Abstract Adaptive integration of life history and behaviour is expected to result in variation the pace‐of‐life. Previous work focused on whether ‘risky’ phenotypes live fast but die young, reported conflicting support. We posit that individuals exhibiting risky may alternatively invest heavily early‐life reproduction consequently suffer greater reproductive senescence. used a 7‐year longitudinal dataset with >1,200 breeding records >800 female great tits assayed annually for...
The integration and synthesis of the data in different areas science is drastically slowed hindered by a lack standards networking programmes. Long-term studies individually marked animals are not an exception. These especially important as instrumental for understanding evolutionary ecological processes wild. Furthermore, their number global distribution provides unique opportunity to assess generality patterns address broad-scale issues (e.g. climate change). To solve enable new scale...
Predation induces strong selection on phenotypic traits, affecting prey via consumptive and nonconsumptive effects. Communication is important for territorial behavior, but can increase susceptibility to predators. Therefore, predation risk should influence communication patterns, territoriality, fitness. We evaluated how this trade-off resolved 2 manipulations of perceived using audio playback in wild great tits ( Parus major ). In the first experiment, we examined immediate response...
Remarkable variation in animal colour patterns is often shaped by heterogeneous selection, reflecting adaptation to variable environmental conditions. However, the adaptive functions of and drivers selection remain poorly understood. Shape size may help with thermoregulation thus be altered temperature anomalies, which are predicted more frequent current climate change. Using resighting data from 810 individuals over eight years, we studied effects spot on survival a population wild giraffes...
Optimal life-history decisions are shaped by prevailing environmental conditions. In the context of urbanization, differences between urban and rural areas known to vary across a multitude axes. The relative roles specific axes whether they explain variation in avian life histories forest city populations have not often been studied empirically. This study comprehensively views urbanization from multidimensional perspective. For each 13 nest box plots common passerine bird (the great tit...
Natural selection often favors particular combinations of functionally-related traits, resulting in adaptive phenotypic integration. Phenotypic integration has been proposed as a potential mechanism explaining the existence repeatable among-individual differences behavior (i.e., animal personality). In this study, we investigated patterns covariation between morphology and population free-living great tits (Parus major) monitored for 7 years. particular, aimed to disentangle effect...
Significance A key question in behavioral ecology is whether individual differences behavior are adaptive rather than merely representing “noise around an mean.” We show strong evidence for spatial and temporal variation survival recruitment selection both within among West European great tit ( Parus major ) populations, implying that spatiotemporal environmental conditions contributes to the maintenance of animal personality variation. The majority variance was attributable large-scale...
Males of socially monogamous species can increase their siring success via within-pair and extra-pair fertilizations. In this study, we focused on the different sources (co)variation between these routes, asked how each contributes to total success. We quantified fertilization routes success, as well behaviors that have been hypothesized affect over a five-year period for wild population great tits Parus major. considered its "interactive phenotypes" arising from phenotypic contributions...
Abstract A major question in behavioural ecology is why behaviour, physiology and morphology are often integrated into syndromes. In great tits, Parus , for example, explorative males larger (vs. smaller) leaner heavier) compared to less individuals. Unfortunately, considerable debate exists on whether patterns found specific studies replicable. This calls study replication among species, populations sexes. We measured (exploration), physiological (breathing rate) morphological traits (body...
Abstract Conclusions about the adaptive nature of repeatable variation in behavior (i.e., “personality”) are often derived from laboratory-based assays. However, expression genetic differs between laboratory and field. Laboratory-based might not predict field-based thus, cross-context validation is required. We estimated correlation expressed by wild great tits (Parus major) established versus field novel environment Both assays have been used as proxies for “exploration tendency.” Behavior...
Abstract Ecological factors and individual-specific traits affect parasite infestation in wild animals. Ixodid ticks are important ectoparasites of various vertebrate hosts, which include passerine bird species such as the great tit ( Parus major ). We studied key ecological variables (breeding density, human disturbance) phenotypic (exploratory behaviour, body condition) proposed to predict tick probability burden tits. Our study spanned 3 years 12 nest box plots located southern Germany....
Abstract Non‐consumptive predator effects have been shown to influence a wide range of behavioural, life history and morphological traits. Extra‐pair reproduction is widespread among socially monogamous birds may incur predation costs. Consequently, altered rates extra‐pair are expected in circumstances characterized by increased adult perceived risk. In addition, be most affected for with phenotypes that generally increase risk (such as more active individuals). two consecutive years, was...
Dynamical tunneling is a quantum phenomenon where classically forbidden process occurs that prohibited not by energy but another constant of motion. The dynamical has been recently observed in sodium Bose-Einstein condensate. We present detailed analysis these experiments using numerical solutions the three-dimensional Gross-Pitaevskii equation and corresponding Floquet theory. explore parameter dependency oscillations we move system towards classical limit experimentally accessible regime.
Abstract Predictable behaviour (or ‘behavioural stability’) might be favoured in certain ecological contexts, for example when representing a quality signal. Costs associated with producing stable phenotypes imply selection should favour plasticity stability beneficial. Repeatable among‐individual differences degree of are simultaneously expected if individuals differ ability to pay these costs, or how they resolve cost–benefit trade‐offs. Bird song represents prime example, where may costly...
Abstract Ticks are important vectors of human and animal pathogens, but many questions remain unanswered regarding their taxonomy. Molecular sequencing methods have allowed research to start understanding the evolutionary history even closely related tick species. Ixodes inopinatus is considered a sister species highly similar ricinus , an vector tick-borne pathogens in Europe, identification between these remains ambiguous with disagreement on geographic extent I. . In 2018-2019, 1583 ticks...
SUMMARY Testosterone is involved in the development and expression of physiological, morphological behavioural traits. High levels are often associated with high infection risk and/or intensity, suggesting a trade-off between sexual traits immunity. Classically invoked mechanisms immunological or behavioural, i.e., testosterone increases susceptibility resistance to parasites via an impact on immunity modulates behaviours parasite transmission. However, studies report contrasted patterns....
Abstract In various taxa, multibroodedness is a common breeding strategy. Life-history theory predicts that individuals can increase fitness by producing multiple broods within season. Despite the apparent in number of offspring parents might produce per season, not all are multibrooded, suggesting trade-off. We studied ecological and behavioral factors influencing initiation second clutches great tits (Parus major), an optionally multibrooded bird species, distinguishing two types clutches:...
Abstract Ticks are parasites that feed on the blood of various vertebrate hosts, including many species bird. Birds can disperse ticks over short and long distances, therefore impacting tick population dynamics. The likelihood birds attract should depend their behaviour environment. We studied key ecological variables (breeding density, human disturbance) phenotypic traits (exploratory behaviour; body condition) proposed to predict burden in great tits ( Parus major ). Our study spanned...
