This morning at #ESA2026 in Salt Lake City, we acknowledged the 2026 ESA Excellent in Ecology (EEE) Scholars! Meet the four members of this year's cohort 🧵
This isn't just a paper about insects. It's a demonstration of what decades of biodiversity inventory, conservation, and scientific collaboration can achieve. Congratulations to Dan & Winnie, the parataxonomists, and all the authors on this remarkable PNAS publication. www.pnas.org/doi/10.1073/...
So excited to announce our search for 4 postdocs (funded by the Simons Foundation) who will use genomics to "test how ecological interactions, natural selection, natural enemies, hybridization & environmental gradients shape...tropical tree communities" in Panama: stri.si.edu/story/bci-ev... ...1

Busy week for the SuperInvaders project! 🌱 Jenna & Alana leading the way on LI-6800 measurements: 228 plants+two light gradients to better understand how invasive & natives respond to light environments. It's been great to have Jenna visiting from Clemson and contributing to our fieldwork efforts!

Our new paper is out in Ecosphere! 🪻🐝 Network rewiring and species turnover stabilize plant–pollinator interactions across habitats and seasons in dry forests on Caribbean Islands 🦋 esajournals.onlinelibrary.wiley.com/doi/10.1002/... Caribbean Pollination Networks Project-2026
En el Día Mundial de las Abejas, protegerlas es proteger nuestro futuro. Reducir el uso de pesticidas, cuidar sus hábitats y defender la biodiversidad no es opcional. Sin abejas, nuestros ecosistemas y nuestra alimentación estarían en riesgo. 🐝🌼 @ebdonana.bsky.social #WorldBeeDay #SaveTheBees
Using multiple lines of evidence, we show that feral cats and red foxes are strongly implicated in most Australian mammal extinctions and in the ongoing imperilment of numerous extant species. academic.oup.com/bioscience/a... A large collaborative effort to rebut Wallach and Lundgren (2025).
We are pleased to announce the 2026 cohort of ESA Excellence in Ecology Scholars!🌟 Congratulations to: - Diana Macias - Ana Carolina Prado-Valladares - Lis Regula - Julissa Rojas-Sandoval Learn about them in our announcement: https://ow.ly/xkmG50Y0MV1
Year 5 for our Caribbean Pollination Networks project is officially completed! 🌺🐝🦋 New species & interactions as we continue exploring the incredible diversity of Caribbean plants & their pollinators. So much more to learn from these dynamic systems! #TropicalDryForests #PlantPollinatorNetworks
21% of urban falcon deaths are caused by window collisions. 🪟 Birds struggle to see clear glass, adding markings or special films can make windows visible and save lives. 👉 Learn more with Environment for the Americas: https://www.migratorybirdday.org/
