Credit: Taro Maeda Genome analysis reveals chloroplast acquisition without gene transfer in photosynthetic sea slugs. Plants, algae, and some bacteria are able to perform photosynthesis, which is the process of transforming sunlight energy into sugar. Animals are generally unable to use this process to acquire energy, but there are a few known exceptions to this. Some sea slugs take up chloroplasts from the algae that they consume into their cells. These chloroplasts retain their ability to perform photosynthetic activity within the animal cells for several months, and thus provide them with photosynthesis-derived nutrition. This process is called “kleptoplasty,” and it has attracted much attention due to its amazing uniqueness in making animals photosynthetic for over 50 years. A pressing question is how these sequestered chloroplasts retain their photosynthetic capability without algal nuclei. Since the genome of the algal nucleus encodes most of the proteins required for photosynthesis, chloroplasts isolated from algal cells instantly lose their photosynthetic capability. Nevertheless, algae-eating sea slugs retain this photosynthetic capability for months. There have been numerous debates about the mechanisms underlying the phenomenon of sequestered chloroplasts retaining photosynthetic capabilities over the long term. A widely accepted hypothesis accounting for kleptoplasty is the horizontal gene transfer of the photosynthesis genes from algae to sea slug. A team of researchers at the National Institute for Basic Biology (NIBB), in addition to collaborators from seven other Japanese institutions, have published the genome of the sea slug, Plakobranchus ocellatus type black, in eLife. “Since the sea slug is a non-model organism, its genome analysis was very tough in comparison to model organisms such as the mouse and the fruitfly. Furthermore, there was no high-quality genetic information for them. This situation consequently hindered the verification of the hypothesis of algae-derived horizontal gene transfer,” said Shuji Shigenobu, a genome scientist and professor at NIBB who is the corresponding author of the paper, “But we succeeded in accurately revealing the genome information of the sea slug”. Scientists are ready to settle the arguments concerning the horizontal transfer of algal genes to the animal nucleus based on newly unveiled genome data. “We looked at the genome very carefully, but we found no evidence of photosynthetic genes encoded on the sea slug genome, ” he said. “We are embarking upon a new challenge to answer the question: how does the sea slug retain this function without horizontal gene transfer?” said Taro Maeda, the first and co-corresponding author of the paper. “Our genome data also provides clues to this. We have found several candidate genes related to the long-term maintenance of photosynthetic activity. These genes related to protein metabolism, oxidative stress tolerance, and innate immunity should be subsequently highlighted in future studies.” The mechanisms underlying kleptoplasty are still elusive. Further understanding of this phenomenon may lead us to innovative biotechnologies, which, for example, could bestow photosynthetic abilities to other various animal cells in the future.

Credit: Gregory Urquiaga/UC Davis Network of wildlife rehabilitation organizations helps track emerging threats. From domoic acid poisoning in seabirds to canine distemper in raccoons, wildlife face a variety of threats and illnesses. Some of those same diseases make their way to humans and domestic animals in our increasingly shared environment. A new early detection surveillance system for wildlife helps identify unusual patterns of illness and death in near real-time by tapping into data from wildlife rehabilitation organizations across California. This system has the potential to expand nationally and globally. It was created by scientists at the University of California, Davis, School of Veterinary Medicine with partners at the California Department of Fish and Wildlife and the nonprofit Wild Neighbors Database Project. The Wildlife Morbidity and Mortality Event Alert System is described in a study published today in the journal Proceedings of the Royal Society B. “Human-induced disturbances are contributing to a wide range of threats — habitat loss, invasive species introductions, pollution, disease, wildfires,” said co-lead author Terra Kelly, a wildlife epidemiologist at the UC Davis One Health Institute and its Karen C. Drayer Wildlife Health Center within the School of Veterinary Medicine. “It speaks to the need for a system like this where we can better understand the threats facing wildlife populations and respond to them in a timely way so there’s less harm to wildlife.” Front-line responders for wildlife Wildlife rehabilitation workers are the front-line responders of the free-ranging animal world. They are the first to receive and tend to sick and injured wild animals. Their clinical reports carry a wealth of information that, when shared, can indicate broader patterns. Until recently, such clinical reports were stored primarily on paper or isolated computer files. In 2012, Wild Neighbors Database Project co-founders Devin Dombrowski and Rachel Avilla created the Wildlife Rehabilitation Medical Database, or WRMD, a free online tool now used by more than 950 rehabilitation organizations across 48 states and 19 countries to monitor patient care. Dombrowski and Avilla brought the tool to CDFW, which connected with long-standing partners at UC Davis to pilot an alert system using the database as its foundation. “I’m thrilled that WRMD is not only useful for thousands of wildlife rehabilitators but that the data collected by them is used for morbidity and mortality monitoring,” co-author Dombrowski said. “To witness the WMME Alert System identifying data anomalies and alerting investigators is incredible.” The CDFW is using the system to help identify and prioritize wildlife needs and conservation efforts. “The near real-time information this system provides has allowed us to quickly follow up with diagnostic testing to identify the problem,” said Krysta Rogers, senior environmental scientist at the CDFW’s Wildlife Health Laboratory. “This system also has been instrumental in determining the geographic range and severity of the threat.” How it works To test the system, the scientists analyzed 220,000 case records collected between early 2013 to late 2018 to establish thresholds for triggering alerts. The dataset included records from 453 different species, from the common to the rare.

Red areas indicate a high kernel density of cases. Credit: UC Davis/Proceedings from the Royal Society B The authors emphasize the alert system is pre-diagnostic. It alerts agencies to unusual patterns that may warrant further investigation to determine specific health threats. The system detected several key events, including large admissions of: Marine birds along the central and southern California coast in late spring 2016. Post-mortem examinations confirmed they were starving. Marine birds in April 2017. Domoic acid toxicity was later confirmed as the cause of death. Invasive Eurasian collared doves in 2016 with encephalitis and kidney disease. Investigations revealed pigeon paramyxovirus-1 as the cause of the event. This was the first detection of the virus emerging in Eurasian collared doves in this region of California. Rock pigeons in the San Francisco Bay Area in 2017 with an emerging parasite. Finches in 2016 and 2017 with seasonal conjunctivitis due to infection with Mycoplasma bacteria. Human connections Kelly notes that being able to monitor and rapidly detect such events is important for all species, humans included. For example, domoic acid intoxication is caused by harmful algal blooms, which are increasing in coastal and freshwater systems and threaten both wildlife and human health. Another example is West Nile virus, where bird deaths can serve as a sensitive indicator for risk to domestic animals and people. The alert system is a complementary, inexpensive and efficient tool to add to state wildlife agencies’ toolbox of surveillance efforts. It combines machine-learning algorithms, natural language processing, and statistical methods used for classifying cases and establishing thresholds for alerts with the ecology and distribution of wildlife within California, said co-leading author Pranav Pandit, a researcher in the UC Davis One Health Institute and its EpiCenter for Disease Dynamics. “The wildlife rehabilitation organizations’ data is making such valuable contributions,” Pandit said. “That’s all coming together in this highly adaptable surveillance system.” Reference: “Early detection of wildlife morbidity and mortality through an event-based surveillance system” by Terra R.

The study was funded by a State Wildlife Grant from CDFW. Scientists have discovered that elephant seals only average two hours of sleep per day when they are at sea on long foraging trips, with short naps occurring during deep, 30-minute dives. The study, led by Jessica Kendall-Bar at UC Santa Cruz, is the first to record brain activity in a wild marine mammal, shedding light on their unique sleep habits. Elephant seals are vulnerable to predators at the ocean surface, so they spend minimal time breathing there and instead fall into a deep slumber during their dives in deeper waters. Brainwave patterns show elephant seals take short naps while holding their breath on deep dives, averaging just 2 hours of sleep per day while at sea. For the first time, scientists have recorded brain activity in a free-ranging, wild marine mammal, revealing the sleep habits of elephant seals during the months they spend at sea. The new findings, published on April 20 in the journal Science, show that while elephant seals may spend 10 hours a day sleeping on the beach during the breeding season, they average just 2 hours of sleep per day when they are at sea on months-long foraging trips. They sleep for about 10 minutes at a time during deep, 30-minute dives, often spiraling downward while fast asleep, and sometimes lying motionless on the seafloor. First author Jessica Kendall-Bar led the study as a University of California, Santa Cruz (UCSC) graduate student working with Daniel Costa and Terrie Williams, both professors of ecology and evolutionary biology at UCSC. Elephant seals sleep about 10 hours a day on the beach, but during months-long foraging trips at sea they average just 2 hours of sleep per day.

Costa’s lab has led the UCSC elephant seal research program at Año Nuevo Reserve for over 25 years, using increasingly sophisticated tags to track the movements and diving behavior of the seals during their foraging migrations, when they head out into the North Pacific Ocean for as long as 8 months. “The dive records show that they are constantly diving, so we thought they must be sleeping during what we call drift dives, when they stop swimming and slowly sink, but we really didn’t know,” Costa said. “Now we’re finally able to say they’re definitely sleeping during those dives, and we also found that they’re not sleeping very much overall compared to other mammals.” Data-driven animation showing the phases of a sleeping dive to 263 meters. Credit: Animation by Jessica Kendall-Bar In fact, during their months at sea, elephant seals rival the record for the least sleep among all mammals, currently held by African elephants, which appear to sleep just two hours per day based on their movement patterns. “Elephant seals are unusual in that they switch between getting a lot of sleep when they’re on land, over 10 hours a day, and two hours or less when they’re at sea,” said Kendall-Bar, who is currently a postdoctoral fellow at University of California, San Diego’s Scripps Institution of Oceanography. Safe Slumber in the Depths Elephant seals are most vulnerable to predators such as sharks and killer whales when they are at the surface in the open ocean, so they only spend a minute or two breathing at the surface in between dives. “They’re able to hold their breath for a long time, so they can go into a deep slumber on these dives deep below the surface where it’s safe,” Kendall-Bar said. Cetaceans (whales and dolphins) and otariids (fur seals and sea lions) keep one side of their brains awake while the other is asleep (unihemispheric sleep). In most other mammals, including phocids (true seals) and humans, both hemispheres of the brain are asleep at the same time. Credit: Graphic by Jessica Kendall-Bar Kendall-Bar developed a system that can reliably record brain activity (as an electroencephalogram or EEG) in wild elephant seals during their normal diving behavior at sea. With a neoprene headcap to secure the EEG sensors and a small data logger to record the signals, the system can be recovered when the animals return to the beach at Año Nuevo. “We used the same sensors you’d use for a human sleep study at a sleep clinic and a removable, flexible adhesive to attach the headcap so that water couldn’t get in and disrupt the signals,” Kendall-Bar said. In addition to the EEG system, the seals carried time-depth recorders, accelerometers, and other instruments that allowed the researchers to track the seals’ movements along with the corresponding brain activity. The recordings show diving seals going into the deep sleep stage known as slow-wave sleep while maintaining a controlled glide downward, then transitioning into rapid-eye-movement (REM) sleep, when sleep paralysis causes them to turn upside down and drift downwards in a “sleep spiral.” “They go into slow-wave sleep and maintain their body posture for several minutes before they transition into REM sleep, when they lose postural control and turn upside down,” Kendall-Bar said. At the depths at which this happens, the seals are usually negatively buoyant and continue to fall passively in a corkscrew spiral “like a falling leaf,” Williams said. In shallower waters over the continental shelf, elephant seals sometimes sleep while resting on the seafloor. When elephant seals go into rapid-eye-movement (REM) sleep during deep dives, sleep paralysis causes them to turn upside down and drift downwards in a “sleep spiral.” This data-driven graphic shows sleeping postures every 20 seconds, with accompanying 30-second segments of EEG traces in the background. Credit: Graphic by Jessica Kendall-Bar Insights into Seal Behavior and Decision-Making “It doesn’t seem possible that they would truly go into paralytic REM sleep during a dive, but it tells us something about the decision-making processes of these seals to see where in the water column they feel safe enough to go to sleep,” said Williams, who directs the Comparative Neurophysiology Lab at UCSC. In developing the new EEG instrument, Kendall-Bar first deployed it on elephant seals housed temporarily in the marine mammal facilities at UCSC’s Long Marine Laboratory. The next step was to deploy it on animals in the elephant seal colony at Año Nuevo Reserve north of Santa Cruz, where researchers could observe the animals on the beach. “I spent a lot of time watching sleeping seals,” Kendall-Bar said. “Our team monitored instrumented seals to make sure they were able to reintegrate with the colony and were behaving naturally.” Some of those seals took short excursions into the water, but to observe diving behavior the researchers used a translocation procedure developed by Costa’s lab. Juvenile female elephant seals outfitted with the EEG sensors and trackers were transported from Año Nuevo to Monterey and released on a beach at the southern end of Monterey Bay. Over the next few days, the animals would swim back to Año Nuevo across the deep Monterey Canyon, where their dive behavior is very similar to that seen during much longer foraging trips in the open ocean. With data on brain activity and dive behavior from 13 juvenile female elephant seals, including a total of 104 sleep dives, Kendall-Bar developed a highly accurate algorithm for identifying periods of sleep based on the dive data alone. This enabled her to estimate sleep quotas for 334 adult seals using dive data recorded over several months during their foraging trips. “Because of the dataset that Dan Costa has curated over 25 years of working with elephant seals at Año Nuevo, I was able to extrapolate our results to over 300 animals and get a population-level look at sleep behavior,” said Kendall-Bar, who now plans to use similar methods to study brain activity in other species of seals and sea lions and in human freedivers. Williams called Kendall-Bar’s work on the project a tour de force. “It’s an amazing feat to pull this off,” she said. “She developed an EEG system to work on an animal that’s diving several hundred meters in the ocean. Then she uses the data to create data-driven animations so we can really visualize what the animal is doing as it dives through the water column.” The results may be helpful for conservation efforts by revealing a “sleepscape” of preferred resting areas, Williams said. “Normally, we’re concerned about protecting the areas where animals go to feed, but perhaps the places where they sleep are as important as any other critical habitat,” she said.
