Historically, least terns (Sterna antillarum) were one of the most common tern species in North America. However, population declines have resulted from direct and indirect anthropogenic pressures on their breeding and foraging habitat. Three subspecies of least terns have been described within the United States: California least tern (S. a....
The field of conservation genetics, when properly implemented, is a constant juggling act integrating molecular genetics, ecology, and demography with applied aspects concerning managing declining species or implementing conservation laws and policies. This young field has grown substantially since the 1980s following the development of polymerase chain reaction and now...
Background: A particular health inequity that has drawn national attention is obesity in persons with disabilities (CDC, 2011). Estimates suggest that as many as 80% of adults with mild to moderate intellectual disability (ID) are overweight or obese (Stanish & Draheim, 2005). Despite the benefits of being active (e.g. controlling...

The purpose of this study was to examine the evidence of construct validity for self-report with assistance from a secondary source as a measure of physical activity (PA) in adults with intellectual disabilities (ID) in free-living environments. Thirty-seven participants (21 females, 16 males) with mild to moderate ID aged 19-74...
The group of scientists that make up the Intergovernmental Panel on Climate Change found in 2007 that the warming of Earth’s climate is unequivocal and largely due to human activity. Earth’s climate has changed in the past, though the recent magnitude and pace of changes are unprecedented in human existence....
In order to increase life expectancy without long periods of morbidity, physical activity should be a component in every older adult's lifestyle. It is proven that regular physical activity can improve health and quality of life for older adults; however, the older population is one of the most sedentary populations...
In recent years, there has been an increased interest in accurately measuring physical activity levels with accelerometers. Two distinct approaches have been used to estimate physical activity levels with accelerometers are vertical axis activity counts and vector magnitude (VM). Although previous studies evaluated these two distinct approaches for individuals without...
Interior least tern (Sternula antillarum athalassos) populations and productivity have been declining in Indiana for the past ten years, which is thought to be the result of predation. Methods for protecting nesting Interior least terns include fence exclosures and artificial shelters for chicks, but their effectiveness is unknown. Each Indiana...
Greater degrees of insulin resistance are associated with increased rates of coronary artery disease (CAD) progression. However, the specific behavioral determinants of insulin resistance are not well known in patients with CAD. Although abdominal obesity contributes to insulin resistance, the extent to which abdominal obesity may modify the relationship between...
The Double-crested Cormorant (Phalacrocorax auritus) is a widespread, colonial, North American waterbird with bicoastal and inland distributions. Four subspecies have been described within North America corresponding to five geographic breeding regions: Interior and North Atlantic cormorants (P. a. auritus); Southeastern cormorants (P. a. floridanus); Alaskan cormorants (P. a. cincinnatus); and...
