In this study, we show that the urea cycle is selectively regulated rather than broadly suppressed in torpid bats. A significantly increased abundance of carbamoyl-phosphate synthase 1 (CPS1) maintained its functional capacity during torpor and arousal in Myotis ricketti. Proteomic analyses and confocal microscopy identified a specific association and co-localization between CPS1 and agmatinase (AGMAT), an ATP-independent enzyme involved in nitrogen metabolism. Co-localization of CPS1 and AGMAT was also observed in torpid Rhinolophus ferrumequinum, a phylogenetically distant species. Fluorescence resonance energy transfer (FRET) further supported an indirect CPS1-AGMAT interaction. Most urea cycle enzymes exhibited stable or only moderately reduced expression during bat torpor, and metabolic profiling demonstrated sustained nitrogen flux. Together, these findings reveal a conserved adaptive mechanism that maintains urea cycle function, potentially enhancing osmotic stability and energy efficiency during prolonged fasting and water scarcity.","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://academic.oup.com/cz/advance-article-pdf/doi/10.1093/cz/zoag002/66270387/zoag002.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147912237","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 phenomenon is exemplified by certain spiders that construct bell-shaped cobwebs using sand grains, soil particles, prey remains, and plant debris. The retreat and gumfooted lines in these cobwebs are believed to serve defensive and foraging functions. This study aimed to test both the phenotypic plasticity and the tradeoff hypotheses by examining whether the common cobweb spider Campanicola campanulata alters web architecture and behavioral investments in response to variations in prey availability. When prey availability increases, spiders build webs higher, construct smaller and lighter retreats, and produce cobwebs with fewer gumfooted lines and smaller capture areas. Results indicated that, in the presence of abundant ant-prey, spiders reduced their investment in both foraging and defense. These findings suggest that the web architecture of C. campanulata exhibits a high degree of plasticity in response to variation in prey availability, but investment in web architectures does not involve tradeoffs between foraging and defense.","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"72 4","pages":"590-599"},"PeriodicalIF":2.1,"publicationDate":"2025-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13500169/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148809412","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}

Snakebite envenoming is estimated to cause approximately 63,400 deaths annually, mostly in tropical and developing countries. However, few studies have comprehensively assessed the future global patterns of envenomation risk, particularly across venom types with differing clinical and ecological characteristics. In this study, we modeled the current and future distributions of 193 medically important venomous snake species (neurotoxic and hemotoxic) under 4 climate change scenarios through 2100. We assessed 3 indices to quantify snakebite risks: the Venom Richness Index (VRI) for species-specific venom diversity, the Snakebite Range Expansion Index (SREI) to capture range expansion or contraction, and the Venom Overlap Index (VOI) for geographic co-occurrence of venom types. We found that snakebite risk is projected to increase in temperate and cold regions under high-emissions scenarios, with VRI and SREI increasing in areas such as North America, Europe, and East Asia. In contrast, VRI and SREI are projected to decline across parts of tropical Africa, India, and southern China. VRI transitions are projected to expand in northern Mexico, Brazil, Spain, southwestern China, and southern Australia, increasing the potential for diagnostic uncertainty and treatment complexity. VOI is expected to rise in highly populated but poorly urbanized regions, highlighting the vulnerability of developing countries with limited infrastructure. These spatial and venom-specific shifts underscore the need for regionally tailored antivenom strategies, improved diagnostics, and high-resolution risk forecasting to mitigate the future burden of snakebite under global change.","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"72 4","pages":"579-589"},"PeriodicalIF":2.1,"publicationDate":"2025-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13500158/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148809395","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}

Passerine birds may potentially select for accurate mimicry, but studies focused on their responses to ant mimics are surprisingly very scarce. In this study, we tested great tits (Parus major) as predators using photographs of ant-mimicking spiders, ants, and non-mimetic spiders to investigate the importance of morphological and chromatic traits for generalization from ant models to ant-mimicking spiders. Birds were divided into 2 groups, each trained to discriminate between non-mimetic spiders and either monochromatic (black) or dichromatic (black-reddish) ants, before being tested with mimics. Once birds from both groups learned to categorize correctly non-mimetic spiders and ants, they subsequently avoided morphologically accurate mimics, but only the birds trained to avoid dichromatic ants avoided morphologically inaccurate dichromatic mimics (e.g., Micaria sociabilis). Our results suggest that morphological and chromatic traits both play important roles in ant mimicry and chromatic traits can compensate for inaccurate morphological mimicry. Furthermore, classification of mimetic accuracy by birds corresponded roughly to the classification by humans.","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"72 4","pages":"568-578"},"PeriodicalIF":2.1,"publicationDate":"2025-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13500164/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148809456","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 trade-off requires balancing time spent being vigilant with time spent feeding under predation risk, influenced by both individual and social factors. However, it remains unclear which factor plays a more significant role. In this study, we aimed to determine whether individual factors (sex, personality, and body condition) and social factors (social familiarity and social rank) influence feeding and vigilance behaviors under predation risk. When alone with the predator, budgerigars with longer tarsus length exhibited shorter latency to feed, and bold budgerigars tended to have a lower frequency of scans, but neophobia and body condition did not influence these behaviors. When facing the predator with familiar group members, individuals showed shorter latency to feed, and a lower frequency of scans compared to when with unfamiliar group members or alone. Moreover, social rank was the most important factor affecting latency to feed. Our findings suggested that both individual and social factors can influence budgerigars' foraging behaviors, with social factors playing a more significant role than individual factors when individuals are in a group.","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"72 4","pages":"557-567"},"PeriodicalIF":2.1,"publicationDate":"2025-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13500172/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148809476","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 study examined the relationship between ambient temperature and thermal behavioral strategies during resting periods in mantled howler monkeys (Alouatta palliata) across 3 sites in Veracruz, Mexico: Agaltepec (AGA; 28.4 ± 4.7 °C), Mirador Pilapa (MP; 28.8 ± 2.1 °C), and Zapoapan (ZAP; 28.9 ± 2.5 °C). We used focal-animal sampling, randomly selecting individuals and recording the time invested in each posture and the tree stratum in which they rested, and the ambient temperature. All statistical analyses were performed independently between sites. The results indicate that, across the 3 study sites, a consistent pattern of posture adopted within specific tree strata was observed, despite differences in altitude, vegetation, and ambient temperature. We found a strong positive correlation between lower temperatures and the time recorded in the semi-fetal posture in the high strata (Rc > 0.7547), and between higher temperatures and the time recorded in the extended posture in the low strata (Rc > 0.6803). These results suggest howler monkeys combine posture and vertical positioning to optimize thermoregulation. However, as temperatures rise, the preference for extended postures in lower strata-where temperatures may be cooler-leads to longer rest periods. This behavioral shift could reduce feeding and hydration, potentially increasing the risk of dehydration or heat stress under future climate conditions.","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"72 4","pages":"512-522"},"PeriodicalIF":2.1,"publicationDate":"2025-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13500170/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148809418","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}
