title: Data from: Divergence within and among seaweed siblings (Fucus vesiculosus and F. radicans) in the Baltic Sea

description: Closely related taxa provide significant case studies for understanding
 evolution of new species but may simultaneously challenge species
 identification and definition. In the Baltic Sea, two dominant and
 perennial brown algae share a very recent ancestry. Fucus vesiculosus
 invaded this recently formed postglacial sea 8000 years ago and shortly
 thereafter Fucus radicans diverged from this lineage as an endemic
 species. In the Baltic Sea both species reproduce sexually but also
 recruit fully fertile new individuals by asexual fragmentation. Earlier
 studies have shown local differences in morphology and genetics between
 the two taxa in the northern and western Bothnian Sea, and around the
 island of Saaremaa in Estonia, but geographic patterns seem in conflict
 with a single origin of F. radicans. To investigate the relationship
 between northern and Estonian distributions, we analysed the genetic
 variation using 9 microsatellite loci in populations from eastern Bothnian
 Sea, Archipelago Sea and the Gulf of Finland. These populations are
 located in between earlier studied populations. However, instead of
 bridging the disparate genetic gap between N-W Bothnian Sea and Estonia,
 as expected from a simple isolation-by-distance model, the new populations
 substantially increased overall genetic diversity and showed to be
 strongly divergent from the two earlier analysed regions, showing signs of
 additional distinct populations. Contrasting earlier findings of increased
 asexual recruitment in low salinity in the Bothnian Sea, we found high
 levels of sexual reproduction in some of the Gulf of Finland populations
 that inhabit extremely low salinity. The new data generated in this study
 supports the earlier conclusion of two reproductively isolated but very
 closely related species. However, the new results also add considerable
 genetic and morphological complexity within species. This makes species
 separation at geographic scales more demanding and suggests a need for
 more comprehensive approaches to further disentangle the intriguing
 relationship and history of the Baltic Sea fucoids.

title: Data from: Robotic investigation on effect of stretch reflex and crossed inhibitory response on bipedal hopping

description: To maintain balance during dynamic locomotion, the effects of
 proprioceptive sensory feedback control (e.g. reflexive control) should
 not be ignored because of its simple sensation and fast reaction time.
 Scientists have identified the pathways of reflexes; however, it is
 difficult to investigate their effects during locomotion because
 locomotion is controlled by a complex neural system and current technology
 does not allow us to change the control pathways in living humans. To
 understand these effects, we construct a musculoskeletal bipedal robot,
 which has similar body structure and dynamics to a human. By conducting
 experiments on this robot, we investigate the effects of reflexes (stretch
 reflex and crossed inhibitory response) on the posture during hopping, a
 simple and representative bouncing gait with complex dynamics. Through
 over 300 hopping trials, we confirm that both the stretch reflex and
 crossed response can contribute to reducing the lateral inclination during
 hopping. These reflexive pathways do not use any prior knowledge of the
 dynamic information of the body such as its inclination. Beyond improving
 the understanding of human neural system, this study provides roboticists
 with biomimetic ideas for robot locomotion control.

title: Data from: Prolific fruit output by the invader Bellucia pentamera (Melastomataceae) is enhanced by selective logging disturbance

description: Selective logging in tropical rain forests may promote population growth
 of invasive plants. The ability of invaders to respond, specifically in
 reproductive traits, to increases in resource abundance may allow them to
 increase their presence in the seed rain of recipient communities. The
 invasive pioneer tree Bellucia pentamera (Melastomataceae) is currently
 spreading within Gunung Palung National Park in West Kalimantan,
 Indonesia. The park has also experienced periods of illegal, small-scale,
 selective logging that seem to have facilitated population growth and
 spread of this invader. We first used fruiting frequency as a proxy for
 fruit output to make comparisons between B. pentamera and the native tree
 community of over 200 genera. We then constructed two Generalized Linear
 Autoregressive Moving Average (GLARMA) models using 13 months of phenology
 data to predict both fruiting frequency and crop size of B. pentamera
 under selective logging versus natural treefall disturbance regimes.
 Bellucia pentamera fruited at considerably higher frequency than all 200
 native genera considered. This invader also responded positively to
 selective logging with both odds of being in fruit and crop sizes at least
 doubling in logged plots. Prolific seed output of B. pentamera is
 especially problematic within the lottery competition of tropical
 rainforest gap tree communities, in which prominence in the seed rain is
 particularly important. Furthermore, the reproductive response of B.
 pentamera to selective logging suggests that this harvesting practice may
 have a considerable role in facilitating this invasion in Southeast Asia.

title: Data from: Persistence of a Wolbachia infection frequency cline in Drosophila melanogaster and the possible role of reproductive dormancy

description: Field populations of arthropods are often polymorphic for Wolbachia but
 the factors maintaining intermediate Wolbachia frequencies are generally
 not understood. In Drosophila melanogaster, Wolbachia frequencies are
 highly variable across the globe. We document the persistence of a
 Wolbachia infection frequency cline in D. melanogaster populations from
 eastern Australia across at least 20 years, with frequencies generally
 high in the tropics but lower in cool temperate regions. The results are
 interpreted using a model of frequency dynamics incorporating cytoplasmic
 incompatibility, imperfect maternal transmission and Wolbachia effects on
 fitness. Clinal variation is less pronounced in eastern North America
 which may reflect annual recolonization at higher latitudes. Limited
 samples from Africa from latitudes matching our tropical and subtropical
 samples from Australia and North America show comparably high infection
 frequencies, but some equatorial samples show lower frequencies. Adult
 dormancy across cold periods may contribute to the Australian Wolbachia
 cline. Infected flies exposed to cold conditions for an extended period
 had reduced fecundity and viability, an effect not evident in unexposed
 controls. These fitness costs may contribute to the relatively low
 Wolbachia frequencies in Australian temperate areas; whereas different
 processes, including cytoplasmic incompatibility induced by young males,
 may contribute to higher frequencies in tropical locations.

title: Data from: The structural and functional connectivity of the grassland plant Lychnis flos-cuculi

description: Understanding the relationship between structural and functional
 connectivity is essential for successful restoration and conservation
 management, particularly in intensely managed agricultural landscapes. We
 evaluated the relationship between structural and functional connectivity
 of the wetland plant Lychnis flos-cuculi in a fragmented agricultural
 landscape using landscape genetic and network approaches. First, we
 studied the effect of structural connectivity, such as geographic distance
 and various landscape elements (forest, agricultural land, settlements and
 ditch verges), on gene flow among populations as a measurement of
 functional connectivity. Second, we examined the effect of structural
 graph-theoretic connectivity measures on gene flow among populations and
 on genetic diversity within populations of L. flos-cuculi. Among landscape
 elements, forests hindered gene flow in L. flos-cuculi, whereas gene flow
 was independent of geographic distance. Among the structural
 graph-theoretic connectivity variables, only intrapopulation connectivity,
 which was based on population size, had a significant positive effect on
 gene flow, that is, more gene flow took place among larger populations.
 Unexpectedly, interpopulation connectivity of populations, which takes
 into account the spatial location and distance among populations, did not
 influence gene flow in L. flos-cuculi. However, higher observed
 heterozygosity and lower inbreeding was observed in populations
 characterised by higher structural interpopulation connectivity. This
 finding shows that a spatially coherent network of populations is
 significant for maintaining the genetic diversity of populations.
 Nevertheless, lack of significant relationships between gene flow and most
 of the structural connectivity measures suggests that structural
 connectivity does not necessarily correspond to functional connectivity.

title: Data from: Environmental DNA (eDNA) detects the invasive rusty crayfish (Orconectes rusticus) at low abundances

description: Early detection is invaluable for the cost-effective control and
 eradication of invasive species, yet many traditional sampling techniques
 are ineffective at the low population abundances found at the onset of the
 invasion process. Environmental DNA (eDNA) is a promising and sensitive
 tool for early detection of some invasive species, but its efficacy has
 not yet been evaluated for many taxonomic groups and habitat types. We
 evaluated the ability of eDNA to detect the invasive rusty crayfish
 Orconectes rusticus, and to reflect patterns of its relative abundance, in
 upper Midwest, USA inland lakes. We paired conventional baited trapping as
 a measure of crayfish relative abundance with water samples for eDNA,
 which were analysed in the laboratory with a qPCR assay. We modelled
 detection probability for O. rusticus eDNA using relative abundance and
 site characteristics as covariates, and also tested the relationship
 between eDNA copy number and O. rusticus relative abundance. We detected
 O. rusticus eDNA in all lakes where this species was collected by
 trapping, down to low relative abundances, as well as in two lakes where
 trap catch was zero. Detection probability of O. rusticus eDNA was
 well-predicted by relative abundance of this species and lake water
 clarity. However there was poor correspondence between eDNA copy number
 and O. rusticus relative abundance estimated by trap catches. Synthesis
 and applications. Our study demonstrates a field and laboratory protocol
 for eDNA monitoring of crayfish invasions, with results of statistical
 models that provide guidance of sampling effort and detection
 probabilities for researchers in other regions and systems. We propose
 eDNA be included as a tool in surveillance for invasive or imperilled
 crayfishes and other benthic arthropods.

title: Data from: Differential effects of maternal yolk androgens on male and female offspring: a role for sex-specific selection?

description: Maternal hormones are important mediators of prenatal maternal effects in
 animals. Although their effects on offspring phenotype are often
 sex-specific, the reason why sometimes sons are more sensitive to prenatal
 hormone exposure and sometimes daughters is not well understood. Here I
 combine an experimental manipulation of yolk testosterone concentration in
 the egg and quantification of selection acting on yolk androgen-sensitive
 traits in a natural population of great tits (Parus major) with a
 literature review to test the hypothesis that sex-specific selection on
 traits affected by yolk androgens determines which sex is more sensitive
 to prenatal hormone exposure. An experimental increase of the testosterone
 content in the egg boosted the post-hatching growth of male, but not
 female great tit nestlings. However, I found no evidence that survival
 selection on body mass or size is acting differently in the two sexes. A
 literature review revealed that yolk androgen manipulations affect the
 growth of males and females differently across species. Interestingly, in
 studies performed in the wild a significant association between the
 strength and direction of sexual size dimorphism and sex-specific
 sensitivities to yolk androgens was observed. In studies performed in
 captivity, no such relationship was found. Thus, across species there is
 some evidence that sex-specific selection on body size influences how
 strongly growth trajectories of males and females are affected by
 maternally-derived yolk androgens.

title: Data from: Females discriminate against heterospecific sperm in a natural hybrid zone

description: When hybridization is maladaptive, species-specific mate preferences are
 selectively favored, but low mate availability may constrain
 species-assortative pairing. Females paired to heterospecifics may then
 benefit by copulating with multiple males and subsequently favoring sperm
 of conspecifics. Whether such mechanisms for biasing paternity toward
 conspecifics act as important reproductive barriers in socially monogamous
 vertebrate species remains to be determined. We use a combination of
 long-term breeding records from a natural hybrid zone between collared and
 pied flycatchers (Ficedula albicollis and F. hypoleuca), and an in vitro
 experiment comparing conspecific and heterospecific sperm performance in
 female reproductive tract fluid, to evaluate the potential significance of
 female cryptic choice. We show that the females most at risk of
 hybridizing (pied flycatchers) frequently copulate with multiple males and
 are able to inhibit heterospecific sperm performance. The negative effect
 on heterospecific sperm performance was strongest in pied flycatcher
 females that were most likely to have been previously exposed to collared
 flycatcher sperm. We thus demonstrate that a reproductive barrier acts
 after copulation but before fertilization in a socially monogamous
 vertebrate. While the evolutionary history of this barrier is unknown, our
 results imply that there is opportunity for it to be accentuated via a
 reinforcement-like process.

title: Data from: Crossing phenotype heritability and candidate gene expression in grafted black-lipped pearl oyster Pinctada margaritifera, an animal chimera

description: Grafting mantle tissue of a donor pearl oyster into the gonad of a
 recipient oyster results in the formation of a chimera, the pearl sac. The
 phenotypic variations of this chimera are hypothesized to be the result of
 interactions between the donor and recipient genomes. In this study, the
 heritability of phenotypic variation and its association with gene
 expression were investigated for the first time during P. margaritifera
 pearl production. Genetic variance was evaluated at different levels, 1)
 before the graft operation (expression in graft tissue), 2) after grafting
 (pearl sac tissue expression in chimera) and 3) on the product of the
 graft (pearl phenotype traits) based on controlled bi-parental crosses and
 the F1 generation. Donor related genetic parameter estimates clearly
 demonstrate heritability for nacre weight and thickness, darkness and
 colour, surface defects and grade, which signifies a genetic basis in the
 donor oyster. In graft relative gene expression, the value of heritability
 was superior to 0.20 in for almost all genes, while in pearl sac,
 heritability estimates were low (h² &lt; 0.10) (except for CALC1 and
 Aspein). Pearl sac expression seems to be more influenced by residual
 variance than the graft, which can be explained by environmental effects
 that influence pearls sac gene expression and act as a recipient additive
 genetic component. The interactions between donor and recipient are very
 complex and further research is required to understand the role of the
 recipient oysters on pearl phenotypic and gene expression variances.

title: Data from: The evolution of sexually dimorphic tail feathers is not associated with tail skeleton dimorphism

description: Sexual selection can influence the evolution of sexually dimorphic
 exaggerated display structures. Herein, we explore whether such costly
 ornamental integumentary structures evolve independently or if they are
 correlated with phenotypic change in the associated skeletal system. In
 birds, elongate tail feathers have frequently evolved in males and are
 beneficial as intraspecific display structures but impart a
 locomotor/energetic cost. Using the sexually dimorphic tail feathers of
 several passeriform species as a model system, we test the hypothesis that
 taxa with sexually dimorphic tail feathers also exhibit sexual dimorphism
 in the caudal skeleton that supports the muscles and integument of the
 tail apparatus. Caudal skeletal morphology is quantified using both
 geometric morphometrics and linear morphometrics across four sexually
 dimorphic passeriform species and four closely related monomorphic
 species. Sexual dimorphism is assessed using permutational MANOVA. Sexual
 dimorphism in caudal skeletal morphology is found only in those taxa that
 exhibit active functional differences in tail use between males and
 females. Thus, dimorphism in tail feather length is not necessarily
 correlated with the evolution of caudal skeletal dimorphism. Sexual
 selection is sufficient to generate phenotypic divergence in integumentary
 display structures between the sexes, but these change are not reflected
 in the underlying caudal skeleton. This suggests that caudal feathers and
 bones evolve semi-independently from one another and evolve at different
 rates in response to different types of selective pressures.
