Human-induced climate change is altering precipitation patterns in most parts of the world (Stocker et al., 2013). In the future, climate change will likely exacerbate droughts (Trenberth et al., 2014; Dai, 2012) and drastically increase the likelihood of floods throughout many parts of South America, Africa and southern Asia (Hirabayashi et al., 2013) …
Already endemic in over 110 countries, and with almost 50 million cases annually, dengue fever continues to spread. Incidences have increased almost 30-fold in the past 50 years. Although rarely fatal, the disease costs Latin America and the Caribbean around $2.1 billion annually. Being a vector-borne disease, it is spread by mosquitos that frequently lay their eggs in standing water that is common near households in many tropical countries. Previous research has shown that dengue fever exhibits seasonal patterns, which means that climate change might affect its spread.
This presentation will describe interspecific interactions and trait evolution associated with encounters in nature between Aedes aegypti and Aedes albopictus, the most important vectors of dengue and chikungunya viruses. Effects of larval competition on dengue transmission in nature will also be discussed.
Mosquito biology, especially ecology and behavior, is the focus of Phil Lounibos’s laboratory located in Vero Beach, Florida.
Climate scientists predict that climate change will lead to increased variability in precipitation over much of South America. Research by Carlton et al (2013) on residents of northwestern rural Ecuador who rely on streams and rivers for their drinking water shows how those changes might impact water quality and associated rates of diarrhea, a water-related disease which leads to approximately 1 million deaths of young children worldwide each year. The study further highlighted curious dynamics involving precipitation and water-borne disease.
Kevin Lafferty is an ecologist with the US Geological Survey. He is also adjunct faculty at UC Santa Barbara where he helps run the ecological parasitology research group and mentors a half dozen PhD students. His research interests include how infectious diseases interact with food webs, conservation, marine ecology, human health, climate change, and biodiversity.
Dr. Joseph Eisenberg will be giving a lecture entitled “Ecological and Social Determinants of Enteric Pathogen Transmission in Northern Coastal Ecuador: Towards effective and sustainable interventions” at the EMD Seminar Series on Thursday, October 3, 2013 at 12 pm in LEPH 115.
Joseph Messina is Professor of Geography and Acting Director of the Center for Global Change and Earth Observations at Michigan State University. He holds a Ph.D. in Geography from UNC- Chapel Hill (2001). He has worked in the Amazon, SE Asia, and East Africa on human – environment interactions, infectious diseases, and land change science. In Michigan, he explores issues related to health care access and recently co-authored a new standard for hospital services.
The American Security Project (2011) report estimates that failure to address climate change could result in a $22 billion hit in GDP and nearly 100,000 jobs lost in New England between 2010 and 2050. Some of the projected impacts of climate change, such as warmer temperatures, faster than global-average sea level rise, and erratic changes in precipitation and extreme events (such as hurricanes and snowfall events), are already being felt in New England.
