title: Data from: Diversity of land snail tribe Helicini (Gastropoda: Stylommatophora: Helicidae): where do we stand after 20 years of sequencing mitochondrial markers?

description: Sequences of mitochondrial genes revolutionized the understanding of
 animal diversity and continue to be an important tool in biodiversity
 research. In the tribe Helicini, a prominent group of the western
 Palaearctic land snail fauna, mitochondrial data accumulating since the
 2000s helped to newly delimit genera, inform species-level taxonomy, and
 reconstruct past range dynamics. We combined the published data with own
 unpublished sequences and provide a detailed overview of what they
 revealed about the diversity of the group. The delimitation of Helix is
 revised by placing Helix godetiana back in the genus and new synonymies
 are suggested within the genera Codringtonia and Helix. The spatial
 distribution of intraspecific mitochondrial lineages of several species is
 shown for the first time. Comparisons between species reveal considerable
 variation in distribution patterns of intraspecific lineages, from broad
 postglacial distributions to regions with a fine-scale pattern of
 allopatric lineage replacement. To provide a baseline for further research
 and information for anyone re-using the data, we thoroughly discuss the
 gaps in the current dataset, focusing on both taxonomic and geographic
 coverage. Thanks to the wealth of data already amassed and the relative
 ease with which they can be obtained, mitochondrial sequences remain an
 important source of information on intraspecific diversity over large
 areas and taxa.

title: Sex-specific shifts in morphology and diet in a frog after 50 years of anthropogenic habitat fragmentation

description: Aim: Phenotypic shifts are commonly observed when animals face insular
 habitat change and may reflect ongoing stresses on individuals. However,
 the generality and the driving processes of this ‘island rule’ remain
 equivocal, notably in amphibians. Here, we investigate both morphological
 and dietary shifts in a frog using a mosaic of human-created islands to
 assess the potential operating mechanisms underlying these phenotypic
 responses. Location: Thousand Island Lake, China. Taxon: The Chinese
 piebald odorous frog, Odorrana schmackeri. Results: We found insular
 dwarfism in female but not male frogs. Meanwhile, insular females also had
 smaller gape widths after accounting for snout-vent lengths (SVLs) than
 mainland females. According to SEMs, resource availability had a direct
 positive effect on body size. Finally, diet composition differed between
 island and mainland populations, but only in females. Males and females on
 islands exhibited greater overlaps in diet. Main conclusions: In contrast
 with most studies in amphibians, we found insular dwarfism rather than
 gigantism in females. The smaller gape width after accounting for SVL in
 insular females suggests potential changes in prey utilization or food
 availability on these human-created islands. This notion is further
 supported by the differentiation of diet composition between island and
 mainland females. The higher diet overlap between sexes implies stronger
 intersexual competition for food resources after habitat fragmentation.
 Overall, we found shifts in morphology and diet in frogs which may
 implicate the influence of habitat fragmentation and underscores the need
 to consider intersexual differences when assessing responses of species to
 anthropogenic disturbances.
description: We compared body size between insular and mainland populations
 and between sexes. We examined the potential underlying mechanisms
 regarding body size shifts using structural equation modelling (SEM).
 Finally, we analyzed changes in diet composition and compared intersexual
 diet overlap between island and mainland sites.

title: Mixed-species flocking is associated with low arthropod detectability and increased foraging efficiency by Yungas forest birds in Argentina

description: Mixed-species flocks presumably provide birds with antipredator and
 foraging benefits. The foraging benefits hypothesis predicts that a
 reduction in arthropod abundance will trigger flocking activity; however,
 flocking activity may also be influenced by the difficulty of detecting
 arthropods, a seldom explored possibility. We found that environmental
 traits (temperature and foliage density) combined with arthropod abundance
 explained arthropod detection by birds in the Yungas foothill forest of NW
 Argentina. Prey detection was inversely related to ambient temperature and
 foliage density while positively associated with arthropod abundance.
 Based on this result, we built a structural equation model using a latent
 proxy variable for arthropod detectability, arthropod crypsis, integrating
 ambient temperature, foliage density, and proportion of immature
 arthropods. This model allowed us to compare the relative importance of
 arthropod abundance and the difficulty in detecting prey items as
 predictors of flocking propensity. After two years of studying 129
 mixed-species flocks, 1,344 bird foraging sequences, and 25,591 arthropod
 captures, we found that the flocking propensity of birds was only
 significantly correlated with arthropod detectability and not with
 arthropod abundance. Flocking propensity peaked when the arthropod
 community was comprised of proportionately more immature and non-flying
 arthropods, the temperature was low, and the foliage cover was more dense;
 all factors are contributing to a low arthropod detectability. Finally, we
 evaluated whether joining mixed-species flocks provided foraging benefits
 such as increased foraging efficiency. Individuals benefited from joining
 flocks by an average increase of their prey-capture attempt rate of 40%,
 while the search rate increased by 16%. Our results add a new perspective
 on the drivers of mixed-species flocking by showing that the capacity to
 find prey items may have a more significant effect than prey abundance per
 se.

title: A tail of plumage colouration: disentangling geographic, seasonal, and dietary effects on plumage colour in a migratory songbird

description: Plumage ornamentation in birds serves critical inter- and intra-sexual
 signaling functions. While carotenoid-based plumage colouration is often
 viewed as a classic condition dependent sexually selected trait, plumage
 colouration can be influenced by a wide array of both intrinsic and
 extrinsic factors. Understanding the mechanisms underlying variation in
 colouration is especially important for species where the signaling
 function of ornamental traits is complex or the literature conflicting.
 Here, we examined variation in the yellow/orange tail feathers of American
 redstarts (Setophaga ruticilla) passing through two migratory stopover
 sites in eastern North America during both spring and fall migration to
 assess the role of geographic variation and seasonality in influencing
 feather colouration. In addition, we investigated whether diet during
 moult (inferred via stable isotope analysis of feather δ15N and δ13C)
 influenced plumage colouration. Our findings indicate that geographic
 variation, season, and diet all influence individual differences in
 American redstart colouration, represented by both traditional and
 tetrahedral colour variables. The extent to which these factors influence
 colour expression however is largely dependent on the colour metric under
 study, likely because different colour metrics reflect different
 attributes of the feather (e.g., structural components vs. pigment
 deposition). The effects of diet (δ15N) and season were pronounced for
 brightness, suggesting a strong effect of diet and feather
 wear/degradation on feather structure. Though hue, a metric that should
 strongly reflect pigment deposition, also changed from spring to fall,
 that effect was dependent on age, with only adults experiencing a
 reduction in ornamentation. Taken together, our results highlight the
 numerous sources of variation behind plumage coloration and underscores
 the difficulty of unraveling complex visual signaling systems, such as
 those in American redstarts.

title: Healthy beverage initiatives: A case study of scenarios for optimizing their environmental benefits on a university campus

description: The association between consumption of sugar sweetened beverages (SSBs)
 and diseases including diabetes, liver disease and dental disease is well
 known, yet SSBs continue to be aggressively promoted, including on
 university campuses. Healthy beverage initiatives (HBIs) are focused on
 improving health by decreasing consumption of SSBs. Some HBIs also aim to
 improve environmental sustainability, e.g. by substituting tap water for
 SSBs, including the HBI on the 10 campuses of the University of
 California. However, there is no study of HBIs’ potential environmental
 benefits. To address this knowledge gap we carried out an environmental
 life cycle assessment of greenhouse gas emissions, blue water use, and
 plastic pollution for both liquid content and container for the 940,773
 liters of beverages consumed in one calendar year at the University of
 California, Santa Barbara. We found that climate and water impacts per
 liter for liquid contents of 10 SSB beverage types and the non-SSB
 versions of these 10 types without added sugar, were very similar and
 larger than that of the containers. Impacts of six container types varied
 widely, with climate impact highest for glass, and blue water and plastic
 impact highest for plastic containers, while aluminum had higher climate
 impact than plastic. We then evaluated the environmental benefits of 12
 counterfactual HBI scenarios with different combinations of container
 types and liquid beverages for SSBs, non-SSBs, bottled water, and tap
 water. The scenario that replaced all other beverages with tap water
 eliminated almost all environmental impacts, while scenarios that reduced
 SSBs but increased beverages other than tap water took back many benefits
 of reduced SSBs. Our results show that to optimize potential environmental
 benefits, HBIs need to emphasize reducing consumption of all commercial
 beverages and replacing them with tap water, which will also optimize
 health benefits. Our methods and results will be valuable for higher
 education, other institutions, and communities seeking to maximize both
 health and environmental benefits of healthy beverage policies.
description: UCSB dining provided data for 2213 beverage purchases for one
 calendar year (2018-2019), comprising item name, purchasing unit (number
 and size of beverage containers), number of units, container material, and
 purchase location (vending machine, all other). To these categories we
 added mixing ratio (for fountain drinks), SSB (sugar sweetened beverage)
 status, beverage type and sugar content for three categories of sugar
 (added, non-added, unspecified) based on our research.

title: Data from: Sperm metabolic rate predicts female mating frequency across Drosophila species

description: Female mating rates vary widely, even among closely related species, but
 the reasons for this variation are not fully understood.
 Across Drosophila species, female mating frequencies are
 positively associated with sperm length. This association may be due in
 part to sperm limitation, with longer-spermed species transferring fewer
 sperm, or to cryptic female choice. However, a previously overlooked
 factor is sperm metabolic rate, which may correlate with sperm length. If
 faster-metabolizing sperm accumulate age-related cellular damage
 more quickly, then females should remate sooner to obtain fresh sperm.
 Alternatively, frequent female mating may select for increased
 sperm competitiveness via increased metabolism. Here, we measure
 sperm metabolism across
 13 Drosophila species and compare these
 measures to published data on female mating rate and on sperm length.
 Using fluorescent lifetime imaging microscopy, we quantify NAD(P)H
 metabolism ex vivo, in intact organs. Phylogenetically controlled
 regression reveals that sperm metabolic rate is positively associated with
 sperm length and with female mating frequency. Path analysis shows sperm
 length driving sperm metabolism and sperm metabolism either driving or
 being driven by female mating rate. While the causal directionality of
 these relationships remains to be fully resolved, and the effect of sperm
 metabolism on sperm aging and/or sperm competitiveness remains to be
 established, our results demonstrate the importance of sperm
 metabolism in sexual selection.

title: Baltic Sea stable isotope ecology meta-data collection

description: Stable isotope analysis (SIA) has become a pivotal method in food web and
 ecological research, leading to the establishment of the research field
 “stable isotope ecology”. We conducted the first systematic review of
 stable isotope studies in this field in the Baltic Sea macro-region
 (Eglite et al. 2022). The meta-data collection provided here includes the
 information extracted from all 164 studies identified in the systematic
 review across various dimensions (topic, space, time, taxonomic, and
 technical focus), but not primary stable isotope data. The first published
 version of this meta-data collection represents the status as of July 10,
 2021, and was used to filter and extract meta-data to produce the figures
 and tables in the review by Eglite et al. (2022). The meta-data collection
 is a resource for both experienced isotope ecologists and newcomers to
 grasp and access all published Baltic Sea SIA work on any fundamental or
 applied research topic, sub-region, taxon, or trophic group of interest.
 It also represents an ideal foundation for an envisioned "Baltic
 Isobank" database of primary stable isotope data, following the
 vision outlined in Eglite et al. (2022). We will provide regular updates
 of the meta-data collection in the Dryad repository, based on new runs of
 the systematic review query and including any additions of research papers
 and corrections received from the stable isotope ecology community. For
 this purpose, we encourage researchers to inform us about newly published
 research papers employing stable isotopes in the Baltic Sea ecology field
 by sending an e-mail with the publication reference to
 baltic-isobank@geomar.de.
description: This meta-data collection is based on 164 peer-reviewed stable
 isotope articles published in the Baltic Sea ecology field. Each article
 was reviewed in-depth and classified across different dimensions (e.g.,
 topic, space, time, taxonomic focus, and technical focus), but we do not
 provide primary stable isotope data. The studies that have been published
 cover searches from 1992 to 2021 (July 10). 
description: Readme file contains a schematic chart of 12 categories and 43
 corresponding categories for which information was extracted from all 164
 peer-reviewed studies in the "Baltic Sea stable meta-data
 collection" excel flat file. Additionally, we provide researchers
 with examples of how to extract information from this database. This excel
 flat file contains blank cells.

title: Selfee: Self-supervised features extraction of animal behaviors

description: Fast and accurately characterizing animal behaviors is crucial for
 neuroscience research. Deep learning models are efficiently used in
 laboratories for behavior analysis. However, it has not been achieved to
 use an end-to-end unsupervised neural network to extract comprehensive and
 discriminative features directly from social behavior video frames for
 annotation and analysis purposes. Here, we report a self-supervised
 feature extraction (Selfee) convolutional neural network with multiple
 downstream applications to process video frames of animal behavior in an
 end-to-end way. Visualization and classification of the extracted features
 (Meta-representations) validate that Selfee processes animal behaviors in
 a way similar to human perception. We demonstrate that
 Meta-representations can be efficiently used to detect anomalous behaviors
 that are indiscernible to human observation and hint in-depth analysis.
 Furthermore, time-series analyses of Meta-representations reveal the
 temporal dynamics of animal behaviors. In conclusion, we present a
 self-supervised learning approach to extract comprehensive and
 discriminative features directly from raw video recordings of animal
 behaviors and demonstrate its potential usage for various downstream
 applications.

title: Vocal behavior in spotted seals (Phoca largha) and implications for passive acoustic monitoring

description: Passive acoustic methods enable remote monitoring of marine species and
 habitats. These methods can be applied to investigate distribution and
 abundance of populations, to evaluate behavioral and physiological states
 of individuals, and to inform management efforts for animals that live in
 hard-to-reach places. Spotted seals (Phoca largha) inhabit high-latitude,
 light-limited sub-Arctic and Arctic waters and move seasonally with
 unstable sea ice. They are high trophic level predators vulnerable to
 changing conditions associated with environmental warming. At present, an
 incomplete characterization of the spotted seal vocal repertoire limits
 our ability to monitor this species acoustically. Captive studies can
 inform passive acoustic efforts by describing fundamental features of
 species-typical vocalizations emitted by known individuals. These features
 include acoustic parameters as well as developmental, seasonal, and
 sex-specific patterns in vocal behavior. Here, several male spotted seals
 were studied in captivity from age 6 months through adulthood (10 y).
 Vocal behavior was scored daily and opportunistically recorded. The
 production of underwater calls emerged during sexual maturation, at age 4.
 To evaluate vocal repertoire and fine-scale temporal patterns of sound
 production in adult seals, an underwater acoustic recorder was
 continuously deployed with two seals at age 7 years. The spotted seals
 produced at least eight distinctive underwater call types with dominant
 energy below 1 kHz. The amplitude of the most common vocalization was ~140
 dB re 1 μPa (sound pressure level at 1 m). There was a marked peak in
 vocal activity in springtime, prior to onset of the annual molt. This
 period coincided with increased aggressive behavior, presence of a notable
 musky odor, and urogenital swelling indicative of heightened reproductive
 status. These results from developing male spotted seals reared in human
 care confirm the production of recognizable, stereotypic underwater calls
 associated with the breeding season. Description of vocal behavior
 improves knowledge of this species’ biology, and informs the potential use
 of autonomous acoustic recorders to track the presence and movements of
 free-ranging spotted seals in remote habitats.

title: Ventilatory parameters measured in Madagascar hissing cockroaches during continuous gas exchange and DGCs

description: This dataset is presented in the manuscript
 titled: 'Discontinuous gas exchange in
 Madagascar hissing cockroaches is not a consequence of hysteresis
 around a fixed PCO2 threshold'; published in JEB. The
 primary purpose of this investigation was to test if discontinuous gas
 exchange cycles (DGCs) were caused by PCO2 fluctuations
 around ventilatory setpoints. Madagascar hissing
 cockroaches were exposed to normoxic acapnia and treatments of
 either hypoxic acapnia, and normoxic hypercapnia, while
 displaying continious gas exchange, and DGCs. Hemolymph PO2
 and PCO2 were measured in conjunction with ventilatory
 frequency and VCO2 released. This data displays the changes in ventilatory
 parameters observed during ambient gas manipulations.
description: This dataset was collected from Madagascar hissing cockroaches
 displaying continuous gas exchange patterns and discontinuous gas exchange
 cycles (DGCs). Cockroaches were implanted with oxygen and carbon
 dioxide optodes and fixed inside of a flow through respirometry setup with
 their abdomens positioned above an infrared activity detector. Intact
 cockroaches displaying continuous ventilation were exposed to a
 9h treatment of normoxic acapnia, and a 9h treatment of either hypoxic
 acapnia, or normoxic hypercapnia. Cockroaches were then decerebrated to
 trigger sustained DGCs and were exposed to the same treatment of
 manipulated ambient gas tensions. Hemolymph PO<sub>2</sub> and
 PCO<sub>2</sub> fluctuations were measured, along with
 ventilation frequency, and rate of CO<sub>2</sub> release. The
 raw data was recorded onto Labchart software. The
 relevant parameters were identified, and measurements were harvested from
 the raw ventilatory traces. These measurements were processed into the
 Mean, SD, and N values which are reported in the uploaded datasheet's
 'compiled_data' tab. For ease of comparison, the mean values
 recorded in the control gas (normoxic acapnia) and the treatment gas
 (either hypoxic acapnia or normoxic hypercapnia) are paired in univariate
 scatterplots on the other tabs of the datasheet, alongside scatterplots
 illustrating the degrees of change.
description: Exhaled CO<sub>2</sub> could not be measured in
 hypercapnia, and so the cells for these measurements have been blanked
 out. There are also instances of missing values resulting from equipment
 error or experimental limitations, in these instances the cells are left
 empty.
