Breeding status shapes territoriality and vocalization patterns in spotted owls
Dana Reid
Vocal territory defense can vary within a species due to many factors such as sex and breeding status, influencing territory size and thus population density across a landscape. Therefore, understanding what influences variation in territorial vocalizations can help to illuminate trade-offs between territoriality and other life history demands, which benefits our general understanding of animal ecology as well as helps to inform emerging passive acoustic monitoring approaches. Here, we investigated how sex and breeding status...

Insulin secretion from pancreatic β-cells is essential for glucose homeostasis. An insufficient response to the demand for insulin results in diabetes. We previously showed that β-cell-specific deletion of Zfp148 (β-Zfp148KO) improves glucose tolerance and insulin secretion in mice. Here, we performed Ca2+ imaging of islets from β‑Zfp148KO and control mice on both a chow and a Western-style diet. β-Zfp148KO islets demonstrate improved sensitivity and sustained Ca2+ oscillations in response to elevated glucose. β-Zfp148KO islets also...
