As Andy Papale said, we have a bunch of papers with both rats and mice on the #RestaurantRow task. (The data is all in https://www.nature.com/articles/s42003-022-04235-6, and publicly available.) Generally, we talk about similarities, but mice learn slower. Rats show the transition from wait zone to #precommitment in the offer zone in a few days, while mice take a lot longer.
Another space where I think there have been rat and mouse comparisons (although I don't find any explicit comparisons) is in the place field stability literature. My memory is that Cliff Kentros had really cool data on (#PlaceCell) #PlaceField stability as a function of #hippocampus #dopamine levels and task. (https://www.nature.com/articles/s42003-022-04235-6) Rats tended to live on the high-DA (place cells are stable) side while mice tended to live on the low-DA (place cells are unstable) side. But both could be manipulated with tasks and #dopamine (ant)agonists. I don't know if anyone explicitly looked at this.
Computationally parallel ‘change-of-mind’ tasks in mice, rats and humans are analysed and demonstrate that sensitivity to sunk costs during re-evaluation depends on the awareness of time spent and remaining.
“Biological Cycle”
Somewhat inspired by wasps, who tend to lay their eggs in anything that moves, including tarantulas.

A polar bear found dead on Alaska’s North Slope is the first of the species known to have been killed by the highly pathogenic♦️ avian influenza ♦️that is circulating among animal populations around the world.
The polar bear was found dead in October near Utqiagvik, the nation’s northernmost community, the Alaska Department of Environmental Conservation reported.
“This is the first polar bear case reported, for anywhere,” said Dr. Bob Gerlach, Alaska’s state veterinarian.
As such, it was reported to the World Organisation for Animal Health and has gotten attention in other Arctic nations that have polar bears, he said.
This was also the first Endangered Species Act-listed animal in Alaska known to fall victim to the disease.
Polar bears, dependent on sea ice that is diminishing because of climate change, were listed as threatened in 2008.
While polar bears normally eat seals they hunt from the sea ice, it appears likely that this bear was scavenging on dead birds and ingested the influenza virus that way, Gerlach said.
Numerous birds on the North Slope of various species have died from this avian influenza, according to the Department of Environmental Conservation.

What are your fave sci-fi tales dealing with cross-species friendships? Writers, what have you written?

New review on the “spatial cells” across different species! Looks very interesting:
Neural mechanisms for spatial cognition across vertebrates
Vinepinsky & Segev 2023
Small but important comment: it is perfectly normal for place cells to have multiple #PlaceFields ! Only in very small environments (<80cm diameter) will you mostly see single-field place cells. The single field is probably more the exception than the rule in the natural world.
