Recent research[cm_tooltip_parse][/cm_tooltip_parse] reveals that clown anemonefish demonstrate cognitive abilities previously unrecognized, such as distinguishing species by counting the white bars on other anemonefish. Through experiments, it was found that these fish show varying levels of aggression based on the number of bars, suggesting a more complex social structure and cognitive capacity than previously understood. New research suggests that the fish may be counting vertical bars on intruders to determine their threat level, and to inform the social hierarchy governing their sea anemone colonies. We often think of fish as carefree swimmers in the ocean, reacting to the world around them without much forethought. However, new research from the Okinawa Institute of Science and Technology (OIST) suggests that our marine cousins may be more cognizant than we credit them for. By observing how a colony of clown anemonefish (Amphiprion ocellaris) – the species of the titular character in Finding Nemo – reacts to intruders in their sea anemone home, OIST researchers have found that the fish recognize different anemonefish species based on the number of white bars on their bodies. Clown anemonefish (Amphiprion ocellaris) photographed in the wild. Credit: Kina Hayashi “The frequency and duration of aggressive behaviors in clown anemonefish was highest toward fish with three bars like themselves,” explains Dr. Kina Hayashi from the Marine Eco-Evo-Devo Unit at OIST, first author on the paper published in the Journal of Experimental Biology, “while they were lower with fish with one or two bars, and lowest toward those without vertical bars, which suggests that they are able to count the number of bars in order to recognize the species of the intruder.” The clown anemonefish is normally a gracious host, allowing many different species to visit their sea anemone. However, should a member of their own species, and which is not part of the colony, enter their home, the largest fish of the colony, referred to as the alpha fish, will aggressively bite and chase out the intruder. Figure showing the aggressive behavior of Amphiprion ocellaris, or clown anemonefish, in response to different species of anemonefish, both live and models. Credit: Kina Hayashi Behavioral Experiments and Findings To figure out how these fish determine the species of their visitors, Dr. Hayashi and colleagues conducted two sets of experiments with immature clown anemonefish raised in the lab. In the first set, they placed different species of anemonefish, with different numbers of white bars, in small cases inside a tank with a clown anemonefish colony and observed how often and for how long the fish would aggressively stare at and circle the case. In the second set, the researchers presented a colony of clown anemonefish with different plastic discs painted with true-to-life anemonefish coloration and measured the level of aggression towards these models.

Credit: Kina Hayashi The clown anemonefish displayed the most aggressive behavior towards the intruders with three bars like themselves. Fish and plastic models with two bars were attacked slightly less frequently, while the ones with one or zero bars received the least aggressive response. Previous studies have shown that clown anemonefish react much stronger to models with vertical rather than horizontal bars, suggesting that the amount of white color or the general presence of white bars is not the deciding factor. Combined with the observation that the plastic discs, which have no species defining traits other than the vertical bars, received the same response as the live fish, lead the researchers to suggest that the fish appear to be counting the number of vertical white bars to inform their level of aggression toward intruders. The plastic models used to measure the clown anemonefish’s aggressive behavior. Credit: Kina Hayashi Social Structure and Ecological Implications “The researchers also discovered a strict hierarchy in the clown anemonefish colonies that determines which fish attack the intruder. In the wild, a colony typically consists of one alpha female, one beta male, and several gamma juveniles. The social position within the colony is determined by very slight differences in size. Anemonefish get their third and final stripe when they grow large enough, which is why the current alpha uses harsh methods to uphold the status quo, including chasing out colony members if they grow too large. Though the researchers used immature fish that have yet to metamorphize into males or females, they still observed the same size-based hierarchy, with the largest juvenile taking on the role of alpha and leading the charge against the intruder. “Anemonefish are interesting to study because of their unique, symbiotic relationship with sea anemones. But what this study shows is that there is much we don’t know about life in the marine ecosystems in general,” says Dr. Hayashi. The study is a sobering reminder to preserve the fragile coral reefs that fish like the anemonefish inhabit. If the clown anemonefish, which is popular both as a pet and in the media, can surprise us with their abilities to count bars and maintain strict social hierarchies, then it begs the question of how many remarkable animals and animal behaviors have yet to be discovered in these ecosystems under threat.

A research study from the University of Southampton has unveiled that corals feed on microscopic algae living within their cells, accessing a nutrient source previously thought unavailable. This discovery answers a long-standing mystery known as Darwin’s Paradox of Coral Reefs, explaining how corals flourish in nutrient-poor waters. Corals sustain growth in nutrient-poor waters by farming and consuming their symbiotic algae, but climate change may disrupt this process, threatening coral reef survival. A new study led by the University of Southampton in the UK has uncovered why coral reefs flourish in waters that appear to be deficient in nutrients, a phenomenon that has fascinated scientists since Charles Darwin. The research shows that corals farm and feed on their photosynthetic symbionts – microscopic algae that live inside their cells. This vegetarian diet allows the corals to tap into a large pool of nutrients that was previously considered unavailable to them. Effectively, they are eating some of their symbiont algae to get the nutrition they need to survive. Professor Jörg Wiedenmann, Head of the Coral Reef Laboratory at the University of Southampton, who led the study comments: “The question as to why coral reefs thrive in parts of the oceans that are poor in nutrients is known as Darwin’s Paradox of Coral Reefs and has inspired the discovery of several important processes that can help to explain this phenomenon. We can now add the missing piece of the puzzle and help to solve the long-running mystery.” Reef corals provide home and feeding grounds for many organisms. Credit: Wiedenmann / D’Angelo / University of Southampton He continues: “When Charles Darwin set sail on the HMS Beagle, he considered himself a geologist and during his voyage through tropical seas, quickly became interested in where and why coral reefs are formed. Darwin correctly predicted how the subsidence of the Earth’s crust and the steady upward growth of corals interact to form vast reef structures. However, the biological mechanisms behind this vigorous growth remained unstudied.” Surviving Together Stony corals are soft-bodied creatures that may look like plants to some, but are in fact animals. These organisms are made up of many individual polyps that live together as a colony and secret limestone skeletons which form the three-dimensional framework we know as ‘reefs’. Coral reefs are important underwater ecosystems that benefit many human communities. They provide a home and feeding ground for countless organisms, sustaining about 25 percent of global ocean biodiversity. Thereby, they deliver food and income to about half a billion people on Earth. Unicellular symbiont algae of a reef coral showing growth by cell division. Credit: Wiedenmann / D’Angelo / University of Southampton The coral animals are dependent on a ‘symbiosis’, a mutually beneficial relationship with microscopic algae that live inside their cells. The photosynthetic algae produce large amounts of carbon-rich compounds, such as sugars, which they transfer to the host coral for energy generation. The symbiont algae are also very efficient in taking up dissolved inorganic nutrients from seawater, such as nitrate and phosphate. Even in nutrient-poor oceans, these compounds can be found in considerable amounts as excretion products of organisms, such as sponges, that live close by. They can also be transferred to reefs by ocean currents. What the Scientists Found In contrast to their symbionts, the coral host cannot absorb or use dissolved inorganic nutrients directly and, until now, it was unclear how these nutrients could fuel the growth of coral. However, the mechanism by which these essential growth nutrients are transferred to the coral animals has been identified by scientists from the University of Southampton, working with a team of collaborators including Lancaster University in the UK, Tel Aviv University, and the University of Jerusalem in Israel. Their findings are published in the journal Nature. Experimental aquarium of the Coral Reef Laboratory at the University of Southampton. Credit: Wiedenmann / D’Angelo / University of Southampton By performing a series of long-term experiments at the University of Southampton’s Coral Reef Laboratory, the scientists demonstrated that corals actually digest some of their symbiont population to access the nitrogen and phosphorus that symbionts absorb from the water. Where there are sufficient dissolved inorganic nutrients in the water, this mechanism allows corals to grow quickly, even if they do not receive any additional food. Results from fieldwork in remote coral reef atolls in the Indian Ocean support the lab findings, demonstrating that this mechanism boosts coral growth in the wild at the ecosystem level. Dr Cecilia D’Angelo, Associate Professor of Coral Biology at Southampton and one of the lead authors, comments: “Over the many years during which we propagated symbiotic corals in our experimental aquarium system, we had observed that they grew very well even when they were not fed. It could not be explained by the current state of knowledge how nutrients were exchanged by the two partners of the symbiosis, so we figured that we were missing a big piece of the picture and started to analyze the process systematically.” Seabirds introduce nutrients in coral reefs in the Indian Ocean. Credit: Nick Graham, Lancaster University Dr Loreto Mardones-Velozo, a researcher in the Coral Reef Laboratory who conducted key experiments, adds: “One would expect that animals die or stop growing if they don’t eat. However, the corals looked perfectly happy and grew rapidly if we kept them in water with elevated levels of dissolved inorganic nutrients.” The Science Behind the Findings The researchers used a specifically labeled chemical compound to track the movement of the essential nutrient nitrogen between the partners of the symbiosis. Nitrogen in the chemical form used in the experiments can be only integrated in their cells by the symbionts, but not the coral host. Bastian Hambach, Manager of the Stable Isotope Mass Spectrometry Laboratory at the University of Southampton, explains: “We used isotopic labeling to ‘spike’ the nutrients supplied to the corals with nitrogen atoms that were heavier than normal. These isotopes allowed us to trace the coral’s use of the nutrients using ultrasensitive detection methods.” Dr. Cecilia D’Angelo propagating corals in the Coral Reef Laboratory at the University of Southampton. Credit: Wiedenmann / D’Angelo / University of Southampton Professor Paul Wilson, paleoceanographer at the University of Southampton expands: “With this technique, we could unambiguously demonstrate that the nitrogen atoms that sustained the growth of the coral tissue were derived from the dissolved inorganic nutrients that were fed to their symbionts in the experiment.” Professor Jörg Wiedenmann of the University of Southampton adds: “We used 10 different coral species to quantify how the symbiont population grew along with their hosts. Using mathematical models of the symbiont growth, we could show that the corals digest the excess part of their symbiont population to harvest nutrients for their growth. Our data suggest that most symbiotic corals can supplement their nutrition through such a ‘vegetarian diet’.” The scientists also analyzed corals growing around islands in the Indian Ocean, some with seabirds on them and some without, to show that corals have the potential to farm and feed on their symbionts in the wild. Growth of the experimental coral Stylophora pistillata. Credit: Mardones-Velozo / D’Angelo / Wiedenmann / University of Southampton Professor Nick Graham, Marine Ecologist from Lancaster University, explains: “The reefs around some of these islands are supplied with substantial amounts of nutrients that come from ‘guano’, the excrements of the seabirds nesting on the islands. On other islands, the seabird colonies have been decimated by invasive rats. Accordingly, the associated reefs receive less nutrients. We measured the growth of staghorn coral colonies around islands with and without dense seabird populations and found that growth was more than twice as fast on reefs that were supplied with seabird nutrients. “We calculate that about half of the nitrogen molecules in the tissue of the coral animals from islands with seabirds can be traced back to uptake by the symbionts and the subsequent translocation to the host.” Scientist monitoring coral growth on Indian Ocean Reefs to study the effect of seabird nutrients. Credit: Nick Graham, Lancaster University Global Warming and the Future Excessive nutrient enrichment, often caused by human activities, can damage corals and represents a growing threat in many reefs. However, some coral reefs might receive less nutrients in the future as global warming may cut them off from some of their natural supply routes. Dr D’Angelo from the University of Southampton explains: “Warming surface waters are less likely to receive nutrients from deeper water layers. The reduced water productivity can result in less nutrients for the symbionts and in turn less food for the coral animals.” The scientists’ new findings suggest that while coral animals may endure brief periods of starvation by feeding off their symbionts, some coral reefs might be at risk of starvation in response to more prolonged nutrient depletion brought on by global warming in some areas.

Showing gene expression patterns. Credit: DOI: 10.1038/s41586-023-00000-0 Scientists reveal unprecedented insights into human limb development, including the many intricate processes that govern their formation. Human fingers and toes do not grow outward; instead, they form from within a larger foundational bud, as intervening cells recede to reveal the digits beneath. This is among many processes captured for the first time as scientists unveil a spatial cell atlas of the entire developing human limb, resolved in space and time. Innovative Research Collaboration Researchers at the Wellcome Sanger Institute, Sun Yat-sen University, EMBL’s European Bioinformatics Institute, and collaborators applied cutting-edge single-cell and spatial technologies to create an atlas characterizing the cellular landscape of the early human limb, pinpointing the exact location of cells. This study is part of the international Human Cell Atlas initiative to map every cell type in the human body,[1] to transform understanding of health and disease. Publication and Applications The atlas, published today (December 6) in the journal Nature, provides an openly available resource that captures the intricate processes governing the limbs’ rapid development during the early stages of limb formation.[2] The atlas also uncovers new links between developmental cells and some congenital limb syndromes, such as short fingers and extra digits. Understanding Limb Formation Limbs are known to initially emerge as undifferentiated cell pouches on the sides of the body, without a specific shape or function. However, after 8 weeks of development, they are well differentiated, anatomically complex, and immediately recognizable as limbs, complete with fingers and toes. This requires a very rapid and precise orchestration of cells. Any small disturbances to this process can have a downstream effect, which is why variations in the limbs are among the most frequently reported syndromes at birth, affecting approximately one in 500 births globally.[3] Bridging Human and Animal Models While limb development has been extensively studied in mouse and chick models, the extent to which they mirror the human situation remained unclear. However, advances in technology now enable researchers to explore the early stages of human limb formation. In this new study, scientists from the Wellcome Sanger Institute, Sun Yat-sen University, and their collaborators analyzed tissues between 5 and 9 weeks of development. This allowed them to trace specific gene expression programs, activated at certain times and in specific areas, which shape the forming limbs. Special staining of the tissue revealed clearly how cell populations differentially arrange themselves into patterns of the forming digits. Video depicts gene expression clusters during limb development through spatial transcriptomic profiles and in situ staining of the tissue: This video shows the dynamic gene expression patterns of IRX1, SOX9 and MSX1, critical genes involved in limb formation. Their distinct distribution ensures the ‘chiseling’ process takes place. IRX1, crucial for digit formation, and SOX9, essential for skeletal development, converge into five distinct lengths within the developing limb, while MSX1, associated with undifferentiated cells, occupies the interdigital spaces between these clusters. At approximately week seven of development, molecules responsible for interdigital cell death are activated, leading to the elimination of cells in the intervening spaces. This orchestrated cell death finally unveils the well-defined shapes of fingers or toes. Credit: DOI: 10.1038/s41586-023-00000-0 Gene Patterns and Limb Syndromes As part of the study, researchers demonstrated that certain gene patterns have implications for how the hands and feet form, identifying certain genes, which when disrupted, are associated with specific limb syndromes like brachydactyly — short fingers — and polysyndactyly — extra fingers or toes. The team was also able to confirm that many aspects of limb development are shared between humans and mice. Overall, these findings not only provide an in-depth characterization of limb development in humans but also critical insights that could impact the diagnosis and treatment of congenital limb syndromes. Expert Insights Professor Hongbo Zhang, senior author of the study from Sun Yat-sen University, Guangzhou, said: “Decades of studying model organisms established the basis for our understanding of vertebrate limb development. However, characterizing this in humans has been elusive until now, and we couldn’t assume the relevance of mouse models for human development. What we reveal is a highly complex and precisely regulated process. It is like watching a sculptor at work, chiseling away at a block of marble to reveal a masterpiece. In this case, nature is the sculptor, and the result is the incredible complexity of our fingers and toes.” Dr. Sarah Teichmann, senior author of the study from the Wellcome Sanger Institute, and co-founder of the Human Cell Atlas, said: “For the first time, we have been able to capture the remarkable process of limb development down to single cell resolution in space and time. Our work in the Human Cell Atlas is deepening our understanding of how anatomically complex structures form, helping us uncover the genetic and cellular processes behind healthy human development, with many implications for research and healthcare. For instance, we discovered novel roles of key genes MSC and PITX1 that may regulate muscle stem cells. This could offer potential for treating muscle-related disorders or injuries.” Notes This study is part of the Human Cell Atlas (HCA), an international collaborative consortium which is creating comprehensive reference maps of all human cells—the fundamental units of life—as a basis for understanding human health and for diagnosing, monitoring, and treating disease. The HCA is likely to impact every aspect of biology and medicine, propelling translational discoveries and applications and ultimately leading to a new era of precision medicine.The HCA was co-founded in 2016 by Dr. Sarah Teichmann at the Wellcome Sanger Institute (UK) and Dr. Aviv Regev, then at the Broad Institute of MIT and Harvard (USA). A truly global initiative, there are now more than 3,100 HCA members, from 98 countries around the world. https://www.humancellatlas.org The researchers analyzed human embryonic limb tissues between weeks 5 to 9 post-conception, provided by Addenbrooke’s Hospital Cambridge, United Kingdom and the Women and Children’s Medical Centre, Guangzhou, China.
