However, causal evidence from manipulative studies, particularly for vertebrates, remains scarce. Prolonged temperature increases, a direct consequence of climate change, pose significant challenges to species adaptation and survival. We examined the effects of prolonged temperature increases on reproduction, physiology, and behavior adaption in the greater long-tailed hamster using semi-natural enclosures where temperature was manipulated via plastic roofs and windows, creating a greenhouse effect without affecting rainfall. We analyzed data using grouped enclosures (low temperature, LT; high temperature, HT), which showed that prolonged temperature increases led to reduced reproductivity per capita during the breeding season. In addition, prolonged temperature increases reduced night-time activity in founder hamsters during overwintering, increased burrow depth during the breeding season, and raised testicular weights in founder males during the overwintering season. Our study provides experimental evidence that prolonged temperature increases negatively impact population growth of greater long-tailed hamsters by inducing temperature stress and impairing reproductive performance, highlighting the need to address heat stress in wildlife management under climate warming.","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"71 6","pages":"788-800"},"PeriodicalIF":2.0,"publicationDate":"2025-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12742388/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145851441","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}

With the rise in global temperatures due to climate change, concerns have arisen about the spread of southern malaria species, that potentially can affect previously unexposed bird populations. We studied juvenile siskins infected with two distinct malaria parasites: Plasmodium relictum (SGS1 lineage) and P. ashfordi (GRW2 lineage). While the former is common in the Northern Palearctic, the latter is primarily found in Central and Southern Africa. We assessed the impact of these infections on siskins' physiological well-being using resting metabolic rate (RMR) and interleukin-6 (IL-6) levels. Changes in RMR reflect the energetic cost of disease, while IL-6 serves as a one of the inflammatory cytokines in the innate immune system's response to infection. Our experimental findings reveal distinct outcomes during the acute phase of SGS1 and GRW2 infections. Infection with SGS1 was marked by reduced RMR and IL-6 levels in siskins. A similar IL-6 pattern was observed in the GRW2 group initially, though it was not sustained. Additionally, GRW2-infected siskins showed distinct RMR dynamics compared to SGS1-infected birds. Our study did not conclusively demonstrate that tropical malaria has more severe effects on siskins. However, similarities with previous studies with SGS1 infected birds and variations in disease progression between the two experimental groups underscore the complexity of host-parasite interactions in avian malaria infections.","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"71 6","pages":"773-787"},"PeriodicalIF":2.0,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12742392/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145851408","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}

In humans, screams activate the amygdala and are perceived as less positive than spoken words. We conducted a playback experiment to see if two skink species (one of which is known to negatively respond to nonlinearities) responded differently to human spoken words and screams. We broadcast short phrases of humans screaming, humans speaking, or a control, a novel bird song. We studied the immediate response by quantifying the change in rates of vigilance and locomotion. We also studied a slightly delayed response in risk assessments by measuring skink flight initiation distance after the playback. Furthermore, we conducted experiments in nonresidential and residential areas to understand how human exposure may influence human discrimination and potentially valence perception (i.e., how sound is emotionally perceived). Blue-tailed skinks (Emoia impar) altered both immediate behavior and their delayed risk assessment when human screaming was broadcast, but only in residential areas. By contrast, white-bellied copper-striped skinks (Emoia cyanura) only altered their delayed risk assessment when human stimuli were broadcast in residential areas. These results indicate that skinks respond differently to human vocalizations depending on their exposure to humans and based on species-specific behaviors. Our results suggest the importance of considering many variables when studying cognition in nature. The amount of human exposure and the acoustic cues contained in auditory stimuli may affect an individual's risk assessment and behavioral responses.","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"71 6","pages":"763-772"},"PeriodicalIF":2.0,"publicationDate":"2025-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12742395/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145850913","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 assessment of sexual displays in noise poses a common challenge for wildlife. Multimodal signals are hypothesized to be favored since they improve the accuracy of signal detection and discrimination in noise. We verified whether female treefrogs exhibit a heightened reliance on visual cues when acoustic cues are drowned out by the noise and whether increased call complexity can compensate for the attractiveness differences between unimodal and multimodal signals. Our results demonstrated that female treefrogs prefer longer courtship signals in the absence of noise. Meanwhile, increasing call complexity effectively mitigated the attractiveness difference between acoustic and visual/multimodal signals. However, female treefrogs did not shift their reliance to visual signals when masked by noise. Noise prolonged the duration required for females to make a mate choice in most cases and reduced female preferences for attractive signals regardless of whether the mating scene was unimodal or multimodal, which lends further the hypothesis of cross-sensory interference. We examined how female treefrogs weigh unimodal and multimodal courtship cues in the absence and presence of noise and offered distinct perspectives on the interplay of multi-sensory sexual displays in noise. This study enhanced our comprehension of noise interference in mating choice and established a novel, comprehensive scientific foundation for the prevention and control of multimodal sensory pollution.","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"71 6","pages":"683-691"},"PeriodicalIF":2.0,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12742384/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145850695","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}

Understanding whether sponges exhibit preferential growth regions and axial patterning is essential for elucidating the evolution of metazoan body plans. Here, we compared two body regions of the repent morph of Cladocroce caelum (Demospongiae): the proximal region, containing fully developed aquiferous system modules, and the distal region, hypothesized as the primary growth region. Our findings show that specimens predominantly grow from the distal region, where archaeocytes constitute the main cell type (mean 65.3%), whereas the proximal region features aquiferous system modules primarily composed of choanocytes (47%). To further explore molecular differences, we assembled a de novo reference transcriptome for C. caelum, recovering 99% of universal eukaryotic orthologous genes and 94% of metazoan orthologs. RNA-seq analysis revealed the expression of genes associated with the germline, stem cells, and developmental signaling pathways in both regions. However, we identified 11,421 differentially expressed genes (3,506 upregulated in the proximal region and 7,925 in the distal region). Notably, genes involved in the WNT, TGF-β, and MAPK pathways-key regulators of development and cell proliferation-were upregulated in the distal region. These findings provide morphological and molecular evidence of regional specialization in C. caelum, supporting the existence of a preferential growth region at the distal end. Our results suggest that despite the unique organization of the sponge body plan, some poriferans may possess specialized growth regions, akin to those in other metazoans.","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"71 6","pages":"745-762"},"PeriodicalIF":2.0,"publicationDate":"2025-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12742393/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145851328","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, the influence of historical geoclimatic events on the diversification of subsurface biota remains poorly understood. This study investigates the phylogeny and evolutionary history of under-recognized hypogean fishes in the Nemacheilidae family (HFN) in southwestern China, using mitogenome and nuclear gene sequencing. Our phylogeny supports the current genus-level classification but reveals conflicts between mitochondrial and nuclear gene topologies, suggesting past hybridization events. The ancestor of the HFN originated in eastern China-Korean Peninsula-Japanese Islands, north of northwest China-Mongolian Plateau, the Qinghai-Xizang (Tibetan) Plateau-Hengduan Mountains during the late Eocene (~36 million years ago [Mya]) and early Miocene (~16 Mya), and dispersed twice into the karst region of southwestern China. An ancient radiation event occurred from 22.44 Mya to 12.25 Mya. In situ diversification is the major speciation event, originating around 30 Mya and increasing sharply at ~11 Ma, with 3 peaks at ~7 Mya, ~3 Mya, and 1 Mya, and 2 valleys at ~5 Mya and ~2 Mya. Ancestral state reconstruction suggests at least 4 independent origins for the colorless, eye-blind, and troglobitic species morphs, as opposed to 2 events for the caudal adipose keel, and that these traits have undergone multiple reversals. These results highlight the role of geological processes and climatic events in the evolution of hypogean fishes and provide insights for conservation efforts, particularly in specialized cave habitats.","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"71 6","pages":"715-732"},"PeriodicalIF":2.0,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12742389/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145851234","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}

These chromosomal lineages differ morphologically and genetically in a manner that can be successfully discriminated, based on their morphology (95% of success) and molecular variation (99.9% of success), in the studied set of samples, and so considering these data this could potentially represent isolated evolutionary lineages or taxa. This situation is discussed in relation to the data available in previous studies in this and other geographical areas for this species. The new findings do not solve the problem of the Robertsonian polymorphism known to exist in this species, but it could perhaps suggest a new approach to solve it, suggesting a wide geographical comparison between the 2 taxa to confirm if they represent evolutionary isolated lineages or maintain a certain degree of hybridization.","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"71 6","pages":"733-744"},"PeriodicalIF":2.0,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12742394/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145851243","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}

Using an urban exploiter, the Eurasian tree sparrow (ETS; Passer montanus), we investigated how both sexes of urban and rural populations modulate twenty-two physiological markers of nutrition, body condition, oxidative stress, and antioxidative responses during pre-breeding stage. Our results showed that urban ETSs displayed distinct glucolipid metabolism compared to rural ETSs, characterized by higher levels of free fatty acids, β-hydroxybutyric acid, high-density lipoprotein (HDL), and total cholesterol, alongside lower levels of triglycerides, glucose (Glu), and fat content (FC). No significant differences were observed in other physiological markers. Additionally, both sexes of urban ETSs exhibited similar profiles across these markers, unlike rural populations where females showed higher Glu and total protein levels and lower HDL and FC levels than males. Our findings suggest that birds adjust their nutritional physiological markers in response to urbanization, likely due to dietary differences between urban and rural environments. Furthermore, sex differences in physiological markers of nutrition, body condition, oxidative stress, and antioxidant responses appear to diminish in urban settings.","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"71 6","pages":"703-714"},"PeriodicalIF":2.0,"publicationDate":"2025-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12742387/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145851382","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}

A remarkable example involving different predator species with complementary hunting skills is Lahille's bottlenose dolphins, Tursiops truncatus gephyreus foraging with net-casting human fishers to catch migratory mullet, Mugil liza. It remains unknown, however, to what extent dolphins coordinate their own actions when foraging with humans, and how intraspecific coordination impacts interspecific foraging success. Using drone-based tracking, we quantified dolphin group surfacing behaviors (diving synchrony, proximity, and heading angles between individuals) and tested the repeatability of these behavioral metrics across independent human-dolphin cooperative foraging interactions. We then quantified how the variance and consistency in these behaviors influenced the likelihood of fishers catching mullet. We found repeatable patterns in dolphin group proximity and heading angles across cooperative foraging interactions with fishers, and that fishers were more successful at catching mullet when dolphins approached them along different trajectories with consistent diving synchrony. These findings suggest that groups of dolphins can be, to some extent, coordinated when fishing with humans, thereby influencing the collective outcome of this cooperative foraging tactic. We consider hypotheses for the underlying mechanisms of synchrony and coordination within groups of dolphins and highlight solutions for overcoming the inherent challenges associated with quantifying collective foraging dynamics in natural settings.","PeriodicalId":50599,"journal":{"name":"Current Zoology","volume":"71 6","pages":"692-702"},"PeriodicalIF":2.0,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12742386/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145851259","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}
