During their migration, reed warblers use magnetic information as a ‘stop sign’ – with magnetic inclination in particular telling the birds that they have arrived at their destination. Credit: Thomas Miller A new study published on January 27, 2022) in Science Magazine has shed light on how birds navigate back to their breeding site after flying across two continents. Magnetic information seems to play a key role. The study, part of an international collaboration led by researchers at the University of Oxford and including scientists from the University of Oldenburg, suggests that information extracted from the Earth’s magnetic field tells birds where and when to stop migrating. This trick allows them to precisely target the same breeding site year-on-year from thousands of kilometers away. How birds sense the Earth’s magnetic field has been the subject of intense research. Birds might even ‘see’ magnetic field lines, and possibly use this ability to both determine the direction they’re facing in and where they are.   Dr. Joe Wynn, formerly of the University of Oxford and now a researcher at the Institute for Avian Research, Germany, said: “Whilst we know an increasing amount about how birds inherit migratory information from their parents, how they return to the same site year-on-year with pinpoint accuracy has remained elusive. It’s quite exciting, therefore, that we’ve been able to find evidence that magnetic cues could be used by songbirds trying to re-locate their homes.” He started developing the idea for the study during a stay as a guest scientist in the research group of biologist Prof. Dr. Henrik Mouritsen at the University of Oldenburg. Mouritsen was also involved in data analysis for the study. You Have Arrived at Your Destination The team analyzed data from nearly 18,000 reed warblers to investigate whether the birds used the Earth’s magnetic field when finding their breeding site. Reed warblers are tiny songbirds that fly across the Sahara Desert each year to spend the summer in Europe. They found that, as the magnetic field of Earth moved slightly, the sites to which birds returned moved with it, suggesting that birds homed to a moving magnetic target. Birds appeared to use magnetic information as a ‘stop sign’, with magnetic inclination in particular telling birds that they had arrived at their breeding location. Reed warblers return to their breeding grounds in Europe after a journey of several thousand kilometers. The work utilized ‘ringing’ data. For nearly a century, uniquely numbered metal rings have been attached to the legs of birds from across Europe. Dr. Wynn added that “Ringing data are a fantastic way to answer questions about migration, simply because they’ve been gathered for so many years across a very large area…and when looking at where birds and ringed and then recovered, it seems that reed warblers use a single magnetic coordinate a bit like a ‘stop sign’; when they reach the right magnetic field value, they stop migrating.” Why Use the Magnetic Field To Inform Return Migration? Dr. Wynn explains that “Magnetic information seems to be pretty stable, meaning the magnetic field doesn’t change very much in a given location year-on-year. Aiming for a specific magnetic value during migration might make sense then, and the cue we think birds are using, inclination, appears the most stable aspect of the magnetic field. We think this gives the birds the best chance of making it back to the breeding site.” In conclusion, Dr. Wynn said: “The trans-continental migration of birds that weigh less than a teaspoon is remarkable for so many reasons, but the ability to precisely pinpoint the breeding site from half the world away is perhaps the most extraordinary aspect of all. That we can investigate this using data gathered by scientists and bird-watchers alike is extremely exciting, and we hope that this use of citizen science data inspires others to go out, watch birds, and get excited about science more generally.” A new study published today in Science Magazine has shed light on how birds navigate back to their breeding site after flying across 2 continents.

The cold wave study took place around the ‘Los Amigos’ research station in the Peruvian Amazon lowlands. The station is reached after a 14-hour boat trip on the Madre de Dios River. Credit: Kim Lea Holzmann / University of Wuerzburg A rare Amazon cold wave dropped temperatures drastically, prompting researchers to study its effects on wildlife. While most animals adapted, some insects showed vulnerability, raising concerns about future climate impacts. Anyone conducting research in the tropical rainforest does not necessarily carry a winter jacket and warm socks. After all, this region is known for its consistently pleasant temperatures. However, as Kim Lea Holzmann and Pedro Alonso-Alonso discovered firsthand, this is not always the case. Both researchers, who are pursuing their doctoral theses at the University of Würzburg’s Biocentre, spent nearly all of 2023 in the Amazon region of southern Peru studying biodiversity. On June 13, an unexpected cold spell caused temperatures to plummet from an average of 23.9 to 10.5 degrees Celsius. The chilly period lasted for nearly a week. ‘A year before, we had already experienced a day when it was only 18 degrees,’ says Kim Lea Holzmann. But such severe and prolonged cold seemed strange to them. The local field assistants, on the other hand, were not really surprised. They explained to the Würzburg team that cold spells lasting several days are not that rare in the Amazon. First Study on Cold Waves and Wildlife The research team spontaneously decided to seize the opportunity: How would the wildlife react to the cold snap? That was the research question. ‘So far, there have only been studies on how cold waves affect agriculture in the Amazon region. We have now presented the first-ever study on how they affect wild animal communities in the lowlands of the Amazon,’ says the doctoral student. The results have been published in the journal Biology Letters. The Würzburg researchers photographed these mammals in the southern Peruvian rainforest using camera traps (clockwise from top left): a jaguar, a paca, an agouti, and a peccary. Credit: Kim Lea Holzmann / University of Wuerzburg Conclusion: All in all, the insects and mammals studied appear to have coped well with the cold wave- with one exception in the case of insects. In addition, the cold tolerance of a quarter of the insects analyzed was almost exhausted by the low temperatures measured. Certain species could face problems if the cold waves become even more severe in the future. This is quite conceivable in the light of climate change. Focus on Insects and Mammals For the study, the research team was able to draw on data that it had already collected in 2022 for its biodiversity studies. It had recorded the biomass of flying and ground-dwelling insects using various insect traps. Twelve camera traps were also used to document the activity of jaguars, tapirs, peccaries, and other wild mammals. The researchers then collected all this data again during the cold spell and again a few months after it ended. During the cold wave, the biomass and activity of all insects fell sharply. In the months that followed, however, there was a complete recovery. Only in the group of dung beetles the biomass remained low. They are apparently more sensitive to the cold than other insect groups. The researchers also determined the cold tolerance of various insects by cooling them down in a thermostat until they lost mobility. This showed that most insects can withstand even lower temperatures than those that occurred in June 2023. However, this is not the case for 25 percent of the insects studied: ‘They go into torpor when the temperature is just 0.62 degrees Celsius below the during the cold wave measured 10.5 degrees,’ says Pedro Alonso-Alonso. Insects are completely immobile during torpor – if this state lasts longer, it is likely to have a negative impact on their ability to survive, according to the researchers. Cold Caused Unusual Calm in the Rainforest Mammals also did not appear in front of the camera traps as often in the cold. Unlike insects, they can keep their body temperature constant. ‘To do this, they need more energy during the cold phase, which they presumably save by reducing their physical activity,’ says Kim Lea Holzmann. Typical animals in the lowland rainforest of the Amazon: On the left, the palm-sized dung beetle Coprophanaeus lancifer, which appears to be sensitive to low temperatures. On the right, the Brazilian wandering spider Phoneutria boliviensis, which also grows to the size of a palm. The spider can often be seen at night, but during the cold wave it was nowhere to be seen. Credit: Kim Lea Holzmann / University of Wuerzburg After the cold wave, the mammals observed returned to their usual routines. ‘We didn’t collect data on birds, reptiles, and amphibians, but our subjective observations show that these animal groups were also less active than usual. During the cold wave, the rainforest was unusually quiet.’ Background: Cold Waves in the Amazon Rainforest Cold waves, in which temperatures drop sharply for at least three consecutive days, occur relatively frequently in the Amazon Basin. Between 1980 and 2017, 67 cold spells were identified there, some of which lasted up to eight days. A clear cycle for their occurrence is not yet known. In most cases, the cold waves are caused by cold air fronts traveling northwards from Antarctica, parallel to the Andes and the Brazilian highlands.

Credit: Freshwater and Marine Image Bank/University of Washington Libraries Using canned salmon, scientists studied anisakid roundworms to assess changes in Alaskan marine ecosystems over four decades, revealing insights into ecological health and the impact of environmental legislation. Alaskan waters are a critical fishery for salmon. Complex marine food webs underlie and sustain this fishery, and scientists want to know how climate change is reshaping them. But finding samples from the past isn’t easy. “We have to really open our minds and get creative about what can act as an ecological data source,” said Natalie Mastick, currently a postdoctoral researcher at the Peabody Museum of Natural History at Yale University. Innovative Approach to Marine Ecology As a doctoral student at the University of Washington in Seattle, Mastick investigated Alaskan marine food webs using a decidedly unorthodox source: old cans of salmon. The cans contained fillets from four salmon species, all caught over a 42-year period in the Gulf of Alaska and Bristol Bay. Mastick and her colleagues dissected the preserved fillets from 178 cans and counted the number of anisakid roundworms — a common, tiny marine parasite — within the flesh. The parasites had been killed during the canning process and, if eaten, would have posed no danger to a human consumer. But counting anisakids is one way to gauge how well a marine ecosystem is doing. A highly degraded anisakid parasite recovered from canned salmon. Scale bar is 0.5 millimeters. Credit: Natalie Mastick/University of Washington “Everyone assumes that worms in your salmon is a sign that things have gone awry,” said Chelsea Wood, a UW associate professor of aquatic and fishery sciences. “But the anisakid life cycle integrates many components of the food web. I see their presence as a signal that the fish on your plate came from a healthy ecosystem.” The research team reports in a paper published on April 4 in Ecology & Evolution that anisakid worm levels rose for chum and pink salmon from 1979 to 2021, and stayed the same for coho and sockeye salmon. Implications and Future Research “Anisakids have a complex life cycle that requires many types of hosts,” said Mastick, who is lead author on the paper. “Seeing their numbers rise over time, as we did with pink and chum salmon, indicates that these parasites were able to find all the right hosts and reproduce. That could indicate a stable or recovering ecosystem, with enough of the right hosts for anisakids.” Anisakids start out living freely in the ocean. They enter food webs when eaten by small marine invertebrates, such as krill. As that initial host gets eaten by another species, the worms come along for the ride. Infected krill, for example, could be eaten by a small fish, which in turn gets eaten by a larger fish, like salmon. This cycle continues until the anisakids end up in the intestine of a marine mammal, where they reproduce. The eggs are excreted back into the ocean to hatch and begin the cycle again with a new generation. “If a host is not present — marine mammals, for example — anisakids can’t complete their life cycle and their numbers will drop,” said Wood, who is senior author on the paper. A photo of an anisakid worm — circled in red — in a canned salmon fillet. Credit: Natalie Mastick/University of Washington People cannot serve as hosts for anisakids. Consuming them in fully cooked fish poses little danger, because the worms are dead. But anisakids — also known as “sushi worms” or “sushi parasites” — can cause symptoms similar to food poisoning or a rare condition called anisakiasis if ingested alive in raw or undercooked fish. The Seafood Products Association, a Seattle-based trade group, donated the cans of salmon to Wood and her team. The association no longer needed the cans, which had been set aside each year for quality control purposes. Mastick and co-author Rachel Welicky, an assistant professor at Neumann University in Pennsylvania, experimented with different methods to dissect the canned fillets and look for anisakids. The worms are about a centimeter (0.4 inches) long and tend to coil up in the fish muscle. They found that pulling the fillets apart with forceps allowed the team to count worm corpses accurately with the aid of a dissecting microscope. There are several explanations for the rise of anisakid levels in pink and chum salmon. In 1972, Congress passed the Marine Mammal Protection Act, which has allowed populations of seals, sea lions, orcas, and other marine mammals to recover following years of decline. “Anisakids can only reproduce in the intestines of a marine mammal, so this could be a sign that, over our study period — from 1979 to 2021 — anisakid levels were rising because of more opportunities to reproduce,” said Mastick. Other possible explanations include warming temperatures or positive impacts of the Clean Water Act, Mastick added. The stable anisakid levels in coho and sockeye are harder to interpret because there are dozens of anisakid species, each with their own series of invertebrate, fish, and mammal hosts. While the canning process left the tough anisakid exterior intact, it destroyed the softer parts of their anatomy that would have allowed identification of individual species. Mastick and Wood believe this approach could be used to look at parasite levels in other canned fish, like sardines. They also hope this project will help make new, serendipitous connections that could fuel additional insight into ecosystems of the past. “This study came about because people heard about our research through the grapevine,” said Wood. “We can only get these insights into ecosystems of the past by networking and making the connections to discover untapped sources of historical data.” Reference: “Opening a can of worms: Archived canned fish fillets reveal 40 years of change in parasite burden for four Alaskan salmon species” by Natalie Mastick, Rachel Welicky, Aspen Katla, Bruce Odegaard, Virginia Ng and Chelsea L.
