They forage not only in open terrain but also in cluttered environments where obstacles force them to deviate from direct paths. This study investigates the underexplored aspect of how bees become experienced foragers and optimize flight behaviour in cluttered terrains. We recorded flight trajectories of novice bees with no prior experience in navigating cluttered laboratory environments and monitored their behavioural performance as they gained experience on subsequent foraging trips through numerous obstacles. By controlling for experience levels, we analysed how flight characteristics evolve with increasing expertise. Successful navigation in cluttered terrain requires avoiding collisions with obstacles. This is only possible if these can be detected through visual features such as the retinal displacement of contrast edges. Obstacles which are harder to detect and to avoid by the bees may affect their flight performance. By introducing transparent objects into our dense environment, we challenged collision avoidance and learning mechanisms, analysing the impact on flight optimization under different environmental conditions. Our findings reveal that experienced bees fly similar paths through clutter and quickly adapt their flights regardless of their training environment. However, the specific paths followed are influenced by environmental conditions. Transparent objects primarily affect naive bees' flight patterns while having minimal impact on flight optimization, suggesting that the efficient flights of experienced bees result not solely from reflexive collision avoidance but from learning and previous experience in cluttered environments.","PeriodicalId":15786,"journal":{"name":"Journal of Experimental Biology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144528162","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Naked mole-rats (NMRs) are hypoxia-tolerant mammals and drastically reduce their metabolic rate while maintaining systemic pH homeostasis during acute hypoxia. Whether or not NMRs employ anaerobic metabolism in hypoxia is currently debated. Given the robust systemic hypoxic hypometabolism of this species we hypothesized that anaerobic metabolism is recruited on a tissue-specific basis that varies between developmental stages and colony caste position. To test this, we treated subordinate juvenile and adult, and breeding (queen) NMRs in normoxia (21% O2) or hypoxia (3% O2) for 1 h, and then measured blood lactate, glycolytic enzyme activity, and the expression of genes that encode for enzymes involved in glycogen and glucose metabolism, and lactate transport. We found that (1) blood lactate levels increase similarly during hypoxia across developmental stages and castes; but that (2) glycolytic activity increased or remained stable in subordinates and juveniles but was unchanged or reduced in queens; (3) MCT4 gene expression decreased markedly in subordinate and juvenile brain and increased in muscle and kidney, but was unchanged in queens; and (4) the expression of genes associated with glycogenolysis and gluconeogenesis varied across tissues in subordinates/juveniles with some markers being down or upregulated or unchanged, but were always unchanged or downregulated queens. Taken together, our results suggest that hypoxia upregulates glycolysis and glycogen mobilization in subordinates and juveniles, but not in queens.","PeriodicalId":15786,"journal":{"name":"Journal of Experimental Biology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144528164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the mechanistic basis of repeatable variation in behavior is less understood. Metabolic rate is a likely candidate to drive repeatability in behavior because energy metabolism can limit behavioral expression. There are competing hypotheses for the relationship (or lack thereof) between levels of maintenance metabolism such as resting metabolic rate (RMR) and the expression of behaviors. On the one hand, RMR may show a negative relationship with behavior if higher RMR limits energy that can be allocated to other processes. On the other hand, RMR may positively correlate with behavior if high RMR leads to greater energy production ability. To test these hypotheses, we examined the relationship between RMR and repeatable, highly energetically costly sexual signals in male Cope's grey treefrogs (Hyla chrysoscelis). We recorded individual male acoustic advertisement calls in the field and measured their RMR the following day. We made repeated measurements of RMR across multiple captures of the same individuals to assess the repeatability of metabolic rates, and whether consistency in RMR decreases over time. There was no evidence that RMR affected call characteristics in H. chrysoscelis. Nevertheless, RMR was significantly repeatable. We found that RMR decreased across the breeding season, which reduced the consistency in RMR measurements of the same individual over time. We conclude that calling in H. chrysoscelis does not provide information to mates or rivals on male RMR, although other aspects of metabolism may still drive individual variation in calling.","PeriodicalId":15786,"journal":{"name":"Journal of Experimental Biology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144484660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These signals exhibited amplitudes several dozen times greater than ventilatory signals, with durations approximately half as long. Spike-like pulses were not related to any detectable movements but were tightly linked to specific behavioral contexts. Most were generated upon physical contact with another lamprey or a substrate, with their source consistently located near the point of contact rather than at a fixed position within the body. Signals produced by immobile individuals in response to external stimuli differed significantly from those generated by moving individuals upon contact with a substrate. Our estimates suggest that these signals have sufficient amplitude to actively probe the surroundings, at least within several centimeters of the body.","PeriodicalId":15786,"journal":{"name":"Journal of Experimental Biology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144484658","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although hypoxia decreases physiological performance in coral and sea anemone (phylum Cnidaria) larvae, the underlying cellular mechanisms remain unexplored. Here, larvae of the reef-building corals Galaxea fascicularis and Porites astreoides and the estuarine sea anemone Nematostella vectensis were exposed to normoxia or a simulated hypoxic event (6 h at <2 mg dissolved O2 l-1), and their metabolomic response was quantified at the end of the exposure period using targeted liquid chromatography-mass spectrometry. Baseline metabolite profiles (81 amino acids, acylcarnitines, organic acids and nucleotides) were broadly divergent between the three species, with the corals displaying a reliance on nitrogen cycling through amino acid metabolism, whereas N. vectensis relied on nucleotide metabolism. By contrast, several changes in metabolite abundances under hypoxia were shared (e.g. increases in lactate) and suggest the upregulation of glycolysis, lactic acid fermentation and fatty acid β-oxidation as conserved mechanisms for energy production under hypoxia. Changes in these pathways were correlated with adverse physiological outcomes, including conserved declines in swimming behavior and growth. Importantly, life history traits affecting metabolism influenced hypoxia responses. For example, P. astreoides larvae, which possess algal endosymbionts, displayed the least severe metabolic response to hypoxia among these species, possibly owing to symbiont resources. Overall, these findings demonstrate that hypoxia disrupts metabolic performance in coral and sea anemone larvae through conserved and divergent pathways, emphasizing the need to limit drivers of ocean deoxygenation.","PeriodicalId":15786,"journal":{"name":"Journal of Experimental Biology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144199331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such adjustments can be observed, for example, in variations of heart and respiratory rates triggered by different disturbances. In invertebrates, evidence of the existence of an autonomic nervous system structure has not been found. Even so, these animals show physiological responses - changes in cardiorespiratory activity (autonomic-like responses) - that maintain internal stability. In crustaceans, studies have found changes in both behavioural response and heart rate during memory processes. In the crayfish Procambarus clarkii, recognition memory has been behaviourally described when triads of these invertebrates interact under laboratory conditions and establish a hierarchical order (a dominant animal and two submissives). The main purpose of this work was to characterize the cardiorespiratory autonomic-like responses of P. clarkii during a 5-day recognition memory protocol. Our findings indicate significant differences in cardiorespiratory activity between day 1 (start of the memory protocol) and day 5 (when recognition memory is consolidated). Notably, there are differences based on hierarchy status, suggesting that the physiological response to recognition differs between dominant and submissive animals. This indicates that the retrieval of long-term recognition memory may lead to changes in autonomic-like responses.","PeriodicalId":15786,"journal":{"name":"Journal of Experimental Biology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12211588/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144248225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This case study adds to many examples showing that applications, which themselves often take decades of development, often stem from centuries of observation and experimentation that are completely divorced from any applied research.

Such linearity is not seen for walking. We investigated whether total muscle power (Ptot), i.e. power required for the inverted pendulum motion in walking plus power against net external resistance, demonstrated such a single relationship between Ptot and MR, independent of walking conditions. We studied walking under conditions in which considerable net external work against the environment was done (walking uphill and when resistive forces are imposed) as well as on the level, i.e. without net external work done. Fifteen adults walked freely on a large treadmill at 27 combinations of three speeds (3, 4.5 and 6 kmh-1), three inclines (0%, 3% and 6%) and three resistive forces (0.1×9.81, 2.5×9.81 and 5×9.81 N). Kinematics were recorded by motion capturing. MR was estimated from gas exchange recordings. Required Ptot generated by skeletal muscle was estimated as the power associated with step-to-step transitions (Psst) in addition to net external power (Pext), with Ptot=Pext+Psst. The Pext-MR relationship was not entirely unique (R2=0.883) and was strongly affected by speed (P=0.004). The Ptot-MR relationship was stronger (R2=0.972) and the influence of walking speed was almost cancelled out. The Ptot-MR relationship resembles that found for cycling. On that basis, we conclude that Ptot seems to incorporate the major amount of work done during walking.","PeriodicalId":15786,"journal":{"name":"Journal of Experimental Biology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12211589/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144101938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This exchange is well documented at normal speeds but could break down at very slow speeds. We examined energy transduction through the phase shift between potential and kinetic energy in human walking at a wide range of speeds (0.1-2.0 m s-1), specifically capturing very slow speeds (<0.6 m s-1). We measured phase shift with two different methods. One method used two classical phase shifts of α and β from ( Cavagna and Legramandi, 2020). The second method utilized cross-correlation across each stride. We calculated phase shift from a human gait study and from two simple inverted pendulum-type walking models ( Srinivasan and Ruina, 2006; Rebula and Kuo, 2015). Participants walked at 13 prescribed speeds between 0.1 and 2.0 m s-1 on a split belt instrumented treadmill. We found that phase shifts increased as speed decreased. However, at speeds slower than 0.3 m s-1, the phase shifts approached zero. The simple walking models were unable to demonstrate phase shift behaviour at any speed. Our study demonstrates that as speed slows, humans walk less similarly to the inverted pendulum models, and more complex models may be required to characterize walking at very slow speeds.","PeriodicalId":15786,"journal":{"name":"Journal of Experimental Biology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144208702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
