Biju A study reveals unique breeding behaviors in the Andamanese Charles Darwin’s frog, including upside-down egg-laying and intense male competition. The species faces habitat challenges, breeding in unnatural sites like trash, underscoring urgent conservation needs. Researchers from the University of Delhi and Zoological Survey of India, Harvard University, and the University of Minnesota have discovered a unique breeding behavior in a species of frog endemic to the Andaman Islands of India. In a new study published in the Harvard Museum of Comparative Zoology’s journal Breviora, the scientists describe the frog’s unique combination of reproductive behaviors. The Andamanese Charles Darwin’s frog, Minervarya charlesdarwini, belongs to the family Dicroglossidae, a large radiation of Asian frogs that comprises over 220 species. Charles Darwin’s frogs naturally breed as well as deposit terrestrial eggs above the water surface on the inner walls of water-filled tree cavities or root buttresses. Hatchlings then drop into the water below and complete their development through a free-swimming tadpole stage. Distinctive Mating Postures and Reproductive Traits The posture of the mating pair at the time of egg-laying also makes Charles Darwin’s frog unique: the pair orient themselves in a vertical, upside-down posture on the tree cavity walls with their bodies completely out of the water.

Gokulakrishnan “Upside-down spawning is the most remarkable behavior in this frog. No other frog is known to lay terrestrial eggs inside tree holes in an upside-down position. This discovery is fundamental for understanding how the species interacts with its environments and which habitats are essential for its survival. Such specialized traits also yield insights into the evolution of reproductive modes and behaviors among anuran amphibians,” said Professor S. D. Biju of the University of Delhi, who led the study and is currently a Fellow at the Harvard Radcliffe Institute and an associate of Harvard’s Museum of Comparative Zoology. Aggressive Mating Dynamics and Territorial Fights The uniqueness of this frog does not end there. Male frogs produce complex advertisement calls comprising three different call types to attract females. They also make an aggressive call. When aggressive vocalizations fail to ward off competing males, physical combat begins. These fights include kicking and boxing using hands and legs, and biting of body parts or even the entire head. Males compete aggressively to mate with females. If a male successfully mounts a female, nearby unpaired males may physically fight with the amplectant pair. They may even try to insert their head between the bodies of the pair from the back side to separate them. The defending male often kicks the intruding males with his hind legs. Simultaneously, and to avoid attacks, the female climbs the wall of the tree hole with the male on her back. The study suggests that the upside-down spawning behavior in this frog may have evolved as a means of preventing aggressive unpaired males from displacing the amplectant pair from behind and disrupting egg-laying.

Biju et al “This finding is an example of the remarkable diversity of amphibians and reproductive behaviors that are still unknown to science, especially from unexplored regions in biodiversity hotspots of tropical Asia.” said study co-author Professor James Hanken, Curator of Herpetology at the Museum of Comparative Zoology and Professor of Biology in Harvard’s Department of Organismic and Evolutionary Biology. Conservation Challenges and Adaptive Behaviors Although Minervarya charlesdarwini appears to be an obligate phytotelm-breeder, the research team frequently observed frogs breeding in unnatural sites in disturbed forests, ranging from artificially watered plastic sapling bags in adjacent plant nurseries to rain-filled, discarded plastic, glass, or metal containers left as trash at the forest edge. The lack of adequate breeding sites due to habitat loss and competition for limited resources may be driving the Charles Darwin’s frog to breed in such unnatural sites. However, this species may not be able to survive in the face of increasing human dominance and rapidly changing landscapes on the small islands where they live. The study calls for increased attention to the conservation of this endemic and threatened species (currently IUCN Red listed as “Vulnerable”), and to protection of its specialized and vulnerable microhabitats to maintain adequate availability of natural breeding sites. “The frogs’ use of trash for breeding is both surprising and worrying. We now need to know its causes and long-term consequences, and devise ways to protect the natural breeding sites that are critical for survival of the species,” said Sonali Garg, a Biodiversity Postdoctoral Fellow at Harvard’s Museum of Comparative Zoology, who co-led the study. Research Methodology The field-based project was carried out over three years in the remote islands of the Andaman archipelago, which lies in the Bay of Bengal. Researchers spent over 55 nights during the monsoon season to study the secretive reproductive behavior of these tiny frogs.

Credit: UPF /CNIC A new study led by Spanish researchers describes a new mechanism for muscle repair after physiological damage relying on the rearrangement of muscle fiber nuclei, and independently of muscle stem cells. Muscle is known to regenerate through a complex process that involves several steps and relies on stem cells. Now, a new study led by researchers at Pompeu Fabra University (UPF, Spain)/Centro Nacional de Investigationes Cardiovasculares (CNIC, Spain)/CIBERNED (Spain) and Instituto de Medicina Molecular João Lobo Antunes (iMM, Portugal), published on 15 October in the journal Science, describes a new mechanism for muscle repair after physiological damage relying on the rearrangement of muscle fiber nuclei, and independently of muscle stem cells. This protective mechanism paves the way to a broader understanding of muscle repair in physiology and disease. Skeletal muscle tissue, the organ responsible for locomotion, is formed by cells (fibers) that have more than one nucleus, an almost unique feature in our body. Despite the plasticity of these fibers, their contraction can be associated with muscle damage. William Roman, first author of the study and researcher at UPF, explains: “Even in physiological conditions, regeneration is vital for muscle to endure the mechanical stress of contraction, which often leads to cellular damage.” Although muscle regeneration has been investigated in depth in recent decades, most studies centered on mechanisms involving several cells, including muscle stem cells, which are required when extensive muscle damage occurs.” “In this study, we found an alternative mechanism of muscle tissue repair that is muscle-fiber autonomous,” says Pura Muñoz-Cánoves, ICREA professor and principal investigator at UPF and the CNIC, and study leader. Researchers (including Antonio Serrano (UPF) and Mari Carmen Gómez-Cabrera (University of Valencia and INCLIVA) used different in vitro models of injury and models of exercise in mice and humans to observe that upon injury, nuclei are attracted to the damage site, accelerating the repair of the contractile units. Next, the team dissected the molecular mechanism of this observation: “Our experiments with muscle cells in the laboratory showed that the movement of nuclei to injury sites resulted in the local delivery of mRNA molecules. These mRNA molecules are translated into proteins at the site of injury to act as building blocks for muscle repair,” explains William Roman. “This muscle fiber self-repair process occurs rapidly both in mice and in humans after exercise-induced muscle injury, and thus represents a time- and energy-efficient protective mechanism for the repair of minor lesions,” adds Pura Muñoz-Cánoves. In addition to its implications for muscle research, this study also introduces more general concepts for cell biology, such as the movement of nuclei to injury sites. “One of the most fascinating things about these cells is the movement during the development of their nuclei, the biggest organelles inside the cell, but the reasons why nuclei move are largely unknown. Now, we have shown a functional relevance for this phenomenon in adulthood during cell repair and regeneration,” says Edgar R. Gomes, group leader at the Instituto de Medicina Molecular and a professor at the Faculty of Medicine at the University of Lisbon, who co-led the study. On the importance of these discoveries, Pura Muñoz-Cánoves, Antonio Serrano, and Mari Carmen Gómez-Cabrera agree that: “This finding constitutes an important advance in the understanding of muscle biology, in physiology (including exercise physiology) and muscle dysfunction.” Reference: “Muscle repair after physiological damage relies on nuclear migration for cellular reconstruction” by William Roman, Helena Pinheiro Mafalda R.

Smithsonian researchers have discovered that bioluminescence in octocorals dates back 540 million years, challenging previous estimates and highlighting the trait’s evolutionary importance. This finding could lead to deeper understanding and improved conservation of these marine organisms.

Credit: NOAA Office of Ocean Exploration and Research, Deepwater Wonders of Wake Study explores an ancient lineage of marine invertebrates, including soft corals, pushes back the previous oldest dated example of trait by nearly 300 million years. According to a new study by scientists from the Smithsonian’s National Museum of Natural History, bioluminescence originated in animals at least 540 million years ago among a group of marine invertebrates known as octocorals. The results, published in the Proceedings of the Royal Society B, push back the previous record for the luminous trait’s oldest dated emergence in animals by nearly 300 million years, and could one day help scientists decode why the ability to produce light evolved in the first place. Bioluminescence—the ability of living things to produce light via chemical reactions—has independently evolved at least 94 times in nature and is involved in a huge range of behaviors including camouflage, courtship, communication, and hunting. Until now, the earliest dated origin of bioluminescence in animals was thought to be around 267 million years ago in small marine crustaceans called ostracods. But for a trait that is literally illuminating, bioluminescence’s origins have remained shadowy. The bamboo octocoral Isidella sp. displaying bioluminescence in the Bahamas in 2009. Credit: Sönke Johnsen “Nobody quite knows why it first evolved in animals,” said Andrea Quattrini, the museum’s curator of corals and senior author on the study. But for Quattrini and lead author Danielle DeLeo, a museum research associate and former postdoctoral fellow, to eventually tackle the larger question of why bioluminescence evolved, they needed to know when the ability first appeared in animals. Research Methodology and Findings In search of the trait’s earliest origins, the researchers decided to peer back into the evolutionary history of the octocorals, an evolutionarily ancient and frequently bioluminescent group of animals that includes soft corals, sea fans and sea pens. Like hard corals, octocorals are tiny colonial polyps that secrete a framework that becomes their refuge, but unlike their stony relatives, that structure is usually soft. Octocorals that glow typically only do so when bumped or otherwise disturbed, leaving the precise function of their ability to produce light a bit mysterious. “We wanted to figure out the timing of the origin of bioluminescence, and octocorals are one of the oldest groups of animals on the planet known to bioluminesce,” DeLeo said. “So, the question was when did they develop this ability?” Not coincidentally, Quattrini and Catherine McFadden with Harvey Mudd College had completed an extremely detailed, well-supported evolutionary tree of the octocorals in 2022. Quattrini and her collaborators created this map of evolutionary relationships, or phylogeny, using genetic data from 185 species of octocorals.

Credit: NOAA Office of Ocean Exploration and Research With this evolutionary tree grounded in genetic evidence, DeLeo and Quattrini then situated two octocoral fossils of known ages within the tree according to their physical features. The scientists were able to use the fossils’ ages and their respective positions in the octocoral evolutionary tree to date to figure out roughly when octocoral lineages split apart to become two or more branches. Next, the team mapped out the branches of the phylogeny that featured living bioluminescent species. With the evolutionary tree dated and the branches that contained luminous species labeled, the team then used a series of statistical techniques to perform an analysis called ancestral state reconstruction. “If we know these species of octocorals living today are bioluminescent, we can use statistics to infer whether their ancestors were highly probable to be bioluminescent or not,” Quattrini said. “The more living species with the shared trait, the higher the probability that as you move back in time that those ancestors likely had that trait as well.” The researchers used numerous different statistical methods for their ancestral state reconstruction, but all arrived at the same result: Some 540 million years ago, the common ancestor of all octocorals were very likely bioluminescent. That is 273 million years earlier than the glowing ostracod crustaceans that previously held the title of earliest evolution of bioluminescence in animals. DeLeo and Quattrini said that the octocorals’ thousands of living representatives and relatively high incidence of bioluminescence suggests the trait has played a role in the group’s evolutionary success. While this further begs the question of what exactly octocorals are using bioluminescence for, the researchers said the fact that it has been retained for so long highlights how important this form of communication has become for their fitness and survival. Future Research Directions and Conservation Now that the researchers know the common ancestor of all octocorals likely already had the ability to produce its own light, they are interested in a more thorough accounting of which of the group’s more than 3,000 living species can still light up and which have lost the trait. This could help zero in on a set of ecological circumstances that correlate with the ability to bioluminesce and potentially illuminate its function. To this end, DeLeo said she and some of her co-authors are working on creating a genetic test to determine if an octocoral species has functional copies of the genes underlying luciferase, an enzyme involved in bioluminescence. For species of unknown luminosity, such a test would enable researchers to get an answer one way or the other more rapidly and more easily. Aside from shedding light on the origins of bioluminescence, this study also offers evolutionary context and insight that can inform monitoring and management of these corals today. Octocorals are threatened by climate change and resource-extraction activities, particularly fishing, oil and gas extraction and spills, and more recently by marine mineral mining. This research supports the museum’s Ocean Science Center, which aims to advance and share knowledge of the ocean with the world. DeLeo and Quattrini said there is still much more to learn before scientists can understand why the ability to produce light first evolved, and though their results place its origins deep in evolutionary time, the possibility remains that future studies will discover that bioluminescence is even more ancient.
