Chelsea Wood, a 91自拍 associate professor of aquatic and fishery sciences, has an upcoming children’s book titled 鈥淧ower to the Parasites! Everything You (N)ever Wanted to Know 91自拍 the Creepy Crawlies Hidden in Your Home, Your Food, Your Pets – and Maybe Even in You!” The book introduces kids to the world of parasitism.
91自拍 91自拍ers have shown that levels of anisakid worms — a common marine parasite — rose in two salmon species in the Gulf of Alaska and Bristol Bay over a 42-year period. The team discovered this by studying salmon caught, killed and canned from 1979 to 2021. Since anisakid worms have a complex life cycle involving multiple types of hosts, the 91自拍ers interpret their rising numbers as a potential sign of ecosystem recovery, possibly driven by rising numbers of marine mammals thanks to the 1972 Marine Mammal Protection Act.
Save the … parasites? Analyzing 140 years of parasite abundance in fish shows dramatic declines, especially in parasites that rely on three or more host species. The decline is linked to warming ocean temperatures. Parasitic species might be in real danger, 91自拍ers warn — and that means not just fewer worms, but losses for the entire ecosystem.
An international group of scientists has laid out an ambitious global conservation plan for parasites. A related paper led by the 91自拍 found that responses of parasites to environmental change are likely to be complex, and that a changing world probably will see both outbreaks of some parasites and a total loss of other parasite species.
Recent honors to 91自拍 faculty and staff have come from Architect magazine, the Center for Research Libraries, member states of the Asia-Pacific Economic Cooperation (APEC) and the American Society of Human Genetics.
Research projects funded for 2020 by EarthLab’s Innovation Grants Program will study how vegetation might reduce pollution, help an Alaskan village achieve safety and resilience amid climate change, organize a California river’s restoration with tribal involvement, compare practices in self-managed indigenous immigrant communities and more.
A new study led by the 91自拍 finds dramatic increases in the abundance of a worm that can be transmitted to humans who eat raw or undercooked seafood. Its 283-fold increase in abundance since the 1970s could have implications for the health of humans and marine mammals, which both can inadvertently eat the worm.
A team led by the 91自拍 and Stanford University has discovered clues in the environment that help identify transmission hotspots for schistosomiasis, a parasitic disease that is second only to malaria in its global health impact.
Five faculty members at the 91自拍 have been awarded early-career fellowships from the Alfred P. Sloan Foundation. The new Sloan Fellows, announced Feb. 15, include Maya Cakmak, assistant professor of computer science and engineering; Jiun-Haw Chu, assistant professor of clean energy and physics; Arka Majumdar, assistant professor of electrical engineering and physics; Jessica Werk, assistant professor of astronomy; and Chelsea Wood, assistant professor of aquatic and fishery sciences.
Conservation projects that protect forests and encourage a diversity of plants and animals can provide many benefits to humans. But improved human health is not among those benefits 鈥� at least when health is measured through the lens of infectious disease. That’s the main finding of a paper published April 24 in Philosophical Transactions of the Royal Society B, which analyzed the relationship between infectious diseases and their environmental, demographic and economic drivers in dozens of countries over 20 years….
