Parental care often increases offspring survival, but is costly to the parents. A trade-off between cost and benefit of expected, so that when provisioning by both parents essential for success young, instance in extremely cold or hot environments, should rear their young together. We investigated latter hypothesis a ground nesting shorebird, Kentish plover Charadrius alexandrinus an environment, Arabian Desert. Midday temperature was above 50°C our study site Abu Dhabi (United Arab...
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...
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...
. Charadrii (shorebirds, gulls, and alcids) have an unusual diversity in their sexual size dimorphism, ranging from monomorphism to either male‐biased or female‐biased dimorphism. We use comparative analyses investigate whether this variation relates selection through competition for mates natural different of resources by males females. As predicted theory, we found that taxa with socially polygynous mating systems, were relatively larger than females compared less species. Furthermore,...
Sexual size dimorphism shows a remarkably widespread relationship to body in the animal kingdom: within lineages, it decreases with when females are larger sex, but increases males sex. Here we demonstrate that this pattern, termed Rensch's rule, exists shorebirds and allies (Charadriides), is determined by two components of sexual selection: intensity selection acting on agility males' display. These effects interactive so effect depends male agility. As control, also examine bill length,...
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,...
In 1950, Rensch first described that in groups of related species, sexual size dimorphism is more pronounced larger species. This widespread and fundamental allometric relationship now commonly referred to as ‘Rensch's rule’. However, despite numerous recent studies, we still do not have a general explanation for this allometry. Here report patterns allometry over 5300 bird species demonstrate Rensch's rule driven by correlated evolutionary change females directional selection on males....
Genetically identical cells frequently display substantial heterogeneity in gene expression, cellular morphology and physiology. It has been suggested that by rapidly generating a subpopulation with novel phenotypic traits, (or plasticity) accelerates the rate of adaptive evolution populations facing extreme environmental challenges. This issue is important as cell-to-cell may initiate key steps microbial drug resistance cancer progression. Here, we study how stochastic transitions between...
Abstract Environmental variability has long been postulated as a major selective force in the evolution of large brains. However, assembling evidence for this hypothesis proved difficult. Here, by combining brain size information over 1,200 bird species with remote-sensing analyses to estimate temporal variation ecosystem productivity, we show that larger brains (relative body size) are more likely occur exposed environmental throughout their geographic range. Our reconstructions...
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...
We review the conservation issues facing migratory shorebird populations that breed in temperate regions and use wetlands non‐breeding season. Shorebirds are excellent model organisms for understanding ecological, behavioural evolutionary processes often used as indicators of wetland health. A global team experienced researchers identified 45 these populations, divided them into three categories (natural, current anthropogenic future issues). The natural included megatsunamis, volcanoes...
