title: Data from: Molecular field analysis of trophic relationships in soil-dwelling invertebrates to identify mercury, lead and cadmium transmission through forest ecosystems

description: Contamination pathways in complex food chains in soil ecosystems can be
 difficult to elucidate. Molecular analysis of predator gut content can,
 however, rapidly reveal previously unidentified trophic interactions
 between invertebrates and thereby uncover pathways of pollutant spread.
 Here we measured concentrations of the toxic metals lead, cadmium and
 mercury in carabid beetle predators and their prey. Invertebrates were
 sampled at one control and four heavy metal polluted sites in order to
 reveal the impact of diet composition and seasonal variation in prey
 availability on metal burden in carabids and metal transfer pathways
 through forest ecosystems. This is the first report, to our knowledge, of
 carabid diet composition based on PCR analysis of gut contents at the
 forest community level, rather than in cultivated fields. Extensive
 screening using group- and species-specific primers revealed that carabids
 ate primarily earthworms and slugs, as well as smaller numbers of woodlice
 and springtails. Metal concentrations in carabids correlated with seasonal
 changes in diet. Mercury accumulated in beetle predators more than in
 their slug prey. Since earthworms, slugs and carabid beetles are the major
 prey of many birds and mammals, prey-predator transfer and associated
 toxicity are major risks at mercury-contaminated sites. Carabids may be
 useful bioindicators for assessing the impact of pollutants on soil
 ecosystems, as long as species and seasonal factors are taken into
 account.

title: Data from: Fruiting strategies of perennial plants: a resource budget model to couple mast seeding to pollination efficiency and resource allocation strategies

description: Masting, a breeding strategy common in perennial plants, is defined by
 seed production that is highly variable over years and synchronized at the
 population level. Resource budget models (RBMs) proposed that masting
 relies on two processes: (i) the depletion of plant reserves following
 high fruiting levels, which leads to marked temporal fluctuations in
 fruiting; and (ii) outcross pollination that synchronizes seed crops among
 neighboring trees. We revisited the RBM approach to examine the extent to
 which masting could be impacted by the degree of pollination efficiency,
 by taking into account various logistic relationships between pollination
 success and pollen availability. To link masting to other reproductive
 traits, we split the reserve depletion coefficient into three biological
 parameters related to resource allocation strategies for flowering and
 fruiting. While outcross pollination is considered to be the key mechanism
 that synchronizes fruiting in RBMs, our model counterintuitively showed
 that intense masting should arise under low-efficiency pollination. When
 pollination is very efficient, medium-level masting may occur, provided
 that the costs of female flowering (relative to pollen production) and of
 fruiting (maximum fruit set and fruit size) are both very high. Our work
 highlights the powerful framework of RBMs, which include explicit
 biological parameters, to link fruiting dynamics to various reproductive
 traits and to provide new insights into the reproductive strategies of
 perennial plants.

title: Data from: Parasite genetic distance and local adaptation in coevolving bacteria-bacteriophage populations

description: Antagonistic coevolution between hosts and parasites can lead to local
 adaptation (LA), such that parasite fitness is greatest in sympatric hosts
 (or vice versa). The magnitude of LA typically increases with geographic
 distance, which is assumed to be because genetic (and hence phenotypic)
 distance increases with geographic distance. Here we explicitly test the
 relationships between parasite genetic and phenotypic distance and LA
 using isolates of coevolved viral parasites (lytic bacteriophage ϕ2) and
 the host bacterium Pseudomonas fluorescens SBW25. We find positive
 relationships between parasite genotype and infectivity phenotype, but the
 strength of the relationship was greater when infectivity was defined by
 the identity of hosts that could be infected rather than the actual number
 of hosts infected (host range), and when measurements were compared within
 rather than among populations. Crucially, we find a monotonic relationship
 between LA and genetic distance across phage isolates from different
 populations, although in contrast to many geographic studies, parasite LA
 decreased with genetic distance. These results can be explained by the
 fact that bacteria can rapidly adapt to phage infectivity mutations, but
 that evolved resistance has a degree of specificity to the local phage
 population. Our results show that antagonistic coevolution alone can
 result in predictable links between genetic distance and host-parasite
 local adaptation.

title: Data from: Constrasting global genetic patterns in two biologically similar, widespread and invasive Ciona species (Tunicata, Ascidiacea)

description: Human-mediated dispersal interplays with natural processes and complicates
 understanding of the biogeographical history of species. This is
 exemplified by two invasive tunicates, Ciona robusta (formerly Ciona
 intestinalis type A) and C. intestinalis (formerly Ciona intestinalis type
 B), globally distributed and sympatric in Europe. By gathering new
 mitochondrial sequences that were merged with published datasets, we
 analysed genetic patterns in different regions, with a focus on 1) their
 sympatric range and 2) allopatric populations in N and S America and
 southern Europe. In the sympatric range, the two species display
 contrasting genetic diversity patterns, with low polymorphism in C.
 robusta supporting the prevalent view of its recent introduction. In the E
 Pacific, several genetic traits support the non-native status of C.
 robusta. However, in the NE Pacific, this appraisal requires a complex
 scenario of introduction and should be further examined supported by
 extensive sampling efforts in the NW Pacific (putative native range). For
 C. intestinalis, Bayesian analysis suggested a natural amphi-North
 Atlantic distribution, casting doubt on its non-native status in the NW
 Atlantic. This study shows that both natural and human-mediated dispersal
 have influenced genetic patterns at broad scales; this interaction lessens
 our ability to confidently ascertain native vs. non-native status of
 populations, particularly of those species that are globally distributed.

title: Data from: Love the one you're with: proximity determines paternity success in the barnacle Tetraclita rubescens

description: A species’ mating system sets limits on the strength of sexual selection.
 Sexual selection is widespread in dioecious species, but is less well
 documented in hermaphrodites, and may be less important. We used four
 highly polymorphic microsatellite markers to assign paternity to broods of
 the hermaphroditic eastern Pacific volcano barnacle Tetraclita rubescens.
 These data were used to describe the species’ mating system and to examine
 factors affecting male reproductive success. Tetraclita can sire broods
 over distances of 11.2 cm, but proximity to the sperm recipient had a
 highly significant effect on the probability of siring success. There was
 no effect of body size or the mass of male reproductive tissues on siring
 success. Broods showed relatively low frequencies of multiple paternity;
 even at high densities, 75% of broods had only one father. High
 frequencies of single-paternity broods imply either that this species does
 not compete via sperm displacement, or that sperm displacement is
 extremely effective, potentially explaining the lack of a positive
 relationship between male investment and paternity. In addition, there was
 low variance in siring success among individuals, suggesting a lack of
 strong sexual selection on male traits. Low variance among sires and the
 strong effect of proximity are likely driven by the unusual biology of a
 sessile copulating species.

title: Data from: Prevalence, associated factors, awareness, treatment, and control of hypertension: findings from a cross sectional study conducted as a part of a community based intervention trial in Surkhet, Mid-western region of Nepal

description: Background Hypertension is one of the leading public health problems
 globally. About half of the deaths from cardiovascular diseases were
 attributed to hypertension in 2008. Reduction of blood pressure to normal
 range is one of the major challenges in preventing complications and
 future burden of cardiovascular diseases. Therefore, this study aims to
 determine prevalence, awareness, treatment and control of hypertension and
 its associated factors in Nepal. Methods This was a community based
 cross-sectional study conducted as a part of a community based
 intervention trial in Birendranagar Municipality of Surkhet district
 located at the Mid-western region of Nepal. We enrolled 1159 subjects aged
 30 years and above. Out of 12 wards (administrative unit), four wards were
 selected randomly. Three hundred participants were recruited from each
 selected ward. Trained enumerator collected socio-demographic,
 anthropometric, and clinical data using standard STEPS questionnaires.
 Results Out of all participants, women were 71% and mean age was 47±12.6
 years. The overall prevalence of hypertension was 38.9% (95% CI: 36–41.7)
 while age and sex adjusted prevalence was 40.6%. The hypertension was
 present in 48.1% (95% CI: 45.2–50.9) of men and 35.2% (95% CI: 32.4–37.9)]
 of women. Male gender (OR = 1.49), older age (OR = 1.04 per year), Dalit
 caste (OR = 1.71), past history of cigarettes smoking (OR = 2.78), current
 alcohol consumption (OR = 1.75), and raised body mass index (OR = 1.17 per
 unit) were identified as significant factors associated with hypertension.
 Of total hypertensive respondents, 53.4% (95% CI: 48.7–58) were aware, 29%
 (95% CI: 24.8–33.1) were receiving treatment for high blood pressure, and
 8.2% (95% CI: 5.6–10.7) had controlled blood pressure. The awareness,
 treatment, and control status were worse in younger participants.
 Conclusions The study revealed high prevalence with low awareness,
 treatment, and control of hypertension in Nepal. Gender, age, ethnicity,
 smoking, drinking alcohol, and body mass index were associated with
 hypertension. Immediate public health and individual measures are
 warranted to reduce future burden of cardiovascular diseases.

title: Data from: Song playback increases songbird density near low to moderate use roads

description: Many songbird species avoid roads. Although acoustic masking, vehicle
 collision, and edge effects are likely culprits, spatial avoidance also
 occurs along low use roads and at locations distant from the pavement.
 Neophobia may be one factor contributing to avoidance in these regions. In
 this case, playback of bird song, generally a signal of high-quality
 habitat, may reduce avoidance and increase territory establishment. We
 investigated whether playback of song from 6 migratory species increased
 territory establishment along low to moderate use roads in a community of
 songbird species. We determined whether the intensity and regularity of
 anthropogenic noise altered the pattern of response, and whether
 particular life-history traits predicted which species were responsive to
 playback. Territory density was significantly higher where song playback
 was present. Species-specific responses were variable, with 11 species
 increasing territory density by &gt;30% at playback sites and 6
 species decreasing in density. Noise level did not significantly impact
 establishment. Foraging behavior, habitat, and song frequency predicted
 which species were most responsive to playback. These results are similar
 to a companion study conducted near forest edges that did not contain
 roads, and suggests that song playback may be a viable method for
 increasing songbird use of near road habitats. Although additional work is
 needed to understand the variable responses of particular species and to
 address vital issues, such as the reproductive success of lured birds,
 this study highlights a behavioral management technique that may have
 significant conservation implications along the vast worldwide network of
 roads.

title: Data from: First satellite tracks of South Atlantic sea turtle ‘lost years’: seasonal variation in trans-equatorial movement

description: In the South Atlantic Ocean, few data exist regarding the dispersal of
 young oceanic sea turtles. We characterized the movements of
 laboratory-reared yearling loggerhead turtles from Brazilian rookeries
 using novel telemetry techniques, testing for differences in dispersal
 during different periods of the sea turtle hatching season that correspond
 to seasonal changes in ocean currents. Oceanographic drifters deployed
 alongside satellite-tagged turtles allowed us to explore the mechanisms of
 dispersal (passive drift or active swimming). Early in the hatching season
 turtles transited south with strong southward currents. Late in the
 hatching season, when currents flowed in the opposite direction, turtles
 uniformly moved northwards across the Equator. However, the movement of
 individuals differed from what was predicted by surface currents alone.
 Swimming velocity inferred from track data and an ocean circulation model
 strongly suggest that turtles' swimming plays a role in maintaining
 their position within frontal zones seaward of the continental shelf. The
 long nesting season of adults and behaviour of post-hatchlings exposes
 young turtles to seasonally varying ocean conditions that lead some
 individuals further into the South Atlantic and others into the Northern
 Hemisphere. Such migratory route diversity may ultimately buffer the
 population against environmental changes or anthropologic threats,
 fostering population resiliency.

title: Data from: Systematic deviations from linear size spectra of lake fish communities are correlated with predator-prey interactions and lake-use intensity

description: Size structure of organisms at logarithmic scale (i.e. size spectrum) can
 often be described by a linear function with a negative slope; however,
 substantial deviations from linearity have often been found in natural
 systems. Theoretical studies suggest that greater nonlinearity in
 community size spectrum is associated with high predator-prey size ratios
 but low predator-prey abundance ratios; however, empirical evaluation of
 the effects of predator-prey interactions on nonlinear structures remains
 scarce. Here, we aim to empirically explore the pattern of the
 size-specific residuals (i.e. deviations from the linear regression
 between the logarithmic fish abundance and the logarithmic mean fish size)
 by using size spectra of fish communities in 74 German lakes. We found
 that nonlinearity was strong in lakes with high predator-prey abundance
 ratios but at low predator-prey size ratios. More specifically, our
 results suggest that only large predators, even if occurring in low
 abundances, can control the density of prey fishes in a broad range of
 size classes in a community and thus promote linearity in the size
 spectrum. In turn, the lack of large predator fishes may cause high
 abundances of fish in intermediate size classes, resulting in nonlinear
 size spectra in these lakes. Moreover, these lakes were characterized by a
 more intense human use including high fishing pressure and high total
 phosphorus concentrations, which have negative impacts on the abundance of
 large, predatory fish. Our findings indicate that nonlinear size spectra
 may reflect dynamical processes potentially caused by predator-prey
 interactions. This opens a new perspective in the research on size
 spectrum, and can be relevant to further quantify the efficiency of energy
 transfer in aquatic food webs.

title: Data from: CO2 alters community composition and response to nutrient enrichment of freshwater phytoplankton

description: Nutrients can limit the productivity of ecosystems and control the
 composition of the communities of organisms that inhabit them. Humans are
 causing atmospheric CO2 concentrations to reach levels higher than those
 of the past millions of years while at the same time propagating
 eutrophication through the addition of nutrients to lakes and rivers. We
 studied the effect of elevated CO2 concentrations, nutrient addition and
 their interaction in a series of freshwater mesocosm experiments using a
 factorial design. Our results highlight the important role of CO2 in
 shaping phytoplankton communities and their response to nutrient addition.
 We found that CO2 greatly magnified the increase in phytoplankton growth
 caused by the increased availability of nutrients. Elevated CO2 also
 caused changes in phytoplankton community composition. As predicted from
 physiology and laboratory experiments, the taxonomic group that was most
 limited by current day CO2 concentrations, chlorophytes, increased in
 relative frequency at elevated CO2. This predictable change in community
 composition with changes in CO2 is not altered by changes in the
 availability of other nutrients.
