🇵🇷 Boricua archaeobotanist, dedicated to the study of microbotanical remains (phytoliths and starch grains)🌾🔬. My research focuses on foodways, plant use, and socio-ecological interactions in prehistoric Southwest Asia and the Neotropics.

Why do some plants grow tiny glass-like structures called phytoliths? New research by @jehovalourenco.bsky.social reveals that monocots evolved this trick twice - and some later dropped it.
A story of convergent evolution, loss, an cellular creativity

Silica mapping (in red) in leaf transverse sections of Asparagales. (A–E) Orchidaceae–Epidendroideae, silica deposits mostly restricted to bundle sheath cells (with fragments elsewhere), absent from epidermis. (A–D) Dendrobium ×delicatum (Epidendroideae–Orchidaceae), (A) entire vascular bundle with phytoliths in bundle sheath cells, (B) single phytolith inside bundle sheath cell, (C: silica 0.8%) leaf section, and (D) group of phytoliths on bundle sheath surface. (E) Bletilla striata (Epidendroideae–Orchidaceae), phytoliths mostly restricted to bundle sheath cells. (F) Astelia fragrans (Asteliaceae–Asparagales), showing part of epidermis and vascular bundle; no silica detected throughout leaf. Map sum spectra of elements shown in C and F (inset). Scale bars: A, C = 100 µm; B = 5 µm; D = 10 µm, E = 50 µm; F = 100 µm.

We took a break to visit El Yunque National Rainforest. It's also impressive how the forest has recovered from the devastating Hurricane Maria.

We're back in Puerto Rico to continue our archaeological work at Caguana! Over the past months, we've processed some of the sediment samples with great results. Now it’s time to dive into lab work and take a closer look at materials from one of the most promising excavation units.🌿🏺🔬
