Patrick Lemons, Ph.D.
Patrick Lemons is the Assistant Regional Administrator of the Alaska Climate Adaptation Science Center (AK CASC), one of the nine regional centers that form the National and Regional Climate Adaptation Science Center Network. This position was formerly known as "Deputy Director".
Prior to joining the Alaska Climate Adaption Science Center, Patrick Lemons worked for U.S. Fish and Wildlife Service’s Marine Mammals Management program in Alaska where he served as a quantitative population ecologist from 2010 to 2016 and served as the Chief of the Marine Mammals Management program from 2016-2023. Much of his past work has included the use of novel quantitative approaches for addressing a variety of wildlife management needs. This includes the development of the first comprehensive estimate of the Pacific walrus population using a genetics based, capture-mark-recapture approach and through the use of integrated population models. He also specializes in program management and working with managing agencies to identify high priority science needs for numerous northern species including polar bears, Pacific walruses, sea otters, and migratory birds such as geese and loons.

Science and Products
Estimating Pacific walrus abundance and survival with multievent mark-recapture models
Arctic marine ecosystems are undergoing rapid physical and biological change associated with climate warming and loss of sea ice. Sea ice loss will impact many species through altered spatial and temporal availability of resources. In the Bering and Chukchi Seas, the Pacific walrus Odobenus rosmarus divergens is one species that could be impacted by rapid environmental change, and thus, population
Genetic variation in sea otters (Enhydra lutris) from the North Pacific with relevance to the threatened Southwest Alaska Distinct Population Segment
Demography of the Pacific walrus (Odobenus rosmarus divergens) in a changing Arctic
A likelihood-based approach for assessment of extra-pair paternity and conspecific brood parasitism in natural populations
Egg size matching by an intraspecific brood parasite
