title: Data from: Light availability experienced in the field affects ability of following generations to respond to shading in an annual grassland plant

description: For plants competing for light, grasslands represent complex environments.
 Grassland microhabitats vary in the amount of available light and in the
 spatial distribution of patches with full sunlight, light shade and deep
 shade. Plant populations have been shown to adapt to specific competitors
 and shading conditions, but it is an open question how tightly the
 responses of populations to different shading situations are linked to the
 light availability previously experienced in the field. Using maternal
 families collected in grasslands ranging from open to closed canopies, I
 tested the effects of no shading, homogeneous and heterogeneous shade
 created in the glasshouse on trait expression in the annual Erodium
 cicutarium. Heterogeneous shading was simulated by a patchwork of single
 and double layers of light filters lowering the R:FR ratio of transmitted
 light and clear filters simulating gaps. Heterogeneous shading induced a
 stronger shade avoidance response than homogeneous shading, with larger
 leaf length, greater vegetative height and larger specific leaf area. Time
 to first flowering was longer under heterogeneous shading, and plants
 produced less fruits. Populations differed in their time to first
 flowering under the shading treatments, and these differences could be
 traced back to light availability measured in the field. Plants from
 populations with lower light availability showed a postponed date of first
 flowering even if they were not shaded. These differences were
 attributable to plasticity of the maternal families. Across shading
 treatments, plants from low-light environments produced more above-ground
 biomass. Synthesis. This study indicates that there is a close linkage
 between the light availability experienced in the field and the ability of
 following generations to respond to shading. Low average light
 availability experienced in the past seems to induce a trade-off of
 vegetative growth against early flowering, providing the following
 generations with the capacity to overtop neighbours. This capacity is
 utilized especially if plants experience a mixture of gaps and deep shade.

title: Data from: Effects of spring temperatures on the strength of selection on timing of reproduction in a long-distance migratory bird

description: Climate change has differentially affected the timing of seasonal events
 for interacting trophic levels, and this has often led to increased
 selection on seasonal timing. Yet, the environmental variables driving
 this selection have rarely been identified, limiting our ability to
 predict future ecological impacts of climate change. Using a dataset
 spanning 31 years from a natural population of pied flycatchers (Ficedula
 hypoleuca), we show that directional selection on timing of reproduction
 intensified in the first two decades (1980–2000) but weakened during the
 last decade (2001–2010). Against expectation, this pattern could not be
 explained by the temporal variation in the phenological mismatch with food
 abundance. We therefore explored an alternative hypothesis that selection
 on timing was affected by conditions individuals experience when arriving
 in spring at the breeding grounds: arriving early in cold conditions may
 reduce survival. First, we show that in female recruits, spring arrival
 date in the first breeding year correlates positively with hatch date;
 hence, early-hatched individuals experience colder conditions at arrival
 than late-hatched individuals. Second, we show that when temperatures at
 arrival in the recruitment year were high, early-hatched young had a
 higher recruitment probability than when temperatures were low. We
 interpret this as a potential cost of arriving early in colder years, and
 climate warming may have reduced this cost. We thus show that higher
 temperatures in the arrival year of recruits were associated with stronger
 selection for early reproduction in the years these birds were born. As
 arrival temperatures in the beginning of the study increased, but recently
 declined again, directional selection on timing of reproduction showed a
 nonlinear change. We demonstrate that environmental conditions with a lag
 of up to two years can alter selection on phenological traits in natural
 populations, something that has important implications for our
 understanding of how climate can alter patterns of selection in natural
 populations.

title: Data from: Initial genetic diversity enhances population establishment and alters genetic structuring of a newly established Daphnia metapopulation

description: When newly created habitats are initially colonized by genotypes with
 rapid population growth rates, later arriving colonists may be prevented
 from establishing. Although these priority effects have been documented in
 multiple systems, their duration may be influenced by the diversity of the
 founding population. We conducted a large-scale field manipulation to
 investigate how initial clonal diversity influences temporal and landscape
 patterns of genetic structure in a developing metapopulation. Six
 genotypes of obligately asexual Daphnia pulex were stocked alone (no
 clonal diversity) or in combination (‘high’ clonal diversity) into newly
 created experimental woodland ponds. We also measured the population
 growth rate of all clones in the laboratory when raised on higher-quality
 and lower-quality resources. Our predictions were that in the 3 years
 following stocking, clonally diverse populations would be more likely to
 persist than nonclonally diverse populations and exhibit evidence for
 persistent founder effects. We expected that faster growing clones would
 be found in more pools and comprise a greater proportion of individuals
 genotyped from the landscape. Genetic composition, both locally and
 regionally, changed significantly following stocking. Six of 27
 populations exhibited evidence for persistent founder effects, and
 populations stocked with ‘high’ clonal diversity were more likely to
 exhibit these effects than nonclonally diverse populations. Performance in
 the laboratory was not predictive of clonal persistence or overall
 dominance in the field. Hence, we conclude that although laboratory
 estimates of fitness did not fully explain metapopulation genetic
 structure, initial clonal diversity did enhance D. pulex population
 establishment and persistence in this system.

title: Data from: Seeds in motion: genetic assignment and hydrodynamic models demonstrate concordant patterns of seagrass dispersal

description: Movement is fundamental to the ecology and evolutionary dynamics within
 species. Understanding movement through seed dispersal in the marine
 environment can be difficult due to the high spatial and temporal
 variability of ocean currents. We employed a mutually enriching approach
 of population genetic assignment procedures and dispersal predictions from
 a hydrodynamic model to overcome this difficulty and quantify the movement
 of dispersing floating fruit of the temperate seagrass Posidonia australis
 Hook.f. across coastal waters in southwestern Australia. Dispersing fruit
 cohorts were collected from the water surface over two consecutive years
 and seeds were genotyped using microsatellite DNA markers.
 Likelihood-based genetic assignment tests were used to infer the meadow of
 origin for seed cohorts and individuals. A three-dimensional hydrodynamic
 model was coupled with a particle transport model to simulate the movement
 of fruit at the water surface. Floating fruit cohorts were mainly assigned
 genetically to the nearest meadow, but significant genetic differentiation
 between cohort and most-likely meadow of origin suggested a mixed origin.
 This was confirmed by genetic assignment of individual seeds from the same
 cohort to multiple meadows. The hydrodynamic model predicted 60% of fruit
 dispersed within 20 km, but that fruit were physically capable of
 dispersing beyond the study region. Concordance between these two
 independent measures of dispersal provide insight into the role of
 physical transport for long distance dispersal (LDD) of fruit and the
 consequences for spatial genetic structuring of seagrass meadows.

title: Data from: Dynamic disease management in Trachymyrmex fungus-growing ants (Attini: Formicidae)

description: Multipartner mutualisms have potentially complex dynamics, with
 compensatory responses when one partner is lost or relegated to a minor
 role. Fungus-growing ants (Attini) are mutualistic associates of
 basidiomycete fungi and antibiotic-producing actinomycete bacteria; the
 former are attacked by specialized fungi (Escovopsis) and diverse
 generalist microbes. Ants deploy biochemical defenses from bacteria and
 metapleural glands (MGs) and express different behaviors to control
 contaminants. We studied four Trachymyrmex species that differed in
 relative abundance of actinomycetes to understand interactions among
 antimicrobial tactics that are contingent on the nature of infection. MG
 grooming rate and actinomycete abundance were negatively correlated. The
 two species with high MG grooming rates or abundant actinomycetes made
 relatively little use of behavioral defenses. Conversely, the two species
 with relatively modest biochemical defenses relied heavily on behavior.
 Trade-offs suggest that related species can evolutionarily diverge to rely
 on different defense mechanisms against the same threat. Neither bacterial
 symbionts nor MG secretions thus appear to be essential for mounting
 defenses against the specialized pathogen Escovopsis, but reduced
 investment in one of these defense modes tends to increase investment in
 the other.

title: Data from: Specialization and phenological synchrony of plant–pollinator interactions along an altitudinal gradient

description: 1. One of the most noticeable effects of anthropogenic climate change is
 the shift in timing of seasonal events towards earlier occurrence. The
 high degree of variation in species' phenological shifts has raised
 concerns about the temporal decoupling of interspecific interactions, but
 the extent and implications of this effect are largely unknown. In the
 case of plant–pollinator systems, more specialized species are predicted
 to be particularly threatened by phenological decoupling, since they are
 assumed to be less flexible in the choice of interaction partners, but
 until now this hypothesis has not been tested. 2. In this paper, we
 studied phenology and interactions of plant and pollinator communities
 along an altitudinal gradient in the Alps as a model for the possible
 effects of climate change in time. 3. Our results show that even
 relatively specialized pollinators were much more flexible in their use of
 plant species as floral resources than their local flower visitation
 suggested. We found no relationship between local specialization of
 pollinators and the consistency of their visitation patterns across sites,
 and also no relationship between specialization and phenological synchrony
 of pollinators with particular plants. 4. Thus, in contrast to the
 conclusions of a recent simulation study, our results suggest that most
 pollinator species included in this study are not threatened by
 phenological decoupling from specific flowering plants. However, the
 flexibility of many rarely observed pollinator species remains unknown.
 Moreover, our results suggest that specialized flower visitors select
 plant species based on certain floral traits such as the length of the
 nectar holder tube. If that is the case, the observed flexibility of
 plant–pollinator interactions likely depends on a high degree of
 functional redundancy in the plant community, which may not exist in less
 diverse systems.

title: Data from: Effects of forest plantations on the genetic composition of conspecific native Aleppo pine populations

description: Afforestation is a common and widespread management practice throughout
 the world, yet its implications for the genetic diversity of native
 populations are still poorly understood. We examined the effect of Aleppo
 pine (Pinus halepensis) plantations on the genetic composition of nearby
 conspecific native populations. We focused on two native populations in
 Israel with different levels of isolation from the surrounding plantations
 and compared the genetic diversity of naturally established young trees
 within the native populations with that of local native adults, using nine
 nuclear microsatellite markers. We found that the genetic composition of
 the recruits was significantly different from that of local adults in both
 populations, with allelic frequency changes between generations that could
 not be ascribed to random drift, but rather to substantial gene flow from
 the surrounding planted Aleppo pine populations. The more isolated
 population experienced a lower gene flow level (22%) than the less
 isolated population (49%). The genetic divergence between native
 populations at the adult-tree stage (Fst = 0.32) was more than twice as
 high as that of the young trees naturally established around native adults
 (Fst = 0.15). Our findings provide evidence for a rapid genetic
 homogenization process of native populations following the massive
 planting efforts in the last decades. These findings have important
 implications for forest management and nature conservation and constitute
 a warning sign for the risk of translocation of biota for local
 biodiversity.

title: Data from: Inbreeding depression in self-incompatible North American Arabidopsis lyrata: disentangling genomic and S-locus specific genetic load

description: Newly formed selfing lineages may express recessive genetic load and
 suffer inbreeding depression. This can have a genome-wide genetic basis,
 or be due to loci linked to genes under balancing selection. Understanding
 the genetic architecture of inbreeding depression is important in the
 context of the maintenance of self-incompatibility and understanding the
 evolutionary dynamics of S-alleles. We addressed this using North-American
 subspecies of Arabidopsis lyrata. This species is normally
 self-incompatible and outcrossing, but some populations have undergone a
 transition to selfing. The goals of this study were to: (1) quantify the
 strength of inbreeding depression in North-American populations of A.
 lyrata; and (2) disentangle the relative contribution of S-linked genetic
 load compared with overall inbreeding depression. We enforced selfing in
 self-incompatible plants with known S-locus genotype by treatment with
 CO2, and compared the performance of selfed vs outcrossed progeny. We
 found significant inbreeding depression for germination rate (δ=0.33),
 survival rate to 4 weeks (δ=0.45) and early growth (δ=0.07), but not for
 flowering rate. For two out of four S-alleles in our design, we detected
 significant S-linked load reflected by an under-representation of S-locus
 homozygotes in selfed progeny. The presence or absence of S-linked load
 could not be explained by the dominance level of S-alleles. Instead, the
 random nature of the mutation process may explain differences in the
 recessive deleterious load among lineages.

title: Data from: Impact of disease on diversity and productivity of plant populations

description: Experiments were conducted on the role of intra- and inter-genotypic
 competition in ecological processes operating at the population scale in
 diseased plant populations. Combinations of Arabidopsis thaliana genotypes
 showing variation for phenotypic traits relating to competitive ability
 and pathogen compatibility were infected with the oomycete
 Hyaloperonospora arabidopsidis and Turnip yellows virus in separate
 experiments. Plant fitness and competitive ability were estimated from
 phenotypic measurements. Pathogen-induced reduction in competitive ability
 for susceptible genotypes increased the competitive ability of resistant
 genotypes, resulting in maintenance of yield via competitive release. The
 two diseases had different effects on competitive interactions between
 plants. In experiments involving the oomycete, the highest yields were
 produced by mixtures of two weakly competing genotypes. The Arabidopsis
 model system has elucidated the ecological processes by which compensatory
 competitive interactions can increase the buffering capacity of plant
 populations under pathogen attack. Highly competitive genotypes may not
 maximize the productivity of the population as a whole, as they may
 over-yield at the expense of less competitive, more productive genotypes.
 The specific outcomes of competitive interactions cannot be generalized
 because they depend on the disease and the host genotypes.

title: Data from: Paternity analysis of wood turtles (Glyptemys insculpta) reveals complex mating patterns

description: Mating system characteristics are of great importance as they may
 influence male and female reproductive success and reproductive isolation.
 The wood turtle (Glyptemys insculpta) is a terrestrial freshwater species
 listed as endangered by the International Union for Conservation of
 Nature. Considering its conservation status and the paucity of information
 currently available on parentage relationship for the species, we
 performed a microsatellite analysis to study the mating system of wood
 turtles in the Shawinigan River (Québec). We sampled 38 clutches over two
 years (14 in 2006 and 24 in 2007), for a total of 248 offspring genotyped
 with seven microsatellite loci. The reconstructed genotypes of the fathers
 revealed that reproductive success in the sampled clutches varied greatly
 between males and are positively correlated with the number of mates and
 clutches sired. Frequency of multiple paternity was estimated at 37%
 through a consensus of three different estimation methods. Positive
 correlation was observed between the genetic diversity of clutches and the
 number of fathers. Repeat paternity, however, was observed in 88% of the
 clutches by the same female in successive years, which suggests either a
 frequent use of sperm storage, or re-mating with the same partner in
 successive years.

title: Data from: Model and test in a fungus of the probability that beneficial mutations survive drift

description: Determining the probability of fixation of beneficial mutations is
 critically important for building predictive models of adaptive evolution.
 Despite considerable theoretical work, models of fixation probability have
 stood untested for nearly a century. However, recent advances in
 experimental and theoretical techniques permit the development of models
 with testable predictions. We developed a new model for the probability of
 surviving genetic drift, a major component of fixation probability, for
 novel beneficial mutations in the fungus Aspergillus nidulans, based on
 the life-history characteristics of its colony growth on a solid surface.
 We tested the model by measuring the probability of surviving drift in 11
 adapted strains introduced into wild-type populations of different
 densities. We found that the probability of surviving drift increased with
 mutant invasion fitness, and decreased with wild-type density, as
 expected. The model accurately predicted the survival probability for the
 majority of mutants, yielding one of the first direct tests of the
 extinction probability of beneficial mutations.
