The consumption of coral tissue, mucus, and skeleton is a rare feeding niche despite the abundance of coral on reefs, which raises questions about the evolutionary consequences of this dietary specialization. In this study, we used phylogenetic comparative methods, micro-CT scanning, and scanning electron microscopy to explore the evolutionary history of corallivory across reef fishes and compare feeding morphology across species within a major clade of corallivorous species (Chaetodontidae) that vary in their coral consumption. We show that obligate corallivory has evolved independently at least 17 times but is an evolutionary \"dead end\" for most reef fish species. Early origination of facultative corallivory may have contributed to the success of butterflyfishes, the predominant clade of coral-feeding fishes, as they diversified in competitive reef environments. Obligate and facultative butterflyfish species differ primarily in dental morphology while overall cranial traits are largely similar between groups. Coral feeding requires continuous foraging with narrow energetic margins, and climate-driven disturbances occur markedly faster than evolutionary transitions away from corallivory.

Dorsoventral oscillation of the flexible pectoral fins is driven by muscles at the base of the fin. This motion induces an undulatory wave which travels from the leading edge to the trailing edge of the fin. It is thought that this undulatory wave is passively induced, and hence, the kinematic waveform is largely influenced by the fin's structure. Recent work focusing on bony fishes and models of their fins has shown that fin models with internal structure (fin rays) show different kinematic waveforms than models made of a single material, but our understanding of which structural parameters of fin rays are most influential on kinematics is still developing. Our goal was to understand the significance of internal structure for the swimming kinematics of chimaeras. We designed a physical modeling system based on the kinematic patterns of real chimaeras and examined artificial fins of varying fin ray diameter and packing density to investigate how internal anatomy influences pectoral fin tip amplitude, leading-edge curvature, and undulatory waves. As diameter and packing density increased, fin tip amplitude and leading-edge curvature decreased. Diameter had a much larger effect on fin tip amplitude than packing density over the tested ranges. Surprisingly, undulatory wave speed was greatest in the most flexible fin models rather than the stiffest. Empirical evidence and the mathematical equations stating that wave speed increases with stiffness run counter to this last result, suggesting our findings align with a more nuanced relationship between fin stiffness and wave kinematics described by a mathematical fluid flow model. Our work provides new insights into the anatomical parameters that could influence the evolution of chimaera flapping flight and pectoral fin locomotion more broadly and provides direction for possible biomimetic applications.</p>","PeriodicalId":13666,"journal":{"name":"Integrative Organismal Biology","volume":"8 1","pages":"obag046"},"PeriodicalIF":2.0,"publicationDate":"2026-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13543312/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148897044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To test these alternative hypotheses, we compared ontogenetic changes in the performance of a novel locomotor behavior-waterfall-climbing-across five amphidromous species of gobiid fishes from the Pacific, Caribbean, and Indian Oceans. Two species climb waterfalls using an inching motion, a derived functional innovation that alternates movements of pelvic and oral suckers.

Among adults, net climbing speed (including rest) was similar across the three powerburst species and one inching species, but a derived, faster speed was observed in one inching taxon, suggesting greater functional diversity in the younger innovation. However, kinematic data indicate that similar performance levels can be achieved through multiple functional pathways.

These compounds may exert sex-specific effects, as male and female offspring often differ in their development even from very early phases of their ontogeny. It has been therefore hypothesized that females might strategically allocate different amounts of these yolk compounds depending on the sex of the embryo. To test this hypothesis, we conducted an observational study in a wild population of spotless starlings (<i>Sturnus unicolor</i>), measured yolk concentrations of androgens (testosterone and androstenedione) and antioxidants (vitamin E, vitamin A, and carotenoids) in freshly laid eggs, and molecularly sexed the embryos from those eggs. We found no evidence that embryo sex influenced the concentration of any yolk compound. These results suggest that sex-specific allocation is constrained, possibly due to mechanistic limitations, such as the tight temporal overlap between oocyte meiosis (when embryonic sex is determined) and yolk formation. We also conducted a systematic literature review of studies that tested the association between embryo sex and yolk androgens and/or antioxidants in birds. Most studies (73%) did not report any significant effect. Among those that did, effects were often context-dependent or potentially biased by the effect of embryonic metabolism due to late sampling after laying.

The potential ecological or physiological function (mating, feeding, swimming energetics) of this difference is also unknown. In this study, cephalofoil morphology was assessed by sex and maturity for bonnethead sharks in Biscayne Bay and Tampa Bay, Florida. Additionally, muscle biopsies were analyzed for stable isotope composition to explore potential associations with diet. Sharks were caught between May 2022 and May 2023 via longline (Biscayne) and gillnet (Tampa). Body measurements and dorsal and ventral photographs of the head were taken as part of a scientific workup and sharks were promptly released.

Shape coordinates were also analyzed with a Procrustes ANCOVA to test for differences among groups while controlling for covariates. In both Biscayne Bay and Tampa Bay, males and females had significantly different head shapes, but, contrary to previous hypotheses, the cephalofoils of both sexes became rounder at maturity. There was greater rounding in female cephalofoils than male, and females experienced greater changes in cephalofoil shape as they matured.

Vulnerability of species to rising temperatures is shaped by multiple factors, including the thermal environments they experience, their physiological tolerances, and the temperature dependence of key performance traits. Here, we investigated the thermal ecology and climate vulnerability of two co-occurring tropical agamid lizards from semi-arid Southern India: the arboreal generalist <i>Calotes versicolor</i> and the saxicolous specialist <i>Psammophilus dorsalis</i>. For both species, we measured microenvironmental temperatures using physical copper models in open and shaded microhabitats, and quantified field-active body temperatures (Tb), as well as measured preferred temperature range (Tpref), critical thermal limits (CTmin and CTmax), and determined thermal performance curves for sprint speed and bite force. Thermal vulnerability indices (thermoregulatory accuracy, habitat thermal quality based on physical models, effectiveness of thermoregulation, warming tolerance, and thermal safety margins) were calculated and we projected future performance declines under IPCC Shared Socioeconomic Pathways (SSP1-2.6, SSP2-4.5, and SSP5-8.5). Although both species experienced similar microhabitat temperatures, they differed in thermoregulatory strategies and vulnerability. The widely distributed <i>C. versicolor</i> had a wider Tpref range, higher CTmax, lower CTmin, and broader thermal tolerance range. This species also had greater thermoregulatory effectiveness in open microhabitats, lower deviations from preferred temperatures, and more favorable habitat thermal quality. In contrast, <i>P. dorsalis</i> displayed narrower Tpref range, lower CTmax, higher CTmin, narrower thermal tolerance, and reduced thermoregulatory accuracy and effectiveness. As a consequence, <i>P. dorsalis</i> was operating closer to its upper thermal limits and experiencing reduced warming tolerance. Sprint speed had higher thermal optima and narrower performance breadths than bite force in both species, rendering locomotion more sensitive to warming. Projections indicated minimal impacts on both sprint speed and bite force, even under high-emission scenarios. Nevertheless, for the saxicolous <i>P. dorsalis</i>, narrow warming tolerances and thermal safety margins, suggest potential vulnerability through other ecological and physiological axes. Our findings reveal that closely related co-occurring lizards can occupy different thermal niches and face unequal climate risks despite shared ambient conditions. Species differences in microhabitat specialization, rather than exposure alone, emerges as a key driver of thermal vulnerability, underscoring its critical role in shaping resilience to ongoing climate warming.</p>","PeriodicalId":13666,"journal":{"name":"Integrative Organismal Biology","volume":" ","pages":"obag041"},"PeriodicalIF":2.0,"publicationDate":"2026-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7619449/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148897066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The argument is advanced here that examples of tagmosis are not hard to find among echinoderms, a fourth major group of metameric animals; but the degree of tagmosis is weak in most cases. The first few segments of the axial skeleton are often conjoined as a perioral tagma (e.g., the jaws and other parts of the oral frame of asteroids and ophiuroids and the lantern supports of echinoids). Several segments beyond the oral frame unite the disc with the base of the arm in ophiuroids. Crinoid pinnules occur in groups along the arms as oral, genital, and feeding pinnules. Porcellanasterid seastars have cribriform organs along the marginal ossicles on the base of the arm for generation of respiratory currents. Well-developed podial pores and podia are restricted to basal segments of the ophiuroid genus <i>Ophiomusium</i>. Ambulacral plates of most post-Paleozoic echinoids occur in clusters that result in arcs of variable numbers of pore pairs and spine tubercles, giving rise to several non-cidaroid tagmatized patterns.
