Dams, climate change, habitat loss, predation, anglers. Wild salmon must contend with all of these challenges during some point in their lifetimes. But an additional challenge may be having a negative impact on wild salmon that we don’t yet quite understand: hatchery salmon. The main purpose behind rearing and releasing hatchery salmon into the wild is to increase the number of fish available for anglers (both recreational and commercial) to catch since wild salmon populations are too low in many areas to yield sustainable catches. However, when hatchery fish are released into the wild, some individuals stray. The term straying describes when hatchery fish go where they are not supposed to go. While some degree of straying can be positive because it helps maintain or increase genetic diversity within wild populations, too many hatchery strays could lead to problems for wild salmon. Investigating the impacts of hatchery salmon on wild salmon is no easy feat, and it’s not made easier when you’re trying to do it in possibly one of the most remote and wild places in Oregon…
But that’s exactly what our guest this week is doing! Emily Treadway is a first year Master’s student advised by Dr. Seth White in the Department of Fisheries, Wildlife, and Conservation Sciences at OSU. On top of being a graduate student, Emily is also an employee at the Oregon Department of Fish and Wildlife working within the East Region Fish Research Office. By wearing these two hats and through support from the Lower Snake River Compensation Plan, Emily’s Master’s research aims to do three things: (1) establish baselines for the Wenaha River, (2) determine how a remote region like the Wenaha can be monitored cost-effectively into the future, and (3) hopefully implement certain mitigation efforts or designs that will help support healthy wild salmon populations.

Going to college is an overwhelming and all-consuming experience. To help students cope with the new realities of college life, universities typically provide huge amounts of resources and support to freshmen during their first year. Once students hit their sophomore year, the assumption is that students are returning to something they’re already familiar with; they know what resources their school has to offer, how to sign up for classes, where to buy the best lunch on campus, and so on. Sophomores are expected to independently way find and the amount of support and provided resources fizzles out. This phenomena is referred to as the sophomore slump as research has shown that sophomores are in fact quite vulnerable compared to other college classes because of this drop-off in support. Shania Siron, who is in her third (and final!) year and advised by Dr. Tenisha Tevis at OSU, is our guest on the show this week and the focus of her Doctorate of Education dissertation research is the sophomore slump. Shania’s research aims at better understanding how college sophomores develop their abilities to self-author through engaging with career services, which Shania is pretty well-placed to do given that she doesn’t just wear a graduate student hat but she in fact also works full-time as the Assistant Director of Career and Fellowship Advising at Reed College in Portland, Oregon.

Foot-and-mouth disease (FMD) virus is one of the most infectious viral diseases in the world. FMD virus affects all cloven-hooved animals and there have been outbreaks all over the world except for in North America. While FMD virus doesn’t necessarily cause fatality in animals, it causes severe milk production losses and can leave affected individuals severely weakened and debilitated. This is particularly problematic for people who keep livestock as it can affect their livelihoods and economic welfare. Our guest this week is Cambrey Knapp, a 2nd year PhD student in Comparative Health Science who is studying wildlife-livestock interactions related to FMD virus around Kruger National Park in South Africa. African buffalo within Kruger National Park harbor FMD virus and it can spillover to livestock that are kept in the surrounding areas outside of the park. Cambrey’s research is investigating which viral lineages of FMD virus are most prone to spillover and the temporal aspects of transmission by looking at historic and contemporary African buffalo and cattle samples.

Studies have shown that birthing mothers paired with doulas have better birth outcomes than mothers that do not work with doulas. For example, doula-assisted mothers are four times less likely to have a low birth weight baby, two times less likely to experience a birth complication and are significantly more likely to initiate breast-feeding, compared to non-doula-assisted mothers1. Yet, the doula workforce suffers from high levels of burn-out often due to being underpaid, overextended, and disrespected in their work, which often results in doulas leaving the profession2. Given the clear benefits of doula-assisted pregnancy and birth, these issues need to be solved. But, how? Well, one person on the job is Master’s student Katie Minich! Katie is in the Applied Anthropology program working with Drs. Melissa Cheyney and David Lewis. Katie’s research aims to better understand how we can improve the sustainability and best practices for doulas post-training.
Tune in to our interview with Katie this Sunday (May 26th) at 7 pm PST on KBVR 88.7 FM. We will be covering a whole range of topics, including Katie’s eight years of experience as a doula herself, why Oregon is one of the best places to be a doula in the US, and more!

Do you feel dizzy after reading that title? Me too, after writing it, but this week on the show we did indeed speak to a trainer of the trainers who train trainers of little humans! Meet Maya Johnson, a 3rd year PhD student in the School of Human Development and Family Sciences. For her research, Maya studies early childhood education policy and the childcare system within Oregon, with a pretty applied policy focus. Alongside doing her research, in her capacity as a graduate research assistant at OSU, some of what Maya does is to write trainings and coaching systems for individuals who train early childhood educators (hence the trainer of trainers who train trainers).
Check out our interview with Maya wherever you get your podcasts, including on our KBVR page, Spotify or Apple Podcasts! We cover a whole range of topics related to early childhood education, such as the HeadStart program, the childcare crises, why we don’t know a whole lot about the education stats of children under the age of 6 in Oregon, and what Maya is doing to hopefully change that problem!

On our last episode for winter term, we interviewed Kayla Fratt, who is currently a PhD student in the Department of Fisheries, Wildlife, and Conservation Sciences. However, aside from being a graduate student, Kayla is also one of the founders and trainers for K9 Conservationists, an organization that unites highly trained conservation detection dog teams with researchers to collect scientific data. For her graduate research, Kayla is working with her canine colleagues, Barley & Niffler, to understand island biogeography effects on diet and movement for sea wolves in southeast Alaska and basic natural history of pumas in El Salvador.

Due to some unforeseen circumstances, we had a very impromptu guest join us for our show on February 18th. Rachel Kaplan is a 4th year PhD student in the College of Earth, Ocean, and Atmospheric Sciences, who researchers whales and krill around the world to better understand predator-prey dynamics. Part of her PhD research involves going to Antarctica so we sat down with Rachel to chat about what it’s like conducting field work on the coldest continent on Earth!

This week on ID we interview El Rose, a talented first year MFA student of non-fiction in the School of Writing, Literature and Film. El draws on their background growing up in rural Arkansas to write about topics of class, immigration, intergenerational trauma, identity, and the intersection of it all.
Their work falls primarily within the realm of memoir. ‘Memoir’ is derived from the French word ‘mémoire’, which means ‘reminiscence’ or ‘memory’. Memoir falls into the category of non-fiction but is ultimately a subjective narrative in which the author remembers experiences, emotions, and events from a certain event or period in their life. Memoirs focus on conveying their perception of these memories in a way that is emotionally truthful but isn’t necessarily factual.
El began their journey in writing at the University of Memphis, although they’ve been writing in one manner or another for most of their life. They spent eight years between finishing undergrad and coming to OSU, working through the ranks in the food industry and eventually becoming an owner of a cafe in the Portland area. Through a series of perfectly timed events, and their own desire to make more space to take their writing seriously, El came to OSU to set out on the grad school journey.
To hear more about how writing a memoir works, as well as El’s journey from Arkansas to Oregon, tune in this Sunday, November 12th live on 88.7 FM or on the live stream. Missed the show? You can listen to the recorded episode on your preferred podcast platform!
Getting to the bottom of what top predators in an ecosystem are eating is critical to understand how they may be influencing dynamics in the entire system and food web. But how do you figure out what a predator is eating if it’s hard to catch and collar or watch continuously? Easy, you use their poop! Ellen Dymit, a 4th year graduate student in the Department of Fisheries, Wildlife, and Conservation Sciences advised by Dr. Taal Levi, is our guest on the show this week and she is a poop-tracker extraordinaire!
For her PhD research, Ellen uses primarily non-invasive genetic methods to study large carnivores in two projects in Alaska and Central America. While the systems and carnivores she studies for these two projects are pretty different, the techniques she uses to analyze the collected scats are the same. The Alaska project is focused on determining what different wolf populations and packs across coastal Alaska are consuming, whether individuals are specialized in their feeding habits, and how large the populations are. The Central America project, which is based out of Guatemala, looks at a whole host of predators, including jaguars, pumas, and ocelots, to gain a better understand of the food web dynamics in the ecosystem.
One of Ellen’s extremely remote field camps in Alaska
Both of these projects involve some unique challenges in the field that Ellen has had to learn to tackle. DNA can deteriorate pretty quickly, especially in warm Guatemalan temperatures, which is problematic when you’re trying to analyze it. Yet, Ellen’s lab has perfected methods over the last few years to work with neotropical samples. Ellen’s Alaska field work is incredibly remote as it’s just Ellen and one field technician roaming the Alaskan tundra in search of wolf scat. Accessing her field sites involves being flown in on a small fixed wing plane, where they are extremely space and weight-limited. Therefore, every single piece of gear needs to be weighed to ensure that the pilot has enough fuel to get to the site and back. As a result, Ellen isn’t able to collect the entire scat samples that she finds but can only take a small, representative sample.
Ellen sub-sampling a wolf scat
Ellen’s incredibly adventurous field work is followed by months spent in the lab processing her precious scat samples. So far, her results have revealed some pretty interesting differences in diet of wolf packs and populations across three field sites in Alaska. The Guatemalan project, which occurs in collaboration with the Wildlife Conservation Society Guatemala, is one of the first to analyze a large sample size of ocelot scats and the first to attempt DNA metabarcoding of samples collected in the neotropics.
To hear more details about both of these projects, as well as Ellen’s background and some bad-a$$ stories from her Alaskan field work, tune in this Sunday, October 15th live on 88.7 FM or on the live stream. Missed the show? You can listen to the recorded episode on your preferred podcast platform!
Lots of terrestrial invertebrates have bad reputations. Spiders, bees, flies, wasps, ants. They’re thought of as pests in the garden or they are perceived as threatening, possibly wanting to sting or bite us. I’ll admit it, I’m terrified and grossed out by most invertebrates every time I see one in my house. But this week’s guest may have successfully managed to get me to change my tune…
Scott (left) and his intern/doppelganger Tucker (right) in the field.
Scott Mitchell is a 4th year PhD student in the Department of Fisheries, Wildlife, and Conservation Sciences advised by Dr. Sandy DeBano. His overarching research goal is to understand how different land management practices may impact beneficial invertebrate communities in a variety of managed landscapes. Yes, you read that right: beneficial invertebrates. Because while many invertebrates have a bad rep, they’re actually unsung heroes of the world. They pollinate plants, aerate soil, eat actual pest invertebrates and are prey for many other species. In order to tackle his overarching research goal, Scott is conducting two studies in Oregon; one focuses on native bees while the second looks at non-pollinators such as wasps, spiders, and beetles.
(See captions for images at the end of the blog post)
The first study occurs in the Starkey Experimental Forest and Range which is managed by the US Forest Service. The initial research at Starkey in the 1900s was about how cattle grazing impacts on the land. Since then, many more studies have been undertaken and are ongoing, including about forest management, wildlife, plants, and recreation. For Scott’s study, he is collaborating with the Forest Service to look how bee community composition may differ in a number of experimental treatments that are already ongoing at Starkey. The two treatments that Scott is looking into are thinning (thinned vs unthinned forest) and ungulate density (high vs low). The current hypothesis is that in high ungulate densities, flower booms may be reduced due to high grazing and trampling by many ungulate (specifically elk) individuals, thus reducing the number of available blooms to bees. While in the thinning treatments, Scott is expecting to see more flower blooms available to bees in the thinned sites due to increased access to light and resources because of a reduced tree canopy cover. To accomplish this project, Scott collects bee samples in traps and handnets, as well as data on blooming plants.

Scott’s second study explores non-pollinator community composition in cherry orchards in the Dalles along the Columbia River Gorge. Agricultural landscapes, such as orchards, are heavily managed to produce and maximize a particular agricultural product. However, growers have options about how they choose to manage their land. So, Scott is working closely with a grower to see how different plants planted underneath orchards can benefit the grower and/or the ecology of the system as a whole.

Image 1: This bright green native bee is foraging on flowers for nectar and pollen. It is probably in the genus Osmia.
Image 2: A brightly colored bumblebee foraging on a rose.
Image 3: This is one of the most common bumblebee species in western Oregon – the aptly named yellow-faced bumble bee (Bombus vosnesenskii).
Image 4: Most native bees, like this small mining bee are friendly creatures and will even crawl onto your hands or fingers if you let them. No bees (or human fingers) were harmed in the making of this photo.
Image 5: While Scott doesn’t know what his favorite wasp is, this large furry, friendly bee is his favorite native bee species. It is known as the Pacific digger bee or Anthophora pacifica. This is his favorite bee because they are very agile fliers and fun to watch foraging on flowers. They are a solitary species that lives in the ground.
Image 6: Not only are wasps beautiful, but sometimes the signs they leave behind can be too. This is a gall from a gall forming cynipid wasp. Wasp galls are a growth on plants that occurs when a wasp lays its eggs inside of a leaf or other plant structure.
Image 7: This is a pair of wasps in the family Sphecidae. The wasp on top is a male wasp (males are often smaller than females in wasps and bees) and he is likely guarding a potential mate by hanging onto her back.
Image 8: This is a beautiful bright metallic jewel wasp, probably in the family Chrysididae. This wasp was mentioned in the episode.
Image 9: This sphecid wasp is foraging on nectar on flowers. Many insects, including wasps, use nectar as an energy source in their adult life stage – even if they act as predators when foraging for their young.
Image 10: This is a tiny wasp on a flower. This wasp is around 1.5-3 millimeters long.
