title: Data from: An experimental extreme drought reduces the likelihood of species to coexist despite increasing intransitivity in competitive networks

description: Very little is known about how variation in environmental conditions
 alters the strength and the structure of competitive networks and what are
 the consequences of this for species coexistence. We performed a
 competition experiment with 10 annual plant species to parameterise a
 population model describing species’ dynamics according to their vital
 rates and pairwise competitive coefficients. Seeds from all species were
 sown under two different climatic scenarios: (1) right before the first
 major storm of the growing season and (2) after an imposed fall drought of
 2 months simulating an extreme climatic event of intense aridity. Species’
 demography and competitive responses were used to estimate pairwise
 stabilising niche differences and average fitness differences. In
 addition, we used tools from network theory to characterise the structure
 of multispecies competition from the determinants of species coexistence.
 Specifically, we evaluated changes in competitive dominance between
 species pairs, and the prevalence of intransitive competitive
 relationships for 120 triplets between these two climatic events. The
 experimental extreme event significantly reduced fitness differences
 between species pairs. Such an equalising mechanism promotes coexistence.
 However, niche differences were also reduced in such a way that the number
 of species pairs whose niche differences overcame their fitness
 differences was reduced from six to two. Contrary to our expectations, the
 extreme event did not increase the hierarchy of competitive dominance.
 Instead, and depending on the technique used, the prevalence of
 intransitivity remained marginally similar (17% to 22%) or significantly
 increased from 19.4% to 29.8%. This pattern was likely a consequence of
 the significant changes in competitive dominance between species pairs (26
 changes out of 45; 58%). Although fitness differences were equalised and
 intransitive competition promoted, our model predicted a lower likelihood
 of coexistence under the extreme event for both species pairs and
 triplets, mainly because competitive interactions did not promote enough
 niche differences to balance the observed fitness asymmetries in our
 competitive networks. Synthesis. We empirically proved that an extreme
 climate results in communities with reduced niche and fitness differences
 in which species are less likely to coexist despite the increasing
 prevalence of intransitive competition.

title: Data from: The outcome of competition between two parasitoid species is influenced by a facultative symbiont of their aphid host

description: Symbiotic bacteria can act to protect their host against natural enemies.
 Where this protection is asymmetric against different natural enemies,
 protection conferred by symbionts has the potential to mediate
 interactions between natural enemies, as well as between enemies and the
 host. In pea aphids (Acyrthosiphon pisum), resistance against parasitoid
 wasps can be conferred by facultative symbiotic bacteria. We investigated
 whether the outcome of competition between two parasitoid species can be
 influenced by the presence of a defensive symbiont in the host. We exposed
 pea aphids from a single clonal line, with and without a strain of the
 protective endosymbiont Hamiltonella defensa, to multiparasitism by the
 parasitoid wasps Aphelinus abdominalis (Aphelinidae) and Aphidius ervi
 (Braconidae), and recorded the outcome. The symbiont strain is known to
 impact A. abdominalis more strongly than A. ervi. We found that the
 presence of a strain of the protective endosymbiont H. defensa can reverse
 the outcome of competition between the wasps. In the absence of the
 symbiont, A. ervi gains very little success when attacking an aphid
 previously parasitized by A. abdominalis. However, where the aphids
 possessed the symbiont, A. abdominalis did not develop successfully, and
 the success rate of A. ervi was significantly increased. Our results show
 that defensive facultative symbionts are able to influence community
 interactions at the trophic level above their host.

 laboratory on the effects of symbiont Hamiltonella defensa in pea aphids
 Acyrthosiphon pisum on outcomes of multiparasitism by two parasitoid
 species (Aphidius ervi and Aphelinus abdominalis). Aphids either possessed
 the symbiont Hamiltonella defensa (‘Hamiltonella’ in column ‘Symbiont’) or
 had been cured of their symbiont infection using selective antibiotics
 (‘None’). In Experiment 1, Aphelinus abdominalis attacked first; in
 Experiment 2 Aphidius ervi attacked first. In both experiments, aphids
 were subjected to two parasitism treatments, three days apart (indicated
 by columns labelled ‘First_treatment’ and ‘Second_treatment’). Each
 treatment had three possible options: ‘Aphidius’ (parasitism by Aphidius
 ervi), ‘Aphelinus’ (parasitism by Aphelinus abdominalis) or ‘None’ (aphids
 not exposed to parasitoids). The headings ‘Aphelinus_mummy’,
 ‘Aphidius_mummy’, ‘Live’ and ‘Dead’ refer to the possible outcomes for

title: Data from: Root traits are related to plant water-use among rangeland Mediterranean species

description: 1. Understanding the water-use of plants is timely under increasing
 drought stress due to climate change. Despite the crucial role of roots in
 water uptake, relationships between water-use and root traits are seldom
 considered. 2. Combining a functional traits-based approach with a water
 balance model, we tested whether root functional traits are related to
 spatial and temporal water-use among 12 Mediterranean rangeland species
 grown in common garden monocultures. Soil water content was monitored for
 10 months, and the dynamics of water uptake of each species was modelled
 at a daily time step. Root functional traits were measured at two soil
 depths (shallow and deep soil). 3. Species with fast resource acquisition
 strategies in shallow soil, i.e. thin roots, maximised water uptake in a
 short period and consumed large amounts of water during periods of low
 water availability. Conversely, species with a more conservative root
 strategy, i.e. coarse roots, took up less water during the peak-growing
 season, maintained water uptake over a longer period of time and consumed
 less water during periods of low water availability. Deep root traits are
 strongly related to species’ ability to take up water from deep soil. Deep
 roots with large diameters and low specific root length improve species’
 ability to reach water from deep soil. Biomass investment in the deep soil
 layer was positively related to the amount of water consumed during
 periods of low water availability. 4. Our results highlight that root
 functional traits influence a range of spatial and temporal water-use
 among Mediterranean rangeland species. They account for the amount of
 water taken up during dry periods but not during the entire growing
 season.

title: Data from: Personality, plasticity, and resource defense

description: In many animal taxa, behavior varies both among individuals (animal
 “personalities”) and within individuals (“plasticity”). Personality and
 plasticity may co-vary if individuals differ in responsiveness to changes
 in their environment (“I × E” interaction). The nature and fitness
 implications of individual differences in behavioral plasticity in the
 wild are poorly understood. In territorial animals, fitness depends
 fundamentally on resource-defense behavior—their response to various
 threats from conspecific competitors. Such systems thus offer an ideal
 opportunity to investigate individual differences in behavioral
 plasticity. We used male superb fairy-wrens (Malurus cyaneus) to test for
 individual differences in the intensity and plasticity of territorial
 defense behavior. Using captive assays, we identified behavioral types on
 the basis of fast versus slow exploration of a novel environment (the
 “proactive–reactive” axis of behavior). Then we simulated territorial
 intrusions in the wild, using playback of experimentally manipulated songs
 that differed in trill length in a pair-wise design. Although previous
 work suggests that proactive individuals are more aggressive and less
 responsive than reactive individuals, we found no support for these
 differences in the context of territorial defense in the wild. Fast
 explorers (proactive) and slow explorers (reactive) responded equally
 aggressively to a simulated territorial intrusion overall. Furthermore,
 although fast explorers responded equally strongly to the two different
 playback stimuli, there was little evidence that slow explorers
 differentiated between the two stimuli, and this “I × E” interaction was
 not statistically significant. Further work is needed to determine the
 prevalence in the wild of personality-related differences in behavioral
 plasticity.

title: Data from: Pale by comparison: competitive interactions between signalling female glow-worms

description: When individuals differ in their abilities to compete for a mate, weaker
 competitors may evolve tactics to increase their mating success.
 Exploiting attractiveness of others to get mates is a common tactic in
 many taxa, although examples of this behavior in females are scarce. In
 glow-worms (Lampyris noctiluca L., Coleoptera: Lampyridae), females
 attract males by glowing and males prefer the brightest female. How
 unattractive females succeed in competition for mates is largely
 understudied. We hypothesize that less attractive female glow-worms may
 succeed in competition over mates by parasitizing glow of more attractive
 competitors. We tested our hypothesis with a combination of field and
 laboratory experiments. Contrary to our expectations, we found that
 females move away from brighter competitors. This behavior may explain our
 field observation that females are often more than one meter apart from
 each other. Increasing distance to a brighter female may make comparison
 on brightness difficult for males and increase attractiveness of dimmer
 females. Our study provides evidence of behavior by which less attractive
 competitors may actively avoid competition and therefore affect female
 distribution in nature. This behavior may explain maintenance of variation
 in attractiveness of sexual signals, even in species where mates are
 selected by ornaments. We conclude that sexual competition may play a
 crucial role in spatial distribution. Spatial distribution of competing
 sex affects choosing individuals’ ability to compare mates and thus
 affects mate choice.

title: Data from: Reduced flight-to-light behaviour of moth populations exposed to long-term urban light pollution

description: The globally increasing light pollution is a well-recognized threat to
 ecosystems, with negative effects on human, animal and plant wellbeing.
 The most well-known and widely documented consequence of light pollution
 is the generally fatal attraction of nocturnal insects to artificial light
 sources. However, the evolutionary consequences are unknown. Here we
 report that moth populations from urban areas with high, globally relevant
 levels of light pollution over several decades show a significantly
 reduced flight-to-light behaviour compared with populations of the same
 species from pristine dark-sky habitats. Using a common garden setting, we
 reared moths from 10 different populations from early-instar larvae and
 experimentally compared their flight-to-light behaviour under standardized
 conditions. Moths from urban populations had a significant reduction in
 the flight-to-light behaviour compared with pristine populations. The
 reduced attraction to light sources of ‘city moths' may directly
 increase these individuals' survival and reproduction. We anticipate
 that it comes with a reduced mobility, which negatively affects foraging
 as well as colonization ability. As nocturnal insects are of eminent
 significance as pollinators and the primary food source of many
 vertebrates, an evolutionary change of the flight-to-light behaviour
 thereby potentially cascades across species interaction networks.

title: Data from: Predator olfactory cues generate a foraging-predation tradeoff through prey apprehension

description: Most animals are faced with the challenge of securing food under the risk
 of predation. This frequently generates a trade-off whereby animals
 respond to predator cues with reduced movement to avoid predation at the
 direct cost of reduced foraging success. However, predators may also cause
 prey to be apprehensive in their foraging activities, which would generate
 an indirect ‘apprehension cost’. Apprehension arises when a forager
 redirects attention from foraging tasks to predator detection and incurs a
 cost from such multi-tasking, because the forager ends up making more
 mistakes in its foraging tasks as a result. Here, we test this
 apprehension cost hypothesis and show that damselflies miss a greater
 proportion of their prey during foraging bouts in response to both
 olfactory cues produced by conspecifics that have only viewed a fish
 predator and olfactory cues produced directly by fish. This reduced
 feeding efficiency is in addition to the stereotypical anti-predator
 response of reduced activity, which we also observed. These results show
 that costs associated with anti-predator responses not only arise through
 behavioural alterations that reduce the risk of predation, but also from
 the indirect costs of apprehension and multi-tasking that can reduce
 feeding efficiency under the threat of predation.

title: Data from: Matrix models of hierarchical demography: linking group- and population-level dynamics in cooperative breeders

description: For highly social species, population dynamics depend on hierarchical
 demography that links local processes, group dynamics, and population
 growth. Here, we describe a stage-structured matrix model of hierarchical
 demography, which provides a framework for understanding social influences
 on population change. Our approach accounts for dispersal and affords
 insight into population dynamics at multiple scales. The method has close
 parallels to integral projection models, but focuses on a discrete
 characteristic (group size). Using detailed long-term records for meerkats
 (Suricata suricatta), we apply our model to explore patterns of local
 density dependence and implications of group size for group and population
 growth. Taking into account dispersers, the model predicts a per-capita
 growth rate for social groups that declines with group size. It predicts
 that larger social groups should produce a greater number of new breeding
 groups; thus dominant breeding females (responsible for most reproduction)
 are likely to be more productive in larger groups. Considering the
 potential for future population growth, larger groups have the highest
 reproductive value, but per-capita reproductive value is maximised for
 individuals in smaller groups. Across a plausible range of dispersal
 conditions, meerkats' long-run population growth rate is maximised
 when individuals form groups of intermediate size.
