New maps show where mosquitoes will invade Ecuador’s Andes mountains

Posted on April 25, 2019

GAINESVILLE – Blood sucking insects such as the Yellow fever mosquito, Aedes aegypti, are more than just a nuisance in Ecuador, they also spread diseases such as dengue fever, chikungunya and Zika. A warming world means that public health officials must decide where to direct surveillance and mosquito control efforts not only today, but also […]

Social-Ecological Factors Drive Dengue and Mosquito Presence in the Galapagos

Posted on March 8, 2019

GAINESVILLE, FL – With its turquoise waters and abundant wildlife, Ecuador’s Galapagos Islands have long been a vacation dream of many. Tourist guides highlight playful sea lions and giant tortoises, but they do not talk about the mosquitoes. For the more than 30,000 people who live there, emerging epidemics of mosquito-borne disease such as dengue, […]

Women in Science on Ada Lovelace Day

Posted on October 9, 2018

In observation of Ada Lovelace Day (9 October), the ZSL journal Animal Conservation asked their female editors to reflect on what inspired them to become scientists. UF’s Dr. Sadie Ryan had this to say: What inspired you to pursue a career in science?

Temperature explains broad patterns of Ross River virus transmission

Posted on August 28, 2018

RYAN – Temperature explains broad patterns of Ross River virus transmission Marta Strecker Shocket, Sadie J Ryan, Erin A Mordecai Article first published online: 28 AUG 2018 eLife DOI: 10.7554/eLife.37762.001 ABSTRACT: Thermal biology predicts that vector-borne disease transmission peaks at intermediate temperatures and declines at high and low temperatures. However, thermal optima and limits remain […]

Temperature model predicts regional and seasonal virus transmission by mosquitoes

Posted on August 28, 2018

GAINESVILLE, FL – New model that accurately predicts patterns of mosquito-borne Ross River virus epidemics could help prepare for the impact of climate change. Scientists have built a model that predicts how temperature affects the spread of Ross River virus, a common mosquito-borne virus in Australia, according to a report in the journal eLife. The […]

Conservation Conundrum and Amphibian Disease

Posted on August 20, 2018

GAINESVILLE, FL – Amidst global amphibian population collapses, ranavirus causes up to 90% mortality in amphibians, undermining conservation efforts and wetland. restoration projects. In a recent study University of Florida Medical Geography researchers identified important variables to measure in assessments of ranaviral infection risk in newly constructed ponds which are important components of wetland restoration. […]

UF Researchers Refine Zika Transmission Models

Posted on August 15, 2018

GAINESVILLE, FL – A University of Florida Medical Geography researcher recently participated in a study that found that current estimates of Zika virus transmission vastly over predict its possible range. Temperature is a major driver of vector-borne disease transmission, but current transmission models rely on untested assumptions about life history of Zika infected Aedes aegypti […]
