To demonstrate its utility, the method was applied to several large elasmobranch species, which are typically highly challenging to measure. Using motion tracking software, we analyzed video footage of wild and captive sharks to track their instantaneous position and speed. In order to estimate the force output, we used the tail/body motion based on the swimming modes of the fish to calculate the water displaced by this motion during locomotion. Using Newton 3rd law, we have calculated the instantaneous force exerted by the water on the shark. The force output, that is thrust was calculated by averaging the instantaneous force over the tailbeat cycle. The thrust, for each fish was converted into a nondimensional parameter defined as: scaled thrust, allowing comparisons independent of size based on prior knowledge of the fish length and mass. This scaled thrust was analyzed for various swimming modes and caudal fin morphology to correlate to behavioral features through principal component analysis (PCA) we demonstrate the coupling between morphological traits and hydrodynamic forces. For the species studied the ratio of the upper to lower lobe of the caudal fin (CLAR) emerged as a strong predictor of scaled thrust, accounting for more than 80% of the observed variation. Our findings for the species studied indicate that coastal pelagic species exhibited lower scaled thrust values than benthic species, suggesting that benthic species may be less efficient, expending more energy to remain aloft or compensate for drag relative to generating forward motion. We propose that the unique ecological niches of these species drive behavioral changes that result in morphological adaptations to optimize performance.</p>","PeriodicalId":11467,"journal":{"name":"Ecology and Evolution","volume":"15 7","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ece3.71660","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144492834","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, there is insufficient ecological data to determine its distribution adequately, and the species has only been sporadically caught in live trapping surveys, with no population size estimates. In the present study, eastern barn owl (<i>Tyto javanica delicatula</i>) pellet analysis was used to assess a range of locations for the presence of the Julia Creek dunnart as a prey species. Owl pellet deposit sites were chosen to encompass areas of high, medium, and low likelihood of Julia Creek dunnart occurrence based on Australian Government habitat models for the species with the goal of better understanding the species' distribution. In the analysis, Julia Creek dunnarts were present at four (of nine) locations, including all high-likelihood locations, half of the medium-likelihood locations, and no low-likelihood locations. This result supported the accuracy of the Australian Government habitat models. Results also demonstrated the importance of the long-haired rat (<i>Rattus villosissimus</i>) in the eastern barn owl diet during plague years. The research will assist with prioritizing sites for protection and monitoring of the Julia Creek dunnart.

However, the effects of ultraviolet (UV) radiation on copepods in marine systems, especially at tropical and subtropical latitudes, are not well understood. Incubations in UV and non-UV treatments during outdoor solar experiments at a subtropical latitude where copepods dominated the zooplankton community demonstrated that UV exposure led to 40%–50% higher mortality than in non-UV treatments after 4 h of exposure. In outdoor plankton migration tower experiments, most copepods avoided surface waters regardless of radiation treatment. While adaptations to avoid UV damage, such as the accumulation of photoprotective compounds, were observed in copepods, they were insufficient to fully mitigate UV-induced harm. Thus, surface avoidance is likely the primary adaptation employed by copepods and other zooplankton to evade UV exposure. This study expands upon existing UV research, which has largely focused on high-latitude and high-altitude ecosystems, suggesting that UV is a major environmental threat factor for low-latitude zooplankton.

The study investigated how Lesser Adjutant Storks (<i>Leptoptilos javanicus</i>) adjust their behavior in response to human disturbance in the Janakinagar-Murtiya Important Bird and Biodiversity Area of Nepal. Using the Focal Animal Sampling method, we captured 600 min of video footage along road transects during the summer of 2023 and winter of 2024. The analysis revealed significant seasonal shifts. During the summer, vigilance dominated the activity budget (47.18%), while feeding was comparatively low (15.06%). In contrast, during winter, storks prioritized feeding (30.33%) over vigilance (23.32%). Kruskal–Wallis and Dunn's post hoc tests confirmed that both feeding and vigilance varied significantly across seasons (<i>p</i> < 0.05), suggesting that species adjust their time budgets based on resource availability and predation risk. Moreover, multinomial regression analysis indicated that human disturbance significantly influenced vigilance, with storks in high disturbance areas displaying greater vigilance than those in low disturbance areas (<i>p</i> < 0.05). These findings were further supported by a Likelihood Ratio Test (LRT = 263.82, df = 6, <i>p</i> < 0.05), confirming that disturbance level had a significant effect on behavioral variation. Collectively, the study suggests that vigilance behavior increases in both frequency and intensity under higher disturbance, potentially at the cost of feeding time and energy intake.

We provide a comparative analysis of the association between the measure of maturity and habitat use during the non-breeding period, contrasting coastal and inland wetland habitats.

This phenomenon provides strong support for the “host activity hypothesis.” The nest defense behavior exhibited by the gray bushchat aimed at protecting its nest, inadvertently provided cues to the common cuckoo regarding its nest site.
