Predator foraging behavior and patterns of avian nest success: What can we learn from an agent-based model?

  • I studied the relationship between predators, nest dispersion, and nest success.
  • I built an agent-based model using data from nesting waterfowl, skunks, and foxes.
  • Predation risk is diluted when nests are clustered and predation is incidental.
  • When predators respond strongly to nest density, widely spaced nests survive better.
  • Habitat management that imposes nest clustering could create ecological traps.

How I used A / B testing to hack my kids

A/B testing is used to test one or more “treatments” or experiments over a “control” or the existing experience. A metric is measured, usually based on a user action such as a click through or “conversion” with a baseline against the control.

Sounds like science to me!

Study finds straightforward way to model growth of vein networks

October 3, 2016 by Patrick Ammerman

A new study by Eleni Katifori, an assistant professor in the Department of Physics & Astronomy of the University of Pennsylvania School of Arts & Sciences, and Henrik Ronellenfitsch, a postdoc in her lab, described how a simple rule guides the development of the vasculature in both animals and plants.
They used mathematical modeling to show that this rule, known as adaptive feedback, can produce the most efficient possible network of veins for any organism.
