Dr. Jeff Stetz is a research ecologist who specializes in the development and application of advanced population monitoring tools to both answer general ecological questions and to inform conservation and management of large mammals. His recent work uses detection data of grizzly and American black bears in the Glacier National Park region in conjunction with spatially-explicit capture-recapture (SECR) statistical methods to help explain the variation in seasonal density patterns of these sympatric (overlapping in space) species. The SECR modeling framework and the relatively large size of the datasets required a tremendous amount of computational capacity, with some single models requiring several weeks to converge. Without the large amount of RAM, multiple cores, and processing speed, these analyses would have been impossible.
The researchers at Montana Natural Heritage Program deployed a network of ultrasonic acoustic detector/recorder stations at more than 75 sites in the past 6 years. Each detector recorded nightly bat passes across all seasons. As of August 2017, over 10 million full spectrum sound files have been recorded, totaling over 50 TB of call data. In order to efficiently interpret these data, they use software to complete automated analysis of recorded bat calls. This software examines and measures hundreds of attributes of the echolocation calls in each sound file and assigns tentative species identification to calls when appropriate. Using the HPC, they were able to reanalyze millions of bat call files with the most up-to-date methods and this process was completed in days instead of years.
Ecohydraulics is a term that refers to the study of the interface between ecological systems and computations involving hydraulics or fluid mechanics. Advanced finite-element or finite-volume methods have proven to be effective and desirable when this interface requires solutions of more detail than typical one-dimensional steady-state hydraulics. Ecohydraulics problems often involve the superposition of anthropogenic activity on sensitive riparian settings, habitat preservation or water quality goals often where species of concern are present. The researchers at Montana State University has a history of success in the use of Computational fluid dynamics (CFD) models to predict fish mobility challenges where fish encounter man-made structures. HPC cluster was utilized to process and interpret the fine grid CFD model of the steep-pass flume which allowed the estimation of time requirements for different CFD models and configurations.
