title: Incremental Carbon, Oxygen, and Strontium Isotope Data from Modern and Archaeological Human Canine and Molar Enamel.

description: This dataset contains high-resolution incremental enamel isotope (δ13C, δ18O, and 87Sr/86Sr) and strontium concentration ([Sr]) measurements from 28 human teeth (canines, 1st molars, and 3rd molars) sampled from 10 individuals. Nine individuals derive from a modern forensic context in Belgium, and one from the Bronze Age archaeological site of Staje, Slovenia (748–406 cal BC). The study adapts the Plomp et al. (2020) molar protocol onto first and third molars, incorporating an additional increment near the enamel–root junction, and introduces a new standardised hand-drilled incremental sampling method for canines based on their enamel growth structures. Canines produced up to four minimally overlapping increments, while molars exhibited greater overlap due to complex growth and wear. This dataset supports the development of a replicable, standardised methodology for incremental enamel isotope sampling of human canines, as well as the refinement and increased resolution of incremental enamel sampling of human molars

title: Sequential dentine δ13C and δ15N isotope data from human teeth with evidence of vitamin D deficiency from the Netherlands and Belgium (17th–19th centuries AD)

description: This dataset presents sequential carbon (δ13C) and nitrogen (δ15N) isotope measurements from human dentine to assess potential isotopic variation associated with the presence of interglobular dentine (IGD). The dataset comprises nine teeth (eight first molars and one canine) from nine individuals dated to the 17th–19th centuries AD; five from the cemeteries of Hattem and Beemster (the Netherlands), and four from the Church of St. Anne, Koekelberg (Belgium). IGD had previously been identified in eight of the teeth, while one tooth held no evidence of IGD. Serial dentine samples were obtained using two commonly applied incremental methodologies; micro-slicing and micro-punching, to generate high-resolution δ13C and δ15N sequences along the growth axis of each tooth. Incremental δ13C values range from -21.4‰ to -18.8‰, and δ15N values from 9.3‰ to 18.2‰. The results indicates that IGD, and accordingly vitamin D deficiency, has a minimal effect on δ13C and δ15N values from human dentine, and does not affect the incremental sampling conclusions on diet and weaning.

title: Sulfur isotopes evidence spatial ecology of Late Pleistocene ungulates in southwestern France

description: Understanding prey species spatial behaviour is key to unravelling contemporary hunter-gatherer subsistence and movement patterns. Here, we use sulfur (δ34S), carbon (δ 13C) and nitrogen (δ 15N) isotope compositions of bone collagen extracted from Rangifer, Equus, Bovinae, Capreolus, and Cervus (n = 244) to explore isotope spatial and dietary niches of several key hunter-gatherer prey species from three Late Pleistocene sites in southwestern France between MIS 5 and MIS 3. Alongside morphological identification, Zooarchaeology by Mass Spectrometry (ZooMS) was used to confirm deer taxa (n = 125) allowing for a better interpretation of the isotopic data. δ34S analysis identifies differences in ranging sizes between ungulates with known large ranging sizes from those with small to medium size ranges. Rangifer, who, today, have large home ranges, have the largest range of δ34S values and lowest δ34S values with low to no overlap with other ungulate species through time. This indicates that Rangifer had a larger range size with a distinct isotopic area that is different to other ungulates, potentially farther inland and farther north. Bovines and Equus have largely overlapping δ34S values that are similar to the modern local δ34S value of the sites, and Cervus and Capreolus have δ34S values that overlap but are slightly higher than the modern δ34S values, potentially indicating a ranging area to the west of the sites. These results reveal that Neanderthals hunted three different groups of game who occupied different areas of the landscape.

title: Stable carbon and nitrogen isotope dataset from Roman sites in Germania Inferior (Xanten, Tongeren, and Valkenburg)

description: Stable isotope collagen data (δ¹³C, δ¹⁵N) are presented for human and faunal samples from three major Roman sites in Germania Inferior: Xanten (Colonia Ulpia Traiana, Germany), Tongeren (Atuatuca Tungrorum, Belgium), and Valkenburg-Marktveld (Praetorium Agrippinae, the Netherlands). Isotopic results are reported for 48 samples (representing 32 human individuals and 10 faunal specimens) that met standard collagen quality criteria (yield, C%, N%, C:N ratios). For the Xanten site, 14 individuals were analysed, including 5 individuals for whom both bone and dentine collagen were measured. All faunal remains originate from Xanten. Furthermore, 17 individuals are included from Tongeren (representing three locations: Beukenbergweg, Kielestraat, and ZW Grafveld), and one individual from the Valkenburg site. This dataset expands the isotopic records for the North-Western Roman Frontier, supporting research on Roman dietary practices and human-animal interactions.

title: Sex education and sexual health knowledge predicting belief in sexual myths in college students attending a mid-level university in Southeastern Louisiana.

description: Comprehensive sex education has many positive outcomes compared to abstinence-only sex education, such as reduction in adolescent risk behaviours, increased respect of sexual orientation and gender diversity, and more. A direct goal of sex education is to increase students’ knowledge of sexual health. One harmful consequence of abstinence-only sex education and a lack of sexual health knowledge is the belief in sexual myths. Sexual myths spread due to misinformation, and can be reduced by increasing sexual health knowledge. The present study conducted a hierarchical multiple regression to assess the potential influence of sex education and sexual health knowledge on belief in sexual myths. The sample consisted of undergraduate college students (n = 187). The survey included a Sexual Health Education Questionnaire, Sexual Health Knowledge Scale, Sexual Myths Scale, and demographic questions. The majority of the sample received less comprehensive sex education. Sexual health knowledge and belief in sexual myths were found to be significantly negatively correlated, along with sexual health knowledge and religiosity. Religiosity and belief in sexual myths were found to be significantly positively correlated. Gender, religiosity, sexual health knowledge, and sex education were found to predict 21.5% of the variance in one’s belief in sexual myths.

title: Patch-walking electrophysiology recordings

description: Significant technical challenges exist when measuring synaptic connections
 between neurons in living brain tissue. The patch clamping technique, when
 used to probe for synaptic connections, is manually laborious and
 time-consuming. To improve its efficiency, we pursued another approach:
 instead of retracting all patch clamping electrodes after each recording
 attempt, we cleaned just one of them and reused it to obtain another
 recording while maintaining the others. With one new patch clamp recording
 attempt, many new connections can be probed. By placing one pipette in
 front of the others in this way, one can “walk” across the mouse brain
 slice, termed “patch-walking.” We performed 136 patch clamp attempts for
 two pipettes, achieving 71 successful whole cell recordings (52.2%). Of
 these, we probed 29 pairs (i.e., 58 bidirectional probed connections)
 averaging 91 μm intersomatic distance, finding 3 connections.
 Patch-walking yields 80-92% more probed connections, for experiments with
 10-100 cells than the traditional synaptic connection searching method.

Zip file includes electrophysiology recordings in .abf files where all neurons patched were tested with current clamp (IC) protocols to study synaptic connectivity. 42 .abf files are included in the zip that represent the connectivity matrix described in Figure 3 described in the Patch-walking paper. Naming convention is "23512###" with the ### representing each current clamp protocol run. Each pre-synaptic neuron was probed with 3 traces while reading the electrical output of the post-synaptic neuron and vice versa. The .abf files can be viewed in the [pClamp Software Suite](https://www.moleculardevices.com/products/axon-patch-clamp-system/acquisition-and-analysis-software/pclamp-software-suite) provided by Molecular Devices or alternatively can be viewed and analyzed in Python using the [pyABF library](https://github.com/swharden/pyABF).  Data is structured by date and the numeral of each file is a new sweep of IC protocol. Data collected from the patcherBot for patch-walking was based on code through autopatcher.org. Alternatively, for semi-automated patch clamping, users may use pipette cleaning as a method for reuse of pipettes ([https://github.com/mightenyip/Pipette-Cleaning-Software](https://github.com/mightenyip/Pipette-Cleaning-Software)). Current clamp and voltage clamp protocols were established as described by the Allen Institute for Brain Science.

title: Data accompanying <i>An illustrative case for muscular fatigue-resistance underlying exaggerated begging in avian brood parasites</i><i> </i>

description: Food-solicitation displays are critical for offspring survival and can become evolutionarily exaggerated due to sibling rivalry or parental conflict. Avian brood parasites represent extreme cases of these conflicts, using exaggerated begging displays to outcompete host offspring. Yet, we know little about the physiology underlying such traits. Here, we investigated an interesting case of competitive begging asymmetry in brown-headed cowbirds (<i>Molothrus ater</i>) and host prothonotary warbler (<i>Protonotaria citrea</i>). Through behavioral assays we found cowbirds beg far longer than warblers, while each species’ nestlings initiate begging at similar speeds. Meanwhile, complementary <i>in situ</i> muscle stimulation assays suggested that these effects were due to greater fatigue-resistance in cowbirds, compared to their host. While cowbirds and warblers represent only one evolutionary origin of obligate brood parasitism, our findings present a compelling path for future comparative work to explore muscular fatigue-resistance as a key physiological innovation that facilitates competitive begging success in parasitic chicks.
