We report presence of low levels of alkaloids in “undefended” poison frogs (Hyloxalus, Allobates, Leucostethus, Solverstoneia, Rheobates [!!], also Amazophrynella, Eleutherodactylus…) We provide a perspective about what this means for origins of chemical defense 1/5

Un hito extraordinario para la anfibiología Alcanzamos las 9000 especies de anfibios a nivel global. El número de especies aumenta gracias al trabajo de taxónomos en todo el mundo que descubren y describen nuevas especies. La lista completa está disponible en AmphibiaWeb: amphibiaweb.org

#CLH2026 NO DRINKS IN THE CLASSROOMS

#CLB2026 this captures my view of the Amazon too. 😍 From Sofía Granados Martínez’s talk in our poison frog symposium

Oscar Flores Villela estimates that the cost of describing a new species is between $8000 and $10,000 #CLH2026

Firma para detener la ampliación de la carretera que afecta al hábitat del Jambato c.org/MsWJwy7QJQ vía @ChangeorgLatino

Para evitar que la única población conocida de Jambato sea sacrificada por el atropello del populismo pseudodesarrollista de Lulu, se necesita de urgencia geólogo o ingeniero civil para asesorar acerca del uso de dinamita en la construcción de la carretera Angamarca - El Corazón

Atelopus ignescens (the jambato) is a sentinel for environmental health. Please help us protect it givebutter.com/XNVdrL If you are a geologist/engineer who could help advise on dynamite use for road construction pls DM me ASAP (urgent need)

Do I know any journalists interested in covering a story about a highway and the last population of a frog? Please message me. It is time sensitive

I am speaking at Joint Meeting of Ichthyologists and Herpetologists #JMIH25. Please check out my talk if you're here!

@ethanblinck If you email the ad to me I can forward to the uc berkeley mvz listserv

ad to come, but I'm looking for an M.S. student to work on conservation genomics of swift foxes on the American Prairie Reserve (MT) starting 9/1. this is a collab w/ Smithsonian & Justine Becker; strong candidates will have genomics experience and be up for remote fieldwork

In Ecuador, most reagents cost twice as much as they do in other countries. This is a hindrance to our scientific development. Perhaps manufacturers could help with price controls? @NEBiolabs En Ecuador la mayoría de reactivos cuestan el doble de su costo comercial en otros países. Es un freno a nuestro desarrollo científico. Será posible que los fabricantes ayuden con control de precios?
