title: Data from: Corticosterone predicts foraging behavior and parental care in macaroni penguins

description: Corticosterone has received considerable attention as the principal
 hormonal mediator of allostasis or physiological stress in wild animals.
 More recently, it has also been implicated in the regulation of parental
 care in breeding birds, particularly with respect to individual variation
 in foraging behaviour and provisioning effort. There is also evidence that
 prolactin can work either inversely or additively with corticosterone to
 achieve this. Here we test the hypothesis that endogenous corticosterone
 plays a key physiological role in the control of foraging behaviour and
 parental care using a combination of exogenous corticosterone treatment,
 time-depth telemetry, and physiological sampling of female macaroni
 penguins (Eudyptes chrysolophus) during the brood-guard period of chick
 rearing, while simultaneously monitoring patterns of prolactin secretion.
 Plasma corticosterone levels were significantly higher in females given
 exogenous implants relative to those receiving sham implants. Increased
 corticosterone levels were associated with significantly higher levels of
 foraging and diving activity, and greater mass gain in implanted females.
 Elevated plasma corticosterone was also associated with an apparent
 fitness benefit in the form of increased chick mass. Plasma prolactin
 levels did not correlate with corticosterone levels at any time, nor was
 prolactin correlated with any measure of foraging behaviour or parental
 care. Our results provide support for the corticosterone-adaptation
 hypothesis, which predicts that higher corticosterone levels support
 increased foraging activity and parental effort.

title: Data from: Assessing the alignment of sexual and natural selection using radio-mutagenized seed beetles

description: A major unsolved question in evolutionary biology concerns the
 relationship between natural and sexual selection. Sexual selection might
 augment natural selection, e.g. if mutations that harm female fecundity
 also reduce male mating success. Conversely, sexual selection might favor
 traits that impair naturally-selected fitness components. We induced
 detrimental mutations in Callosobruchus maculatus beetles using X-ray
 irradiation, and then experimentally measured the effect of pre-copulatory
 sexual selection on offspring number and survival rate. Sexual selection
 treatment had a negative effect on egg-to-adult survivorship, though the
 number of progeny reaching adulthood was unaffected, perhaps because eggs
 and juveniles that failed to develop lessened competition on the
 survivors. We hypothesize that the negative effect of sexual selection
 arose because sexually competitive males transmitted a smaller nuptial
 gift, or carried alleles that conferred reduced survival. Although we
 found no evidence that sexual selection on males can purge alleles that
 are detrimental to naturally-selected fitness components, such benefits
 might exist in other environmental or genetic contexts.

title: Data from: Beyond thermal performance curves: modeling time-dependent effects of thermal stress on ectotherm growth rates

description: Thermal performance curves have been widely used to model the ecological
 responses of ectotherms to variable thermal environments and climate
 change. Such models ignore the effects of time dependence—the temporal
 pattern and duration of temperature exposure—on performance. We developed
 and solved a simple mathematical model for growth rate of ectotherms,
 combining thermal performance curves for ingestion rate with the temporal
 dynamics of gene expression and protein production in response to high
 temperatures to predict temporal patterns of growth rate in constant and
 diurnally fluctuating temperatures. We used the model to explore the
 effects of heat shock proteins on larval growth rates of Manduca sexta.
 The model correctly captures two empirical patterns for larval growth
 rate: first, maximal growth rate and optimal temperature decline with
 increasing duration of temperature exposure; second, mean growth rates
 decline with time in diurnally fluctuating temperatures at higher mean
 temperatures. These qualitative results apply broadly to cases where
 proteins or other molecules produced in response to high temperatures
 reduce growth rates. We discuss some of the critical assumptions and
 predictions of the model and suggest potential extensions and
 alternatives. Incorporating time-dependent effects will be essential for
 making more realistic predictions about the physiological and ecological
 consequences of temperature fluctuations and climate change.

title: Data from: Stomatopods detect and assess achromatic cues in contests

description: Conspicuous, colorful displays are often used by animals to communicate
 within and between species. Previously, researchers have manipulated
 specific components of color signals (i.e., hue, total reflectance, and/or
 chroma) using paints, photographs, videos, or filters. However, these
 manipulations may not adequately mimic the spectrum of color signals
 outside the range of human perception. Thus, these methods are
 inappropriate for organisms with unconventional visual systems, such as
 stomatopods (mantis shrimp). Here, we describe a novel application of a
 femtosecond laser to increase total reflectance of the stomatopod meral
 spot, a distinct area on the raptorial appendage used in territorial
 contests. Ultrafast lasers provide a programmable way to precisely
 manipulate patch total reflectance of live stomatopods without causing
 collateral damage. We tested how experimentally increasing meral spot
 reflectance impacted receiver behavior during territorial contests.
 Contests in which receiver stomatopods faced an opponent with a lightened
 meral spot were shorter and receivers showed increased rates of agonistic
 behaviors. This result suggests that lighter meral spots indicate lower
 fighting ability; thus, receivers are more willing to engage in a contest.
 This research provides the first demonstration that stomatopods can detect
 and assess achromatic variation in contests. Furthermore, we demonstrate
 that ultrafast lasers provide a powerful tool to investigate achromatic
 signaling, particularly for organisms whose size, aquatic habitat, or
 visual system otherwise prevent realistic alterations to color signals
 (e.g., butterflies, jumping spiders, or decapod crustaceans). This study
 advances our knowledge about stomatopod visual communication and offers a
 valuable tool for future research.

title: Data from: Experimental evidence that the effectiveness of conservation biological control depends on landscape complexity

description: 1. The expansion of intensive agricultural practices is a major threat to
 biodiversity and to the delivery of ecosystem services on which humans
 depend. Local-scale conservation management strategies, such as
 agri-environment schemes to preserve biodiversity, have been widely
 adopted to reduce the negative impacts of agricultural intensification.
 However, it is likely that the effectiveness of these local-scale
 management actions depend on the structure and composition of the
 surrounding landscape. 2. We experimentally tested the utility of floral
 resource strips to improve local-scale biological control of crop pests,
 when placed within a gradient of moderately simple through to highly
 complex landscapes. 3. We found that experimental provision of floral
 resources enhanced parasitism rates of two globally important crop pests
 in moderately simple landscapes but not in highly complex ones, and this
 translated into reduced pest abundances and increased crop yield. 4.
 Synthesis and applications. Our results lend experimental support for the
 ‘intermediate landscape complexity hypothesis’, which predicts that local
 conservation management will be most effective in moderately simple
 agricultural landscapes, and less effective in either very simple
 landscapes where there is no capacity for response, or in highly complex
 landscapes where response potential is already saturated. This knowledge
 will allow more targeted and cost-effective implementation of conservation
 biological control programs based on an improved understanding of
 landscape-dependent processes, which will reduce the negative impacts of
 agricultural intensification.

title: Data from: Interactive effects between physical forces and ecosystem engineers on seed burial: a case study using Spartina anglica

description: Seed burial (i.e. vertical seed dispersal) has become increasingly valued
 for its relevance for seed fate and plant recruitment. While ecosystem
 engineers have been generally considered as the most important drivers of
 seed burial, the role of physical forces, such as wind or water flow, has
 been largely overlooked. Using tidal habitats as a model system, and a
 combination of flume and mesocosm experiments, we investigated the effects
 of 1) currents, 2) benthic animals with different engineering activities
 and 3) their interplay on seed burial of a common salt marsh pioneer
 plant, Spartina anglica. Our results reveal that in such systems, water
 flow can be of equal or higher importance than ecosystem engineers for
 seed burial. For passive seed-burying engineers (PSE), coupling their
 actions with currents produced synergistic seed burial effects, whereas
 the interactive effects were only additive for active seed-burying
 engineers (ASE). This paper extends current understanding of seed burial
 and seed bank formation by revealing the need to incorporate physical
 forces into seed burial mechanisms. We provide the first empirical
 evidence that physical forces influence seed burial by synergistically
 interacting with ecosystem engineers, thus highlighting the role of
 biophysical interactions as important drivers for vertical seed movement.

title: Data from: Investment in territorial defence relates to recent reproductive success in common loons Gavia immer

description: As the value of a limited resource such as a territory increases, animals
 should invest more in the defence of that resource. Because reproductive
 success often depends on the quality of a breeding territory, reproductive
 success or failure may alter the perceived value of territory and affect
 an animal's investment in territorial defence. We used common loons
 (Gavia immer) to test the hypothesis that animals with recent breeding
 success would show stronger territorial defence than those with no recent
 breeding success. Surprisingly, successful loons responded less, not more,
 to a simulated intrusion. However, birds with success in the previous
 season also increased their territorial response as the breeding season
 progressed. In conjunction with past data showing that recently successful
 loons experience an increase in conspecific intrusions on their
 territories, we interpret our data to suggest that loons with recent
 success offset the cost of increased intrusions by adopting a more
 efficient strategy for territorial defence (e.g., limiting investment in
 resource defence until the time of the season when it is most critical).

title: Data from: Relationship between maternal environment and DNA methylation patterns of estrogen receptor alpha in wild Eastern Bluebird (Sialia sialis) nestlings: a pilot study

description: There is mounting evidence that, across taxa, females breeding in
 competitive environments tend to allocate more testosterone to their
 offspring prenatally and these offspring typically have more aggressive
 and faster-growing phenotypes. To date, no study has determined the
 mechanisms mediating this maternal effect's influence on offspring
 phenotype. However, levels of estrogen receptor alpha (ERα) gene
 expression are linked to differences in early growth and aggression; thus,
 maternal hormones may alter gene regulation, perhaps via DNA methylation,
 of ERα in offspring during prenatal development. We performed a pilot
 study to examine natural variation in testosterone allocation to offspring
 through egg yolks in wild Eastern Bluebirds (Sialia sialis) in varying
 breeding densities and percent DNA methylation of CG dinucleotides in the
 ERα promoter in offspring brain regions associated with growth and
 behavior. We hypothesized that breeding density would be positively
 correlated with yolk testosterone, and prenatal exposure to
 maternal-derived yolk testosterone would be associated with greater
 offspring growth and decreased ERα promoter methylation. Yolk testosterone
 concentration was positively correlated with breeding density, nestling
 growth rate, and percent DNA methylation of one out of five investigated
 CpG sites (site 3) in the diencephalon ERα promoter, but none in the
 telencephalon (n = 10). Percent DNA methylation of diencephalon CpG site 3
 was positively correlated with growth rate. These data suggest a possible
 role for epigenetics in mediating the effects of the maternal environment
 on offspring phenotype. Experimentally examining this mechanism with a
 larger sample size in future studies may help elucidate a prominent way in
 which animals respond to their environment. Further, by determining the
 mechanisms that mediate maternal effects, we can begin to understand the
 potential for the heritability of these mechanisms and the impact that
 maternal effects are capable of producing at an evolutionary scale.

title: Data from: Exploring the impact of multidecadal environmental changes on the population genetic structure of a marine primary producer

description: Many marine protists form resting stages that can remain viable in coastal
 sediments for several decades. Their long-term survival offers the
 possibility to explore the impact of changes in environmental conditions
 on population dynamics over multidecadal time scales. Resting stages of
 the phototrophic dinoflagellate Pentapharsodinium dalei were isolated and
 germinated from five layers in dated sediment cores from Koljö fjord,
 Sweden, spanning ca. 1910–2006. This fjord has, during the last century,
 experienced environmental fluctuations linked to hydrographic variability
 mainly driven by the North Atlantic Oscillation. Population genetic
 analyses based on six microsatellite markers revealed high genetic
 diversity and suggested that samples belonged to two clusters of
 subpopulations that have persisted for nearly a century. We observed
 subpopulation shifts coinciding with changes in hydrographic conditions.
 The large degree of genetic diversity and the potential for both
 fluctuation and recovery over longer time scales documented here, may help
 to explain the long-term success of aquatic protists that form resting
 stages.

title: Data from: Matrix correspondence tests on the DNA phylogeny of the Tenerife lacertid elucidate both historical causes and morphological adaptation

description: Previous studies using partial regression Mantel tests of matrix
 correspondence on within-island geographic variation in the color pattern
 of the Tenerife (Canary Islands) lacertid lizard (Gallotia galloti)
 support natural selection for different north--south climatically
 determined biotopes but do not support any historical cause. However,
 tests on the DNA phylogeny based primarily on population data from 57
 localities on Tenerife support the hypothesis that there were populations
 on two putative precursor islands that have come into secondary contact
 and introgressed after these islands were joined to form Tenerife by the
 eruption of the Canadas edifice. Subsequent partial Mantel tests continue
 to support the hypothesis that color pattern is adapted to the climatic
 biotopes even when this phylogenetic information is taken into account by
 (1) testing for color pattern adaptation separately within each lineage
 and (2) testing for color pattern adaptation across the entire island
 while considering the molecular phylogenetic relationships as representing
 an alternative explanation. Selection has largely expunged any trace of
 the geological history from current morphological variation, and the
 introgression of these island populations after an estimated 0.7 million
 years of separation gives an insight into the relationships between
 allopatric divergence and reproductive isolation.

title: Data from: Imprinting can cause a maladaptive preference for infectious conspecifics

description: Recognizing and associating with specific individuals, such as
 conspecifics or kin, brings many benefits. One mechanism underlying such
 recognition is imprinting: the long-term memory of cues encountered during
 development. Typically, juveniles imprint on cues of nearby individuals
 and may later associate with phenotypes matching their ‘recognition
 template’. However, phenotype matching could lead to maladaptive social
 decisions if, for instance, individuals imprint on the cues of
 conspecifics infected with directly transmitted diseases. To investigate
 the role of imprinting in the sensory ecology of disease transmission, we
 exposed juvenile guppies, Poecilia reticulata, to the cues of healthy
 conspecifics, or to those experiencing disease caused by the directly
 transmitted parasite Gyrodactylus turnbulli. In a dichotomous choice test,
 adult ‘disease-imprinted’ guppies preferred to associate with the chemical
 cues of G. turnbulli-infected conspecifics, whereas ‘healthy-imprinted’
 guppies preferred to associate with cues of uninfected conspecifics. These
 responses were only observed when stimulus fish were in late infection,
 suggesting imprinted fish responded to cues of disease, but not of
 infection alone. We discuss how maladaptive imprinting may promote disease
 transmission in natural populations of a social host.
