title: Data from: Physiological adaptation along environmental gradients and replicated hybrid zone structure in swordtails (Teleostei: Xiphophorus)

description: Local adaptation is often invoked to explain hybrid zone structure, but
 empirical evidence of this is generally rare. Hybrid zones between two
 poeciliid fishes, Xiphophorus birchmanni and X. malinche, occur in
 multiple tributaries with independent replication of
 upstream-to-downstream gradients in morphology and allele frequencies.
 Ecological niche modelling revealed that temperature is a central
 predictive factor in the spatial distribution of pure parental species and
 their hybrids and explains spatial and temporal variation in the frequency
 of neutral genetic markers in hybrid populations. Among populations of
 parentals and hybrids, both thermal tolerance and heat-shock protein
 expression vary strongly, indicating that spatial and temporal structure
 is likely driven by adaptation to local thermal environments. Therefore,
 hybrid zone structure is strongly influenced by interspecific differences
 in physiological mechanisms for coping with the thermal environment.

title: Data from: Bioinvasion triggers rapid evolution of life-histories in freshwater snails

description: Biological invasions offer interesting situations to observe how novel
 interactions between closely related, formerly allopatric species may
 trigger phenotypic evolution in situ. Assuming that successful invaders
 are usually filtered to be competitively dominant, invasive and native
 species may follow different trajectories. Natives may evolve traits that
 minimize the negative impact of competition, while trait shifts in
 invasives should mostly reflect expansion dynamics, through selection for
 colonization ability and transiently enhanced mutation load at the
 colonization front. These ideas were tested through a large-scale
 common-garden experiment measuring life-history traits in two closely
 related snail species, one invasive and one native, co-occurring in a
 network of freshwater ponds in Guadeloupe. We looked for evidence of
 recent evolution by comparing uninvaded or recently invaded with
 long-invaded sites. The native species adopted a life history favoring
 rapid population growth (i.e. increased fecundity, earlier reproduction
 and increased juvenile survival) that may increase its prospects of
 coexistence with the more competitive invader. We discuss why these
 effects are more likely to result from genetic change than from maternal
 effects. The invader exhibited slightly decreased overall performances in
 recently colonized sites, consistent with a moderate expansion load
 resulting from local founder effects. Our study highlights a rare example
 of rapid life-history evolution following invasion.

title: Data from: The scent of attractiveness: levels of reproductive hormones explain individual differences in women’s body odour

description: Individuals are thought to have their own distinctive body odour which
 reportedly plays an important role in mate choice. In the present study we
 investigated individual differences in body odours of women and examined
 whether some women generally smell more attractive than others or whether
 odour preferences are a matter of individual taste. We then explored
 whether levels of reproductive hormones explain women’s body odour
 attractiveness, to test the idea that body odour attractiveness may act as
 a chemosensory marker of reproductive fitness. Fifty-seven men rated body
 odours of 28 healthy, naturally cycling women of reproductive age. We
 collected all odours at peak fertility to control for menstrual cycle
 effects on body odour attractiveness. Women’s salivary estradiol,
 progesterone, testosterone and cortisol levels were assessed at the time
 of odour collection to test whether hormone levels explain body odour
 attractiveness. We found that the men highly agreed on how attractive they
 found women’s body odours. Interestingly, women’s body odour
 attractiveness was predicted by their estradiol and progesterone levels:
 The higher a woman’s levels of estradiol and the lower her levels of
 progesterone, the more attractive her body odour was rated. In showing
 that women’s body odour attractiveness is explained by levels of female
 reproductive hormones, but not by levels of cortisol or testosterone, we
 provide evidence that body odour acts as a valid cue to potential
 fertility.

title: Data from: Plasmodium vivax diversity and population structure across four continents

description: Plasmodium vivax is the geographically most widespread human malaria
 parasite. To analyze patterns of microsatellite diversity and population
 structure across countries of different transmission intensity, genotyping
 data from 11 microsatellite markers was either generated or compiled from
 841 isolates from four continents collected in 1999–2008. Diversity was
 highest in South-East Asia (mean allelic richness 10.0–12.8), intermediate
 in the South Pacific (8.1–9.9) Madagascar and Sudan (7.9–8.4), and lowest
 in South America and Central Asia (5.5–7.2). A reduced panel of only 3
 markers was sufficient to identify approx. 90% of all haplotypes in South
 Pacific, African and SE-Asian populations, but only 60–80% in Latin
 American populations, suggesting that typing of 2–6 markers, depending on
 the level of endemicity, is sufficient for epidemiological studies.
 Clustering analysis showed distinct clusters in Peru and Brazil, but
 little sub-structuring was observed within Africa, SE-Asia or the South
 Pacific. Isolates from Uzbekistan were exceptional, as a near-clonal
 parasite population was observed that was clearly separated from all other
 populations (FST&gt;0.2). Outside Central Asia FST values were highest
 (0.11–0.16) between South American and all other populations, and lowest
 (0.04–0.07) between populations from South-East Asia and the South
 Pacific. These comparisons between P. vivax populations from four
 continents indicated that not only transmission intensity, but also
 geographical isolation affect diversity and population structure. However,
 the high effective population size results in slow changes of these
 parameters. This persistency must be taken into account when assessing the
 impact of control programs on the genetic structure of parasite
 populations.

title: Data from: The strength of migratory connectivity for birds en route to breeding through the Gulf of Mexico

description: The strength of migratory connectivity is a measure of the cohesion of
 populations among phases of the annual cycle, including breeding,
 migration, and wintering. Many Nearctic-Neotropical species have strong
 migratory connectivity between breeding and wintering phases of the annual
 cycle. It is less clear if this strength persists during migration when
 multiple endogenous and exogenous factors may decrease the cohesion of
 populations among routes or through time along the same routes. We sampled
 three bird species, American redstart (Setophaga ruticilla), ovenbird
 (Seiurus aurocapilla), and wood thrush (Hylocichla mustelina), during
 spring migration through the Gulf of Mexico region to test if breeding
 populations differentiate spatially among migration routes or temporally
 along the same migration routes and the extent to which within-population
 timing is a function of sex, age, and carry-over from winter habitat, as
 measured by stable carbon isotope values in claws (δ13C). To make
 quantitative comparisons of migratory connectivity possible, we developed
 and used new methodology to estimate the strength of migratory
 connectivity (MC) from probabilistic origin assignments identified using
 stable hydrogen isotopes in feathers (δ2H). We found support for spatial
 differentiation among routes by American redstarts and ovenbirds and
 temporal differentiation along routes by American redstarts. After
 controlling for breeding origin, the timing of American redstart migration
 differed among ages and sexes and ovenbird migration timing was influenced
 by carry-over from winter habitat. The strength of migratory connectivity
 did not differ among the three species, with each showing weak
 breeding-to-spring migration MC relative to prior assessments of
 breeding-wintering connectivity. Our work begins to fill an essential gap
 in methodology and understanding of the extent to which populations remain
 together during migration, information critical for a full annual cycle
 perspective on the population dynamics and conservation of migratory
 animals.

title: Data from: Satellite tracking reveals novel migratory patterns and the importance of seamounts for endangered South Pacific humpback whales

description: The humpback whale population of New Caledonia appears to display a novel
 migratory pattern characterized by multiple directions, long migratory
 paths and frequent pauses over seamounts and other shallow geographical
 features. Using satellite-monitored radio tags, we tracked 34 whales for
 between 5 and 110 days, travelling between 270 and 8540 km on their
 southward migration from a breeding ground in southern New Caledonia. Mean
 migration speed was 3.53±2.22 km h−1, while movements within the breeding
 ground averaged 2.01±1.63 km h−1. The tag data demonstrate that seamounts
 play an important role as offshore habitats for this species. Whales
 displayed an intensive use of oceanic seamounts both in the breeding
 season and on migration. Seamounts probably serve multiple and important
 roles as breeding locations, resting areas, navigational landmarks or even
 supplemental feeding grounds for this species, which can be viewed as a
 transient component of the seamount communities. Satellite telemetry
 suggests that seamounts represent an overlooked cryptic habitat for the
 species. The frequent use by humpback whales of such remote locations has
 important implications for conservation and management.

title: Data from: Niche partitioning and the role of intraspecific niche variation in structuring a guild of generalist anurans

description: Intra-population niche differences in generalist foragers have captured
 the interest of ecologists, because such individuality can have important
 ecological and evolutionary implications. Few researchers have
 investigated how these differences affect the relationships among
 ecologically similar, sympatric species. Using stable isotopes, stomach
 contents, morphology and habitat preference, we examined niche
 partitioning within a group of five anurans and determined whether
 variation within species could facilitate resource partitioning. Species
 partitioned their niches by trophic level and by foraging habitat.
 However, there was considerable intraspecific variation in trophic level,
 with larger individuals generally feeding at higher trophic levels. For
 species at intermediate trophic levels, smaller individuals overlapped in
 trophic level with individuals of smaller species and larger individuals
 overlapped with the smallest individuals from larger species. Species
 varied in carbon isotopes; species with enriched carbon isotope ratios
 foraged farther from ponds, whereas species with depleted carbon isotope
 values foraged closer to ponds. Our study shows that these species
 partition their niches by feeding at different trophic levels and foraging
 at different distances from ponds. The intraspecific variation in trophic
 level decreased the number of individuals from each species that
 overlapped in trophic level with individuals from other species, which can
 facilitate species coexistence.

title: Data from: Multidimensionality in host manipulation mimicked by serotonin injection

description: Manipulative parasites often alter the phenotype of their hosts along
 multiple dimensions. ‘Multidimensionality’ in host manipulation could
 consist in the simultaneous alteration of several physiological pathways
 independently of one another, or proceed from the disruption of some key
 physiological parameter, followed by a cascade of effects. We compared
 multidimensionality in ‘host manipulation’ between two closely related
 amphipods, Gammarus fossarum and Gammarus pulex, naturally and
 experimentally infected with Pomphorhynchus laevis (Acanthocephala),
 respectively. To that end, we calculated in each host–parasite association
 the effect size of the difference between infected and uninfected
 individuals for six different traits (activity, phototaxis, geotaxis,
 attraction to conspecifics, refuge use and metabolic rate). The effects
 sizes were highly correlated between host–parasite associations, providing
 evidence for a relatively constant ‘infection syndrome’. Using the same
 methodology, we compared the extent of phenotypic alterations induced by
 an experimental injection of serotonin (5-HT) in uninfected G. pulex to
 that induced by experimental or natural infection with P. laevis. We
 observed a significant correlation between effect sizes across the six
 traits, indicating that injection with 5-HT can faithfully mimic the
 ‘infection syndrome’. This is, to our knowledge, the first experimental
 evidence that multidimensionality in host manipulation can proceed, at
 least partly, from the disruption of some major physiological mechanism.

title: Data from: High gene flow on a continental scale in the polyandrous Kentish Plover Charadrius alexandrinus

description: Gene flow promotes genetic coherence of species in time and space. It can
 be modulated by sex-biased dispersal which links population genetics to
 mating systems. We investigated the phylogeography of the widely
 distributed Kentish plover Charadrius alexandrinus. This small shorebird
 has a large breeding range spanning from Western Europe to Japan, and
 exhibits an unusually flexible mating system with high female breeding
 dispersal. We analyzed genetic structure and gene flow using a 427 bp
 fragment of the mitochondrial (mtDNA) control region, 21 autosomal
 microsatellite markers and a Z microsatellite marker in 363 unrelated
 individuals from 21 locations. We found no structure or
 isolation-by-distance over the continental range. However, island
 populations had low genetic diversity, and were moderately differentiated
 from mainland locations. Genetic differentiation based on autosomal
 markers was positively correlated with distance between mainland and each
 island. Comparisons of uniparentally and biparentally inherited markers
 were consistent with female-biased gene flow. Maternally inherited mtDNA
 was less structured whereas the Z-chromosomal marker was more structured
 than autosomal microsatellites. Adult males were more related than females
 within genetic clusters. Taken together, our results suggest a prominent
 role for polyandrous females in maintaining genetic coherence across large
 geographic distances.

title: Data from: Sleep apnea, sleep debt and daytime sleepiness are independently associated with road accidents: a cross-sectional study on truck drivers

description: Background: Recent research has found evidence of an association between
 motor vehicle accidents (MVAs) or near miss accidents (NMAs), and
 excessive daytime sleepiness (EDS) or its main medical cause, Obstructive
 Sleep Apnea (OSA). However, EDS can also be due to non-medical factors,
 such as sleep debt (SD), which is common among professional truck drivers.
 On the opposite side, rest breaks and naps are known to protect against
 accidents. Study objectives: To investigate the association of OSA, SD,
 EDS, rest breaks and naps, with the occurrence of MVAs and NMAs in a large
 sample of truck drivers. Methods: 949 male truck drivers took part in a
 cross-sectional medical examination and were asked to complete a
 questionnaire about sleep and waking habits, risk factors for OSA and EDS.
 Results: MVAs and NMAs were reported by 34.8% and 9.2% of participants,
 respectively. MVAs were significantly predicted by OSA (OR= 2.32
 CI95%=1.68-3.20), SD (OR=1.45 CI95%=1.29-1.63), EDS (OR=1.73
 CI95%=1.15-2.61) and prevented by naps (OR=0.59 CI95%=0.44-0.79) or rest
 breaks (OR=0.63 CI95%=0.45-0.89). NMAs were significantly predicted by OSA
 (OR= 2.39 CI95%=1.47- 3.87) and SD (OR=1.49 CI95%=1.27- 1.76) and
 prevented by naps (OR=0.52 CI95%=0.32- 0.85) or rest breaks (OR=0.49
 CI95%=0.29- 0.82). Conclusions: When OSA, SD or EDS are present, the risk
 of MVAs or NMAs in truck drivers is severely increased. Taking a rest
 break or a nap appear to be protective against accidents.

title: Data from: Conflict between biotic and climatic selective pressures acting on an extended phenotype in a subarctic, but not temperate, environment

description: Climatic selective pressures are thought to dominate biotic selective
 pressures at higher latitudes. However, few studies have experimentally
 tested how these selective pressures differentially act on traits across
 latitudes because traits can rarely be manipulated independently of the
 organism in nature. We overcame this challenge by using an extended
 phenotype—active bird nests—and conducted reciprocal transplant
 experiments between a subarctic and temperate site, separated by 14° of
 latitude. At the subarctic site, biotic selective pressures (nest
 predation) favoured smaller, non-local temperate nests, whereas climatic
 selective pressures (temperature) favoured larger local nests,
 particularly at colder temperatures. By contrast, at the temperate site,
 climatic and biotic selective pressures acted similarly on temperate and
 subarctic nests. Our results illustrate a functional trade-off in the
 subarctic between nest morphologies favoured by biotic versus climatic
 selective pressures, with climate favouring local nest morphologies. At
 our temperate site, however, allocative trade-offs in the time and effort
 devoted to nest construction favour smaller, local nests. Our findings
 illustrate a conflict between biotic and climatic selective pressures at
 the northern extremes of a species geographical range, and suggest that
 trade-offs between trait function and trait elaboration act differentially
 across latitude to create broad geographic variation in traits.

title: Data from: With a little help from my kin: barn swallow nestlings modulate solicitation of parental care according to nestmates’ need

description: In altricial species, offspring competing for access to limiting parental
 resources (e.g. food) are selected to achieve an optimal balance between
 the costs of scrambling for food, the benefits of being fed and the
 indirect costs of subtracting food to relatives. Since the marginal
 benefits of acquiring additional food decrease with decreasing levels of
 need, satiated offspring should be prone to favour access to food by their
 needy kin, thus enhancing their own indirect fitness, while concomitantly
 reducing costs of harsh competition with hungry broodmates. We tested this
 prediction in feeding trials of barn swallow (Hirundo rustica) nestlings
 by comparing begging behaviour and food intake of two similar-sized
 nestmates, one of which was food-deprived (FD). Non-food-deprived (NFD)
 offspring modulated begging intensity depending on their nestmate’s need:
 when competing with FD nestmates, NFD nestlings reduced both the intensity
 and frequency of begging displays compared to themselves in the control
 trial before food deprivation. Hence, NFD nestlings reduced their
 competitiveness to the advantage of FD nestmates, which obtained more
 feedings and showed a three-fold larger increase in body mass. Moderation
 of individual selfishness can therefore be adaptive in presence of a
 needier kin, because the indirect fitness benefits of promoting its
 condition can outweigh the costs of forgoing being fed, and because it
 limits the cost of begging escalation against a vigorous competitor.

title: Data from: Costs and benefits of sub-lethal Drosophila C virus infection

description: Viruses are major evolutionary drivers of insect immune systems. Much of
 our knowledge of insect immune responses derives from experimental
 infections using the fruit fly Drosophila melanogaster. Most experiments,
 however, employ lethal pathogen doses through septic injury, frequently
 overwhelming host physiology. While this approach has revealed several
 immune mechanisms, it is less informative about the fitness costs hosts
 may experience during infection in the wild. Using both systemic and oral
 infection routes we find that even apparently benign, sub-lethal
 infections with the horizontally transmitted Drosophila C Virus (DCV) can
 cause significant physiological and behavioral morbidity that is relevant
 for host fitness. We describe DCV-induced effects on fly reproductive
 output, digestive health, and locomotor activity, and we find that viral
 morbidity varies according to the concentration of pathogen inoculum, host
 genetic background and sex. Notably, sub-lethal DCV infection resulted in
 a significant increase in fly reproduction, but this effect depended on
 host genotype. We discuss the relevance of sub-lethal morbidity for
 Drosophila ecology and evolution, and more broadly, we remark on the
 implications of deleterious and beneficial infections for the evolution of
 insect immunity.
