title: Data from: A late Pleistocene marine glacial refugium in the south-west of Hainan Island, China: Phylogeographical insights from the brown alga Sargassum polycystum

description: Aim: Hainan Island, southern China, is characterized by rich diversity and
 endemism of marine organisms, yet the underpinning mechanisms and
 processes contributing to speciation and diversification are poorly
 understood. Here, the brown alga Sargassum polycystum is used as a model
 to identify putative marine glacial refugia and explore biogeographical
 patterns driven by climate change in the late Pleistocene ice ages.
 Location: South-East Asia. Methods: Mitochondrial cox1 and cox3 and
 nuclear internal transcribed spacer-2 (ITS2) were obtained from 310, 325
 and 313 individuals of S. polycystum (23 localities), respectively.
 Phylogenetic trees (maximum likelihood and Bayesian inference) and
 haplotype/ribotype networks were constructed to elucidate
 phylogeographical patterns. Analysis of molecular variance (AMOVA),
 neutrality tests (Tajima's D and Fu & Li's D*), current
 (θπ) and historical (θw) genetic diversities and extended Bayesian skyline
 plots (EBSP) were used to estimate historical demography. Results: The
 populations from the south-west of Hainan Island harboured much higher
 genetic diversity and unique endemism in comparison with other populations
 in the distribution range. Sargassum polycystum experienced relatively
 long-term stable population size followed by a continued period of
 demographic expansion in the late Pleistocene. Main conclusions: Our
 phylogeographical evidence revealed the existence of a previously
 unidentified marine refugium specific to S. polycystum in the south-west
 of Hainan Island, China (the Central Depression of the Yinggehai Basin),
 along with a possible secondary refugium around the Bali Island,
 Indonesia. These biogeographical findings provide important insights
 regarding speciation, adaptation and evolution of marine organisms in
 South-East Asia and the conservation of unique biodiversity under climate
 change.

title: Data from: Trade-offs in lactation and milk intake by competing siblings in a fluctuating environment

description: Income breeders which forage without their offspring in attendance should
 adjust nursing frequency and the quantity and composition of milk to
 prevailing ecological conditions, and increase the quantity or quality of
 milk transferred if the frequency of nursing visits declines. When milk
 delivery to a litter is insufficient, sibling competition should skew milk
 consumption in favor of dominant litter members. We quantified milk
 nutritional composition and gross energy density, nursing bout durations,
 per capita milk transfer (kg), and milk transfer rate (g/min) per nursing
 bout in singletons and twins in a social carnivore, the spotted hyena. In
 our study population, the energetic cost of lactation is rank dependent
 and particularly high because large fluctuations in local prey abundance
 necessitate long-distance foraging, reducing nursing frequency and
 intensifying sibling competition, more frequently for low-ranking than
 high-ranking females. Females increased milk gross energy density, driven
 by fat content, and increased nursing bout durations as nursing frequency
 declined. Milk transfer increased as social status declined. Females below
 median rank also increased milk transfer as nursing frequency declined.
 Milk transfer was independent of nursing frequency in females above median
 rank and higher for singletons than cubs in twin litters. Dominant
 siblings achieved significantly higher amounts and rates of milk transfer
 than their paired subordinate littermates; this bias increased as sibling
 competition intensified. Our results show how the interplay between
 ecological and social constraints determines the quality and quantity of
 milk transferred, and how socially dominant siblings use aggression to
 skew milk intake in their favor.

title: Data from: Active foraging for toxic prey during gestation in a snake with maternal provisioning of sequestered chemical defenses

description: Many animals sequester dietary defensive compounds and incorporate them
 into the offspring, which protects the young against predation. One
 possible but poorly investigated question is whether females of such
 species actively prey upon toxic diets. The snake Rhabdophis tigrinus
 sequesters defensive steroids from toads consumed as prey; it also feeds
 on other amphibians. Females produce chemically armed offspring in direct
 proportion to their own level of toad-derived toxins by provisioning the
 toxins to their eggs. Our field observations of movements and stomach
 contents of radio-tracked R. tigrinus showed that gravid snakes preyed
 upon toads by actively foraging in the habitat of toads, even though toads
 were a scarce resource and toad-searching may incur potential costs. Our
 Y-maze experiments demonstrated that gravid females were more likely to
 trail the chemical cues of toads than were males or non-gravid females.
 These results showed behavioural switching in females and active foraging
 for scarce, toxic prey during gestation. Because exploitation of toads by
 gravid females results in their offspring being more richly endowed with
 prey-derived toxins, active foraging for toxic prey is expected to be an
 adaptive antipredator trait, which may enhance chemical defence in
 offspring.

title: Data from: Asymmetric dispersal structures a riverine metapopulation of the freshwater pearl mussel Margaritifera laevis

description: Unidirectional water flow results in the downstream-biased, asymmetric
 dispersal of many riverine organisms. However, little is known of how
 asymmetric dispersal influences riverine population structure and
 dynamics, limiting our ability to properly manage riverine organisms. A
 metapopulation of the freshwater pearl mussel Margaritifera laevis may be
 sensitive to river currents because mussels are repeatedly exposed to
 downstream drift during floods—a parasitic life stage is the only, limited
 period (~40 days) during which larvae (glochidia) can move upstream with
 the aid of host fish. We hypothesized that water-mediated dispersal would
 overwhelm upstream dispersal via host fish, and therefore, that upstream
 subpopulations play a critical role as immigrant sources. To test this
 hypothesis, we examined the effects of both up- and downstream immigrant
 sources on the size of target subpopulations in the Shubuto River system,
 Hokkaido, Japan. We found that target subpopulation size was dependent on
 the upstream distribution range of reproductive subpopulations and the
 number of upstream tributaries, which are proxies for the number of
 potential immigrants moving downstream. In contrast, little influence was
 observed of downstream immigrant sources (proximity to downstream
 reproductive subpopulations). These results were consistent even after
 accounting for local environments and stream size. Our finding suggests
 that upstream subpopulations can be disproportionately important as
 immigrant sources when dispersal is strongly asymmetric.

title: Data from: Environmental change mediates mate choice for an extended phenotype, but not for mate quality

description: Sexual cues, including extended phenotypes, are expected to be reliable
 indicators of male genetic quality and/or provide information on parental
 quality. However, the reliability of these cues may be dependent on
 stability of the environment, with heterogeneity affecting how selection
 acts on such traits. Here we test how environmental change mediates mate
 choice for multiple sexual traits, including an extended phenotype – the
 structure of male-built nests – in stickleback fish. First, we manipulated
 the dissolved oxygen (DO) content of water to create high or low DO
 environments in which male fish built nests. Then we recorded the mate
 choice of females encountering these males (and their nests), under either
 the same or reversed DO conditions. Males in high DO environments built
 more compact nests than those in low DO conditions and males adjusted
 their nest structure in response to changing conditions. Female mate
 choice for extended phenotype (male nests) was environmentally-dependent
 (females chose more compact nests in high DO conditions), while female
 choice for male phenotype was not (females chose large, vigorous males
 regardless of DO level). Examining mate choice in this dynamic context
 suggests that females evaluate the reliability of multiple sexual cues,
 taking into account environmental heterogeneity.

title: Data from: The socially mediated recovery of a fearful fish paired with periodically replaced calm models

description: Social learning is an important mechanism for acquiring knowledge about
 environmental risk. However, little work has explored the learning of
 safety and how such learning outcomes are shaped by the social
 environment. Here, we exposed minnows, Pimephales promelas, to a high-risk
 environment to induce behavioral responses associated with fear (e.g.,
 neophobia). We then used the presence of calm conspecific models (low-risk
 individuals) to weaken these responses. When observers (individuals from
 the high-risk environment) and models were paired consistently in a
 one-on-one setting, the observers showed no recovery (i.e., no weakening
 of the fear responses), and instead the models indirectly acquired those
 responses (i.e., a socially-transmitted state of fear). However, observers
 paired with models that were periodically replaced with new calm models
 showed a significant recovery, and each new model showed diminished
 socially-transmitted fear. We argue that our understanding of
 predation-related fear and social information transfer can prove fruitful
 in understanding problems with fear and stress across animal taxa,
 including among humans who experience post-traumatic stress and secondary
 trauma. Our findings indicate that the periodic replacement of models can
 promote fear recovery in observers and reduce socially-transmitted fear in
 models.

title: Data from: Transcriptome-derived tetranucleotide microsatellites and their associated genes from the giant panda (Ailuropoda melanoleuca)

description: Recently, an increasing number of microsatellites or Simple Sequence
 Repeats (SSRs) have been found and characterized from transcriptome. Such
 SSRs can be employed as putative functional markers to easily tag
 corresponding genes, which play an important role in biomedical studies
 and genetic analysis. However, the transcriptome-derived SSRs for giant
 panda (Ailuropoda melanoleuca) are not yet available. In the present work,
 we identified and characterized 20 tetranucleotide microsatellite loci
 from a transcript database generated from the blood of giant panda.
 Furthermore, we assigned their predicted transcriptome locations: 16 loci
 were assigned to untranslated regions (UTRs) and 4 loci were assigned to
 coding regions (CDSs). Gene identities of 14 transcripts contained
 corresponding microsatellites were determined, which provide useful
 information to study the potential contribution of SSRs to gene regulation
 in giant panda. The polymorphic information content (PIC) values ranged
 from 0.293 to 0.789 with an average of 0.603 for the 16 UTRs-derived SSRs.
 Interestingly, four CDS-derived microsatellites developed in our study
 were also polymorphic, and the instability of these four CDS-derived SSRs
 was further validated by re-genotyping and sequencing. The genes contained
 these four CDS-derived SSRs were embedded with various types of repeat
 motifs. The interaction of all the length-changing SSRs might provide a
 way against coding region frameshift caused by microsatellite instability.
 We hope these newly gene-associated biomarkers would pave the way for
 genetic and biomedical studies for giant panda in the future. In sum, this
 set of transcriptome-derived markers complements the genetic resources
 available for giant panda.

title: Data from: The influence of balanced and imbalanced resource supply on biodiversity-functioning relationship across ecosystems

description: Numerous studies show that increasing species richness leads to higher
 ecosystem productivity. This effect is often attributed to more efficient
 portioning of multiple resources in communities with higher numbers of
 competing species, indicating the role of resource supply and
 stoichiometry for biodiversity–ecosystem functioning relationships. Here,
 we merged theory on ecological stoichiometry with a framework of
 biodiversity–ecosystem functioning to understand how resource use
 transfers into primary production. We applied a structural equation model
 to define patterns of diversity–productivity relationships with respect to
 available resources. Meta-analysis was used to summarize the findings
 across ecosystem types ranging from aquatic ecosystems to grasslands and
 forests. As hypothesized, resource supply increased realized productivity
 and richness, but we found significant differences between ecosystems and
 study types. Increased richness was associated with increased
 productivity, although this effect was not seen in experiments. More even
 communities had lower productivity, indicating that biomass production is
 often maintained by a few dominant species, and reduced dominance
 generally reduced ecosystem productivity. This synthesis, which integrates
 observational and experimental studies in a variety of ecosystems and
 geographical regions, exposes common patterns and differences in
 biodiversity–functioning relationships, and increases the mechanistic
 understanding of changes in ecosystems productivity.

title: Data from: A new Griesbachian-Dienerian (Induan, Early Triassic) ammonoid fauna from Gujiao, South China

description: Bed-by-bed sampling of the lower portion of the Daye Formation at Gujiao,
 Guizhou Province, South China, yielded new Griesbachian–Dienerian (Induan,
 Early Triassic) ammonoid faunas showing a new regional Induan ammonoid
 succession. This biostratigraphic scheme includes in chronological order
 the late Griesbachian Ophiceras medium and Jieshaniceras guizhouense beds,
 and the middle Dienerian Ambites radiatus bed. The latter is recognized
 for the first time as a separate biozone in South China. Eight genera and
 13 species are identified, including one new species, Mullericeras
 gujiaoense n. sp. The new data show that a relatively high level of
 ammonoid taxonomic richness occurred rather rapidly after the
 Permian/Triassic mass extinction in the late Griesbachian, echoing similar
 observations in other basins, such as in the Northern Indian Margin.

title: Data from: Anti-diuretic activity of a CAPA neuropeptide can compromise Drosophila chill tolerance

description: For insects, chilling injuries that occur in the absence of freezing are
 often related to a systemic loss of ion and water balance that leads to
 extracellular hyperkalemia, cell depolarization, and the triggering of
 apoptotic signalling cascades. The ability of insect ionoregulatory organs
 (e.g. the Malpighian tubules) to maintain ion balance in the cold has been
 linked to improved chill tolerance, and many neuroendocrine factors are
 known to influence ion transport rates of these organs. Injection of
 micromolar doses of CAPA (an insect neuropeptide) have been previously
 demonstrated to improve Drosophila cold tolerance, but the mechanisms
 through which it impacts chill tolerance are unclear, and low doses of
 CAPA have been previously demonstrated to cause anti-diuresis in insects,
 including dipterans. Here, we provide evidence that low (fM) and high (uM)
 doses of CAPA impair and improve chill tolerance, respectively, via two
 different effects on Malpighian tubule ion and water transport. While low
 doses of CAPA are anti-diuretic, reduce tubule K+ clearance rates and
 reduce chill tolerance, high doses facilitate K+ clearance from the
 haemolymph and increase chill tolerance. By quantifying CAPA peptide
 levels in the central nervous system, we estimated the maximum achievable
 hormonal titres of CAPA, and found further evidence that CAPA may function
 as an anti-diuretic peptide in Drosophila. We provide the first evidence
 of a neuropeptide that can negatively affect cold tolerance in an insect,
 and further evidence of CAPA functioning as an anti-diuretic peptide in
 this ubiquitous insect model.

title: Data from: Comparison of chemical composition in the buds of Aralia elata from different geographical origins of China

description: Aralia elata buds contain many nutrients and have a pleasant taste with
 unique flavor. Previous studies mainly focused on triterpene saponins in
 the root bark of this species, but little information existed concerning
 other chemical components, especially in the buds. To better understand
 the nutritional value of Aralia elata, we compared total flavonoids, total
 saponins, phenolic compounds and mineral elements contents in the buds of
 Aralia elata collected from eight different geographical regions (S1:
 Benxi; S2: Linjiang; S3: Pingwu; S4: Enshi; S5: Changbaishan; S6:
 Shangzhi; S7: Xiaoxinganling and S8: Harbin) in China. The results showed
 that the basic composition in the buds presented a wide variation noticed
 by ash (8.76 to 10.35%), crude fiber (5.38 to 11.07%), polysaccharides
 (33.85 to 46.79 mg/g), total flavonoid content (4.06 to 48.63 mg/g) and
 total saponins (13.62 to 27.85 mg/g). UPLC combined with LC-MS/MS method
 was used for the phenolic compounds analysis, and eleven phenolic
 compounds were identified and quantified in the 8 samples. The total
 phenolic content in Enshi (S4) was significantly higher than others, and
 quercetin was the predominant phenolic compound in this sample. We used
 ICP-OES to identify and quantify nine mineral elements in the buds. The Fe
 and Cu contents in S5 were much higher than that of others. We got maximum
 Mg, Mn, Co and Ni contents in S4, and found rich Zn content in S7.
 Moreover, the maximum estimated quantity of Ca and Sr contents were found
 in S8. This study indicated that the chemical composition in the buds of
 Aralia elata was obviously affected by geographical origin. Our results
 provided an essential theoretical basis on quality evaluation of Aralia
 elata buds in food production field.
