When a search for a tenure-track of this year several Eugene Natural History Society position opened she applied and got the job, hired as an Associate Professor in 1990. She formally retired in folk spent a weekend at the Oregon Institute of 2006 but as Professor Emerita continues to do research Marine Biology. On Saturday of that weekend there and teach part-time at the Institute. In her research she was a particularly low tide, and our November became fascinated with the ways crustaceans get speaker, Dr. Nora Terwilliger, led us on an oxygen into their systems and how it is moved about. So exploration of the intertidal zone at Cape Arago. Her she has studied the proteins that bind and transport enthusiasm was infectious at our initial rendezvous at oxygen, specifically the hemocyanin family. She looked the dining hall.

In June of 2015 our field rapid changes in environmental conditions these animals trip was again to OIMB, we again had a very low tide must deal with every few hours, as the tides rise and fall. Her research has taken her to marine laboratories on the Saturday of our weekend, and we again had and universities around the world and provided the benefit of Terwilliger’s encyclopedic knowledge opportunities to dip her toes into many bodies of water, and infectious enthusiasm as we spent hours in the including the Atlantic, Pacific and Indian Oceans, the intertidal zone at Cape Arago. And once again Baltic, Adriatic and China Seas, and the Rhine, Terwilliger is our November speaker. Okavanga, and Mara Rivers. Certain things in a person’s biography do not change over the course of six years, so here are some Terwilliger says she may have been retired when salient facts about our speaker lifted shamelessly she spoke to ENHS in 2009 but she is more retired from that introduction in 2009. now than she was then. She still teaches the Dr. Terwilliger was born in Connecticut and raised in occasional class, so she dips in and out of OIMB. a small town on Long Island Sound. As a child she and One of her recent interests is nature printing, which is her friends roamed the marshes, catching crabs, digging derived from Japanese fish printing. The Nature Print clams, fishing... does this sound idyllic or what? As a Society has annual workshops, and they had one at youngster she even had access to a boat – a wooden dory that she rowed around on the backwaters. So Nora OIMB, which Terwilliger attended. She since has was becoming a marine biologist even before she knew gone to two more of their workshops, one in North what it was. She went to the University of Vermont for Carolina and the more recent one in Port Townsend, her undergraduate work, switching back and forth Washington.

The print says nothing about From there she went to the University of Wisconsin, in the function of that object, and Terwilliger is working the Medical School Anatomy Department, for her on ways to incorporate functional as well as Master’s. She was doing electron microscopy, looking structural information into her prints. at subcellular organelles, but she missed the ocean. Nora Terwilliger loves to travel and being retired gives saw a poster for a physiology course at the Marine Biological Laboratory, Woods Hole, on Cape Cod. She her ample opportunity. This summer she hiked in the applied, and got a fellowship from the University of Italian Dolomites and snorkeled in the Adriatic Sea Wisconsin to attend. She worked on microtubules, using by Korčula, a Croatian island. She also took a road marine organisms such as sea urchins. And it was there trip around the Olympic Peninsula – her first time she met Bob Terwilliger. She finished her MS at there even though she has lived in the area for Wisconsin, and she and Bob were married. They lived decades. We can be thankful for her travel lust since in Boston for three years, then Bob got a post-doctoral her talk this year derives from her two trips to the position in the Friday Harbor Laboratory, the University Galapagos. The first, in 2013, was with a group of of Washington’s Marine Biology Institute. They fell in about 20 students from the College of New Jersey. love with the west coast. Bob was hired as Assistant By design there are two different routes through the Director of OIMB in 1970. They moved to Charleston in January of that year, in the middle of the rainiest archipelago, so tourist groups don’t get so tangled up winter Nora can remember. Nora’s research on oxygen with each other or damage these unique and stunning transport proteins in crustaceans began in 1976 while islands. That first trip was along the northern route. she and Bob were on sabbatical at Duke University’s The second, in March of this year, was more of a Marine Laboratory. This stint at full-time lab work tourist trip – about 45 persons, of mixed ages and rekindled her desire to finish her PhD, which she got in backgrounds. It followed the southern route. 1981 from the University of Oregon, working under Bill Terwilliger found the differences between the two Sistrom. She continued to do research at OIMB as well trips fascinating. The ocean currents are different, the as occasionally teaching a class. Tragedy struck in 1989, geology is different, and these differences lead to when her husband died of a heart attack. The Biology different behaviors among otherwise similar animals. The books describe chickarees and Townsend’s She now better understands why Darwin was so chipmunks as shy, more frequently heard than seen, impressed. and indeed they are very vocal, but shy and secretive When she talks to us Terwilliger will share some of they are not. How shy is a chickaree? Not too shy to her personal impressions about how this diversity sit on a blanket on the porch with our black cat manifests itself. She mentioned the Boobie as the Pascal. The blanket is for the cats, but both the chickarees and the chipmunks rip out considerable bits of it every year for nesting material. It’s polyester. No accounting for taste. About five years ago, we had a veritable plague of chickarees. They ran around inside the garden nibbling on all the sweet or starchy vegetables. They bounded about, thumping loudly on our flat roof. Every flowerpot and boot on the deck was repeatedly filled with sunflower seeds gleaned from the ground below the feeders. The crowning blow came the day I went to the big trash can where we store sunflower seeds. As I approached the barrel, the lid lifted and a Nasca Boobies chickaree stared out at me; “My place. Go away!” I chased the varmint out, put a heavy stone on the lid, classic example. There are three species of Boobies and got out the live traps. I reduced the population by in the Galapagos: the Red-footed (Sula sula), the 5 or 6 little squirrels. Relocation is a very bad thing Blue-footed (Sula nebouxii) and the Nazca (Sula to do, but I was desperate. The little guys went to granti). They have different food preferences, nice homes with feeders in town. different nesting behavior, and their flight patterns Another year, another ploy. In 2014 the Douglas differ in the routes and distances they cover as well squirrels discovered that they could shinny up the as the way they fly.

At first it was amusing to watch the Willamette Hall on the U of O campus to hear Dr. frequently failed crossings from pole to feeder, but Nora Terwilliger’s presentation “Curious Galapagos: the squirrels soon mastered the technique, and Who Lives Where, and Why.” Those of you who greedily robbed and even damaged the feeders. Just know her, or have heard her speak, know what a treat before Thanksgiving, I bought Slinkys, installed them we have in store.
