Multiple Responses By Cerulean Warblers To Experimental Forest Disturbance In The Appalachian Mountains, Than James Boves
Multiple Responses By Cerulean Warblers To Experimental Forest Disturbance In The Appalachian Mountains, Than James Boves
Doctoral Dissertations
The Cerulean Warbler (Setophaga cerulea) is a mature forest obligate and one of the fastest declining songbird species in the United States. This decline may be related to a lack of disturbance within contemporary forests; however, the consequences of disturbance on the species have not been rigorously evaluated. Thus, we assessed multiple responses by Cerulean Warblers to a range of experimental forest disturbances across the core of their breeding range in the Appalachian Mountains. We quantified individual and population responses to these manipulations, and assessed the potential consequences of disturbance on the sexual signaling system. Male ceruleans were …

Masters Theses
Aggregative feeding is widespread in Lepidopteran larvae suggesting that this
behavior serves on adaptive function. Many studies of the potential benefits of
aggregative feeding in Lepidopteran larvae have been conducted. However, no studies
have directly examined the benefits of cryptic larvae being both chemically defended and
gregarious. Group feeding occurs disproportionately more in chemically defended
larvae than in larvae that have no chemical defense. Most of these larvae are cryptic
when they are most highly aggregated and most vulnerable to predation. In this study,
the benefits of group feeding in terms of decreased predation were explored in first instar
larvae …
