title: Data from: Stabilising survival selection on pre-senescent expression of a sexual ornament followed by a terminal decline

description: Senescence is a decrease in functional capacity, increasing mortality rate
 with age. Sexual signals indicate functional capacity, because costs of
 ornamentation ensure signal honesty, and are therefore expected to
 senesce, tracking physiological deterioration and mortality. For sexual
 traits, mixed associations with age and positive associations with life
 expectancy have been reported. However, whether these associations are
 caused by selective disappearance and/or within-individual senescence of
 sexual signals, respectively, is not known. We previously reported that
 zebra finches with redder bills had greater life expectancy, based on a
 single bill colour measurement per individual. We here extend this
 analysis using longitudinal data, and show that this finding is
 attributable to terminal declines in bill redness in the year before
 death, with no detectable change in pre-senescent redness. Additionally,
 there was a quadratic relationship between pre-senescent bill coloration
 and survival: individuals with intermediate bill redness have maximum
 survival prospects. This may reflect that redder individuals overinvest in
 coloration and/or associated physiological changes, while below average
 bill redness probably reflects poorer phenotypic quality. Together this
 pattern suggests that bill coloration is defended against physiological
 deterioration, because of mate attraction benefits, or that physiological
 deterioration is not a gradual process, but accelerates sharply prior to
 death. We discuss these possibilities in the context of the reliability
 theory of ageing and sexual selection.

title: Data from: Beyond thermal limits: comprehensive metrics of performance identify key axes of thermal adaptation in ants

description: How species respond to temperature change depends in large part on their
 physiology. Physiological traits, such as critical thermal limits (CTmax
 and CTmin), provide estimates of thermal performance but may not capture
 the full impacts of temperature on fitness. Rather, thermal performance
 likely depends on a combination of traits—including thermal limits—that
 vary among species. Here we examine how thermal limits correlate with the
 main components that influence fitness in ants. First, we compare how
 temperature affected colony survival and growth in two ant species that
 differ in their responses to warming in the field—Aphaenogaster rudis
 (heat-intolerant) and Temnothorax curvispinosus (heat-tolerant). We then
 extended our study to compare CTmax, thermal requirements of brood, and
 yearly activity season among a broader set of ant species. While thermal
 limits were higher for workers of T. curvispinosus than A. rudis, T.
 curvispinosus colonies also required higher temperatures for survival and
 colony growth. This pattern generalized across 17 ant species, such that
 species whose foragers had a high CTmax also required higher temperatures
 for brood development. Finally, species whose foragers had a high CTmax
 had relatively short activity seasons compared with less heat-tolerant
 species. The relationships between CTmax, thermal requirements of brood,
 and seasonal activity suggest two main strategies for growth and
 development in changing thermal environments: one where ants forage at
 higher temperatures over a short activity season, and another where ants
 forage at lower temperatures for an extended activity season. Where
 species fall on this spectrum may influence a broad range of life-history
 characteristics and aid in explaining the current distributions of ants as
 well as their responses to future climate change.

title: Data from: Bark beetles use a spring-loaded mechanism to produce variable song patterns

description: Many insects vary their song patterns to communicate different messages,
 but the underlying biomechanisms are often poorly understood. Here we
 report on the mechanics of sound production and variation in an
 elytro-tergal stridulator, male Dendroctonus valens bark beetles. Using
 ablation experiments coupled with high-speed video and audio recordings,
 we show that (1) chirps are produced using a stridulatory file on the left
 elytron (forewing) and a protrusion (plectrum) on the seventh abdominal
 segment, (2) chirps are produced by spring stridulation, a
 catch-and-release mechanism whereby the plectrum catches on a file tooth,
 and upon release, springs forward along the file, and (3) variability in
 chirp types is caused by introducing multiple catch and release events
 along the file to create regular interruptions. These results provide
 experimental evidence for the mechanics of elytrotergal stridulation, and
 provide insight into how an insect can incorporate variability into its
 acoustic repertoire using a spring-loaded mechanism.

title: Data from: Do glucocorticoids predict fitness? Linking environmental conditions, corticosterone and reproductive success in the blue tit, Cyanistes caeruleus

description: Glucocorticoids, including corticosterone (CORT), have been suggested to
 provide a physiological link between ecological conditions and fitness.
 Specifically, CORT, which is elevated in response to harsh conditions, is
 predicted to be correlated with reduced fitness. Yet, empirical studies
 show that CORT can be non-significantly, positively and negatively linked
 with fitness. Divergent environmental conditions between years or study
 systems may influence whether CORT is linked to fitness. To test this, we
 monitored free-living blue tits (Cyanistes caeruleus) during breeding over
 3 years. We quantified foraging conditions during brood rearing, and
 examined whether they were correlated with parental baseline CORT and
 reproductive success. We then tested whether CORT predicted fitness.
 Elevated parental CORT was associated with lower temperatures, greater
 rainfall and lower territory-scale oak density. Whereas asynchrony with
 the caterpillar food peak was correlated with reduced nestling mass and
 fledging success, but not parental CORT. Only low temperatures were
 associated with both reduced nestling mass and elevated parental CORT.
 Despite this, parents with elevated CORT had lighter offspring in all
 years. Contrarily, in 2009 parental CORT was positively correlated with
 the number fledged. The absence of a direct link between the foraging
 conditions that reduce nestling quality and elevate parental CORT suggests
 that parental CORT may provide a holistic measure of conditions where
 parents are working harder to meet the demands of developing young. As the
 positive correlation between parental CORT and fledging success differed
 between years, this suggests that contrasting conditions between years can
 influence correlations between parental CORT and fitness. Ultimately, as
 CORT concentrations are intrinsically variable and linked to the prevalent
 conditions, studies that incorporate environmental harshness will improve
 our understanding of evolutionary endocrinology.

title: Data from: Ants at plant wounds – a little-known trophic interaction with evolutionary implications for ant-plant interactions

description: Extrafloral nectaries (EFNs) allow plants to engage in mutualisms with
 ants preventing herbivory in exchange for food. EFNs occur scattered
 through the plant phylogeny and likely evolved independently from
 herbivore-created wounds subsequently visited by ants collecting leaked
 sap. Records of wound-feeding ants are, however, anecdotal. By surveying
 38,000 trees from 40 species, we conduct the first quantitative ecological
 study of this overlooked behavior. Ant-wound interactions were widespread
 (0.5% of tree individuals) and occurred on 23 tree species. Interaction
 networks were opportunistic, closely resembling ant-EFNs networks.
 Fagaceae, a family lacking EFNs, were strongly overrepresented. For
 Fagaceae, ant occurrence at wounds correlated with species-level leaf
 damage, potentially indicating that wounds may attract mutualistic ants,
 supporting the hypothesis of ant-tended wounds as precursors of ant-EFNs
 mutualisms. Given the commonness of herbivore wounds, wound sap as
 steadily available food source might furthermore help to explain the
 overwhelming abundance of ants in (sub)tropical forest canopies.

title: Data from: Increasing the accuracy and precision of relative telomere length estimates by RT qPCR

description: Since attrition of telomeres, DNA caps that protect chromosome integrity,
 is accelerated by various forms of stress, telomere length (TL) has been
 proposed as an indicator of lifetime accumulated stress. In ecological
 studies it has been used to provide insights into aging, life-history
 trade-offs, the costs of reproduction and disease. qPCR is a high
 throughput and cost effective tool to measure relative TL (rTL) that can
 be applied to newly-collected and archived ecological samples. However,
 qPCR is susceptible to error both from the method itself and
 pre-analytical steps. Here, repeatability was assessed overall and
 separately across multiple levels (intra-assay, inter-assay and
 inter-extraction) to elucidate the causes of measurement error, as a step
 towards improving precision. We also tested how accuracy, defined as the
 correlation between the ‘gold standard’ for TL estimation (telomere
 restriction fragment length analysis with in-gel hybridisation), could be
 improved. We find qPCR repeatability (intra- and inter-assay levels) to be
 at similar levels across three common storage media (ethanol,
 Longmire's and Queen's). However, inter-extraction repeatability
 was 50% lower for samples stored in Queen's lysis buffer, indicating
 storage medium can influence precision. Precision as well as accuracy
 could be increased by estimating rTL from multiple qPCR reactions and from
 multiple extractions. Repetition increased statistical power equivalent to
 a 25% (single extraction analysed twice) and 17% (two extractions)
 increase in sample size. Overall, this study identifies novel sources of
 variability in high-throughput telomere quantification and provides
 guidance on sampling strategy design and how to increase rTL precision and
 accuracy.

title: Data from: What have humans done for evolutionary biology? Contributions from genes to populations

description: Many fundamental concepts in evolutionary biology were discovered using
 non-human study systems. Humans are poorly suited to key study designs
 used to advance this field, and are subject to cultural, technological,
 and medical influences often considered to restrict the pertinence of
 human studies to other species and general contexts. Whether studies using
 current and recent human populations provide insights that have broader
 biological relevance in evolutionary biology is, therefore, frequently
 questioned. We first surveyed researchers in evolutionary biology and
 related fields on their opinions regarding whether studies on contemporary
 humans can advance evolutionary biology. Almost all 442 participants
 agreed that humans still evolve, but fewer agreed that this occurs through
 natural selection. Most agreed that human studies made valuable
 contributions to evolutionary biology, although those less exposed to
 human studies expressed more negative views. With a series of examples, we
 discuss strengths and limitations of evolutionary studies on contemporary
 humans. These show that human studies provide fundamental insights into
 evolutionary processes, improve understanding of the biology of many other
 species, and will make valuable contributions to evolutionary biology in
 the future.

title: Data from: Female anoles display less but attack more quickly than males in response to territorial intrusions

description: Fighting to defend a territory can be costly due to the risk of injury
 associated with physical combat. Therefore, many species rely on displays
 that allow individuals to assess one another, avoid escalation, and
 mitigate the costs of physical conflict. Most studies of territorial
 aggression have been conducted in the context of male–male competition,
 and although females of many species are also aggressive, direct
 comparisons of male–male and female–female aggression are rare.
 Consequently, the relative extent to which males and females of
 territorial species use behavioral displays and physical aggression to
 mediate intrasexual competition is generally unknown. To address this
 question, we experimentally introduced same-sex intruders onto the
 territories of male and female brown anole lizards (Anolis sagrei). We
 found that, although males were slightly more likely to attack an intruder
 than were females, males also allowed a greater amount of time to elapse
 before escalating to an attack, relative to females. Males also exhibited
 more aggressive display behaviors (dewlap extensions, push-ups, and
 head-bobs) before engaging in a physical attack. These results are
 consistent with the idea that, due to a potentially greater risk of
 injury, males may attempt to avoid escalating to physical conflict. The
 high rates of attack and low latency to attack that we observed for
 interactions between females also run counter to the general assumption
 that males are categorically more aggressive in territorial, polygynous
 species characterized by extreme male-biased sexual size dimorphism.

title: Data from: Sex-specific effects of inbreeding on reproductive senescence

description: Inbreeding depression plays a significant role in evolutionary biology and
 ecology. Yet, we lack a clear understanding of the fitness consequences of
 inbreeding depression. Studies often focus on short-term effects of
 inbreeding in juvenile offspring whereas inbreeding depression in adult
 traits and the interplay between inbreeding depression and age is rarely
 addressed. Inbreeding depression may increase with age and accelerate the
 decline in reproductive output in ageing individuals (‘reproductive
 senescence’), which could be subject to sex-specific dynamics. We test
 this hypothesis with a longitudinal experimental study in a short-lived
 songbird. Adult inbred and outbred male and female canaries were paired in
 a 2x2 factorial design and survival and annual reproductive performance
 were studied for three years. We found inbreeding depression in female
 egg-laying ability, male fertilization success and survival of both sexes.
 Annual reproductive success of both males and females declined when paired
 with an inbred partner independent of their own inbreeding status. This
 shows that inbreeding can have fitness costs in outbred individuals when
 they mate with an inbred individual. Further, inbred females showed faster
 reproductive senescence than outbred females, confirming that inbreeding
 depression and age can interact to affect fitness. In contrast, there was
 no evidence for an interaction between inbreeding depression and
 reproductive senescence in male fertilization success. Our findings
 highlight the importance of considering sex-specific effects and age to
 determine the full range of fitness consequences of inbreeding and
 demonstrate that inbreeding depression can accelerate reproductive
 senescence.

title: Data from: Plasma pro-atrial natriuretic peptide to indicate fluid balance during cystectomy: a prospective observational study

description: Objectives: During surgery the volume of administered fluid is debated.
 Pro-atrial natriuretic peptide (proANP) is released by atrial distension,
 and we evaluated the relationship between changes in proANP associated
 with perioperative fluid balance. Design: Prospective observational study.
 Setting: One university/tertiary centre. Participants: The study included
 patients who underwent radical cystectomy. Plasma for determination of
 proANP was obtained before surgery, after resection of the bladder, and at
 the end of surgery for 20 robotic-assisted radical cystectomy (RARC) and
 20 open radical cystectomy (ORC) procedures. Results: The blood loss was
 1871 (95% CI 1267 to 2475) vs 589 mL (378 to 801) in the ORC and RARC
 groups (p=0.001), respectively, and fluid balance was positive by 1518 mL
 (1215 to 1821) during ORC, and by 1858 mL (1461 to 2255) during RARC
 (p=0.163). Yet, at the end of ORC, plasma proANP was reduced by 23% (14%
 to 32%, p=0.001), while plasma proANP did not change significantly during
 RARC. Thus, plasma proANP was associated both with the perioperative blood
 loss (r= −0.475 (0.632 to −0.101), p=0.002), and with fluid balance
 (r=0.561 (0.302 to 0.740), p=0.001), indicating that a stable plasma
 proANP required a fluid surplus by 2.4 L (2.0 to 2.7). Conclusions: There
 was a correlation between intraoperative haemorrhage and a decrease in
 plasma proANP and, taking plasma proANP to indicate filling of the heart,
 about 2.5 L surplus volume of lactated Ringer's solution appears to
 maintain cardiac preload during cystectomy.

title: Data from: Generalist insects behave in a jasmonate-dependent manner on their host plants, leaving induced areas quickly and staying longer on distant parts

description: Plants are sessile so have evolved sensitive ways to detect attacking
 herbivores, and sophisticated strategies to effectively defend themselves.
 Insect herbivory induces synthesis of the phytohormone jasmonic acid which
 activates downstream metabolic pathways for various chemical defences such
 as toxins and digestion inhibitors. Insects are also sophisticated
 animals, and many have co-evolved physiological adaptations that negate
 this induced plant defence. Insect behaviour has rarely been studied in
 the context of induced plant defence, although behavioural adaptation to
 induced plant chemistry may allow insects to bypass the host’s defence
 system. By visualizing jasmonate-responsive gene expression within whole
 plants, we uncovered spatial and temporal limits to the systemic spread of
 plant chemical defence following herbivory. By carefully tracking insect
 movement, we found induced changes in plant chemistry were detected by
 generalist Helicoverpa armigera insects which then modified their
 behaviour in response, moving away from induced parts and staying longer
 on un-induced parts of the same plant. This study reveals there are
 plant-wide signals rapidly generated following herbivory that allow
 insects to detect the heterogeneity of plant chemical defences. Some
 insects use these signals to move around the plant, avoiding localised
 sites of induction and staying ahead of induced toxic metabolites.
