This study explored diel activity patterns of the roe deer (Capreolus capreolus) across different study areas with varying levels of human disturbance and predator presence, specifically wolves (Canis lupus), located in northwestern Italy. We conducted seasonal camera-trapping sampling sessions for 2 years (2020-2022); we deployed 502 camera traps for a cumulative sampling period of 6,709.5 trapping days, and we collected 2,749 roe deer events. Roe deer exhibited generally bimodal diel activity patterns with peaks at dawn and dusk across all study areas, reflecting their crepuscular behavior. The consistency of the patterns can be attributed to biological constraints, such as mating and foraging needs, as observed during spring across all study areas, or to the absence of variations in perceived risks, as observed where human disturbance remains constant throughout the year. Interestingly, significant local and seasonal variations were also observed. Nocturnal activity varied seasonally and was influenced by landscape composition and predator presence, with lower nocturnal activity in modified landscapes during summer and autumn, likely due to favorable daytime conditions, and lower nocturnal activity in areas with stable wolf presence, particularly in winter, suggesting an antipredator response. Our results indicated that roe deer adapt their activity patterns to mitigate risks, demonstrating behavioral plasticity in response to the environment. This behavioral adaptability may be a key trait that facilitates the expansion of the species into highly anthropized landscapes, allowing roe deer to thrive in increasingly urbanized environments.","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"72 3","pages":"341-353"},"PeriodicalIF":2.1,"publicationDate":"2025-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13290407/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148334155","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}

Additionally, because fighting can involve vigorous activity, engaging in a fight can make the opponents more noticeable to predators. Thus, predation risk, alongside resource value (RV), may interact with the effects of RHP difference. During hermit crab contests over the ownership of empty gastropod shells attackers perform vigorous shell rapping, whereas defenders adopt a protective posture inside their shells. This role asymmetry provides an opportunity to decompose the effects of motivation and predation risk on fighting as both will be influenced by the visual contrast of the shells against the substrate. If attackers are sensitive to RV, their agonistic behavior should vary with the color of the defender's shell and if they are sensitive to predation risk, it should be influenced by the color of their own shell, due to the vigorous way it moved during shell rapping. We found that the most vigorous fights, with the greatest chance of victory for attackers, occurred when both shells were of high contrast, indicating that RHP advantage is modulated by both RV and potential predation risk. Moreover, this shows how even relatively subtle features of a contested resource, such as color, and modify the effects of fighting ability during animal contests.","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"72 3","pages":"333-340"},"PeriodicalIF":2.1,"publicationDate":"2025-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13290402/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148334088","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, these antipredator adaptations can be costly, if they unnecessarily draw attention to the prey animal. Thus, animals with elaborate antipredator traits may be under pressure to selectively increase advertisement of their defenses in particular contexts. The matador bug, Bitta alipes (Hemiptera: Coreidae), possesses large, colorful flags on its hind tibia that it uses in a stereotypic \"waving\" behavior. Previous research found no evidence that this waving behavior is employed in social or sexual interactions. Here, we experimentally tested for a potential antipredator function of flag waving by exposing a matador bug to either an arthropod predator (praying mantid) or a similarly sized nonpredatory arthropod (nonpredatory katydid). In total, we recorded 2,938 leg waves among 25 individuals. We found that matador bugs' waving behavior increased in duration, frequency (number of wave bouts), and intensity (number of waves per bout) in the presence of praying mantids. Notably, we found on average a 7-fold increase in the number of waves in the presence of a mantid relative to a similarly sized nonpredatory arthropod. Praying mantids consumed very few matador bugs (3/25) and never attacked bugs that were waving, lending support to the hypothesis that flags serve an antipredator function in matador bugs. We find similar flag-waving behavior in at least 5 closely-related flag-legged bug species, all of which have expanded tibial flags with contrasting coloration and are Passiflora specialists, providing opportunities for future studies to examine the evolution of elaborate flag-waving behavior as an antipredator behavior in this group.","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"72 2","pages":"293-302"},"PeriodicalIF":2.1,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13202313/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148044498","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}

Among these, ecologically relevant stressors such as predation risk remain understudied despite their potential to disrupt maternal physiology and placental function. In this study, we investigated how prenatal exposure to predator odor influences placental glucocorticoid metabolism and fetal growth in Brandt's voles (Lasiopodomys brandtii). Pregnant voles were exposed to predator odor to simulate prenatal predator stress, allowing us to assess its effects on fetal growth, maternal and fetal corticosterone levels, and the expression of key enzymes and transport proteins involved in glucocorticoid regulation. The results revealed that prenatal exposure to predator odor significantly reduced fetal weight. While maternal and fetal serum corticosterone levels increased, placental corticosterone levels remained unchanged. Additionally, our study observed significant increases in the expression of placental P-glycoprotein and 11β-hydroxysteroid dehydrogenase 1, both of which are crucial for maintaining placental glucocorticoid metabolic homeostasis. However, 11β-hydroxysteroid dehydrogenase 2 levels were unaffected. In the fetal brain, corticotropin-releasing hormone expression in the hypothalamus showed a downward trend, whereas glucocorticoid receptor expression in the hippocampus remained unchanged, indicating a disruption in the development of the hypothalamic-pituitary-adrenal axis. These findings suggest that prenatal exposure to predator odor alters placental glucocorticoid metabolism, leading to increased fetal corticosterone exposure and potentially impairing fetal development.","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"72 2","pages":"273-282"},"PeriodicalIF":2.1,"publicationDate":"2025-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13202339/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148044473","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}

The Chinese pangolin, once widespread in southern China and Asia, underwent severe range and population declines in the late 20th century. We studied habitat selection and distribution changes of the Hainan subspecies (M. pentadactyla pusilla, hereafter, the Hainan pangolin) over 3 decades using transect and camera-trap data (1990s-2020s) from Jianfengling, Hainan. Findings revealed that Hainan pangolins predominantly selected habitats characterized by relatively high humidity (Precipitation of Driest Month >20 mm), higher elevations, and steeper slopes. Specifically, they exhibited distinct preferences: a preference for north-facing aspects in the 1990s and for smaller daily temperature variations (mean diurnal range <6.6 °C) in the 2020s. Critically, pangolins used habitats near roads and forest edges (particularly within natural forests in the 2020s, likely linked to food availability) where human disturbance concentrates, but concurrently preferred higher elevations and steeper slopes to mitigate anthropogenic pressures. Over the past 3 decades, the habitat in Jianfengling decreased by 26%, with some habitat loss occurring in the north and new habitats observed in the south. Conservation efforts should prioritize protecting mountainous regions with humid and warm climates. Strengthening afforestation initiatives and enforcing strict hunting prohibitions are recommended to ensure sustainable recovery for this vulnerable species. This study underscores the importance of incorporating multi-period habitat selection data into conservation strategies for endangered species.","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"72 2","pages":"283-292"},"PeriodicalIF":2.1,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13202338/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148044485","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}

We quantify wasp behavior during partner sampling using day censuses and recording aggregations. We found that wasps preferentially aggregated at specific locations, without resources or nests, consistent with the formation of a \"social lek.\" In aggregations, wasps engaged in a range of aggressive interactions. At the beginning of the shopping period, wasps engaged in more intensely aggressive behavior and they observe conspecifics fight.

In the Moscow region, we examined 37 wintering males of great tit (Parus major) to evaluate the magnitude and direction of the relationship between nonspecific constitutive immunity (NCI) and two traits reflecting energy expenditure and balance. The first, basal metabolic rate (BMR), represents the energetic cost of self-maintenance in endotherms and could serve as an indicator of maximum sustainable work output. The second, body mass, acts as a proxy for a bird's current physical condition. We hypothesized that under the harsh midwinter conditions, when males begin to exhibit territorial behavior, a trade-off would likely emerge between their costs of maintaining NCI and BMR during the territory partitioning phase. We used a hemolysis-hemagglutination assay to assess NCI and flow-through respirometry to estimate BMR. Our results revealed an age- and condition-dependent relationship between body mass and NCI, alongside a consistently negative relationship between NCI and BMR across age groups and years. This negative relationship indicates a trade-off between energy allocated to self-maintenance and NCI. Previously, we demonstrated that an improved social and territorial status in male great tits was associated with increased energy expenditure, either through elevated BMR or higher daily energy expenditure. We propose that the energetic cost of NCI arises indirectly due to hormonal shifts associated with changes in social status. Our findings underscore the complex interplay between physiological and ecological pressures in shaping life-history strategies.","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"72 2","pages":"211-222"},"PeriodicalIF":2.1,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13202321/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148044475","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}
