Wednesday Nite at the Lab
press release: WN@TL goes hybrid both with Zoom and with in-person (Room 1111) presentations. The zoom registration link is still go.wisc.edu/240r59. You can also watch a live web stream at on YouTube.
On September 14 Ana Caroline Paiva Gandara from the Department of Genetics and the Morgridge Institute will speak on “Climate Change & the Consequences of Suboptimal Temperatures on Reproduction.”
Description: Changes in temperature have been reported worldwide due to climate change, as its effects on the behavior of animals. So, it has become urgent to investigate how temperature impacts reproductive traits, as gametogenesis and fertility. Insects are particularly sensitive to environmental temperatures because they cannot properly regulate their internal temperatures. These animals are extremely relevant due to public health, economical, and ecological reasons; they have representatives of disease vectors, agricultural pests, and pollinators. Despite the accumulated knowledge on the effect of temperature on insect reproductive fitness, cellular and molecular mechanisms are basically unknown. Studies on the effects of suboptimal temperatures on the reproduction of insects may pave the way for further research into the effects of climate change on gamete quality of cattle, and pollinators under adverse environmental conditions. I am going to present a brief history of the studies of the effects of temperature on insect reproduction, with a focus on the fruit flies as a model system, passing through temperature sensing systems and few data about my own research on the topic.
Bio: I was born in Brazil and have developed my whole scientific career at Federal University of Rio de Janeiro, Rio de Janeiro, RJ - Brazil. Most of my experience was studying biochemistry and redox metabolism of hematophagous insects, with a focus in NADPH-oxidase and mitochondria roles in the gut. Because of my early involvement with science, I could mentor many students, be on undergraduate committees and collaborate with different research groups, which has yielded me several publications as co-author. Since high school, I have often been attending and presenting posters at different national and international scientific meetings. I have also been involved with university outreach and science communication practices, as lectures in high schools, live events for the lay public, articles to diverse science communication media, and becoming a permanent volunteer in the traditional science museum “Espaço Ciência Viva” at Rio de Janeiro city, as a specialist monitor. From February 2018 to June 2022, I worked at the BMB department at Johns Hopkins Bloomberg School of Public Health as a postdoctoral fellow for Dr. Daniela Drummond-Barbosa. In July 2022, I started working as Assistant Scientist at Department of Genetics at University of Wisconsin-Madison and for Morgridge Institute for Research. Using the model system Drosophila melanogaster, I study the effects of thermal stress on gametogenesis. I want to pursue a career in academic research, as an insect stress physiology specialist.
