title: Data from: Effects of warming rate, acclimation temperature and ontogeny on the critical thermal maximum of temperate marine fish larvae

description: Most of the thermal tolerance studies on fish have been performed on
 juveniles and adults, whereas limited information is available for larvae,
 a stage which may have a particularly narrow range in tolerable
 temperatures. Moreover, previous studies on thermal limits for marine and
 freshwater fish larvae (53 studies reviewed here) applied a wide range of
 methodologies (e.g. the static or dynamic method, different exposure
 times), making it challenging to compare across taxa. We measured the
 Critical Thermal Maximum (CTmax) of Atlantic herring (Clupea harengus) and
 European seabass (Dicentrarchus labrax) larvae using the dynamic method
 (ramping assay) and assessed the effect of warming rate (0.5 to 9°C h-1)
 and acclimation temperature. The larvae of herring had a lower CTmax
 (lowest and highest values among 222 individual larvae, 13.1 – 27.0 °C)
 than seabass (lowest and highest values among 90 individual larvae, 24.2 –
 34.3 °C). At faster rates of warming, larval CTmax significantly increased
 in herring, whereas no effect was observed in seabass. Higher acclimation
 temperatures led to higher CTmax in herring larvae (2.7 ± 0.9°C increase)
 with increases more pronounced at lower warming rates. Pre-trials testing
 the effects of warming rate are recommended. Our results for these two
 temperate marine fishes suggest using a warming rate of 3 - 6 °C h-1:
 CTmax is highest in trials of relatively short duration, as has been
 suggested for larger fish. Additionally, time-dependent thermal tolerance
 was observed in herring larvae, where a difference of up to 8°C was
 observed in the upper thermal limit between a 0.5- or 24-h exposure to
 temperatures &gt;18°C. The present study constitutes a first step
 towards a standard protocol for measuring thermal tolerance in larval
 fish.

title: Data from: Ectoparasites and fitness of female Columbian ground squirrels

description: Parasites play an important role in the evolution of host traits via
 natural selection, coevolution and sexually selected ornaments used in
 mate choice. These evolutionary scenarios assume fitness costs for hosts.
 To test this assumption, we conducted an ectoparasite removal experiment
 in free-living Columbian ground squirrels (Urocittelus columbianus) in
 four populations over three years. Adult females were randomly chosen to
 be either experimentally treated with anti-parasite treatments (spot-on
 solution and flea powder, N = 61) or a sham treatment (control, N = 44).
 We expected that experimental females would show better body condition,
 increased reproductive success and enhanced survival. Contrary to our
 expectations, body mass was not significantly different between treatments
 at mating, birth of litter or weaning of young. Further, neither number
 nor size of young at weaning differed significantly between the two
 treatments. Survival to the next spring for adult females and juveniles
 was not significantly different between experimental and control
 treatments. Finally, annual fitness was not affected by the treatments. We
 concluded that females and their offspring were able compensate for the
 presence of ectoparasites, suggesting little or no fitness costs of
 parasites for females in the different colonies and during the years of
 our experiments.

title: Data from: The hidden cost of sexually selected traits: the metabolic expense of maintaining a sexually selected weapon

description: Sexually selected weapons are among the most exaggerated traits in nature.
 Theory frequently assumes a high cost of this exaggeration; yet, those
 costs are rarely measured. We know very little about the energetic
 resources required to maintain these traits at rest and the difference in
 energetic costs for the largest relative to the smallest individuals.
 Knowledge in this area is crucial; resting metabolic rate can account for
 30-40% of daily energy expenditure in wild animals. Here, we capitalized
 on the phenomenon of autotomy to take a unique look at weapon maintenance
 costs. Using Leptoscelis tricolor (Hemiptera: Coreidae) we measured CO2
 production rates before and after a weapon was shed. Males in this insect
 species use enlarged hind femora as weapons in male-male combat, and yet
 can shed them readily, without regeneration, upon entrapment. We found
 that metabolic rate decreased by an average of 23.5% in males after leg
 loss and by 7.9% in females. Notably, larger males had less of a drop in
 metabolic rate per gram of weapon lost. Our findings suggest sexually
 selected weapons contribute to a large portion of resting metabolic rate
 in males, but these costs do not scale in direct proportion to size;
 larger males can have larger weapons for a reduced metabolic cost. These
 energetic maintenance costs may be integral to the evolution of the
 allometries of sexually selected weapons, and yet they remain largely
 unexplored.

title: Data from: Retracted: Experimental evidence that maternal corticosterone controls adaptive offspring sex ratios

description: THIS ARTICLE HAS BEEN RETRACTED 1. Sex allocation theory has received
 considerable attention, yet the mechanism(s) by which mothers skew
 offspring sex ratios remain unknown. In birds, females are the
 heterogametic sex, which potentially gives them control of whether gametes
 will be male or female. How females might control the sex of the gamete is
 unclear, but one possibility is that variation in steroid hormones may
 mediate this process. 2. We experimentally altered circulating levels of
 corticosterone in female Gouldian finches (Erythrura gouldiae), a species
 that demonstrates both extreme stress responses and extreme offspring sex
 ratio biases when breeding with a low-quality (genetically-incompatible)
 partner. 3. During egg production, individual females received both
 corticosterone and metyrapone (a corticosterone-synthesis inhibitor)
 implants, in random order, to induce both high and low levels of
 circulating stress hormones (within physiological limits). 4. We found
 that females with elevated corticosterone levels produced male-biased sex
 ratios, but when the same females were treated with metyrapone they
 produced female-biased offspring sex ratios. 5. These stress responses are
 adaptive because females constrained to breeding with low-quality males
 can substantially increase their fitness by overproducing sons. Changes in
 maternal corticosterone levels during stressful situations, such as the
 quality of a breeding partner, may provide an endocrine mechanism that can
 be exploited for strategic sex allocation.

title: Data from: The effects of short term detraining and retraining on physical fitness in elite soccer players

description: Purpose: The aim of this study was to examine the effects of aerobic
 high-intensity training with reduced volume and training cessation on body
 composition and physical fitness after the end of season and the time
 required to recapture physical fitness with intensified retraining
 following two weeks of detraining in elite soccer players. Method: Twenty
 male semi-professional soccer players participated in this study. The
 soccer players were assigned to either a group that completed
 high-intensity aerobic training (HAT, n = 10) or to a detraining and
 retraining group (DHAT, n = 10) for a 5-week period immediately after the
 end of the season. The first 2 weeks of the period, members of the HAT
 group performed high-intensity aerobic exercise (80–90% of HRmax, 12 min ×
 3, three times per week), whereas members of the DHAT group abstained from
 any physical activity. During the subsequent 3 weeks, members of both the
 HAT and DHAT groups completed high-intensity aerobic exercise. Exercise
 performance testing and body composition analysis were performed before;
 after 2 weeks of detraining; and at 1, 2 and 3 weeks of retraining.
 Results: Intensified high-intensity training for 5 weeks maintained the
 performance in the Yo-Yo Intermittent Recovery level 2 test (Yo-Yo IR2)
 and repeated sprints at any time point (P &gt; 0.05). However 2 weeks
 of detraining resulted in significant decreases in the performance on the
 Yo-Yo IR2 (P &lt; 0.01) and repeated sprints test (P &lt; 0.05).
 Performance on the Yo-Yo IR2 enhanced after 2 weeks of retraining and was
 maintained up to 3 weeks after retraining, with no significant differences
 between conditions (P &gt; 0.05). In addition, repeated sprint
 performance markedly decreased after the detraining period (P &lt;
 0.05) and was continuously lower compared to the baseline at 2 weeks after
 retraining (P &lt; 0.05). Furthermore, this value reached baseline
 level at the end of the experimental period (P &gt; 0.05). There were
 no significant differences between conditions in body composition,
 performance of agility, or sprint ability throughout the 5-week
 experimental period (P &gt; 0.05). Conclusions: The present data
 suggest that short-term detraining after the competitive season can
 markedly decrease performances in the Yo-Yo IR2 test and repeated sprints.
 To return to a previous level of ability on the Yo-Yo IR2 and/or sprint
 test with retraining through high-intensity aerobic training after a
 period of detraining, a similar or longer period of retraining is
 required. However, the high-intensity training with reduced amount of
 training after competitive season can prevent reductions in physical
 fitness.

title: Data from: Convergence in resource use efficiency across trees with differing hydraulic strategies in response to ecosystem precipitation manipulation

description: 1. Plants are expected to respond to drought by maximizing the efficiency
 of the most limiting resource, the water use efficiency (WUE), at the
 expense of nitrogen and carbon use efficiencies (NUE and CUE). Therefore,
 plants resource use efficiencies are viewed as indicators of species
 drought tolerance. 2. We tested these predictions by measuring leaf-level
 intrinsic WUE (WUEi, the ratio of net assimilation to stomatal
 conductance), photosynthetic NUE (PNUE, the ratio of daily maximum net
 assimilation to leaf nitrogen content) and leaf-scale CUE (approached by
 the ratio of nighttime respiration to daytime net assimilation, Rd/An) in
 piñon pine and juniper, two tree species that differ in drought tolerance
 and vulnerability to drought-induced mortality. Variations in resource use
 efficiency in the two species were measured in response to seasonal
 drought and in response to an ecosystem-scale precipitation manipulation
 experiment comprising three precipitation treatments: ambient, irrigation
 (+30%) and partial rainfall exclusion (-45%). 3. Increasing water
 limitation, either seasonally or across treatments, resulted in increased
 WUE and decreased PNUE and CUE in both species. WUE, PNUE and CUE varied
 more strongly in response to water limitation than across species and
 converged to the same relationships against precipitation for piñon and
 juniper. 4. Plasticity in WUE, PNUE and CUE in response to water
 limitation was associated, in both species, with low carbon acquisition
 during drought. Our results exhibited a convergence in resource use
 efficiency across piñon and juniper which contradicts the paradigm that
 resource use efficiencies are indicators of species drought tolerance and
 ecological strategy.

title: Data from: Cascading effects of defaunation on the coexistence of two specialized insect seed predators

description: Identification of the mechanisms enabling stable coexistence of species
 with similar resource requirements is a central challenge in ecology. Such
 coexistence can be facilitated by species at higher trophic levels through
 complex multi-trophic interactions, a mechanism that could be compromised
 by ongoing defaunation. We investigated cascading effects of defaunation
 on Pachymerus cardo and Speciomerus giganteus, the specialized insect seed
 predators of the Neotropical palm Attalea butyracea, testing the
 hypothesis that vertebrate frugivores and granivores facilitate their
 coexistence. Laboratory experiments showed that the two seed parasitoid
 species differed strongly in their reproductive ecology. Pachymerus
 produced many small eggs that it deposited exclusively on the fruit
 exocarp (exterior). Speciomerus produced few large eggs that it deposited
 exclusively on the endocarp, which is normally exposed only after a
 vertebrate handles the fruit. When eggs of the two species were deposited
 on the same fruit, Pachymerus triumphed only when it had a long head
 start, and the loser always succumbed to intraguild predation. We
 collected field data on the fates of 6569 Attalea seeds across sites in
 central Panama with contrasting degrees of defaunation and wide variation
 in the abundance of vertebrate frugivores and granivores. Speciomerus
 dominated where vertebrate communities were intact, whereas Pachymerus
 dominated in defaunated sites. Variation in the relative abundance of
 Speciomerus across all 84 sampling sites was strongly positively related
 to the proportion of seeds attacked by rodents, an indicator of local
 vertebrate abundance. Synthesis. We show that two species of insect seed
 predators relying on the same host plant species are niche differentiated
 in their reproductive strategies such that one species has the advantage
 when fruits are handled promptly by vertebrates and the other when they
 are not. Defaunation disrupts this mediating influence of vertebrates and
 strongly favours one species at the expense of the other, providing a case
 study of the cascading effects of defaunation and its potential to disrupt
 coexistence of non-target species, including the hyperdiverse phytophagous
 insects of tropical forests.

title: Data from: Origins of the Greenland shark (Somniosus microcephalus): impacts of ice-olation and introgression

description: Herein, we use genetic data from 277 sleeper sharks to perform
 coalescent-based modeling to test the hypothesis of early Quaternary
 emergence of the Greenland shark (Somniosus microcephalus) from ancestral
 sleeper sharks in the Canadian Arctic-Subarctic region. Our results show
 that morphologically cryptic somniosids S. microcephalus and Somniosus
 pacificus can be genetically distinguished using combined mitochondrial
 and nuclear DNA markers. Our data confirm the presence of genetically
 admixed individuals in the Canadian Arctic and sub-Arctic, and temperate
 Eastern Atlantic regions, suggesting introgressive hybridization upon
 secondary contact following the initial species divergence. Conservative
 substitution rates fitted to an Isolation with Migration (IM) model
 indicate a likely species divergence time of 2.34 Ma, using the
 mitochondrial sequence DNA, which in conjunction with the geographic
 distribution of admixtures and Pacific signatures likely indicates
 speciation associated with processes other than the closing of the Isthmus
 of Panama. This time span coincides with further planetary cooling in the
 early Quaternary period followed by the onset of oscillating
 glacial-interglacial cycles. We propose that the initial S.
 microcephalus–S. pacificus split, and subsequent hybridization events,
 were likely associated with the onset of Pleistocene glacial oscillations,
 whereby fluctuating sea levels constrained connectivity among Arctic
 oceanic basins, Arctic marginal seas, and the North Atlantic Ocean. Our
 data demonstrates support for the evolutionary consequences of oscillatory
 vicariance via transient oceanic isolation with subsequent secondary
 contact associated with fluctuating sea levels throughout the Quaternary
 period—which may serve as a model for the origins of Arctic marine fauna
 on a broad taxonomic scale.

title: Data from: Children's visuospatial memory predicts mathematics achievement through early adolescence

description: A previous study showed that gains in visuospatial memory from first to
 fifth grade predicted end-of-fifth grade mathematics but not reading
 achievement, controlling other factors. In this follow up study, these
 relations were assessed from sixth to ninth grade, inclusive (n = 145).
 The results showed that growth in visuospatial memory across the
 elementary school years was related to growth in mathematics achievement
 after fifth grade, controlling intelligence, the central executive and
 phonological memory components of working memory, in-class attentive
 behavior, parental education, and fifth grade mathematics achievement. As
 found for fifth grade, this relation was not found for reading achievement
 after fifth grade. In total, the results suggest that visuospatial memory
 has a unique influence on ease of learning some types of mathematics and
 that this influence becomes more important across successive grades.

title: Data from: Quantifying predator dependence in the functional response of generalist predators

description: A long-standing debate concerns how functional responses are best
 described. Theory suggests that ratio dependence is consistent with many
 food web patterns left unexplained by the simplest prey-dependent models.
 However, for logistical reasons, ratio dependence and predator dependence
 more generally have seen infrequent empirical evaluation and then only so
 in specialist predators, which are rare in nature. Here we develop an
 approach to simultaneously estimate the prey-specific attack rates and
 predator-specific interference (facilitation) rates of predators
 interacting with arbitrary numbers of prey and predator species in the
 field. We apply the approach to surveys and experiments involving two
 intertidal whelks and their full suite of potential prey. Our study
 provides strong evidence for predator dependence that is poorly described
 by the ratio dependent model over manipulated and natural ranges of
 species abundances. It also indicates how, for generalist predators, even
 the qualitative nature of predator dependence can be prey-specific.
