Songbirds adjust their vocal production in response to increasing noise, but auditory processing of signals in noise remains understudied. Auditory processing characteristics, including auditory filter bandwidth, filter efficiency, and critical ratios (level-independent signal-to-noise ratios at threshold) likely influence auditory and behavioral responses to noise. Here, we investigated the effects of noise on auditory processing in three songbird species (black-capped chickadees, tufted titmice, and white-breasted nuthatches) that live in mixed-species flocks and rely on heterospecific communication to coordinate mobbing behaviors. We determined masked thresholds and critical ratios from 1-4 kHz using auditory evoked potentials. We predicted that nuthatches would have the lowest critical ratios given that they have narrowest filters, followed by titmice and then chickadees. We found that nuthatches had the greatest sensitivity in quiet conditions, but the highest critical ratios, suggesting their auditory sensitivity is highly susceptible to noise. Titmice had the lowest critical ratios, suggesting relatively minor impacts of noise on their auditory processing. This is not consistent with predictions based on auditory filter bandwidth, but is consistent with both recent behavioral findings and predictions made by auditory filter efficiency measures. Detrimental effects of noise were most prevalent in the 2-4 kHz range, frequencies produced in vocalizations. Our results using the critical ratio as a measure of processing in noise suggest that low levels of anthropogenic noise may influence these three species differently.","PeriodicalId":15786,"journal":{"name":"Journal of Experimental Biology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144021681","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}

To explore the functional role of the MSTN (named EcMSTN) in Exopalaemon carinicauda and to facilitate the development of new strains with enhanced growth rates, we investigated the molecular characteristics, expression patterns, and functional implications of EcMSTN. We employed CRISPR/Cas9-mediated gene editing technology to generate EcMSTN knockout (EcMSTN-KO) prawns and subsequently monitored the hatching rate, survival rate, and growth performance. The findings revealed that the hatching rate in the injected group was merely 11%, significantly lower than the 50% in the control group (p<0.05). In comparison to their wild-type (WT) siblings (1.212±0.114 cm), the EcMSTN-KO prawns (1.481±0.192) demonstrated a markedly enhancement body length (p<0.001). The expression of genes associated with myofiber composition and growth, including myosin heavy chain 2 (EcMHC2) and myosin light chain 1 (EcMLC1), exhibited a highly significant increase (p<0.001) in EcMSTN-KO prawns. Additionally, the expression of ecdysone receptor (EcEcR), a molt-related gene, was significantly elevated (p<0.001), while the expression of retinoid X receptor (EcRXR) showed no significant difference (p>0.05). The above studies indicate that EcMSTN functions as a negative regulator of muscle growth in E. carinicauda. Moreover, EcMSTN may play a potential role in molting. These results underscore the significant potential of MSTN as a genetic target for improving crustacean aquaculture, particularly through gene editing technologies aimed at enhancing growth traits.","PeriodicalId":15786,"journal":{"name":"Journal of Experimental Biology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143988140","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}

Joints can be categorized by their shape and articulation type, but such schemes might be unreliable for inferring function across the full diversity of vertebrates. We test hypothesized relationships between joint form and function by collecting marker-based ex vivo, cadaveric XROMM data on the shoulder and elbow joints of the tegu lizard (Salvator merianae) and Virginia opossum (Didelphis virginiana), which between them contain articulations historically classified as ball-and-socket, hemi-sellar, hinge and condylar joints. We measured 3D rotational and translational mobility at each joint and compared our experimental results against predictions based on articular morphology. Contrary to our predictions, the opossum ball-and-socket shoulder joint was less mobile- it had a smaller 3D range of motion envelope- than the tegu hemi-sellar shoulder joint and even the tegu condylar elbow joint, challenging the notion that ball-and-socket shoulder provides an inherent mobility advantage. However, the ball-and-socket opossum shoulder also had a less complex mobility envelope, with fewer interactions between degrees of freedom, allowing it to transition between poses more easily. Matching osteological predictions, the hinge elbow of the opossum was the least mobile. All joints exhibited coupling between rotational and translational degrees of freedom, and we further emphasize the need to incorporate translational motion and soft tissue constraints for accurately modelling joint mobility. Our findings underscore the complexity of form-function relationships in vertebrate skeletal joints, and demonstrate that joint morphology alone, in the absence of soft tissues, does not provide a complete picture of joint mobility.","PeriodicalId":15786,"journal":{"name":"Journal of Experimental Biology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143780184","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}

Beyond functions of the eyes, recent investigations have documented the importance of extraocular photoreception in behavior. Octopus arms have been shown to respond behaviorally to local light exposure with negative phototaxis. Moreover, light-activated chromatophore expansion (LACE) in octopus arms indicates that skin-based photoreception may contribute to light detection. In this study, we used electrophysiological recordings to investigate the neural activity of the arm's axial nerve cord in response to light on the arm. We tested the hypothesis that light stimulates the activity of neurons in the arm's axial nerve cord. We also aimed to determine sensitivity to different wavelengths of light. The results showed that the axial nerve cord is strongly responsive to light stimulation of the arm and that the response travels along the length of the axial nerve cord. Blue light generated the strongest neural activity while red and green light also induced responses. Light-induced neural activity was mediated through the aboral arm skin and by the oral-side skin and suckers. These findings reveal the role of the skin in the sensory abilities of octopuses and provide insights into the neural mechanisms underlying their response to light. Our study underscores the importance of extraocular photoreception in future investigations of cephalopod sensory and behavioral biology.","PeriodicalId":15786,"journal":{"name":"Journal of Experimental Biology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11993263/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143605099","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}

However, performance is a complex trait, and organisms must balance competing demands of multiple underlying factors every time they undertake an activity. For example, the morphology that increases bite force (i.e. increased head size) - improving fighting ability - should constrain sprinting performance by adding mass to the body. Consequently, trade-offs between fighting and escape performance might be sex specific where sexual dimorphism is present, or pronounced in animals with extreme breeding strategies. Northern quolls (Dasyurus hallucatus) are a sexually dimorphic marsupial, with sex-specific life history strategies; males die after a single synchronous breeding season, while females can live and breed for 2-3 years. We investigated the effects of sex and life history on whole-animal performance and assessed whether sprint speed and bite force trade off among or within individual male and female quolls. We used a repeated measures dataset spanning 3 years. We identified significant sex differences in morphology and performance, notably after breeding, where male sprint speed decreases but female bite force increases. Both body size and body condition were strong predictors of performance. However, we found no trade-off between sprint speed and bite force, suggesting that ecologically relevant tasks for survival and reproduction - fighting capacity and escape ability - may evolve independently in both male and female northern quolls. Finally, we assessed the repeatability of morphological and performance traits and demonstrated the importance of study design when quantifying variance in animal performance, especially for animals with complex life histories.","PeriodicalId":15786,"journal":{"name":"Journal of Experimental Biology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12045626/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143605111","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 is critical when genetic variants have pleiotropic effects, as determining how each phenotype impacted by a gene contributes to fitness is essential to understand how and why traits have evolved. Here, we characterized the effects of mutations in the oca2 gene, which underlie albinism and reductions of sleep in the blind Mexican cavefish Astyanax mexicanus, on larval prey capture. We found that when surface A. mexicanus with engineered mutations in oca2 are hunting, they use cave-like, wide-angle strikes to capture prey. However, unlike cavefish or surface fish in the dark, which utilize the lateral line when hunting, oca2 mutant (oca2Δ2bp/Δ2bp) surface fish can use vision when striking at prey from wide angles. We found that when raised under lighted conditions, pigmented surface fish outcompete albino oca2Δ2bp/Δ2bp surface fish when hunting in lighted conditions. In contrast, when surface fish are reared in darkness, oca2Δ2bp/Δ2bp surface fish outcompete their wild type siblings in the dark. This raises the possibility that albinism is detrimental to larval feeding in a surface-like lighted environment, but may confer an advantage to fish in cave-like, dark environments. Together, these results demonstrate that oca2 plays a role in larval feeding behavior in A. mexicanus, and expand our understanding of the pleiotropic phenotypic consequences of oca2 in cavefish evolution.","PeriodicalId":15786,"journal":{"name":"Journal of Experimental Biology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12045627/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143649055","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}

Here, we identify the mechanical behavior that provides marine turtles, species characterized with fusiform shells, with biomechanical strength and resilience. The multi-layered carapacial bone structure seemingly serves a protective role for the muscles, nerves and viscera it houses. What are the shell's material properties that provide protection? Most previous work has focused on non-marine turtles, which differ in natural history and shell morphology from marine species. We measured carapacial mechanical behavior of green turtle (Chelonia mydas), loggerhead (Caretta caretta) and Kemp's ridleys (Lepidochelys kempii) across a range of body sizes in juveniles, subadults and adults. Carapace samples were tested using quasi-static compression to quantify stiffness (Young's modulus), yield strength and toughness. The mechanical characteristics of marine turtle shells are grossly akin to those of other turtles and driven by the bone's sandwich structure. Yet, the material properties indicate that marine turtle shells are less stiff and strong than those of their freshwater and terrestrial counterparts. We hypothesize that increased flexibility of the shell may reflect tradeoffs for life that include experiencing pressure from diving somewhat deeply in marine environments. Shell material properties also differ among species and ontogenetically. Green turtles have the stiffest, strongest and toughest shells while loggerhead carapaces are the most compliant. Stiffness and yield strength show positive relationships with body size which are most pronounced in green turtles and Kemp's ridleys. Phylogenetic histories and ecological differences likely drive this interspecific variation.","PeriodicalId":15786,"journal":{"name":"Journal of Experimental Biology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143624714","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}

Yet, experimental measures of in vivo muscle energetics are challenging to obtain, so physiologically based muscle models are often used to estimate energy use. These predictions of individual muscle energy expenditure are not often compared with indirect whole-body measures of energetic cost. Here, we examined and illustrated the capability of physiologically based muscle models to predict in vivo measures of energy use, which rely on fundamental relationships between muscle mechanical state and energy consumption. To improve model predictions and ensure a physiological basis for model parameters, we refined our model to include data from isolated muscle experiments and account for inefficiencies in ATP recovery processes. Simulations were performed to capture three different experimental protocols, which involved varying contraction frequency, duty cycle and muscle fascicle length. Our results demonstrated the ability of the model to capture the dependence of energetic cost on mechanical state across contractile conditions, but tended to underpredict the magnitude of energetic cost. Our analysis revealed that the model was most sensitive to the force-velocity parameters and the data informing the energetic parameters when predicting in vivo energetic rates. This work highlights that it is the mechanics of skeletal muscle contraction that govern muscle energy use, although the precise physiological parameters for human muscle likely require detailed investigation.","PeriodicalId":15786,"journal":{"name":"Journal of Experimental Biology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11993265/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143441164","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}

Identifying the underlying factors driving interspecific variation in BMR remains a major question in the field of energetics. While body size (M) and taxonomic affiliation are the intrinsic factors that account for most of the interspecific variation in BMR, haploid genome size (C-value) is hypothesized to directly influence cell size and, indirectly, the specific metabolic rate. Climatic variables, mostly ambient temperature, have also been proposed as predictors of mass-independent BMR for endotherms. Therefore, in this study, we aimed to investigate the relative importance of intrinsic (C-value: CV) and extrinsic (climatic variables) factors as predictors of BMR in 67 rodent species in a phylogenetic context. The best ordinary least square (OLS) and phylogenetic generalized least squares (PGLS) models explaining interspecific variation in BMR included the variables logM, logCV, maximum temperature of the warmest month (Tmax), minimum temperature of the coldest month (Tmin) and net primary productivity (NPP). logM was the main determinant of logBMR variation in the rodents analyzed. Part of the remaining variation was attributed to a negative effect of genome size, explaining 14% of the BMR variance when Tmin was included in the model. As expected, one or two climatic variables were involved in explaining the remaining BMR variation (Tmin, Tmax and NPP). Our study highlights the importance of a denser sampling within vertebrate clades and the use of a phylogenetic context to elucidate the factors that contribute to explain BMR variation.","PeriodicalId":15786,"journal":{"name":"Journal of Experimental Biology","volume":" ","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143501951","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}
