Environmental Sciences Seminar Series: Ecological Changes and the Development of Environmental Policies to Conserve Lake Tahoe
Dr. Sudeep Chandra is an Associate Professor of Limnology and Conservation Ecology at the University of Nevada, Rene. He is also the Director of the Castle Lake Environmental Research and Education Program which holds the longest running mountain lake ecology data set in North and South America. He served as a Director for the Ecosystem Sciences Program at the National Science Foundation. Sudeep graduated in 2003 with a Ph.D. in ecology from the University of California- Davis with Dr. Charles Goldman. As a postdoctoral Fellow at the Center for Limnology, University of Wisconsin- Madison he evaluated the restoration potential of salmonids and impacts of nonnative species in large river and lake ecosystems. He has classical training in limnology evaluating the impact of human disturbance (e.g. climate change, invasive species, nutrient loading, land use change) on freshwater ecosystems. Sudeep’s laboratory primarily focuses on how to restore and conserve aquatic ecosystems with a goal of providing scientific studies develop public policy from scientifically based investigations. They take an ecosystem-based approach and evaluate how invasive species alter water clarity, affect native species, and may prevent the restoration potential of native fishes such as Lahontan cutthroat trout. His graduate students have recently completed studies that predict how climate change and the modification of the nearshore environment at Lake Tahoe contribute to the spread of invasive species (largemouth bass, blue gill), the expansion of nonnative crayfish and their impacts to lake ecosystems, the potential for new invaders (New Zealand mudsnail, quagga mussel) to colonize the lake, and how quagga mussel is impacting the fishery and bottom ecology of Lake Mead.
Sudeep has been a strong advocate of cooperative international research and conservation. His interest in international research began in 1997 when he participated in the Tahoe-Baikal Institute environmental exchange. After this exchange he continued to study contaminant loading in the Selenge River Delta, Lake Baikal. In 2003, he codeveloped a research project that investigated the impacts of mining on the water quality and fisheries habitat in upper watershed of Lake Baikal in Mongolia. This work led to the development of a 5 year project to use faith based and scientific approaches to conserve the world’s largest trout in Mongolia. Through support from NATO he co led a project to improve protein sources for local communities via hatchery production in newly formed irrigation lakes in Uzbekistan. His current efforts through the US AID and State Department programs are to develop capacity to protect Central America’s largest lake, Lake Atitlan, by transferring scientific and policy information from the lakes in the Pacific Rim (Lake Tahoe and Crater Lake) to academicians and government institutions.

Managerial Ability and Credit Rating Change
12:00 - 1:30 p.m., Thursday, February 25, 2016Whitinger Building room 145, Hall of Fame Conference RoomRSVP before February 15, 2016
Presented by Kris KemperAssistant Professor of Finance
This study examines the relation between managerial ability and credit rating change. We predict that firms with more able managers are more likely to receive upgrades in their credit ratings. We find a significant and positive relation between managerial ability and change in credit ratings, suggesting more able managers can take effective actions to improve their credit ratings. However, we also find that small changes in managerial ability do not influence credit rating. Similarly, we find that changes in managerial ability do not alter Credit Watch warnings. We do find evidence to suggest that the ablest managers are able to recover a lost credit rating in the year following a downgrade.
