Lizards have become a model in the study of SSD, as they show either monomorphism, male- or female-biased SSD. Variations in the strength of intrasexual selection (assumed to favor larger body size in males) and fecundity selection (assumed to favor larger body size in females) are usually considered the main reasons for variation in SSD. Here, we take advantage of a 2,200 m elevational gradient for studying the elevational variation in SSD in the Mediterranean lizard <i>Psammodromus algirus</i>. Previous studies on this species suggest that the strength of sexual selection decreases with ascending elevation, while the strength of fecundity selection on females increases with ascending altitude. Accordingly, we predicted that SSD bias to males should increase at low elevations, while female-biased SSD should increase at high altitudes. We found that both males and females were larger with ascending elevation, but the magnitude of variation in body size with altitude differed between sexes. Females were slightly larger than males (1.1%), although SSD bias toward females increased with elevation. SSD was male-biased only in one locality, at the lowest elevation. Nevertheless, elevational differences in SSD resulted from a concomitant sexual variation in age structure, as females were older than males in every locality except at the lowest elevation, where males were older than females. Since this species shows post-maturational growth, sexual differences in age structure could explain the elevational pattern in SSD.</p>","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"72 1","pages":"138-146"},"PeriodicalIF":2.0,"publicationDate":"2025-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13045821/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147624706","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}

Environmental variables in ectotherms' natural nests may drive their adaptive life-history evolution. To investigate the effect of variations in nest temperature, moisture, and vegetation cover on the reproductive phenotype and embryonic development of <i>Phrynocephalus przewalskii</i>, we selected two populations that inhabit environments with different vegetation cover. We also conducted a reciprocal egg swap experiment to analyze the effects of nest environment and population origin on embryonic and offspring development. Although fine-scale environmental heterogeneity was detected between low- and high-vegetation-cover populations, no significant differences in female reproductive characteristics, including clutch size, average egg mass, clutch mass, and relative clutch mass, were observed between populations. However, we found that egg incubation period and hatching success were influenced by the nesting environment. Specifically, individuals that grew in low-vegetation-cover sites had shorter incubation periods and higher hatching success rates than those in high-vegetation-cover sites. The hatchling growth rate was significantly higher in the high-vegetation-cover population, yet the overwintering survival rate was higher in the low-vegetation-cover population. These results indicated that fine-scale habitat heterogeneity does not significantly affect the reproductive output of female lizards, offspring growth, or survival rates. However, it does affect embryonic development, including the incubation period and hatching success. Our study highlights the effects of fine-scale habitat heterogeneity on female reproduction and embryonic and offspring development and suggests that desert toad-headed agamas may be resilient to variations in environmental conditions associated with desertification.</p>","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"72 1","pages":"106-115"},"PeriodicalIF":2.0,"publicationDate":"2025-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13045823/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147624184","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}

Across 14 fair sites in West Bengal, India, we explored how human footfall and resource availability impact dog distribution and behavior. These fairs are typically held in open grounds during the winter and spring seasons, so data collection occurred from December to March, in two phases. Three randomly selected days during the fair were used for sampling in three sessions per day. Employing spot census, scan sampling and video recording, observers documented GPS locations, sex, and instantaneous behaviors of FRDs. There was a notable increase in human flux during the middle phase of the fair on a day, while dog abundance increased during the end phase. Dogs predominantly foraged, exhibited gait, and remained vigilant, their numbers were positively associated with resource availability. Proximity of territories to the fairground significantly shaped dog behavior; dogs closer to the fair demonstrated the consistency of presence, implying efficient resource utilization. Conversely, dogs from farther distances exhibited lower consistency and a \"grab-and-go\" strategy, suggesting cognitive adaptations to resource scarcity and competition. These findings lend support to the Resource Dispersion Hypothesis and underscore the intricate relationship between human activity, resource availability, and the behavior and cognition of FRDs during seasonal fairs. They offer insights into the ecological dynamics of FRDs in human-dominated landscapes, emphasizing the necessity for comprehensive management strategies in urban and peri-urban environments.</p>","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"72 1","pages":"116-126"},"PeriodicalIF":2.0,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13045819/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147624735","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 impacts, the disruption of natural flow variability remains a critical but under-analyzed factor, particularly regarding its influence on riparian waterbirds. To address this gap, we investigated the behavioral responses of the endangered Scaly-sided Merganser (<i>Mergus squamatus</i>), a wintering diving duck, to dam-induced hydrological fluctuations downstream of the Taoyuan Dam in Hunan Province, China. Using scan sampling and Multivariate Bayesian Generalized Additive Models (GAMs), we assessed the relationships between bird activity patterns and water level dynamics. Our results reveal that increased water level and rate of change are associated with heightened foraging activity and a concurrent reduction in resting and preening. These shifts likely reflect changes in prey accessibility driven by fluctuating flow conditions. Based on these findings, we recommend modulating dam outflows to 3000 m³/s during peak foraging hours and reducing discharge to 2000 m³/s during midday and night. Our study underscores the potential of incorporating waterbird behavior into dam operation strategies for balancing ecological integrity with energy production.</p>","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"72 1","pages":"127-137"},"PeriodicalIF":2.0,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13045832/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147624532","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}
