Integrating Genetic and Enviromental Data to Develop Species Distribution Mapsand predict climate change impacts: A Case Study on Tsetse Flies, the Vectors of Sleeping Sickness

Results of YCEI seed funding enabled the following grants to be leveraged towards a greater understanding of future distribution of tsetse flies as climate change renders some existing habitats less suitable and others more suitable for the vector in future climate scenarios.

A Case Where Climate Change Reduces Infectious Disease Transmission

One of the most feared consequences of climate warming is the potential expansion of tropical infectious diseases. However, for diseases that require intermediate hosts a warmer climate and the particular dynamics of the disease can actually reduce transmission in some cases. A recent study by Paull and Johnson describes one such scenario.  The authors examined a system in which freshwater snails are intermediate hosts for trematode…

Ecology and Evolution of Invasive Mosquito Disease Vectors. Phil Lounibos

Phil Lounibos reviews the evolutionary history and competitive displacement between two mosquito species, Aedes aegypti (Yellow Fever Mosquito) and Aedes albopictus, (Asian Tiger Mosquito), responsible for the spread of Dengue Fever and chikunguya, two of the world’s most problematic diseases.  The final third of his talk looks at a recent field study in Rio de Janeiro to consider what the impact of the competition between species is on the transmission of Dengue.

Meteorological Influences on Lyme Disease

Over the past two decades Lyme disease has emerged as the most common vector-borne disease in the United States. It is currently endemic in at least 12 states, from Virginia in the South to Maine in the North, and Minnesota and Wisconsin in the West. The majority of cases are believed to be transmitted by nymphal ticks during late spring and early summer months of June, July, and August. Control methods currently focus on the…

Climate Impacts on Sanitation in Botswana

Worldwide, about 800 million people lack access to an improved water source. In its most basic form, an improved water supply is a well or protected spring that protects water from outside contamination. Lack of access to clean water helps explain why15% of all deaths of children under 5 worldwide are caused by diarrheal diseases. While many factors are involved, water quality and quantity…

Using multidisciplinary complex systems methodologies to better understand the linkages between water, health and climate change in developing countries.

Jonathan Mellor uses multidisciplinary complex systems methodologies to better understand the linkages between water and health in developing world countries.  A Virginia native, he took this approach for his doctoral research working under Prof.

Excessive Winter Deaths. Don't Expect Reductions From Global Warming

A presumed benefit of global warming is the assumption that warmer winter temperatures might decrease excessive winter deaths (EWDs) common in temperate climates. EWDs are defined as the difference between the number of deaths in a region during winter months (December – March) and the average of the proceeding fall and subsequent spring deaths. EWDs are attributable to a number of factors including higher incidences of cardio-respiratory and infectious diseases along with colder temperatures and icy conditions that can cause hypothermia and accidental falls.
