20 questions
Question 1: Amphibian larvae exposed only to low levels of pesticides exhibit a suppressed immune response.
A. Ano
B. Ne
Explanation: Kiesecker (2002) demonstrated that amphibian larvae exhibited a suppressed immune response when exposed to both R. ondatrae cercariae and low levels of pesticides, compared to those exposed only to the parasite. The materials do not state that pesticides alone suppress the immune response.
Question 2: According to the study materials, how do phosphorous-rich ponds contribute to the observed increase in amphibian limb deformities?
A. They lead to higher algal production rates, which supports increased population densities of the snail intermediate host.
B. The high phosphorous levels directly mutate amphibian DNA, causing limb malformations.
C. They create conditions that decrease the survivorship of the trematode parasite, thereby increasing amphibian exposure.
D. They provide more watering holes for cattle, which directly infects amphibians with Ribeiroia ondatrae.
Explanation: The study materials state that 'deformity hotspots' tended to be phosphorous-rich farm ponds with high algal production rates. These conditions supported high population densities, growth rates, and reproduction rates of the snail intermediate host. Higher snail densities are then associated with increased Ribeiroia ondatrae intensities in amphibians, leading to more deformities.
Question 3: The impact of pollutant stress on amphibian parasite communities has recently become a focus of research.
A. Ano
B. Ne
Explanation: The study materials state, "it perhaps comes as no surprise that the impact of pollutant stress on amphibian parasite communities has become a recent research focus".
Question 4: What specific type of environmental impact on amphibians was investigated by King et al. (2007) concerning parasite communities of the northern leopard frog?
A. Acidification of rivers due to industrial pollution
B. Nutrient loading and eutrophication in the Great Lakes
C. Agricultural land use practices and runoff into wetlands
D. Changes in myxozoan faunas in spottail shiners due to sewage effluent
Explanation: The study materials state: 'The comprehensive study by King et al. (2007) of the impacts of agricultural land use practices on parasite communities of the northern leopard frog is a case in point.' It also mentions 'Wetlands provide crucial habitat for amphibians and these vital habitats are increasingly becoming more fragmented, as well as being subjected to agricultural runoff.'
Question 5: The study materials indicate that the general life cycle of Apicomplexa is discussed.
A. Ano
B. Ne
Explanation: The study materials list 'life cycles Apicomplexa, general' as an entry, indicating that this topic is covered within the provided context.
