title: Data from: Neutral fitness outcomes contradict inferences of sexual ‘coercion’ derived from male’s damaging mating tactic in a widow spider

description: Sexual conflict over mating frequency has driven the evolution of
 morphological and behavioural traits across taxa. Interactions may be
 termed ‘coercive’ and assumed to arise from conflict when male mating
 behaviours cause physical injury to females and females appear to resist
 injurious matings.However, coercion per se occurs only if the behaviour
 reduces female fitness; and such outcomes are rarely measured. Here we
 show that a damaging mating tactic, apparently adaptive for males, is not
 coercive for females. Adult male Latrodectus spiders mate with immature
 females after tearing the exoskeleton covering the female’s
 recently-developed reproductive tract, which can cause haemolymph
 bleeding. We show that, relative to pairings with adult females, males use
 reduced courtship displays when approaching immature females, which in
 some cases respond with elevated deterrent behavioural responses.
 Nevertheless, we found no reproductive cost for immature-mated females in
 terms of longevity, fertility or fecundity. Moreover, most immature-mated
 females did not produce sex pheromones as adults, so did not seek
 additional matings. Thus, despite the appearance of conflict there is no
 evidence that immature-mating is coercive. These results show it is
 critical to measure fitness outcomes, in addition to behavioural
 responses, to test for coercion.

title: Data from: Dissolved organic carbon and unimodal variation in sexual signal coloration in mosquitofish: a role for light limitation?

description: Natural selection plays an important role in the evolution of sexual
 communication systems. Here, we assess the effect of two well-known
 selection agents, transmission environment and predation, on
 interpopulation variation in sexual signals. Our model system is a series
 of 21 populations of Bahamian mosquitofish subjected to independent
 variation in optical conditions and predation risk. We show that optically
 diverse environments, caused by locally variable dissolved organic carbon
 concentrations, rather than spatial variation in predation, drove
 divergence in fin coloration (fin redness). We found a unimodal pattern of
 phenotypic variation along the optical gradient indicating a
 threshold-type response of visual signals to broad variation in optical
 conditions. We discuss evolutionary and ecological mechanisms that may
 drive such a pattern as well as the implications of non-monotonic clines
 for evolutionary differentiation.

title: Data from: Genetic variation in host plants influences the mate preferences of a plant-feeding insect

description: Many species spend their lives in close association with other organisms,
 and the environments provided by those organisms can play an important
 role as causes of variation in phenotypes. When this is the case, the
 genotypes of the individuals constituting the environment may influence
 the phenotypes of individuals living in that environment. When these
 effects are between heterospecifics, interspecific indirect genetic
 effects (IIGEs) occur. Several studies have detected IIGEs, but whether
 IIGEs contribute to variation in sexually selected traits remains
 virtually unexplored. We assessed how mate preferences in a plant-feeding
 insect are influenced by the genotype of their host plant. We established
 clone lines of a sample of host plant genotypes constituting the
 background biotic environment for a random sample of insects that we
 reared on them. We found that the insects’ mate preferences varied
 according to the clone line on which they developed. These results
 demonstrate that genetic variation in host plants has cross-trophic
 consequences on a trait that has strong effects on fitness and
 interpopulation dynamics such as diversification in communication systems.
 We discuss how IIGEs on mate preferences may influence the way in which
 selection acts, including the maintenance of variation and the promotion
 of evolutionary divergence.

title: Data from: The ontogeny of visual motor memory and its importance in handwriting and reading: a developing construct

description: Humans have evolved a remarkable ability to remember visual shapes and use
 these representations to generate motor activity (from Palaeolithic cave
 drawings through Jiahu symbols to cursive handwriting). The term
 visual–motor memory (VMM) describes this psychological ability, which must
 have conveyed an evolutionary advantage and remains critically important
 to humans (e.g. when learning to write). Surprisingly, little empirical
 investigation of this unique human ability exists—almost certainly because
 of the technological difficulties involved in measuring VMM. We deployed a
 novel technique for measuring this construct in 87 children (6–11 years
 old, 44 females). Children drew novel shapes presented briefly on a tablet
 laptop screen, drawing their responses from memory on the screen using a
 digitizer stylus. Sophisticated algorithms (using point-registration
 techniques) objectively quantified the accuracy of the children's
 reproductions. VMM improved with age and performance decreased with shape
 complexity, indicating that the measure captured meaningful developmental
 changes. The relationship between VMM and scores on nationally
 standardized writing assessments were explored with the results showing a
 clear relationship between these measures, even after controlling for age.
 Moreover, a relationship between VMM and the nationally standardized
 reading test was mediated via writing ability, suggesting VMM's wider
 importance within language development.

title: Data from: Moderate genetic drift is driven by extreme recruitment events in the invasive mollusk Crepidula fornicata

description: Effective population size (Ne) is a measure of genetic drift and is thus a
 central parameter in evolution, conservation genetics and invasion
 biology. Interestingly, in native marine species, Ne is typically several
 orders of magnitude lower than the census size. This pattern has often
 been explained by high fecundity, variation in reproductive success and
 pronounced early mortality, resulting in genetic drift across generations.
 Data documenting genetic drift and/or Ne in marine invasive species are,
 however, still scarce. We examined the importance of genetic drift in the
 invasive species Crepidula fornicata by genotyping 681 juveniles sampled
 during each annual recruitment peak over nine consecutive years in the Bay
 of Morlaix (Brittany, France). Observed variations in genetic diversity
 were partially explained by variation in recruitment intensity. In
 addition, substantial temporal genetic differentiation was documented
 (that is, genetic drift), and was attributed to nonrandom variance in the
 reproductive success of different breeding groups across years in the
 study species. Using a set of single-sample and temporal estimators for
 Ne, we estimated Ne to be three or four orders of magnitude smaller than
 the census size (Nc). On one hand, this reduction in Ne relative to Nc
 appeared congruent with, although slight higher than, values commonly
 observed in native marine species. Particular life-history traits of this
 invasive species may play an important role in buffering genetic drift. On
 the other hand, Ne still remained far below Nc, hence, possibly reducing
 the efficiency of selection effects.

title: Data from: Experimental test of phytoplankton competition for nutrients and light in poorly mixed water columns

description: A recent theory of the vertical distribution of phytoplankton considers
 how interacting niche construction processes such as resource depletion,
 behavior, and population dynamics contribute to spatial heterogeneity in
 the aquatic environment. In poorly mixed water columns with opposing
 resource gradients of nutrients and light, theory predicts that a species
 should aggregate at a single depth. This depth of aggregation, or biomass
 maximum, should change through time due to depletion of available
 resources. In addition, the depth of the aggregation should be deeper
 under low amounts of nutrient loading and shallower under higher amounts
 of nutrient loading. Theory predicts total biomass to exhibit a saturating
 relationship with nutrient supply. A surface biomass maximum limited by
 light and a deep biomass maximum limited by nutrients or co-limited by
 nutrients and light is also predicted by theory. To test this theory, we
 used a motile phytoplankton species (Chlamydomonas reinhardtii) growing in
 cylindrical plankton towers. In our experiment, the resource environment
 was strongly modified by the movement, self-shading, nutrient uptake, and
 growth of the phytoplankton. Supporting predictions, we routinely observed
 a single biomass maximum at the surface throughout the course of the
 experiment and at equilibrium under higher nutrient loading. However, at
 equilibrium, low nutrient loading led to a non-distinct biomass maximum
 with the population distributed over most of the water column instead of
 the distinct subsurface peak predicted by theory. Also supporting
 predictions, total biomass across water columns was positively related to
 nutrient supply but saturating at high nutrient supply conditions. Further
 supporting predictions, we also found evidence of light limitation for a
 surface biomass maximum and nutrient limitation for the deep biomass when
 no surface maximum was present. In addition, the light level leaving the
 bottom of the water column declined through time as the phytoplankton grew
 and was negatively related to nutrient loading. Nutrients were strongly
 depleted where biomass was present by the end of the experiment. This
 experimental study shows that the vertical distribution of phytoplankton
 may be driven by intraspecific resource competition in space.

title: Data from: No evidence of quantitative signal honesty across species of aposematic burnet moths (Lepidoptera: Zygaenidae)

description: Many defended species use conspicuous visual warning signals to deter
 potential predators from attacking. Traditional theory holds that these
 signals should converge on similar forms, yet variation in visual traits
 and the levels of defensive chemicals is common, both within and between
 species. It is currently unclear how the strength of signals and potency
 of defences might be related: conflicting theories suggest that aposematic
 signals should be quantitatively honest, or, in contrast, that investment
 in one component should be prioritised over the other, while empirical
 tests have yielded contrasting results. Here, we advance this debate by
 examining the relationship between defensive chemicals and signal
 properties in a family of aposematic Lepidoptera, accounting for
 phylogenetic relationships and quantifying coloration from the perspective
 of relevant predators. We test for correlations between toxin levels and
 measures of wing colour across 14 species of day-flying burnet and
 forester moths (Lepidoptera: Zygaenidae), protected by highly aversive
 cyanogenic glucosides, and find no clear evidence of quantitative signal
 honesty. Significant relationships between toxin levels and coloration
 vary between sexes and sampling years, and several trends run contrary to
 expectations for signal honesty. Although toxin concentration is
 positively correlated with increasing luminance contrast in forewing
 pattern in one year, higher toxin levels are also associated with paler
 and less chromatically salient markings, at least in females, in another
 year. Our study also serves to highlight important factors, including
 sex-specific trends and seasonal variation, that should be accounted for
 in future work on signal honesty in aposematic species.

title: Data from: Genetic mapping identifies a major locus spanning P450 clusters associated with pyrethroid resistance in kdr-free Anopheles arabiensis from Chad

description: Prevention of malaria transmission throughout much of Africa is dependent
 on bednets that are impregnated with pyrethroid insecticides. Anopheles
 arabiensis is the major malaria vector in Chad and efforts to control this
 vector are threatened by the emergence of pyrethroid resistance. WHO
 bioassays revealed that An. arabiensis from Ndjamena is resistant to
 pyrethroids and dichlorodiphenyltrichloroethane (DDT) but fully
 susceptible to carbamates and organophosphates. No 1014F or 1014S kdr
 alleles were detected in this population. To determine the mechanisms that
 are responsible for resistance, genetic crosses were established between
 the Ndja strain and an insecticide susceptible population from Mozambique.
 Resistance was inherited as an autosomal trait and quantitative trait
 locus (QTL) mapping identified a single major locus on chromosome 2R,
 which explained 24.4% of the variance in resistance. This QTL is enriched
 in P450 genes including 25 cytochrome P450s in total. One of these, Cyp6p4
 is 22-fold upregulated in the Ndja strain compared with the susceptible.
 Piperonyl butoxide (PBO) synergist and biochemical assays further support
 a role for P450s in conferring pyrethroid resistance in this population.

title: Data from: Mating system and genetic composition of the macaw palm (Acrocomia aculeata): implications for breeding and genetic conservation programs

description: Acrocomia aculeata (Arecaceae), a palm endemic to South and Central
 America, is a potential oil crop. Knowledge of the mating system of this
 species is limited to its reproductive biology and to studies using
 molecular markers. The present study analyzed genetic diversity between
 its developmental stages and determined its prevailing mating system in
 order to support genetic conservation and breeding programs. We tested
 nine microsatellite markers in 27 mother trees (adult plants) and 157
 offspring (juvenile plants) from the southeastern region of Brazil.
 Heterozygosity levels differed between the two studied life stages, as
 indicated by the fixation index of adult and juvenile trees, suggesting
 that selection against homozygotes occurs during the plant life cycle. The
 mating system parameters analyzed indicate that A. aculeata is
 predominantly outcrossing (allogamous). However, its low levels of selfing
 suggest that there is individual variation with regard to
 self-incompatibility, which can be a survival strategy in isolated or
 fragmented habitats. Deviations in variance effective size were detected
 because of high mating rates among relatives and correlated matings. These
 findings indicate that the main source of inbreeding results from
 biparental inbreeding in the population and that the progenies are
 predominantly composed of full-sibs. The information provided by this
 study on the ecology and reproduction dynamics of A. aculeata should be
 useful to both breeding and genetic conservation programs, allowing the
 development of more precise mathematical models and the estimation of the
 appropriate number of mother trees for seed collection.

title: Data from: Lysozyme-associated bactericidal activity in the ejaculate of a wild passerine

description: Numerous antibacterial substances have been identified in the ejaculates
 of animals and are suggested to protect sperm from bacterial-induced
 damage in both the male and female reproductive tracts. Lysozymes, enzymes
 that exhibit bactericidal activity through their ability to break down
 bacterial cell walls, are likely to be particularly important for sperm
 defence as they are part of the constitutive innate immune system and are
 thus immediately available to protect sperm from bacterial attack. Birds
 are an ideal model for studies of ejaculate antimicrobial defences because
 of the dual function of the avian cloaca (i.e. waste excretion and sperm
 transfer), yet the antibacterial activity of avian ejaculates remains
 largely unexplored and data on ejaculate lysozyme levels are only
 available for the domestic turkey (Meleagris gallopavo). Moreover,
 ejaculate lysozyme levels have not been reported for any species in the
 wild; which many argue is necessary to gain a comprehensive understanding
 of the function and dynamics of immune responses. Here, we show that
 lysozyme is present in the ejaculate of a wild passerine, the superb
 fairy-wren (Malurus cyaneus), and that the concentration of lysozyme in
 ejaculates varies substantially among males. This variation, however, is
 not associated with male condition, sperm quality or plumage colouration.
 Nevertheless, we suggest that lysozyme-associated antibacterial activity
 in ejaculates may be the target of natural and sexual selection and that
 these enzymes likely function to defend avian sperm from bacterial-induced
 damage.
