What are colors for? Ideas from spiders and cats

One of the clearest examples of biodiversity is coloration, colors are everywhere! In a single forest we can see animals that vary from dull gray to bright yellow moving around next to each other. Why does this happen? Why don’t all animals have the same color? Spiders and cats might give us some ideas about that!

Fabian Salgado-Roa is a Stengl-Wyer Postdoctoral Scholar at UT Austin using a multidisciplinary approach, combining biogeography, field-based experiments, and genomic analyses, to study animal coloration and genetic connectivity across landscapes.

In accordance with UT policy our organization has some new rules to abide by to ensure the safety and protection of minors at Science Under the Stars events:

We at SUTS cannot take custodial responsibility for minors during our events. Parents, legal guardians, teachers, and/or designated adult chaperones must remain with minors at all times.

Specifically:

  • Only minors accompanied by a parent, guardian, or adult chaperone will be allowed to participate.
  • A parent, guardian, or adult chaperone must remain on-site for the whole duration of the event.
  • Dropping off minors without an accompanying adult is not permitted.
  • Minors who arrive unaccompanied will not be allowed to participate.
  • 18-year-old high school students are still considered minors under this policy and must also be accompanied.
