Climate change poses known and unknown risks for coastal communities and also challenges for university faculty and local government staff who communicate about climate sciences. Conceived as a way to move beyond traditional models of science communication, this project involved public and private decision makers in specific at-risk communities in...
The ability to determine a bulk estuarine turnover timescale that is well defined under realistic conditions is in high demand for estuarine research and management. We compare how turnover timescales vary with tidal and river forcing from idealized forcing scenarios using a three-dimensional circulation model of the Yaquina Bay estuary...
Since the decimation of the southern right
whale Eubalaena australis population in New Zealand by
whaling, research on its recovery has focused on the wintering
ground at the Auckland Islands, neglecting potentially
important wintering habitat at Campbell Island. For
the first time in 20 years we conducted an expedition to...
The Fishermen Led Injury Prevention Program is the first and only research focused on non-fatal injury prevention among commercial fishermen.
• No fishermen reported that they had zero chance of injury, regardless of injuries sustained in career and/or in the past year.
• Fishermen who have sustained an injury...
Periodic weighing of seabird chicks is labour-intensive and repeated handling can cause high levels of disturbance to chicks. Although automatic weighing systems using a fibreglass nest have been designed for albatross species with a pedestal nest made of mud, this approach is inappropriate for great albatross species (genus Diomedea) whose...
Koi herpesvirus (KHV) is highly pathogenic to Cyprinus carpio. KHV can also become latent in recovered fish and reactivate from latency under stressful conditions. Understanding KHV latency is important for development of strategies against herpesvirus latent infection. Our previous studies found KHV ORF6 mRNA is detectable during latent infection. In...
Rebuilding of some U.S. West Coast rockfish (Sebastes spp.) stocks relies heavily on mandatory fishery discard, however the long-term condition of discarded fish experiencing capture-related barotrauma is unknown. We conducted two studies designed to evaluate delayed mortality, physical condition,and behavioral competency of yelloweye rockfish, Sebastes ruberrimus, experiencing barotrauma during capture...
Streams that dry during part of the year are common throughout the world, yet studies of the macroinvertebrate assemblages in these types of streams are rare compared to those in permanent streams; and studies that assess the effects of agriculture on temporary stream invertebrates are even rarer. We studied macroinvertebrate...
Models that seek to predict environmental variables invariably demonstrate bias when compared to observations. Bias correction (BC) techniques are common in the climate and hydrological modeling communities, but have seen fewer applications to the field of wave modeling. In particular there has been no investigation as to which BC methodology...
Select an “Invader” species found in the Pacific Northwest. Research, design, publish and present a high quality informative Not Wanted Poster/Product.
Students use an online quarantine estimator to determine how long zebra mussels can survive out of water. By varying the settings, such as location in country and month of the year, students can observe how the time needed to dry a boat is related to the time of year and...
Students pretend to be “invasion investigators” and investigate the appearance of a mysterious new snail in their local creek. Student research the identity and ecology of this new mysterious snail, and design experiments to understand its impact.
How big can a nutria population get? In this activity, students calculate and graph the growth rate of a population of nutria based on a set of realistic assumptions.
In this fun activity, students guess answers to clues about invasive species on a bingo-like game-board, and serves as a great introduction for students and teachers alike.
This lesson uses the image of a jumping Asian carp to use the physics of ballistics to calculate the speed at which a jumping carp will hit the water (or you! OUCH!)
Students conduct a "blitz" by quickly rotating through hands-on specimen stations and answering the BioBlitz questions. Then, students are assigned one invader to research more thoroughly and present to the class.
(Same lesson plan as Myocaster Multiplier but a more challenging student activity.)
This more advanced version of Myocastor multiplier asks students to take into account predation when calculating population growth rate.
Students practice geographical skills to map the routes of invasive species from their native habitat to some of the regions to which the exotics have spread.
In Design the Ultimate Invader, students use their imagination to design the ultimate invasive species. This activity is a perfect way to launch a unit on invaders, and can serve as an assessment tool to help us learn the knowledge of our learners towards invasive species and invasion biology.
The nutria is a large, semi-aquatic rodent native to South America. Nutria were introduced to the United States for their fur. After a boom in nutria ranches during the 1930s, the animals escaped or were released from fur farms in the Pacific Northwest, Louisiana and other states, where theyare now...
Knotweeds are a group of closely related invasive plants from Asia. Knotweeds are very tall plants that can grow to over three meters with bamboo-like hollow stems and heart-shaped or lance-shaped leaves. They spread quickly and form tall, dense thickets. They dominate stream banks, sides of roads, gardens, and other...
The American Bullfrogs are a highly reproductive aquatic species that are native in central, eastern United States and Southeastern Canada. This species was first introduced to western America as a food source (frog legs!); since then it escaped aquaculture ponds and have spread widely. Bullfrogs lay up to 20,000 eggs...

Colonies of millions of quagga and zebra mussels foul and clog pipes, water treatment plants, and dam turbines and give a competitive boost to toxic algae. It takes only one contaminated boat and the right conditions for zebra and quagga mussels to infest a new watershed; once they have been...
Asian carps—fish in the Cyprinid family—have been part of our culture for centuries. We use them as ornamental aquarium fish (goldfish and koi) and food fish, and to help keep aquaculture ponds clean. However, when Asian carps escape into natural waterways, they can cause big problems for human health, the...
What ancient animal in modern times has a primitave spinal cord that may resemble the first vertebrates on earth, spends most of its life stuck to a boat or rock, produces an exoskeleton made of cellulose and is more associated with plants than animals? Tunicates are marine invertebrate filter feeders...
Crayfish are one of the most threatened groups of animals in the world. About 45 percent of North American crayfish species are considered to be at risk of extinction. However, a few crayfish species are among the world's most invasive freshwater organisms. Taking into consideration that invasive crayfish are the...
Hydrilla and Brazilian elodea are invasive aquatic plants that occupy freshwater habitats. While hydrilla is native to Asia, Africa, and eastern Australia, and Brazilian elodea is native to South America, both plants are invasive to North America. Because these plants are related and both have pointed green leaves that whorl...
New Zealand mudsnails are a highly invasive species of freshwater mollusk of the family Hydrobiidae, also known as spring snails. Their ability to clone themselves and maintain high reproductive rates allows them to rapidly spread throughout the western United States. Some estimates indicate that one female can clone and produce...
The Chinese mitten crab was first identified in the south San Francisco Bay in 1992 by commercial shrimp trawlers, and quickly spread to the Sacramento and San Joaquin Rivers. The Chinese mitten crab threatens ecosystems, earthen structures, and fisheries by preying on and competing with many species, including fish eggs,...
