Centennial Stories 2

William G. Clark (PhD, 1975)
In 1969, I had a degree in economics and mathematics from the University of Michigan, but what I really wanted to do was to go to graduate school and build computer models of marine ecosystems. I interviewed at a number of oceanography departments, and they all turned me down because I didn’t have any undergraduate credits in biology.

Centennial Stories 1

Dick Myhre (School of Fisheries, BS 1950)
I graduated from high school in 1939 and enlisted in the Washington National Guard in November of that year.  The National Guard was activated in September 1940 and that meant I was on active duty in the Army.  I received my Honorable Discharge in October 1945 and was able to attend the UW on the GI Bill.

Why do some species associate together? Habitat is the key, not randomness

The species found in a particular place (“species assemblages”) differ from those found in other places, and figuring out why this is so has occupied the minds of ecologists since the mid-20th century. Currently two theories dominate: the niche theory, and the neutral theory. The niche theory holds that species assemblages result from species migrating into a particular place, and then either thriving or leaving based on how good of a match they are to the habitat and other living organisms (the “niche”) in that place.

To reduce human infections, control the snails

Schistosomiasis (also known as billharzia) is a parasitic flatworm that infects a quarter of a billion people worldwide, mostly in tropical countries. If left untreated, it causes chronic pain and diseases of the liver and kidney, and kills up to 200,000 people annually. In recent years, control of the disease has focused on mass-treating humans with a drug called praziquantel, instead of reducing the prevalence of snails that are a required part of the parasite’s life cycle.

Fewer big and old Chinook salmon in the Pacific

Chinook salmon (king salmon) are the most prized salmon in the Pacific because of their large size. But now an analysis shows that the oldest Chinook salmon are disappearing, and their size is also declining, and these patterns are seen from California to western Alaska and in both wild and hatchery Chinook salmon. The research by SAFS researchers Jan Ohlberger and Daniel Schindler, and their coauthors Eric Ward and Bert Lewis, appears in the journal Fish and Fisheries, and was highlighted in UW News.

An overlooked carbon source to an important freshwater fishery may be under threat

By Ben Miller, SAFS student
When you first arrive at the community of Kampong Phluk, your neck cranes up bamboo stilts to meet the chatter of families in houses high above. From the top of what guidebooks call “bamboo skyscrapers,” locals gaze over the tops of submerged trees, a glittering, island Buddhist temple, and clusters of floating fishing villages in the distance.

Undergraduate blog highlights scientific stories at the heart of the Bevan Series on sustainable fisheries

The Bevan Series is the premier seminar series at SAFS, bringing 10 speakers each year from around the globe to discuss, debate, and challenge our community to listen to different perspectives. This year, the associated undergraduate class has been writing a series of blogs, one for each speaker. In the most recent post, undergraduates Carter Johnson, Ethan Seay, and Max Urbanek highlight for Valentine’s Day the relationship tips needed for science and policy.

SAFS professor Chelsea Wood receives prestigious Sloan Fellowship

SAFS Professor Chelsea Wood was awarded a Sloan Fellowship, awarded to early-career researchers in recognition of distinguished performance and a unique potential to make substantial contributions to their field. Prof. Wood is a prolific researcher who uses parasites and pathogens (both human and fish-based) to uncover fundamental ecological truths about the natural world. She will receive $65,000 to further her research initiatives, which includes using museum fish specimens as “parasite time capsules”, as reported in UW News.

Baby salmon use the earth’s magnetic field to figure out which way is up

Salmon are capable of using the Earth’s magnetic field as a part of their built-in navigating skills to home back to their streams of birth. Now it has been discovered that young salmon emerging from the gravel also use the Earth’s magnetic field to figure out which way is up. Salmon eggs are laid in gravel nests, and the young salmon remain in the gravel until all of the attached yolk reserves are finished, then they emerge to live out in the open water.

With sea ice loss, beluga whales make longer and deeper feeding dives in the same places

Satellite tracking devices on beluga whales in the Arctic show how they reacted to far lower sea ice concentrations in recent years. Instead of shifting where they feed, as might have been expected, beluga whales continued to feed in similar (but now largely ice-free) places. However, where dive data were available, their dives were significantly longer and deeper than in years with higher ice concentrations.
