title: Data from: Genetic structure of introduced American mink (Neovison vison) in Patagonia: colonisation insights and implications for control and management strategies

description: Context: Biological invasions have caused dramatic changes in native
 biodiversity and ecosystem function. Studies of genetic variation and
 evolutionary changes are useful for understanding population dynamics
 during biological invasions, and shed light on management, prevention and
 restoration strategies. Aims: This study aimed to investigate the
 structure and genetic variability of American mink (Neovison vison), an
 invasive species in southern South America, introduced for fur farming in
 the 1930s. Methods: Samples from 153 mink were obtained from 12 locations
 in southern Chile to sequence the mitochondrial DNA (mtDNA) control region
 and to genotype 11 polymorphic microsatellite loci. Key results: The
 highest mtDNA diversity was detected in Puerto Cisnes, suggesting multiple
 introductions and/or the most probable area where mink was first
 introduced. The latter is also supported by microsatellite data, because a
 high percentage of individuals from different locations were assigned to
 this location. All other locations showed low or no mtDNA diversity,
 possibly due to founder effect. The results also indicate marked
 population structure, with three genetic clusters coincident with the main
 historical introduction points, with low dispersal among them.
 Conclusions: The results suggest that control strategies for American mink
 in southern Chile should be concentrated on these three genetically
 differentiated management units, and particularly on source populations
 and locations with low effective population size and restricted
 connectivity. Implications: Genetic approaches have been used for the
 management of numerous alien species worldwide. Recommendations delivered
 here for American mink control could also be implemented in other regions
 and for other invasive species with similar genetic diversity distribution
 and connectivity.

title: Data from: A facultative endosymbiont in aphids can provide diverse ecological benefits

description: Ecologically important traits of insects are often affected by facultative
 bacterial endosymbionts. This is best studied in the pea aphid
 Acyrthosiphon pisum, which is frequently infected by one or more of eight
 facultative symbiont species. Many of these symbiont species have been
 shown to provide one ecological benefit, but we have little understanding
 of the range of effects that a single strain can have. Here, we describe
 the phenotypes conferred by three strains of the recently discovered
 bacterium known as X-type (Enterobacteriaceae), each in their original
 aphid genotype which also carries a Spiroplasma symbiont. All comparisons
 are made between aphids at that are coinfected with Spiroplasma and X-type
 and aphids of the same genotype that harbor only Spiroplasma. We show that
 in all cases, infection with X-type protects aphids from the lethal fungal
 pathogen Pandora neoaphidis, and in two cases resistance to the parasitoid
 Aphidius ervi also increases. X-type can additionally affect aphid stress
 responses – the presence of X-type increased reproduction after the aphids
 were heat stressed. Two of the three strains of X-type are able to provide
 all of these benefits. Under benign conditions the aphids tended to suffer
 from reduced fecundity when harboring X-type, a mechanism that might
 maintain intermediate frequencies in field populations. These findings
 highlight that a single strain of a facultative endosymbiont has the
 potential to provide diverse benefits to its aphid host.

title: Data from: The interplay among acorn abundance and rodent behavior drives the spatial pattern of seedling recruitment in mature Mediterranean oak forests

description: The patterns of seedling recruitment in animal-dispersed plants result
 from the interactions among environmental and behavioral variables.
 However, we know little on the contribution and combined effect of both
 kinds of variables. We designed a field study to assess the interplay
 between environment (vegetation structure, seed abundance, rodent
 abundance) and behavior (seed dispersal and predation by rodents, and
 rooting by wild boars), and their contribution to the spatial patterns of
 seedling recruitment in a Mediterranean mixed-oak forest. In a spatially
 explicit design, we monitored intensively all environmental and behavioral
 variables in fixed points at a small spatial scale from autumn to spring,
 as well as seedling emergence and survival. Our results revealed that the
 spatial patterns of seedling emergence were strongly related to acorn
 availability on the ground, but not by a facilitationeffect of vegetation
 cover. Rodents changed seed shadows generated by mother trees by
 dispersing most seeds from shrubby to open areas, but the spatial patterns
 of acorn dispersal/predation had no direct effect on recruitment. By
 contrast, rodents had a strong impact on recruitment as pilferers of
 cached seeds. Rooting by wild boars also reduced recruitment by reducing
 seed abundance, but also by changing rodent’s behavior towards higher
 consumption of acorns in situ. Hence, seed abundance and the foraging
 behavior of scatter-hoarding rodents and wild boars are driving the
 spatial patterns of seedling recruitment in this mature oak forest, rather
 than vegetation features. The contribution of vegetation to seedling
 recruitment (e.g. facilitation by shrubs) may be context dependent, having
 a little role in closed forests, or being overridden by directed seed
 dispersal from shrubby to open areas. We warn about the need of using
 broad approaches that consider the combined action of environment and
 behavior to improve our knowledge on the dynamics of natural regeneration
 in forests.

title: Data from: Low recruitment of native trees in a deciduous forest associated with Japanese barberry (Berberis thunbergii) invasion

description: Invasive plants may dramatically impact forest ecosystems by establishing
 dense populations and suppressing the recruitment of native tree species.
 One invasive shrub currently spreading throughout eastern deciduous
 forests of North America, Japanese barberry (Berberis thunbergii DC), may
 be limiting tree recruitment in stands where it invades. Once established,
 B. thunbergii becomes densely populated within forest understories and
 suppresses native plants by competing for limited resources, altering soil
 conditions, and changing the understory microclimate. To quantify native
 seedling inhibition caused by B. thunbergii invasion, we conducted an
 observational study on seedling abundance within forest plots that were
 either invaded or not invaded by B. thunbergii and used survey data to
 generate Bayesian models of native seedling densities along gradients of
 increasing B. thunbergii stem counts and aboveground plant dry mass. Model
 outputs predicted that B. thunbergii–invaded plots had 82% lower seedling
 densities compared with uninvaded plots. Native tree seedling densities
 were very low even in areas with moderate B. thunbergii density,
 suggesting that reduced tree seedling densities are observed even at low
 densities of invasion. Our findings indicate that forests invaded with B.
 thunbergii harbor substantially lower densities of native tree seedlings,
 with potentially significant long-term consequences for forest ecological
 integrity, biodiversity, and ecosystem services.

title: Data from: Whether larval amphibians school does not affect the parasite aggregation rule: testing the effects of host spatial heterogeneity in field and experimental studies

description: Almost all macroparasites show over-dispersed infections within natural
 host populations such that most parasites are distributed among a few
 heavily-infected individuals. Despite the importance of parasite
 aggregation for understanding system stability, the potential for
 population regulation, and super-spreading events, many questions persist
 about its underlying drivers. Theoretically, aggregation results from
 heterogeneity in host exposure, resistance, and tolerance. However, few
 studies have examined how host spatial arrangement – which likely affects
 both parasite encounter and density-dependent interactions – influences
 infection and dispersion, representing a critical gap in our current
 knowledge regarding the possible drivers of parasite aggregation. Using
 field data from over 165 ponds and 8,000 hosts, we evaluated how the
 spatial clustering of amphibian larvae within ponds 1) varied among
 different amphibian species, and 2), affected the distribution of
 parasites within the host population using Taylor’s Power Law. A
 complementary mesocosm experiment used field-guided manipulations of the
 spatial arrangement of larval amphibians to create a gradient in host
 clustering while controlling host density, thereby testing for spatial
 effects on both infection success and aggregation by three different
 trematode species. Our field data indicated that larval amphibians
 exhibited significant spatial clustering that was well captured by
 Taylor’s Power Law (R2 0.92 to 0.97 for different host species), but the
 residual variation only weakly correlated with observed patterns of
 trematode parasite over-dispersion. Correspondingly, experimental
 manipulation of host clustering had no effects on parasite infection
 success or the degree of parasite aggregation among cages or mesocosms.
 Given the importance of parasite over-dispersion for host populations and
 disease dynamics, we advocate for further investigations of host and
 parasite spatial aggregation, particularly studies that incorporate and/or
 control for heterogeneity in exposure and susceptibility.

title: Data from: An empirical test for a zone of canalization in thermal reaction norms

description: Theoretical models on the evolution of phenotypic plasticity predict a
 zone of canalization where reaction norms cross and genetic variation is
 minimized in the environment a population most frequently encounter.
 Empirical tests of this prediction are largely missing, in particular for
 life-history traits. We addressed this prediction by quantifying thermal
 reaction norms of three life-history traits (somatic growth rate, age and
 size at maturation) of a Norwegian population of Daphnia magna and testing
 for the occurrence of an intermediate temperature (Tm) at which genetic
 variance in the traits is minimized. Size at maturation changed relatively
 little with temperature compared to the other traits, and there was no
 genetic variance in the shape of the reaction norm. Consequently, age at
 maturation and somatic growth rate were strongly negatively correlated.
 Both traits showed a strong genotype-environment interaction and the
 estimated Tm was 14°C for both age at maturation and growth rate. This
 value of Tm corresponds well with mean summer temperatures experienced by
 the population and suggests that the population has evolved under
 stabilizing selection in temperatures that fluctuate around this mean
 temperature. These results suggest local adaptation to temperature in the
 studied population and allow predicting evolutionary trajectories of
 thermal reaction norms under changing thermal regimes.

title: Data from: Trophic consequences of introduced species: comparative impacts of increased inter-specific versus intra-specific competitive interactions

description: 1. Invasive species can cause substantial ecological impacts on native
 biodiversity. Whilst ecological theory attempts to explain the processes
 involved in the trophic integration of invaders into native food webs and
 their competitive impacts on resident species, results are equivocal. In
 addition, quantifying the relative strength of impacts from non-native
 species (inter-specific competition) versus the release of native
 conspecifics (intra-specific competition) is important but rarely
 completed. 2. Two model non-native fishes, the globally invasive Cyprinus
 carpio and Carassius auratus, and the model native fish Tinca tinca, were
 used in a pond experiment to test how increased intra- and inter-specific
 competition influenced trophic niches and somatic growth rates. This was
 complemented by samples collected from three natural fish communities
 where the model fishes were present. The isotopic niche, calculated using
 stable isotope data, represented the trophic niche. 3. The pond experiment
 used additive and substitutive treatments to quantify the trophic niche
 variation that resulted from intra- and inter-specific competitive
 interactions. Although the trophic niche sizes of the model species were
 not significantly altered by any competitive treatment, they all resulted
 in patterns of inter-specific niche divergence. Increased inter-specific
 competition caused the trophic niche of T. tinca to shift to a
 significantly higher trophic position, whereas intra-specific competition
 caused its position to shift towards elevated δ13C. These patterns were
 independent of impacts on fish growth rates, which were only significantly
 altered when inter-specific competition was elevated. 4. In the natural
 fish communities, patterns of trophic niche partitioning between the model
 fishes was evident, with no niche sharing. Comparison of these results
 with those of the experiment revealed the most similar results between the
 two approaches were for the niche partitioning between sympatric T. tinca
 and C. carpio. 5. These results indicate that trophic niche divergence
 facilitates the integration of introduced species into food webs, but
 there are differences in how this manifests between introductions that
 increase inter- and intra-specific competition. In entirety, these results
 suggest that the initial ecological response to an introduction appears to
 be a trophic re-organisation of the food web that minimises the trophic
 interactions between competing species.

title: Data from: An insect ecosystem engineer alleviates drought stress in plants without increasing plant susceptibility to an above-ground herbivore

description: Climate change models predict more extreme rainfall patterns, ranging from
 droughts to deluges, which will inevitably affect primary productivity in
 many terrestrial ecosystems. Insects within the ecosystem, living above-
 and below-ground, may modify plant responses to water stress. For example,
 some functional groups improve soil conditions via resource provision,
 potentially alleviating water stress. Enhanced resource provision may,
 however, render plants more susceptible to herbivores and negate
 beneficial effects. Using a model system, we tested how plants (Brassica
 oleracea) responded to drought, ambient and increased precipitation
 scenarios when interacting with both a soil conditioning ecosystem
 engineer (dung beetles; Bubas bison) and an above-ground herbivore, the
 major crop pest diamondback moth (Plutella xylostella). Dung beetles
 enhanced soil water retention by 10% and promoted growth in plants
 subjected to drought by 280%, relieving the impacts of water stress on
 plants. Under drought conditions, plants grown with dung beetles had c.
 30% more leaves and were over twice as tall as those without dung beetles.
 Dung beetles produced a 2·7-fold increase in nitrogen content and more
 than a threefold increase in carbon content of the shoots, though shoot
 concentrations of nitrogen and carbon were unchanged. Carbon
 concentrations in roots, however, were increased by dung beetles under
 both ambient and increased precipitation regimes. Increased precipitation
 reduced root and shoot nitrogen concentrations by 16% and 30%, relative to
 plants under ambient regimes, respectively, most likely due to dilution
 effects of increased plant growth under increased precipitation. Soil
 carbon and nitrogen concentrations were largely unaffected. While dung
 beetles enhanced plant growth and nitrogen content in plants experiencing
 drought, the anticipated increase in plant suitability to herbivores did
 not arise, possibly because shoot nitrogen concentrations and C:N ratio
 were unaffected. To our knowledge, this is the first report of an insect
 ecosystem engineer alleviating the effects of predicted drought events on
 plants via physical manipulation of the soil matrix. Moreover, their
 effects did not change plant suitability to an above-ground herbivore,
 pointing to potential beneficial role for insect ecosystem engineers in
 climate change adaptation and crop protection.

title: Data from: Mouth dimorphism in scale-eating cichlid fish from Lake Tanganyika advances individual fitness

description: Random asymmetry, that is the co-existence of left- and right-sided (or
 -handed) individuals within a population, is a particular case of natural
 variation; what triggers and maintains such dimorphisms remains unknown in
 most cases. Here, we report a field-based cage experiment in the
 scale-eating Tanganyikan cichlid Perissodus microlepis (Boulenger, 1898),
 which occurs in two morphs in nature: left-skewed and right-skewed
 individuals with respect to mouth orientation. Using underwater cages
 stocked with scale-eaters and natural prey fish, we first confirm that,
 under semi-natural conditions, left-skewed scale-eaters preferentially
 attack the right flank of their prey, whereas right-skewed individuals
 feed predominantly from the left side. We then demonstrate that
 scale-eaters have a higher probability for successful attacks when kept in
 dimorphic experimental populations (left- AND right-skewed morphs
 together) as compared to monomorphic populations (left- OR right-skewed
 morphs), most likely because prey fishes fail to accustom to strikes from
 both sides. The significantly increased probability for attacks appears to
 be the selective agent responsible for the evolution and maintenance of
 mouth dimorphism in P. microlepis, lending further support to the
 hypothesis that negative frequency-dependent selection is the stabilizing
 force balancing the mouth dimorphism at quasi-equal ratios in scale-eating
 cichlids.
