Abstract Background Socially plastic behaviours are widespread among animals and can have a significant impact on fitness. Here we investigated whether the socially responses of female Drosophila melanogaster evolve in predictable ways following long term manipulation adult sex ratio nutrient availability. Previous reports show that D. respond plastically to their immediate same-sex social environment by altering fecundity, laying fewer eggs after they mate if previously exposed other females, Fecundity is also highly sensitive female’s nutritional status, being significantly reduced when dietary protein particular scarce. On this basis, predicted an evolutionary history exposure variation would select strongly upon fecundity responses. Results We used females had been drawn from replicated lines experienced male biased, biased or equal ratios either standard low-quality nutrition. tested specific predictions elevated competition (in female-biased regimes) for increasingly presence conspecifics, these be magnified under poor resource regimes. In contrast expectations, found were strikingly robust perturbations both sexual availability did not differ across any The lack response explained insufficient strength selection. For example, held isolation prior mating, observe virgin egg according regime retention regime. Conclusion existence magnitude plasticity consistent with idea costs maintaining low, benefits high, itself hard wired.

Phenotypic plasticity is an important adaptive strategy that enables plants to respond environmental changes, particularly temperature fluctuations associated with global warming. In this study, the phenotypic of Iris pumila leaf traits in response elevated (by 1 °C) was investigated under controlled experimental conditions. particular, we functional and mechanistic traits: specific area (SLA), dry matter content (LDMC), water (SLWC), stomatal density (SD), thickness (LT), chlorophyll content. The results revealed induced trait-specific plastic responses, exhibiting greater than traits, reflecting their role short-term acclimation. SLA SD increased at higher temperatures, promoting photosynthesis gas exchange, while reductions SLWC, LDMC, LT, suggest a trade-off favor growth metabolic activity over structural investment. Notably, exhibited highest plasticity, emphasizing its crucial modulating photosynthetic efficiency thermal stress. Correlation analyses strong integration between distinct trait relationships emerging different These findings I. employs both rapid physiological adjustments longer-term strategies cope stress, facilitating maintaining ecological stability.

Abstract Human‐induced rapid environmental change (HIREC) is creating environments deviating considerably from natural habitats in which species evolved. Concurrently, climate warming pushing species’ climatic envelopes to geographic regions that offer novel ecological conditions. The persistence of likely affected by the interplay between degree novelty and phenotypic plasticity, turn may shape an organism's range‐shifting ability. Current modelling approaches forecast animal ranges are characterized a static representation relationship habitat use fitness, bias predictions under conditions imposed HIREC. We argue accounting for dynamic species‐resource relationships can increase realism range shift predictions. Our rationale builds on concepts fitting, process whereby individuals form successful biotic associations based suite traits they carry at time encountering condition, behavioural particular learning. These have revolutionized our view fitness settings, way these processes influence integrated them into model expansion as conceptual proof principle highlighting potentially substantial role learning ability shifts

Behavioural syndromes are suites of behaviours that corelate between-individuals but the same may also show within-individual correlations owing to state dependency or trade-offs. Therefore, overall phenotypic behavioural must be separated into their between- and components. We investigate how startle response duration (an index boldness) time taken reject an inert item investigation thoroughness) covary in beadlet sea anemones, Actinia equina . Anemones took longer a more complex compared simpler one, validating this measure thoroughness. then quantified using Bayesian analysis alternative frequentist analysis, which returned results. Startle responses decreased with anemone size while thoroughness across repeated observations, indicative simple learning. For each behaviour, repeatability was significant relatively low there no syndrome. Rather, two showed negative correlation most individuals. Thus, boldness unlikely under correlative selection, they instead expressed independently, line general pattern cross-contextual comparatively rare. It now appears extend broadly animal diversity.

Abstract Animal personalities are characterized by intra‐individual consistency and consistent inter‐individual variability in behaviour across time contexts. Personalities abound animals, ranging from sea anemones to insects, arachnids, birds, fish primates, yet the pathways mediating personality formation expression remain elusive. Social conditions during early postnatal period known determinants of mean behavioural trait expressions later life, but their relevance shaping trajectories is unknown. Here, we investigated consequences social isolation on adult plant‐inhabiting predatory mites Phytoseiulus persimilis . These adapted live groups. We hypothesized that transient experience is, deprivation any contact a sensitive window post‐hatching phase, has enduring adverse effects expression. Newly hatched were transiently reared or groups tested as adults for repeatability various within‐group behaviours, such movement patterns mutual interactions including sociability, defined propensity associate interact benignly with conspecifics, activity when alone. Groups composed individuals same different early‐life experiences repeatedly videotaped individual behaviours automatically analysed using AnimalTA. life had persistent traits well expression, measured intraclass correlation coefficients (indicating repeatability). On average, isolation‐reared females moved at higher speeds, meandered less, kept greater distances others fewer immediate neighbours than group‐reared females. Group‐reared highly repeatable distance, moving speed, meandering area explored, whereas only number neighbours. Activity, quantified proportion spent within groups, was females, activity, alone, isolation. Strikingly, also male mates influenced mated males boosting Overall, our study provides evidence phase critical lasting extend into adulthood, impairing should cascade upward, changing phenotypic composition diversity populations.

Glucocorticoids (GCs) have a wide spectrum of effects on animal behavior. A recently suggested effect involves determining the structure individual differences, that is how behavioral traits an covary, forming so-called syndromes. As GCs can exert their action in multiple ways, e.g., via rapid non-genomic or activation two highly homologous members steroid receptor family acting as transcription factors, it unclear GC modulation syndromes takes place. We exploited zebrafish line with frameshift mutation gene encoding (Gr), to investigate this question. found lack Gr altered average score several mutant line, reduced boldness, and increased activity sociability. Critically, pattern covariation between these was also substantially affected by loss Gr. The most evident association involved boldness gr line. This study reveals that, zebrafish, not only value traits, but are interrelated determine

Behavioural plasticity is an important mechanism allowing animals to cope with changing environments. Theory has hypothesized the existence of 'plasticity syndromes'-positive correlations in across multiple behaviours within individual-affording a generalized ability respond environmental change. However, occurrence correlated plasticities and their potential fitness consequences natural populations remain untested. Using 40-year dataset on free-ranging Magellanic penguins, we find evidence both positively negatively behavioural plasticities. Plasticity did not strongly affect lifetime reproductive success, but its effect interannual performance varied significantly by context: reduced success average oceanic conditions, increased anomalously productive conditions and, contrary expectation, buffer against unproductive conditions. Such results highlight complex patterns behaviours, individuals environments, context-dependent role that play adaptive capacity
