The Fos gene plays a key role in forming stable brain maps for navigation, linking molecular processes to memory and behavior. Research in mice illuminates the molecular mechanisms that underlie spatial mapping in the brain Researchers found that a gene called Fos plays a key role in helping the brain use specialized navigation cells to form and maintain spatial maps The findings bring us one step closer to a complete understanding of how the brain creates memories of spatial maps for navigation Anytime we venture into a new location, our brain’s built-in GPS immediately activates and begins to form a spatial map of our surroundings. Over a period of days and even weeks, this map may be solidified as a memory that we can recall to help us navigate more easily whenever we return to that particular place. Just how the brain forms these spatial maps is astoundingly complex. It is a process that involves an intricate molecular interplay across genes, proteins, and neural circuits to shape behavior. Perhaps unsurprisingly given this immense complexity, the precise steps of this multiplayer interaction have eluded neurobiologists. Now, scientists have made a major advance toward understanding the molecular mechanisms that are involved in the creation of spatial maps in the brain. The researchers worked through a multilab collaboration within the Blavatnik Institute at Harvard Medical School. The new study, conducted in mice and published today (August 24, 2022) in the journal Nature, establishes that a gene called Fos is a key player in spatial mapping, helping the brain use specialized navigation cells to form and maintain stable representations of the environment. “This research connects across the different levels of understanding to make a pretty direct link between molecules and the function of circuits for behavior and memory,” said Christopher Harvey, associate professor of neurobiology at HMS and senior author of the study. “Here we can understand what’s actually underlying the formation and stability of spatial maps.” If the findings translate into humans, they will provide crucial new information about how our brains construct spatial maps. Eventually, this knowledge could help researchers better understand what happens when this process breaks down, as it often does as a result of brain injury or neurodegeneration. The Role of the Hippocampus in Navigation and Memory Lying deep in the brain’s temporal lobe, the hippocampus plays an essential role in learning, memory, and navigation for many species, including mice and humans. Scientists have long known that for navigation, the hippocampus contains specialized neurons called place cells that selectively become active when an animal is at different locations in space. By turning on and off as an animal moves through its environment, place cells essentially construct a map of the surrounding area that can be incorporated into a memory. “My lab has studied spatial navigation for years, including how place cells form a map of the environment and form spatial memories,” Harvey said, and yet “the molecular mechanisms that underlie those processes have been difficult to study in the behaving animal.” To study the molecular cascade involved in this mapping process, Harvey and first author Noah Pettit teamed up with co-senior author Michael Greenberg and author Lynn Yap. Pettit is a research fellow in neurobiology in the Harvey lab, Greenberg is the Nathan Marsh Pusey Professor of Neurobiology at HMS, and Yap is a graduate of the Harvard PhD Program in Neuroscience who did her doctoral work in the Greenberg lab. Fos Expression and Its Link to Place Cells Greenberg’s lab studies the Fos gene, which codes for a transcription factor protein that regulates the expression of other genes. In previous research, Greenberg and his colleagues showed that Fos is expressed minutes after a neuron is activated, making it a useful marker for neural activity in the brain. They also demonstrated that Fos acts as a mediator for different types of neural plasticity, including navigation and memory formation. However, the relationship between Fos and place cells in the hippocampus was not known. The team wondered whether Fos could be involved in how mice form spatial maps as they navigate their environment. To find out, the investigators used a technique developed in Harvey’s lab that places mice in a virtual reality maze: A mouse runs on a ball as it looks at a large, surround screen that displays a spatial navigation task such as solving a maze to find a reward. As the mouse jogs on the ball and performs the task, researchers record neural activity and changes in Fos expression in the hippocampus. In what Greenberg called “a technical tour de force,” Pettit led a series of complicated experiments to unravel the connection between Fos and place cells. The researchers found that in the hours after a mouse performed a navigation task, neurons with high Fos expression were more likely to form accurate place fields — clusters of place cells that signal spatial position — than those with low Fos expression. Moreover, neurons with high Fos expression had place fields that were more reliable over time in indicating spatial position as the mouse repeated the task on subsequent days. “This tells us that on a moment-to-moment basis as the mouse is navigating, the neurons that induce Fos have very robust information about the mouse’s spatial position, which is the key variable needed to solve and remember the task,” Pettit explained. When the team knocked out Fos in a subset of neurons within the hippocampus, they observed that those cells had less accurate spatial maps of the environment than nearby neurons with normal Fos expression. Also, the maps in cells lacking Fos were less stable across days, and thus, were less reliable as memories of the environment. Fos’s Role in Maintaining Stable Spatial Maps “Fos seems to be important for maintaining the stability and accuracy of place cells, and representing a spatial map in the brain over time,” Greenberg said. “There have been a lot of studies on Fos and there have been a lot of studies on place cells, but this is one of the first papers that directly connects the two,” Harvey added, “It opens a lot of exciting new directions for investigating these mechanisms.” For instance, Greenberg would like to delve into the specific molecules and cells that are involved as Fos helps the brain form and maintain stable spatial maps over time. He also wants to understand the different roles Fos may play as spatial map memories are transferred from the hippocampus to other brain regions. In a similar vein, Harvey is interested in whether Fos is part of the process by which spatial map memories are solidified during sleep. Although the study was done in mice, the scientists noted that much of the system is conserved across species, including humans. If the findings can be confirmed in humans, they could help scientists understand how our brains form spatial maps and what happens when we lose this ability due to injury or disease. Beyond the science, the researchers emphasized that the research represents an unusual partnership between a laboratory that studies cellular and molecular mechanisms and one that focuses on animal behavior and neural circuits. “Our two laboratories are about as far from each other in terms of what we do as any in the department, but we’ve come together to study how molecules interact with neural circuits that control learning, memory, and behavior,” Greenberg said. “This was a natural and exciting collaboration to learn that Fos plays a role in spatial memories and spatial navigation,” Harvey agreed. “It’s hard to be an expert in all these different levels of neurobiology, but by working together, the two labs have been able to bridge the gap.” Reference: “Fos ensembles encode and shape stable spatial maps in the hippocampus” by Noah L.

Credit: Bat illustration from “Voyage dans l’Amérique méridionale” (1846-1847) by Alcide d’Orbigny. Moth illustration from “Illustrations of Exotic Entomology,” (1837) by Dru Drury. Researchers found that Luna moth tails primarily serve to misdirect bat attacks, with no additional mating advantages or increased visibility to bird predators. In a pair of complementary studies, researchers took a close look at Luna moth (Actias luna) tails through the eyes of birds and female moths to test the tails’ role in predation and sexual selection. Scientists have known for about a decade that Luna moths — and other related silkmoths — use their long, trailing tails to misdirect bat attacks. “They have projections off the back of the hindwing that end in twisted, cupped paddles,” said Juliette Rubin, a doctoral student at the Florida Museum of Natural History and lead author of both studies. “From experimental work with bats and moths in a flight room, we’ve found that these structures seem to reflect bat sonar in such a way that bats often aim their attacks at the tails instead of the main body.” Traits that evolve for one specific function can often be co-opted by natural selection for another, and Rubin wondered whether the twisted tails of Luna moths might come with any additional benefits or hidden costs. Male Luna moths doff their tails, retain their charm Silkmoths have independently evolved tails on multiple occasions across three continents, and the appendages can vary significantly in length. Hind wings in some species can extend to more than twice the size of the moth’s wingspan, and the longer the tail, the more likely a moth will successfully thwart a prowling bat. But far from being drab, utilitarian decoys meant only for sonar-sensing bats, silkmoth tails are often visually stunning, like decorative streamers trailing behind a kite. Across the animal and plant kingdoms, many of the most colorful and alluring structures are used to attract mates or pollinators, and scientists suspected the same might be true of silkmoth tails. This type of dual function for a single trait isn’t without precedent. The vivid colors of strawberry poison dart frogs (Oophaga pumilio) both deter predators and help males attract mates; male deer and other ungulates use their antlers to fight off rivals and signal their vigor to females; and moths that use clicks or chirruping sounds to disrupt bat echolocation can compose duets using the same sounds during courtship. Luna moths have neither mouths to produce sound nor ears to hear it, but they do have sensitive eyes and powerful scent-detecting antennae. When female Luna moths are ready to mate, they perch in one place and emit a pheromone, a single molecule of which is enough to trigger a male antenna. The males of closely related Indian moon moths (Actias selene) can find females from more than six miles away by following the pheromone plume to its source. “We don’t know how many males are traveling to a female each night,” Rubin said. “It’s entirely possible she’s able to call in multiple suitors and potentially have her pick.” Rubin put this idea to the test, setting up mating experiments in which a female Luna moth was enclosed in a flight box with two males: one with normal hind wings, and one with its tails removed. Initially, the data seemed to suggest that females preferred males whose wings remained intact, but additional controlled experiments demonstrated that this was more likely an incidental effect of the tail removal. During trials in which both males had their wings clipped, and one had the tails glued back on, there was no difference in their mating success. Do tails make Luna moths invisible to bats but conspicuous to birds? Having demonstrated tail wings likely weren’t conferring any additional benefits beyond survival, Rubin wanted to see whether they had any obvious drawbacks. Their long tails effectively throw off pursuing bats by creating a decoy target, but bats aren’t the only adversaries Luna moths have to avoid. Their electric green tails with bright, pink parfait borders might make Luna moths noticeable to birds and other visually oriented predators that hunt during the day. Other organisms contend with similar tradeoffs. The bioluminescent displays of fireflies make it easier for males to locate potential mates, but it also makes them stand out to nocturnal frogs and geckoes. Luna moths live incredibly short lives, during which they can afford to lose a tail or two. Once they emerge from their cocoons, the moths have about a week to find a mate and reproduce before dying. “This creates a very intense period of adulthood, where surviving the night is of the utmost importance,” Rubin said. Luna moths are mostly inactive during the day, reducing their chances of being nabbed midair. If they don’t do a good enough job concealing themselves, however, they run the risk of not surviving to nightfall. Rubin wanted to know if their visually elaborate tails put Luna moths at a disadvantage in this high-stakes game of hide-and-seek. To find out, she and her colleagues wrapped mealworms in pastry dough in the shape and size of Luna moth bodies, to which they attached real wings, half of which had tails. They partially hid these moth replicas among branches and leaves in an aviary, then introduced a succession of Carolina wrens (Thryothorus ludovicianus), recording how many of the snacks the birds located and ate. The results conclusively indicate that the tails had no effect on the birds’ ability to locate the fake moths. This might seem odd to us, Rubin said, because we’re such visually oriented animals. But there’s evidence that suggests birds might rely on search images when trying to distinguish food items from patterns in the background. Humans do this too. When trying to complete a Where’s Waldo puzzle, people often look for the characteristic red, horizontal lines of Waldo’s shirt while scanning across the page. It’s possible that Luna moth tails don’t match the typical moth and butterfly mold that birds expect to see while foraging, the equivalent of Waldo wearing a solid red shirt rather than his signature stripes. While not indicative of all silkmoths, the studies suggest that these stunning and complex structures evolved for a single function in Luna moths. “When we see these really obvious physical features in animals, we’re often drawn into stories we’ve heard about them,” Rubin said. “One is that conspicuous traits are for attracting mates or competing with rivals, and another is that these very showy traits must come with a cost. Both of these studies show it’s really important to test those assumptions. A trait that’s obvious to us, as visual creatures, might not stand out to the predators that hunt them, and the traits that we think are dynamic and alluring might not seem that way to a potential mate.” The studies were published in the journals Biology Letters and Behavioral Ecology.

Satellite observations show rising temperatures are causing Earth’s coldest forests to shift northward. New research from Northern Arizona University shows rising temperatures are causing Earth’s coldest forests to shift northward, raising concerns about biodiversity, an increased risk of wildfires, and mounting impacts of climate change on northern communities. Logan Berner, assistant research professor in the School of Informatics, Computing, and Cyber Systems (SICCS), and Scott Goetz, Regents’ professor and director of the GEODE Lab, authored the article, “Satellite observations document trends consistent with a boreal forest biome shift,” which was published today (February 24, 2022) in Global Change Biology. The boreal forest is a belt of cold-tolerant conifer trees that stretches nearly 9,000 miles (14,500 kilometers) across northern North America and Eurasia; it accounts for almost a quarter of the Earth’s forest area and is the coldest—though mostly rapidly warming—forest biome. For this study, the researchers used 40 years of moderately fine (30m) resolution satellite observations and various geospatial climate-related datasets of the boreal forest and assessed where and why vegetation greened and browned during recent decades. “Greening” indicates higher rates of vegetation growth, which can happen when climate warming promotes growth of trees and shrubs, as was observed near the arctic and alpine tree lines. “Browning” indicates lower rates of vegetation growth and potentially vegetation death, such as when hotter and drier conditions suppress tree growth and kill trees. “There is emerging evidence that climate change is causing boreal trees and shrubs to expand into arctic and alpine tundra, while at the same time causing trees to become more stressed and die along the warm southern margins of the boreal forest,” Berner said. “These dynamics could lead to a gradual northward shift in the geographic extent of the boreal forest biome, but the extent to which such changes are already underway has remained unclear.” What they found wasn’t exactly a surprise. Vegetation became greener across much of the cold northern margins of the boreal forest; warmer conditions led to increased vegetation growth and enabled trees and shrubs to expand into arctic and alpine tundra. Conversely, vegetation became browner along parts of the warm southern margins of this biome as a result of hotter, drier conditions increasing tree stress and death. Intriguingly, Berner said, vegetation was more likely to become greener in areas with high soil nitrogen, indicating that soil nutrient availability is an important constraint on the response of boreal vegetation to climate change. “The boreal forest ecosystem is changing in many ways over recent decades, and those changes are often linked with increasing fire disturbance,” Goetz said. “Here we intentionally focused on areas that were not recently disturbed by fire so we could tease out the effect of climate change. Our hypotheses about what would happen were verified by this analysis—forests are getting more productive in the cooler northern and higher elevation areas, and they’re getting less productive as a result of hot air masses and drying in the warmer and more southerly areas. We fully expect that will continue and probably intensify in the years to come.” What a changing biome means for the forest Changes in vegetation could affect both plant and animal biodiversity, especially species like caribou and moose, which have specific foraging preferences (e.g. deciduous shrubs and trees). These wildlife species are critical sources of food for subsistence communities in the boreal-tundra ecotone. Changes in vegetation along both the northern and southern margins of the boreal forest will impact wildfire regimes, likely increasing the risk of more severe fires. Changes in vegetation also impact the stability of carbon-rich permafrost soils and absorption of solar energy by the land surface in ways that could accelerate climate warming. Moreover, increasing tree mortality could have widespread implications for forest products while also leading to further degradation of semi-continuous and sporadic permafrost. These future effects are not limited to the geographical area around the forest. “Fundamentally, greenhouse gas emissions from human activities are causing Earth’s climate to warm, which in turn is leading the boreal forest to shift northward, as well as impacting other ecosystems across the planet,” Berner said. “To minimize adverse impacts of climate change, efforts are needed to dramatically reduce greenhouse gas emissions, especially related to fossil fuel consumption and deforestation. Furthermore, northern communities need to plan for potential changes in vegetation that could impact resource availability (e.g. wildlife, timber) and wildfire risk.” This study is part of a larger initiative funded by NASA’s Arctic-Boreal Vulnerability Experiment (ABoVE) that will include further efforts to understand the extent, nature, cause, and consequence of an emerging boreal biome shift. Goetz is the science lead for ABoVE. Reference: “Satellite observations document trends consistent with a boreal forest biome shift” by Logan T. Berner and Scott J.
