title: Spatial and temporal variation in toxicity and inorganic composition of hydraulic fracturing flowback and produced water

description: Hydraulic fracturing for oil and gas extraction produces large volumes of
 wastewater, termed flowback and produced water (FPW), that are highly
 saline and contain a variety of organic and inorganic contaminants. In the
 present study, FPW samples from ten hydraulically fractured wells, across
 two geologic formations were collected at various timepoints. Samples were
 analyzed to determine spatial and temporal variation in their inorganic
 composition. Results indicate that FPW composition varied both between
 formations and within a single formation, with large compositional changes
 occurring over short distances. Temporally, all wells showed a
 time-dependent increase in inorganic elements, with total dissolved solids
 increasing by up to 200,000 mg/L over time, primarily due to
 elements associated with salinity (Cl, Na, Ca, Mg, K). Toxicological
 analysis of a subset of the FPW samples showed median lethal
 concentrations (LC50) of FPW to the aquatic invertebrate Daphnia
 magna were highly variable, with the LC50 values ranging from
 1.16% to 13.7% FPW. Acute toxicity of FPW significantly correlated with
 salinity, indicating salinity is a primary driver of FPW toxicity, however
 organic components also contributed to toxicity. This study provides
 insight into spatiotemporal variability of FPW composition and illustrates
 the difficulty in predicting aquatic risk associated with FPW.

title: Observation of mHz-level cooperative Lamb shifts in an optical atomic clock

description: We report on the direct observation of resonant electric dipole-dipole
 interactions in a cubic array of atoms in the many-excitation limit. The
 interactions, mediated by single-atom couplings to the shared
 electromagnetic vacuum, are shown to produce spatially-dependent
 cooperative Lamb shifts when spectroscopically interrogating the mHz-wide
 optical clock transition in strontium-87. We show that the
 ensemble-averaged shifts can be suppressed below the level of evaluated
 systematic uncertainties for state-of-the-art optical atomic clocks.
 Additionally, we demonstrate that excitation of the atomic dipoles near a
 Bragg angle can enhance these effects by nearly an order of magnitude
 compared to non-resonant geometries. Given the remarkable precision of
 frequency measurements and the high accuracy of the modeled response, our
 work demonstrates that such a clock is a novel platform for studies of the
 quantum many-body physics of spins with long-range interactions mediated
 by propagating photons.

title: Bacterial 16s rRNA gene amplicon data (V3-V4) and qPCR data

description: Within a given species, considerable inter-individual, spatial, and
 temporal variation in the composition of the host microbiome exists. In
 group-living animals, social interactions homogenize microbiome
 composition among group members, nevertheless, divergence in microbiome
 composition among related groups arises. Such variation can result from
 deterministic and stochastic processes. Stochastic changes, or ecological
 drift, can occur among symbionts with potential for colonizing a host and
 within individual hosts, and drive divergence in microbiome composition
 among hosts or host groups. We tested whether ecological drift associated
 with dispersal and foundation of new groups cause divergence in microbiome
 composition between natal and newly formed groups in the social spider
 Stegodyphus dumicola. We simulated initiation of new groups and compared
 variation in microbiome composition among and within groups. Theory
 predicts a decrease in beta diversity with increasing group size, and we
 found that single founders harboured the highest diversity. Divergence in
 microbiome composition from the natal nest was mainly driven by a higher
 number of non-core symbionts. This suggests that stochastic divergence in
 host microbiomes can arise during the process of group formation by
 individual founders, which could explain the existence of among-group
 variation in microbiome composition in the wild. Consistent host-symbiont
 relationships in the species must then be maintained by other processes.
 Individual founders harboured higher relative abundances of non-core
 symbionts some of which are possible pathogens, compared with founders in
 small groups. These symbionts vary in occurrence with group size,
 indicating that group dynamics influence various core and non-core
 symbionts differently.

title: Reinforcement-based processes actively regulate motor exploration along redundant solution manifolds

description: From a baby’s babbling to a songbird practicing a new tune, exploration is
 critical to motor learning. A hallmark of exploration is the emergence of
 random walk behaviour along solution manifolds, where successive motor
 actions are not independent but rather become serially dependent. Such
 exploratory random walk behaviour is ubiquitous across species, neural
 firing, gait patterns, and reaching behaviour. Past work has suggested
 that exploratory random walk behaviour arises from an accumulation of
 movement variability and a lack of error-based corrections. Here we test a
 fundamentally different idea—that reinforcement-based processes regulate
 random walk behaviour to promote continual motor exploration to maximize
 success. Across three human-reaching experiments, we manipulated the size
 of both the visually displayed target and an unseen reward zone, as well
 as the probability of reinforcement feedback. Our empirical and modelling
 results parsimoniously support the notion that exploratory random walk
 behaviour emerges by utilizing knowledge of movement variability to update
 intended reach aim towards recently reinforced motor actions. This
 mechanism leads to active and continuous exploration of the solution
 manifold, currently thought by prominent theories to arise passively. The
 ability to continually explore muscle, joint, and task redundant solution
 manifolds is beneficial while acting in uncertain environments, during
 motor development, or when recovering from a neurological disorder to
 discover and learn new motor actions.

title: Data for: A novel and enhanced calibration of the tilting weir as a flow measurement structure

description: To achieve reliable and equitable water distribution it is necessary to
 accurately estimate the volumetric discharge of water flow through rivers
 and canals. One such method of accomplishing this is by using hydraulic
 structures, such as the tilting weir. This structure not only can be used
 to measure the discharge of water on a continuous basis, but also allows
 for regulating the water level upstream of the structure. Presently,
 tilting weirs are often used to control water levels, but the literature
 on their utilization as flow measurement structures has remained sparse.
 This study presents a thorough analysis of laboratory experiments on
 scaled models of tilting weirs, where the flow depth upstream of the
 structure (i.e., head) and the inclination angle are used to calibrate an
 equation to estimate the discharge to a high degree of accuracy.
 Operational guidelines to ensure minimum uncertainty in measurement are
 also given. The data published here include head and discharge
 measurements for all experiments conducted, including information on the
 experimental location, date, and model dimensions. Publication of this
 data is intended to allow other researchers to verify the calibration
 procedure laid out in the primary article, and as a comparative dataset
 for future calibrations.

title: Data from: Infrared barriers as a detection tool to reduce human-elephant conflicts

description: Elephant incursions into farms represent an important challenge for local
 communities and farmers living around protected areas, but also for the
 long-term conservation of elephants. Early detection of elephants is a
 promising technique to reduce elephant presence in farms and human
 settlements reducing human elephant interactions. In this study we
 investigated the potential of infrared barriers to detect African savannah
 elephants (Loxodonta africana). We designed and tested battery-operated
 photoelectric beam sensors in 12 locations of southern Tanzania and
 assessed the elephant detection accuracy through camera trapping for a
 total of 246 days. We obtained 1803 recordings of wildlife crossing the
 barriers range (30 different species of mammals and several bird and bat
 species). Our results show that infrared barriers, when located at
 1.75-2.2 m high, detect 100% of adult elephants and ∼29% of subadult
 elephants. Giraffes were the only other wildlife species detected by the
 barriers. Interestingly, large vehicles were also detected, which might be
 helpful to prevent motorized poaching. Given the gregarious behaviour of
 elephant families, and the limited access for vehicles, infrared barriers
 may represent an interesting and cost-effective detection system for early
 warning strategies in elephant-dominated areas of Africa and Asia or for
 other large-sized visitors.

title: Tudor genes of Holozoa: Early evolution and within Metazoa diversification of a multifaceted protein family

description: Early metazoan evolution was characterized by the expansion of many gene
 families involved in novel multicellularity-related functions, like the
 Tudor family. In eukaryotes, Tudor genes are numerous and heterogeneous,
 mostly associated with gene expression regulation. However, the family
 underwent a lineage-specific expansion in animals, with novel elements
 almost exclusively involved in the germline-specific regulation of
 retrotransposons through piRNAs (as spatiotemporal regulators of the
 key-element Piwi, another previously supposedly animal-specific gene). In
 the present analysis, we used online-available proteomes for a total of 25
 major taxonomic groups to characterize the Tudor gene family at a
 holozoan-wide level, and we confirmed the apomorphic expansion of
 piRNA-related Tudor genes in animals. However, we could also interestingly
 observe the presence of elements of the piRNA pathway, both Tudor and Piwi
 genes, in some Ichthyosporea species, suggesting that some elements of the
 pathway were already present in the last common ancestor of Holozoa.
 Moreover, we observed an outstanding variability (34-fold) of Tudor gene
 number both between and within metazoan phyla, that could be associated
 with convergent genomic and phenotypic evolutions. Expansions were usually
 sided by whole genome duplications and/or life history traits such as
 parthenogenesis, possibly leading to the expansion of retrotransposon
 silencing pathways. Reductions were instead mostly associated with overall
 phenotypic and genomic simplifications, like almost all endoparasites of
 our dataset. Lastly, we phylogenetically tested a previously proposed
 model for the evolution of the three possible secondary structures of the
 Tudor domains and we could mostly (but not completely) confirm the model.
