Despite extensive research, the mechanisms underlying food sharing remain debated. Moreover, the majority of studies on food sharing in non-human animals have been conducted under controlled environments. The natural behavioral characteristics and ecological factors influencing the natural selection of food sharing are still not well understood. In this study, we introduce a method to examine food-sharing behaviors in wild birds within their natural habitat. Using two types of feeders-one permitting food sharing with conspecifics and the other providing exclusive access to food-along with infrared cameras to record feeder-triggering events, we found that azure-winged magpies did not exhibit proactive food-sharing behaviors. However, they did exhibit passive food-sharing behaviors under conditions of low food availability. Consistent with the harassment-avoidance hypothesis, the birds prioritized the sharing feeders to decrease harassment from food snatching when food was limited. These findings suggest that food sharing is likely shaped into a passive behavioral pattern under limited resources conditions, which induce conflicts within social groups. This context-dependent strategy may effectively reduce harassment costs, optimize individual access to resources to maximize individual benefits, and potentially enhance the survival of other group members.","PeriodicalId":13654,"journal":{"name":"Integrative zoology","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144952887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As such, research seeks to better understand variation in amphibian skin traits. One source of variation that is poorly understood is seasonal variation in amphibian skin thickness that has been reported in two anurans and one caudatan. It is currently unknown how widespread this trait is among amphibians, or the pattern it follows throughout the year, because existing studies have only sampled specimens at two or three times of the year. We use museum specimens of three sympatric anurans from the northern United States to test for the presence of seasonal changes in skin thickness and which functional hypothesis best explains the pattern: either an environmental function/response or an intrinsic life history-related pattern. Seasonal changes in skin thickness were detected in all skin regions and layers measured in the American bullfrog (Lithobates catesbeianus), in some of the skin layers of the northern leopard frog (L. pipiens), but such changes were not detected in spring peepers (Pseudacris crucifer). The results favored the life history functional hypothesis, where skin is thinnest after brumation, increasing in thickness throughout the year ahead of hibernation. The differences between skin thickness variables between early- and late-year specimens of L. catesbeianus were as high as 40%, indicating that this source of variation has the potential to skew the results of morphological studies of amphibian skin thickness if not controlled for.","PeriodicalId":13654,"journal":{"name":"Integrative zoology","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144952980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Electron microscopy imaging has emerged as a pivotal method for such observations, yet accurate identification remains challenging due to the high density, mutual occlusion, small size, and diverse postures of the targets. To date, no research has systematically addressed these issues, limiting progress in biological microscopic research. Here, we introduce an improved YOLOv8n model for detecting the bird feather hooklet, a typical microscopic target within electron microscope images. The improved model incorporates three modules: gather-excite attention mechanism (global-local feature integration), explicit visual center (EVC) module (small-object detection enhancement through global and local feature fusion), and Shape IoU loss function (bounding-box regression optimization for posture variations). The experimental outcomes demonstrate that, compared to the baseline model, the improved YOLOv8n achieves a 3.5% increase in precision, a 9.1% boost in recall, and a 5.7% improvement in mAP50, along with 4.4% and 6.3% gains in mAP50-95 and F1 score, respectively. These advancements demonstrate the improved YOLOv8n model's effectiveness in detecting occluded, aggregated, and multi-posed hooklets at the nanometer level, offering new insights into feather structure-function relationships and advancing ornithological research. This study not only highlights the great potential of the improved YOLOv8n model in complex object detection but also emphasizes its application significance in micro-precision biological research.","PeriodicalId":13654,"journal":{"name":"Integrative zoology","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144952906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work aimed to apply the principles of skin mark analysis to a cetacean species to test its ability to identify sex differences in markings and build a sex-discrimination model exclusively based on photographic material. The common bottlenose dolphin (Tursiops truncatus) was chosen as the model species, and skin marks and their progression over time were identified and measured across the whole-body surface of individuals on photographs acquired between 2016 and 2023 in the Tiber River Estuary area. Interactions with fisheries were quantified both as the proportion of encounters in presence of trawlers, and as a probability of fishing gear injuries. Non-parametric tests were used to assess sex-specific differences. A generalized linear model with binary response (sex) was built through a stepwise procedure, using mark-based indices as predictors. Relevant differences between sexes emerged in markings, with males presenting more social, aggression-related, and fishing-related marks overall, and a stronger tendency of mark accumulation over time. The estimated model reflected the differences highlighted by the statistical tests and had a high accuracy and sensitivity toward both sexes. These results highlight the feasibility and efficacy of this methodological approach to sex-ratio investigations and identify differences in anthropic pressures insisting on males and females, with important conservation implications. The exclusive use of photographic material makes this methodology potentially applicable and adaptable to multiple species and environments, aiding the efforts of conservationists worldwide.","PeriodicalId":13654,"journal":{"name":"Integrative zoology","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144952975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whether factors such as breeding site type influence weaponry evolution remains an open question. We explored this question using frogs of the subfamily Leptodactylinae, where males of species that spawn in exposed sites (water bodies) fight to hold oviposition sites or dislodge rivals during amplexus. Conversely, males of species that spawn in concealed sites (ground nests and crevices) rarely engage in physical contests. We hypothesized that male weaponry evolution would be associated with reproduction in exposed sites. Using two complementary phylogenetic comparative methods, we first found that both gains and losses of weapons occurred more frequently in species spawning in exposed sites. This unexpected finding suggests that the dynamics of weaponry evolution are more intricate than anticipated. Second, we found a macroevolutionary correlation between male weapons and breeding site type: the presence of weapons is associated with exposed sites, while their absence is associated with concealed sites. We explore how additional factors, such as population density, the energetic costs of producing and maintaining weapons, and female choice, may also influence this macroevolutionary pattern. Finally, we hope our findings stimulate further investigations into weaponry evolution in other clades of external fertilizers.","PeriodicalId":13654,"journal":{"name":"Integrative zoology","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144952941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Spiders are intriguing models to test this hypothesis, as sociality is rare in this usually solitary and aggressive group. Here, we used microCT to compare the central nervous system and brain volumes between social and solitary females of the species in two taxonomic groups, huntsman and crab spiders. Overall, we found no difference in relative CNS and brain volume between social and solitary species. However, social huntsman spiders Delena cancerides had larger arcuate and mushroom bodies than the solitary huntsman species Isopeda villosa and Heteropoda jugulans. Social crab spiders Xysticus bimaculatus had larger visual neuropils than the solitary species Thomisus spectabilis and Tharrhalea evanida. Social huntsman spiders exhibit intricate social behavior, including prey sharing and kin recognition, which could explain the higher investment in brain structures that are related to cognitive integration. They also had smaller venom glands, possibly due to their prey-sharing behavior. In social crab spiders, the low-light leafnest may have driven enlarged visual neuropils. Some variations in specific brain regions between solitary and social species were consistent with the social brain hypothesis, but the patterns differed between lineages. Thus, it is likely that other ecological drivers affect the development of specific brain regions in spiders. Our study provides the essential knowledge platform to conduct experimental manipulations of social and environmental conditions on these spiders to directly test their impact on brain structures, coupled with tests of relevant behavior.","PeriodicalId":13654,"journal":{"name":"Integrative zoology","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144953047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most GRs showed higher transcript accumulation in the pectines, rather than other tissues, aligning with their known chemosensory function and highlighting the remarkable significance of pectines as crucial sensory organs. Conversely, IRs/iGluRs overall exhibited a more widespread distribution throughout the different tissues of the scorpion body.

This study exposed zebrafish embryos (≤4 h post-fertilization, hpf) to OC and EHS (0.05, 0.5, 5, and 50 mg/L) until 120 hpf. Both chemicals induced developmental abnormalities, including deformities and reduced heart rates. Exposure to 50 mg/L EHS resulted in 54.72% mortality, while the same concentration of OC caused 13.33% mortality at 96 hpf, indicating higher acute toxicity of EHS. Behavioral assays revealed that 50 mg/L OC and 5 mg/L EHS induced hyperactivity, whereas 50 mg/L EHS caused locomotor suppression, suggesting neurodevelopmental toxicity. Transcriptomic analysis showed OC regulated hypoxia response, cytochrome P450, and extracellular matrix, while EHS affected immunity, nucleotide/amino-sugar metabolism, and lipid homeostasis. Oxidative stress biomarkers (superoxide dismutase, glutathione peroxidase, and glutathione) and triglyceride (TG) levels were monitored. Both chemicals induced oxidative stress, but only EHS significantly upregulated TG, disrupting lipid metabolism. These findings highlight that EHS exhibits broader and more severe toxicity than OC, emphasizing the need for further research and regulatory measures to mitigate the ecological risks of these UV filters.","PeriodicalId":13654,"journal":{"name":"Integrative zoology","volume":" ","pages":""},"PeriodicalIF":3.7,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144952924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
