title: Data from: Dynamic Wolbachia prevalence in Acromyrmex leaf-cutting ants: potential for a nutritional symbiosis

description: Wolbachia are renowned as reproductive parasites, but their phenotypic
 effects in eusocial insects are not well understood. We used a combination
 of qrt-PCR, fluorescence in situ hybridisation, and laser scanning
 confocal microscopy to evaluate the dynamics of Wolbachia infections in
 the leaf-cutting ant Acromyrmex octospinosus across developmental stages
 of sterile workers. We confirm that workers are infected with one or two
 widespread wsp genotypes of Wolbachia, show that colony prevalences are
 always 100%, and characterize two rare recombinant genotypes. One dominant
 genotype is always present and most abundant while another only
 proliferates in adult workers of some colonies and is barely detectable in
 larvae and pupae. An explanation may be that Wolbachia genotypes compete
 for host resources in immature stages while adult tissues provide
 substantially more niche space. Tissue-specific prevalences of the two
 genotypes differ, with the rarer genotype being overrepresented in the
 adult foregut and thorax muscles. Both genotypes occur extra-cellularly in
 the foregut, suggesting an unknown mutualistic function in worker ant
 nutrition. Both genotypes are also abundant in the faecal fluid of the
 ants, suggesting that they may have extended functional phenotypes in the
 fungus garden that the ants manure with their own faeces.

title: Data from: The interactive effects of competition and predation risk on dispersal in an insect.

description: Dispersal dynamics have significant consequences for ecological and
 evolutionary processes. Previous work has demonstrated that dispersal can
 be context-dependent. However, factors affecting dispersal are typically
 considered in isolation, despite the probability that individuals make
 dispersal decisions in response to multiple, possibly interacting factors.
 We examined whether two ecological factors, predation risk and
 intraspecific competition, have interactive effects on dispersal dynamics.
 We performed a factorial experiment in mesocosms using backswimmers
 (Notonecta undulata), flight-capable, semi-aquatic insects. Emigration
 rates increased with density, and increased with predation risk at
 intermediate densities; however, predation had minimal effects on
 emigration at high and low densities. Our results indicate that factorial
 experiments may be required to understand dispersal dynamics under
 realistic ecological conditions.

title: Data from: Covariance of paternity and sex with laying order explains male bias in extra-pair offspring in a wild bird population

description: It has been hypothesized that parents increase their fitness by biasing
 the sex ratio of extra-pair offspring (EPO) towards males. Here, we report
 a male bias among EPO in a wild population of blue tits (Cyanistes
 caeruleus). This resulted from a decline in both the proportion of males
 and EPO over the laying order of eggs in the clutch. However, previous
 studies suggest that, unlike the decline in EPO with laying order, the
 relationship between offspring sex ratio and laying order is not
 consistent between years and populations in this species. Hence, we
 caution against treating the decline in proportion of males with laying
 order, and the resulting male bias among EPO, as support for the above
 hypothesis. Variable patterns of offspring sex and paternity over the
 laying order may explain inconsistent associations between offspring sex
 and paternity, between and within species.

title: Data from: Multiple-stressor effects on leaf litter decomposition and fungal decomposers in agricultural streams contrast between litter species

description: Agricultural land use commonly exerts multiple stressors on the
 functioning of stream ecosystems, including leaf litter decomposition and
 the utilization of this resource in stream food webs. If stressors
 interact, their cumulative effects on biotic responses cannot be predicted
 from knowledge of individual stressor effects, posing challenges for
 management and restoration of these ecosystems. We examined the individual
 and interactive effects of four common agricultural stressors and the role
 of litter quality on leaf litter decomposition and fungal decomposers. In
 128 outdoor, flow-through mesocosms, we manipulated levels of nutrients, a
 nitrification inhibitor (dicyandiamide), deposited fine sediment, and flow
 velocity. Interactions among these stressors can ensue because, for
 instance, they jointly affect physicochemical conditions around leaf
 litter such as the availability of dissolved oxygen and nutrients. The two
 litter species used, deciduous birch and evergreen mahoe, showed
 contrasting decomposition dynamics and these differences influenced their
 response to stressors. Fungi were important for birch litter decomposition
 but played a minor role for mahoe. Overall, flow velocity reduction and
 deposited fine sediment had the strongest, mainly negative effects on
 fungi and litter decomposition, probably as a consequence of reductions in
 dissolved oxygen available to fungi. However, fine sediment substantially
 increased mahoe litter mass loss, pointing at fungi-independent processes
 being relevant for its decomposition. Although interactions among
 stressors were uncommon, they showed effects of the same magnitude as
 stressor main effects. Potential mechanisms underlying interactions
 included reductions in dissolved oxygen and changes in microbial community
 composition. Knowledge of the effects of multiple agricultural stressors
 and of litter quality on litter decomposition and litter-associated fungi
 is crucial for management of forested riparian corridors, which have been
 shown to efficiently mitigate impacts of agricultural stressors on
 streams. The contrasting responses of the litter species used in our study
 warrant consideration of species diversity of the riparian vegetation.

title: Data from: Can physiological engineering/programming increase multi-generational thermal tolerance to extreme temperature events?

description: Organisms increasingly encounter higher frequencies of extreme weather
 events as a consequence of global climate change. Currently, few
 strategies are available to mitigate climate change effects on animals
 arising from acute extreme high temperature events. We tested the capacity
 of physiological engineering to influence the intra- and
 multi-generational upper thermal tolerance capacity of a model organism
 Artemia, subjected to extreme high temperatures. Enhancement of specific
 physiological regulators during development could affect thermal
 tolerances or life-history attributes affecting subsequent fitness. Using
 experimental Artemia populations we exposed F0 individuals to one of four
 treatments; heat hardening (28 &[deg]C to 36 &[deg]C, 1
 &[deg]C per 10 minutes), heat hardening plus serotonin (0.056 μg
 ml-1), heat hardening plus methionine (0.79 mg ml-1), and a control
 treatment. Regulator concentrations were based on previous literature.
 Serotonin may promote thermotolerance, acting upon metabolism and
 life-history. Methionine acts as a methylation agent across generations.
 For all groups, measurements were collected for three performance traits
 of individual thermal tolerance (upper sublethal thermal limit, lethal
 limit, and dysregulation range) over two generations. Results showed no
 treatment increased upper thermal limit during acute thermal stress,
 although serotonin-treated and methionine-treated individuals outperformed
 controls across multiple thermal performance traits. Additionally, some
 effects were evident across generations. Together these results suggest
 phenotypic engineering provides complex outcomes; and if implemented with
 heat hardening can further influence performance in multiple thermal
 tolerance traits, within and across generations. Potentially, such
 techniques could be up-scaled to provide resilience and stability in
 populations susceptible to extreme temperature events.

title: Data from: Food restriction and chronic stress alter energy use and affect immunity in an infrequent feeder

description: Glucocorticoids are important mediators of energy utilization for key
 physiological processes, including immune function. Much work has focused
 on the effects of energy limitation and stress for key physiological
 processes such as reproduction and immunity. However, it is unclear how
 stress alters energy use across different energy states, and the
 physiological ramifications of such effects are even less clear. In this
 study, we altered energy and stress states of an infrequent feeder, the
 Terrestrial Gartersnake (Thamnophis elegans), using fasting and repeated
 restraint stress (Chronic Stressors) to test how these challenges
 interacted to affect immune function, energy metabolites, and
 glucocorticoid reactivity (a traditional indicator of stress state) to
 restraint stress, a standardized, acute stressor. After this acute
 stressor, the snakes which had received chronic stress had increased
 glucocorticoid reactivity, and both treatments altered energy metabolite
 use and storage. Evidence of interaction of food restriction and chronic
 stress treatments on innate immune function and energy metabolites
 (triglycerides and glycerol) suggests that stress alters energy use in a
 manner dependent on the energy state of the animal. Snakes have a
 remarkable ability to maintain functionality of key physiological
 processes under stressful conditions but are still susceptible to multiple
 simultaneous stressors, a situation increasingly prevalent in our
 ever-changing environment.

title: Data from: Metapopulation dynamics of species with cryptic life stages

description: Quantifying metapopulation dynamics is a challenging task. Difficulties
 particularly arise in species that possess unobservable resistance forms
 that bias the estimation of colonization and persistence rates. Here, we
 develop a general multistate occupancy model that allows estimation of
 species persistence for both normal and resistant forms, even when the
 latter are not detectable. We apply this model to an 11-year data set on
 the tropical freshwater snail Drepanotrema depressissimum in a network of
 229 ponds. These ponds frequently dry out, and the snails can persist by
 aestivating in the ground, where they are not detected. Our model
 adequately captures this feature because it infers a high persistence rate
 for the resistant form, while models ignoring aestivation tend to
 overestimate extinction and colonization. In addition, we find that,
 surprisingly, colonization and persistence are even higher in sites prone
 to desiccation and during years with low rainfall than in more humid sites
 and years, suggesting that D. depressissimum favors unstable sites where
 competitors are rare and where it can rely on aestivation to persist. Our
 model has the potential to provide valuable insights into the
 metapopulation dynamics of many species that otherwise could hardly be
 studied because of the existence of undetectable life forms.

title: Data from: Assessing for interaction between APOE ε4, sex, and lifestyle on cognitive abilities

description: Objective: To test for statistically significant interactions between
 apolipoprotein (APOE) e4 genotype, and lifestyle factors on worse
 cognitive abilities in UK Biobank. Methods: Using UK Biobank cohort data,
 we tested for statistically significant interactions between APOE e4
 allele presence, lifestyle factors of alcohol intake, smoking, total
 physical activity and obesity, and sex, on cognitive tests of reasoning,
 information processing speed and executive function (n
 range=70,988-324,725 depending on the test). We statistically adjusted for
 potential confounders of age, sex, deprivation, cardiometabolic
 conditions, and educational attainment. Results: There were significant
 associations between APOE e4 and worse cognitive abilities, independent of
 potential confounders, and between lifestyle risk factors and worse
 cognitive abilities, however there were no statistically significant
 interactions at multiple correction-adjusted P&lt;0.05, against our
 hypotheses. Conclusions: Our results do not provide support for the idea
 that e4 genotype increases vulnerability to the negative effects of
 lifestyle risk factors on cognitive ability, but rather support a
 primarily outright association between APOE e4 genotype and worse
 cognitive ability.

title: Data from: Nematode parasite diversity in birds: the role of host ecology, life history and migration

description: Previous studies have found that migratory birds generally have a more
 diverse array of pathogens such as parasites, as well as higher
 intensities of infection. However, it is not clear whether this is driven
 by the metabolic and physiological demands of migration, differential
 selection on host life-history traits or basic ecological differences
 between migratory and non-migratory species. Parasitic helminths can cause
 significant pathology in their hosts, and many are trophically transmitted
 such that host diet and habitat use play key roles in the acquisition of
 infections. Given the concurrent changes in avian habitats and migratory
 behaviour, it is critical to understand the degree to which host ecology
 influences their parasite communities. We examined nematode parasite
 diversity in 153 species of Anseriformes (water birds) and Accipitriformes
 (predatory birds) in relation to their migratory behaviour, diet, habitat
 use, geographic distribution and life history using previously published
 data. Overall, migrators, host species with wide geographic distributions
 and those utilizing multiple aquatic habitats had greater nematode
 richness (number of species), and birds with large clutches harboured more
 diverse nematode fauna with respect to number of superfamilies. Separate
 analyses for each host order found similar results related to
 distribution, habitat use and migration; however, herbivorous water birds
 played host to a less diverse nematode community compared to those that
 consume some animals. Birds using multiple aquatic habitats have a more
 diverse nematode fauna relative to primarily terrestrial species, likely
 because there is greater opportunity for contact with parasite infectious
 stages and/or consumption of infected hosts. As such, omnivorous and
 carnivorous birds using aquatic habitats may be more affected by
 environmental changes that alter their diet and range. Even though there
 were no overall differences in their ecology and life history compared
 with non-migrators, migratory bird species still harboured a more diverse
 array of nematodes, suggesting that this behaviour places unique demands
 on these hosts and warrants further study.
