A recent study showcases how Florida carpenter ants perform sophisticated surgical treatments, including wound cleaning and amputation, to aid their injured nestmates. This unique behavior, which varies depending on the type of injury, highlights the advanced medical systems in non-human species, demonstrating survival rates significantly higher than untreated injuries. Credit: Danny Buffat Research on Florida carpenter ants reveals they employ advanced medical techniques like amputation and wound cleaning based on injury type, significantly enhancing survival rates compared to untreated cases. A new study published in Current Biology reveals that humans are not the only ones who save lives through surgery. Researchers have shown how Florida carpenter ants, a common, brown species native to its namesake, selectively treat the wounded limbs of fellow nestmates—either by wound cleaning or amputation. When experimentally testing the effectiveness of these “treatments,” not only did they aid in recovery, but the research team found the ants’ choice of care catered to the type of injury presented to them. First author Erik Frank, a behavioral ecologist from the University of Würzburg, said: “When we’re talking about amputation behavior, this is literally the only case in which a sophisticated and systematic amputation of an individual by another member of its species occurs in the animal Kingdom.” Understanding Wound Care in Ants Wound care among ants is not an entirely new phenomenon. A study published in 2023 discovered that a different group of ants, Megaponera analis, use a special gland to inoculate injuries with antimicrobial compounds meant to quell possible infections. What makes Florida carpenter ants (Camponotus floridanus) stand out is that because they have no such gland, they appear to be using only mechanical means to treat their nestmates. The researchers found that this mechanical care involves one of two routes. The ants would either perform wound cleaning with just their mouthparts or perform a cleaning followed by the full amputation of the leg. To select which route they take, the ants appear to assess the type of injury to make informed adjustments on how best to treat. Detailed Analysis of Injury Treatments In this study, two types of leg injuries were analyzed, lacerations on the femur and those on the ankle-like tibia. All femur injuries were accompanied by initial cleaning of the cut by a nestmate, followed by a nestmate chewing off the leg entirely. In contrast, tibia injuries only received the mouth cleaning. In both cases, the intervention resulted in ants with experimentally infected wounds having a much greater survival rate. “Femur injuries, where they always amputated the leg, had a success rate around 90% or 95%. And for the tibia, where they did not amputate, it still achieved about the survival rate of 75%,” says Frank. This is in contrast to the less than 40% and 15% survival rate for unattended infected femur and tibia abrasions, respectively. Implications of Different Injury Locations The researchers hypothesized that the preferred path of wound care could be related to the risk of infection from the wound site. Micro-CT scans of the femur showed it is largely composed of muscle tissue, suggesting it plays a functional role in pumping blood, referred to as hemolymph, from the leg into the main body. With an injury to the femur, the muscles become compromised, reducing their ability to circulate potentially bacteria-laden blood. The tibia, on the other hand, has little muscle tissue and thus little involvement in blood circulation. “In tibia injuries, the flow of the hemolymph was less impeded, meaning bacteria could enter the body faster. While in femur injuries the speed of the blood circulation in the leg was slowed down,” says Frank. You may expect, then, that if tibia damage results in faster infections, amputating the full leg would be most appropriate, but the opposite is observed. It turns out the speed at which the ants can amputate a leg makes a difference. An ant-assisted amputation takes at least 40 minutes to complete. Experimental testing demonstrated that with tibia injuries if the leg was not immediately removed post-infection, the ant would not survive. “Thus, because they are unable to cut the leg sufficiently quickly to prevent the spread of harmful bacteria, ants try to limit the probability of lethal infection by spending more time cleaning the tibia wound,” remarks senior author and evolutionary biologist Laurent Keller of the University of Lausanne. Comparison with Human Medical Practices “The fact that the ants are able to diagnose a wound, see if it’s infected or sterile, and treat it accordingly over long periods of time by other individuals—the only medical system that can rival that would be the human one,” Frank says. Considering the sophisticated nature of these behaviors, a reasonable next thought would be how these ants are capable of such precise care. “It’s really all innate behavior,” says Keller. “Ant behaviors change based on the age of an individual, but there is very little evidence of any learning.” Further Research and Implications Now the lab team is running similar experiments in other Camponotus species to see just how conserved this behavior is and begin to unpack whether all ant species without the special antimicrobial (metapleural) gland also perform amputation. Also, since the ant receiving care allows for the slow removal of a limb while conscious, this calls for further exploration into our understanding of pain in ant societies. “When you look at the videos where you have the ant presenting the injured leg and letting the other one bite off completely voluntarily, and then present the newly made wound so another one can finish cleaning process—this level of innate cooperation to me is quite striking,” says Frank.

Ahmerkamp/Max Planck Institute for Marine Microbiology Scientists have discovered a remarkable new form of symbiosis — a bacterium that lives inside a single-celled organism (a ciliate) and provides it with energy. Unlike mitochondria, which use oxygen, this microbe powers its host by breathing nitrate. Initially found in a freshwater lake, researchers set out to determine how widespread these microbes are. To their surprise, they uncovered them in diverse environments worldwide, from lakes and groundwater to even wastewater. This discovery challenges our understanding of microbial partnerships and reveals how these tiny organisms play a hidden yet significant role in global ecosystems. A New Symbiotic Discovery In 2021, scientists at the Max Planck Institute for Marine Microbiology in Bremen, Germany, made a remarkable discovery: a unique bacterium that lives inside a ciliate — a single-celled eukaryote — and provides it with energy. This symbiotic relationship is similar to the role mitochondria play in cells, but with one major difference: instead of using oxygen, this endosymbiont generates energy by respiring nitrate. To better understand the distribution and diversity of these unusual microbes, the researchers in Bremen expanded their study. Now the re­search­ers from Bre­men set out to learn more about the en­vir­on­mental dis­tri­bu­tion and di­versity of these pe­cu­liar sym­bionts. “After our ini­tial dis­cov­ery of this sym­biont in a fresh­wa­ter lake, we wondered how com­mon these or­gan­isms are in nature,” explains Jana Milucka from the Max Planck In­sti­tute for Mar­ine Mi­cro­bi­o­logy. “Are they ex­tremely rare and there­fore eluded de­tec­tion so long? Or do they ex­ist else­where and if so, what are their meta­bolic ca­pa­cit­ies?” A Global Inhabitant To find answers, the scientists searched massive public sequencing databases containing genetic data from a wide range of environmental samples. Their findings were surprising: these symbionts appeared in about 1,000 different datasets. “We were sur­prised how ubi­quit­ous they are. We could find them on every in­hab­ited con­tin­ent,” says Milucka. “Moreover, we learned that they can live not only in lakes and other fresh­wa­ter hab­it­ats but also in ground­wa­ter and even wastewa­ter.” Meet the Family: New Members Do New Tricks The sci­ent­ists dis­covered not only the ori­ginal sym­biont in these data­sets, but also some new close re­l­at­ives. “We ended up identi­fy­ing four new spe­cies, two of which ac­tu­ally con­sti­tuted a new genus. Be­cause this new genus of sym­bionts likely has a sim­ilar role as the ori­gin­ally dis­covered Azoamicus (name mean­ing “ni­tro­gen friend”), we named the new genus Azoso­cius (“ni­tro­gen as­so­ci­ate”), ex­plains first-au­thor Daan Speth. “Lucky for us, one of the new Azoso­cius spe­cies was re­trieved not too far from Bre­men, from a ground­wa­ter sample in Hainich, Ger­many.” Evolving Capabilities: A Surprising Oxygen Connection Now the sci­ent­ists wanted to dig deeper into the life of these new spe­cies. Thanks to a col­lab­or­a­tion with Kirsten Küsel and Will Over­holt from the Friedrich Schiller Uni­versity in Jena, Ger­many, who ini­tially col­lec­ted the Hainich samples, they were able to ac­cess the sampling site and look into meta­tran­scrip­tomic data, i.e. data de­scrib­ing the gene ex­pres­sion in the sample and in­dic­at­ing mi­cro­bial activ­ity. “Here, we were in for an­other sur­prise – these res­pir­at­ory sym­bionts can do new tricks,” Speth con­tin­ues. Un­like the ori­ginal sym­biont spe­cies, which can only per­form an­aer­obic res­pir­a­tion (i.e. de­ni­tri­fic­a­tion), all new sym­biont spe­cies ac­tu­ally en­code a ter­minal ox­i­dase – an en­zyme that en­ables them to also respire oxy­gen in ad­di­tion to ni­tro­gen. “This can ex­plain why we find these sym­bionts also in en­vir­on­ments that are fully or par­tially oxic.” Evolutionary and Ecological Implications These res­ults, now presen­ted in the journal Nature Communications, an­swer the sci­ent­ists’ open ques­tions re­gard­ing the sym­biont’s biogeo­graphy. “Thanks to the dis­cov­ery of these new spe­cies, we can now also start think­ing more about their evol­u­tion,” Milucka looks ahead. “We can hope­fully un­der­stand bet­ter how these be­ne­fi­cial sym­bi­oses be­gin and how they evolve over time.” Moreover, there is an eco­lo­gical as­pect to this re­search: “By per­form­ing de­ni­tri­fic­a­tion, this sym­bi­osis im­pacts the ni­tro­gen cycle of their re­spect­ive hab­itat and has the po­ten­tial to re­move nu­tri­ents, such as ni­tro­gen ox­ides, as well as pro­duce green­house gases, such as ni­trous ox­ide,” adds Speth. Marvels of Microbial Symbiosis And last but not least, there is the simple ap­pre­ci­ation of the in­triguing world of mi­crobes. “This or­gan­ism is a mar­vel of nature,” Milucka en­thuses. “Prot­ists are cap­able of such as­ton­ish­ing meta­bolic in­nov­a­tions, of­ten be­cause they so read­ily jump into re­la­tion­ships with proka­ryotes. To me, this is just fas­cin­at­ing. When it comes to un­der­stand­ing the evol­u­tion of eu­k­a­ryotes, these or­gan­isms are an im­port­ant piece of the puzzle.” Reference: “Genetic potential for aerobic respiration and denitrification in globally distributed respiratory endosymbionts” by Daan R.

In a recent study, researchers used a new geochemical technique on fossil teeth to confirm that the extinct Megalodon shark was warm-blooded. This warmth, which facilitated the creature’s gigantism, is thought to have increased the metabolic needs of the Megalodon, potentially contributing to its extinction. The research underlines the vulnerability of large marine apex predators to environmental changes and stresses the importance of conserving modern shark species. A new study shows that the gigantic Megalodon, or megatooth shark, was warm-blooded. This latest research on the Megalodon, which lived in the world’s oceans from 23 million to 3.6 million years ago and measured about 50 feet in length, appears in the peer-reviewed journal Proceedings of the National Academy of Sciences. The study, conceived of and led by Michael Griffiths and Martin Becker, both professors of environmental science at William Paterson University, used fossil teeth to determine that the Megalodon’s body temperature was much higher than previously thought. Also involved in the study were Kenshu Shimada, a paleobiologist at DePaul University in Chicago, Robert Eagle at the University of California at Los Angeles, and Sora Kim at the University of California at Merced. Other coauthors of the paper include researchers from Florida Gulf Coast University in Florida, Princeton University in New Jersey, and Goethe University Frankfurt in Germany. The extinct megatooth shark Otodus megalodon had regional endothermy (partial warm-bloodedness) physiology based on geochemical samples taken from fossilized teeth. Credit: Alex Boersma/PNAS Previous studies have suggested that the Megalodon (formally called Otodus megalodon) was likely warm-blooded, or more precisely regionally endothermic, just like some modern-day sharks. However, those findings were based on pure inference, the researchers say. Their study provides the first empirical evidence of warm-bloodedness in the extinct shark. The research team used a novel geochemical technique, involving clumped isotope thermometry and phosphate oxygen isotope thermometry, to test the “Megalodon Endothermy Hypothesis.” “Studies using these methods have shown them to be particularly useful in inferring the thermo-physiologies of fossil vertebrates of ‘unknown’ metabolic origins by comparing their body temperature with that of co-occurring fossils of ‘known’ metabolisms,” explains Griffiths, of William Paterson University, the lead author of the study. Clumped isotope thermometry is based on the thermodynamic preference for two or more ‘heavier’ isotopes of a particular element (due to extra neutrons in the nucleus), such as carbon-13 and oxygen-18, to form bonds in a mineral lattice based on the mineralization temperatures. The degree to which these isotopes bond or ‘clump’ together can then reveal the temperature at which the mineral formed. Phosphate oxygen isotope thermometry is based on the principle that the ratio of the stable oxygen isotopes, oxygen-18 and oxygen-16, in phosphate minerals depends on the temperature of the body water from which they formed. An upper tooth from a megalodon (right) dwarfs that of a white shark. Credit: Harry Maisch/Florida Gulf Coast University The new study found that Megalodon had body temperatures significantly higher than sharks considered cold-blooded or ectothermic, consistent with the fossil shark having a degree of internal heat production as modern warm-blooded animals do. Among the modern-day sharks with regional endothermy is a group that includes mako and great white sharks with the previously reported average body temperature ranging from 22.0 to 26.6˚C, which may be 10 to 21˚C higher than ambient ocean temperature. The new study suggests Megalodon had an overall average body temperature of about 27˚C. Otodus megalodon has a rich fossil record, but its biology remains poorly understood, like most other extinct sharks, because no complete skeleton of the cartilaginous fish is known in the fossil record. Luckily, its abundant teeth remain and can serve as a door to the past. “Otodus megalodon was one of the largest carnivores that ever existed and deciphering the biology of the prehistoric shark offers crucial clues about the ecological and evolutionary roles large carnivores have played on marine ecosystems through geologic time,” says Shimada. The ability of Otodus megalodon to regulate body temperature is evolutionarily profound because the evolution of warm-bloodedness is thought to have also acted as a key driver for its gigantism. Previous geochemical investigations by Griffiths, Becker, and their colleagues have suggested that Otodus megalodon was a significant apex predator, residing at the very top of the marine food chain. The high metabolic needs associated with maintaining warm-bloodedness may have contributed to the species’ extinction, the researchers say. “Because megalodon went extinct around the time of extreme changes in climate and sea-level, which impacted the distribution of and the type of prey, our new study sheds light on the vulnerability of large marine apex predators, such as the great white shark, to stressors such as climate change,” says Griffiths, highlighting the need for conservation efforts to protect modern shark species.
