Savanna chimpanzees adjust sleeping nest architecture in response to local weather conditions

Risk-sensitive foraging in savanna chimpanzees

Displaying local weather conditions through LEDs

The goal of the project was to create a method of displaying local weather conditions on the robots in the UT CS Department’s segbots, specifically through the use of communication between a Python script and an Arduino connected to Pololu LEDs. Specifically, this resulted in the presentation of specifically the temperature in the Austin area. While the goal of the project was technically accom...

Nest composition and yolk hormones: do female European starlings adjust yolk androgens to nest quality?

The nest is a key element of avian reproductive fitness. It provides the developmental environment for the embryo and nestling thereby affecting their quality and survival. Nests are often constructed by the male and nest quality, elaboration, and ornamentation vary among males in a species. Therefore, male nest-building behaviour is likely under sexual selection and females may use male nest-b...

Do "savanna" chimpanzees consume C4 resources?

Several stable carbon isotopic studies have shown that South African australopiths consumed significant quantities of C(4) resources (tropical grasses, sedges, or animals that eat those foods), but relatively little is known about the consumption of such resources by chimpanzees. Here, we present stable carbon isotopic data for 36 chimpanzee hair samples from Fongoli, one of the driest and most...
