About The Cover
The images show resting juveniles of the Mindanao treeshrew (Tupaia everetti)—an endemic, nonvolant mammal species found in the Mindanao Faunal Region in the Philippines—inside the nest cavity of a dead pandan tree (Sararanga cf. philippinensis) in a curled, tight ball position covered by shredded leaf litter, as well as in a ventral position where the tail is on top of the belly. The recent study by Senarillos and Ibañez (2023) described, for the first time, the nest architecture and nest site characteristics of T. everetti based on a single active nest documented from Dinagat Islands. This nest discovery is a valuable contribution to the minimal existing literature about this poorly studied species, which may be increasingly threatened by anthropogenic impacts. As such, the authors highly recommend more nest search and breeding ecology studies on Dinagat Islands and other areas where T. everetti is found to determine if the nesting pattern is similar to what was discovered in the study.
