Albert Tsui, Business Development Specialist and patent attorney in the College of Agricultural, Human, and Natural Resource Sciences’ Office of Research, was appointed this week to the U.S. Department of Agriculture’s Plant Variety Protection Board.

Named to the 14-member board by Secretary of Agriculture Sonny Perdue, Tsui will advise the Secretary on decisions involving the Plant Variety Protection Act, which secures intellectual property rights for breeders of new varieties of plants.

“Innovation in the plant and seed industry has always been vital to agriculture, making it possible for us to meet the needs for food, clothing and other goods that American families, and the world need,” said Perdue. “With their great experience as farmers and in the plant breeding seed industry, these board members will help continue the tradition of this robust American agricultural sector.”

Members serve for two years, and represent farmers, seed industry, trade and professional associations, and public and private research institutions.

“I am proud to represent Washington State University and its academic breeding programs for this very important law protecting new plant varieties” said Tsui. “Membership on the Board helps ensure that WSU has a voice in intellectual property matters surrounding seed-propagated plants and that discoveries made at WSU and elsewhere benefit communities, growers and society to the greatest, fairest and most meaningful extent.”

April enrichment video

At the WSU Bear Research, Education, and Conservation Center, we have an enrichment program aimed at keeping our bears physically healthy and mentally stimulated. Every month, we’ll showcase the new or different activities and physical challenges our bears can tackle.

Here is a new pulley toy that Luna figures out really quickly.


Measuring bear energy goal of summer research project

This summer at the WSU Bear Research, Education, and Conservation Center, energy use is the order of the day.

From cardiac monitors to special collars to foraging experiments, WSU researchers are trying to figure how bears gather energy and then spend it.

“Bears in the wild have a very short time window to make their living,” said Tony Carnahan, a WSU Ph.D. student studying bear energy usage. “They have to make sure they have enough fat stores in their body to make it through winter. We want to figure out where and how they determine what to spend their energy on.”

To figure that out on wild bears, they’re first starting with our bears to get a baseline understanding.

The collars, worn by 9 of the 11 bears at the center, have accelerometers that measure acceleration data in three directions. The collars allow the researchers to tell when a bear is walking, running, grazing, or basically any movement the bears make. They collect 30 data samples each second, and it’s stored in a box on each collar. Every two weeks, the box is swapped out for a new one and the data is downloaded.

“It’s a lot of information to go through,” Carnahan said. “But we’ll combine it with other data and hope to figure out just how much energy the bears are using.”

Another wrinkle that’s new this year is allowing bears to primarily get energy from foraging in the exercise yard. For two weeks, two bears will have 24-hour access to the yard. One bear will be randomly selected to receive supplemental food with approximately twice the calories of a maintenance diet. The other bear will receive a supplement below a maintenance diet.

The hypothesis is that the bear on the minimal diet will spend a greater proportion of their time grazing and resting than the bear on the high calorie diet, Carnahan said.

The bears will also receive water that contains markers that can measure energy usage, a method that’s been proven for decades on a variety of animals.

In addition to the collars, nine bears at the center have an implanted cardiac monitor that feeds data to researchers regularly. So over the course of the two weeks that a bear is out in the yard, they’ll know the average heart rate for each bear and how closely heart rate correlates to energy expenditure.

Combine that with the collar data and researchers will have an excellent overview of what each bear did at any given moment, and how much energy they used altogether, Carnahan said.

The overall goal is to use the energetic values from the water to validate the cardiac monitors and accelerometers to predict energy expenditure in wild bears. Then they hope to move on and do similar work on wild bears.

Energy collection is important to learn because bears’ environments are changing rapidly. If they’re no longer able to collect energy at the same rate, or at the same time of year, that could impact their long-term survival.

“It’s all about energy collection, from the bears’ point of view,” Carnahan said. “We want to make sure they can continue doing everything they need to make it through the winters.”

Students design potential bear center

Giving students a real-world assignment makes their classwork feel more worthwhile and can let their passions come through in a way a stock assignment may not.

This past academic year, two WSU School of Design and Construction courses had students design a new WSU Bear Research, Education, and Conservation Center as class projects.

In the fall of 2017, interior design students came up with various ideas for the center’s main building. Then, this spring, landscape architecture students took some of those ideas, or created some of their own, to produce complete designs for a new Bear Center.

Each student created an infographic on the bears and their needs, another infographic focused on the inventory and analysis of the potential new site. Then they generated plan renderings for the new facility, said Landscape Architecture Assistant Professor Michael Sánchez.

“We spent a lot of time thinking about ‘What if I was a bear, what would I want?’” said Jaime Kemple, a second-year landscape architecture student in the class. “We were all really passionate about the project, and it was so intriguing and exciting that I wish we had more time to work on it.”

Many of the designs included multiple, separated outdoor enclosures, allowing more bears to spend more time in grassy open areas. The designs included water in the form of ponds or small pools for the bears to relax and cool down in.

They also included permanent, built-in enrichment structures: items for the bears to interact with that stimulate their physical and mental abilities.

The students also included more learning experiences and viewing opportunities for the public, without being intrusive on the bears’ space.

The class spoke with WSU bear experts who either work or have worked at the current Bear Center.

The major consideration for each project was the well-being of the bears.

The hope is the students can take their renderings and use them in their portfolios when applying for internships or future jobs.

“Part of our mission is to combine community learning projects into our studio work,” Sánchez said. “We like to incorporate real-world solutions that will benefit the community. This project fit that that mission.”

These projects were designed for a space in the WSU Arboretum. The students’ designs included between 20 and 40 acres of space to lay out.

“It’s a huge step up for our students, whose previous projects were on the level of a small city block or smaller,” Sánchez said. “I was impressed by how well they met the challenge and learned how to incorporate real-world issues like the current landscape and the people involved.”

In addition to speaking with bear experts, students also took a trip to a large-animal sanctuary in Spokane to see how they designed their facilities to care for their animals.

“It was good for them to see that first-hand,” Sánchez said. “They needed to see an example for how to work with the space and environment that is available and to do the absolute best you can within those constraints.”

The landscape architecture students also became emotionally invested in their work.

“We were so impressed by how passionate and dedicated the people who work with the bears are,” Kemple said. “It’s inspiring to see people who care so much about what they’re doing that you want to do your best to help them do their jobs. And to help the bears have the best possible facilities as well.”

Into the wild to study grizzlies

There’s camping, then there’s Alaska back-country, grizzly bear scientific research camping.

Joy Erlenbach and her research partner spend up to a month completely isolated in the Alaskan wilderness. Here, they set up their campsite with electric fencing to ward off bears.

That’s how WSU Ph.D. student Joy Erlenbach has spent the past three summers, and where she is right now.

“We get dropped off in the middle of Katmai National Park by a float plane, then we’re on our own for a month,” Erlenbach said before she left this year.

No showers, only one other person to talk to, and surrounded by beautiful mountains, rivers, wildlife, and waterfront. Oh, and bears. Plenty of bears.

“We’ve got two tents, surrounded by an electric fence, with maybe 20-30 bears in the meadow right outside the tent,” she said. “You can’t let your guard down. I mean, bears aren’t there to get you, but you have to always be aware of your surroundings.”

After a month, they get picked up, go shower, re-supply themselves, then head back out.

This year, Erlenbach left in April and will return to Pullman in October. She’s working on a research project with rangers at the national park to see how climate change is affecting bear behavior.

Her job is to take samples, count bears in various habitats, and see if particular kinds of bears are attracted to certain habitats.

“We want to know if females with cubs are using one kind of habitat that maybe adult males don’t use,” Erlenbach said. “We’ve noticed females with cubs often feed in the intertidal areas, land that’s under water at high tide. I can’t remember seeing a male bear out there digging for clams. It’s probably not worth it, nutritionally, for them.”

Joy Erlenbach kneels down next to a anesthetized grizzly bear in an open field with mountains in the background.

Erlenbach cherishes her time spent out in the Alaskan wilderness, becoming familiar with the bears and waking up every morning to stunning scenery. It’s not without its difficulties, however.

“I miss sleeping on a bed and having clothes that can dry out after a storm, but it’s just so beautiful and such an amazing experience,” she said.

Erlenbach got involved in this project as part of her Ph.D. program at WSU. She also earned her bachelor’s and master’s degrees at WSU.

“I started as a volunteer at the WSU Bear Center,” Erlenbach said. “I used to jog down to the center from my sorority to clean out the pens.”

After graduating, Erlenbach, a native of Burlington, Wash., moved to California for a few years. But she returned to start graduate school and hasn’t stopped wanting to work with grizzlies.

“It’s a little scary, but once you know how to read their behavior, it gets much easier,” Erlenbach said. “I can tell when a bear is agitated and doesn’t want me around. And you have to respect that. But for the most part, I’m living out a dream and enjoying these amazing experiences.”
