Dark-eyed Junco Research


These protocols are presented so that others may adapt and possibly improve upon them. Every effort was made to make them accurate, but in some cases they were a work in progress and should not be relied on without independent validation.

Sensitive Issues

We recognize and acknowledge that certain audiences may be offended by research on animals and note that throughout the research we have taken all possible measures to preserve the welfare of the birds and cause no undue harm or interference. We conduct our research under the oversight of a federally mandated animal care committee, and we hope that our findings will ultimately be helpful to the animals themselves by learning more about their natural history and how best to contribute to their conservation.

    We approach conceptual issues in evolutionary biology from an endocrinological perspective, noting that single hormones typically act on several target tissues and thereby mediate suites of correlated phenotypic traits. ...
  • Ketterson, Ellen D.; Nolan, Val Jr; Wolf, Licia; Ziegenfus, Charles (American Society of Naturalists, 1992-12)
    Hormones influence many aspects of organismal behavior, physiology, and morphol- ogy, and thus hormones may lie at the root of many life-history trade-offs. By manipulating hormones we can create novel phenotypes (i.e., ...
  • Ketterson, Ellen D.; Nolan, Val Jr (American Society of Naturalists, 1992-11)
    Because of their role in mediating life‐history trade‐offs, hormones are expected to be strongly associated with components of fitness; however, few studies have examined how natural selection acts on hormonal variation ...
