sensitive descending neurons

description: A general principle of sensory systems is that they adapt to prolonged
 stimulation by reducing their response over time. Indeed, in many visual
 systems, including higher-order motion sensitive neurons in the fly optic
 lobes and the mammalian visual cortex, a reduction in neural activity
 following prolonged stimulation occurs. In contrast to this phenomenon,
 the response of the motor system controlling flight maneuvers persists
 following the offset of visual motion. It has been suggested that this gap
 is caused by a lingering calcium signal in the output synapses of fly
 optic lobe neurons. However, whether this directly affects the responses
 of the post-synaptic descending neurons, leading to the observed
 behavioral output, is not known. We use extracellular electrophysiology to
 record from optic-flow-sensitive descending neurons in response to
 prolonged wide-field stimulation. We find that, as opposed to most sensory
 and visual neurons, and in particular to the motion vision sensitive
 neurons in the brains of both flies and mammals, the descending neurons
 show little adaption during stimulus motion. In addition, we find that the
 optic-flow-sensitive descending neurons display persistent firing, or an
 after-effect, following the cessation of visual stimulation, consistent
 with the lingering calcium signal hypothesis. However, if the difference
 in after-effect is compensated for, subsequent presentation of stimuli in
 a test-adapt-test paradigm reveals adaptation to visual motion. Our
 results thus show a combination of adaptation and persistent firing in the
 neurons that project to the thoracic ganglia and thereby control
 behavioral output.

title: Genomic insights into adaptation to heterogeneous environments for the ancient relictual Circaeaster agrestis (Circaeasteraceae, Ranunculales)

description: Investigating the interaction between environmental heterogeneity and
 local adaptation is critical to understand the evoutionary history of a
 species, providing the premise for studying the response of organisms to
 rapid cimate change. However, for most species how exacty the spatial
 heterogeneity promotes popuation divergence and how genomic variations
 contribute to adaptive evolution remain poorly understood. We examine the
 contributions of geographica and environmental variables to population
 divergence of the relictual, alpine herb Circaeaster agrestis, as wel as
 genetic basis of local adaptation using RAD-seq and plastome data. We
 detected significant genetic structure with an extraordinary
 disequilibrium of genetic diversity among regions, and signals of
 isolation-by-distance along with isolation-by-resistance. The populations
 were estimated to begin diverging in the late Miocene, along with a
 possible ancestral distribution of the Hengduan Mountains and adjacent
 regions. Both environmental gradient and redundancy analyses revealed
 significant association between genetic variation and temperature
 variables. Genome‐environment association analyses identified 16
 putatively adaptive loci mainly related mainly to biotic and
 abiotic stress resistance. Our genome wide data provide new insights into
 the important roe of environmenta heterogeneity in shaping genetic
 structure, and access the footprints of ocal adaptation in an ancient
 reictual species, informing future conservation efforts.

title: Data from: Decadal changes in masting behaviour of oak trees with rising temperature

description: 1. Decadal changes in masting behaviour—directional changes in seed
 production with fluctuations on a decadal time scale—are attracting
 widespread attention in the context of global climate change. However, our
 mechanistic understanding of the effects of climate on seed production on
 a decadal scale is unsatisfactory, partly because of insufficient
 statistical analyses of long-term data on masting. 2. We detected decadal
 changes in masting behaviour in the Japanese oak (Quercus crispula) based
 on long-term data (38 years: 1980–2017) from the Kitakami Mountains of
 Japan. The moving average of seed production in a 20-year sliding window
 increased, whereas the coefficient of variation decreased. A wavelet power
 spectrum, as well as a second-order log-linear autoregressive (AR) model,
 showed that masting intervals shortened from 3 or 4 years to a 2-year
 cycle. 3. The moving average of seed production increased linearly as the
 moving average of temperature increased. Temporal variations of the two AR
 model coefficients as a function of temperature were well described by
 concave curves. 4. Synthesis. By conducting statistical analyses of a
 long-term seed-production dataset, we obtained significant evidence of
 decadal changes in the masting behaviour of the Japanese oak and showed
 that shortening of the masting interval was associated with rising
 temperature. A resource allocation shift and an environmental veto were
 discussed as possible mechanisms underlying the decadal change.

title: Rapid reversal of a potentially constraining genetic covariance between leaf and flower traits in Silene latifolia

description: Genetic covariance between two traits generates correlated responses to
 selection, and may either enhance or constrain adaptation. Silene
 latifolia exhibits potentially constraining genetic covariance between
 specific leaf area and flower number in males. Flower number is likely to
 increase via fecundity selection but the correlated increase in specific
 leaf area increases mortality, and specific leaf area is under selection
 to decrease in dry habitats. We selected on trait combinations in two
 selection lines for four generations to test whether genetic covariance
 could be reduced without significantly altering trait means. In one
 selection line, the genetic covariance changed sign and eigenstructure
 changed significantly, while in the other selection line eigenstructure
 remained similar to the control line. Changes in genetic
 variance-covariance structure are therefore possible without the
 introduction of new alleles, and the responses we observed suggest that
 founder effects and changes in frequency of alleles of major effect may be
 acting to produce the changes.

title: Data from: Introduced bees (Osmia cornifrons) collect pollen from both coevolved and novel host-plant species within their family-level phylogenetic preferences

description: Studying the pollen preferences of introduced bees allows us to
 investigate how species utilize host-plants when establishing in new
 environments. Osmia cornifrons is a solitary bee
 introduced into North America from East-Asia for pollination of crops in
 the Rosaceae. We investigated whether O. cornifrons 1)
 more frequently collected pollen from host-plant species they coevolved
 with from their geographic origin, or 2) prefer hosts-plant species of
 specific plant taxa independent of origin. To address this question, using
 pollen metabarcoding we examined the identity and relative abundance of
 pollen in larval provisions from nests located in different habitats with
 varying abundance of East-Asian and non-Asian plant species. Our results
 show that O. cornifrons disproportionately, yet not
 exclusively, collected pollen from their native range. Plants in the
 family Rosaceae were their most preferred pollen hosts, where they
 differentially collected species native to East-Asia, Europe, or North
 America depending on the landscape. Our results suggest that
 while O. cornifrons more frequently collect pollen of
 East-Asian origin, the collection of pollen from novel species within
 their phylogenetic familial affinities can facilitate pollinator
 establishment. This phylogenetic preference highlights the effectiveness
 of O. cornifrons as crop pollinators of a variety of
 Rosaceae crops from different geographic origins. Ourresults imply that
 globalization of non-native plant species may ease the naturalization of
 their coevolved pollinators outside of their native range.

title: Cyclic uniaxial mechanical stretching of cells using a LEGO® parts-based mechanical stretcher system

description: Mechanical cues are essential to the regulation of cell and tissue
 physiology. Henceforth, it has become an utmost necessity for cell
 biologists to account for those mechanical parameters when investigating
 biological processes and they need devices to manipulate cells
 accordingly. Here, we report a simple mechanical cell stretching system
 that can generate uniaxial cyclic mechanical stretch on cells in tissue
 culture. This system is based upon a low-cost battery-powered uniaxial
 cyclic mechanical stretcher exclusively built out of LEGO® parts combined
 to a stretchable PDMS tissue culture plate in order to grow and stretch
 cells. We characterize the system and show that it can be used with a wide
 variety of downstream applications including immunofluorescence, Western
 blotting and biochemical assays. We also illustrate how this system can be
 useful in a study as we investigated the behavior of integrin adhesion
 complexes upon cell stretching. We therefore present a cost-effective,
 multipurpose cell stretching system that should help understand mechanical
 signaling.

title: Heterospecific shorebird flocks increase safety and reduce intraspecific competition

description: Shorebirds join cohesive flocks for safety. The joining of individuals of
 several species in large heterospecific flocks can optimise individual
 vigilance and foraging. However, a large number of conspecific individuals
 in flocks may deplete food resources and increase intraspecific
 competition. In the present study, we argue that Nearctic-Neotropical
 migratory shorebird species join large heterospecific flocks in a balanced
 number as a way of controlling intraspecific competition. We recorded
 monospecific and heterospecific flocks in urban beaches from southeastern
 Brazil and annotated the species richness and the number of individuals
 per bird species per flock. Besides, we recorded the number of people
 around shorebird flocks to examine any relationship with flock size. We
 also recorded the foraging rate of the Semipalmated Plover
 (&lt;i&gt;Charadrius semipalmatus&lt;/i&gt;), a common
 migrant species in the region, as a species model to test competition and
 vigilance. We hypothesised that this species would exhibit a low foraging
 rate in scenarios with high intraspecific competition (i.e., large flocks
 with a high number of conspecifics) and high density of people, which may
 disturb birds. In the initial results, the density of people did not
 influence size of monospecific and heterospecific flocks; heterospecific
 flocks were larger than monospecific flocks, and heterospecific flocks
 increased in size by the addition of more species rather than more
 individuals of the same species. These data reflect a decrease in the
 relative abundance of individuals per species. Additionally, the
 Semipalmated Plover foraging rate was reduced in monospecific flocks,
 flocks with a high relative abundance (and total number) of the specific
 individuals and flocks surrounded by a high density of people. All these
 results indicate that shorebirds may adjust flock composition and size
 according to preferred foraging conditions, i.e., large and balanced
 heterospecific flocks with less intraspecific competition and less
 vigilance to potential predators in wintering areas.

title: Data from: Portable heaters for microhabitat heating experiments

description: 1. Global warming will likely cause more ecological change by altering how
 species interact with each other than by directly affecting individual
 species. Field heating experiments are essential to test how warming will
 change species interactions. However, such experiments pose many
 logistical challenges, including heater construction and accuracy and
 accessing necessary infrastructure. 2. To facilitate these experiments, we
 developed portable active heaters suitable for heating microhabitats and
 sites of species interactions. We validated heater performance using two
 different target microhabitats: rolled leaf refugia and aquatic
 microcosms. 3. Using plastic mesh, resistive heating wire, and an Arduino
 UNO microcontroller system with a custom shield, we built adjustable
 heaters that can dynamically heat small targets to at least 5°C above
 ambient temperature. Leaf target systems were heated with mean absolute
 errors (MAE) of 0.40‐1.06°C. Water target systems were heated with mean
 absolute errors of 0.02‐0.04°C. 4. These heaters can be customized to
 accurately heat a wide range of target sites (leaves, flowers, nests,
 small pools of water, etc.), many of which cannot be easily heated with
 traditional heaters. They can be easily constructed and require less field
 site infrastructure than many active heaters. These heaters’ adjustability
 and portability mean that they can help test the effects of global warming
 in many situations, particularly in remote and lightly developed areas.
description: The data were recorded automatically by the heater control system
 in 1-minute intervals in a text file. We removed the file header and
 converted it to a spreadsheet format. For details of how the heaters were
 constructed and deployed, please see the Methods in Ecology and Evolution
 paper.
description: These are pilot data for dynamic portable microhabitat heaters
 described in the associated Methods in Ecology and Evolution paper. In
 this test, rolled <em>Pleiostachya
 pruinosa</em> (Heliconiaceae) leaves were heated to 5°C above the
 ambient temperature. This heater system operated an ambient temperature
 sensor and four heaters (labeled A, B, C, and D) and recorded mean
 temperature and power usage every minute. All temperature data are in
 degrees Celsius. Power usage is expressed as a percentage of maximum
 power. In this case, "maximum power" is 44 W. There are no

title: Effects of Inspiratory Muscle Training Added to a Swimming Program in Children with Asthma

description: Background and Objectives: Asthma remains one of the most common chronic diseases in childhood, and despite advances in pharmacological management, its prevalence continues to rise globally. Physical activity, particularly swimming, has been proposed as a safe and beneficial form of exercise for asthmatic children due to the warm and humid environment that minimizes airway irritation. This study aimed to investigate the effects of adding inspiratory muscle training (IMT) to a structured swimming program on pulmonary function and asthma control in children with asthma. Materials and Methods: Thirty children with clinically diagnosed asthma, aged 8–11 years, were randomly assigned to either a swimming plus IMT group (n = 15) or a swimming-only control group (n = 15). Both groups participated in a 4-week supervised swimming program consisting of three 60-minute sessions per week. Inspiratory muscle training was integrated into the warm-up and cool-down phases for the experimental group. Pulmonary function parameters (FVC, FEV₁, FEV₁/FVC, PEF, MIP, MEP, MVV) and asthma control scores (Childhood Asthma Control Test [CACT]) were measured before and after the intervention. Statistical analyses were performed using repeated-measures ANOVA with significance set at p &lt; 0.001. Results: Following the 4-week intervention, significant improvements were observed in all respiratory parameters and asthma control indices in both groups (p &lt; 0.001). However, the swimming + IMT group showed substantially greater improvements in FEV₁ (↑46.4%), MIP (↑37.2%), MEP (↑42.6%), and CACT (↑69.5%) compared to the swimming-only group (FEV₁ ↑27.3%, MIP ↑10.3%, MEP ↑9.9%, CACT ↑30.1%). Effect sizes (Cohen’s d) were large across all primary outcomes, indicating a strong clinical impact of the combined intervention. Conclusions: The addition of inspiratory muscle training to a structured swimming program markedly enhances respiratory muscle strength, pulmonary function, and asthma control in children with mild-to-moderate asthma. These findings support incorporating IMT into aquatic exercise-based rehabilitation programs for pediatric asthma management.
