Researchers analyzed zinc isotopes in teeth and discovered that great white sharks make have contributed to the extinction of megalodon. Scientists investigated the diet of megalodon, the largest shark to have ever lived, using zinc isotopes. In a new study, researchers compared how high up the food chain megalodon and great white sharks feed, by analyzing the zinc stable isotope ratios in their teeth. They found that there was likely overlap in the prey of both species, and therefore, dietary competition with great white sharks may have contributed to the extinction of megalodon. Megatooth sharks like, Otodus megalodon, more commonly known as megalodon, lived between 23 and 3.6 million years ago in oceans around the globe and possibly reached as large as 20 meters (66 feet) in length. For comparison, the largest great white sharks today reach a total length of only six meters (20 feet). Many factors have been discussed to explain the gigantism and extinction of megalodon, with its diet and dietary competition often being thought of as key factors. In this study, researchers analyzed zinc stable isotope ratios in modern and fossil shark teeth from around the globe, including teeth of megalodon and modern and fossil great white sharks. This new method allows scientists to investigate an animal’s trophic level, which indicates how far up the food chain an animal feeds. Zinc stable isotope analysis of tooth enameloid, the highly mineralized part of teeth, is comparable to much more established nitrogen isotope analysis of tooth collagen, the organic tissue in tooth dentine, which is used to assess the degree of animal matter consumption. However, “on the timescales we investigate, collagen is not preserved, and traditional nitrogen isotope analysis is therefore not possible,” explains lead author Jeremy McCormack, a researcher at the Max Planck Institute for Evolutionary Anthropology and the Goethe-University Frankfurt. “Here, we demonstrate, for the first time, that diet-related zinc isotope signatures are preserved in the highly mineralized enameloid crown of fossil shark teeth,” adds Thomas Tütken, professor at the Johannes Gutenberg University’s Institute of Geosciences.

Subsequently, the researchers analyzed the zinc isotope ratios in megalodon teeth from the Early Pliocene and those in earlier megatooth sharks, Otodus chubutensis, from the Early Miocene as well as contemporaneous and modern great white sharks to investigate the impact these iconic species had on past ecosystems and each other. “Our results show, that both megalodon and its ancestor were indeed apex predators, feeding high up their respective food chains,” says Michael Griffiths, professor at the William Paterson University. “But what was truly remarkable is that zinc isotope values from Early Pliocene shark teeth from North Carolina, suggest largely overlapping trophic levels of early great white sharks with the much larger megalodon.” Lead author Jeremy McCormack isolating zinc from shark tooth samples by column chromatography in metal-free clean laboratory. Credit: © MPI for Evolutionary Anthropology Dietary Competition of Megalodon With Great White Sharks “These results likely imply at least some overlap in prey hunted by both shark species,” notes Kenshu Shimada, professor at DePaul University, Chicago. “While additional research is needed, our results appear to support the possibility for dietary competition of megalodon with Early Pliocene great white sharks.” New isotope methods such as zinc provide a unique window into the past. “Our research illustrates the feasibility of using zinc isotopes to investigate the diet and trophic ecology of extinct animals over millions of years, a method that can also be applied to other groups of fossil animals including our own ancestors,” concludes McCormack.

Blue button jellies, known by their scientific name Porpita, float on the ocean’s surface using a round disc, and drift where the current takes them.

Their findings were recently published in the journal PLOS Biology. There exist five major oceanic gyres — areas where numerous ocean currents converge — with the North Pacific Subtropical Gyre (NPSG) being the largest. This region, commonly referred to as the North Pacific “Garbage Patch”, is characterized by a high concentration of plastic waste due to the convergence of ocean currents. However, a variety of floating marine species, including jellyfish (cnidarians), snails, barnacles, and crustaceans, may also take advantage of these currents to navigate the open seas, though their precise habitats remain largely unknown.

The expedition’s route was planned using computer simulations of ocean surface currents to predict areas with high concentrations of marine debris. The team collected daily samples of floating life and waste in the eastern NPSG and found that sea creatures were more abundant inside the NPSG than on the periphery. The occurrence of plastic waste was positively correlated with the abundance of three groups of floating sea creatures: sea rafts (Velella sp), blue sea buttons (Porpita sp), and violet sea snails (Janthina sp). The violet snails Janthina construct floating bubble rafts by dipping their body into the air and trapping one bubble at a time, which they then wrap in mucus and stick to their float. Credit: Denis Riek, The Global Ocean Surface Ecosystem Alliance (GO-SEA) Field Guide (CC-BY 4.0) The same ocean currents that concentrate plastic waste at oceanic gyres may be vital to the life cycles of floating marine organisms, by bringing them together to feed and mate, the authors say. However, human activities could negatively impact these high-sea meeting grounds and the wildlife that depends on them. Helm adds, “The ‘garbage patch’ is more than just a garbage patch. It is an ecosystem, not because of the plastic, but in spite of it.” Reference: “High concentrations of floating neustonic life in the plastic-rich North Pacific Garbage Patch” by Fiona Chong, Matthew Spencer, Nikolai Maximenko, Jan Hafner, Andrew C.

A recent study has found that siblings affected by autism inherit a greater proportion of their genetic material from their father rather than their mother. New Research Suggests Fathers May Play a Greater Genetic Role in Autism Spectrum Disorder Researchers from Cold Spring Harbor Laboratory (CSHL) have recently revised the commonly held genetic assumptions about autism spectrum disorder (ASD). For many years, scientists believed that siblings diagnosed with ASD tended to inherit more genetic traits from their mother than their father. However, Associate Professor Ivan Iossifov and Professor Michael Wigler from CSHL have demonstrated that it could often be the father who has a more significant genetic contribution in numerous instances. Autism spectrum disorders cover a range of neurological and developmental conditions. They can affect how a person communicates, socializes, learns, and behaves. ASD may also manifest as repetitive behaviors or restricted interests. In the United States, it affects around one in 36 children. “There are children diagnosed with autism who are high functioning,” Iossifov says. “They have a completely productive life, although they have some minor troubles in social interactions, as most of us do. But also, there are children diagnosed with autism who never learn to speak, and they have definitely a difficult life.” For decades, Cold Spring Harbor Laboratory scientists and collaborators have invested millions of dollars into deciphering the genetic causes of autism spectrum disorder (ASD). Their efforts have produced useful insights for diagnosticians, therapists, and educators, helping to change the way people think about this common neurodevelopmental disorder. Now, they’ve taken their work another big step further, once again overturning popular assumptions about autism and its genetic origins. Credit: Cold Spring Harbor Laboratory Over the last two decades, CSHL scientists have led a multimillion-dollar effort to uncover the genetic origins of autism. They discovered thousands of genes that, when damaged, may cause a child to be born with ASD. But their work was not able to account for all cases of ASD. So Iossifov and Wigler set out to find the missing sources. The duo analyzed the genomes of over 6,000 volunteer families. They found that in families that have two or more children with ASD, the siblings shared more of their father’s genome. Meanwhile, in families where only one sibling had ASD, the children shared less of their father’s genome. While the discovery reveals a new potential source of ASD, it also poses a provocative question. Could other disorders play by the same genetic rules? Exploring Potential Mechanisms Behind Paternal Influence No one is sure how dad’s genome makes its mark on children with ASD. But Iossifov has a couple of interesting ideas. He thinks some fathers may carry protective mutations that fail to get passed on. Or fathers may pass down mutations that trigger the mother’s immune system to attack the developing embryo. Both theories offer hope for parents of children with ASD and other neurological disorders like schizophrenia. “Our future research is exciting,” Iossifov says. “If one of those theories or two of them prove to be true, then it opens different treatment strategies, which can, in the future, affect quite a lot of families.” In addition, this research offers helpful tools for educators and therapists. It may allow for earlier diagnoses and a better overall understanding of autism.
