We are testing a new system for linking grants to scientists.
The funding information displayed below comes from the
NIH Research Portfolio Online Reporting Tools and the
NSF Award Database.
The grant data on this page is limited to grants awarded in the United States and is thus partial. It can nonetheless be used to understand how funding patterns influence mentorship networks and vice-versa, which has deep implications on how research is done.

Dissertation Research: Male Testosterone Response to Courtship in the Monogamous California Mouse: An Honest Signal of Paternal Quality? @ University of Wisconsin-Madison
How animals choose mates is one of the most important questions in biology, because these decisions can shape the evolution of a species. Pressure to select a good mate may be particularly strong when an animal will have only one mate in a lifetime, or survival of infants depends on both parents. This project focuses on the relationship between male testosterone (T), courtship behavior and fathering behavior in the California mouse, Peromyscus californicus. California mice are unusual for mammals because fathers help mothers raise offspring, who cannot survive without their father's presence. Work with fish and birds has shown that females of other species sometimes prefer mates who can signal that they will be good fathers, but it is unknown whether the same is true for mammals. This proposal expands upon previously collected data by the same researchers that show that the amount of T a male releases when he is introduced to a female predicts aspects of his potential as a good father. The goal of the proposed project is to determine whether females can detect the amount of T a male releases during courtship, and if females prefer males who release the most T and advertise this trait using vocal communication. These studies will further an understanding of how species form mating preferences, and strengthen the concept that paternal care can be an important resource for females to consider during mate choice. Moreover, exploring the relationship between T and paternal care in the California mouse will further a more general understanding of how the neuroendocrine system functions to support fathering behavior in mammals, which has the potential to extend to human parenting. Vocal recording techniques from this project will be used in a laboratory module for students enrolled in an undergraduate course in behavioral neuroscience.
