it's a fascinating question: we are working on this, thanks for flagging the paper

ScienceShot: Razor Clams Create Quicksand to Burrow Water-sediment mix reduces drag on bivalve shells

"Fluidizing" reduces the drag between sand grains & shell by as much as 90%, allowing our razor clam to move at a rate of 1 foot/minute straight DOWN into the wet sand.

Some sand is taken into the siphon, which is then ejected as a 'sploot.'

Pace of ecology drives the tempo of visual perception across the animal kingdom - Nature Ecology & Evolution Using phylogenetic comparative methods across 237 species from disparate phyla, the authors show that species with fast-paced ecologies have higher temporal resolution of perception.

Place cells in CA1 lack topographical organization of firing locations | PNAS Topography is a well-described and well-known concept for cortical organization in primary sensory and motor cortices of mammalian brains. Similar ...

A half-century old question may have its final answer. Using high-resolution #Mini2P microscopes, we find no evidence of local topography in #PlaceCells. Place fields of neighbouring cells are no more similar than those of randomly selected cells. 🧠🗺️ Out now in @pnas.org www.pnas.org/doi/10.1073/...

Behavioral biases drift in individuals.

• Drift happens on many timescales
• Drift rate depends on genetics and neuromodulators
• It might be adaptive for rapidly changing environments

Bang the Drumstick Slowly | Ian Frazier About 26 billion chickens occupy Earth, but apart from the lucky ones in backyards, most are condemned to the hellscape that is industrial farming.

“Chickens and other poultry comprise 70 percent of all birds by weight. Chickens are the most numerous farm animal. As a global tribe, human beings could be called the People of the Chicken.” —Ian Frazier

Inferring social structure and its drivers from refuge use in the desert tortoise, a relatively solitary species - Behavioral Ecology and Sociobiology Abstract For several species, refuges (such as burrows, dens, roosts, nests) are an essential resource for protection from predators and extreme environmental conditions. Refuges also serve as focal s...

Innate biases/predispositins vary in flexibility and strength. The figure shows examples of studied biases that vary in strength (more biased on the left, less biased on the right) and flexibility (less flexible on the left, more flexible on the right). This includes the gray goose rolling egg, aggressive biases against "red bellied" objects , flee responses to looking objects and orienting responses towards the see in turtle hatchlings on the left, and more flexible and "weaker" preferences for colours or transient preferences for certain motion dynamic on the right. Fixed-action patterns usually have low flexibility and high strength, while early predispositions are weak and plastic. The figure illustrates some innate biases described in the references indicated with specific numbers. Cues position along this spectrum should be interpreted qualitatively. The exact position on the horizontal axis is purely indicative, as predispositions depend on species and context, as shown in this article.

Curves that represent the success probability of a choice, as a function of number of valid cues (x axis), number of misleading cues (different curves), and synergy between cues (different column), bias strength (horizontal row) Success probability as a function of the number of valid cues, misleading cues, bias strength and cue synergy. The horizontal axis represents the number of valid cues, different line colours represent different numbers of misleading cues. Subpanel columns represent increasing levels of synergy (from λ = 1 for the additive model with no synergy, to synergy of 2). Subpanel rows indicate bias strength β.
