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.

hippos in a hippo pool

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.

A Gradient of Wildlife Subsidies Alters Riverine Food Web Structure Terrestrial subsidies play a key role in freshwater food web structure and ecosystem function. Animal-mediated subsidies in particular provide high quality resources that shape aquatic food webs. ...

In Freshwater Biology, Frauendorf et al. show wildlife subsidies restructure the Mara River food web. Fish shifted from 2% to 73.5% reliance on wildlife-derived resources along a hippo/wildebeest gradient. doi.org/10.1111/fwb.70208

Bioreactors on the Move: How Animals Contribute to Microbial Community Coalescence and Shape Ecosystem Function Animals are moving bioreactors, assimilating microbial taxa from the environment, which then undergo selective filtering in their gut. Animals then deposit this new microbial community back into the ....

In Environmental Microbiology, we argue animals are "mobile bioreactors"...ingesting environmental microbes, transforming them in the gut, and depositing novel communities back into the environment. Case studies from hippos, coral reef fish, and earthworms. doi.org/10.1111/1462-2920.70291

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...

Microbial Depletion Is Associated with Slower Cnidarian Regeneration Synopsis. Microbiomes play an important role in physiology and development in cnidarians, but how these communities influence tissue regeneration is poorly

Excited to share JK Da'Anoy's first dissertation chapter published in @sicbjournals.bsky.social! What started off as a side project morphed into great work!
"Microbial depletion is associated with slower cnidarian regeneration"
LOTS of wondergrads made this happen!

We have used uhaul’s ubox service twice. It’s the cheapest and has worked out well. Their units are small but you can add additional units for just a couple $100 and you don’t have to pay additional shipping fees.

To understand how climate change affects natural ecosystems we need to know how warming influences species interactions. In our newest paper we show that predator-prey interactions fundamentally change across latitude leading to context dependent effects of warming. 🧪

I think it's worth repeating plainly that a federal judge halted Musk's federal funding freeze nearly two weeks ago but funds are still very much being frozen in violation of the court order.
