title: Data from: Evaluating female remating rates in light of spermatophore degradation in Heliconius butterflies: pupal-mating monandry versus adult-mating polyandry

description: 1) Butterflies are frequently used in comparative studies of sexual
 selection because of their diverse mating systems. In Heliconius, the two
 major clades in the genus are characterized by contrasting pupal-mating
 and adult-mating strategies. Adult-mating females are considered to be
 promiscuous while pupal-mating females are thought to be monandrous. 2)
 Counting spermatophores in female Lepidoptera is a common method for
 assessing patterns of female remating. However, in pupal-mating Heliconius
 butterflies spermatophores can become completely degraded leading to a
 potential underestimation of female remating rates. 3) We qualitatively
 characterized the different states of spermatophore degradation, and
 showed that complete degradation takes approximately three weeks in
 captive-bred H. erato females. 4) We counted spermatophores and/or assayed
 spermatophore degradation in &gt;500 Heliconius females across 28
 species sampled from natural populations. Among pupal-maters these
 observations yielded a few rare observations of double mating by recently
 eclosed females, but generally indicated a lack of rematings. In contrast,
 approximately 25% of sampled adult-mating females remated at least once.
 5) Using a novel statistical analysis we estimated remating rates from
 patterns of spermatophore degradation or counts stratified by age, as
 indicated by wing-wear. This analysis showed no statistically significant
 evidence for remating for the pupal-mating H. erato while significant
 remating rates were detected for adult-mating species. 6) Our results
 support the established view of Heliconius mating systems in which
 pupal-maters are largely monandrous, while adult-maters are polyandrous.

title: Data from: Biotic interactions and seed deposition rather than abiotic factors determine recruitment at elevational range limits of an alpine tree

description: 1. Abiotic factors, biotic interactions and dispersal ability determine
 the spatial distribution of species. Theory predicts that abiotic
 constraints set range limits under harsh climatic conditions and biotic
 interactions set range limits under benign climatic conditions, whereas
 dispersal ability should limit both ends of the distribution. However,
 empirical studies exploring how these three components jointly affect
 species across environmental gradients are scarce. 2. Here we present a
 study that jointly examines these factors to investigate the constraints
 of the recruitment of Swiss stone pine (Pinus cembra) across and beyond
 its elevational range in the Swiss Alps. We investigated the natural
 recruitment of pines and additionally conducted seed transplant
 experiments to test how much abiotic factors (mean summer and winter
 temperatures, soil moisture), biotic interactions (understorey vegetation
 cover, canopy cover, seed predation) and / or seed deposition by the
 Spotted nutcracker (Nucifraga caryocatactes) affect pine establishment. 3.
 We found significant effects of biotic interactions and seed deposition by
 Spotted nutcrackers on the recruitment of Swiss stone pine at both the
 upper and lower elevational range, but could not detect significant
 effects of abiotic factors. Importantly, dispersal limitation rather than
 temperature and soil moisture restricted the recruitment of pines at the
 upper elevational range. 4. Synthesis. Our study highlights the importance
 of biotic interactions and dispersal ability in setting the upper range
 limits of species that have been regarded as mainly controlled by climate.
 This suggests that potential range shifts of plants in response to climate
 warming may strongly depend on seed dispersal and biotic interactions and
 not only on climatic factors.

title: Data from: Isospectrals of non-uniform Rayleigh beams with respect to their uniform counterparts

description: In this paper, we look for non-uniform Rayleigh beams isospectral to a
 given uniform Rayleigh beam. Isospectral systems are those that have the
 same spectral properties, i.e. the same free vibration natural frequencies
 for a given boundary condition. A transformation is proposed that converts
 the fourth-order governing differential equation of non-uniform Rayleigh
 beam into a uniform Rayleigh beam. If the coefficients of the transformed
 equation match with those of the uniform beam equation, then the
 non-uniform beam is isospectral to the given uniform beam. The
 boundary-condition configuration should be preserved under this
 transformation. We present the constraints under which the boundary
 configurations will remain unchanged. Frequency equivalence of the
 non-uniform beams and the uniform beam is confirmed by the finite-element
 method. For the considered cases, examples of beams having a rectangular
 cross section are presented to show the application of our analysis.

title: Data from: Effects of litter size and quality on processing by decomposers in a savannah aquatic system

description: Plants can have decreased litter leaf size and quality by fragmentation or
 when exposed to drought, which can affect ecosystem functioning. We
 evaluated the organic matter fragment size and quality on feeding
 preference and case construction by Phylloicus larvae, and leaf processing
 by microorganisms from savannah headwater streams. Containers (16 cm x
 16cm x 12 cm, ~ 3L) with either Phylloicus (cases removed; n = 16) or
 microorganisms (n = 16) were supplied with litter from the species Inga
 laurina, Maprounea guianensis and Richeria grandis, cut into discs of
 18.7, 13.2 and 8.1 mm size (3 sizes × 3 species = 9 discs per container).
 Smaller leaf discs of higher litter quality increased leaf mass loss,
 mainly by higher microbial activity. This likely occurs due to increased
 surface area to volume ratio in smaller, higher quality litter. Phylloicus
 exhibited preferences for fragment size only for case building, using
 mostly larger leaves of M. guianensis and R. grandis, likely due increased
 robustness for case formation. Microorganisms presented similar potential
 to Phylloicus for decomposing organic matter. Microbial decomposition
 resulted in ~20% mass loss compared to 30% in Phylloicus despite the
 higher invertebrate individual biomass (8% for case-building and 24% for
 food resource). This suggests that a decrease in leaf size after exposure
 to drought may lead to increased microbial decomposition. However, our
 results suggest that although shredders typically have low densities in
 savannah streams, they nonetheless play key roles in energy flow by leaf
 litter processing due to higher biomass.

title: Data from: Male-mediated species recognition among African weakly electric fishes

description: Effective communication among sympatric species is often instrumental for
 behavioural isolation, where the failure to successfully discriminate
 between potential mates could lead to less fit hybrid offspring.
 Discrimination between con- and heterospecifics tends to occur more often
 in the sex that invests more in offspring production, i.e. females, but
 males may also mediate reproductive isolation. In this study, we show that
 among two Campylomormyrus African weakly electric fish species, males
 preferentially associate with conspecific females during choice tests
 using live fish as stimuli, i.e. when all sensory modalities potentially
 used for communication were present. We then conducted playback
 experiments to determine whether the species-specific electric organ
 discharge (EOD) used for electrocommunication serves as the cue for this
 conspecific association preference. Interestingly, only C.
 compressirostris males associated significantly more with the conspecific
 EOD waveform when playback stimuli were provided, while no such
 association preference was observed in C. tamandua males. Given our
 results, the EOD appears to serve, in part, as a male-mediated pre-zygotic
 isolation mechanism among sympatric species. However, the failure of C.
 tamandua males to discriminate between con- and heterospecific playback
 discharges suggests that multiple modalities may be necessary for species
 recognition in some African weakly electric fish species.

title: Data from: When condition trumps location: seed consumption by fruit-eating birds removes pathogens and predator attractants

description: Seed ingestion by frugivorous vertebrates commonly benefits plants by
 moving seeds to locations with fewer predators and pathogens than under
 the parent. For plants with high local population densities, however,
 movement from the parent plant is unlikely to result in ‘escape’ from
 predators and pathogens. Changes to seed condition caused by gut passage
 may also provide benefits, yet are rarely evaluated as an alternative.
 Here, we use a common bird-dispersed chilli pepper (Capsicum chacoense) to
 conduct the first experimental comparison of escape-related benefits to
 condition-related benefits of animal-mediated seed dispersal. Within
 chilli populations, seeds dispersed far from parent plants gained no
 advantage from escape alone, but seed consumption by birds increased seed
 survival by 370% – regardless of dispersal distance – due to removal
 during gut passage of fungal pathogens and chemical attractants to
 granivores. These results call into question the pre-eminence of escape as
 the primary advantage of dispersal within populations and document two
 overlooked mechanisms by which frugivores can benefit fruiting plants.

title: Data from: Seasonal variation in foraging group size of crab-eating foxes and hoary foxes in the Cerrado biome, Central Brazil

description: In regions with a pronounced dry season, such as the Cerrado Biome
 (Brazilian savannah), climate seasonality may affect food availability for
 canid species and, consequently, their foraging behavior. We investigated
 seasonal variation in foraging group size of crab-eating foxes (Cerdocyon
 thous) and hoary foxes (Pseudalopex vetulus) in the Cerrado region for
 three consecutive years. Data were obtained by direct observations of
 foraging foxes during spotlight surveys. Both species were sighted
 foraging individually or in pairs with or without their juvenile
 offspring. However, crab-eating foxes foraged in pairs more frequently in
 the wet season and individually more frequently in the dry season whereas
 hoary foxes foraged mostly individually throughout the year. The higher
 frequency of solitary foragers in the dry season is possibly a response to
 the seasonal shortages in the availability of clumped and locally abundant
 food resources such as fruit and insects, important items in the diet of
 the crab-eating fox during the wet season. The absence of seasonal
 variation in foraging group size of the hoary fox may be related to its
 specialized food habits, since termites predominate in the diet of this
 species in both seasons.

title: Data from: The role of abiotic and biotic factors in determining coexistence of multiple pollinators in the yucca-yucca moth mutualism

description: The determinants of a species' geographic distribution are a
 combination of both abiotic and biotic factors. Environmental niche
 modeling of climatic factors has been instrumental in documenting the role
 of abiotic factors in a species' niche. Integrating this approach
 with data from species interactions provides a means to assess the
 relative roles of abiotic and biotic components. Here, we examine whether
 the high host specificity typically exhibited in the active pollination
 mutualism between yuccas and yucca moths is the result of differences in
 climatic niche requirements that limit yucca moth distributions or the
 result of competition among mutualistic moths that would co-occur on the
 same yucca species. We compared the species distribution models of two
 Tegeticula pollinator moths that use the geographically widespread plant
 Yucca filamentosa. Tegeticula yuccasella occurs throughout eastern North
 America whereas T. cassandra is restricted to the southeastern portion of
 the range, primarily occurring in Florida. Species distribution models
 demonstrate that T. cassandra is restricted climatically to the
 southeastern United States and T. yuccasella is predicted to be able to
 live across all of eastern North America. Data on moth abundances in
 Florida demonstrate that both moth species are present on Y. filamentosa;
 however, T. cassandra is numerically dominant. Taken together, the results
 suggest that moth geographic distributions are heavily influenced by
 climate, but competition among pollinating congeners will act to restrict
 populations of moth species that co-occur.

title: Data from: Bottlenecks and inbreeding depression in autotetraploids

description: Inbreeding depression is dependent on the ploidy of populations and can
 inhibit the evolution of selfing. While polyploids should generally harbor
 less inbreeding depression than diploids at equilibrium, it has been
 unclear whether this pattern holds in non-equilibrium conditions following
 bottlenecks. We use stochastic individual based simulations to determine
 the effects of population bottlenecks on inbreeding depression in diploids
 and autotetraploids, in addition to cases where neo-autotetraploids form
 from the union of unreduced gametes. With a ploidy-independent dominance
 function based on enzyme kinetics, inbreeding depression is generally
 lower in autotetraploids for fully and partially recessive mutations. Due
 to the sampling of more chromosomes during reproduction, bottlenecks
 generally reduce inbreeding depression to a lesser extent in
 autotetraploids. All else being equal, population bottlenecks may have
 ploidy dependent effects for another reason – in some cases mating between
 close relatives temporarily increases inbreeding depression in
 autotetraploids by increasing the frequency of the heterozygous genotype
 harboring the most harmful mutations. When neo-autotetraploids are formed
 by few individuals, inbreeding depression is dramatically reduced, given
 extensive masking of harmful mutations following whole genome duplication.
 This effect persists as nascent tetraploids reach mutation-selection-drift
 balance, providing a transient period of permissive conditions favoring
 the evolution of selfing.

title: Data from: Serotonin depletion-induced maladaptive aggression requires the presence of androgens

description: The sex hormone testosterone and the neurotransmitter serotonin exert
 opposite effects on several aspects of behavior including territorial
 aggression. It is however not settled if testosterone exerts its
 pro-aggressive effects by reducing serotonin transmission and/or if the
 anti-aggressive effect of serotonin requires the presence of the androgen.
 Using the resident intruder test, we now show that administration of the
 serotonin synthesis inhibitor para-chlorophenylalanine (300 mg/kg x 3
 days) increases the total time of attack as well as the percentage amount
 of social behavior spent on attack but not that spent on threat – i.e.
 that it induces a pattern of unrestricted, maladaptive aggression – in
 gonadectomized C57Bl/6 male mice receiving testosterone replacement; in
 contrast, it failed to reinstate aggression in those not given
 testosterone. Whereas these results suggest the pro-aggressive effect of
 testosterone to be independent of serotonin, and not caused by an
 inhibition of serotonergic activity, the pCPA-induced induction of
 maladaptive aggression appears to require the presence of the hormone. In
 line with these findings, pCPA enhanced the total time of attack as well
 the relative time spent on attacks but not threats also in wild-type
 gonadally intact male C57Bl/6 mice, but failed to reinstate aggression in
 mice rendered hypo-aggressive by early knock-out of androgen receptors in
 the brain (ARNesDel mice). We conclude that androgenic deficiency does not
 dampen aggression by unleashing an anti-aggressive serotonergic influence;
 instead serotonin seems to modulate aggressive behavior by exerting a
 parallel-coupled inhibitory role on androgen-driven aggression, which is
 irrelevant in the absence of the hormone, and the arresting of which leads
 to enhanced maladaptive aggression.

title: Data from: Individual differences in boldness influence patterns of social interactions and the transmission of cuticular bacteria among group-mates

description: Despite the importance of host attributes for the likelihood of associated
 microbial transmission, individual variation is seldom considered in
 studies of wildlife disease. Here, we test the influence of host
 phenotypes on social network structure and the likelihood of cuticular
 bacterial transmission from exposed individuals to susceptible group-mates
 using female social spiders (Stegodyphus dumicola). Based on the
 interactions of resting individuals of known behavioural types, we
 assessed whether individuals assorted according to their behavioural
 traits. We found that individuals preferentially interacted with
 individuals of unlike behavioural phenotypes. We next applied a
 GFP-transformed cuticular bacterium, Pantoea sp., to individuals and
 allowed them to interact with an unexposed colony-mate for 24h. We found
 evidence for transmission of bacteria in 55% of cases. The likelihood of
 transmission was influenced jointly by the behavioural phenotypes of both
 the exposed and susceptible individuals: transmission was more likely when
 exposed spiders exhibited higher “boldness” relative to their colony-mate,
 and when unexposed individuals were in better body condition. Indirect
 transmission via contaminated silk took place in only 15% of cases. Thus,
 bodily contact appears key to transmission in this system. These data
 represent a fundamental step towards understanding how individual traits
 influence larger-scale social and epidemiological dynamics.

title: Data from: Rapid animal welfare assessment: an archaeological approach

description: The welfare of an individual depends on its capacity to overcome
 suboptimal conditions in its environment; otherwise, its physical and
 psychological health becomes compromised. A situation that clearly
 indicates lack of control of the environment is the expression of abnormal
 behaviours, such as stereotypies. This study aimed to verify the
 well-being of police horses using a new rapid form of welfare assessment:
 an archaeological approach. To this end, we sampled and quantified marks
 found on the stables, deposited as a result of abnormal behaviour. We
 cross-referenced these physical marks with veterinary records of diseases,
 such as colic, known to be associated with stress. A total of 46 horses
 were sampled and the results showed a significant medium-strength,
 positive correlation between bite mark frequency on stable doors and the
 incidence of colic. A weak significant positive correlation was found
 between length of scratch marks (from pawing) and the incidence of
 lameness. We conclude that these marks reflect the accumulated expression
 of abnormal behaviour and can provide rapid insight into the welfare of
 individual animals.
