My @baldwinwallace.bsky.social Ecology students helped plant hundreds of trees today with Cleveland Museum of Natural History. We were happy to be part of the amazing restoration of Mentor Marsh. Everyone enjoyed dibbling!

It has been a privilege to mentor Skyanne as she grows into a scientist!
Few undergraduates earn the distinction of first author in a major scientific journal.

Read how BW student Skyanne Melton '25 achieved this milestone in Plant Ecology through research with Cleveland Metroparks on forest recovery and conservation! 👏

The research project was a collaboration with Cleveland Metroparks, fellow students and a key faculty mentor.

Yep that's my grad school buddy who has explained everything with his new book!
Please join the Teacher Institute for Evolutionary Science in welcoming Mark Vellend to a virtual event to discuss his new book, Everything Evolves, tomorrow (September 24th) at 7:00 pm EDT.

I really hate being captain science buzzkill.

"That science-y thing you're all talking about and excited about? Actually it's not true. But please still care about science!"

Ugh. It's no fun.

But it's not true! And it matters that it's not true! Someone should say so!

A friend gave me some buckeyes, the lovely peanut butter and chocolate candy. Ohio buckeye is the most toxic tree in our flora, with potentially lethal doses in all plant parts. There is some irony that the candy is delicious but the actual nut can kill you, and that the Ohio state tree is toxic.

Ecologists seek to understand how species distributions relate to environmental factors, but often these relationships have been radically human-altered. This new paper by Flinn et al. uses historical data & SDMs to understand the presettlement distributions of forest trees. doi.org/10.1111/jvs....
Presettlement Tree Distributions and Forest Types of Northeast Ohio, USA, Mapped With Species Distribution Models
Using species distribution models to map the presettlement vegetation of northeast Ohio, we found that tree distributions depended largely on elevation and slope. Fagus grandifolia had the largest ar...

Imagine our profession was built so that you could advance your career without moving all the time. Isn't this a huge piece of the equity and access problem? Yes, it is.
Needing to move is a huge barrier to broadening representation in the sciences
Science will be more inclusive and equitable when we stop expecting people to uproot their lives every few years

Our new analysis of land use change in Cuyahoga County, home of Cleveland, Ohio, published today in Urban Ecosystems. We trace how urbanization has impacted our native forests over the past 220 years, providing context for current growth. Highlights in thread: 🌿🧪🌎

There's a deep sense of sadness and loneliness seeing this record shattering graph.

November 17, 2023 was the first day in recorded history when the earth's surface was a whole 2°C hotter than pre-industrial times. Yet, there's barely any chatter about this staggering breach.

Spotted my first lanternfly, at Cleveland Metroparks' Lakefront Nature Preserve, which is a peninsula in Lake Erie. This invasive crop pest recently arrived in northeast Ohio and lives primarily on tree of heaven. How did she get here? 🌿🌎

How lucky that my birthday coincides with the persimmon harvest! I'm making persimmon pudding with fruit I gathered from this native tree. Find a persimmon tree if you can... yes, they're seedy and squishy, but the flavor is worth it and like nothing else. 🌿

New here, so an introduction: I'm excited to be here and connect with fellow scientists & naturalists! 🌿🌎🧪
I am a plant ecologist using historical ecology to understand how ecological communities have changed over the past ~300 years or so in my home landscape of northeast Ohio, around Cleveland.

I experienced the katsura smell for the first time! The yellowing leaves smell fruity, malty, caramelly... like cotton candy, apple cake or a fruity beer. As they decay, they release maltol. Beautiful, old weeping specimen @ Secrest Arboretum. 🌿

@friel.bsky.social Hi John! Could you add me to the naturalists feed? Thanks!

Katsura tree leaves in fall smell like caramelized sugar. Who has experienced this and how would you describe it?
