Predator-prey interactions reshaped ocean life, adding a fourth evolutionary phase to the fossil record’s three-fauna model. Evolutionary arms races between marine animals overhauled ocean ecosystems on scales similar to the mass extinctions triggered by global disasters, a new study shows. Scientists at Umeå University in Sweden and the Florida Museum of Natural History used paleontological databases to build a multilayered computer model of the history of marine life over the last 500 million years. Their analysis of the fossil record closely echoed a seminal 1981 study by paleontologist J. John Sepkoski – with one key difference. Sepkoski’s ground-breaking statistical work showed abrupt ocean-wide changes in biodiversity about 490 and 250 million years ago, corresponding to two mass extinction events. These events divided marine life into what he called “three great evolutionary faunas,” each dominated by a unique set of animals. But the new model reveals a fourth. The fierce fight for survival that played out between predatory marine animals and their prey about 250 to 66 million years ago may have been an equally powerful force, reshaping ocean diversity into what we see today. This third grand transition was much more gradual than its predecessors and driven by organisms, rather than external processes. A seminal 1981 study organized the history of ocean life into three hierarchies, with certain animals reigning the seas during each time periods. Two mass extinctions cleared the way for new groups to flourish and dominate. But a new study provides evidence that the rise of marine predators was an equally powerful transition, resulting in a fourth hierarchy of marine life. Credit: Jeff Gage/Florida Museum of Natural History Biology, Not Catastrophe, Reshaped Ocean Life “What we learned is that not all major shifts in animal life have been related to mass extinction events,” said study lead author Alexis Rojas, who earned his Ph.D. at the University of Florida. Rojas is now a postdoctoral researcher at the Integrated Science Lab, a hub dedicated to interdisciplinary research at Umeå University. Many scientists have long held the view that external factors such as volcanic activity, asteroid impacts or changes in climate are the primary drivers of major shifts in the Earth’s biosphere, said study co-author Michal Kowalewski, Rojas’ doctoral adviser and the Florida Museum Thompson Chair of Invertebrate Paleontology. “The fossil record tells us that some of the key transitions in the history of life were rapid changes triggered by abrupt external factors. But this study shows that some of those major transitions were more gradual and may have been driven by biological interactions between organisms,” he said. Beginning about 150 million years ago, marine predators such as fish, snails, and crustaceans quickly diversified, dominating the sea. Their prey adapted by hiding, becoming more mobile or amping up their external defenses. This phenomenon, known as the Mesozoic Marine Revolution, produced the ocean life we see today and was likely as powerful as sudden mass extinctions in redefining what lived where. Credit: Jeff Gage/Florida Museum of Natural History Sepkoski’s Vision: Simplifying the Complexity of the Fossil Record One reason Sepkoski’s work was so revolutionary was that he took a mathematical approach to a practical problem: The fossil record is too big and complex for one person to be able to discern life’s underlying patterns by looking at specimens alone. “When its components are examined individually or in small groups, the complexity of their form, function, interaction, and history often seems overwhelming, and almost infinite,” he wrote in the introduction to his 1981 study. Organizing these components into a hierarchy of systems, he argued, presented a more complete view. Sepkoski’s modeling divided 500 million years of ocean life into three great dynasties, each separated by a mass extinction that cleared the way for new groups to flourish and dominate. After the reign of trilobites, clamlike animals known as brachiopods and certain ancient corals and ammonites rose to prominence. After the cataclysmic end-Permian extinction, sometimes known as the “Great Dying,” they were in turn replaced by snails, clams, crustaceans, modern corals, and various kinds of bony fishes. Now extinct, early arthropods known as trilobites appeared at least 520 million years ago and existed for nearly 300 million years. They vanished during the mass extinction event that marked the end of the Permian about 250 million years ago, the largest known die-off in the history of Earth. Credit: Florida Museum photo by Jeff Gage Sepkoski’s hypothesis fundamentally changed how scientists thought about the history of life, Kowalewski said. It offered an organized way of understanding the history of marine ecosystems – the overarching storyline and plot twists. But as our knowledge of the fossil record grows, so does Sepkoski’s dilemma of how to analyze such vast and complex information, said Kowalewski. “With millions of fossil specimens now documented, there is simply no feasible way for our brains to process such massive archives of paleontological data,” he said. “Fortunately, analytical methods continue to improve, giving us better ways to extract and examine information hidden inside these immensely complex data.” A Modern Lens on Ancient Life Rojas took on this challenge by using the latest advancements in data modeling. Specifically, he was interested in using complex network tools to create a better representation of the fossil record. Unlike other approaches in paleobiology, complex networks use a linked structure of nodes representing physical and abstract variables to uncover underlying patterns in a given system. Network approaches can be applied to social phenomena – for example, showing a Facebook user’s patterns of interactions with friends on the platform – but they can also be applied to complex natural systems. Like Sepkoski, Rojas is a classically trained paleontologist looking for a fresh perspective on the fossil record. The gold lines on this brachiopod, a clamlike animal, are pyrite deposits. Once widespread, brachiopods comprise their own unique phylum and still exist today. They ruled the seas before mollusks rose to dominance. Credit: Florida Museum photo by Jeff Gage “There are many processes happening at the same time at multiple scales: in your neighborhood, your country, and across the entire planet. Now imagine the processes that occur in one day, one year, or 500 years. What we are doing is trying to understand all these things across time,” he said. A simple network might consist of a single layer – all records of animal life and where they lived. But Rojas and his colleagues’ network incorporates different intervals of time as individual layers, a feature lacking in previous research on macroevolution. The result is what Rojas described as a new, abstracted fossil record, a complement to the physical fossil record represented by the specimens in museum collections. After death, ammonites would commonly float due to trapped gas in their shells. Collected by ocean currents, they often washed up and fossilized in groups, like this mass of Deshayesites deshayesi. Credit: Florida Museum photo by Jeff Gage “It’s important because the questions we are asking, the processes we are studying, occur at different scales in time and space,” Rojas said. “We’ve taken some steps back so we can look at the entire fossil record. By doing that, we can explore all sorts of questions.” Think of it like navigating a Google Earth that represents the oceans over the last 500 million years. When and where would you go? “Our interactive map of marine life shows smaller groups of animals and their interactions within each evolutionary fauna,” Rojas said. “At the most basic levels, this map shows ocean regions with particular animals. The building blocks of our study are the individual animals themselves.” The Mesozoic Marine Revolution: A Gradual Overhaul This complex network shows what Sepkoski’s model could not capture: a gradual transition in ocean life coincident with the Mesozoic Marine Revolution, which began about 150 million years ago. First hypothesized in the 1970s, this revolution was caused by the rapid increase of marine predators such as bony fish, crustaceans and snails, which have dominated oceans ever since. Their proliferation drove prey to become more mobile, hide beneath the ocean floor or enhance their defenses by thickening their armor, developing spines, or improving their ability to regenerate body parts. Where Sepkoski’s model showed three major groups of marine life, or evolutionary faunas, this study shows four, splitting the third and most recent group into two. This last transition was likely driven by organisms themselves, rather than external processes. Credit: Figure courtesy of Alexis Rojas Sepkoski knew about the Mesozoic Marine Revolution, but his model, limited by the methods and data available at the time, was unable to delineate the ocean ecosystems preceding and following this gradual transition. The study by Rojas and his colleagues demonstrates that both physical and biological processes play key roles in shaping ocean life at the highest levels. “We are integrating the two hypotheses – the Mesozoic Marine Revolution and the three great evolutionary faunas into a single story,” Rojas said. “Instead of three phases of life, the model shows four.” Reference: “A multiscale view of the Phanerozoic fossil record reveals the three major biotic transitions” by Alexis Rojas, Joaquin Calatayud, Michał Kowalewski, Magnus Neuman and Martin Rosvall, 8 March 2021, Communications Biology. DOI: 10.1038/s42003-021-01805-y Joaquin Calatayud, Magnus Neuman and Martin Rosvall of Umeå University also co-authored the study. The team published its results in Communications Biology. Support for the research was provided by the Olle Engkvist Byggmästare Foundation, the Carl Trygger Foundation and the Swedish Research Council. Researchers at the University of Florida have utilized CRISPR/Cas9 to modify the leaf angle of sugarcane, significantly enhancing its sunlight capture and biomass yield. This breakthrough in editing the complex, polyploid genome of sugarcane marks a major advancement in crop improvement and biofuel production. Researchers optimized sugarcane’s leaf angle using CRISPR gene editing, enhancing its sunlight absorption. Sugarcane ranks as the top crop globally in terms of biomass yield, contributing to 80 percent of sugar and 40 percent of biofuel production around the world. Its substantial size and optimal utilization of water and light position it as an ideal source for generating innovative renewable bioproducts and biofuels. However, as a hybrid of Saccharum officinarum and Saccharum spontaneum, sugarcane has the most complex genome of all crops. This complexity means that improving sugarcane through conventional breeding is challenging. Because of this, researchers turn to gene editing tools, such as the CRISPR/Cas9 system to precisely target the sugarcane genome for improvement.

Credit: Charles Keato Innovative Research for Crop Improvement In their new paper, published in Plant Biotechnology Journal, a team of researchers from the University of Florida at the Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) has leveraged this genetic complexity to their advantage to use the CRISPR/Cas9 system to fine-tune leaf angle in sugarcane. These genetic tweaks allowed the sugarcane to capture more sunlight, which in turn increased the amount of biomass produced. This work supports the DOE-funded CABBI Bioenergy Research Center’s “plants as factories” approach and the primary goal of its Feedstock Production research — to synthesize biofuels, bioproducts, and high-value molecules directly in the stems of plants such as sugarcane. The sugarcane genome’s complexity is due in part to its high levels of redundancy: It possesses many copies of each gene. The phenotype that a sugarcane plant displays, therefore, typically depends on the cumulative expression of the multiple copies of a certain gene. The CRISPR/Cas9 system is perfect for this task because it can be designed to edit a few or many copies of a gene at once. Baskaran Kannan evaluating gene-edited sugarcane in the field. Credit: Uzair Khan This study focused on LIGULELESS1, or LG1, a gene that plays a major role in determining leaf angle in sugarcane. Leaf angle, in turn, determines how much light can be captured by the plant, which is critical for biomass production. Since sugarcane’s highly redundant genome contains 40 copies of LG1, the researchers were able to fine-tune the leaf angle by editing different numbers of copies of this gene, resulting in slightly different leaf angles depending on how many copies of LG1 were edited. “In some of the LG1 edited sugarcanes, we just mutated a few of the copies,” said Fredy Altpeter, research team lead and Professor of Agronomy at the University of Florida. “And in doing so, we were able to tailor the leaf architecture until we found the optimal angle that resulted in increased biomass yield.” Field Trial Results and Future Implications When the scientists grew sugarcane in field trials, they found that the upright leaf phenotypes allowed more light to penetrate the canopy, which resulted in increased biomass yield. One sugarcane line in particular, which contained edits in ~12% of the LG1 copies and showed a 56% decrease in leaf inclination angle, had an 18% increase in dry biomass yield. By optimizing sugarcane to capture more light, these gene edits increase biomass yield without having to add more fertilizer to the fields. In addition to that, building a stronger understanding of complex genetics and genome editing helps researchers work toward refined approaches for crop improvement. “This is the first peer-reviewed publication describing a field trial of CRISPR-edited sugarcane,” Altpeter said. “And this work also shows unique opportunities for the editing of polyploid crop genomes, where researchers can fine-tune a specific trait.” Reference: “The extent of multiallelic, co-editing of LIGULELESS1 in highly polyploid sugarcane tunes leaf inclination angle and enables selection of the ideotype for biomass yield” by Eleanor J.

Corals display glowing colors (fluorescence). Credit: Tel Aviv University Researchers have proved for the first time that corals’ fluorescent colors are intended to attract prey. For the first time, a recent study from Tel Aviv University, in association with the Steinhardt Museum of Natural History and the Interuniversity Institute for Marine Sciences in Eilat, has established that the magical phenomenon in deep reefs where corals exhibit glowing colors (fluorescence) is intended to serve as a mechanism for luring prey. The research demonstrates that the marine creatures that corals feed on are drawn to fluorescent colors. Professor Yossi Loya from the School of Zoology and the Steinhardt Museum of Natural History at Tel Aviv University supervised the research, which was led by Dr. Or Ben-Zvi, Yoav Lindemann, and Dr. Gal Eyal. Fluorescence as a Prey-Attracting Strategy According to the researchers, the ability of aquatic organisms to glow has long attracted both scientists and those who love nature. The biological role of the phenomena, which occurs often in corals that produce reefs, has been fiercely disputed. A variety of possibilities have been explored over the years, including: Does this phenomenon defend against radiation? improve photosynthesis? an antioxidant activity? According to the most recent research, coral fluorescence actually serves as a lure for prey. In the study, the researchers put their hypothesis to the test; to this end, they first sought to determine whether plankton (small organisms that drift in the sea along with the current) are attracted to fluorescence, both in the laboratory and at sea. Then, in the lab, the researchers quantified the predatory capabilities of mesophotic corals (corals that live between the shallow coral reef area and the deep, completely dark zone of the ocean), which exhibit different fluorescent appearances. Plankton Attraction In order to test the planktons’ potential attraction to fluorescence, the researchers used, inter alia, the crustacean Artemia salina, which is used in many experiments as well as for food for corals. The researchers noted that when the crustaceans were given a choice between a green or orange fluorescent target versus a clear “control” target, they showed a significant preference for the fluorescent target. Moreover, when the crustaceans were given a choice between two clear targets, their choices were observed to be randomly distributed in the experimental setup. In all of the laboratory experiments, the crustaceans vastly exhibited a preferred attraction toward a fluorescent signal. Similar results were presented when using a native crustacean from the Red Sea. However, unlike the crustaceans, fish that are not considered coral prey did not exhibit these trends, and rather avoided the fluorescent targets in general and the orange targets in particular. A scientist obtaining data for the study. Credit: Tel Aviv University In the second phase of the study, the experiment was carried out in the corals’ natural habitat, about 40 meters deep in the sea, where the fluorescent traps (both green and orange) attracted twice as many plankton as the clear trap. Dr. Or Ben-Zvi says, “We conducted an experiment in the depths of the sea in order to examine the possible attraction of diverse and natural collections of plankton to fluorescence, under the natural currents and light conditions that exist in deep water. Since fluorescence is ‘activated’ principally by blue light (the light of the depths of the sea), at these depths the fluorescence is naturally illuminated, and the data that emerged from the experiment were unequivocal, similar to the laboratory experiment.” Predation Rates Linked to Fluorescent Coloration in Corals In the last part of the study, the researchers examined the predation rates of mesophotic corals that were collected at 45-meter (148-foot) depth in the Gulf of Eilat and found that corals that displayed green fluorescence enjoyed predation rates that were 25 percent higher than corals exhibiting yellow fluorescence. Professor Loya: “Many corals display a fluorescent color pattern that highlights their mouths or tentacle tips, a fact that supports the idea that fluorescence, like bioluminescence (the production of light by a chemical reaction), acts as a mechanism to attract prey. The study proves that the glowing and colorful appearance of corals can act as a lure to attract swimming plankton to ground-dwelling predators, such as corals, and especially in habitats where corals require other energy sources in addition or as a substitute for photosynthesis (sugar production by symbiotic algae inside the coral tissue using light energy).” Dr. Ben-Zvi concludes: “Despite the gaps in the existing knowledge regarding the visual perception of fluorescence signals by plankton, the current study presents experimental evidence for the prey-luring role of fluorescence in corals. We suggest that this hypothesis, which we term the ‘light trap hypothesis’, may also apply to other fluorescent organisms in the sea, and that this phenomenon may play a greater role in marine ecosystems than previously thought.” Reference: “Coral fluorescence: a prey-lure in deep habitats” by Or Ben-Zvi, Yoav Lindemann, Gal Eyal, and Yossi Loya, 2 June 2022, Communications Biology.
