title: Data from: Enhancement on the electrochemical properties of commercial coconut shell-based activated carbon by H2O dielectric barrier discharge plasma

description: Commercial coconut shell-based activated carbon (CSAC) has low specific
 capacitance and specific capacitance retention owing to its undeveloped
 pore structure and low proportion of heteroatoms. In this study,
 dielectric barrier discharge (DBD) plasma was used to enhance the specific
 capacitance and rate capability of CSAC. H2O was used as excited medium to
 introduce oxygen functional groups. The physicochemical properties of CSAC
 and CSAC modified by H2O plasma (HCSAC) were revealed by automated surface
 area and pore size analysis, Fourier transform infrared spectroscopy
 (FTIR), X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy
 (Raman). Electrochemical workstation was applied to investigate the
 electrochemical properties of CSAC and HCSAC. Obtained results showed that
 plasma modification improved the specific capacitance of CSAC by 64.8%
 (current density, 1 A g-1; electrolyte, 6 M KOH solution) within 100
 seconds. This result is ascribed to the oxygen functional groups
 introduced to the surface of CSAC. It can also improve hydrophilicity and
 wettability of the carbon surface leading to an increase from 76.7% to
 84.6% in specific capacitance retention. Furthermore, H2O plasma
 modification can introduce oxygen functional groups without destroying the
 initial pore structures of CSAC. In summary, we provide a simple, fast,
 environment-friendly modification method to enhance the electrochemical
 properties of CSAC.

title: Data from: Using novel phylogenetic methods to evaluate mammalian mtDNA, including amino acid-invariant sites-LogDet plus site stripping, to detect internal conflicts in the data, with special reference to the positions of hedgehog, armadillo, and elephant

description: We look at the higher-order phylogeny of mammals, analyzing in detail the
 complete mtDNA sequences of over 40 species. We test the support for
 several proposed super-ordinal relationships. To this end, we apply a
 number of recently programmed methods and approaches, plus better
 established methods. New pairwise tests show that there is highly
 significant evidence that amino acid frequencies are changing among nearly
 all the genomes studied when unvaried sites are ignored. LogDet amino acid
 distances, with modifications to take into account invariant sites, are
 combined with bootstrapping and the Neighbor Joining algorithm to account
 for these violations of standard models. To weight the slower evolving
 sites, we exclude the more rapidly evolving sites from the data using
 "site stripping". This leads to changing optimal trees with
 nearly all methods. The bootstrap support for many hypotheses varies
 widely between methods, and few hypotheses can claim unanimous support
 from these data. Rather, we uncover good evidence that many of the earlier
 branching patterns in the placental subtree could be incorrect, and this
 includes the placement of the root. The tRNA genes, for example, favour a
 split between the group hedgehog, rodents and Primates versus all other
 sequenced placentals. Such a grouping is not ruled out by the amino acid
 sequence data. A grouping of all rodents plus rabbit, the old Glires
 hypothesis, is also feasible with stripped amino acid data, while rodent
 monophyly is also common. The elephant sequence allows confident rejection
 of the older taxon Ferungulata (Simpson 1945). In its place, the new taxa
 Scrotifera and Fereuungulata is defined. A new likelihood ratio test is
 used to detect differences between the optimal tree for tRNA versus that
 for amino acids. While not clearly significant as made, there are
 indications the test is tending towards significance with more general
 models of evolution. Individual placement tests suggest alternative
 positions for hedgehog, and the elephant. There are striking congruence
 arguments to support elephant and armadillo together, suggesting a
 superordinal group composed of Xenarthra and African endemic mammals,
 which in turn may be near the root of the placental subtree. Thus, the
 analyses while casting doubt on some recent conclusions, are also
 unveiling some interesting new possibilities.

title: Data from: Differential investment in pre- versus post-copulatory sexual selection reinforces a cross-continental reversal of sexual size dimorphism in Sepsis punctum (Diptera: Sepsidae)

description: Theory predicts that males have a limited amount of resources to invest in
 reproduction, suggesting a trade-off between traits that enhance mate
 acquisition and those enhancing fertilization success. Here we investigate
 the relationship between pre- and post-copulatory investment by comparing
 the mating behavior and reproductive morphology of four European and five
 North American populations of the dung fly Sepsis punctum (Diptera) that
 display a reversal of sexual size dimorphism (SSD). We show that the
 geographic reversal in SSD between the continents (male-biased in Europe,
 female-biased in North America) is accompanied by differential investment
 in pre- versus post-copulatory traits. We find higher re-mating rates in
 European populations, where larger males acquire more matings and
 consequently have evolved relatively larger testes and steeper
 hyper-allometry with body size. American populations, in sharp contrast,
 display much reduced, if any, effect of body size on those traits.
 Instead, North American males demonstrate an increased investment in mate
 acquisition prior to copulation, with more mounting attempts and a
 distinctive abdominal courtship display that is completely absent in
 Europe. When controlling for body size, relative female spermathecal size
 is similar on both continents, so we find no direct evidence for the
 co-evolution of male and female internal reproductive morphology. By
 comparing allopatric populations of the same species that apparently have
 evolved different mating systems and consequently SSD, we thus indirectly
 demonstrate differential investment in pre- vs. post-copulatory mechanisms
 increasing reproductive success.

title: Data from: Sex-specific pathways of parental age effects on offspring lifetime reproductive success in a long-lived seabird

description: The conditions under which individuals are reared vary and sensitivity of
 offspring to such variation is often sex-dependent. Parental age is one
 important natal condition with consequences for aspects of offspring
 fitness, but reports are mostly limited to short-term fitness consequences
 and do not take into account offspring sex. Here we used individual-based
 data from a large colony of a long-lived seabird, the common tern Sterna
 hirundo, to investigate longitudinal long-term fitness consequences of
 parental age in relation to both offspring and parental sex. We found that
 recruited daughters from older mothers suffered from reduced annual
 reproductive success. Recruited sons from older fathers were found to
 suffer from reduced lifespan. Both effects translated to reductions in
 offspring lifetime reproductive success. Besides revealing novel
 sex-specific pathways of trans-generational parental age effects on
 offspring fitness, which inspire studies of potential underlying
 mechanisms, our analyses show that reproductive senescence is only
 observed in the common tern when including trans-generational age effects.
 In general, our study shows that estimates of selective pressures
 underlying the evolution of senescence, as well as processes such as
 age-dependent mate choice and sex allocation, will depend on whether
 causal trans-generational effects exist and are taken into account.

title: Data from: The level of an intracellular antioxidant during development determines the adult phenotype in a bird species: a potential organizer role for glutathione

description: Life-history traits are often involved in trade-offs whose outcome would
 depend on the availability of resources but also on the state of specific
 molecular signals. Early conditions can influence trade-offs and program
 the phenotype throughout the lifetime, with oxidative stress likely
 involved in many taxa. Here we address the potential regulatory role of a
 single intracellular antioxidant in life-history trade-offs. Blood
 glutathione levels were reduced in a large sample of birds (zebra finch
 Taeniopygia guttata) during development using the synthesis inhibitor
 buthionine sulfoximine (BSO). Results revealed several modifications in
 the adult phenotype. BSO-treated nestlings showed lower glutathione and
 plasma antioxidant levels. In adulthood, BSO birds endured greater
 oxidative damage in erythrocytes but stronger expression of a sexual
 signal. Moreover, adult BSO females also showed weaker resistance to
 oxidative stress but were heavier and showed better body condition.
 Results suggest that low glutathione values during growth favor the
 investment in traits that should improve fitness returns, probably in the
 form of early reproduction. Higher oxidative stress in adulthood may be
 endured if this cost is paid later in life. Either the presence of
 specific signaling mechanisms or the indirect effect of increased
 oxidative stress can explain our findings.

title: Data from: Is diversification history of maize influencing selection of soil bacteria by roots?

description: A wide range of plant lines has been propagated by farmers during crop
 selection and dissemination, but consequences of this crop diversification
 on plant-microbe interactions have been neglected. Our hypothesis was that
 crop evolutionary history shaped the way the resulting lines interact with
 soil bacteria in their rhizospheres. Here, the significance of maize
 diversification as a factor influencing selection of soil bacteria by
 seedling roots was assessed by comparing rhizobacterial community
 composition of inbred lines representing the five main genetic groups of
 maize, cultivated in a same European soil. Rhizobacterial community
 composition of 21-day-old seedlings was analyzed using a 16S rRNA
 taxonomic microarray targeting 19 bacterial phyla. Rhizobacterial
 community composition of inbred lines depended on the maize genetic group.
 Differences were largely due to the prevalence of certain
 Betaproteobacteria and especially Burkholderia, as confirmed by
 quantitative PCR and cloning/sequencing. However, these differences in
 bacterial root colonization did not correlate with plant microsatellite
 genetic distances between maize genetic groups or individual lines.
 Therefore, the genetic structure of maize that arose during crop
 diversification (resulting in five main groups), but not the extent of
 maize diversification itself (as determined by maize genetic distances),
 was a significant factor shaping rhizobacterial community composition of
 seedlings.

title: Data from: Patterns and persistence of larval retention and connectivity in a marine fish metapopulation

description: Connectivity, the demographic linking of local populations through the
 dispersal of individuals, is one of the most poorly understood processes
 in population dynamics, yet has profound implications for conservation and
 harvest strategies. For marine species with pelagic larvae, direct
 estimation of connectivity remains logistically challenging and has mostly
 been limited to single snapshots in time. Here, we document seasonal and
 interannual patterns of larval dispersal in a metapopulation of the coral
 reef fish Amphiprion polymnus. A 3-year record of larval trajectories
 within and among nine discrete local populations from an area of
 approximately 35 km was established by determining the natal origin of
 settled juveniles through DNA parentage analysis. We found that spatial
 patterns of both self-recruitment and connectivity were remarkably
 consistent over time, with a low level of self-recruitment at the scale of
 individual sites. Connectivity among sites was common and multidirectional
 in all years and was not significantly influenced by seasonal variability
 of predominant surface current directions. However, approximately 75% of
 the sampled juveniles could not be assigned to parents within the study
 area, indicating high levels of immigrations from sources outside the
 study area. The data support predictions that the magnitude and temporal
 stability of larval connectivity decreases significantly with increasing
 distance between subpopulations, but increases with the size of
 subpopulations. Given the considerable effort needed to directly measure
 larval exchange, the consistent patterns suggest snapshot parentage
 analyses can provide useful dispersal estimates to inform spatial
 management decisions.

title: Data from: Jack of all trades masters novel host plants: positive genetic correlations in specialist and generalist insect herbivores expanding their diets to novel hosts

description: One explanation for the widespread host specialization of insect
 herbivores is the "Jack of all trades-master of none" principle,
 which states that genotypes with high performance on one host will perform
 poorly on other hosts. This principle predicts that cross-host correlation
 in performance of genotypes will be negative. In this study we
 experimentally explored cross-host correlations and performance among
 families in four species (two generalist and two specialist) of leaf
 beetles (Cephaloleia spp.) that are currently expanding their diets from
 native to exotic plants. All four species displayed similar responses in
 body size, developmental rates and mortality rates to experimentally
 controlled diets. When raised on novel hosts, body size of larvae, pupae
 and adults were reduced. Development times were longer and larval
 mortality was higher on novel hosts. Genotype × host plant interactions
 were not detected for most traits. All significant cross-host correlations
 were positive. These results indicate very different ecological and
 evolutionary dynamics than those predicted by the “Jack of all
 trades-master of none” principle.

title: Data from: Phylogenetics, delimitation and historical biogeography of the pantropical tree genus Thespesia (Malvaceae, Gossypieae)

description: Thespesia consists of 16 species of trees and shrubs from Southeast
 Asia–Oceania, Africa and America, the most well known being T. populnea, a
 small tree of tropical coastal areas around the world. Phylogenetic
 relationships in the genus and among its allies in tribe Gossypieae were
 inferred using three plastid and two nuclear regions to ascertain its
 generic delimitation and explore its biogeographical history.
 Maximum-likelihood and Bayesian analyses confirmed that Thespesia is not
 monophyletic and, based on these results, Azanza is reinstated to
 accommodate the two species previously placed in Thespesia section Lampas.
 Dating analyses and ancestral range estimation indicated that Thespesia
 s.s. most likely originated in Southeast Asia–Oceania c. 30 Mya, but
 extant species did not begin to differentiate until the late Miocene. Two
 dispersal events, one into Africa c. 11 Mya and another into America
 (Antilles) c. 9 Mya, gave rise to the African and the Greater Antillean
 endemics, respectively. The two most widespread hydrochorous species, T.
 populnea and T. populneoides, originated in Southeast Asia–Oceania from
 where they spread to other parts of the world. Our analysis also indicated
 a much earlier origin than previously reported for Eumalvoideae and its
 tribes, suggesting that vicariance might have had an important role early
 in the history of these groups.

title: Data from: Early phylogenetic divergence of gynodioecious species warrants the recognition of subseries in Styrax series Valvatae

description: In Styrax (Ericales: Styracaceae), gynodioecy is known or likely in ten
 species. A previous morphological analysis of the genus placed these
 species into a single highly derived clade within S. series Valvatae. In
 contrast, DNA sequence data from the nuclear ribosomal internal
 transcribed spacer (ITS) region yielded two distinct gynodioecious clades
 within the series, one (South American species) as sister to the rest of
 S. series Valvatae, the other (S. obtusifolius only; Cuba) as
 phylogenetically nested within a clade of otherwise hermaphroditic
 species. Here we test these contrasting phylogenetic placements with
 analyses that include the plastid ndhF-rpl32-trnL, trnL-trnF, trnS-trnG,
 and trnV-ndhC genic regions in addition to ITS. Results strongly
 corroborate the phylogenetic positions of the two gynodioecious clades
 based on ITS data alone. Clade-specific ITS-plastid phylogenetic
 discordance provides evidence for hybridization and suggests a pattern of
 reticulate evolution among some of the southern Brazilian species of the
 series. Our results agree with the prior evidence for convergent evolution
 among the gynodioecious species associated with floral reduction. Based on
 our results and long-standing precedent, we re-confer formal taxonomic
 recognition on the South American gynodioecious clade by dividing S.
 series Valvatae into two new subseries, Styrax subseries Latifoli and
 Foveolaria.
