The second session is all about assessing and detecting stress effects. We are about halfway through with a great talk by @yuwenzhang6666.bsky.social #DendroNet

First keynote from Kathy Steppe at Universiteit Gent disentangling tree growth components 🙌 Understanding sap flow and tree growth is critical in the context of climate change #DendroNet

Passed my phd defense last week 🥳🕺😎
Big thanks to my committee for the thoughtful discussion, making the 3 hours fly by.
L-R: Steve Lougheed, Paul Treitz, me 👋, Ross Hill, Erica Nol, and Ryan Danby.

5/🧵 we then examined the changes through time using metrics of unfilling, stability, expansion and overlap.
This confirmed that there was expansion, but that the core niche area was stable, as the Chiffchaff population has grown.

4/🧵 using PCA to represent niche, we could easily visualize that Chiffchaff niche grew through time.
And that our lidar metrics, particularly mean height, foliage height diversity and canopy closure, were particularly important to PC1 which captured 77% of the variance in the data.

3/🧵 we extracted lidar metrics describing horizontal (like canopy closure) and vertical (like mean height) woodland #habitat components at four time steps at Chiffchaff locations.

2/🧵 Species distribution models generally assume that the relationship between a species and their habitat is stationary, but there are a lot of reasons this might not be true.
Like population growth.
Thanks to @btobirds.bsky.social, we know that Chiffchaff population has grown a lot.

1/🧵 Today at #BOU2025, I'm sharing my work using a #lidar time series to examine temporal Chiffchaff niche dynamic.
tl;dr as the population has grown, Chiffchaff niche has expanded.

A dreamy day for a stroll in the countryside revisiting my woodland study sites. Particularly enjoyed noticing all the borders and thought about birds noticing the same.

I like what Elton had to say ~100 years ago. Elsewhere, he noted something along the lines of ecology being fun work, but made for a boring read 😂

Cracked a classic courtesy of the library. I see it cited all the time in niche related research, along with Grinnell & Hutchinson, but just getting to it now.
