The teleost oral jaws are a complex mechanical system, and a multifunction tradeoff is thought to exist between the opposing functions of suction-based and biting-based feeding. We experimentally measured suction- and biting-based feeding performance across 10 heroine cichlid species spanning a range of ecomorphological diversity to test for the presence of a suction-biting tradeoff. We found an inverse relationship between suction-based and biting-based feeding performance across species, as well as significant relationships between performance and morphological features of the oral jaws, where larger oral-jaw gape and greater protrusion were associated with improved suction-feeding and decreased benthic-feeding performance. We observed a fivefold range among species in biting rates during benthic-feeding trials, with a twofold range observed among benthic-feeding specialists, and propose that diversity in the properties of attached prey has generated diversity among biting-based specialists reliant on high-force bites versus those reliant on high biting rates.","PeriodicalId":15786,"journal":{"name":"Journal of Experimental Biology","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13615685/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148591883","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}

Seasonal changes in thyroid hormone levels in bottlenose dolphins suggest potential seasonal effects on resting metabolic rate (RMR). To explore this potential, the RMR of nine adult and four adolescent bottlenose dolphins were measured monthly for 13 months using open-flow respirometry. Oxygen consumption was measured while dolphins were post-absorptive and during the morning to avoid diurnal hormone fluctuations. Blood samples were collected from six of the adult dolphins immediately following oxygen consumption measurements and assessed for levels of total and free T3 (fT3), reverse T3 (rT3), total and free T4 (tT4 and fT4, respectively), and cortisol. Resting metabolic rate varied seasonally in mature dolphins; RMRs were lower in the spring and higher in the summer and fall. Suppression of RMR in the spring was followed by a progressive increase in RMR through the summer and fall. The mean mass-specific RMR of adolescent dolphins (5.49 ml O2 min-1 kg-1) was higher than that of adult dolphins (4.38 O2 min-1 kg-1), and the RMR of adults did not vary between sexes. The RMR of adult dolphins was significantly related to serum concentrations of tT3 and fT3, whereas rT3, fT3 and tT3 were all significantly related to photoperiod. The entrainment of seasonal changes in dolphin RMR is probably driven by photoperiod, although the signaling mechanism mediated by melatonin is likely altered in this species because it lacks a defined pineal gland.","PeriodicalId":15786,"journal":{"name":"Journal of Experimental Biology","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148630777","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}

Despite its importance, significant gaps remain in our understanding of the mechanisms underlying feather water repellency. This property arises primarily from feather microstructure. Feather morphology varies widely among bird species. However, the functional consequences of this variation for feather wettability remain poorly understood. Advances in computer-aided 3D modeling enable us to investigate such structure-function relationships with unprecedented precision. In this study, we created 3D feather models from micro-computed tomography scans of a seaside sparrow feather and systematically altered its morphology, specifically barbule density, to observe how feathers interact with water droplets using computational fluid dynamics simulations. We quantified the spatio-temporal distribution of droplet behavior, measured spreading radii during interactions, and assessed final contact angles for feathers with varying barbule densities. We validated our simulation results with barbule-density estimates and static contact-angle measurements on contour feathers from four New World sparrow species, including the seaside sparrow, spanning a gradient in water exposure. Together, the computational and experimental results demonstrate that higher barbule density reduces water repellency. Collectively, these findings highlight how feather microstructure directly governs feather wettability.","PeriodicalId":15786,"journal":{"name":"Journal of Experimental Biology","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148684806","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}

Core amongst these genes are the vha genes, which encode subunits of the large vacuolar-type ATPase (V-ATPase) proton pump complex. However, many of the non-vha components of the epitheliome remain broadly uncharacterised. Here, we explored the role of RNAseK, a gene identified during unbiased epithelial screens in Drosophila whose function within insects is not yet known, though evidence from mammalian systems suggests a role in supporting proton pump activity. We demonstrate computationally that RNAseK is strongly conserved across evolutionary history, and that expression is regulated by the highly epithelium-specific dCLEAR motif. Seeking to understand why epithelial expression is so emphasised, we assayed the effects of RNAseK knockdown in different epithelia throughout the fly. Across hindgut, midgut and Malpighian tubules, we note profound defects in gross tissue morphology, transport activity and fly survival. Mechanistically, RNAseK co-localises apically with the V-ATPase subunit Vha55, and RNAseK knockdown phenotypes overlap with those caused by V-ATPase perturbation. These findings are consistent with a role for RNAseK in acidification-dependent epithelial transport and membrane homeostasis, although direct effects on V-ATPase biochemical activity or on other epithelial transport and junctional pathways remain to be tested.","PeriodicalId":15786,"journal":{"name":"Journal of Experimental Biology","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13615687/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148562082","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}

In hoverflies, for example, visual looming stimuli may be generated if the insect is about to collide with a stationary object in the surround, by an approaching predator, or by conspecifics during territorial interactions. Supporting these behavioural responses is a diverse range of looming-sensitive descending neurons that project information from the optic lobes and central brain to the motor control centres in the thoracic ganglia. We show here that these neurons are predominantly sensitive to looming stimuli located in the ventral visual field. To investigate if this is matched by behaviour, we recorded how tethered hoverflies responded to looming stimuli presented dorsally or ventrally on a visual monitor, at four different speeds (l⧸|v| of 10-667 ms), covering a naturalistic range. We found that ventral stimuli, especially at intermediate speeds (l⧸|v|=50 or 200 ms), triggered much stronger behavioural responses than dorsally displayed stimuli. The behavioural data thus not only match the receptive fields of the neurons likely to support the behaviour but also highlight that behavioural output is not entirely reflexive but is strongly modulated by stimulus speed and elevation.","PeriodicalId":15786,"journal":{"name":"Journal of Experimental Biology","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13615673/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148761560","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}

For example, ants, bees and rats have long been known to use path integration, a mechanism to integrate distance and direction travelled, to find their way back to their nest. However, path integration is imperfect, and errors accumulate over time as animals forage. There are several ways to counteract this uncertainty, for example by utilizing local olfactory or visual landmarks along a familiar route to infer an individual's position relative to its nest, i.e. its homing vector. Local landmarks are thought to be effective if they are constant, granting a strong association with the discrete location at which they are located. Here, we showed that ants can utilize something much sparser and more distributed than an individual constant landmark to inform its homing vector. Our data suggest that Tunisian desert ants integrate intraspecific contact, or social cues, to augment navigation. Although exposing homing ants that arrive at their expected nest position to colony members has no effect on their subsequent nest-search behaviour, contact with foreign conspecifics at a position where the nest is expected diminishes path integration certainty, thereby expanding the nest search pattern. Furthermore, we showed that ants form associations between intraspecific conflict and discrete locations to create so-called local vectors, within which the homing path to the nest can be stored. Apparently, ants remember aggressive interactions and take them into account when navigating.","PeriodicalId":15786,"journal":{"name":"Journal of Experimental Biology","volume":"229 17","pages":""},"PeriodicalIF":3.0,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13615672/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148900555","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}

In stark contrast, nociceptive sensory stimuli trigger the larvae to roll across the substrate by corkscrewing around the long body axis. Here, we have determined the detailed timing of muscle activation that generates the body rotation across abdominal segments. To do so, we developed a high-speed confocal time-lapse imaging preparation that allowed us to trigger rolling with nociceptor optogenetics while simultaneously imaging a genetically encoded calcium sensor expressed in the muscles. Of the 30 muscles present in each larval abdominal hemisegment, we found that only 11 muscles are consistently and specifically activated across segments during rolling. Eight additional muscles are more sparsely activated. Importantly, the sequential pattern of muscle recruitment during rolling is completely distinct from that of forward or reverse crawling. A roll involves a wave of muscle activation that propagates around the larval circumference (in the transverse plane of each segment) and involves four co-active muscle groups. A pattern of activation progresses from co-active ventral muscle groups to dorsal groups and then spreads across the midline to the contralateral dorsal muscle groups, then progresses back to the ventral groups. The direction of a roll is determined by the clockwise or counterclockwise order of muscle group activation around the transverse plane. Finally, an analysis of the connectivity of inputs to larval motor neurons revealed a ring-like network architecture that could support the sequence of activation of the rolling motor pattern.","PeriodicalId":15786,"journal":{"name":"Journal of Experimental Biology","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13615696/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148865172","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}

Eradication campaigns, such as \"See It, Squish It,\" rely on mechanical elimination. However, lanternflies often escape by executing hindlimb-driven leaps. Although escape rates remain unquantified, the physical nature of these eradication attempts likely results in individuals surviving with damaged/missing limbs. Lanternflies do not exhibit limb autotomy, and it remains unclear how well they tolerate injury. To evaluate the effects of limb loss on locomotor performance, we amputated a single fore-, mid-, or hindlimb in lanternfly nymphs and measured three ecologically relevant metrics: jumping and climbing velocity and pull-strength. We also tracked recovery over several days post-amputation for jumping and climbing trials. Jumping velocity and pull-strength were unaffected by limb removal. In contrast, climbing velocity declined significantly across all groups, with the greatest reductions observed following forelimb and hindlimb removal. This decrease in climbing velocity was associated with changes in both stride length and stride frequency. However, because climbing velocity also declined in the control group, it remains unclear whether limb amputation alone-or the intervention itself-was responsible for these effects. No evidence of performance recovery was observed over time. These findings demonstrate the fault-tolerant nature of the lanternfly locomotor system, likely supported by mechanical redundancy and decentralized neuromuscular control. The ability to maintain essential behaviors following limb loss may represent a complementary evolutionary strategy to autotomy-centered on resilience rather than pre-programed limb sacrifice. This performance robustness likely contributes to the lanternfly's invasive success.","PeriodicalId":15786,"journal":{"name":"Journal of Experimental Biology","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2026-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148793961","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}
