title: Data from: Caste ratio adjustments in response to perceived and realised competition in parasites with division of labour

description: 1. Colonial organisms with division of labour are assumed to achieve
 increased colony-level efficiency in task performance through functional
 specialisation of individuals into distinct castes. In social insects,
 ratios of individuals in different castes can adjust adaptively in
 response to external threats. However, whether flexibility in caste ratio
 also occurs in other social organisms with division of labour remains
 unclear. Some parasitic trematodes, in which clonal colonies within the
 snail intermediate host comprise a reproductive caste and a soldier caste,
 offer good systems to test the general nature of adaptive caste ratio
 adjustments. 2. Using the trematode Philophthalmus sp. as model, we test
 whether trematode colonies shift their composition toward more soldiers
 when exposed to a sustained risk of invasion by a competitor parasite
 species, and/or when experiencing sustained, active competition. We also
 quantify the colony-level fitness impact of caste ratio adjustments,
 measured as the colony’s output of larval infective stages. 3. We
 conducted two long-term laboratory experiments on within-snail trematode
 colonies. First, snails harbouring Philophthalmus colonies were exposed to
 different levels of invasion risk by another trematode species, Maritrema
 novaezealandense. Second, the structure of Philophthalmus colonies was
 quantified after a year-long period of within-snail competition with the
 other trematode species. 4. When facing the risk of invasion by a
 competitor, independently of the level of risk, Philophthalmus colonies
 showed a significant shift toward producing more soldiers, resulting in
 altered caste ratio. Similarly, when experiencing actual competition by
 another trematode established in the same snail, Philophthalmus colonies
 also adjusted by producing significantly more soldiers. Greater
 investments in defense via more soldiers had negative impacts on the
 establishment and size of the competitor’s colonies. Nevertheless, the
 presence of the competitor reduced the fitness (output of infective
 stages) of Philophthalmus colonies, although the production of more
 soldiers mitigated that effect. 5. Our findings demonstrate that trematode
 colonies with division of labour are capable of adaptive caste ratio
 adjustments in response to both the perceived threat of competition, and
 actual competition, with trade-offs against reproductive success only
 apparent when soldier numbers are very high. Combined with results on
 social insects, our study suggests parallel adaptations of colonial
 organisms in phylogenetically disparate organisms.

title: Data from: Mountain pine beetle host-range expansion threatens the boreal forest

description: The current epidemic of the mountain pine beetle (MPB), an indigenous pest
 of western North American pine, has resulted in significant losses of
 lodgepole pine. The leading edge has reached Alberta where forest
 composition shifts from lodgepole to jack pine through a hybrid zone. The
 susceptibility of jack pine to MPB is a major concern, but there has been
 no evidence of host-range expansion, in part due to the difficulty in
 distinguishing the parentals and their hybrids. We tested the utility of a
 panel of microsatellite loci optimized for both species to classify
 lodgepole pine, jack pine and their hybrids using simulated data. We were
 able to accurately classify simulated individuals, and hence applied these
 markers to identify the ancestry of attacked trees. Here we show for the
 first time successful MPB attack in natural jack pine stands at the
 leading edge of the epidemic. This once unsuitable habitat is now a novel
 environment for MPB to exploit, a potential risk which could be
 exacerbated by further climate change. The consequences of host-range
 expansion for the vast boreal ecosystem could be significant.
description: HostExpansion_dryadentryMicrosatellite profiles for lodgepole pine and jack pine collected in BC, AB, SK, ON and MN used to develop a method of reliably identifying pure species and their hybrids. These data were used to document the host-range expansion of mountain pine beetle into jack pine. Included with the 11 microsatellie profiles are the location names (corresponding to the manuscript) and the geographic coordinates (lat/long).

title: Data from: Forest fire severity affects host plant quality and insect herbivore damage

description: Climate change models predict increased forest fire occurrence and
 severity in the near future. Forest fire disturbance affects multiple
 ecological interactions, but there is little evidence for how
 naturally-occurring fires affect plant quality and herbivore damage, which
 is important because plants and herbivorous insects comprisemost of the
 diversity in natural ecosystems and are responsible for a variety of
 ecosystem services. We surveyed three fires in the Rocky Mountains to
 investigate the effects of fire severity on wax currant (Ribes cereum), an
 important source of food and cover for wildlife in Colorado. We measured
 plant quality and herbivore damage; we found that fire severity had a
 significant negative effect on both measures. Notably, high severity fires
 decreased herbivore damage by about 50%. Furthermore, we found that the
 effect of fire on insect herbivore damage is mostly direct, but that
 indirect effects mediated through changes in plant quality are also
 significant. Our results have important implications for the effects of
 climate-driven increases in fire severity on plant-insect interactions,
 illustrating strong direct and weaker indirect negative effects of fire
 severity in a forest ecosystem.

title: Data from: Phylogeny and evolution of endemic species on Ulleungdo Island, Korea: the case of Fagus multinervis (Fagaceae)

description: The genus Fagus (beech, Fagaceae) consists of about 10 species
 discontinuously distributed in East Asia, eastern North America, and
 Europe. Fagus multinervis occurs only on Ulleungdo Island, Korea, and is
 an important component of the island's plant community. The species
 was described primarily based on one of its stem characteristics: it
 branches at the base, producing several primary trunks. In part because no
 extant Fagus species are found in mainland Korea, and because the closest
 populations of Fagus are found in Japan, F. multinervis has been
 considered to be derived from the Japanese species, F. japonica. However,
 a recent study synonymized F. multinervis under F. engleriana and proposed
 that the beech population of Ulleungdo Island was derived instead from
 China via long-distance dispersal. Fagus multinervis is morphologically
 very similar to F. engleriana, but it can be distinguished by having
 rhombic lenticels that are vertically elongated. We determined the
 nucleotide sequences of the trnK-matK, trnL-trnF, trnH-psbA, and atpB-rbcL
 regions of plastid DNA and the second intron of the nuclear LEAFY gene
 from accessions of eight species, including eight F. multinervis
 individuals, in order to clarify the phylogenetic placement of this
 insular species. Phylogenetic analyses show that F. multinervis is
 monophyletic, and that it is closely related to F. engleriana and F.
 japonica. However, a sister relationship of F. multinervis with either of
 those species is not resolved. Therefore, our molecular data support the
 distinctness of F. multinervis as an endemic on Ulleungdo Island.
 Furthermore, incongruence between plastid and nuclear data suggests that
 F. multinervis may have originated via hybridization.

title: Data from: MnO2–graphene nanosheets wrapped mesoporous carbon/sulfur composite for lithium–sulfur batteries

description: The lithium-sulfur battery has received intense interest due to its
 achievable high energy density and low cost sulfur. However, fast capacity
 retention after a prolonged cycles is the main challenge. Here, we report
 to synthesis MnO2-graphene nanosheets coated mesoporous carbon/sulfur
 composite (MGN@MC/S) as cathodes in the Li-S battery. The MGN@MC/S
 electrode exhibits excellent electrochemical performance, with high
 reversible specific capacity and rate capability (1475 mA h g-1 at 0.1 C
 and 748 mA h g-1 at 1 C ), and long-cycle ability (0.042 % capacity decay
 per cycle over more than 450 cycles at 1 C).

title: Data from: The perceptual shaping of anticipatory actions

description: Humans display anticipatory motor responses to minimize the adverse
 effects of predictable perturbations. A widely accepted explanation for
 this behavior relies on the notion of an inverse model that, learning from
 motor errors, anticipates corrective responses. Here, we propose and
 validate the alternative hypothesis that anticipatory control can be
 realized through a cascade of purely sensory predictions that drive the
 motor system, reflecting the causal sequence of the perceptual events
 preceding the error. We compare both hypotheses in a simulated
 anticipatory postural adjustment task. We observe that adaptation in the
 sensory domain, but not in the motor one, supports the robust and
 generalizable anticipatory control characteristic of biological systems.
 Our proposal unites the neurobiology of the cerebellum with the theory of
 active inference and provides a concrete implementation of its core tenets
 with great relevance both to our understanding of biological control
 systems and, possibly, to their emulation in complex artefacts.

title: Data from: Stress hormones mediate predator-induced phenotypic plasticity in amphibian tadpoles

description: Amphibian tadpoles display extensive anti-predator phenotypic plasticity,
 reducing locomotory activity and, with chronic predator exposure,
 developing relatively smaller trunks and larger tails. In many
 vertebrates, predator exposure alters activity of the neuroendocrine
 stress axis. We investigated predator-induced effects on stress hormone
 production and the mechanistic link to anti-predator defences in Rana
 sylvatica tadpoles. Whole-body corticosterone (CORT) content was
 positively correlated with predator biomass in natural ponds. Exposure to
 caged predators in mesocosms caused a reduction in CORT by 4 hours, but
 increased CORT after 4 days. Tadpoles chronically exposed to exogenous
 CORT developed larger tails relative to their trunks, matching
 morphological changes induced by predator chemical cue; this predator
 effect was blocked by the corticosteroid biosynthesis inhibitor
 metyrapone. Tadpole tail explants treated in vitro with CORT increased
 tissue weight, suggesting that CORT acts directly on the tail. Short-term
 treatment of tadpoles with CORT increased predation mortality, likely due
 to increased locomotory activity. However, long-term CORT treatment
 enhanced survivorship, likely due to induced morphology. Our findings
 support the hypothesis that tadpole physiological and
 behavioural/morphological responses to predation are causally
 interrelated. Tadpoles initially suppress CORT and behaviour to avoid
 capture, but increase CORT with longer exposure, inducing adaptive
 phenotypic changes.

title: Data from: Temperature- and latitude-specific individual growth rates shape the vulnerability of damselfly larvae to a widespread pesticide

description: 1. Freshwater ecosystems are especially vulnerable to climate change and
 pollution. One key challenge for aquatic toxicology is to determine and
 manage the combined effects of temperature increase and contaminants
 across species' ranges. 2. We tested how thermal adaptation and
 life-history evolution along a natural temperature gradient influence the
 vulnerability of an aquatic insect to a pesticide under global warming. We
 applied a space-for-time substitution approach to study the effect of
 warming on the vulnerability of Ischnura elegans damselfly larvae to the
 pesticide chlorpyrifos in a common garden warming experiment (20 and 24
 °C) with replicated populations from three latitudes spanning &gt;1500
 km in Europe. 3. Chlorpyrifos was more toxic to damselfly larvae at the
 higher temperature: mortality only occurred at 24 °C and the reductions in
 growth rate were stronger at 24 °C. This could partly be explained by
 parallel reductions in food intake but not by the activities of two
 widespread enzymatic biomarkers, glutathione S-transferase (GST) and
 acetylcholinesterase (AChE). 4. There was some evidence that the increased
 toxicity of the high chlorpyrifos concentration at 24 °C was stronger in
 terms of growth reduction in the faster-growing larvae from the
 low-latitude populations. This is consistent with energy allocation
 trade-offs between growth rate and pesticide tolerance, but suggests that
 local thermal adaptation does not play a role in coping with pesticide
 stress. 5. Synthesis and applications. Damselfly larvae from populations
 in lower latitudes were more vulnerable to a common pesticide at higher
 temperatures and pesticide concentrations, whereas evidence for the
 influence of local thermal adaptation on the vulnerability of larvae was
 weak. These results emphasize the need for spatially explicit
 bioassessment and conservation tools. Management practices aimed at
 mitigating pesticide run-off into aquatic ecosystems are particularly
 important in agricultural areas at low latitudes.

title: Data from: Comparative phylogeography reveals a shared impact of Pleistocene environmental change in shaping genetic diversity within nine Anopheles mosquito species across the Indo-Burma biodiversity hotspot

description: Southeast Asia is one of the world’s richest regions in terms of
 biodiversity. An understanding of the distribution of diversity and the
 factors shaping it is lacking, yet essential for identifying conservation
 priorities for the region’s highly threatened biodiversity. Here we take a
 large scale comparative approach, combining data from nine forest
 associated Anopheles mosquito species and using statistical
 phylogeographic methods to disentangle the effects of environmental
 history, species specific ecology, and random coalescent effects.
 Spatially explicit modelling of Pleistocene demographic history supports a
 common influence of environmental events in shaping the genetic diversity
 of all species examined, despite differences in species' mtDNA gene
 trees. Populations were periodically restricted to allopatric northeastern
 and northwestern refugia, most likely due to Pleistocene forest
 fragmentation. Subsequent southwards post-glacial recolonisation is
 supported by a north-south gradient of decreasing genetic diversity.
 Repeated allopatric fragmentation and recolonisation has led to the
 formation of deeply divergent geographical lineages within four species
 and a suture zone where these intraspecific lineages meet along the
 Thai-Myanmar border. A common environmental influence for this divergence
 was further indicated by strong support for simultaneous divergence within
 the same four species, dating to approximately 900 kya. Differences in the
 geographical structuring of genetic diversity between species are likely
 the result of varying species’ biology. The findings have important
 implications for conservation planning; if the refugial regions and suture
 zone identified here are shared by other forest taxa, the unique and high
 levels of genetic diversity they house will make these areas conservation
 priorities.

title: Data from: Using survival models to estimate invertebrate prey identification times in a generalist stream fish

description: Estimates of predator feeding rates are important for understanding
 trophic dynamics. One common method for quantifying feeding rates in
 fishes combine mass-based diet data with gastric evacuation times to
 estimate prey mass consumed per predator. An alternative approach is to
 estimate rates of prey individuals consumed using prey identification
 times − the time period over which prey remain identifiable in a
 predator’s stomach. One challenge with the analysis of prey identification
 times, however, is that the response variable is likely to be censored
 because the ‘true’ prey identification time cannot be observed directly.
 Here, we applied survival analysis that can incorporate censored data to
 estimate the effects of predator body size, water temperature, and prey
 characteristics (type, count and body size) on identification times in
 reticulate sculpin (Cottus perplexus). We focused on seven types of prey
 that are common in this generalist predator’s diet: mayflies
 (Ephemeroptera), caddisflies (Trichoptera), stoneflies (Plecoptera), flies
 (Diptera), beetles (Coleoptera), worms (Annelida), and sculpin eggs. An
 information-theoretic model comparison approach indicated that an
 accelerated failure-time Weibull model with all five covariates provided
 the best relative fit to the full dataset. Prey type had a strong effect
 on prey identification times, with annelid worms having the shortest times
 (&lt; 1 hr) and caddisflies having the longest times (&gt; 15
 hrs). Water temperature decreased prey identification times (7.5% per 1°C
 increase), whereas prey count (i.e. meal size) increased prey
 identification times (15.5% per additional prey item). Sculpin body size
 had a weak negative effect on prey identification times (0.04% per 1 mm
 increase). Body sizes of some taxa, including mayflies, caddisflies, and
 stoneflies, increased prey identification times, leading to an interaction
 between prey type and prey size. Our study highlights the utility of
 survival analysis to quantify variation in prey identification times in
 the diets of generalist predators.

title: Data from: Cascading spatial and trophic impacts of oak decline on the soil food web

description: 1. Tree defoliation and mortality have considerably increased worldwide
 during the last decades due to global change drivers such as increasing
 drought or invasive pests and pathogens. However, the effects of this tree
 decline on soil food webs are poorly understood. 2. In this study we
 evaluated the impacts of Quercus suber decline on soil food webs of
 Mediterranean mixed forests invaded by the exotic oomycete pathogen
 Phytophthora cinnamomi, using soil nematodes as bioindicator taxa. We used
 a spatially-explicit neighborhood approach to predict the characteristics
 of the nematode community (diversity, trophic structure, and several
 indices indicative of soil food web conditions) as a function of the
 characteristics of the tree and shrub community (species composition, size
 and health status). 3. Our results indicate that the process of
 defoliation and mortality of Q. suber caused significant alterations in
 the nematode trophic structure increasing the abundance of lower trophic
 levels (bacterivores, fungivores and herbivores) and decreasing the
 abundance of higher levels (predators and omnivores). Furthermore, Q.
 suber decline altered the functional composition of soil communities,
 producing a setback of the ecological succession in the soil food web to
 an earlier stage (decrease in the maturity index and increase in the
 plant-parasitic index), simplified soil food webs (decrease in the
 structure index), and shifts in the predominant decomposition channel
 (increase in the fungivores/bacterivores ratio). 4. We also detected
 contrasting characteristics of the nematode community in neighborhoods
 dominated by coexistent woody species, which suggests potential for
 long-term indirect effects on soil food webs due to the substitution of Q.
 suber by non-declining species. 5. Synthesis: Our study provides novel
 results that show the major impacts that ongoing health deterioration of
 dominant tree species can have on the structure and composition of soil
 food webs in forest systems invaded by exotic pathogens, with cascading
 consequences for soil biogeochemical processes in both the short- and
 long-term.
