title: Data from: Experimentally induced repeated anhydrobiosis in the eutardigrade Richtersius coronifer

description: Tardigrades represent one of the main animal groups with anhydrobiotic
 capacity at any stage of their life cycle. The ability of tardigrades to
 survive repeated cycles of anhydrobiosis has rarely been studied but is of
 interest to understand the factors constraining anhydrobiotic survival.
 The main objective of this study was to investigate the patterns of
 survival of the eutardigrade Richtersius coronifer in tardigrades under
 repeated cycles of desiccation, and the potential effect of repeated
 desiccation on size, shape and number of storage cells. We also analyzed
 potential change in body size, gut content and frequency of mitotic
 storage cells. Specimens were kept under non-cultured conditions and
 desiccated under controlled relative humidity. After each desiccation
 cycle 10 specimens were selected for analysis of morphometric
 characteristics and mitosis. The study demonstrates that tardigrades may
 survive up to 6 repeated desiccations, with declining survival rates with
 increased number of desiccations. We found a significantly higher
 proportion of animals that were unable to contract properly into a tun
 stage during the desiccation process at the 5th and 6th desiccations. Also
 total number of storage cells declined at the 5th and 6th desiccations,
 while no effect on storage cell size was observed. The frequency of
 mitotic storage cells tended to decline with higher number of desiccation
 cycles. Our study shows that the number of consecutive cycles of
 anhydrobiosis that R. coronifer may undergo is limited, with increased
 inability for tun formation and energetic constraints as possible causal
 factors.

title: Data from: Intraspecific variation in body size does not alter the effects of mesopredators on prey

description: As humans continue to alter the species composition and size structure of
 marine food webs, it is critical to understand size-dependent effects of
 predators on prey. Yet, how shifts in predator body size mediate the
 effect of predators is understudied in tropical marine ecosystems, where
 anthropogenic harvest has indirectly increased the density and size of
 small-bodied predators. Here, we combine field surveys and a laboratory
 feeding experiment in coral reef fish communities to show that small and
 large predators of the same species can have similar effects.
 Specifically, surveys show that the presence of a small predator
 (Paracirrhites arcatus) was correlated with lower chances of prey fish
 presence, but these correlations were independent of predator size.
 Experimental trials corroborated the size-independent effect of the
 predator; attack rates were indistinguishable between small and large
 predators, suggesting relatively even effects of hawkfish in various size
 classes on the same type of prey. Our results indicate that the effects of
 small predators on coral reefs can be size-independent, suggesting that
 variation in predator size-structure alone may not always affect the
 functional role of these predators.

title: Data from: Lower carotid revascularization rates after stroke in ethnic minority-serving US hospitals

description: Objective: We sought to determine whether the use of carotid
 revascularization procedures after stroke due to carotid stenosis differs
 between minority-serving hospitals and hospitals serving predominantly
 white patients. Methods: We identified ischemic stroke cases due to
 carotid disease, identified by ICD9-CM codes, from 2007-2011 in the
 Nationwide Inpatient Sample. The use of carotid endarterectomy (CEA) and
 carotid artery stenting (CAS) was recorded. Hospitals with ≥40% ethnic
 minority patients (minority-serving hospitals) were compared to hospitals
 with &lt;40% minority patients (white hospitals). Logistic regression
 was used to evaluate the use of CEA/CAS among minority-serving and white
 hospitals. Results: Of the 26,189 ischemic stroke cases meeting inclusion
 criteria, 20,870 (79.7%) were treated at 1,113 white hospitals, and 5,319
 (20.3%) received care at 325 hospitals minority-serving hospitals.
 Compared to patients in white hospitals, patients in minority hospitals
 were less likely to undergo CEA/CAS (17.6%, 95% CI 16.6%-18.6%, in
 minority vs. 21.2%, 95% CI 20.7%-21.8%, in white hospitals,
 p&lt;0.001). In fully adjusted logistic regression models, the odds of
 CEA/CAS were lower in minority compared to white hospitals (OR 0.81, 95%
 CI 0.70-0.93), independent of individual patient race and other measured
 hospital characteristics. Whites and Hispanics had significantly lower
 odds of CEA/CAS in minority compared to white hospitals. Patient-level
 racial differences in the use of carotid revascularization procedures
 remained within each hospital stratum. Conclusions: The odds of carotid
 revascularization after stroke is lower in minority-serving compared to
 white hospitals, suggesting system-level factors as a major contributor to
 explain race disparities in the use of carotid revascularization.

title: Data from: Dynamic analysis of liquid annular seals with herringbone grooves on the rotor based on perturbation method

description: Annular seals have significant effects on the hydraulic and rotordynamic
 performances turbomachinery. In this paper, an analysis method for
 calculating the leakage rate and dynamic characterisitcs of liquid annular
 seals with herringbone grooves on the rotor is proposed and verified.
 Leakage flow rates and dynamic characteristics of the model seals under
 different operating conditions are theoretically analyzed and compared to
 those of the plain and spiral-grooved seals of the same size. Besides, the
 influence of geometric parameters such as spiral angle and the lengths of
 the constituent parts on the sealing and rotordynamic coefficients of
 seals with herringbone grooves are also discussed in this paper. The
 results show that seals with herringbone grooves have better sealing
 performance, while providing bigger support actions and better damping
 characteristics than the other two seal types under the same operating
 conditions. The seal geometric parameters including spiral angle, the
 lengths of the constituent parts and the clearance value have great
 influence on the dynamic characteristics of seals with herringbone
 grooves.

title: Data from: Quantifying episodes of sexual selection: insights from a transparent worm with fluorescent sperm

description: Sexual selection operates through consecutive episodes of selection that
 ultimately contribute to the observed variance in reproductive success
 between individuals. Understanding the relative importance of these
 episodes is challenging, particularly because the relevant post-copulatory
 fitness components are often difficult to assess. Here we investigate
 different episodes of sexual selection on the male sex function, by
 assessing how (pre-copulatory) mating success, and (post-copulatory)
 sperm-transfer efficiency and sperm-fertilising efficiency contribute to
 male reproductive success. Specifically, we used a transgenic line of the
 transparent flatworm, Macrostomum lignano, which expresses green
 fluorescent protein (GFP) in all cell types, including sperm cells,
 enabling in vivo sperm tracking and paternity analysis. We found that a
 large proportion of variance in male reproductive success arose from the
 post-copulatory episodes. Moreover, we also quantified selection
 differentials on ten morphological traits. Testis size and seminal vesicle
 size showed significant positive selection differentials, which were
 mainly due to selection on sperm-transfer efficiency. Overall, our results
 demonstrate that male reproductive success in M. lignano is not primarily
 limited by the number of matings achieved, but rather by the ability to
 convert matings into successful fertilisations, which is facilitated by
 producing many sperm.

title: Data from: Development and field validation of a regional, management-scale habitat model: a koala Phascolarctos cinereus case study

description: Species distribution models have great potential to efficiently guide
 management for threatened species, especially for those that are rare or
 cryptic. We used MaxEnt to develop a regional-scale model for the koala
 Phascolarctos cinereus at a resolution (250 m) that could be used to guide
 management. To ensure the model was fit for purpose, we placed emphasis on
 validating the model using independently-collected field data. We reduced
 substantial spatial clustering of records in coastal urban areas using a
 2-km spatial filter and by modeling separately two subregions separated by
 the 500-m elevational contour. A bias file was prepared that accounted for
 variable survey effort. Frequency of wildfire, soil type, floristics and
 elevation had the highest relative contribution to the model, while a
 number of other variables made minor contributions. The model was
 effective in discriminating different habitat suitability classes when
 compared with koala records not used in modeling. We validated the MaxEnt
 model at 65 ground-truth sites using independent data on koala occupancy
 (acoustic sampling) and habitat quality (browse tree availability). Koala
 bellows (n = 276) were analyzed in an occupancy modeling framework, while
 site habitat quality was indexed based on browse trees. Field validation
 demonstrated a linear increase in koala occupancy with higher modeled
 habitat suitability at ground-truth sites. Similarly, a site habitat
 quality index at ground-truth sites was correlated positively with modeled
 habitat suitability. The MaxEnt model provided a better fit to estimated
 koala occupancy than the site-based habitat quality index, probably
 because many variables were considered simultaneously by the model rather
 than just browse species. The positive relationship of the model with both
 site occupancy and habitat quality indicates that the model is fit for
 application at relevant management scales. Field-validated models of
 similar resolution would assist in guiding management of
 conservation-dependent species.

title: Data from: A novel, bounding gait in swimming turtles: implications for aquatic locomotor diversity

description: Turtles are an iconic lineage in studies of animal locomotion, typifying
 the use of slow, alternating footfalls during walking. Alternating
 movements of contralateral limbs are also typical during swimming gaits
 for most freshwater turtles. Here, we report a novel gait in turtles, in
 which the pleurodire Emydura subglobosa swims using a bounding gait that
 coordinates bilateral protraction of both forelimbs with bilateral
 retraction of both hindlimbs. Use of this bounding gait is correlated with
 increased limb excursion and decreased stride frequency, but not increased
 velocity when compared to standard swimming strokes. Bounding by E.
 subglobosa provides a second example of a non-mammalian lineage that can
 use bounding gaits, and may give insight into the evolution of aquatic
 flapping. Parallels in limb muscle fascicle properties between bounding
 turtles and crocodylids suggest a possible musculoskeletal mechanism
 underlying the use of bounding gaits in particular lineages.

title: Data from: Internet blogs, polar bears, and climate-change denial by proxy

description: Increasing surface temperatures, Arctic sea-ice loss, and other evidence
 of anthropogenic global warming (AGW) are acknowledged by every major
 scientific organization in the world. However, there is a wide gap between
 this broad scientific consensus and public opinion. Internet blogs have
 strongly contributed to this consensus gap by fomenting misunderstandings
 of AGW causes and consequences. Polar bears (Ursus maritimus) have become
 a “poster species” for AGW, making them a target of those denying AGW
 evidence. Here, focusing on Arctic sea ice and polar bears, we show that
 blogs that deny or downplay AGW disregard the overwhelming scientific
 evidence of Arctic sea-ice loss and polar bear vulnerability. By denying
 the impacts of AGW on polar bears, bloggers aim to cast doubt on other
 established ecological consequences of AGW, aggravating the consensus gap.
 To counter misinformation and reduce this gap, scientists should directly
 engage the public in the media and blogosphere.

title: Data from: Experimental evidence for within- and cross-seasonal effects of fear on survival and reproduction

description: Fear of predation can have non-lethal effects on individuals within a
 season but whether, and to what extent, these effects carry over into
 subsequent seasons is not known. Using a replicated seasonal population of
 the common fruit fly, Drosophila melanogaster, we examined both within-
 and cross-seasonal effects of fear on survival and reproductive output.
 Compared to controls, flies exposed to the scent of mantid (Tenodera
 sinensis) predators in the non-breeding season had 64% higher mortality,
 and lost 60% more mass by the end of the non-breeding season and, in the
 subsequent breeding season, produced 20% fewer offspring that weighed 9%
 less at maturity. Flies exposed to the scent of mantids in the breeding
 season did not produce fewer offspring, but their offspring developed
 faster and weighed less as adults compared to the controls. Our results
 demonstrate how effects of fear can be manifested both within and across
 seasons and emphasize the importance of understanding how events
 throughout the annual cycle influence individual success of animals living
 in seasonal environments.

title: Data from: Hybridization increases mitochondrial production of reactive oxygen species in sunfish

description: Mitochondrial dysfunction and oxidative stress have been suggested to be
 possible mechanisms underlying hybrid breakdown, as a result of
 mito-nuclear incompatibilities in respiratory complexes of the electron
 transport system. However, it remains unclear whether hybridization
 increases the production of reactive oxygen species (ROS) by mitochondria.
 We used high-resolution respirometry and fluorometry on isolated liver
 mitochondria to examine mitochondrial physiology and ROS emission in
 naturally occurring hybrids of pumpkinseed (Lepomis gibbosus) and bluegill
 (L. macrochirus). ROS emission was greater in hybrids than in both parent
 species when respiration was supported by complex I (but not complex II)
 substrates, and was associated with increases in lipid peroxidation.
 However, respiratory capacities for oxidative phosphorylation,
 phosphorylation efficiency, and O2 kinetics in hybrids were intermediate
 between those in parental species. Flux control ratios of capacities for
 electron transport (measured in uncoupled mitochondria) relative to
 oxidative phosphorylation suggested that the limiting influence of the
 phosphorylation system is reduced in hybrids. This likely helped offset
 impairments in electron transport capacity and complex III activity, but
 contributed to augmenting ROS production. Therefore, hybridization can
 increase mitochondrial ROS production, in support of previous suggestions
 that mitochondrial dysfunction can induce oxidative stress and thus
 contribute to hybrid breakdown.

 physiology of bluegill (Lepomis macrochirus), pumpkinseed (Lepomis
 gibbosus), and their hybrids were assessed. Mitochondrial respiration was

title: Data from: Optimizing methods for PCR-based analysis of predation

description: Molecular methods have become an important tool for studying feeding
 interactions under natural conditions. Despite their growing importance,
 many methodological aspects have not yet been evaluated but need to be
 considered to fully exploit the potential of this approach. Using feeding
 experiments with high alpine carabid beetles and lycosid spiders, we
 investigated how PCR annealing temperature affects prey DNA detection
 success and how post-PCR visualization methods differ in their
 sensitivity. Moreover, the replicability of prey DNA detection among
 individual PCR assays was tested using beetles and spiders that had
 digested their prey for extended times postfeeding. By screening all
 predators for three differently sized prey DNA fragments (range 116–612
 bp), we found that only in the longest PCR product, a marked decrease in
 prey detection success occurred. Lowering maximum annealing temperatures
 by 4 °C resulted in significantly increased prey DNA detection rates in
 both predator taxa. Among the three post-PCR visualization methods, an
 eightfold difference in sensitivity was observed. Repeated screening of
 predators increased the total number of samples scoring positive, although
 the proportion of samples testing positive did not vary significantly
 between different PCRs. The present findings demonstrate that assay
 sensitivity, in combination with other methodological factors, plays a
 crucial role to obtain robust trophic interaction data. Future work
 employing molecular prey detection should thus consider and minimize the
 methodologically induced variation that would also allow for better
 cross-study comparisons.

title: Data from: Assessing the efficacy and ecology of biocontrol and biomanipulation for managing invasive pest fish

description: 1. Management of non-native species aims to prevent biological invasions
 using actions including control and containment of the potential invader.
 Biocontrol and biomanipulation strategies are used frequently to reduce
 population sizes of non-native species and reduce their ecological impacts
 and dispersal rates. 2. Assessments of the efficacy of biocontrol and
 biomanipulation actions for managing non-native pest fish, and the
 ecological mechanisms involved, were studied here using lentic populations
 of the invasive fish Pseudorasbora parva. Biocontrol was through release
 of the indigenous piscivorous fish Perca fluviatilis and biomanipulation
 through intensive fish removals. 3. A combined biocontrol and removal
 programme was completed in an invaded pond over two reproductive seasons.
 Almost 10 000 P. parva were removed, with cumulative removal numbers
 significantly related to their decreased abundance (&gt;60 to
 &lt;0·1 m−2). Ten adult P. fluviatilis were also released initially
 and reproduced each season. Analyses revealed P. parva contribution to P.
 fluviatilis diet was high initially, but decreased as P. parva abundance
 reduced. Individual contributions of the management actions to declined P.
 parva abundance were difficult to isolate. 4. The individual effects of
 biocontrol and removals on P. parva populations were then tested using a
 field trial in replicated pond mesocosms over three reproductive seasons.
 Replicates started with 1500 P. parva. The control (no interventions)
 revealed no significant temporal changes in P. parva abundances. In the
 removal treatment, where over 17 000 P. parva were removed per replicate
 over the trial, abundance declined initially, but increased significantly
 after each reproductive season as remaining fish compensated through
 increased reproductive output. In the biocontrol, abundance declined and
 remained low; analyses revealed P. parva were an important dietary
 component of larger P. fluviatilis, with predation suppressing
 compensatory responses. 5. Synthesis and applications. Biocontrol and
 removals can significantly reduce abundances of lentic populations of
 small invasive fishes. Removals provide short-term population suppression,
 but high effort is needed to overcome compensatory responses. Biocontrol
 can provide longer-term suppression but could invoke unintended ecological
 consequences via ‘stocking-up’ food webs. Application of these results to
 decision-making frameworks should enable managers to make more objective
 decisions on risk-commensurate methodologies for controlling small
 invasive fishes.
