Brood movements were inversely associated with arthropod abundance with greater brood movements occurring when arthropod abundances were low. Habitat factors positively associated with arthropod abundances were more forbs, more forb species/m2, and more grass species/m2. Restoration more often produced habitat structurally similar to brood rearing habitat than nesting habitat. However, availability of nesting habitat increased through time in restoration areas. Although restoration produced habitat that was structurally similar to brood rearing habitat, arthropod abundances were reduced by 63% in restored areas and I did not detect an increase in arthropod abundances between years in restored areas. Orthopteran biomass was reduced by 70% in restoration areas and was responsible for the differences in arthropod biomass. Restoration practices that produced habitat structurally similar to brood rearing habitat were a combination of burning, disking, and planting a variety of native warm season grasses. In contrast, planting or promoting development of a mono culture of grass species (regardless of native origin) did not produce habitat structurally similar to brood rearing or nesting habitat. Burn only treatments in fescue dominated fields produced approximately equal proportions of brood rearing and nesting habitat but brood rearing habitat changed into nesting habitat after only one growing season post treatment.

I radio collared and monitored 90 bobwhites on 15 privately-owned fields in Searcy County in 2008 and 2009. Twenty nests were located and nest success was compared between nests located in hayfields and non-hayfields. Vegetation was compared between nest sites and reference locations to characterize nesting habitat. Vegetation and invertebrate abundance were compared between sites in which broods foraged and reference sites in order to characterize brood-rearing habitat. Finally, I compared thermal characteristics between sites in which bobwhites foraged and reference sites. I intended to assess the ability of bobwhite restoration lands to supply nesting and brood-rearing habitat. I developed models which described nesting and brood-rearing habitat and used this model to classify vegetation samples from restoration areas as either one of the two habitat types or as unsuitable for either activity. A discriminant function used to discriminate between nest sites, foraging sites and unusable habitat correctly classified 68% of foraging sites, 75% of nest sites, 50% of transit sites, and 12% of reference sites. Sixty-five percent of restoration area samples were classified as foraging sites, 10% as nest sites and 25% as unusable. Although the discriminant function identified foraging and nesting habitat on restoration areas, bobwhite seldom used any of the restoration areas during the breeding season. Thus, restoration efforts appear to be ineffective in providing suitable habitat for breeding bobwhites. Low invertebrate biomass and abundance on restoration areas may play a role in lack of use by bobwhite. In restoration areas, habitat similar to nesting habitat was produced 2-4 years after burning of disking. Breeding habitat for bobwhites should contain both nesting and foraging habitat. Thus, management practices should provide both nesting and foraging habitat, with a majority of foraging habitat. As many of the fields that were heavily used by bobwhite were lightly to moderately grazed, I conclude that grazing at that level may be an appropriate management tool for bobwhite.

This book was released on 2001. Ecology available in PDF, EPUB and Kindle. This best-selling majors ecology book continues to present ecology as a series of problems for readers to critically analyze. No other text presents analytical, quantitative, and statistical ecological information in an equally accessible style. Reflecting the way ecologists actually practice, the book emphasizes the role of experiments in testing ecological ideas and discusses many contemporary and controversial problems related to distribution and abundance. Throughout the book, Krebs thoroughly explains the application of mathematical concepts in ecology while reinforcing these concepts with research references, examples, and interesting end-of-chapter review questions. Thoroughly updated with new examples and references, the book now features a new full-color design and is accompanied by an art CD-ROM for instructors. The field package also includes The Ecology Action Guide, a guide that encourages readers to be environmentally responsible citizens, and a subscription to The Ecology Place (www.ecologyplace.com), a web site and CD-ROM that enables users to become virtual field ecologists by performing experiments such as estimating the number of mice on an imaginary island or restoring prairie land in Iowa. For college instructors and students.
