For example, cats, dogs, and many other species have a preferred paw when handling food2. But why should humans and other animals have lateralized brains? Based on a large comparative approach1, it is likely that asymmetries serve several purposes. First, by specializing on one limb or one side of its sensory system, the contralateral hemisphere goes through life-long cycles of motor and perceptual learning, thereby increasing the speed of processing and motor efficacy, decreasing reaction time, and enhancing discrimination ability. Second, by having two complementary, specialized hemispheres, neural processes are computed in parallel, thereby reducing cognitive redundancy1. For example, the right hemisphere excels in processing threat-related stimuli, providing the left visual field an advantage in reacting to a predator approaching from the left3. Here, we report that two-thirds of cats prefer a leftward sleeping position, giving their left visual field and thus their right brain half a privileged view of approaching animals without being obstructed by their own body.

Adult corals rely on a vital nutritional exchange with their symbiotic algae (Symbiodiniaceae), but the dynamics of reliance from fertilization to recruitment are understudied. We investigated the physiological, metabolomic, and transcriptomic changes across 13 developmental stages of Montipora capitata, a coral in Hawai'i that inherits symbionts from parent to egg. We found that embryonic development depends on maternally provisioned mRNAs and lipids, with a rapid shift to symbiont-derived nutrition in late developmental stages. Symbiont density and photosynthesis peak in swimming larvae to fuel pelagic dispersal. By contrast, respiratory demand increases significantly during metamorphosis and settlement, reflecting this energy-intensive morphological reorganization. Symbiont proliferation is driven by symbiont ammonium assimilation in larval stages with little evidence of nitrogen metabolism in the coral host. As development progresses, the host enhances nitrogen sequestration, regulating symbiont populations, and ensuring the transfer of fixed carbon to support metamorphosis, with both metabolomic and transcriptomic indicators of increased carbohydrate availability. Although algal symbiont community composition remained stable, bacterial communities shifted with ontogeny, associated with holobiont metabolic reorganization. Our study reveals extensive metabolic changes during development with increasing reliance on symbiont nutrition. Metamorphosis and settlement emerge as critical periods of energetic vulnerability to projected climate scenarios that destabilize symbiosis. This highly detailed characterization of symbiotic nutritional exchange during sensitive early life stages provides essential knowledge for understanding and forecasting the function of nutritional symbioses and, specifically, coral survival and recruitment in a future of climate change.","PeriodicalId":11359,"journal":{"name":"Current Biology","volume":" ","pages":"2858-2871.e6"},"PeriodicalIF":8.1,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144180966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Buddhism and Taoism, the most popular religions in China, have significant cultural and spiritual associations with specific trees.4,5 Over the past two millennia, Buddhist and Taoist temples were widely constructed in the country, accompanied by intentional tree cultivation within temple grounds. This study examined the role of these religious cultures in conserving old trees within human-dominated landscapes and in facilitating the spread of religion-related species in China. We established a database encompassing 46,966 old trees from 5,125 Buddhist and 1,420 Taoist temples throughout China. Preserving old trees in religious temples was common in eastern China. The density of old trees in temples was thousands of times higher than outside temples, and tree age was also greater. There were 5,989 old trees from 61 threatened species (with eight species found exclusively in temples) preserved in temples, demonstrating crucial refuges for these species in human-dominated landscapes. The range of old trees of Buddhist species (tree species important to Buddhist culture) significantly exceeded that of non-Buddhist species. Some key Buddhist species have been introduced and cultivated in many Buddhist temples in areas far beyond their natural distribution, indicating a strong cultural influence on their spread. In summary, our findings demonstrated that religious grounds have provided refuges for old trees and facilitated the spread and protection of favored tree species in ancient China.","PeriodicalId":11359,"journal":{"name":"Current Biology","volume":" ","pages":"2994-3000.e3"},"PeriodicalIF":8.1,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144233510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the past five decades, increasing temperatures and land-use change in montane and subalpine elevations facilitated the productivity and expansion of competitive vegetation, termed as \"greening,\" with adverse effects on open grassland habitats. Although vegetation greening is well-documented through satellite observations, its impact on the populations and genomic integrity of affected species remains underexplored. Here, we address this challenge by integrating 40 years of remote sensing data with museum genomics and fieldwork to assess the impact of mountain greening on the genomic diversity of grassland plants in the southern Balkan peninsula. We sequenced the genomes of historical and modern populations of Ironwort, a plant of significant medicinal value, and demonstrate widespread genomic erosion across its populations. Our results show that, on average, 6% (0%-20%) of Ironwort's genome is affected by inbreeding accumulation over the past half century, indicating various degrees of population declines. Importantly, we show that genomic erosion is highly predictable by the normalized difference vegetation index (NDVI) rates of change. Our models suggest that faster increases in vegetation density are associated with higher population declines in this grassland species, revealing the negative impacts of increasing productivity in mountain ecosystems. By linking two independent and disparate monitoring indicators, we demonstrate the ability of remote sensing to predict the consequences of environmental change on temporal genomic change in mountain grassland species, with far-reaching implications for protecting natural resources in these fragile ecosystems.","PeriodicalId":11359,"journal":{"name":"Current Biology","volume":" ","pages":"2761-2770.e5"},"PeriodicalIF":8.1,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143984426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the molecular-genetic basis of the circadian clocks driving daily rhythms in terrestrial animals is well understood, the nature of the circatidal clocks driving tidal rhythms remains a mystery. Using in situ hybridization, we identified discrete clusters of ∼60 putative \"clock\" cells co-expressing canonical circadian clock genes across the protocerebrum of E. pulchra and P. hawaiensis brains. In field-collected, tidally rhythmic E. pulchra sampled under a light:dark (LD) cycle, the expression of period (per) and cryptochrome 2 (cry2) exhibited daily rhythms in particular cell groups, whereas timeless (tim) showed 12-h rhythms in others. In tidally rhythmic laboratory-reared P. hawaiensis, previously entrained to 12.4-h cycles of agitation under LD and sampled under continuous darkness, several cell groups (e.g., medioposterior cells) exhibited circadian expression of per and cry2. In contrast, dorsal-lateral cells in the protocerebrum exhibited robust ∼12-h, i.e., circatidal, rhythms of per and cry2, phased to the prior tidal agitation but not the prior LD. In P. hawaiensis exhibiting daily behavior under LD without tidal agitation, robust daily rhythms of per and cry2 expression were evident in medioposterior and other cells, whereas expression in dorsal-lateral cells was not rhythmic, underlining their essentially tidal periodicity. These results implicate canonical circadian molecules in circatidal timekeeping and reveal conserved brain networks as potential neural substrates for the generation of daily and tidal rhythms appropriate to intertidal habitats.","PeriodicalId":11359,"journal":{"name":"Current Biology","volume":" ","pages":"2802-2815.e5"},"PeriodicalIF":8.1,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143984964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, how wild animals maintain sleep homeostasis and how socio-ecological pressures interfere with their sleep remain understudied. Here, we investigated sleep homeostasis and the factors that influence sleep duration among wild Sumatran orangutans (Pongo abelii), leveraging a comprehensive long-term dataset of their behavior, sociality, and ecology. We quantified sleep in 53 adult individuals using the time that an individual spent in a sleeping nest-i.e., its sleep period-as an indicator of time spent sleeping. We found that, after shorter nighttime sleep periods, orangutans' next-day cumulative nap period duration was longer and that shorter nap periods were associated with a higher number of naps on the same day. We also found that orangutans had shorter sleep periods (night and day) when they associated with more conspecifics. Orangutans also had shorter nighttime sleep periods when they traveled farther the day before, and they had longer cumulative nap periods on days when (1) they ate fewer calories, (2) the ambient temperature was cooler, and (3) it rained. Our results suggest that multiple factors shape wild orangutans' sleep behavior and that orangutans compensate for lost sleep via daytime napping. This supports the hypothesis that social and ecological pressures interfere with sleep among wild animals and that they must balance the costs and benefits of sleep with those of other critical activities.","PeriodicalId":11359,"journal":{"name":"Current Biology","volume":" ","pages":""},"PeriodicalIF":8.1,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144505103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
