Description
With 2016 marking the 100th Anniversary of the National Park Service (NPS), important discussions regarding the future of America's beloved parks and respective government funding must take place. Imagine all the money, including tax revenue, flowing through America's national parks system, and where is that money destined for in the future? National park funding will factor greatly into determining the future of America's NPS and individual parks. Therefore, it is imperative to investigate where and how government funding, for the present and future, is distributed throughout the parks protected under the NPS. Through personal experiences as a child, national parks consistently provide a unique exposure to and an education of the natural world, which are rare finds when growing up in suburban or metropolitan regions. Narrowing down, this analysis will focus on government disbursements to Yellowstone National Park (Yellowstone) and Isle Royale National Park (Isle Royale) with specifics on two budgeted projects crucial to park survival. Yellowstone and Isle Royale each request funding for a project crucial to the park's ecosystem and a project intended to improve guest services for visitors. Closing comments will provide recommendations for Yellowstone, Isle Royale and the NPS, including effects of President Trump's 2018 Government Proposed Budget, in an attempt to offer forward thinking about national parks. The projects and respective funding as detailed in this analysis have a forward-thinking focus as other projects included in the NPS requested funding budgets consider as well. Current actions and efforts are crucial to the long-term life and of this country's national parks for future generations to come.

Description
Desert environments provide considerable challenges to organisms because of high temperatures and limited food and water resources. Accordingly, desert species have behavioral and physiological traits that enable them to cope with these constraints. However, continuing human activity as well as anticipated further changes to the climate and the vegetative community pose a great challenge to such balance between an organism and its environment. This is especially true in the Arabian Desert, where climate conditions are extreme and environmental disturbances substantial. This study combined laboratory and field components to enhance our understanding of dhub (Uromastyx aegyptius) ecophysiology and determine whether habitat protection influences dhub behavior and physiology.
Results of this study showed that while body mass and body condition consistently diminished as the active season progressed, they were both greater in protected habitats compared to non-protected habitats, regardless of season. Dhubs surface activity and total body water decreased while evaporative water loss and body temperature increased as the active season progressed and ambient temperature got hotter. Total body water was also significantly affected by habitat protection.
Overall, this study revealed that, while habitat protection provided more vegetation, it had little effect on seasonal changes in surface activity. While resource availability in protected areas might allow for larger dhub populations, unprotected areas showed similar body morphometrics, activity, and body temperatures. By developing an understanding of how different coping strategies are linked to particular ecological, morphological, and phylogenetic traits, we will be able to make more accurate predictions regarding the vulnerability of species. By combining previous studies pertaining to conservation of protected species with the results of my study, a number of steps in ecosystem management are recommended to help in the preservation of dhubs in the Kuwaiti desert.
