Summary: This article presents the findings of a multimethod archaeometry study on a sacrificed spider monkey in the ceremonial center of Teotihuacan, Mexico, indicating the occurrence of a diplomatic gift exchange with the neighboring Maya civilization. The study sheds light on the early interregional diplomacy between Teotihuacan and the Maya, suggesting a reconsideration of Teotihuacan's militaristic involvement at certain Maya sites. The research also reveals details about human-primate interaction, such as age at capture and transport, captive duration, anthropogenic diet, and context of sacrifice.

Summary: The center of mass (CoM) plays a crucial role in balance and motion in dogs, but its relationship with subject morphometrics is poorly understood. This study aimed to estimate the variance of CoM in a heterogeneous population of dogs and describe its relationship with subject morphometrics. It was found that dog length was the primary variable affecting the three-dimensional CoM, and a CoM-based normalization procedure should be considered to minimize outcome measure variations in dogs with different body types.

Summary: Foster care programs in animal shelters are important for animal welfare, disease risk reduction, and creating more space for incoming animals. However, little is known about why people volunteer as foster caregivers for shelter animals. This study surveyed foster caregivers in the United States to evaluate their motivations and expectations. The study found that the most common motivations were animal- and community-related, and younger caregivers were more likely to expect companionship, emotional support, and community connections through fostering.
