Results: There was a strong positive relationship between woodpecker species richness and current tree cover and annual precipitation, respectively. Precipitation also showed a strong indirect effect on woodpecker richness via the effects on tree availability. Deep-time tree availability, Quaternary climate...

Past and Present Distribution of the Red-Cockaded Woodpecker Picoides borealis and its Habitat in the Ouachita Mountains, Arkansas Within the past 15 years, at least 41 and probably more active cavity tree clusters (or colonies) of Red cockaded Woodpeckers (Picoides borealis) have exis... Jo...
woodlands and shrublands for their food, shelter, and nesting needs. The more you study them, the more you will find the need to learn about all the other organisms they are in relationship with
Using an analysis of literature data and long-term monitoring data, we investigated cavity orientation and its relationship to reproductive success in the federally endangered (USA), cooperatively breeding red-cockaded woodpecker (Dryobates borealis; RCW). RCWs are particularly interesting for studies of...

Resin production in existing longleaf pine nest trees remained sufficient for continued use, whereas resin production in loblolly pine and shortleaf pine nest trees decreased through time, probably because of woodpecker activity at resin wells. For these latter tree species, breeding males switched to...
This study examines the relationship between native woodpecker predation and parasitism by the introduced parasitoids S. agrili and T. planipennisi . We established a cohort of parasitized larvae on select ash trees and then used screening to exclude woodpeckers from some sections of the tree. We...
The Canary Islands great spotted woodpecker Dendrocopos major canariensis is an endemic bird restricted to the Pinus canariensis forests of Tenerife and Gran Canaria. Classification tree models were applied to explore the relationship of the occurrence of this picid and habitat variables between two ...
Overall, this study found season of fire had little influence on the RCW population or the bird community as a whole; however, long-term studies are needed to better understand this relationship.Lauerman, SarahDissertations & Theses - Gradworks...
