Understanding the causes and consequences of variation in rate recombination is essential since this parameter considered to affect levels genetic variability, efficacy selection, design association linkage mapping studies. However, there limited knowledge about factors governing variation. We genotyped 1920 single nucleotide polymorphisms a multigeneration pedigree more than 1000 zebra finches ( Taeniopygia guttata ) develop map, then we used these map data together with recently available...
In many species that form socially monogamous pair bonds, a considerable proportion of the offspring is sired by extrapair males. This observation has remained puzzle for evolutionary biologists: although mating outside bond can obviously increase production males, benefits such behavior to females are less clear, yet known actively solicit copulations. For more than two decades adaptionist explanations have dominated discussions, remain controversial, and genetic constraint arguments been...
Abstract Lower visibility of female scientists, compared to male is a potential reason for the under‐representation women among senior academic ranks. Visibility in scientific community stems partly from presenting research as an invited speaker at organized meetings. We analysed sex ratio presenters E uropean S ociety volutionary B iology ( ESEB ) C ongress 2011, where all abstract submissions were accepted presentation. Women under‐represented speakers symposia (15% women) (46%), regular...
The classical version of the differential allocation hypothesis states that, when females reproduce over their lifetime with partners that differ in genetic quality, they should invest more reproduction high-quality males. However, species monogamy, such as zebra finch, partner quality will typically remain same. In this case, compensatory investment (CI) predicts higher for low-quality males, because low offspring are dependent on maternal resources. Here, we show female finches invested...
The recent demographic transitions to lower mortality and fertility rates in most human societies have led changes even quick reversals phenotypic selection pressures. This can only result evolutionary change if the affected traits are heritable, but environmental conditions may also lead subsequent genetic variance covariance (the G matrix) of traits. It currently remains unclear there been concomitant matrix life-history following transition. Using 300 years genealogical data from Finland,...
Life history theory has become a prominent framework in the evolutionary social sciences, and concept of trade-offs, cornerstone life studies on non-human taxa, likewise been widely adopted. Yet, human research often assumes trade-offs without demonstrating them. This is not surprising given practical difficulties measuring long-lived animals, like humans. Four main methods are used to demonstrate trade-offs: phenotypic correlations, experimental manipulations, genetic correlations...
Abstract The causes underlying sex differences in lifespan are strongly debated. While females commonly outlive males humans, this is generally less pronounced societies before the demographic transition to low mortality and fertility rates. Life-history theory suggests that reduced reproduction should benefit female when pay higher costs of than males. Using unique longitudinal records on 140,600 reproducing individuals from Utah Population Database, we demonstrate a shift male-biased...
The developmental stress hypothesis offers a mechanism to maintain honesty of sexually selected ornaments, because only high quality individuals will be able develop full ornamentation in the face during early development. Experimental tests this have traditionally involved manipulation one aspect rearing conditions and an examination effects on adult traits. Here, we instead use statistically powerful quantitative genetic approach detect condition dependence. We animal models estimate...
Consistent between-individual differences in context-general behavioral traits (often called personality traits) are particularly interesting for ecologists because they might show unexpected cross-context correlations and explain maladaptive behavior. In order to understand their evolutionary significance, it is relevant know the heritability of these how relate reproductive success. This give insights into selective processes that maintain variation as well potential trade-offs. We scored...
Theoretical and empirical literature asserts that the sex ratio (i.e. M/F) at birth gauges strength of selection in utero cohort quality males survive to birth. We report first individual-level test humans, using detailed life-history data, 'culled cohort' hypothesis born low annual cohorts show lower than expected infant mortality greater lifetime reproductive success. applied time-series structural equation methods a unique multigenerational dataset natural fertility population nineteenth...
The sexes often have different phenotypic optima for important life-history traits, and because of a largely shared genome this can lead to conflict over trait expression. In mammals, the obligate costs reproduction are higher females, making reproductive timing rate especially liable between sexes. While studies from wild vertebrates support such sexual conflict, it remains unexplored in humans. We used pedigreed human population preindustrial Finland estimate age at first last...
Abstract Variation in sex differences is affected by both genetic and environmental variation, with rapid change being more likely due to change. One case of human lifespan, which has become increasingly female‐biased recent centuries. Long‐term consequences variation the early‐life environment may, part, explain such differences, but whether mediates life‐history traits poorly understood animals. Combining longitudinal data on 60 cohorts pre‐industrial Finns data, we show that associated...
Sexual imprinting on discrete variation that serves the identification of species, morphs or sexes is well documented. By contrast, sexual continuous leading to individual differences in mating preferences within a single morph and sex has been studied only once (in humans). We measured female captive population wild-type zebra finches. Individual cross-fostering ensured all subjects grew up with unrelated foster parents nest mates. Females from two cohorts (N = 113) were given simultaneous...
Many species show substantial between-individual variation in mating preferences, but studying the causes of such remains a challenge. For example, relative importance heritable versus shared early environment effects (like sexual imprinting) on preferences has never been quantified population animals. Here, we estimate heritability and rearing mate choice decisions zebra finches based similarity choices between pairs genetic sisters raised apart unrelated foster sisters. We found low...
Abstract Human impact does not only affect the abundances of fish, but also age- and size-distributions. Indicators fish age size-structures can hence be useful tools for fisheries- environmental management. Size-based indicators have been tested proposed large, homogenous marine ecosystems with high fishing mortality, rarely fine-scaled heterogeneous in coastal zones. Here we analyse a suite size communities Baltic Sea, including mean median length, 10th 90th-percentile length distribution...
It is a common observation in evolutionary studies that larger, more ornamented or earlier breeding individuals have higher fitness, but body size, ornamentation time does not change despite of sometimes substantial heritability for these traits. A possible explanation this traits do causally affect rather happen to be indirectly correlated with fitness via unmeasured non-heritable aspects condition (e.g. undernourished offspring grow small and low as adults due poor health). Whether applies...
Sexual dimorphism in life history traits and their trade-offs is widespread among sexually reproducing animals strongly influenced by the differences reproductive strategies between sexes. We investigated how intrasexual competition specific traits, important to fitness outcrossing nematode Caenorhabditis remanei. Here, we altered strength of sex-specific selection through experimental evolution with increased potential for skewing adult sex ratio towards either females or males (1:10 10:1)...
Abstract Evolution in fluctuating environments is predicted to disfavor specialization and instead select for alternative strategies, such as phenotypic plasticity or possibly bet-hedging, depending on the accuracy of environmental cues type fluctuations. While these two alternatives are often contrasted theoretical studies, their evolution seldom studied together empirical work. We used experimental nematode worm Caenorhabditis remanei simultaneously study bet-hedging differing only...
