title: Data from: Tropical ancient DNA from bulk archaeological fish bone reveals the subsistence practices of a historic coastal community in southwest Madagascar

description: Taxonomic identification of archaeological fish bones provides important
 insights into the subsistence practices of ancient coastal peoples.
 However, it can be difficult to execute robust morphological
 identification of fish bones from species-rich fossil assemblages,
 especially from post-cranial material with few distinguishing features.
 Fragmentation, weathering and burning further impede taxonomic
 identification, resulting in large numbers of unidentifiable bones from
 archaeological sites. This limitation can be somewhat mitigated by taking
 an ancient DNA (aDNA) bulk-bone metabarcoding (BBM) approach to faunal
 identification, where DNA from non-diagnostic bone fragments is extracted
 and sequenced in parallel. However, a large proportion of fishing
 communities (both past and present) live in tropical regions that have
 sub-optimal conditions for long-term aDNA preservation. To date, the BBM
 method has never been applied to fish bones before, or to fossils
 excavated from an exposed context within a tropical climate. Here, we
 demonstrate that morphologically indistinct bulk fish bone from the
 tropics can be identified by sequencing aDNA extracted from 100 to 300 ya
 archaeological midden material in southwest Madagascar. Despite the biases
 of the approach, we rapidly obtained family, genus, and species-level
 assemblage information, and used this to describe a subset of the
 ichthyofauna exploited by an 18th century fishing community. We identified
 23 families of fish, including benthic, pelagic, and coral-dwelling
 fishes, suggesting a reliance on a variety of marine and brackish
 habitats. When possible, BBM should be used alongside osteological
 approaches to address the limitations of both; however, this study
 highlights how genetic methods can nevertheless be a valuable tool for
 helping resolve faunal assemblages when morphological identification is
 hindered by taphonomic processes, lack of adequate comparative
 collections, and time constraints, and can provide a temporal perspective
 on fish biodiversity in the context of accelerated exploitation of the
 marine environment.

title: Data from: Enhanced decomposition and nitrogen mineralisation sustain rapid growth of Eucalyptus regnans after wildfire

description: Eucalyptus regnans grows rapidly from seed after wildfires, out-competing
 other species, thereby forming pure stands of mature forests that rank
 amongst the world's most carbon dense. By global standards, these
 forests grow on infertile soils. It is unclear how E. regnans is able to
 obtain large amounts nitrogen (N) from these infertile soils to support
 its rapid growth after fire. We measured carbon (C) and N stored in plant
 biomass and photosynthetic rates of E. regnans 2 years after a wildfire
 and examined whether E. regnans stimulated its own N supply through
 root-induced increases in microbial decomposition and N mineralization. We
 compared microbial biomass, gross N mineralization rates and soil C in
 trenched and rooted plots. Photosynthetic rates of E. regnans seedlings
 were high and comparable to photosynthetic rates observed in fertilized
 crops. Presence of roots of E. regnans and allied microflora enhanced
 gross N mineralization more than fivefold compared to soil without roots
 present. Soil microbial biomass was more than doubled by root presence.
 The soil N pulse caused by the fire and N mineralization rates in the
 absence of roots were too small to account for the large amount of N
 stored in E. regnans 2 years after the fire. Our results suggest that E.
 regnans facilitated its rapid growth by enhancing microbial activity and N
 mineralization. This enhanced microbial activity also contributed to a
 substantial loss of soil C (˜62% of carbon gained in plant biomass was
 concurrently lost from soil). Synthesis. At the ecosystem scale, the
 synergistic effects of plant growth and soil N mineralization need to be
 carefully assessed against costs to soil C for forests regenerating after
 disturbance.

title: Data from: Positive correlations between pre- and post-copulatory sexual traits in warblers

description: Theoretical models predict that investment in pre-copulatory and
 post-copulatory sexually selected traits should trade-off. At the
 macroevolutionary scale, the majority of studies to date have focused on
 male weaponry as the target of pre-copulatory sexual selection, but the
 trade-off should equally apply to traits used to attract females, such as
 bird song and plumage. We studied the Old World leaf warblers
 (Phylloscopidae), a group of socially monogamous songbirds that experience
 relatively high levels of sperm competition. We examined the relationships
 between song duration and number of elements in the song with sperm length
 across 21 species, and between the same song variables and combined testes
 mass in a subset of these species (n=10). Across species, these song
 variables and testes mass/sperm length were generally positively
 correlated, albeit not statistically significantly so or with borderline
 significance. In contrast to theory, we found no evidence for negative
 associations between pre- and post-copulatory traits. We argue that this
 is a consequence of males of some species investing more into overall
 fertilization success (i.e. the sum of pre- and post-copulatory sexual
 selection) than males of other species, and high fertilization success is
 achieved through investment into both mate attraction and sperm
 competition.

title: Data from: Key players and hierarchical organization of prairie dog social networks

description: The use of social network theory in evaluating animal social groups has
 gained traction in recent years. Despite the utility of social network
 analysis in describing attributes of social groups, it remains unclear how
 comparable this approach is to traditional behavioral observational
 studies. Using data on Gunnison’s prairie dog (Cynomys gunnisoni) social
 interactions we describe social networks from three populations. We then
 compare those social networks to groups identified by traditional
 behavioral approaches and explore whether individuals group together based
 on similarities. The social network social groups identified by social
 network analysis were consistent with those identified by more traditional
 behavioral approaches. However, fine-grained social sub-structuring was
 revealed only with social network analysis. We found variation in the
 patterns of interactions among prairie dog social groups that was largely
 independent of the behavioral attributes or genetics of the individuals
 within those groups. We detected that some social groups include
 disproportionately well-connected individuals acting as hubs or bridges.
 This study contributes to a growing body of evidence that social networks
 analysis is a robust and efficient tool for examining social dynamics.

title: Data from: Solar-powered flow-through system for aquatic field studies

description: 1 Laboratory-based research provides great control over individual
 experimental replicates, but lacks the ecological realism of field work.
 Therefore, results from lab-based work may not reflect natural processes.
 Field-based studies have the advantage of ecological realism but often
 lack control over environmental variables and have low rates of
 within-experiment replication and as a result can have low statistical
 power to detect effects. 2 Here, we present a method for creating a
 standardized system for experimental replicates in the field using
 solar-powered water pumps to run a modified zebrafish aquatic habitat
 system with recirculating water in situ. In our pilot study we used this
 apparatus to test the effects of naturally-occurring parasites on the
 behavior of individual fathead minnows, but this experimental set-up has
 potential for broad application to field-based research in aquatic
 ecology. 3 We constructed a simple frame from conventional 2” x 4” lumber
 to support rows of 1-L tanks in the littoral zone of a small lake. Lake
 water is pumped to an overhead manifold from a PVC pipe drilled with one
 hole over each tank. A short length of airline tubing directs the water
 flow into each individual tank. Water entering each tank passes through
 the manufacturer's grate at the rear of each tank and returns to the
 lake. We stocked one fish per tank, therefore the lack of water flow
 during the night did not cause duress or mortality. 4 This system allowed
 control over individual test subjects while housing them in semi-natural
 conditions with a steady supply of lake water at a field site far removed
 from any source of electricity.

title: Data from: Neural signatures for sustaining object representations attributed to others in preverbal human infants

description: A major feat of social beings is to encode what their conspecifics see,
 know or believe. While various nonhuman animals show precursors of these
 abilities, humans perform uniquely sophisticated inferences about other
 people’s mental states. However, it is still unclear how these possibly
 human-specific capacities develop and whether preverbal infants, similarly
 to adults form representations of other agents’ mental states,
 specifically metarepresentations. We explored the neuro-cognitive bases of
 8-month-olds’ ability to encode the world from another person’s
 perspective, using gamma-band EEG activity over the temporal lobes, an
 established neural signature for sustained object representation after
 occlusion. We observed such gamma-band activity when an object was
 occluded from the infants’ perspective, as well as when it was occluded
 only from the other person (Experiment 1), and also when subsequently the
 object disappeared but the person falsely believed the object to be
 present (Experiment 2). These findings suggest that the cognitive systems
 involved in representing the world from infants’ own perspective are also
 recruited for encoding others’ beliefs. Such results point to an early
 developing, powerful apparatus suitable to deal with multiple concurrent
 representations; and suggest that infants can have a metarepresentational
 understanding of other minds even before the onset of language.

title: Data from: Taxonomic and phylogenetic diversity of vascular plants at Ma’anling volcano urban park in tropical Haikou, China: Reponses to soil properties

description: Anthropogenic processes and socio-economic factors play important roles in
 shaping plant diversity in urban parks. To investigate how plant diversity
 of Ma’ anling urban volcano park in Hainan Province, China respond to
 these factors, we carried out a field investigation on the taxonomic and
 phylogenetic diversity of vascular plants and soil properties in this
 area. We found 284 species of vascular plants belonging to 88 families and
 241 genera, which included 194 native species, 23 invasive species, 31
 naturalized species, 40 cultivars, and 4 rare / endangered plant species.
 Tree composition and richness significantly varied between different
 vegetation formations (plantation, secondary forest, and abandoned land).
 Plant species richness and community composition were significantly
 affected by elevation (El), soil water content (WC), total soil nitrogen
 (TN) and soil organic matter (SOM). There were significant diversity
 differences between plantations and abandoned lands, but not between the
 plantations and secondary forests. The flora in the study site was
 tropical in nature, characterized by pantropic distributions. Compared to
 adjacent areas, floristic composition in the study site was most similar
 to that of Guangdong, followed by that of Vietnam. Our study revealed the
 diversity patterns of volcanic plants and provided the basis for future
 planning of plant conservation, such as preserving plant species,
 maintaining plant habitats, and coordinating plant management in this
 region.

title: Data from: Negative effects of vertebrate on invertebrate herbivores mediated by enhanced plant nitrogen content

description: 1. Classic theory holds that the main interaction within the herbivore
 guild is competition, based on research focused on co-occurring,
 similarly-sized species that reduce the quantity of shared plant
 resources. However, plant quality may also be crucial in mediating
 herbivore interspecific interactions. This is especially true when
 competition occurs between distantly-related herbivore species, given that
 small terrestrial herbivores (e.g. insect herbivores) appear to be more
 sensitive to alterations of plant quality than plant quantity. 2. In this
 study, we first tested in the field whether large vertebrate herbivores
 (cattle Bos taurus) exerted a negative effect on smaller insect herbivores
 (grasshopper Euchorthippus unicolor) through their overlapping foraging
 preferences for a dominant grass Leymus chinensis. We measured changes in
 grass quantity, grass quality, and microclimatic conditions in response to
 vertebrate grazing and conducted additional manipulative studies in the
 field and the laboratory to identify potential mechanisms underlying the
 interaction. 3. Our results showed that grazing by large herbivores caused
 a significant decline in grasshopper population density and individual
 performance (survival, size and weight of both female and male E.
 unicolor), despite a 38% increase in grass nitrogen (N) content in grazed
 plots. Experiments manipulating N levels of L. chinensis in the field and
 the laboratory confirmed that enriching plant N had a negative effect on
 grasshopper individual performance and population size. Therefore,
 enhanced quality (N content) of plant resources appears to be an important
 driver in mediating the negative effect of vertebrate grazing on
 grasshoppers. 4. Synthesis. We document that phylogenetic relatedness and
 trait similarity can be poor predictors of interaction strength in some
 cases, since distantly related herbivores of disparate size can interact
 indirectly via changes in plant quality. Counter-intuitively, the observed
 negative effect of cattle on grasshoppers was mediated, at least in part,
 by an increase in plant quality in cattle grazed areas. The implication is
 that light to moderate grazing, a common management strategy, may
 contribute to suppression of grasshoppers in the Eurasian steppe grassland
 system by altering plant nutrient supplies.

title: Data from: Whence the beardogs? Reappraisal of the Middle to Late Eocene ‘Miacis’ from Texas, USA, and the origin of Amphicyonidae (Mammalia, Carnivora)

description: The Middle to Late Eocene sediments of Texas have yielded a wealth of
 fossil material that offers a rare window on a diverse and highly endemic
 mammalian fauna from that time in the southern part of North America.
 These faunal data are particularly significant because the narrative of
 mammalian evolution in the Paleogene of North America has traditionally
 been dominated by taxa that are known from higher latitudes, primarily in
 the Rocky Mountain and northern Great Plains regions. Here we report on
 the affinities of two peculiar carnivoraforms from the Chambers Tuff of
 Trans-Pecos, Texas, that were first described 30 years ago as Miacis
 cognitus and M. australis. Re-examination of previously described
 specimens and their inclusion in a cladistic analysis revealed the two
 taxa to be diminutive basal amphicyonids; as such, they are assigned to
 new genera Gustafsonia and Angelarctocyon, respectively. These two taxa
 fill in some of the morphological gaps between the earliest-known
 amphicyonid genus, Daphoenus, and other Middle-Eocene carnivoraforms, and
 lend additional support for a basal caniform position of the beardogs
 outside the Canoidea. The amphicyonid lineage had evidently given rise to
 at least five rather distinct forms by the end of the Middle Eocene. Their
 precise geographical origin remains uncertain, but it is plausible that
 southern North America served as an important stage for a very early phase
 of amphicyonid radiation.

title: Data from: Gene exchange between two divergent species of the fungal human pathogen, Coccidioides

description: The fungal genus Coccidioides is composed of two species, Coccidioides
 immitis and C. posadasii. These two species are the causal agents of
 coccidioidomycosis, a pulmonary disease also known as valley fever. The
 two species are thought to have shared genetic material due to gene
 exchange in spite of their long divergence. To quantify the magnitude of
 shared ancestry between them, we analyzed the genomes of a population
 sample from each species. Next, we inferred what is the expected size of
 shared haplotypes that might be inherited from the last common ancestor of
 the two species and find a cutoff to find what haplotypes have
 conclusively been exchanged between species. Finally, we precisely
 identified the breakpoints of the haplotypes that have crossed the species
 boundary and measure the allele frequency of each introgression in this
 sample. We find that introgressions are not uniformly distributed across
 the genome. Most, but not all, of the introgressions segregate at low
 frequency. Our results show that divergent species can share alleles, that
 species boundaries can be porous, and highlight the need for a systematic
 exploration of gene exchange in fungal species.

title: Data from: Linking songbird nest predation to seedling density: sugar maple masting as a resource pulse in a forest food web

description: The ecological literature presents considerable evidence for top-down
 forcing on the maintenance of species diversity. Yet, in temperate
 forests, bottom-up forces often exert a strong influence on ecosystem
 functioning. Here, we report on the indirect influence of a pulsed
 resource, sugar maple (Acer saccharum) seed production, on nest survival
 in a migratory songbird. We hypothesized that seed production in year t
 would determine daily nest survival rate in year t + 1 through its effects
 on seed-eating rodents. We used the density of sugar maple seedlings (with
 cotyledons) in year t + 1 as a proxy for seed production in year t and
 predicted that it would be inversely related to songbird nest survival the
 same year. We estimated the density of sugar maple seedlings, eastern
 chipmunk (Tamias striatus) activity, and daily nest survival rate in the
 ovenbird (Seiurus aurocapilla) over four successive years in a northern
 hardwood forest of New Brunswick, Canada. Seedling density varied by two
 orders of magnitude between years, whereas an index of chipmunk activity
 changed by an order of magnitude. Both variables were positively
 correlated and negatively correlated to daily nest survival rate. A
 logistic-exposure model including only seedling density received the
 greatest level of support (lowest AICc). Previous studies have reported
 the effect of sugar maple masting on seed-eating rodent populations, but
 the strong link we report between seedling density and songbird nest
 survival is novel. A nocturnal seed-eating nest predator, deer mouse
 (Peromyscus maniculatus), was not considered in our models, which may
 explain why chipmunk was not the best predictor of daily nest survival
 rate. The trophic linkages we observed are remarkably strong for a
 temperate forest ecosystem and might become more prevalent in northeastern
 North America, at least on calcium-rich soils, with the loss of
 large-diameter beech trees as a result of beech bark disease.

 in four 25 ha plots from 2012 to 2015. Each line corresponds to an
 Ovenbird nest. The number of exposure days was used to calculate the daily
 survival rate of nests. Mean chipmunk detections corresponds to the mean
 number of visual or aural detections recorded in each plot and year (6
 surveys per plot per year). Mean seedling density indicates the mean
 density of newly-emerged sugar maple seedlings (with cotyledons) counted
 in fifty 250 cm^2 quadrats in each plot and year. Treatment refers to
 selection harvesting (30-40% basal area removal) conducted in two of the
 four plots during the winter of 2006-2007.Data_Fiola et
