title: Development and field evaluation of a motion sensor activated suction trap to study vector-host interactions

description: 1. Researchers elucidating vectors of zoonotic diseases encounter problems
 with inefficient surveillance techniques leading to underestimation of the
 importance of some species, and the overestimation of the importance of
 others. Carbon dioxide-baited light traps are the most widely used traps
 for sampling vector groups. However aspirating directly from the hosts is
 the most accurate method to incriminate vectors. 2. A novel vector
 trapping system was developed, consisting of a suction trap, activated by
 a motion sensor, and controlled by a microcontroller, which activates
 automatically when host animals approach. The prototype was tested in two
 field experiments with ungulates and biting midges (Diptera:
 Ceratopogonidae) at a preserve in Florida. We measured the biting midge
 community collected at traps near and far from hosts and compared
 communities using diversity metrics and abundance curves. 3. Traps
 activated in the presence of host animals with 94% accuracy. Diversity and
 richness of Culicoides species differed between sensor
 and control traps with 11 species captured by control traps and 7 species
 by sensor traps. Vector species were captured in significantly greater
 numbers in sensor traps, while more non-vector species were caught in
 control traps. 4. Results confirm that vector species can be
 underrepresented in light trap collections, likely due to their tight
 associations with vertebrate hosts, a finding that should be taken into
 consideration when incriminating arbovirus vectors. Our novel trap system
 was a first attempt at solving the issue of collecting vector species from
 non-tame animals, effectively aspirating questing midges. Simple
 modifications of the system could be made to target other vector-host
 systems.

title: Ant foraging strategies vary along a natural resource gradient

description: Food selection by foragers is sensitive to the availability of resources,
 which may vary along geographical gradients. Hence, selectivity of food
 types by foragers is expected to track these resource gradients. Here we
 addressed this hypothesis and asked if foraging decisions of seed-eating
 ants differ along a geographic gradient of habitat productivity. The study
 was carried out for two years at five sites along a natural climatic
 gradient, ranging from arid to Mediterranean, where plant productivity
 varies 6-fold across a short geographic distance of 250 km. We found that
 in ant colonies of the genus Messor, collective foraging decisions
 differed along the gradient. Specifically, at the high-productivity sites,
 a stronger association was found between plant seed availability and
 selectivity, suggesting that colonies respond more accurately to
 within-patch variation in food amounts. In contrast, colonies in
 low-productivity sites foraged in patches with higher concentration of
 seeds, suggesting that they respond more accurately to among-patch
 variation in food amounts. Moreover, at the high-productivity sites,
 colonies were more discriminating in their choice of food and preferred
 bigger seeds, while in the low-productivity sites, where smaller seeds
 were relatively more abundant, food collection depended mostly on seed
 availability. An experiment with artificial seed patches performed along
 the same climatic gradient, revealed no difference in food selectivity
 across sites when food type and availability were similar, and a general
 preference for bigger over medium-sized seeds. Overall, our findings
 suggest that resource availability is an important factor explaining food
 choice along a climatic gradient and imply that in low-productivity
 regions small-seeded species incur high predation pressure, whereas in
 high-productivity regions, large-seeded species suffer higher predation.
 This could have important consequences for plant species composition,
 particularly at the face of climate change, which could dramatically alter
 the foraging decisions of granivores.

title: Data from: The context dependent effects of host competence, competition, and the pathogen transmission mode on disease prevalence

description: Biodiversity in communities is changing globally, including the gain and
 loss of host species in host-pathogen communities. Increased host
 diversity can cause infection prevalence in a focal host to increase
 (amplification) or decrease (dilution).  However, it is unclear
 what general rules govern the context dependent effects, in part because
 theories for pathogens with different transmission modes have developed
 largely independently.  Using a two-host model, we explore how
 the pathogen transmission mode and characteristics of a second host
 (disease competence and competitive ability) influence disease prevalence
 in a focal host.  Our work shows how the theories for pathogens
 with environmental transmission, density-dependent direct transmission,
 and frequency-dependent direct transmission can be unified.  Our
 work also identifies general rules about how host and pathogen
 characteristics affect amplification/dilution.  For example,
 higher competence hosts promote amplification, unless they are strong
 interspecific competitors; strong interspecific competitors promote
 dilution, unless they are large sources of new infections; and dilution
 occurs under frequency-dependent direct transmission more than
 density-dependent direct transmission, unless interspecific host
 competition is sufficiently strong.  Our work helps explain how
 the characteristics of the pathogen and a second host affect disease
 prevalence in a focal host.

title: Model code for reconstructing biomass burning emissions from ice core records of acetylene, ethane, and methane

description: Biomass burning emissions of trace gases are inferred from ice
 core levels of acetylene, ethane, methane and its stable isotopes over the
 last 1,000 years (Nicewonger et al., 2018, 2020). In Nicewonger et al.
 2020 JGR-A, we attempt to reconcile the individual biomass burning records
 from each trace gas into a single fire history of dry matter burned over
 the last 1,000 years. We find that temporal trends in fire
 inferred from the three trace gas records are in reasonable agreement for
 the past millennium. However, the trace gas records do not yield a
 quantitatively consistent fire history even when assuming dramatic changes
 to the spatial location of fires and to the type of biomes through time.
 This dataset includes the MATLAB scripts used to calculate biomass burning
 emission histories for each of the gases: acetylene, ethane, and methane.
 An Excel file included has the ice core methane and 13CH4 values used in
 this study. Please refer to the original manuscripts and datafiles located

title: Anti-seizure medication use during pregnancy and risk of ASD and ADHD in children

description: Objective: To determine whether children born to women who use
 anti-seizure medications (ASMs) during pregnancy have higher risk of
 autism spectrum disorder (ASD) and attention-deficit/hyperactivity
 disorder (ADHD) independent of confounding factors. Methods: We used
 Swedish-register data (n=14,614 children born 1996-2011 and followed
 through 2013) to examine associations in children of women with epilepsy,
 using the largest sample to date and adjusting for a range of measured
 confounders. We examined maternal-reported first-trimester use of any ASM
 (22.7%); and the three most commonly reported individual drugs (valproic
 acid, 4.8%; lamotrigine, 6.8%; and carbamazepine, 9.7%). We identified ASD
 with ICD-10 diagnoses and ADHD with ICD-10 diagnoses or filled
 prescriptions of ADHD medication. Results: Examination of individual drugs
 revealed that after adjustment for confounding, use of valproic acid was
 associated with ASD (Hazard Ratio=2.30, 95%CI=1.53-3.47) and ADHD
 (HR=1.74, 95%CI=1.28-2.38). Whereas a small, non-statistically significant
 association with ASD (HR=1.25, 95%CI=0.88-1.79) and ADHD (HR=1.18,
 95%CI=0.91-1.52) remained for reported use of carbamazepine, confounding
 explained all of the associations with lamotrigine (HRASD=0.86,
 95%CI=0.67-1.53; HRADHD=1.01, 95%CI=0.67-1.53). Conclusions: We found no
 evidence of risk related to exposure to lamotrigine, whereas we observed
 elevated risk of ASD and ADHD related to maternal use of valproic acid.
 Associations with carbamazepine were weak and not statistically
 significant. Our findings add to a growing body of evidence that suggest
 that certain ASMs may be safer than others in pregnancy.

title: Use of social media in the marketing of agricultural products and farmers’ turnover in South-South Nigeria

description: The study investigated the use of social media in the marketing of
 agricultural products and farmers turnover in South-South Nigeria. The
 purpose of the study was to determine the extent to which the usage of
 social media in the marketing of agricultural products in Nigeria can
 enhance efficiency and farmers’ sales turnover. It employed the survey
 research design and data were collected with the help of a structured
 questionnaire. Research data were analysed using t-test and least square
 method. The results showed that the use of social media (Facebook,
 WhatsApp and Instagram) in the marketing of agricultural products enhances
 efficiency and turnover of farmers through a significant reduction in the
 cost of marketing agricultural products as well as increased awareness and
 the attendant increase in demand for agricultural produce.
description: The study employed the quantitative research method.
 Specifically, the conclusive research design consistent with Inegbedion
 (2018), Inegbedion, Obadiaru, Obasaju, Asaleye and Lawal (2019) and
 Inegbedion, Obadiatu and Bello (2016) while the survey method was used in
 data collection. <i>Participants
 </i> The population of the study
 consisted of four thousand, Two hundred and eighty (4280) farmers
 registered in cooperative societies. Of this number, 1620 are from Edo
 State, 1460 are from Ondo State while 1200 are from Delta state. Taro
 Yamane formula was used to estimate a sample size of 366 and proportional
 allocation was used to assign 139, 125 and 102 to Edo, Ondo and Delta
 States respectively. Of the 366 respondents that were sampled, 246,
 representing 67.2% of them voluntarily participated in the study. The
 participants were randomly selected from farmers` cooperative societies in
 the three states. The choice of these states was informed mainly by
 convenience. Specifically, samples were taken from the current members of
 the cooperative societies. The sample consisted of crop, poultry and fish
 farmers who belong to cooperative societies in the states with evidence of
 usage of social media (Facebook, WhatsApp or Instagram), among others. The
 sampling frame was requested from the management of the cooperative
 societies. <i>Materials</i> Based on the sampling frame, a sample of respondents was selected. Thereafter, the sampled respondents were requested to participate in the study through the social media. A survey was constructed and used to examine use of social media in agricultural marketing and its implication for efficiency and sales turnover through the administration of a questionnaire, which served as the research instrument. The questionnaire contained bio-data questions and 5-point Likert scale questions dealing with social media usage in agricultural marketing and its implication for efficiency and sales turnover in south west Nigeria. Information was elicited from the respondents via structured questionnaires through the social media channels (Facebook, instagram and WhatsApp).

title: Raw images of targeted gearshifting in actin-based active nematic liquid crystals

description: Active materials are capable of converting free energy into mechanical
 work to produce autonomous motion, and exhibit striking collective
 dynamics that biology relies on for essential functions. Controlling those
 dynamics and transport in synthetic systems has been particularly
 challenging. Here, we introduce the concept of spatially structured
 activity as a means to control and manipulate transport in active nematic
 liquid crystals consisting of actin filaments and light-sensitive myosin
 motors. Simulations and experiments are used to demonstrate that
 topological defects can be generated at will, and then constrained to move
 along specified trajectories, by inducing local stresses in an otherwise
 passive material. These results provide a foundation for design of
 autonomous and reconfigurable microfluidic systems where transport is
 controlled by modulating activity with light.
description: These data are images of a two dimensional nematic liquid crystal
 formed by crowding short, labelled actin filaments onto an oil-water
 interface using methylcellulose as the crowding agent. Images from an
 upright nikon microscope with a spinning disk confocal head. The laser
 used to excite the fluorophore is polarized such that labelled
 actin filaments that point in the y direction in the laboratory frame
 fluoresce more than those with an orthogonal orientation. 
description:  These liquid crystals are driven out of equilibrium by custom
 Myosin motors. These motors, when stimulated with ~470nm light, can
 undergo a conformational change that results in a higher gliding speed
 along the filament.  In these experiments this stimulation wavelength is
 targeted to just one region of the sample using a digital micromirror
 array. "Figure_1_ROI.roi" is the stimulation region for the data
 labelled "Figure_1_raw.tiff" and
 likewise "Stimulation_ROI_F5.rgn" is the stimulated region for
 the data of the format "Figure_5_xx.tiff". 
   In the data from figure 1, one pixel
 is 0.1083 microns. In the data from figure 5, one pixel is 0.1625

title: Origins of 1/f-like tissue oxygenation fluctuations in the murine cortex

description: The concentration of oxygen in the brain spontaneously fluctuates, and the
 distribution of power in these fluctuations has a 1/f-like spectra, where
 the power present at low frequencies of the power spectrum is orders of
 magnitude higher than at higher frequencies. Though these oscillations
 have been interpreted as being driven by neural activity, the origins of
 these 1/f-like oscillations is not well understood. Here, to gain insight
 of the origin of the 1/f-like oxygen fluctuations, we investigated the
 dynamics of tissue oxygenation and neural activity in awake behaving mice.
 We found that oxygen signal recorded from the cortex of mice had 1/f-like
 spectra. However, band-limited power in the local field potential, did not
 show corresponding 1/f-like fluctuations. When local neural activity was
 suppressed, the 1/f-like fluctuations in oxygen concentration persisted.
 Two-photon measurements of erythrocyte spacing fluctuations and
 mathematical modelling show that stochastic fluctuations in erythrocyte
 flow could underlie 1/f-like dynamics in oxygenation. These results
 suggest that the discrete nature of erythrocytes and their irregular flow,
 rather than fluctuations in neural activity, could drive 1/f-like
 fluctuations in tissue oxygenation.

title: Utilizing next-generation sequencing to identify prey DNA in western North Atlantic grey seal (Halichoerus grypus) diet

description: Increasing grey seal (Halichoerus grypus) abundance in coastal New England
 is leading to social, political, economic, and ecological controversies.
 We studied grey seal feeding habits through next-generation sequencing of
 prey DNA using 16S amplicons from seal scat (N = 74) collected from a
 breeding colony on Monomoy Island in Massachusetts, U.S. and report
 frequency of occurrence and relative read abundance. We also assigned seal
 sex to scat samples using a revised PCR assay. In contrast to current
 understanding of grey seal diet from hard parts and fatty acid analysis,
 we found no significant difference between male and female diet measured
 by alpha and beta diversity. Overall, we detected 24 prey groups, 18 of
 which resolved to species. Sand lance (Ammodytes spp.) was the most
 frequently consumed prey group, with a frequency of occurrence (FO) of
 97.3%, consistent with previous studies, but Atlantic menhaden (Brevoortia
 tyrannus), the second most frequently consumed species (FO = 60.8%), has
 not been documented in U.S. grey seal diet previously. Our results suggest
 that a metabarcoding approach to seal food habits can yield important new
 ecological insights, but that traditional hard parts analysis does not
 underestimate consumption of Atlantic cod (Gadus morhua; FO = 6.7% Gadidae
 spp.) and salmon (Salmo salar; FO = 0%), two particularly valuable species
 of concern.

title: Combined effects of rearing and testing temperatures on sperm traits

description: Temperature experienced during early development can affect a range of
 adult life history traits. Animals often show seemingly adaptive
 developmental plasticity – with animals reared at
 certain temperatures performing better as adults at those
 temperatures. The extent to which this type of adaptive response
 occurs in gonadal tissue that affect sperm traits is, however, poorly
 studied. We initially reared male mosquitofish (Gambusia
 holbrooki) at either 18oC or 30oC, and then measured their sperm
 reserves as adults. We also looked at the velocity of their sperm, at both
 the matched and mismatched temperature. Although males reared at
 30oC were larger than those initially reared at 18oC, there was
 no detectable effect of rearing temperature on absolute sperm number.
 Sperm swam faster at 30oC than 18oC regardless of the male’s
 rearing temperature. Therefore, we found no evidence of adaptive
 developmental plasticity. Rearing temperature did, however,
 significantly influence the relationship between male body size
 and sperm velocity. Larger males had faster sperm when reared at
 the warmer temperature, and slower sperm when reared at the
 cooler temperature. This suggests that rearing temperature could
 alter the relationship between pre- and post-copulatory sexual
 selection as male size affects mating success. Finally, there was a
 positive correlation between velocity at the two test
 temperatures, suggesting that temperature experienced during
 sperm competition is unlikely to affect a male’s relative fertilisation
 success.
