Andrews Forest Monthly Meeting June 4

Event Date: 
Friday, June 4, 2021
Event Brief Description: 

Andrews Forest Monthly Meeting: Friday, June 4, 9-11 AM

For our June 2021 meeting, we will start digging into the theme of interactions, which is the central theme of LTER8. We are going to transition from our discussions of fire over the past four monthly meetings to interactions and microclimates. 
 
Responses of species to environmental change may be mediated by both species interactions and microclimate. Our discussions of fire provides a great lead-in to microclimate as the 2020 fires left patches of differing effects both inside and outside of the H.J. Andrews Experimental Forest in the Cascade Mountain Range. Microclimate conditions create fine-scale heterogeneity across the landscape in forest canopy structure, fine-scale topography, and local habitat conditions, which, in turn, influence species, ecosystems, and their underlying processes. With these talks and conversations, we hope to kick off discussions among the research community around interactions, microclimates, and refugia.   
 
JUNE PRESENTATIONS:
 
Talk 1: Ivan Arismendi: Geophysical templates modulate the structure of stream food webs dominated by omnivory
 
Talk 2: Sarah Frey/Matt Betts: Heterospecific interactions mediate colonization dynamics of birds across a microclimate gradient
 

SCIENCE CAFÉ ABOUT INTERACTIONS
 
After our presentations, we will move into a SCIENCE CAFÉ (with virtual coffee) to discuss the topic of interactions. Everyone is welcome to participate. During this science café, we will host smaller breakout discussions around the theme of interactions at the Andrews Forest to more deeply understand the role of species interactions and microclimates. 
 
Introduction to “Interactions” in LTER8: Matt Betts
 
Breakout room discussions will focus on four topics laid out in LTER8, but we will have multiple rooms around each theme to facilitate conversation:
 
1)    How forests modulate the expression of regional climate to create local microclimate patterns in mountains (Moderator: Mark Schulze)
2)    How microclimate and legacies of land use and disturbance influence populations, communities and ecosystem processes (Moderator: Dave Bell)
3)    How species interactions amplify or reduce responses to microclimate (Moderator: Matt Betts)
4)    How values filter the use of science in land use decisions (Moderators: Michael Nelson, Chelsea Batavia)
 
We will then reconvene to briefly describe discussions in the breakout rooms.

Our meetings follow the academic year. Next meeting: October 1, 2021.  9-11 AM.

Student Spotlight Hankyu Kim

News Brief Description: 

Hankyu Kim studies birds, microclimate, and forest vegetation as a part of ongoing long-term ecological research on songbird populations at the Andrews Forest. Using long-term data, Hankyu is testing if forest microclimate can predict breeding bird population dynamics, and how the interaction of forest composition and structure regulate bird population trends. Hankyu also is studying the migration ecology of Hermit Warblers, a bird that needs mature coniferous forests for breeding. To track the birds’ movements, Hankyu put data loggers on the backs of Hermit Warblers captured on their breeding grounds at the Andrews Forest and across Pacific Northwest. Preliminary data suggests that the birds from the Andrews Forest migrate to areas of Mexico around the Yucatan Peninsula. Finally, Hankyu has studied terrestrial breeding bird population change in South Korea, linking their population dynamics with large-scale land-use change and climate change in the past two decades. Hankyu is a PhD student in OSU’s Department of Forest Ecosystems and Society, working with Matt Betts and Brenda McComb.

One of the Hermit Warblers banded at the Andrews Forest moved through a round-trip route of 6,475 miles, or 10,422 km (5,446 km in fall, 4,976 km in spring). The fall migration took approximately 3 months. Spring migration took approximately 50 days. The birds race toward breeding grounds in spring, moving about 100km per day on average, but during fall, the migration route is longer and slower as the birds need to molt their feathers on the early part of their migration.
