title: Data from: Trait anticipatory pleasure predicts effort expenditure for reward

description: Research in motivation and emotion has been increasingly influenced by the
 perspective that processes underpinning the motivated approach of
 rewarding goals are distinct from those underpinning enjoyment during
 reward consummation. This distinction recently inspired the construction
 of the Temporal Experience of Pleasure Scale (TEPS), a self-report measure
 that distinguishes trait anticipatory pleasure (pre-reward feelings of
 desire) from consummatory pleasure (feelings of enjoyment and
 gratification upon reward attainment). In a university community sample (N
 = 97), we examined the TEPS subscales as predictors of (1) the willingness
 to expend effort for monetary rewards, and (2) affective responses to a
 pleasant mood induction procedure. Results showed that both anticipatory
 pleasure and a well-known trait measure of reward motivation predicted
 effort-expenditure for rewards when the probability of being rewarded was
 relatively low. Against expectations, consummatory pleasure was unrelated
 to induced pleasant affect. Taken together, our findings provide support
 for the validity of the TEPS anticipatory pleasure scale, but not the
 consummatory pleasure scale.

title: Data from: Sex ratio and gamete size across eastern North America in Dictyostelium discoideum, a social amoeba with three sexes

description: Theory indicates that numbers of mating types should tend towards infinity
 or remain at two. The social amoeba, Dictyostelium discoideum, however,
 has three mating types. It is therefore a mystery how this species has
 broken the threshold of two mating types, but has not increased towards a
 much higher number. Frequency dependent selection on rare types in
 combination with isogamy, a form of reproduction involving gametes similar
 in size, could explain the evolution of multiple mating types in this
 system. Other factors, such as drift, may be preventing the evolution of
 more than three. We first looked for evidence of isogamy by measuring
 gamete size associated with each type. We found no evidence of size
 dissimilarities between gametes. We then looked for evidence of balancing
 selection, by examining mating type distributions in natural populations
 and comparing genetic differentiation at the mating type locus to that at
 more neutral loci. We found that mating type frequency varied among the
 three populations we examined, with only one of the three showing an even
 sex ratio, which does not support balancing selection. However, we found
 more population structure at neutral loci than the mating type locus,
 suggesting that the three mating types are indeed maintained at
 intermediate frequencies by balancing selection. Overall, the data are
 consistent with balancing selection acting on D. discoideum mating types,
 but with a sufficiently weak rare sex advantage to allow for drift, a
 potential explanation for why these amoebae have only three mating types.

title: Data from: Genetic co-structure in a meta-community under threat of habitat fragmentation

description: Habitat fragmentation increasingly threatens the services provided by
 natural communities and ecosystem worldwide. An understanding of the
 eco-evolutionary processes underlying fragmentation-compromised
 communities in natural settings is lacking, yet critical to realistic and
 sustainable conservation. Through integrating the multivariate genetic,
 biotic and abiotic facets of a natural community module experiencing
 various degrees of habitat fragmentation, we provide unique insights into
 the processes underlying community functioning in real, natural
 conditions. The focal community module comprises a parasitic butterfly of
 conservation concern, and its two obligatory host species, a plant and an
 ant. We show that both historical dispersal and ongoing habitat
 fragmentation shape population genetic diversity of the butterfly
 Phengaris alcon and its most limited host species (the plant Gentiana
 pneumonanthe). Genetic structure of the individual species was strongly
 driven by geographical structure, altitude and landscape connectivity.
 Strikingly, however, was the strong degree of genetic co-structure among
 the three species that could not be explained by the spatial variables
 under study. This finding suggests that factors other than spatial
 configuration, including co-evolutionary dynamics and shared dispersal
 pathways, cause parallel genetic structure among interacting species.
 While the exact contribution of coevolution and shared dispersal routes on
 the genetic variation within and among communities deserves further
 attention, our findings demonstrate a considerable degree of genetic
 parallelism in natural meta-communities. The significant effect of
 landscape connectivity on the genetic diversity and structure of the
 butterfly also suggests that habitat fragmentation may threaten the
 functioning of the community module on the long run.

title: Data from: Comparison of the genetic determinism of two key phenological traits, flowering and maturity dates, in three Prunus species: peach, apricot and sweet cherry

description: The present study investigates the genetic determinism of flowering and
 maturity dates, two traits highly affected by global climate change.
 Flowering and maturity dates were evaluated on five progenies from three
 Prunus species, peach, apricot and sweet cherry, during three to eight
 years. Quantitative trait locus (QTL) detection was performed separately
 for each year and also by integrating data from all years together. High
 heritability estimates were obtained for flowering and maturity dates.
 Several QTLs for flowering and maturity dates were highly stable, detected
 each year of evaluation, suggesting that they were not affected by
 climatic variations. For flowering date, major QTLs were detected on
 linkage groups (LG) 4 for apricot and sweet cherry and on LG6 for peach.
 QTLs were identified on LG2, LG3, LG4 and LG7 for the three species. For
 maturity date, a major QTL was detected on LG4 in the three species. Using
 the peach genome sequence data, candidate genes underlying the major QTLs
 on LG4 and LG6 were investigated and key genes were identified. Our
 results provide a basis for the identification of genes involved in
 flowering and maturity dates that could be used to develop cultivar
 ideotypes adapted to future climatic conditions.

title: Data from: Consequences of breeding system for body condition and survival throughout the annual cycle of tidal marsh sparrows

description: An individual’s body condition and probability of survival can change
 throughout the annual cycle, based on the combined effects of many
 factors, including reproductive investment during breeding, colder
 temperatures during winter, and elevated risks during migration. We
 evaluated body condition and survival during breeding and non-breeding
 periods in two closely related species with notably different reproductive
 systems. Male and female saltmarsh sparrows (Ammodramus caudacutus)
 represent extremes in parental care: males perform none, leaving females
 to do everything from build nests to care for fledglings. In contrast,
 male and female seaside sparrows (A. maritimus) have bi-parental care and
 similar levels of reproductive investment, intermediate between male and
 female saltmarsh sparrows. Our results are consistent with the idea that
 females experience non-lethal effects of reproduction, and that
 differences between the breeding season and winter affect condition. In
 both species, females had lower scaled mass index (SMI) values than males
 during both breeding and non-breeding seasons, and female saltmarsh
 sparrows had lower SMI values than female seaside sparrows. Females
 carried more fat than males during the breeding season, and female, but
 not male, fat and muscle scores decreased over time, which is consistent
 with the adaptive mass hypothesis. In winter, all groups carried more fat
 and had higher muscle scores than when breeding, despite having lower SMI
 scores. Although we observed variation in body condition, within-season
 survival was uniformly high in both seasons, suggesting that sex, species,
 season, body size, and body condition have little impacts on within season
 survival. Comparisons with previously-published estimates of annual adult
 survival suggest that most mortality occurs during migration, even in
 these short-distance migrants. The importance of considering multiple
 aspects of body condition, multiple seasons, and difficult-to-monitor
 events, such as migration, should not be ignored when thinking about the
 events and processes that cumulatively determine population dynamics.

title: Data from: Plant competitive interactions and invasiveness: searching for the effects of phylogenetic relatedness and origin on competition intensity

description: The invasion success of introduced plants is frequently explained as a
 result of competitive interactions with native flora. Although previous
 theory and experiments have shown that plants are largely equivalent in
 their competitive effects on each other, competitive non-equivalence is
 hypothesized to occur in interactions between native and invasive species.
 Small overlap in resource use with unrelated natives, improved
 competitiveness and production of novel allelochemicals are all believed
 to contribute to the invasiveness of introduced species. I tested all
 three assumptions in a common-garden experiment by examining the effect of
 plant origin and relatedness on competition intensity. Competitive
 interactions were explored within 12 triplets, each consisting of an
 invasive species, a native congeneric (or confamilial) species and a
 native heterogeneric species that are likely to interact in the field.
 Plants were grown in pots alone or in pairs and in the absence or presence
 of activated carbon to control for allelopathy. I found that competition
 intensity was not influenced by the relatedness or origin of competing
 neighbors. Although some exotic species may benefit in competition from
 larger size and species-specific effects, none of the three mechanisms
 investigated is likely to be a principal driver of their invasiveness.

title: Data from: Genotypic diversity in root-endophytic fungi reflects efficient dispersal and environmental adaptation

description: Studying community structure and dynamics of plant-associated fungi is the
 basis for unravelling their interactions with hosts and ecosystem
 functions. A recent sampling revealed that only a few fungal groups, as
 defined by internal transcribed spacer region (ITS) sequence similarity,
 dominate culturable root endophytic communities of nonmycorrhizal
 Microthlaspi spp. plants across Europe. Strains of these fungi display a
 broad phenotypic and functional diversity, which suggests a genetic
 variability masked by ITS clustering into operational taxonomic units
 (OTUs). The aims of this study were to identify how genetic similarity
 patterns of these fungi change across environments and to evaluate their
 ability to disperse and adapt to ecological conditions. A first ITS-based
 haplotype analysis of ten widespread OTUs mostly showed a low to moderate
 genotypic differentiation, with the exception of a group identified as
 Cadophora sp. that was highly diverse. A multilocus phylogeny based on
 additional genetic loci (partial translation elongation factor 1α,
 beta-tubulin and actin) and amplified fragment length polymorphism
 profiling of 185 strains representative of the five dominant OTUs revealed
 a weak association of genetic differences with geography and environmental
 conditions, including bioclimatic and soil factors. Our findings suggest
 that dominant culturable root endophytic fungi have efficient dispersal
 capabilities, and that their distribution is little affected by
 environmental filtering. Other processes, such as inter- and intraspecific
 biotic interactions, may be more important for the local assembly of their
 communities.

title: Data from: Anthropogenic harvesting pressure and changes in life history: insights from a rocky intertidal limpet

description: The importance of large breeding individuals for maintaining the health of
 marine fish and invertebrate populations has long been recognized.
 Unfortunately, decades of human harvesting that preferentially remove
 larger individuals have led to drastic reductions in body sizes of many of
 these species. Such size-selective harvesting is particularly worrisome
 for sequentially hermaphroditic species where the larger size classes are
 composed primarily of one sex. Whether these species can maintain stable
 sex ratios under sustained harvesting pressure depends on the level of
 plasticity of their life history traits. Here, we show that populations of
 a marine limpet (Lottia gigantea) can adjust a fundamental aspect of their
 life history (the timing of sex change) when subjected to size-selective
 harvesting. As predicted by theoretical models, individuals from harvested
 populations change sex at smaller sizes and grow at slower rates compared
 to individuals from protected populations. In addition, the relative size
 at which the change from male to female occurs remains constant (~0.75;
 size at sex change / maximum size) across populations, regardless of
 harvesting pressure. Our results show that population-level demographic
 and life history data, in conjunction with existing theory, can be
 sufficient to predict the responses of sequential hermaphrodites to
 harvesting pressure. Furthermore, they suggest such species can
 potentially adapt to size-selective harvesting.

title: Data from: Insulin-like growth factor 1 and life-history evolution of passerine birds

description: 1. Natural selection has generated a diversity of ways in which
 vertebrates allocate their resources between fundamental life-history
 traits. The availability of possible evolutionary trajectories of these
 traits is limited by various genetic, physiological, and phylogenetic
 constraints. This causes trade-offs due to shared resource pools for, or
 genetic linkage of, competing traits. The majority of these trade-offs are
 mediated by hormones and create the variability of phenotypes that can be
 observed in nature. 2. Insulin-like growth factor 1 (IGF-1) is an
 evolutionarily conserved peptide, which has been shown to be essential in
 the regulation of body size, the pattern of reproductive investment and
 lifespan across a broad taxonomic range of model species in laboratory and
 domesticated conditions. However, studies addressing corresponding
 evolutionary hypotheses on a broader scale and in free-living vertebrates
 are very rare. 3. In this phylogenetic comparative study on free-living
 passerines (Passeriformes), we explore the way in which plasma IGF-1
 levels underlie the evolution of body size and demographic fitness
 correlates (clutch size, egg weight, lifespan). 4. We showed firstly that
 IGF-1 levels were positively associated with the body size of passerines,
 although smaller birds had larger IGF-1-mediated investment into building
 up their body faster. IGF-1 levels were negatively associated with
 lifespan of passerines, and more so in birds with smaller body weight.
 Finally, IGF-1 levels were negatively associated with clutch size in
 heavier species, and positively associated with egg weight in species with
 higher body weight and longer duration of parental care. The pattern was
 opposite in species with smaller body weight and shorter duration of
 parental care. 5. The described evolutionary framework indicates that
 variation in IGF-1 levels can be regarded as an important mechanism that
 may underlie life-history evolution in passerines. IGF-1 could act as a
 physiological link mediating the inter-regulatory
 growth–reproduction–lifespan “life-history triangle” on the pace-of-life
 continuum. Interestingly, body weight and investment into parental care
 have likely imposed a constraining effect on the IGF-1-mediated
 co-evolution of demographic fitness traits, such as lifespan or
 reproductive investment. This has limited the availability of adaptive
 pathways via which those traits could evolve as passerines diversified.

title: Data from: Lower haematocrit, haemoglobin and red blood cell number in zebra finches acclimated to cold compared to thermoneutral temperature

description: Thermoregulation constitutes an important share of the energy budget of
 endotherms. Elevated thermoregulatory requirements must be met by oxygen
 supply through the blood, as heat is produced mainly via aerobic
 processes. In contrast to mammal studies, it remains unclear whether
 elevated thermoregulatory needs are followed by changes in haematological
 variables in birds. We investigated haematocrit (HCT), haemoglobin content
 per volume of blood (HGB), number of red blood cells (RBC), and size of
 the erythrocytes (RBC) in zebra finches (Taeniopygia guttata) acclimated
 to either cold or thermoneutral ambient temperatures under laboratory
 conditions. Seventy-nine females were maintained for six weeks either in
 cold (T = + 12 °C) or thermoneutral (T = + 32 °C) ambient temperature
 prior to blood collection. On average, HGB, HCT and RBC were significantly
 lower by about 10% in cold acclimated compared to thermoneutral acclimated
 birds. Only RBC was not different between the two acclimation
 temperatures. Mean HCT, one of the most commonly measured haematological
 variable for example was 53 ± 0.9 % (LSM ± s.e.m) in thermoneutral and 49
 ± 0.8 % (LSM ± s.e.m) in cold acclimated zebra finches. On first sight,
 the observed lower values for three out of the four determined
 haematological variables in response to acclimation to cold question
 oxygen supply to be indeed a limiting factor for heat production. However,
 higher demands of oxygen supply due to increased thermoregulation in birds
 may instead require specific optimisation of blood viscosity and
 modulation by other cardiovascular properties. Nucleated red blood cells
 in birds may pose different strain on blood viscosity compared to
 non-nucleated mammalian erythrocytes and explain the contrasting response
 in haematological variables to temperature acclimation between birds and
 mammals.

title: Data from: Wheat nutrient response functions for the East Africa highlands

description: Wheat (Triticum æstivum L.) is an important East Africa highland crop but
 yields are low. Information is scarce for optimization of fertilizer use.
 Research was conducted to determine yield response functions for N, P and
 K, and to diagnose Mg–S–Zn–B deficiencies. The average grain yield
 increase in Rwanda due to N application was 1.5 Mg ha−1 with a mean
 economically optimal rate (EOR) of 68 kg ha−1 N. In Kenya and Tanzania,
 yield was increased by 29% with EOR N for two SY but unaffected by N rate
 for four other SY which on average had 50% of the soil organic C (SOC) as
 the N-responsive SY. Yield was increased, on average, with application of
 P and K by 0.47 and 0.23 Mg ha−1, respectively, at EOR in Rwanda but
 effects were inconsistent for other SY where soil test K was higher than
 in Rwanda. Application of Mg–S–Zn–B resulted in 0.46 Mg ha−1 more yield in
 Rwanda but did not affect yield at other SY where the average soil test
 values for these nutrients was 35% higher than in Rwanda. If the
 financially constrained farmer opts to apply the affordable fertilizer to
 twice as much land at 50% EOR compared with 100% EOR, the mean yield
 increase is reduced by 27% but production and PCR are increased by 43 and
 72%, respectively. Nutrient effects were relatively consistent and
 positive in Rwanda, but less and less inconsistent elsewhere with
 generally less SOC, more K–Mg–S–Zn–B availability, and often lower yields.
