91探花 biologist Samuel Wasser uses DNA evidence to trace the origin of illegal ivory and help police an international trade that is decimating African elephant populations. New results show that over the past decade, ivory has largely come from just two areas in Africa.
Oceanographers found the genetic ‘needles in a haystack’ to gain the first hints at how diatoms — tiny drifting algae that carry out a large part of Earth’s photosynthesis — detect and respond to increasing carbon dioxide from burning of fossil fuels.
Warming temperatures and decreasing levels of dissolved oxygen will act together to create metabolic stress for marine animals. Habitats will shift to places in the ocean where the oxygen supply can meet the animals’ increasing future needs.
The Ocean Modeling Forum is trying something very rare — bringing together multiple science models and people who care about a particular ocean resource or fishery to decide what’s most important for its vitality and the communities it serves.
Using seawater collected in Seattle, Whidbey Island and other sites, 91探花oceanographers show that just as with plants on land, a common species of ocean diatom grows faster in the presence of helpful bacteria.
Burke Museum of Natural History and Culture paleontologists have documented the first dinosaur fossil from Washington state. The fossil was collected by a Burke Museum research team along the shores of Sucia Island State Park in the San Juan Islands.
Oceanographer Deborah Kelley is one of the lead authors of a first-of-its-kind atlas of the deep sea, titled “Discovering the Deep.”
A Washington Sea Grant staff scientist is sharing top honors for developing gear that nearly eliminates seabird bycatch in long-line fisheries from the West Coast to South Africa.
A chemical signature recorded on the ear bones of Chinook salmon from Alaska’s Bristol Bay region could tell scientists and resource managers where they are born and how they spend their first year of life.
The 91探花 Board of Regents on Thursday voted to prohibit direct investment of endowment funds in publicly traded companies whose principal business is the mining of coal for use in energy generation. The Board also reaffirmed the importance of the University鈥檚 wide-ranging sustainability efforts. The vote is the culmination of a process that began in December 2012, when Divest UW, a student campaign representing more than 20 registered student organizations, sent a petition to then-President Michael K. Young…
Thaisa Way, associate professor of landscape architecture in the 91探花College of Built Environments, discusses her book, “The Landscape Architecture of Richard Haag: From Modern Space to Urban Ecological Design.”
