Stream Temperature and Insect Emergence

Phenology is the study of the timing of major life-cycle events of organisms. A general prediction under climate change is that phenological events will occur earlier with increasingly warmer temperatures. For aquatic insects, a major life-cycle event is emergence, the transition of the aquatic juvenile stage to a terrestrial flying adult. We asked a simple question: If aquatic insects experience warmer water, do they emerge earlier? The answer, it turns out, is not so simple.

Forests as climate refuge for animals

In the face of a warming climate, organisms may find at least temporary refuge in cooler nooks and crannies of a landscape. Previous work from the Andrews Forest (Frey et al. 2016 – Science Advances) found that sites with concave microtopography and with old-growth forest structure tended to be cooler than other locations across the landscape. But how consistent is this effect? If plants, animals, fungi etc.

Next-generation natural history

Marie Tosa is a PhD student in the Department of Fisheries, Wildlife, and Conservation Sciences at Oregon State University working with Damon Lesmeister and Taal Levi. Marie spent 2.5 years from 2017-2019 at the Andrews Forest investigating the ecology of the western spotted skunk and surveying the biodiversity of numerous taxa including vegetation, fungus, invertebrates, birds, and mammals. Using camera traps and radio-collars, Marie captured and tracked 31 spotted skunks and has collected data on survival, movement, rest sites, and diet.

Graduate Student Christopher Cousins Receives Bullitt award

News Brief Description: 

Graduate student Christopher Cousins was awarded the Bullitt Environmental Award for his work in connecting his research on amphibians with outreach to Latino youth. Cousins, with the help of his advisor, Tiffany Garcia, and others, is writing a bilingual children's book about frogs, salamanders, and their habitat in the Pacific Northwest. Read more at The Bullitt Foundation website,  KLCC radio and the Corvallis Gazette Times.  Congratulations, Chris! 

Hankyu Kim PhD Defense Aug 30 1PM

Event Date: 
Monday, August 30, 2021
Event Brief Description: 

Please join us on Monday, August 30th at 1 pm on Zoom for a presentation of Hankyu Kim’s dissertation, titled: “An examination of climate and land-use change as drivers of population dynamics in breeding bird populations.” Hankyu is earning his PHD in Forest Ecosystems and Society with Brenda Mc Comb and Matt Betts.

Identifying population changes of birds and drivers of changes over space and time is essential for effective species conservation. Using data collected from the field and archive, Hankyu 1) modeled and analyzed bird population status, 2) tested fine-scale drivers of population changes, and 3) identified migratory movements across the annual cycle of a declining bird species. First, Hankyu quantified the occupancy change of breeding birds in South Korea in the past two decades. Next, he tested if microclimate buffering effect and compositional and structural diversity of forests can mediate negative effects of warming on bird populations at the HJ Andrews Experimental Forest in Oregon, USA. Finally, Hankyu tracked hermit warblers from six breeding populations across their range in the Pacific Northwest.
