The debate between the extended evolutionary synthesis (EES) and the modern synthesis (MS) partly relies on different interpretations of niche construction. We dissect the umbrella term of niche construction into three separate mechanisms: niche construction (taken in a narrow sense), in which individuals make changes to the environment; niche choice, in which individuals select an environment; and niche conformance, in which individuals change their phenotypes. Each of these individual-level mechanisms affects an individual’s phenotype-environment match, its fitness, and its individualized niche, defined in terms of the environmental conditions under which an individual can survive and reproduce. Our conceptual framework distinguishes several ways in which individuals alter the selective regimes that they and other organisms experience. It also places clear emphasis on individual differences and construes niche construction and other processes as evolved mechanisms. We therefore argue that our framework helps to resolve the tensions between EES and MS.

Preen oil, the secretion of the uropygial gland, may be an important source of body odour in birds. By characterizing the chemical composition of preen oil, we can describe the olfactory phenotypes of birds and investigate whether odours could have a function in sexual signalling or other chemical communication. Here we analysed the preen oil of a wild passerine, the European Pied Flycatcher Ficedula hypoleuca, to find out whether it holds socially relevant information. We sampled both the female and male of breeding pairs during nestling rearing to test for sex differences and within‐pair similarity. We additionally sampled the females during incubation to test for changes across breeding stages and for individual repeatability of chemical profiles. Pair mates had similar chemical profiles in comparison with other breeding adults. Furthermore, we found evidence for sex differences and for changes across breeding stages. Notably, the preen oil of females was more diverse and more volatile than that of males, and the preen oil secreted by females during incubation was more volatile than that secreted during nestling rearing. However, we found no evidence for individual repeatability of chemical profiles across breeding stages in females. Our results point towards a function of preen oil in sexual signalling, although other functions should not be excluded. Our study is a first step towards understanding the role of odours in the social life of an important avian model species used in the study of mate choice and sexual selection. [ABSTRACT FROM AUTHOR]

It is now well established that birds use their sense of smell to interact with their environment. For example, birds use olfaction to locate food (Wikelski et al. 2021, Cunningham et al. 2009), for predator detection (Amo et al. 2008, 2011) or navigation (Gagliardo et al. 2013). Birds can also use olfaction in social interactions with conspecifics, for example for species or kin recognition (Hagelin et al. 2003, Caspers et al. 2017), but it is still under debate how common and important this is. If birds use odors to communicate, there should be variation among individuals (to communicate information such as sex, kinship or individual identity) and/or seasonal variation within individuals (to communicate information such as reproductive state) in their body odor. Indeed seasonal changes in preen oil have been found in almost all studied bird species (Grieves et al. 2022). In addition to the possibility that seasonal changes are used for intraspecific communication (mate choice, parent-offspring communication), there is evidence, particularly from ground-nesting birds, that seasonal changes in preen oil limits predation at the nest via olfactory crypsis (Reneerkens et al. 2005, Grieves et al. 2022). Another hypothesis for the seasonal change in preen oil composition is the prevention of bacterial infections via antimicrobial activity, especially during incubation (Martín-Vivaldi et al. 2010). In this study, we will investigate the variation in preen oil composition (a proxy of body odor in birds) in a wild passerine, the Pied Flycatcher (Ficedula hypoleuca). We sampled preen oil from adults breeding in nestboxes during incubation and nestling-rearing, and from nestlings, and we analyzed its chemical composition using gas chromatography-mass spectrometry (GC-MS). We will test whether preen oil in this species contains chemical information about sex, breeding stage, life stage, individual identity and family groups, that could be used in social interactions or may reflect a protective function (olfactory crypsis, antimicrobial activity). This study is a replication of the pilot study presented in Gilles et al. 2023 (revision under review). We aim to reproduce the findings from this study using a larger sample size. This pre-registration is not pertaining to the field work (carried out in spring 2020) or the chemical analysis (carried out in 2022), but to the statistical analysis. No data were visualized or analyzed in any way before the upload of this pre-registration.

The level of male-male competition is an important dimension of the male social niche. When males provide parental care, they potentially face a trade-off between obtaining additional fertilizations and providing care to their offspring. In this study, we will investigate how males plastically adjust their reproductive phenotype, specifically their provision of parental care, depending on the opportunity for extra-pair mating and/or level of sperm competition risk. To this aim, we will experimentally manipulate the social environment in which males are breeding. The study complements a previous, preregistered experiment focusing on male phenotypic adjustment of competitive traits in response to different levels of sperm competition risk (see Lilie, N. D., Riyahi, S., Korsten, P., & Schmoll, T., 2019, July 11. 'Male social niche conformance in zebra finches'. Retrieved from osf.io/84z5r). In the current preregistered study, we will expose males of a well-characterized model species, the socially monogamous zebra finch, to two social treatment levels: double-pair housing, inducing an opportunity for extra-pair mating and elevated sperm competition risk, versus single-pair housing with no opportunity for extra-pair mating or sperm competition risk. We will measure the male phenotypic responses to these different social treatments focusing on their contributions to parental care and their plasma levels of the hormones testosterone and corticosterone. In addition, we will quantify the effects of the social treatment and its resulting male responses on offspring growth and survival.

Individuals differ. This seemingly trivial statement has nevertheless led to paradigm shifts, as three different fields of organismal biology have seen a marked change in key concepts over the past few decades. In animal behaviour, it has increasingly been realised that behavioural differences among individuals can be stable over time and across contexts, giving rise to the concept of animal personalities. In ecology, an increasing focus is likewise on the considerable variation in the ecological niche realised by species, populations, and individuals, giving rise to the concept of niche specialisation or individual niche variation. In evolutionary biology, where individual variation has always been central, there is an increasing awareness of the complexity with which individuals interact with the environment in producing unique phenotypes. Recent theoretical and empirical work has highlighted that the fitness landscape is rather complex, with multiple fitness peaks. It depends on the individual with its genotype, in interaction with its specific environment, which local or global fitness peak is attainable. Over the past 15 years, the need for more integrated conceptual frameworks transcending disciplines has been voiced ever more strongly. Whereas initially the ecological time scale was deemed to be fundamentally different from the evolutionary one, this notion has recently been replaced by a more integrative one, where evolution can indeed happen over ecological time scales. While in each of the three fields behaviour, ecology, and evolution, the concept of individualisation has contributed to major scientific progress, sufficient cross-fertilisation is lacking. Here, we propose a new level of conceptual unification: the individualised niche. By merging the niche concept with the fitness and animal personality concepts, new explanatory power for both ecological and evolutionary processes emerges.

In species with direct sperm transfer, copulation duration is a crucial trait that may affect male and female reproductive success and that may vary with the quality of the mating partner. Furthermore, traits such as copulation duration represent the outcome of behavioral interactions between the sexes, for which it is important—but often difficult—to determine which sex is in phenotypic control. Using a double‐mating protocol, we compared copulation durations between (1) virgin and nonvirgin and (2) sibling and nonsibling mating pairs in rufous grasshoppers Gomphocerippus rufus. Nonvirgin copulations took on average approximately 30% longer than virgin copulations, whereas relatedness of mating partners was not a significant predictor of copulation duration. Longer nonvirgin copulations may represent a male adaptation to sperm competition if longer copulations allow more sperm to be transferred or function as postinsemination mate guarding. The absence of differences between pairs with different degrees of relatedness suggests no precopulatory or preinsemination inbreeding avoidance mechanism has evolved in this species, perhaps because there is no inbreeding depression in this species, or because inbreeding avoidance occurs after copulation. Controlling for the effects of male and female mating status (virgin vs. nonvirgin) and relatedness (sibling vs. nonsibling), we found significant repeatabilities (R) in copulation duration for males (R = 0.33; 95% CI: 0.09–0.55) but not for females (R = 0.09; 95% CI: 0.00–0.30). Thus, copulation durations of males more strongly represent a nontransient trait expressed in a consistent manner with different mating partners, suggesting that some aspect of the male phenotype may determine copulation duration in this species. However, overlapping confidence intervals for our sex‐specific repeatability estimates indicate that higher sampling effort is required for conclusive evidence.

Preen oil – the secretion from the uropygial gland of birds – may have diverse functions in avian reproduction: protection against eggshell bacteria, olfactory crypsis against nest predators and olfactory mate choice. To investigate such functions, we should first characterise variation in preen oil composition, but also confirm that previously described patterns are robust. Replication studies are crucial to test the reproducibility of previous findings, but are rarely undertaken in chemical ecology. Here, we conducted an almost exact replication of a previous study on the chemical composition of preen oil in a wild passerine bird, the pied flycatcher
Ficedula hypoleuca . We aimed to estimate the reproducibility of the previous results using larger sample sizes and following a pre‐registered analysis. In addition, we explored the ontogeny of preen oil composition by comparing nestling and adult preen oil. In line with previous findings, preen oil composition was similar between breeding partners and not repeatable within individual females across breeding stages. Female preen oil changed across breeding stages more clearly than in the original study (higher richness, diversity and volatility during incubation than nestling‐rearing), further refuting a role of preen oil in olfactory crypsis in this species. Unlike the original study, we found no difference in chemical profiles between sexes (nestling‐rearing), casting doubt on the proposed role of preen oil as a sex semiochemical in this species. Nestling preen oil differed from adults, was more similar to adult males than to adult females, but was not more similar to parents than to non‐parents. We found family chemical signatures, which, along with the breeding pair signature, suggests an influence of the nest environment on preen oil composition. Our study highlights the importance of replication and provides novel insights into the function and development of preen oil. [ABSTRACT FROM AUTHOR]- Published

Re-occupation of existing nesting burrows in the European bee-eater Merops apiaster has only rarely - and if so mostly anecdotically - been documented in the literature record, although such behavior would substantially save time and energy. In this study, we quantify burrow re-occupation in a German colony over a period of eleven years and identify ecological variables determining reuse probability. Of 179 recorded broods, 54% took place in a reused burrow and the overall probability that one of 75 individually recognized burrows would be reused in a given subsequent year was estimated as 26.4%. This indicates that between-year burrow reuse is a common behavior in the study colony which contrasts with findings from studies in other colonies. Furthermore, burrow re-occupation probability declined highly significantly with increasing age of the breeding wall. Statistical separation of within- and between-burrow effects of the age of the breeding wall revealed that a decline in re-occupation probability with individual burrow age was responsible for this and not a selective disappearance of burrows with high re-occupation probability over time. Limited duty cycles of individual burrows may be caused by accumulating detritus or decreasing stability with increasing burrow age. Alternatively, burrow fidelity may presuppose pair fidelity which may also explain the observed restricted burrow reuse duty cycles. A consequent next step would be to extend our within-colony approach to other colonies and compare the ecological circumstances under which bee-eaters reuse breeding burrows.

Background: Spermatozoa display impressive variation in size and form among and within animal species. In birds, comparative evidence suggests that post-copulatory sexual selection resulting from extra-pair copulations is a major driver of interspecific sperm trait variation. However little is known about the extent, determinants and dynamics of intraspecific variation in avian sperm traits. Goal: Characterize and analyze variation in sperm morphology within and among two natural populations of great tits (Parus major) — a socially monogamous passerine with frequent extra-pair matings. Methods: We studied both a German and a Norwegian population of P. major. In the German population we sampled spermatozoa during both the first clutch egg-laying and the nestling period (partly from the same individual males). In the Norwegian population we sampled spermatozoa during the pre-laying/egg-laying period. We measured the length of spermatozoa with separate measurements of sperm head, midpiece and tail length. Results: In the German population, spermatozoa were significantly shorter during the nestling period than during the egg-laying period. Individual phenotypic plasticity was responsible for the seasonal dynamics in sperm morphology. Changes in flagellum length (sum of midpiece and tail length) rather than changes in head length accounted for the change observed in total length. We found that changes in flagellum length were attributable to both midpiece and, in particular, tail shortening. Consequently the ratio, 'midpiece/total length,' increased over the breeding cycle. Controlling statistically for seasonal variation, sperm total length was significantly repeatable across sperm samples from the same males. Furthermore, spermatozoa sampled in a Norwegian population early in the season differed from those obtained from the German population during egg-laying, but not from those obtained from the German population during the nestling period. Conclusions: Individual phenotypic plasticity across the breeding season may contribute to intraspecific variation in avian sperm morphology. Our comparison across populations illustrates that seasonal variation in sperm dimensions within populations may confound between-population comparisons unless one controls for sampling date in relation to reproductive phenology.Great tit, individual phenotypic plasticity, Parus major, population divergence, repeatability, seasonality, sperm competition, sperm morphology

Spermatozoa represent the morphologically most diverse type of animal cells and show remarkable variation in size across and also within species. To understand the evolution of this diversity, it is important to reveal to what degree this variation is genetic or environmental in origin and whether this depends on species' life histories. Here we applied quantitative genetic methods to a pedigreed multigenerational data set of the collared flycatcher Ficedula albicollis, a passerine bird with high levels of extra‐pair paternity, to partition genetic and environmental sources of phenotypic variation in sperm dimensions for the first time in a natural population. Narrow‐sense heritability (h2) of total sperm length amounted to 0.44 ± 0.14 SE, whereas the corresponding figure for evolvability (estimated as coefficient of additive genetic variation, CVa) was 0.02 ± 0.003 SE. We also found an increase in total sperm length within individual males between the arrival and nestling period. This seasonal variation may reflect constraints in the production of fully elongated spermatozoa shortly after arrival at the breeding grounds. There was no evidence of an effect of male age on sperm dimensions. In many previous studies on laboratory populations of several insect, mammal and avian species, heritabilities of sperm morphology were higher, whereas evolvabilities were similar. Explanations for the differences in heritability may include variation in the environment (laboratory vs. wild), intensity of sexual selection via sperm competition (high vs. low) and genetic architecture that involves unusual linkage disequilibrium coupled with overdominance in one of the studied species.

1. Variation in larval food composition can have far-reaching effects on the adult phenotype of insects. To maximise reproductive output, it is therefore beneficial if insects are able to plastically adapt to nutritional cues in their larval diet. 2. The expression of sexual traits implicated in pre- and postcopulatory sexual selection of the lesser wax moth, Achroia grisella Fabricius, across different rearing environments of varying diet composition was investigated . 3. Moths reared on diet with relatively low amounts of carbohydrate, but more protein and fats, had lower survival rates, decreased body mass, and longer development times. Males reared on this diet produced songs with higher pulse pair rates (which are attractive to females) and transferred more sperm per copulation than males reared on the alternative diets. 4. There was no evidence for a trade-off between pre- and postcopulatory traits. Interestingly, individuals with both higher pulse pair rates and more transferred sperm came from the treatment group with higher mortality rates and generally poorer development. The present results suggest that both of these sexual characteristics are developmentally plastic, but that only moths reared on the protein-rich diet were able to benefit from this plasticity.
