Excited to share our latest preprint! 🌱📸🤖

Very interesting and accessible take on probability worth a read!

Last week, I attended the British Ecological Society meeting for the first time and enjoyed a range of fascinating talks. I also had the opportunity to present our project on the predicted impacts of climate change on the germination of UK tree populations. #kewscience @britishecolsoc.bsky.social

A rude awakening: the risks of climate change for sleeping seeds What happens when seed dormancy meets climate change – and why it matters for our forests.

Check out our recent blog post on tree seed germination under climate change, where we share insights from our current research. #SeedScience #ClimateChange 😴❄️🌱

It took months to grow seedlings from seeds of some species featured in these photos. Take the quiz by @pagomba.bsky.social and see if you can identify them!

OBS: The feature is helpful for analyses where tracking individual seeds or objects is essential. Otherwise, the original version is still recommended! I have not widely tested this update, so please keep an eye on the results and let me know how it works for you.

With this new method, we hope to open new avenues for exploring the functional relevance of morphological traits and advancing new tools for seed identification. #SeedMorphology #TraitExtraction #ImageAnalysis #Automation #SeedEcology #OpenScience #highthroughputphenotyping (7/7)

We also show how the output can be used to build objective classification categories for shape with high visual interpretability. (6/7)

In the paper, we demonstrate how Traitor's output can be used to obtain representative seed colours for taxa and determine the phylogenetic signal of seed colour. (5/7)

You don't need to know Python to use Traitor! Once you've installed the required software, you just need to enter some basic commands in your computer's prompt or terminal to extract the traits. Check out our instructions here: github.com/TankredO/trait… this is the original version! (4/7)

Traitor effortlessly separates seeds from high-contrast backgrounds. There is no need for training, manual fine-tuning, or thresholding. You can extract traits from hundreds of images from various taxa with just three simple commands! (3/7)

Our approach combines a simple image acquisition protocol with Traitor, an open-source software that 'exposes' seeds, revealing their size, shape and colour measurements. (2/7)

We introduced a method to automatically extract objective and interpretable seed morphological traits from images. doi.org/10.1111/2041-2… (1/7)

🌱 Hello to everyone interested in extracting seed measurements from images! 🌱

I’ve released an experimental version of Traitor, featuring a new option requested by some users: ordered output to keep track of individual seeds during analysis.

Never heard of Traitor?👇🧵

Sapwood phosphorus concentrations for temperate, subtropical and tropical trees

🧪 Happy to share a link to our Tansley Review on wood nutrients: underexplored functional traits. nph.onlinelibrary.wiley.com/doi/epdf/10.... We highlight the enormous variation in wood nutrient concentrations among species, links to masting, resprouting and ecosystem carbon via decomposition.

Check out the thread below for highlights from our latest paper! 👇 #SeedEcology

Today, I presented our latest work on using image analysis to enhance the use of native seeds at the Congresso Brasileiro de Sementes. Thrilled to see image analysis solutions and the need for collaborative databases getting more attention at seed meetings!
