Through video analysis, the researchers identified multiple honey bee behaviors inside the hive, including hive remodeling, surface cleaning, self-grooming, brood care, pollen and nectar storage, and even cannibalism! Credit: Diego Perez-Lopez, PLOS, CC-BY 4.0 Unique videos capture detailed instances of rare honey bee behaviors like mouth-to-mouth larval feedings. Unique video from within beehives provides special insight into honey bee behaviors, according to a study published March 17, 2021 in the open-access journal PLOS ONE by Paul Siefert from Goethe-Universität, Germany, and colleagues. Though the European honey bee (Apis mellifera) famously lives in large and complex colonies, it’s the collective behavior of the hive’s unique individuals that determines the colony’s success — behaviors such as nest building, foraging, storing and ripening food, brood nursing, temperature regulation, hygiene, or hive defense. Most of these activities happen within the structure of the hive itself and aren’t easily observable — but in this study, Siefert and colleagues were able to video record individual honeycomb frames and even cells from within special glass-framed observation hives, providing new insights into honey bee behavior at the individual level. For these videos, the authors continuously recorded truncated honeycomb cells within the brood area of their observation hives with the frames turned 90 degrees for visibility, permitting a sideways view into the cells in the middle of the colony. The recordings show a range of worker, offspring, and queen behaviors within the brood cells, including the queen’s egg laying; embryonic hatching and larval cocooning; nurse worker bees’ inspection and feeding of larva; workers’ use of wax scales and existing nest material to remodel combs; storage of pollen and nectar in cells; and hygienic practices, such as cannibalism, grooming and surface cleaning. Additionally, Siefert and colleagues captured several processes previously undocumented, such as mouth-to-mouth feeding from nurse bees to larvae as well as nurse bee thermoregulation within cells containing the developing brood prompting the descent of eggs within their comb cells. The wealth of video recordings providing specific instances of honeybee behavior will prove insightful for scientists as well as beekeepers and the general public. The authors especially hope their material will help raise awareness of the critical declines in pollinator and bee populations, and encourage the use of their work for educational purposes. The authors add: “In this study, the authors provide a comprehensive source of online video material that offers a view of honey bee behavior within comb cells of a functioning colony. By providing a new mode of observation for the scientific community, beekeepers, and the general public the authors call attention to the general decline of insect biomass and diversity.” Interview with author Dr. Paul Siefert PLOS: What first drew you to study honey bees and their behaviors? Dr. Siefert: During my studies at the Goethe-University Frankfurt I became interested in eusocial behavior after some practical work with squirrel monkeys. Eusocial behavior is the highest level of social organization and includes cooperative brood care, overlapping generations, and division of labor. Interestingly, except for mammals only a few arthropods live eusocial, such as ants, termites, and honey bees. PLOS: What did you choose to investigate in this study, and why? Siefert: In a previous project, my colleagues and I investigated the effects of insecticides on honey bee brood care within the colony, using long-term video recordings. Since there was high interest in my videos from developing bees within the comb cells in the scientific community and the public, I decided to publish further behavioral videos that were also recorded during this time. Our primary goal is to educate beekeepers and the public about the fascinating methods that bees have for organizing their colony. PLOS: What are the key findings from your research? Siefert: We were able to visualize behaviors within the comb cells, that are usually hidden from sight, and until recently, were primarily described through texts and line drawings, which lack the dynamics of moving images. This provides insight into worker behaviors, including the use of wax scales and existing nest material to remodel combs, storing pollen and nectar in cells, brood care and thermoregulation, and hygienic practices, such as cannibalism, grooming and surface cleaning. PLOS: What most surprised or interested you about your findings? Siefert: Generally, I am fascinated how honey bees are able to choose the beneficial decision for the colony, and wonder how they perceive their surroundings and information, and if their actions are based on learning or instinct. Specifically, I was surprised to see that the first of two workers, which successively entered the same cell that had parasites in it (the Varroa destructor mite), did not bother at all, but the next one attacked the mites vigorously. PLOS: What do you hope your findings might lead to, and what are the next steps for your research? Siefert: With our videos, we want to bring the processes of a fully functioning social insect colony into classrooms and homes, facilitating ecological awareness in modern times. We encourage the non-commercial use of our material to educate beekeepers, the media and the public and, in turn, call attention to the general decline of insect biomass and diversity. In the upcoming months I want to use the video method for research that requires the collection of precisely age-determined eggs.

Research on human foot evolution highlights the importance of the medial longitudinal arch and explores the variability in foot morphology, influenced by factors like lifestyle, footwear, and genetic traits. Credit: SciTechDaily.com A comprehensive study reveals new insights into the evolution and complexity of the human foot, focusing on the medial longitudinal arch and its significance in differentiating Homo sapiens from primates. “The human foot is one of the most complex masterpieces of evolution, a work of art in biomechanics: not only it allows us to walk, run and jump, but it is also a true witness of our past and our present,” remarks Rita Sorrentino, researcher at the Department of Biological, Geological and Environmental Sciences at the University of Bologna and first author of an extensive study, published in Communication Biology, shedding new light on the complex evolution of our feet. The research activity involving researchers from the Rizzoli Orthopaedic Institute and the University of Pisa focused on the medial longitudinal arch of the foot: a unique characteristic that differentiates our specie — Homo sapiens — from non-human primates. Understanding the Longitudinal Arch and Flat Feet The longitudinal arch is a functional adaptation that allows the foot to switch from a shock absorber function to lever during the phases of contact and detachment with the ground, a mechanism that allows us to have an efficient bipedal walk. Despite its importance, however, it is still unclear when this characteristic appeared in the course of our evolutionary history. The topic of “flat feet” complicates the picture even more: it is a widespread condition that consists in a more or less pronounced flattening of the medial longitudinal arch. “Not all flat feet are the same and yet there is not a worldwide clinical definition of flat feet in human beings,” explained Alberto Leardini and Claudio Belvedere, scientists from the Laboratory of Movement Analysis and Functional Evaluation of Prosthesis of the Rizzoli Orthopaedic Institute and among the authors of the study. Anatomical position of the navicular (orange) in the medial column of the foot (top). Along the bottom, renderings of an archaeological H. sapiens navicular (from the Frassetto identified human skeletal collection – University of Bologna) are illustrated in proximal (bottom left) and distal (bottom right) views. Placement of landmark and semi-landmark configurations are shown: five fixed landmarks (black), 46 curved semi-landmarks (light blue) describing corresponding articular surface contours, and 34 surface semi-landmarks (orange) on articular surfaces and the navicular tuberosity. Credit: Sorrentino et al. Communications Biology Navicular Bone and Foot Morphology Scientists have focused in particular on the role of the navicular bone in order to find answers, the keystone of the medial longitudinal arch of the foot. “The results of this research highlight the variation of navicular morphology among flat-footed people and people with a well-developed longitudinal arch,” explains Maria Giovanna Belcastro, professor at the Department of Biological, Geological and Environmental Sciences at the University of Bologna and research coordinator. “More specifically, people who developed flat feet during adulthood show differences concerning the navicular bone shape compared to those with regular arches or with inborn flat feet.” This development raises questions about the nature of inborn flat feet, suggesting that they may represent a normal variant of foot morphology, and thus highlighting the importance of bone morphology in the structure of the foot arch. Foot Morphology Influenced by Lifestyle Scientists also focused on another fascinating topic: differences within modern Homo sapiens population groups. Indeed, the results suggest that the development of the longitudinal arch may be influenced by factors such as the type of footwear, lifestyle, and prevailing locomotion strategies. “We have observed that individuals belonging to hunter-gatherer groups, who live without footwear, show feet that are more flexible in mobility and relatively flatter than those of populations using modern footwear,” explains Damiano Marchi, professor at the University of Pisa, one of the discoverers of Homo naledi and one of the coordinators of the study. “These differences may come from different cultural lifestyles and practices: the feet of hunter-gatherer populations could therefore represent a form closer to that of our prehistoric ancestors.” Comparing Modern and Ancient Feet The investigation also compared the structure of our feet with fossils of ancient Homo sapiens and other human species of the past. “Some of the fossils analyzed, such as those of Homo floresiensis, Australopithecus afarensis, and Homo naledi, show features in the navicular more similar to those of large non-human primates, suggesting an adaptation to both an arboreal and bipedal lifestyle,” explains Stefano Benazzi, professor at the Department of Cultural Heritage at the University of Bologna, one of the study coordinators. “At the same time, the Homo habilis fossils seem to have a configuration more similar to the feet of modern humans, indicating a possible presence of the longitudinal arch; however, this does not exclude the possible presence of a flat foot similar to today’s congenital flat feet, given the morphological similarity and proximity of the navicular to that of individuals with a developed longitudinal arch of the foot. Evolving Perspectives on Human Feet The research ultimately offers a new perspective on the evolution of the human foot and its variability, contributing to our understanding of how this body part has adapted to bipedal locomotion. Rita Sorrentino, first author of the study explains: “Our foot is a true witness to our past and our present, a fascinating chapter in the great history of human evolution. The results of this investigation provide a comprehensive overview of the morphological variability of the human foot throughout evolution and raise important questions about congenital flat feet, suggesting that they may represent a normal variant of human foot morphology.” Reference: “Morphological and evolutionary insights into the keystone element of the human foot’s medial longitudinal arch” by Rita Sorrentino, Kristian J.

Rice University’s Lauren Howe-Kerr, left, and Adrienne Correa discovered that symbiont algae found on corals in French Polynesia are able to reproduce via mitosis and sex. That could make it easier to develop algae that better protect coral reefs from the effects of climate change. Credit: Brandon Martin/Rice University Rice biologists’ discovery can be used to help climate-challenged reefs survive for now. A little more sexy time for symbionts could help coral reefs survive the trials of climate change. And that, in turn, could help us all.  Researchers at Rice University and the Spanish Institute of Oceanography already knew the importance of algae known as dinoflagellates to the health of coral as the oceans warm, and have now confirmed the tiny creatures not only multiply by splitting in half, but can also reproduce through sex.  That, according to Rice marine biologist Adrienne Correa and graduate student Lauren Howe-Kerr, opens a path toward breeding strains of dinoflagellate symbionts that better serve their coral partners.  Dinoflagellates not only contribute to the stunning color schemes of corals, but critically, they also help feed their hosts by converting sunlight into food.  “Most stony corals cannot survive without their symbionts,” Howe-Kerr said, “and these symbionts have the potential to help corals respond to climate change. These dinoflagellates have generation times of a couple months, while corals might only reproduce once a year.  “So if we can get the symbionts to adapt to new environmental conditions more quickly, they might be able to help the corals survive high temperatures as well, while we all tackle climate change.” In an open-access study in Nature’s Scientific Reports, they wrote the discovery “sets the stage for investigating environmental triggers” of symbiont sexuality “and can accelerate the assisted evolution of a key coral symbiont in order to combat reef degradation.” A coral of the type studied by scientists at Rice University is protected by dinoflagellates (inset), algae that turn sunlight into food to feed and protect reefs. The study showed the algae are able to reproduce via sex, opening a path toward accelerated evolution of strains that can better protect coral from the effects of climate change. Credit: Inset by Carsten Grupstra/Rice University; coral image by Andrew Thurber/Oregon State University To better understand the algae, the Rice researchers reached out to Rosa Figueroa, a researcher at the Spanish Institute of Oceanography who studies the life cycles of dinoflagellates and is lead author on the study. “We taught her about the coral-algae system and she taught us about sex in other dinoflagellates, and we formed a collaboration to see if we could detect symbiont sex on reefs,” Howe-Kerr said. “In genomic datasets of coral dinoflagellates, researchers would see all the genes coral symbionts should need to reproduce sexually, but no one had been able to see the actual cells in the process,” said Correa, an assistant professor of biosciences. “That’s what we got this time.”  The discovery follows sampling at coral reefs in Mo’orea, French Polynesia, in July 2019 and then observation of the algae through advanced confocal microscopes that allow for better viewing of three-dimensional structures.  A dinoflagellate tetrad cell that will soon split into four separate cells, captured by Rice University scientists through a confocal microscope. The cell’s four nuclei are depicted in red. Researchers at Rice and in Spain determined from experiments that these symbionts, taken from a coral colony in Mo’orea, French Polynesia, are able to reproduce both through mitosis and via sex. Credit: Correa Lab/Rice University “This is the first proof that these symbionts, when they’re sequestered in coral cells, reproduce sexually, and we’re excited because this opens the door to finding out what conditions might promote sex and how we can induce it,” Howe-Kerr said. “We want to know how we can leverage that knowledge to create more genetic variation.” “Because the offspring of dividing algae only inherit DNA from their one parent cell, they are, essentially, clones that don’t generally add to the diversity of a colony. But offspring from sex get DNA from two parents, which allows for more rapid genetic adaptation,” Correa said.  Symbiont populations that become more tolerant of environmental stress through evolution would be of direct benefit to coral, which protect coastlines from both storms and their associated runoff.  “These efforts are ongoing to try to breed corals, symbionts, and any other partners to make the most stress-resistant colonies possible,” Correa said. “For coral symbionts, that means growing them under stressful conditions like high temperatures and then propagating the ones that manage to survive.  “After successive generations we’ll select out anything that can’t tolerate these temperatures,” she said. “And now that we can see there’s sex, we can do lots of other experiments to learn what combination of conditions will make sex happen more often in cells. That will produce symbionts with new combinations of genes, and some of those combinations will hopefully correspond to thermotolerance or other traits we want. Then we can seed babies of the coral species that host that symbiont diversity and use those colonies to restore reefs.” Reference: “Direct evidence of sex and a hypothesis about meiosis in Symbiodiniaceae” by R.
