Big picture: large animals don't just move nutrients, they move microbes and restructure food webs from the bottom up. As megafauna decline, we're losing ecosystem functions we've barely begun to describe.

More wildlife = more multichannel feeding across detrital and algal pathways. At high input sites, river flow barely affected consumer diets...hippo subsidies may buffer the food web against hydrological variation.

Finally, @baileywallace.bsky.social and colleagues show that temperate and filamentous bacteriophages are significantly associated with stony coral tissue loss disease, a disease of unknown pathogen. Lysogenic conversion would make it really hard to detect pathogens! www.biorxiv.org/content/10.6...

“I honestly believe our most powerful position in a toxic time that feeds on cynicism, apathy, and despair is to genuinely care and act for a better world.”

“Cynicism is our enemy. We should check it, incl. on the left. It's not intellectually superior. It's the virus they're trying to infect us with. NO”

It is perfectly legal to know your rights and to educate others about them, too. EVERYONE in the United States, citizen or not, has rights. I will not allow this administration to intimidate us from helping you know about them. Here’s our shareable guide ⬇️: (pt. 1/2)
KNOW YOUR
RIGHTS
IN CASE OF ICE:
CONOCE TUS DERECHOS
EN CASO DE ENCUENTRO CON ICE:DO NOT OPEN YOUR DOOR.
ICE cannot enter your home without a warrant signed by a judge.
Tell the agents to show you the warrant by sliding it under the door.
NO ABRAS TU PUERTA.
ICE no puede entrar a tu casa sin una orden firmada por un juez. Diles a los agentes que te muestren la orden deslizándola debajo de la puerta.ASK THEM
TO LEAVE.
If ICE doesn't have a warrant, tell them you do not consent for them to enter your home and ask them to leave. At work, ICE cannot enter employee-only areas without permission.
2
PÍDALES QUE SE VAYAN.
Si ICE no tiene una orden judicial, diles que no das tu consentimiento para que entren a tu casa y pídeles que se vayan. En el trabajo, ICE no puede ingresar a áreas exclusivas para empleados sin permiso.REMAIN SILENT.
You have the right to remain silent.
If the agents ask you questions, tell them,
"I wish to remain silent."
PERMANECE EN SILENCIO.
Tienes derecho a permanecer en silencio.
Si los agentes te hacen preguntas, diles:
"Deseo permanecer en silencio".
