title: Data from: Enhanced male coloration after immune challenge increases reproductive potential

description: In many animal species, females select a mate on the basis of the
 expression of secondary sexual traits. A prevalent theory suggests that
 male ornaments are reliable indicators of immunocompetence, because the
 cost of immune function prevents cheating. However, sexual signalling is a
 component of males’ reproductive effort, and an immune challenge may also
 alter the organism’s perceived future prospects and hence their signalling
 effort. In this study, to investigate the consequences of mounting an
 immune response on signalling effort, blue-footed booby males (Sula
 nebouxii) during courtship were inoculated with diphtheria–tetanus
 vaccine. We found that, after this immune challenge, on average males
 increased their signalling effort but lost more body mass compared to
 control males. Importantly, vaccination affected the partner’s
 reproductive decisions: compared to control females, females paired with
 vaccinated males laid eggs earlier, and increased clutch volume in early
 pairs. Overall, our results suggest that blue-footed booby males invest
 more in sexual signals when future breeding opportunities are at risk,
 eliciting a greater reproductive investment by their partners. Increased
 signaling effort by infected individuals may contrast the idea of sexual
 ornaments as signals of infection status.

title: Data from: Rat aversion to isoflurane versus carbon dioxide

description: Some experts suggest that sedation of laboratory rodents with isoflurane
 before euthanasia with carbon dioxide (CO2) is a humane alternative to
 euthanasia with CO2 alone, but little research has compared aversion to
 these agents. Albino rats were tested in a light/dark box where they had
 the choice between remaining in a dark compartment filling with isoflurane
 or CO2, or escaping to a lit compartment. Experiment 1 validated the
 procedure by confirming that rats responded to agent and light intensity.
 In Experiment 2, 9/16 and 0/16 rats remained in the dark compartment until
 recumbent when initially exposed to isoflurane and CO2, respectively. In
 Experiment 3, more rats remained in the dark compartment until recumbent
 during initial (10/16) versus re-exposure (1/16) to isoflurane. These
 results indicate that initial exposure to CO2 is more aversive than
 isoflurane, and that re-exposure to isoflurane is more aversive than
 initial exposure. We conclude that sedation with isoflurane is a
 refinement over euthanasia with CO2 alone for rats that have not been
 previously exposed to inhalant anaesthetics.

title: Data from: Feces production as a form of social immunity in an insect with facultative maternal care

description: Background: Social animals have the unique capability of mounting social
 defenses against pathogens. Over the last decades, social immunity has
 been extensively studied in species with obligatory and permanent forms of
 social life. However, its occurrence in less derived social systems and
 thus its role in the early evolution of group-living remains unclear.
 Here, we investigated whether lining nests with feces is a form of social
 immunity against microbial growth in the European earwig Forficula
 auricularia, an insect with temporary family life and facultative maternal
 care. Results: Using a total of 415 inhibition zone assays, we showed that
 earwig feces inhibit the growth of two GRAM+ bacteria, two fungi, but not
 of a GRAM- bacteria. These inhibitions did not result from the consumed
 food or the nesting environment. We then demonstrated that the
 antimicrobial activity against fungus was higher in offspring than
 maternal feces, but that this difference was absent against bacteria.
 Finally, we showed that family interactions inhibited the antibacterial
 activity of maternal frass against one of the two GRAM+ bacteria, whereas
 they had no effect on the one of nymphal frass. By contrast, antifungal
 activities of the frass were independent of mother-offspring interactions.
 Conclusion: These results demonstrate that social immunity occurs in a
 species with simple and facultative social life, and thus shed light on
 the general importance of this process in the evolution of group-living.
 These results also emphasize that defecation can be under selection for
 other life-history traits than simple waste disposal.

title: Data from: Nectar robbing: a common phenomenon mainly determined by accessibility constraints, nectar volume and density of energy rewards

description: Nectar robbers use a hole made in the perianth to extract nectar. Since
 robbers may modify plant fitness, they play an important role by driving
 evolution on floral traits, shaping population structure and influencing
 community dynamics. Although nectar robbing is widespread in angiosperms,
 the causes and ecological implications of this behaviour on large
 ecological scales are still unexplored. Our aim is to study the frequency
 of nectar robbing in plants of temperate and tropical regions and examine
 its association with plant traits. We characterised the levels of nectar
 robbing in 88 species of Mediterranean, Alpine, Antillean and Andean plant
 communities and identified the most important nectar robbers. We analysed
 associations between the levels of robbing and floral morphology,
 production and density of energy rewards, mechanisms of protection against
 nectar robbers, plant life form and geographic origin. Nectar robbing was
 present at all sampling sites. Within communities two patterns of robbing
 levels related to the diversity and specialization of robbers were
 detected. In most communities one plant species presented very high levels
 of robbing while other species had intermediate to low robbing levels.
 There, nectar robbers are opportunists, robbing highly rewarding plants.
 In the Andean community the high specialization of several co-existing
 flowerpiercers produced an even pattern of robbing levels in the plant
 community. Plants with long flowers, abundant nectar and a high energy
 density are more likely to be robbed by both insects and birds. A high
 aggregation of the flowers within the plants and the presence of long
 calyxes and bracts are associated to low robbing rates by insects and to a
 lesser extent by birds. Besides the morphological constraints that operate
 on a single flower basis, nectar robbing is a phenomenon dependent upon
 the density of energy rewards reflecting the presence of mechanisms on
 higher ecological scales.

title: Data from: The quick are the dead: pheasants that are slow to reverse a learned association survive for longer in the wild

description: Cognitive abilities likely evolve through natural selection if they
 provide individuals with fitness benefits. A growing number of studies
 demonstrate a positive relationship between performance in psychometric
 tasks and (proxy) measures of fitness. We assayed the performance of 154
 Common Pheasant Phasianus colchicus chicks on tests of acquisition and
 reversal learning, using a different set of chicks and different set of
 cue types (spatial location and colour) in each of two years and then
 followed their fates after release into the wild. Across all birds,
 individuals that were slow to reverse previously learned associations were
 more likely to survive to four months old. For heavy birds, individuals
 that rapidly acquired an association had improved survival to four months,
 whereas for light birds, slow acquirers were more likely to be alive. Slow
 reversers also exhibited less exploratory behaviour in assays when five
 weeks old. Fast acquirers visited more artificial feeders after release.
 By contrast to most other studies, we showed that apparently ‘poor’
 cognitive performance (slow reversal speed suggesting low behavioural
 flexibility) correlates with fitness benefits in at least some
 circumstances. This correlation suggests a novel mechanism by which
 continued exaggeration of cognitive abilities may be constrained.

title: Data from: Economic thermoregulatory response explains mismatch between thermal physiology and behavior in newts

description: Temperature is an important factor determining distribution and abundance
 of organisms. Predicting the impact of warming climate on ectotherm
 populations requires information about species thermal requirements,
 so-called thermal niche. The characterization of thermal niche remains a
 complicated task. We compared the applicability of two indirect
 approaches, based on reaction norm (aerobic scope curve) and optimality
 (preferred body temperature) concepts, for indirect estimation of thermal
 niche while using newts, Ichthyosaura alpestris, as a study system. If the
 two approaches are linked, then digesting newts should keep their body
 temperatures close to values maximizing aerobic scope for digestion. After
 feeding, newts maintained their body temperatures within a narrower range
 than did hungry individuals. The range of preferred body temperatures was
 well below the temperature maximizing aerobic scope for digestion. Optimal
 temperatures for factorial aerobic scope fell within the preferred body
 temperature range of digesting individuals. We conclude that digesting
 newts prefer body temperatures which are optimal for the maximum aerobic
 performance but relative to the maintenance costs. What might be termed
 the economic thermoregulatory response explains the mismatch between
 thermal physiology and behaviour in this system.

title: Data from: Fine-scale diet of the Australian sea lion (Neophoca cinerea) using DNA-based analysis of faeces.

description: We applied DNA-based faecal analysis to determine the diet of female
 Australian sea lions (n = 12) from two breeding colonies in South
 Australia. DNA dietary components of fish and cephalopods were amplified
 using the polymerase chain reaction and mitochondrial DNA primers
 targeting the short (~100 base pair) section of the 16S gene region. Prey
 diversity was determined by sequencing ~50 amplicons generated from clone
 libraries developed for each individual. Faecal DNA was also combined and
 cloned from multiple individuals at each colony and fish diversity
 determined. Diets varied between individuals and sites. Overall, DNA
 analysis identified a broad diversity of prey comprising 23 fish and five
 cephalopod taxa, including many species not previously described as prey
 of the Australian sea lion. Labridae (wrasse), Monacanthidae
 (leatherjackets) and Mullidae (goat fish) were important fish prey taxa.
 Commonly identified cephalopods were Octopodidae (octopus), Loliginidae
 (calamary squid) and Sepiidae (cuttlefish). Comparisons of fish prey
 diversity determined by pooling faecal DNA from several samples provided a
 reasonable but incomplete resemblance (55–71%) to the total fish diversity
 identified across individual diets at each site. Interpretation of diet
 based on the recovery of prey hard-parts identified one cephalopod beak
 (Octopus sp.) and one fish otolith (Parapriacanthus elongatus). The
 present study highlights the value of DNA-based analyses and their
 capabilities to enhance information of trophic interactions.

title: Data from: Intermediate kinematics produce inferior feeding performance in a classic case of natural hybridization

description: Selection on naturally-occurring hybrid individuals is a key component of
 speciation theory, but few studies examine the functional basis of hybrid
 performance. We examine the functional consequences of hybridization in
 nature using the freshwater sunfishes (Centrarchidae), where natural
 hybrids have been studied for over a century and a half. We examined
 bluegill (Lepomis macrochirus), green sunfish (Lepomis cyanellus), and
 their naturally-occurring hybrid using prey capture kinematics and
 morphology to parameterize suction feeding simulations on divergent
 parental resources. Hybrid individuals exhibited intermediate kinematics
 between the two parental species. However, performance assays indicated
 that hybrids display performance most similar to the worse-performing
 species for a given parental resource. Our results show that intermediate
 hybrid phenotypes can be impaired by a less than intermediate performance
 and hence suffer a larger loss in fitness than could be inferred from
 morphology alone.

title: Data from: Do baseline glucocorticoids simultaneously represent fitness and environmental quality in a declining aerial insectivore?

description: Glucocorticoids (GCs) are often interpreted as indicators of disturbance,
 habitat quality, and fitness in wild populations. However, since most
 investigations have been unable to examine habitat variability, GC levels,
 and fitness simultaneously, such interpretations remain largely
 unvalidated. We combined a quantification of two habitat types, a
 manipulation of foraging ability (feather-clipping just prior to nestling
 rearing), multiple baseline plasma GC measures, and multi-year
 reproductive monitoring to experimentally examine the linkages between
 habitat quality, GCs, and fitness in female tree swallows Tachycineta
 bicolor. Control females experiencing the higher early-season food
 resources of inland–pasture habitat laid larger clutches, but fledged an
 equal number but lower mass offspring compared to those in
 riparian–cropland habitat. Despite these differences in reproductive
 success, females nesting in the two habitat types did not differ in
 baseline GC levels at the early- or late-breeding stage. Feather-clipping
 reduced provisioning rate in both habitat types. However, baseline GC
 levels were affected in a habitat-specific way; only individuals in
 inland–pasture habitats showed an increase in GCs. Despite this difference
 in GC levels, the manipulation did not influence offspring mass,
 reproductive output, adult return rate (a proxy for survival) to the
 following year, or reproductive success in the subsequent year.
 Nonetheless, regardless of treatment, individuals with higher GC levels
 during the late breeding stage returned in the following year with higher
 GC levels at incubation, indicating a long-term effect on future GC
 levels. Our results indicate that environmental changes (e.g. foraging
 conditions) can have consequences for body condition, behaviour, and
 current and future baseline GC levels without concomitant influences on
 fitness, and that differences in fitness components between habitats may
 not be reflected in baseline GC levels. These results illustrate that
 baseline GCs may not simultaneously reflect environmental quality and
 fitness, potentially limiting their application in ecological and
 conservation settings.

title: Data from: Selfish mothers indeed! Resource-dependent conflict over extended parental care in free-ranging dogs

description: Parent–offspring conflict (POC) theory provides an interesting premise for
 understanding social dynamics in facultatively social species. In
 free-ranging dogs, mothers increase conflict over extended parental care
 with their pups beyond the weaning stage. In this study, we investigated
 whether resource quality affects POC in the dogs that typically live in a
 highly competitive environment as scavengers. We built a theoretical model
 to predict the alternative options available to the mother in the context
 of food sharing with her pups when protein-rich food (meat) is provided,
 as compared to carbohydrate-rich food (biscuits). We fit the mothers’
 response from experimental data to the model and show that the mothers
 choose a selfish strategy, which can in turn ensure higher lifetime
 reproductive success, while depriving the current litter access to better
 resources. These results have interesting implications for understanding
 the social dynamics of the dogs, and the emergence of facultative
 sociality in a species that evolved from strongly social ancestors. We
 speculate that the tendency of increased conflict in resource-rich
 conditions might have driven the process of domestication in the ancestors
 of dogs which defected from their groups in favour of richer resources
 around human settlements.

title: Data from: Corrosion resistant systems of formate packer fluid for G3/N80/TP110SS pipes at high temperature, high pressure and high H2S/CO2 ratios

description: A series of corrosion problems caused by high-temperature, high-pressure
 and high-acid gas environments has been an issue in oil and gas production
 for a long time. During the development of a high-acid gas field, the
 petroleum pipe is subjected to many aspects of corrosion, and the
 corrosion mechanism is complicated by the condition of the coexistence of
 H2S/CO2/O2. Based on the study of the corrosion problem associated with
 the formate packer fluid in Southwest China, three kinds of steels were
 studied for corrosion prevention in the Alloy G3/N80 Steel/TP110SS Steel.
 The study shows that the corrosion rate of the formate packer fluid is
 low, but corrosion is severe in environments characterised by high
 temperatures, high pressures and high acid gas contents. Based on the
 consideration of cost and the difficulty of realization, an anti-corrosion
 system was constructed based on the existing packer fluid, mainly through
 the introduction of a variety of anti-corrosion additives. Through the
 selection of various additives and corrosion experiments, a corrosion
 protection system of formate packer fluid was developed. Corrosion tests
 show that the corrosion rate of the system must be less than 0.076 mm/a to
 achieve the purpose of corrosion protection. The formate packer fluid with
 corrosion protection can meet the needs of the current application.

title: Data from: Expression of parasite genetic variation changes over the course of infection: implications of within-host dynamics for the evolution of virulence

description: How infectious disease agents interact with their host changes during the
 course of infection and can alter the expression of disease-related
 traits. Yet by measuring parasite life-history traits at one or few
 moments during infection, studies have overlooked the impact of variable
 parasite growth trajectories on disease evolution. Here we show that
 infection-age-specific estimates of host and parasite fitness components
 can reveal new insight into the evolution of parasites. We do so by
 characterizing the within-host dynamics over an entire infection period
 for five genotypes of the castrating bacterial parasite Pasteuria ramosa
 infecting the crustacean Daphnia magna. Our results reveal that genetic
 variation for parasite-induced gigantism, host castration and parasite
 spore loads increases with the age of infection. Driving these patterns
 appears to be variation in how well the parasite maintains control of host
 reproduction late in the infection process. We discuss the evolutionary
 consequences of this finding with regard to natural selection acting on
 different ages of infection and the mechanism underlying the maintenance
 of castration efficiency. Our results highlight how elucidating
 within-host dynamics can shed light on the selective forces that shape
 infection strategies and the evolution of virulence.
