Thursday, October 28, 2021 - 1:00pm

Please join us for a seminar hosted by the Max Planck-Yale Center for Biodiversity Movement and Global Change, featuring speaker Dr. Christen Fleming.

BIO: Christen Fleming is a physicist, mathematician, and statistician by training, and is currently an associate research scientist at the University of Maryland College Park (UMDCP) Department of Biology and a research associate at the Smithsonian Conservation Biology Institute (SCBI) Conservation Ecology Center. Dr. Fleming develops complementary mathematical models, statistical analyses, and software packages for difficult to work with ecological data. Currently, his focus is on addressing conservation related questions with animal tracking data, but he also works on evolutionary models for phylogenetic data, among other topics. Dr. Fleming earned a Bachelor of Science in physics, mathematics and statistics from the University of South Alabama, and obtained his doctorate in physics from UMCDP. He has since held post-doctoral positions in biology at UMDCP and SCBI, working with Drs. Justin M. Calabrese, Bill F. Fagan, and Peter Leimbgruber.

ABSTRACT: Satellite tracking technology has brought about an explosion in the collection of animal tracking data. These data are used to inform a number of subjects, including population dynamics, animal behavior, and disease transmission. A key interest addressed by animal tracking data is how much physical space animals use. Unfortunately, the most commonly applied statistical methods for space-use estimation were never intended for high-frequency movement data. In fact, these methods exhibit counter-intuitive biases that actually worsen as data quality improves. Moreover, the biases are negative, which means that space-use requirements are being underestimated on average, which, in turn, propagates detrimentally into undersized conservation and management recommendations. In this talk, I explain these biases with statistical analogies and thought experiments. I also describe their resolution—modern statistical methods based on stochastic process models—with animations and empirical examples.

Dr. Fleming will also be hosting a workshop for MPYC researchers on the same day. Read more about that event here.

Thursday, October 28, 2021 - 4:00pm

Dr. Christen Fleming will be providing a 2-hour workshop to MPYC researchers and collaborators on Continuous-Time Movement Modeling, in addition to his seminar talk on October 28, 2021

ABSTRACT: Animal tracking data often come with substantial autocorrelation and location error that render classical analyses invalid and cause differential biases across studies, sites, taxa, and individuals. Continuous-time methods offer a solution to these challenges, but can be conceptually challenging and are often misapplied. This workshop will provide beginners with an introduction to important concepts, as well as hands-on experience using the R package ‘ctmm’, to apply advanced statistical methods to tracking data. Participants will learn how to fit continuous-time movement models to their tracking data, select the most appropriate movement model for their analysis, interpret model parameters, perform home-range analysis via autocorrelated kernel density estimation (AKDE), perform path reconstruction via occurrence distribution estimation, and distinguish between the different types of utilization distributions. 

We are open for applications to attend the workshop. Please note spaces are limited, and we may require a justification for your attendance.  To inquire about attendance, email us at ybgc@yale.edu

Thursday, November 18, 2021 - 3:30pm

Please join us for a seminar hosted by the Center for Biodiversity and Global Change, featuring speaker Dr. Mercedes Santos.

Dr. Santos is the National Director of Marine Protected Areas with the National Parks Administration of Argentina. She is responsible for the Argentinean penguin monitoring program, and her research focuses on various aspects of penguin population dynamics, particularly in the context of the conservation of Antarctic marine living resources.

Please check back soon for more information regarding Dr. Santos’s talk, and be sure to email ybgc@yale.edu to be added to our mailing list and be the first to hear about our upcoming seminars and events!
