The scientists were able to learn how the new species has evolved through the use of morphometrics, stable isotope analysis, and genome sequencing. An Evolutionary Biologist’s Team Has Found a New Type of Speciation The evolution of a new species by hybridization of two previously described species with no change in chromosomal number is very unusual in the animal world. So far, only a few empirically acknowledged cases of this spontaneous mode of evolution (from one generation to the next) known as homoploid hybridization exist. A study led by Axel Meyer, Professor of Zoology and Evolutionary Biology at the University of Konstanz, has successfully demonstrated the emergence of a new hybrid species in cichlid fishes. This is likely the first instance of this genetic speciation method in vertebrates. The researchers reveal that a new hybrid species has emerged from the cichlid A. sagittae and A. xiloaensis in the crater lake Xiloá in Nicaragua using whole genome sequencing of more than 120 individuals as well as a number of other techniques. Their findings were recently published in the journal Nature Communications.  The study team discovered fish in the crater lake Xiloá back in 2018 that resembled hybrids of the two cichlid species. Furthermore, genetic testing revealed that these fish’s genomes had elements of both species, depending on the marker. “We can now sequence the complete genomes of the fishes and look much more closely at how the genome of the hybrids is composed. In fact, it was possible to identify on the chromosome which part of the hybrid originated from A. sagittae and which from A. xiloaensis” says Axel Meyer.

Credit: Ad Konings; Cichlid Press The Majority of Fishes Reproduce Among Themselves The study team was also able to discover that the majority of individuals of the new species reproduced solely among themselves due to the detail of the markings, indicating that it is indeed a new species. It is also plausible that hybrids developed as a result of a “mistake” in mate selection, which would explain why their offspring could prove infertile or hybrid animals that mate with one of the two parent species again (“backcrossing”). The new, very young species, emerging within a few hundred generations, is not directly intermediate between the two parent species, A. sagittae and A. xiloaensis, neither morphologically, physiologically, nor ecologically. Instead, the hybrids show aspects of a transgressive phenotype with traits not found in either parent species. As a result, they occupy a different ecological niche than their two parent species, allowing them to coexist in the lake. Ecological Consequences From the Physique The fishes differ from their ancestors in the shape of their caudal root – the part of the body where the tail fin attaches. “Possibly that is why they are better swimmers. You find this type of body proportion often in fish that can accelerate very quickly”, Meyer explains. This allows the hybrids to roam different feeding grounds than the other four species in lake Xiloá, including both parental species, of which one is an elongated species living in open water, while the other has a deeper-bodied shape and lives close to the shore. With stable isotope analysis of the animals, the researchers were able to show that the prey of the new species consists of other fish, crabs, and shrimp – prey that is already very high on the food chain. Probably the individuals of the new species are the most successful predators of the lake. Unique Ecological Niche The new hybrid species occupies a unique ecological niche, which is very important in a small ecosystem like Lake Xiloá, whose diameter is only a little more than one kilometer. “The prerequisite for individual species coexisting for long periods of time in such a limited habitat is that they are no competition for each other”, says Axel Meyer. Especially since the new speciation does not occur over a large geographic distance, but under sympatric conditions within the same small habitat as that of the original species. Genome sequencing, morphometrics, stable isotope analysis – with this combination of different data sets, the researchers were able to understand how the new species has evolved. In a new study, the researchers examine how often errors occur when hybrid fishes are given the choice of reproducing with each other or with individuals of their parent species. Finally, the question is: How is mate choice controlled genetically?

The studies have implications for certain human conditions characterized by touch dysfunction. According to recent research, the brainstem and spinal cord play a crucial role in processing touch signals as they travel to the brain. Almost everything we do relies on our sense of touch, from simple household chores to navigating potentially dangerous terrain. Scientists have long been curious about how the touch information we obtain with our hands and other parts of our bodies makes its way to the brain to generate the sensations we feel. However, key aspects of touch, such as how the spinal cord and brainstem are involved in receiving, processing, and transmitting signals, remain unknown. Now, two studies from Harvard Medical School researchers provide significant new understandings of how the spinal cord and brainstem contribute to the sense of touch. The study found that the spinal cord and brainstem, which were previously assumed to just be relay centers for touch information, are actively engaged in the processing of touch signals as they travel to higher-order brain regions. One study, recently published in the journal Cell, shows that specialized neurons in the spinal cord form a complex network that processes light touch — think the brush of a hand or a peck on the cheek — and sends this information to the brainstem. In another study, published in the journal Nature, researchers established that direct and indirect touch pathways work together, converging in the brainstem to shape how touch is processed. “These studies focus the spotlight on the spinal cord and the brainstem as sites where touch information is integrated and processed to convey different types of touch. We hadn’t fully appreciated before how these areas contribute to the brain’s representation of vibration, pressure, and other features of tactile stimuli,” said David Ginty, the Edward R. and Anne G. Lefler Professor of Neurobiology in the Blavatnik Institute at HMS and the senior author on both papers. Although the studies were conducted in mice, mechanisms for touch are largely conserved across species, including humans, which means the basics of touch processing could be useful for scientists studying human conditions such as neuropathic pain characterized by touch dysfunction. “This detailed understanding of tactile sensation ― that is, feeling the world through contact with the skin — may have profound implications for understanding how disease, disorder, and injury can affect our ability to interact with the environment around us,” said James Gnadt, program director at the National Institute of Neurological Disorders and Stroke (NINDS), which provided part of the funding for the studies. Overlooked and Underappreciated The historical view of touch is that sensory neurons in the skin encounter a touch stimulus such as pressure or vibration and send this information in the form of electrical impulses that travel directly from the skin to the brainstem. There, other neurons relay touch information to the brain’s primary somatosensory cortex — the highest level of the touch hierarchy — where it is processed into sensation. However, Ginty and his team wondered if and how the spinal cord and brainstem are involved in processing touch information. These areas occupy the lowest level of the touch hierarchy and combine to form a more indirect touch pathway into the brain. “People in the field thought that the diversity and richness of touch came just from sensory neurons in the skin, but that thinking bypasses the spinal cord and brainstem,” said Josef Turecek, a postdoctoral fellow in the Ginty lab and the first author on the Nature paper. Many neuroscientists are not familiar with spinal cord neurons, called postsynaptic dorsal column (PSDC) neurons, that project from the spinal cord into the brainstem — and textbooks tend to leave PSDC neurons out of diagrams depicting the details of touch, Turecek explained. For Ginty, the way that the spinal cord and brainstem have been overlooked in touch brings to mind early research on the visual system. Initially, scientists studying vision thought that all processing occurred in the visual cortex of the brain. However, it turned out that the retina, which receives visual information long before it reaches the cortex, is heavily involved in processing this information. “Analogous to research on the visual system, these two papers address how touch information coming from the skin is processed in the spinal cord and brainstem before it moves up the touch hierarchy to more complex brain regions,” Ginty said. Connecting the Dots In the Cell paper, the researchers used a technique they developed to simultaneously record the activity of many different neurons in the spinal cord as mice experienced various types of touch. They discovered that over 90 percent of neurons in the dorsal horn — the sensory processing area of the spinal cord — responded to light touch. “This was surprising because classically it was thought that dorsal horn neurons in the superficial layers of the spinal cord respond mostly to temperature and painful stimuli. We hadn’t appreciated how light-touch information is distributed in the spinal cord,” said Anda Chirila, a research fellow in the Ginty lab and the co-lead author on the paper with graduate student Genelle Rankin. Moreover, these responses to light touch varied considerably across genetically different populations of neurons in the dorsal horn, which were found to form a highly interconnected and complex neural network. This variation in responses, in turn, gave rise to a diversity of touch information carried from the dorsal horn to the brainstem by PSDC neurons. In fact, when the researchers silenced various dorsal horn neurons, they saw a reduction in the diversity of light-touch information conveyed by PSDC neurons. “We think this information on how touch is encoded in the spinal cord, which is the first site in the touch hierarchy, is important for understanding fundamental aspects of touch processing,” Chirila said. In their other study, published in Nature, scientists focused on the next step in the touch hierarchy: the brainstem. They explored the relationship between the direct pathway from sensory neurons in the skin to the brainstem and the indirect pathway that sends touch information through the spinal cord, as described in the Cell paper. “Brainstem neurons get both direct and indirect input, and we were really curious about what aspects of touch each pathway brings to the brainstem,” Turecek said. To parse this question, the researchers alternately silenced each pathway and recorded the response of neurons in mouse brainstems. The experiments showed that the direct pathway is important for communicating high-frequency vibration, while the indirect pathway is needed to encode the intensity of pressure on the skin. “The idea is that these two pathways converge in the brainstem with neurons that can encode both vibration and intensity, so you can shape responses of those neurons based on how much direct and indirect input you have,” Turecek explained. In other words, if brainstem neurons have more direct than indirect input, they communicate more vibration than intensity, and vice versa. Additionally, the team discovered that both pathways can convey touch information from the same small area of skin, with information on intensity detouring through the spinal cord before joining information on vibration that travels directly to the brainstem. In this way, the direct and indirect pathways work together, enabling the brainstem to form a spatial representation of different types of touch stimuli from the same area. Finally on the Map Up until now, “most people have viewed the brainstem as a relay station for touch, and they haven’t even had the spinal cord on the map at all,” Ginty said. For him, the new studies “demonstrate that there’s a tremendous amount of information processing occurring in the spinal cord and brainstem — and this processing is critical for how the brain represents the tactile world.” Such processing, he added, likely contributes to the complexity and diversity of the touch information that the brainstem sends to the somatosensory cortex. Next, Ginty and the team plan to repeat the experiments in mice that are awake and behaving, to test the findings under more natural conditions. They also want to expand the experiments to include more types of real-world touch stimuli, such as texture and movement. The researchers are also interested in how information from the brain — for example, about an animal’s level of stress, hunger, or exhaustion — affects how touch information is processed in the spinal cord and brainstem. Given that touch mechanisms appear to be conserved across species, such information may be especially relevant for human conditions such as autism spectrum disorders or neuropathic pain, in which neural dysfunction causes hypersensitivity to light touch. “With these studies, we’ve laid the fundamental building blocks for how these circuits work and what their importance is,” Rankin said. “Now we have the tools to dissect these circuits to understand how they’re functioning normally, and what’s changing when something goes wrong.” References: “Mechanoreceptor signal convergence and transformation in the dorsal horn flexibly shape a diversity of outputs to the brain” by Anda M.

Bitty Critter With A Giant Claw Lives Under the Dock at Duke Marine Lab The world’s most technologically advanced robots would lose in a competition with a tiny crustacean. Just the size of a sunflower seed, the amphipod Dulichiella cf. appendiculata has been found by Duke researchers to snap its giant claw shut 10,000 times faster than the blink of a human eye. The claw, which only occurs on one side in males, is impressive, reaching 30% of an adult’s body mass. Its ultrafast closing makes an audible snap, creating water jets and sometimes producing small bubbles due to rapid changes in water pressure, a phenomenon known as cavitation.

Credit: Tomonari Kaji A Unique Combination of Speed and Size Three things make this ultra-fast movement unique said Sarah Longo, who studied the amphipods as part of her postdoctoral studies at Duke: the amphipods’ really small size, the fact that they live in water, and the repeatability of their movements. Other animals have comparable accelerations, but none has the same set of constraints: the jaws of trap-jaw ants are faster, but move through air. Mantis shrimp are comparably fast and aquatic, but much larger. Jellyfish stinging cells are ejected with higher acceleration, but only once. “We take repeatability for granted in biology,” said Longo, a visiting assistant professor at Towson University and first author on the paper. “Lots of ultrafast movements are not repeatable, such as ballistic seed ejection by plants. Some of these seeds are going even faster than this amphipod and traveling an impressive distance, but they are one-off events.” Tiny Creatures Challenge Engineering Limits Repeatability is a big challenge for engineering, said Longo. Parts that move very fast often become disconnected, break, or have to be manually reloaded. This crustacean’s monster claw is a third of its body weight and closes 10,000 times faster than the blink of an eye. Credit: Patek Lab, Duke University “The fact that this movement is repeatable is marking an interesting boundary,” Longo said. “There appears to be a cutoff where you are going so fast that you inherently have to give up repeatability. These animals are showing how fast you can actually go without breaking.” “These organisms are doing things with capabilities that we currently cannot build. Engineered systems that can be used repeatedly are several orders of magnitude slower and bigger than these animals,” said Sheila Patek, a professor at Duke Biology and senior author on the paper. The potential behind ultrafast movements is so great that the Army is paying attention to these small animals. “Small organisms achieve incredible actuation authority with no adherence to the rules we use for engineering using motors, springs, and structures,” said Samuel Stanton, program manager, Army Research Office, an element of the U.S. Army Combat Capabilities Development Command’s Army Research Laboratory. “There is a myriad of organisms from which we can learn a great deal for future Army small robotics and this research team is discovering a whole new set of rules we should be following.” Evolution’s Ingenious Problem Solving “There is a lot that biology can tell us,” Longo said. “Evolution has had millions of years to come up with solutions to all sorts of problems that we can’t even articulate yet.” Just the size of a sunflower seed, the amphipod Dulichiella wields a giant claw that snaps shut 10,000 times faster than the blink of a human eye. Credit: Patek Lab – Duke University This discovery is surprising given that these amphipods are very common, being found all over the Eastern coast of North America. “The majority of biologists tend not to pay much attention to amphipods, because they are so small,” said Rich Palmer, a professor at the University of Alberta and co-author on the paper. “We would never have guessed that they make these ultra-fast movements.” Palmer had his attention drawn to these animals when colleagues mentioned in a casual conversation that certain amphipods made snapping noises. Intrigued, he suggested to Patek a trip to the Duke Marine Laboratory, in Beaufort, NC, in order to investigate these snaps further. To everyone’s surprise and delight, they found thousands of these ultra-fast animals right off the docks. “Hanging in debris, off a dock, in some junky algae, are creatures whose capabilities we didn’t even know existed,” says Patek. “This is what happens if you take a second look at a weird animal and just take the time to figure out what they are doing.” “You have to be curious, you have to be brave, and you can’t be afraid of wasting time,” said Palmer. “That is how amazing discoveries are made.” Reference: “Snaps of a tiny amphipod push the boundary of ultrafast, repeatable movement” by S.
