Studies on the <i>EGFR</i> gene in humans and other species have demonstrated its pivotal role in regulating the sodium ion balance and mediating sodium and water reabsorption in the kidney's proximal tubules. However, the impact of <i>EGFR</i> gene in how the Yarkand hare (<i>Lepus yarkandensis</i>) adapts to extreme environmental habitat remains unclear. The Yarkand hare is a desert-dwelling animal with multiple adaptations to cope with drought. Given the important physiological function of <i>EGFR</i> gene, we strived to understand its role in arid environment and explore the molecular mechanism of drought tolerance in the Yarkand hare. We first performed segmental cloning of the CDS of the Yarkand hare <i>EGFR</i> gene. Then, we constructed the phylogenetic tree of the Yarkand hare's <i>EGFR</i> gene and compared it with that of other species. The results showed that the Yarkand hare was most closely related to the Tolai hare (<i>Lepus tolai</i>). Through quantitative reverse transcription polymerase chain reaction (RT-qPCR), we discovered that <i>EGFR</i> expression in the kidneys of the Yarkand hare was higher than in the allopatric Tolai hare from non-arid areas. Therefore, we hypothesized that <i>EGFR</i> gene overexpression in the kidney of the Yarkand hare may play a crucial role in drought adaptability. Subsequently, we inserted CDS of <i>EGFR</i> gene into a pcDNA3.1-EGFP expression vector to construct recombinant plasmid, which was transfected into HeLa cells and overexpressed. RT-qPCR demonstrated a notable and statistically significant increase in <i>EGFR</i> mRNA expression and western blot proved stable expression of this protein in HeLa cells. Through cell experiments, <i>EGFR</i> gene overexpression markedly enhanced the survival of Hela cells subjected to NaCl, H<sub>2</sub>O<sub>2</sub>, and heat stresses, increased superoxide dismutase activity, and decreased malondialdehyde content. In conclusion, these findings preliminarily suggest that EGFR might help the Yarkand hare adapt to extreme environmental conditions.

Recapture technique based on sounds as a specimen identification mark has barely been used for marine mammals. However, inferring abundance estimates from acoustic methods could enhance the accuracy and precision of population size assessments. Here, we tested the possibility of using signature whistles as individual marks for estimating the size of common bottlenose dolphin (<i>Tursiops truncatus</i>) populations. Data were continuously collected for 326 days in 2015-2016, by using a fixed acoustic device located in the Sicily Strait (Italy). The SIGID method was applied to identify Signature Whistles Types (SWTs) over 7,000 h of recordings. Eighty SWTs were detected as long as their stereotyped fundamental frequency contours were repeated in bouts of at least 6 renditions. The mean SWTs monthly recording rate resulted in 0.19 (<i>Standard deviation</i> = 0.16), with 20 SWTs recorded over 5 or more different encounters (until a maximum of 30 encounters). The Jolly-Seber model (with POPAN formulation) was run in Mark software to estimate the population size. The estimated population size resulted in 171 bottlenose dolphins (95% confidence interval = 137-215). Even if the detection and identification of signature whistles required crucial precautions, and animals could be detected differently from visual techniques, the population size estimate obtained was comparable with previous results based on physical marks data. These outcomes demonstrated that signature whistles can be considered a strongly effective tool for integrating traditional mark-recapture techniques with finely estimated dolphins' population abundances.</p>","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"71 4","pages":"409-418"},"PeriodicalIF":2.0,"publicationDate":"2024-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12491674/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145233828","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}

Brown-headed cowbird eggs, and those of other avian brood parasites, tend to be more spherical due to their greater relative width. The traditional explanation for this egg shape is that it, combined with the thicker eggshells, resists host puncture-ejection. However, very few North American hosts of the brown-headed cowbird actually engage in puncture-ejection and therefore wider eggs may instead provide greater contact with a host's brood patch during incubation, especially in large host nests. We tested whether greater egg width increased mean temperature and reduced temperature variation in brown-headed cowbirds by inserting temperature probes into brown-headed cowbird and house sparrow (<i>Passer domesticus</i>) eggs and placing them into red-winged blackbird (<i>Agelaius phoeniceus</i>) nests. House sparrow eggs are similar in appearance and in length to cowbird eggs, but are not as wide. We found no significant relationship between brown-headed cowbird egg width and mean incubation temperature. However, brown-headed cowbird eggs experienced less temperature variation than house sparrow eggs, and within brown-headed cowbird eggs, more spherical eggs experienced less temperature variation when accounting for differences in width. These results suggest that brown-headed cowbirds may have short incubation periods in part because their eggs exhibit less temperature variation over the course of incubation.

To prevent desiccation, some organisms possess unique adaptations to harvest water from infrequent and unpredictable rainfall, including several squamates (snakes and lizards). While most squamates consume precipitation as it pools in the environment, a small number engage in behaviors to enhance water collection by capturing precipitation from their own skin, referred to as rain-harvesting behavior (RHB). Details of this behavior remain unclear, particularly the sequence of behaviors associated with RHB. We developed a method to simulate rainfall to observe RHB in prairie rattlesnakes (<i>Crotalus viridis</i>) in situ and recorded 72 events in 94 snakes, the most robust sampling of RHB to date. Using video analysis, we describe the postures and kinematics of RHB and develop the first illustrated ethogram of this behavior for any vertebrate. Our results demonstrate that RHB contains fixed and variable patterns useful in cross-species comparisons and in exploring proximate causes of the behavior. In addition, we describe novel features of RHB including suspended head drinking, body levering, and drinking from neighboring snakes. Our results reveal RHB to be an intricate suite of movements and actions, some of which allude to acute sensory abilities of these animals that warrant further study. Furthermore, observations of RHB at dens and rookeries suggest a potential, novel benefit of snake aggregation is the formation of large, communal surfaces for rain harvesting. We suggest that the extremely elongated body plan of snakes may be well-suited for a rapidly deployed, modular rain-harvesting system effective at capitalizing on fleeting rainstorms characteristic of arid ecosystems of the world.</p>","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"71 1","pages":"1-13"},"PeriodicalIF":1.6,"publicationDate":"2024-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11847018/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143494476","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}
