Significance In human populations, women live longer than men. While it is commonly assumed that this pattern of long-lived females vs. short-lived males constitutes the rule in mammals, magnitude sex differences lifespan and increase mortality rate with advancing age remain to be quantified. Here, we demonstrate that, wild, mammalian but did not detect any aging rates. Contrary a widespread hypothesis, reveal life history strategies do detectably influence either or Instead, our findings...
Comparative studies of trait evolution require accounting for the shared evolutionary history. This is done by including phylogenetic hypotheses into statistical analyses species' traits, which birds often serve as excellent models. The online publication most complete molecular phylogeny extant bird species (www.birdtree.org, BirdTree hereafter) now allows biologists to rapidly obtain sets equally plausible trees any set be incorporated a hypothesis in comparative analyses. We discuss...
By transforming landscapes, human activity creates new types of habitats with altered environmental characteristics that never existed before.As the process habitat urbanization bears impact on more and natural habitats, it is essential for us to understand changes we bring forth in ecological forces shaping urban animal communities.Birds are perhaps most frequently studied model organisms by ecologists.It a well known general pattern avian communities have typically reduced species...
Abstract Despite tremendous efforts in the past decades, relationships among main avian lineages remain heavily debated without a clear resolution. Discrepancies have been attributed to diversity of species sampled, phylogenetic method and choice genomic regions 1–3 . Here we address these issues by analysing genomes 363 bird 4 (218 taxonomic families, 92% total). Using intergenic coalescent methods, present well-supported tree but also marked degree discordance. The confirms that Neoaves...
1 Urbanized habitats differ from natural ones in several ecological features, including climate, food availability, strength of predation and competition. Although the effects urbanization on avian community composition are well known, there is much less information about how individual birds affected by these human-generated habitat differences. 2 In this study we investigated relationships between morphological characteristics degree house sparrows, Passer domesticus (Linne 1758) . We...
Is the cost of reproduction different between males and females? On one hand, typically compete intensely for mates, thus sexual selection theory predicts higher in species with intense male-male competition. other care provisioning such as incubating eggs raising young may also be costly, parental mortality care-giving sex, which is often female. We tested both hypotheses reproductive costs using phylogenetic comparative analyses sex-specific adult rates 194 bird across 41 families. First,...
Big brains are hypothesized to enhance survival of animals by facilitating flexible cognitive responses that buffer individuals against environmental stresses. Although this theory receives partial support from the finding brain size limits capacity behaviourally respond challenges, hypothesis large associated with reduced mortality has never been empirically tested. Using extensive information on avian adult natural populations, we show here species larger brains, relative their body size,...
Group living offers well-known benefits to animals, such as better predator avoidance and increased foraging success. An important additional, but so far neglected, advantage is that groups may cope more effectively with unfamiliar situations through faster innovations of new solutions by some group members. We tested this hypothesis experimentally presenting a task opening familiar feeder in an way house sparrows small large (2 versus 6 birds). size had strong effects on problem solving:...
Urbanization creates novel environments for wild animals where selection pressures may differ drastically from those in natural habitats. Adaptation to urban life involves changes various traits, including behavior. Behavioral traits often vary consistently among individuals, and these so-called personality can be correlated with each other, forming behavioral syndromes. Despite their adaptive significance potential act as constraints, little is known about the role of animal syndromes...
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...
Adult sex ratio (ASR) is a central concept in population demography and breeding system evolution, has implications for viability biodiversity conservation. ASR exhibits immense interspecific variation wild populations, although the causes of this have remained elusive. Using phylogenetic analyses 187 avian species from 59 families, we show that neither hatching ratios nor fledging correlate with ASR. However, sex-biased adult mortality significant predictor ASR, relationship robust to 100...
Urbanization can have marked effects on plant and animal populations' phenology, population size, predator-prey, interactions reproductive success. These aspects are rarely studied simultaneously in a single system, some investigated, e.g., how insect phenology responds to urban development. Here, we study tri-trophic system of trees, phytophagous insects (caterpillars), insectivorous birds (Great Tits) assess urbanization influences (1) the each component this (2) abundance, (3) avian We...
Animals living in urbanized habitats often show reduced fear responses to humans compared with their rural conspecifics. This is usually assumed be the result of habituation, but may also explained by differential colonization or local adaptation. To contrast these hypotheses, we studied urban and house sparrows (Passer domesticus) humans, measuring flight initiation distances (FID) free-living flocks observing hiding behavior wild-caught individuals response repeated human disturbance...
Abstract The altered ecological and environmental conditions in towns cities strongly affect demographic traits of urban animal populations, for example avian reproductive success is often reduced. Previous work suggests that this partly driven by low insect availability during the breeding season, but robust experimental evidence supports food limitation hypothesis not yet available. We tested core predictions using a controlled experiment provided supplementary (nutritionally enhanced...
Ecological conditions are likely to change with increasing urbanization, influencing the demography and size of animal populations. Although one most tightly linked species humans, house sparrow has been suffering a significant decline worldwide, especially in European cities. Several factors have proposed explain this conspicuous loss urban sparrows, but studies evaluating these usually restricted Britain where was very drastic, it is unclear whether similar or different processes affecting...
Innovative behaviors such as exploiting novel food sources can grant significant fitness benefits for animals, yet little is known about the mechanisms driving phenomena, and role of physiology virtually unexplored in wild species. Two hypotheses predict opposing effects physiological state on innovation success. On one hand, poor condition may promote innovations by forcing individuals with competitive abilities to invent alternative solutions. other superior ensure greater cognitive...
