Infectious diseases can cause rapid population declines or species extinctions. Many pathogens of terrestrial and marine taxa are sensitive to temperature, rainfall, and humidity, creating synergisms that could affect biodiversity. Climate warming can increase pathogen development and survival rates, disease transmission, and host susceptibility. Although(More)
Disease outbreaks alter the structure and function of marine ecosystems, directly affecting vertebrates (mammals, turtles, fish), invertebrates (corals, crustaceans, echinoderms), and plants (seagrasses). Previous studies suggest a recent increase in marine disease. However, lack of baseline data in most communities prevents a direct test of this(More)
nfectious diseases have recently caused substantial community and ecosystem-wide impacts in marine communities. A long-spined sea urchin disease virtually eradicated urchins from the Caribbean and facilitated a coral to algal shift on many reefs (Hughes et al. 1994). Coral diseases , such as white band (Figure 1), white plague, white pox, and aspergillosis(More)
This paper describes a progressive scaffolding approach for the design of web-based learning systems, as well as the development and evaluation of a prototype system that covered web development. Three levels of scaffolding were used: text, graphics, and video. A usability analysis of students' performance with the system found: a) Students primarily relied(More)
This article describes the ethical principles of autonomy, beneficence, and justice within the nurse researcher-participant relationship as these principles relate to the informed consent process for research. Within this process, the nurse is confronted with a dual role. This article describes how nurses, who are in the dual role of care provider and(More)
Diabetic nephropathy remains an area of high unmet medical need, with current therapies that slow down, but do not prevent, the progression of disease. A reduced phosphorylation state of adenosine monophosphate-activated protein kinase (AMPK) has been correlated with diminished kidney function in both humans and animal models of renal disease. Here, we(More)
