title: Data from: Aposematism in the burying beetle? Dual function of anal fluid in parental care and chemical defense

description: Burying beetles (Nicrophorus vespilloides) bear distinctive and variable
 orange-black patterning on their elytra and produce an anal exudate from
 their abdomen when threatened. During breeding, the anal exudates
 contribute to the antimicrobial defense of the breeding resource. We
 investigated whether the anal exudates also provide a responsive chemical
 defense, which is advertised to potential avian predators by the beetle’s
 orange and black elytral markings. We found that that the orange-black
 elytral markings of the burying beetle are highly conspicuous for avian
 predators against range of backgrounds, by using computer simulations.
 Using bioassays with wood ants, we also showed that the burying beetle’s
 anal exudates are aversive to potential predators. From these results, and
 other evidence in the literature, we conclude that the evidence for
 aposematism in the burying beetle is as strong as the evidence for many
 other classically aposematic species, such as defended Hymenopterans,
 ladybirds, or poisonous frogs. Nevertheless, we also report unexpectedly
 high levels of individual variation in coloration and chemical defenses,
 as well as sex differences. We suggest that this variation might be partly
 due to conflicting selection pressures, particularly on the dual function
 of the exudates, and partly to nutritional differences in the
 developmental environment. The ecology of the burying beetles (Nicrophorus
 spp.) differs markedly from better-studied aposematic insects. This genus
 thus offers new potential for understanding the evolution of aposematism
 in general.

title: Data from: Succinate links atrial dysfunction and cardioembolic stroke

description: Objective: To determine whether altered metabolic profiles represent a
 link between atrial dysfunction and cardioembolic (CE) stroke, and thus
 whether underlying dysfunctional atrial substrate may contribute to
 thromboembolism risk in CE stroke. Methods: One hundred forty-four
 metabolites were measured using liquid chromatography-tandem mass
 spectrometry in plasma samples collected within 9 hours of stroke onset in
 367 acute stroke patients. Stroke subtype was assigned using the causative
 classification of stroke, and CE stroke (n=181) was compared to non-CE
 stroke (n=186). Markers of left atrial dysfunction included abnormal
 atrial function (P-wave terminal force in lead V1, PTFV1 &gt;4000
 µV•ms), left atrial enlargement on echocardiography, and frank atrial
 fibrillation on electrocardiograms. Stroke recurrence risk was assessed
 using CHADS2 and CHA2DS2-VASc scores. Associations between metabolites and
 CE stroke, atrial dysfunction, and stroke recurrence risk were evaluated
 using logistic regression models. Results: Three tricarboxylic acid (TCA)
 cycle acids, succinate (OR 1.71, 95% CI 1.36-2.15, P=1.37x10-6),
 alpha-ketoglutarate (OR 1.62, 95% CI 1.29-2.04, P=1.62x10-5), and malate
 (OR 1.58, 95% CI 1.26-1.97, P=2.57x10-5), were associated with CE stroke.
 Succinate (OR 1.36, 95% CI 1.31-1.98, P=1.22x10-6), alpha-ketoglutarate
 (OR 2.14, 95% CI 1.60-2.87, P=2.08x10-8), and malate (OR 2.02, 95% CI
 1.53-2.66, P=1.60x10-7) were among metabolites also associated with
 subclinical atrial dysfunction. Of these, succinate was also associated
 with left atrial enlargement (OR 1.54, 95% CI 1.23-1.94, P=1.06x10-4) and
 stroke recurrence based on dichotomized CHADS2 (OR 2.63, 95% CI 1.68-4.13,
 P=3.00x10-6) and CHA2DS2-VASc (OR 2.43, 95% CI 1.60-3.68, P=4.25x10-6)
 scores. Conclusions: Metabolite profiling identified changes in succinate
 associated with CE stroke, atrial dysfunction, and stroke recurrence,
 revealing a putative underlying link between CE stroke and energy
 metabolism.

title: Data from: Trophic interactions in an ant nest microcosm: a combined experimental and stable isotope (δ13C/δ15N) approach

description: Living in close association with other organisms has proven to be a
 widespread and successful strategy in nature. Some communities are
 completely driven by symbiotic associations and therefore, intimate
 relationships among the partners can be expected. Here, we analyzed
 in-depth the food web of a particularly rich community of arthropods found
 in strict association with European red wood ants (Formica rufa group). We
 studied the trophic links between different ant-associated myrmecophiles
 and food sources associated with the host ant, but also tested
 predator–prey links among myrmecophiles themselves. Our approach combined
 direct feeding tests and stable carbon and nitrogen isotope analyses for a
 large number of myrmecophiles. The results of the direct feeding tests
 reveal a complex food web. Most myrmecophiles were found to parasitize on
 ant brood. Moreover, we encountered multiple trophic predator– prey links
 among the myrmecophiles. The results of the stable isotope analyses
 complement these findings and indicate the existence of multiple trophic
 levels and trophic isotopic niche compartmentalization. δ15N values were
 strongly correlated with the trophic levels based on the direct tests,
 reflecting that δ15N values of myrmecophiles increased with higher trophic
 levels. This strong correlation underlines the strength of stable isotopes
 as a powerful tool to assess trophic levels. In addition, the stable
 isotope data suggest that most species only facultatively prey on ant
 brood. The presence of numerous trophic interactions among symbionts
 clearly contrasts with the traditional view of social insects nests as
 offering an enemy-free space for symbionts. Interestingly, the ant host
 can indirectly benefit from these interactions because brood predators are
 also preyed upon by other myrmecophiles. Overall, this study provides
 unique insights into the complex interactions in a small symbiont
 microcosm system and suggests that the interactions between host and
 symbiont might be mediated by other symbionts in the same community.

title: Data from: Episodic disturbance from boat anchoring is a major contributor to, but does not alter the trajectory of, long-term coral reef decline

description: Isolating the relative effects of episodic disturbances and chronic
 stressors on long-term community change is challenging. We assessed the
 impact of an episodic disturbance associated with human visitation (boat
 anchoring) relative to other drivers of long-term change on coral reefs. A
 one-time anchoring event at Crab Cove, British Virgin Islands, in 2004
 caused rapid losses of coral and reef structural complexity that were
 equal to the cumulative decline over 23 years observed at an adjacent
 site. The abundance of small site-attached reef fishes dropped by
 approximately one quarter after the anchoring event, but this drop was not
 immediate and only fully apparent two years after the anchoring event.
 There was no obvious recovery from the impact, and no evidence that this
 episodic impact accelerated or retarded subsequent declines from other
 causes. This apparent lack of synergism between the effect of this
 episodic human impact and other chronic stressors is consistent with the
 few other long-term studies of episodic impacts, and suggests that action
 to mitigate anchor damage should yield predictable benefits.

title: Data from: Specialized avian Haemosporida trade reduced host breadth for increased prevalence

description: Parasite specialization on one or a few host species leads to a reduction
 in the total number of available host individuals, which may decrease
 transmission. However, specialists are thought to be able to compensate by
 increased prevalence in the host population and increased success in each
 individual host. Here, we use variation in host breadth among a community
 of avian Haemosporida to investigate consequences of generalist and
 specialist strategies on prevalence across hosts. We show that specialist
 parasites are more prevalent than generalist parasites in host populations
 that are shared between them. Moreover, the total number of infections of
 generalist and specialist parasites within the study area did not vary
 significantly with host breadth. This suggests that specialists can infect
 a similar number of host individuals as generalists, thus compensating for
 a reduction in host availability by achieving higher prevalence in a
 single host species. Specialist parasites also tended to infect older
 hosts, whereas infections by generalists were biased towards younger
 hosts. We suggest that this reflects different abilities of generalists
 and specialists to persist in hosts following infection. Higher abundance
 and increased persistence in hosts suggest that specialists are more
 effective parasites than generalists, supporting the existence of a
 trade-off between host breadth and average host use among these parasites.

title: Data from: Experimental insight into the process of parasite community assembly

description: 1.Community assembly is a fundamental process that has long been a central
 focus in ecology. Extending community assembly theory to communities of
 co-infecting parasites, we used a gastrointestinal nematode removal
 experiment in free-ranging African buffalo to examine community assembly
 patterns and processes. 2.We first asked whether reassembled communities
 differ from undisturbed communities by comparing anthelmintic-treated and
 control hosts. Next, we examined the temporal dynamics of assembly using a
 cross-section of communities that reassembled for different periods of
 time since last experimental removal. Next, we tested for evidence of
 assembly processes that might drive such reassembly patterns:
 environmental filtering based on host traits (i.e. habitat patches),
 interspecific interactions, priority effects, and chance dispersal from
 the environmental pool of infective stages (i.e. the regional species
 pool). 3.On average, reassembled parasite communities had lower
 abundances, but were more diverse and even, and these patterns varied
 tightly with reassembly time. Over time, the communities within treated
 hosts progressively resembled controls as diversity and evenness decreased
 while total abundance increased. Notably, experimental removal allowed us
 to attribute observed differences in abundance, diversity, and evenness to
 the process of community assembly. 4.During early reassembly, parasite
 accumulation was biased towards a subordinate species and, by excluding
 stochastic assembly processes (i.e. chance dispersal and priority
 effects), we were able determine that early assembly is deterministic.
 Later in the reassembly process, we established that host traits, as well
 as stochastic dispersal from the environmental pool infective stages, can
 affect community composition. 5.Overall, our results suggest there is a
 high degree of resiliency and environmental dependence to the worm
 communities of buffalo. More generally, our data show that both
 deterministic and stochastic processes may play a role in the assembly of
 parasite communities of wild hosts, but their relative importance may vary
 temporally. Consequently, the best strategy for managing reassembling
 parasite communities may also need to shift over time.

title: Data from: Understanding the stoichiometric limitation of herbivore growth: the importance of feeding and assimilation flexibilities

description: Ecological stoichiometry suggests that herbivore growth is limited by
 phosphorus when this element in the diet is &lt; 8.6 µgP mg C-1 (C:P
 atomic ratio &gt;300). However, in nature, it is not necessarily
 related to the relative phosphorus content in diets. This may be the
 result of complex feeding and assimilation responses to diets. We examined
 these possibilities using herbivorous plankton fed mono-specific and mixed
 algae varying in phosphorus content of 1.6 to 8.1 µgP mg C-1. The
 herbivores showed a 10-fold growth rate difference among the diets. Growth
 rates related poorly with phosphorus content in the diets (r2=0.07),
 better with P ingestion rate (r2=0.41) and best with phosphorus
 assimilation rate (r2=0.69). Inclusion of assimilation rates for carbon
 and fatty acids increased 7% of the explained growth variance. These
 results indicate that the feeding and assimilation flexibilities play
 pivotal roles in acquiring a deficient element and in regulating growth
 rate.

title: Data from: Shrub expansion of Alnus viridis drives former montane grassland into nitrogen saturation

description: The N2-fixing shrub Alnus viridis is currently encroaching on montane
 grasslands in the Alps as a result of reduced land management and complete
 abandonment. Alnus introduces large amounts of nitrogen (N) into these
 formerly N-poor grasslands and restricts the succession to montane
 forests. We studied pools and fluxes of N and the associated C pools in
 pastures (controls) and adjacent Alnus shrublands at two elevations (1650
 versus 1950 m a.s.l.) in three valleys in the Swiss central Alps. The
 total N and C pools stored in 50-year-old Alnus shrubland did not exceed
 those in adjacent pastures with a total of approximately 610 g N m−2 in
 phytomass plus soil (down to 30 cm) at both elevations. In Alnus stands,
 reduced soil N pools balanced the gain in phytomass N pools, a likely
 result of a faster turnover of soil N. The soil solution under Alnus was
 continuously enriched with nitrate, with a total N leaching of 0.79 g N
 m−2 season−1 (June–October) under 50-year-old stands at both elevations
 and the highest flux of 1.76 g N m−2 season−1 in 25-year-old shrubland at
 low elevation, clearly indicating an excess of available N in Alnus
 shrubland. In contrast, N leaching across all pastures was close to zero
 (0.08 g N m−2) throughout the season. At the catchment scale, streamlet
 water showed increased nitrate concentrations with typical flushing peaks
 in spring and autumn, provided more than one fifth of the catchment area
 was covered by Alnus shrubs. We conclude that the expansion of Alnus
 rapidly converts centuries-old, N-poor grassland into N saturated
 shrubland, irrespective of elevation, and it reduces the C storage
 potential of the landscape because the Alnus dominance constrains
 re-establishment of a natural montane forest.

title: Data from: Local adaptation to developmental density does not lead to higher mating success in Drosophila melanogaster

description: In this study, we investigate the effect of local adaptation to
 developmental density on male mating success in laboratory populations of
 Drosophila melanogaster. Mating success is known to be influenced by body
 condition which can in turn be influenced by local adaptation. We test the
 hypothesis that males adapted to a given environment have higher mating
 success when assayed in that environment. We used males selected for
 adaptation to high larval density and their controls which are reared at
 low larval density. We grew assay males in low and high densities while
 the focal females (raised at low larval density) used for the experiment
 belonged to the common ancestor of selected and control populations. We
 considered selected males grown at high density and control males grown at
 low density as “adapted”. Similarly we considered selected males grown at
 low density and control males grown at high density as “non-adapted”.
 Selected male belonging to a given treatment (larval density) was made to
 compete with control male of the same treatment for mating with ancestral
 female. We quantified components of reproductive fitness: mating latency,
 copulation duration, mating success and number of progeny sired by the
 “adapted” and “non-adapted” males. The results show that local adaptation
 does not lead to higher mating success in populations adapted to their own
 larval rearing environment.

title: Data from: Testing models of sex ratio evolution in a gynodioecious plant: female frequency covaries with the cost of male fertility restoration

description: In many gynodioecious species, cytoplasmic male sterility genes (CMS) and
 nuclear male fertility restorers (Rf) jointly determine whether a plant is
 female or hermaphrodite. Equilibrium models of cytonuclear gynodioecy,
 which describe the effect of natural selection within populations on the
 sex ratio, predict that the frequency of females in a population will
 primarily depend on the cost of male fertility restoration, a negative
 pleiotropic effect of Rf alleles on hermaphrodite fitness. Specifically,
 when the cost of restoration is higher, the frequency of females at
 equilibrium is predicted to be higher. To test this prediction, we
 estimated variation in the cost of restoration across 26 populations of
 Lobelia siphilitica, a species in which Rf alleles can have negative
 pleiotropic effects on pollen viability. We found that L. siphilitica
 populations with many females were more likely to contain hermaphrodites
 with low pollen viability. This is consistent with the prediction that the
 cost of restoration is a key determinant of variation in female frequency.
 Our results suggest that equilibrium models can explain variation in sex
 ratio among natural populations of gynodioecious species.
