title: Effect of stressors on the carrying capacity of spatially distributed metapopulations

description: Stressors such as antibiotics, herbicides and pollutants are becoming
 increasingly common in the environment. The effects of stressors on
 populations are typically studied in homogeneous, non-spatial settings.
 However, most populations in nature are spatially distributed over
 environmentally heterogeneous landscapes with spatially-restricted
 dispersal. Little is known about the effects of stressors in these more
 realistic settings. Here, we combine laboratory experiments with novel
 mathematical theory to rigorously investigate how a stressor’s
 physiological effect and spatial distribution interact with dispersal to
 influence population dynamics. We prove mathematically that if a stressor
 increases death rate and/or simultaneously decreases population growth
 rate and yield, a homogeneous distribution of stressor leads to a lower
 total population size than if the same amount of stressor was
 heterogeneously distributed. We experimentally test this prediction on
 spatially-distributed populations of budding yeast, Saccharomyces
 cerevisiae . We find that the antibiotic, cycloheximide, increases yeast
 death rate but reduces growth rate and yield. Consistent with our
 mathematical predictions, we observe that a homogeneous spatial
 distribution of cycloheximide minimizes the total equilibrium size of
 experimental metapopulations, with the magnitude of the effect depending
 predictably on dispersal rate and geographic pattern of antibiotic
 heterogeneity. Our study has implications for assessing population risk
 posed by pollutants, antibiotics, and global change, and in the rational
 design of strategies for employing toxins to control pathogens and pests.
description: The data were collected with budding yeast. We measured
 population density using a microplate photometer (Tecan Infinite M200 Pro)
 to obtain the optical density at 660 nm (OD660) of each well.
 Simulations were performed in Matlab R2018b.

title: New application of strontium isotopes reveals evidence of limited migratory behaviour in Late Cretaceous hadrosaurs

description: Dinosaur migration patterns are very difficult to determine, often relying
 solely on the geographic distribution of fossils.  Unfortunately,
 it is generally not possible to determine if a fossil taxon’s geographic
 distribution is the result of migration or simply a wide
 distribution.  Whereas some attempts have been made to use
 isotopic systems to determine migratory patterns in dinosaurs, these
 methods have yet to achieve wider usage in the study of dinosaur ecology.
 Here we have used strontium isotope ratios from fossil enamel to
 reconstruct the movements of an individual hadrosaur from Dinosaur
 Provincial Park in Alberta, Canada.  Results from this study are
 consistent with a range or migratory pattern between Dinosaur Provincial
 Park and a contemporaneous locality in the South Saskatchewan River area,
 Alberta Canada.  This represents a minimum distance of
 approximately 80 km, which is consistent with migrations seen in modern
 elephants. These results suggest the continent-wide distribution of some
 hadrosaur species in the Late Cretaceous of North America is not the
 result of extremely long-range migratory behaviours.
description: Data was obtained from manually collected powders derived from
 fossil materials.  All samples were measured using Thermal Ionization Mass
 Spectrometry (TIMS).  No corrections have been applied to the data, nor
 has it been transformed.  See manuscript supplimentary for
 details.

title: The cost effectiveness of surgery for drug resistant temporal lobe epilepsy in the US

description: Objective: Surgery is an effective but costly treatment for many patients
 with drug resistant temporal lobe epilepsy (DR-TLE). We aim to evaluate
 whether, in the United States, 1) surgery is cost-effective compared to
 medical management for patients deemed surgical candidates, 2) surgical
 evaluation is cost-effective for DR-TLE patients in general. Methods: We
 use a semi-Markov model to assess the cost-effectiveness of surgery and
 surgical evaluation over a lifetime horizon. We use 2nd order Monte Carlo
 simulations to conduct probabilistic sensitivity analyses to estimate
 variation in model output. We adopt both healthcare and societal
 perspectives, including direct healthcare costs (e.g. surgery, AEDs) and
 indirect costs (e.g. lost earnings by patients and care providers.) We
 compare incremental cost-effectiveness ratio (ICER) to societal
 willingness-to-pay (~$100,000 per Quality Adjusted Life Year) to determine
 whether surgery is cost-effective. Results: Epilepsy surgery is cost
 effective compared to medical management in surgically eligible patients
 by virtue of being cost saving ($328K vs. 423K) and more effective (16.6
 QALY vs. 13.6 QALY) than medical management in the long run. Surgical
 evaluation is cost-effective in DR-TLE patients even if the probability of
 being deemed a surgical candidate is only 5%. From a societal perspective,
 surgery becomes cost effective within 3 years and 89% of simulations favor
 surgery over the lifetime horizon. Conclusion: For surgically eligible
 DR-TLE patients, surgery is cost-effective. For DR-TLE patients in
 general, referral for surgical evaluation (and possible subsequent
 surgery) is cost-effective. DR-TLE patients should be referred for
 surgical evaluation without hesitation on cost-effectiveness grounds.

title: Data from: The perception of caricatured emotion in voice

description: Data for Whiting et al. (2020, Cognition): "The perception of
 caricatured emotion in voice". Raw behavioural data and
 sound stimuli.
description: Participants
 performed three behavioural tasks across three subsequent different-day
 sessions: paired dissimilarity ratings (sessions 1 and 2), followed
 by emotion ratings, arousal/valence ratings, and speeded emotion
 categorisation (session 3). In the dissimilarity ratings task,
 participants rated the perceived similarity of all (within-speaker) pairs
 of stimuli in the absence of instructions about any particular stimulus
 feature that would drive their ratings. On each of two sessions,
 participants rated the similarity between all stimuli from a given speaker
 (speaker order counterbalanced across participants). On each trial, they
 were presented with one of the possible 741 pairs of sounds, and were
 asked to rate how similar they were on a scale of “very similar” to “very
 dissimilar.” They could listen to the pair of stimuli as many times as
 necessary before giving a response. Participants were given 10 practice
 trials using a set of 10 vocalisations that were not included in the main
 experiment. The total duration of each session was approximately 120
 minutes. Participants
 performed the emotional ratings and speeded categorisation tasks in
 alternating blocks in the same (final) session. In the ratings task,
 participants rated each stimulus on arousal (low to high), valence
 (negative to positive), and emotional intensity for four emotions
 (anger/disgust/fear/pleasure, low to high). In all ratings tasks, data
 were coded on a scale of 0 (low) to 1 (high). In the categorisation task,
 participants were instructed to identify as quickly as possible the
 emotion expressed for each stimulus as being anger, disgust, fear, or
 pleasure. The association between a particular emotion and a particular
 response button was randomised for each block. Before the session began,
 participants were given 10 practice trials for both the rating and
 categorisation task. Participants were familiarised to the entire stimulus
 set before the first block for each speaker. The emotion
 ratings and categorisation session consisted of 12 blocks, incorporating 6
 blocks of each task (rating and categorisation). Each task was repeated
 three times for each of the two speakers (1 male, 1 female), and data were
 averaged across the three repetitions. One block contained all 39 stimuli
 for one speaker, and stimulus order was randomised for each participant.
 Speaker gender order and task order were pseudo-randomised for each
 participant, such that each gender and each task could only appear a
 maximum of twice in a row. The total duration of the session was
 approximately 120 minutes.

title: Tote Road Pike Lakes restoration: northern pike eradication

description: This data was collected during the period of 2016-2019 in support of an
 invasive northern pike and muskeullunge eradication project
 at eight lakes near Soldotna, Alaska collectively known as the
 Tote Road Pike Lakes.  The data represents information on lake
 water quality, gillnetting effort and catch and catch sampling. The
 dataset also includes data on the capture and relocation of native fish
 (rainbow trout and juvenile coho salmon) collected from Soldotna Creek (a
 Kenai River tributary) and released into the eight Tote Road area lakes to
 provide for an alternate fishery following the removal of
 invasive northern pike and muskeullunge using the chemical
 rotneone. 
description: Water quality data was collected with a Quanta Hydrolab.  Water
 quality measurements were collected in one-meter water increments from the
 lake bottom to lake surface.  Water quality was collcted from each lake on
 a quasi-monthly basis for one year before and one year after the rotenone
 treament of each lake. Calibration of the Hydrolab was done according to
 the manufacturer's guidelines. Gillnetting and
 fish sampling data was collected during northern pike and muskelluenge
 removal activities in 2018 and also from gillnettting in 2019 done to
 verify the success of invasive fish eradication attempts via rotenone
 treatment. Gillnets were variable mesh gillnets paneled with six 20-foot
 sections of three-quarter in, 1 in, 1¼ in, 1½ in, 1¾ in, and 2 in stretch
 monofilament mesh. Fish lengths were measured from fork-of-tail to tip-of
 -snout. Some fish caught in the spring of 2018 were sampled for spawning
 condition and sex identificatiion based on morphological traits observed
 during dissection. All data was manually entered into
 Microsoft Excel files then error-checked for typos and out-of-range values
 before converting to .csv file format.

title: Leaf size of woody dicots predicts ecosystem primary productivity

description: A key challenge in ecology is to understand the relationships between
 organismal traits and ecosystem processes. Here, with a novel dataset of
 leaf length and width for 10,480 woody dicots in China and 2,374 in North
 America, we show that the variation in community mean leaf size is highly
 correlated with the variation in climate and ecosystem primary
 productivity, independent of plant life form. These relationships likely
 reflect how natural selection modifies leaf size across varying climates
 in conjunction with how climate influences canopy total leaf area. We find
 that the leaf size‒primary productivity functions based on the Chinese
 dataset can predict productivity in North America and vice-versa. In
 addition to advancing understanding of the relationship between a
 climate-driven trait and ecosystem functioning, our findings suggest that
 leaf size can also be a promising tool in paleoecology for scaling from
 fossil leaves to paleo-primary productivity of woody ecosystems.
description: This dataset includes two Excel files, one for the data of China
 and the other for the data of North America from different data sources,
 and files for related R code. Both Excel files include leaf size measures
 and environmental variables used in the study entitled as "Leaf size
 of woody dicots predicts ecosystem primary productivity". Data was
 compiled from published floras, the online databases and peer-reviewed
 publications described in the Methods of the paper and Data supplement in
 the appendices. Leaf size measures were calculated by integrating species
 distributions with the median leaf length, leaf width and 2/3*length-width
 products per species separately. Each environmental layer was resampled
 into the same resolution as those of species distributions in China and
 North America (see Data supplement for details).

title: Using Environmental DNA to detect a dangerous carnivore

description: Negative human-wildlife interactions can be better managed by early
 detection of the wildlife species involved. However, many animals that
 pose a threat to humans are highly cryptic and detecting their presence
 before the interaction occurs can be challenging. Here we describe a
 method whereby the presence of a dangerous animal, the estuarine crocodile
 (Crocodylus porosus) was detected using traces of DNA shed into the water,
 known as environmental DNA (eDNA). The estuarine crocodile is present in
 waterways throughout South-East Asia and Oceania and has been responsible
 for over a thousand attacks upon humans in the past decade. A critical
 factor in the crocodile’s capability to attack humans is their ability to
 remain hidden in turbid waters for extended periods, ambushing humans that
 enter the water or undertake activities around the waterline. In northern
 Australia, we sampled water from tanks we crocodiles were present or
 absent, and were able to discriminate the estuarine crocodile from a
 closely related sympatric species that does not pose a threat to humans,
 the freshwater crocodile (Crocodylus johnstoni). Further, we could detect
 the presence of the estuarine crocodile within an hour of its entry and up
 to 72 hours the crocodiles were removed from the tanks. We conclude that
 eDNA could be a valuable tool for reducing human-wildlife conflict through
 early detection of the species in question.

title: Targeting diamondback moth in greenhouses by attracting specific native parasitoids with herbivory-induced plant volatiles

description: We investigated whether recruitment of specific parasitoids
 using a specific blend of synthetic herbivory-induced plant
 volatiles (HIPVs) could be a novel method of pest control in
 greenhouses. In the Miyama rural area in
 Kyoto, Japan,diamondback moth (DBM) (Plutella xylostella) larvae
 are an important pest of cruciferous crops in greenhouses,
 and Cotesia vestalis, a larval parasitoid of DBM, are
 found in the surrounding areas. Dispensers of HIPVs that
 attracted C. vestalis and honey feeders were set inside
 greenhouses (treated greenhouses). The monthly incidence of DBM
 in the treated greenhouses was significantly lower than that in the
 untreated greenhouses across a two-year period. The monthly
 incidences of C. vestalis and DBM were not significantly
 different in the untreated greenhouses, whereas the monthly
 incidence of C. vestalis was significantly higher than
 that of DBM in the treated greenhouses. Poisson regression analyses showed
 that, in both years, a significantly higher number of C.
 vestalis was recorded in the treated greenhouses than in the
 untreated greenhouses when the number of DBM adults increased. We
 concluded that DBM was suppressed more effectively by C.
 vestalis in the treated greenhouses than in the untreated
 greenhouses.

title: Data from: Optimisation of biogenic synthesis of silver nanoparticles from flavonoid-rich Clinacanthus nutans leaf and stem aqueous extracts

description: BACKGROUND: Silver nanoparticles (AgNPs) are widely used in food
 industries, biomedical, dentistry, catalysis, diagnostic biological
 probes, and sensors. The use of plant extract for AgNPs synthesis
 eliminates the process of maintaining cell culture and the process could
 be scaled up under a non-aseptic environment. The purpose of this study is
 to determine the classes of phytochemicals, to biosynthesise and
 characterise the AgNPs using Clinacanthus nutans leaf and stem extracts.
 In this study, AgNPs was synthesised from the aqueous extracts of C.
 nutans leaves and stems through a non-toxic, cost effective and
 eco-friendly method. RESULTS: The formation of AgNPs was confirmed by
 UV-Vis spectroscopy, and the size of AgNP-L (leaf) and AgNP-S (stem) were
 114 and 129 nm, respectively. Transmission electron microscopy (TEM)
 analysis showed spherical nanoparticles with AgNP-L and AgNP-S ranging
 from 10-300 nm and 10-180 nm; with zeta potentials of AgNP-L and AgNP-S at
 -42.8 and -43.9 mV, respectively. XRD analysis matched the face-centred
 cubic structure of silver and was capped with bioactive compounds. FTIR
 analysis revealed the presence of few functional groups of phenolic and
 flavonoid compounds. These functional groups act as reducing agents in
 AgNPs synthesis. CONCLUSION: This result showed that the biogenically
 synthesised nanoparticles reduced silver ions to silver nanoparticles in
 aqueous condition and the AgNPs formed were stable and less toxic.

title: Data from: A novel real-world ecotoxicological dataset of pelagic microbial community responses to wastewater

description: Real-world observational datasets that record and quantify
 pressure-stressor-response linkages between effluent discharges and
 natural aquatic systems are rare.  With global wastewater volumes
 increasing at unprecedented rates, it is urgent that the present dataset
 is available to provide the necessary information about microbial
 community structure and functioning.  Field studies were
 performed at two time-points in the Austral summer. 
 Single-species and microbial community whole effluent toxicity (WET)
 testing was performed at a complete range of effluent concentrations and
 two salinities, with accompanying environmental data to provide new
 insights into nutrient and organic matter cycling, and to identify
 ecotoxicological tipping points.  The two salinity regimes were
 chosen to investigate future scenarios based on a predicted salinity
 increase at the study site, typical of coastal regions with rising sea
 levels globally.  Flow cytometry, amplicon
 sequencing of 16S and 18S rRNA genes and micro-fluidic
 quantitative polymerase-chain reactions (MFQPCR) were used to determine
 chlorophyll-a and total bacterial cell numbers and size, as well as
 taxonomic and functional diversity of pelagic microbial
 communities.  This strong pilot dataset could be
 replicated in other regions globally and would be of high value to
 scientists and engineers to support the next advances in microbial
 ecotoxicology, environmental biomonitoring and estuarine water quality
 modelling.
description: Refer to ReadMe files included with the dataset.
description: In this study, bacterial cell
 densities were quantified in the microbial WET tests from frozen samples
 several months after the initial flow cytometry was done using fresh
 samples.  Previous studies have reported decreases in bacterial (Kamiya et
 al., 2007) cell densities between natural and frozen samples.  Therefore,
 these data are recommended for assessment of relative differences between
 samples since they may reflect a slight underestimation of the bacterial
 relative to algal cell chlorophyll-a contributions. While a number of studies have
 found that MFQPCR produces copy number estimates that are directly
 comparable to those produced with traditional qPCR (Ishii et al., 2014a,
 Byappanahalli et al., 2015), variations in reaction efficiency are common
 between samples from different sites (Brankatschk et al., 2012), and in
 MFQPCR these differences in efficiency may be substantial (Crane et al.,
 2018).  Therefore, whilst copy number tables presented in the data records
 are suitable for intra-study comparisons and modelling, it is recommended
 that the raw data files are utilised in studies intending to combine
 inter-study datasets, and uniform efficiency cut-offs be applied prior to
 further analysis.
