Variation in oxidative status, but not structural and physiological development, associated with changing ontogenetic environments
<p><span>Despite the potential for temporally-dependent relationships between trait values and fitness (e.g., as juveniles approach life-stage transitions such as fledging), how developmental stage affects canalization (a measure of robustness to environmental variation) of morphological and physiological traits is rarely considered. To test the sensitivity of morphological and physiological traits to environmental variation in two developmental stages, we manipulated brood size at hatch in European starlings (<em>Sturnus vulgaris</em>) and cross-fostered chicks between enlarged and reduced broods approaching fledging.</span><span> We measured body size (mass, tarsus, wing length) and physiological state (aerobic capacity, oxidative status) at asymptotic mass on day 15, then cross-fostered chicks between 'high' and 'low' quality environments and assessed the same traits again on day 20, after five days of pre-fledging mass recession. Chicks in reduced broods were heavier at asymptotic mass and had lower reactive oxygen metabolites than enlarged broods, while structural size, aerobic capacity, and antioxidant capacity were unaffected by experimental brood size. The observed canalization of structural and physiological traits during early development was maintained after cross-fostering, during late development. However, in contrast to early development, antioxidant capacity approaching fledging appeared sensitive to environmental conditions, as trajectories varied by cross-fostering treatment. Elevated reactive oxygen metabolites observed after early development in enlarged brood chicks were maintained after cross-fostering, suggesting canalized development in low-quality environments could produce oxidative costs that carry over between life-stages, even when conditions improve. These data reveal trait-specific relationships between environmental conditions and development and highlight how natal environment effects may vary by developmental stage.</span></p>

Development and evaluation of a test setup to investigate distance differences in immersive virtual environments
<p>Nowadays, with recent advances in virtual reality technology, it is easily possible to integrate real objects into<br> virtual environments by creating an exact virtual replication and enabling interaction with them by mapping the obtained tracking<br> data of the real to the virtual objects. The primary goal of our study is to develop a system to investigate distance differences for<br> near-field interaction in immersive virtual environments. In this context, the term distance difference refers to the shift between<br> a real object and the respective replication of the real object in the virtual environment of the same size. This could occur<br> for a number of reasons e.g. due to errors in motion tracking or mistakes in designing the virtual environment. Our virtual<br> environment is developed using the Unity3D game engine, while the immersive contents were displayed on an HTC Vive Pro headmounted display. The virtual room shown to the user includes a replication of the real testing lab environment, while one of<br> the two real objects is tracked and mirrored to the virtual world using an HTC Vive Tracker. Both objects are present<br> in the real as well as in the virtual world. To find perceivable distance differences in the near-field, the actual task in the<br> subjective test was to pick up one object and place it into another object. The position of the static object in the virtual<br> world is shifted by values between 0 and 4 cm, while the position of the real object is kept constant. The system is evaluated by<br> conducting a subjective proof-of-concept test with 18 test subjects. The distance difference is evaluated by the subjects through<br> estimating perceived confusion on a modified 5-point absolute category rating scale. The study provides quantitative insights<br> into allowable real-world vs. virtual-world mismatch boundaries for near-field interactions, with a threshold value of around 1 cm.</p>
Data from: Brain plasticity over the metamorphic boundary: carry-over effect of larval environment on froglet brain development
Brain development shows high plasticity in response to environmental heterogeneity. However, it is unknown how environmental variation during development may affect brain architecture across life history switch points in species with complex life cycles. Previously, we showed that predation and competition affect brain development in common frog (Rana temporaria) tadpoles. Here, we studied if larval environment had carry-over effects in brains of metamorphs. Tadpoles grown at high density had large optic tecta at metamorphosis, while tadpoles grown under predation risk had small diencephala. We found that larval density had a carry-over effect on froglet optic tectum size, while the effect of larval predation risk had vanished by metamorphosis. We discuss the possibility that the observed changes may be adaptive, reflecting the needs of an organism in given environmental and developmental contexts.
Data from: Genetic variation in social environment construction influences the development of aggressive behavior in Drosophila melanogaster
Individuals are not merely subject to their social environments; they choose and create them, through a process called social environment (or social niche) construction. When genotypes differ in social environment-constructing behaviors, different genotypes are expected to experience different social environments. As social experience often affects behavioral development, quantitative genetics and psychology theories predict that genetic variation in social environment construction should have an important role in determining phenotypic variation; however, this hypothesis has not been tested directly. I identify multiple mechanisms of social environment construction that differ among natural genotypes of Drosophila melanogaster and investigate their consequences for the development of aggressive behavior. Male genotypes differed in the group sizes that they preferred and in their aggressive behavior; both of these behaviors influenced social experience, demonstrating that these behaviors function as social environment-constructing traits. Further, the effects of social experience—as determined in part by social environment construction—carried over to affect focal male aggression at a later time and with a new opponent. These results provide manipulative experimental support for longstanding hypotheses in psychology, that genetic variation in social environment construction has a causal role in behavioral development. More broadly, these results imply that studies of the genetic basis of complex traits should be expanded to include mechanisms by which genetic variation shapes the environments that individuals experience.
Data from: Effects of perceived predation risk and social environment on the development of three-spined stickleback (Gasterosteus aculeatus) morphology
Phenotypically plastic changes in response to variation in perceived predation risk are widespread, but little is known about if and how social environment modulates induced responses to predation risk. We investigated the influence of perceived predation risk (i.e. chemical cues from a predator) and social environment (i.e. one, two or 20 individuals reared together) on three-spined stickleback (Gasterosteus aculeatus) morphology in a factorial common garden experiment. We found that exposure to chemical cues from potential predators did not influence growth or body condition or induce more robust morphological defences (i.e. lateral plate numbers and dorsal spine lengths). However, sticklebacks exposed to predator cues developed longer caudal peduncles and larger eyes as compared with fish from the control treatment. As these responses may improve sticklebacks' ability to avoid piscine predation, they might be adaptive. Social environment/density also influenced expression of some traits, but these effects were independent of predation-risk treatment effects. In general, these results suggest that apart from the classic morphological defence structures, which appear mostly constitutive, three-spined sticklebacks are capable of expressing potentially adaptive morphological responses to chemical cues from potential predators.

Data from: Female developmental environment delays development of male honeybee (Apis mellifera)
<p><b><span>Background</span></b></p> <p>Nutrition and cell size play an important role in the determination of caste differentiation in queen and worker of honeybees (<i><span>Apis mellifera</span></i>), whereas the haploid genome dominates the differentiation of drones. However, the effects of female developmental environment on the development of males remain unclear. In this study, young drone larvae were transferred into worker cells (WCs) or remained in drone cells (DCs) to rear drones. The drone larvae were also grafted into queen cells (QCs) for 48 hrs and then transplanted into drone cells until emerging. Morphological indexes and reproductive organs of these three types of newly emerged drones were measured. Newly emerged drones and 3-day drone larvae from WCs, DCs and QCs were sequenced by RNA sequencing (RNA-Seq).</p> <p><b><span>Result</span></b><b><span>s</span></b></p> <p>The amount of food remaining in cells of the QC and WC groups was significantly different to that in the DC group at the early larval stage. Morphological results showed that newly emerged DC drones had bigger body sizes and more well-developed reproductive tissues than WC and QC drones, whereas the reproductive tissues of QC drones were relatively larger than those of WC drones. Additionally, gene expression results showed a clear difference among three groups. At the larval stage, there were 889, 1761 and 1927 significantly differentially expressed genes (DEGs) in WC/DC, QC/DC and WC/QC comparisons, respectively. The number of DEGs decreased in adult drones of these three comparisons [678 (WC/DC), 338 (QC/DC) and 518 (WC/QC)]. A high number of DEGs were involved in sex differentiation, growth, olfaction, vision, mammalian target of rapamycin (mTOR), Wnt signaling pathways, and other processes. </p> <p><b><span>Conclusion</span></b></p> <p>This study demonstrated that the developmental environment of honeybee females can delay male development, which serves as a model for understanding the regulation of sex differentiation and male development in social insects by environmental factors.</p>
