Spread of a virulent amphibian pathogen across the Sierra Nevada

Dr. Roland Knapp

 

Abstract: The global emergence of the amphibian chytrid fungus (Batrachochytrium
dendrobatidis: “Bd”) has caused the extinction of at least 90 frog species and the decline of
hundreds more. This impact has been called the most spectacular loss of vertebrate
biodiversity due to disease in recorded history. Bd is believed to have originated in Asia, but is
now distributed worldwide due to global commerce. In California’s Sierra Nevada mountains,
Bd emerged in the 1960s and subsequently spread across the range, causing precipitous
declines of the once-common mountain yellow-legged frog and its eventual listing under the
U.S. Endangered Species Act. Describing this spread, including identifying factors associated
with its arrival in frog populations, would allow better prediction of future spread and aid in the
identification of possible vectors. In this presentation, I will provide details on the patterns of
Bd spread in the Sierra Nevada and solicit input on how these data could best be analyzed.

Bio:
Roland Knapp is a research biologist at the University of California Sierra Nevada
Aquatic Research Laboratory. His research interests include the population and conservation
biology of endangered mountain yellow-legged frogs in California’s Sierra Nevada mountains,
and the community ecology of montane lake ecosystems. The landscape-scale surveys of
aquatic habitats in the southern Sierra Nevada (7,000+ lakes and ponds) that he led form the
basis for ongoing amphibian and lake recovery efforts in Sequoia, Kings Canyon, and
Yosemite National Parks, and beyond. His current research focuses on the recovery of
mountain yellow-legged frogs in the presence of the recently-emerged amphibian chytrid
fungus (Batrachochytrium dendrobatidis).

Inferring Network Structure and Flows using Partial Observations

Ambuj Singh

University of California Santa Barbara

12:00 p.m. Tuesday, January 21, 2020 | 3512 Phelps Hall (map)

Network

Abstract:

Predicting network structure and flows on edges is a precondition to effective planning and disaster response in critical infrastructure networks. I will summarize some ideas inspired by network science, physical modeling, and machine learning to determine this information from incomplete observations. Using both physical domain-specific and data-driven approaches, these algorithms address diverse problems including: the reconstruction of network topology and parameters, the estimation of network flows, the optimal selection and scheduling of multiple types of sensors, and the modeling of interdependencies in multilayer networks. The overall goal is to develop a rigorous theory for solving the inverse problem of edge and flow determination from observations of critical infrastructure networks.

The Geography of Forest Hydraulic Trait Compositions: Observed Patterns, underlying Mechanisms, and Future Implications

 

 

Anna Trugman

University of California Santa Barbara

12:00 p.m. Tuesday, March 17, 2020 | 3512 Phelps Hall (map)

 

ABSTRACT:

Tree hydraulic traits determine plant water use and tree vulnerability to drought stress, thereby affecting forest productivity and the movement of water between the land surface and the atmosphere. Here, I leverage an extensive trait database and a long-term continental forest plot network to map changes in community trait distributions and quantify “trait velocities” (the rate of change in community-weighted traits) for different regions and different forest types across the U.S. from 2000 to the present. I find evidence for shifts towards communities with more drought tolerant traits driven by tree mortality. I then review my ongoing work looking at the extent to which community trait compositional changes may buffer forest productivity and water fluxes in the near term from the effects of climate change.

Bridging Space and Place in Geographic Information Systems

Emmanuel Papadakis

University of California Santa Barbara

12:00 p.m. Tuesday, January 21, 2020 | 3512 Phelps Hall (map)

Abstract:

People refer, describe and interact with places; geographic information systems (GIS), however, are designed to visualize, process and analyze spaces. Both place and space are used to describe the geographic world, but each provides a different perspective. Place is an informal view framed by symbols, concepts and experience, whereas space is confined to the rigid digital world that adheres to mathematical formulas, data models and processes. Since digital systems have become a vital part of our lives, it is crucial to enable them to visualize, analyze and process the world as humans do. In this presentation, I will tackle a long-lasting question on whether spatial representation standards infused with semantics can create an adequate reflection of the geographical world as it is projected in the human mind. Using the concept of functions, I show how important aspects of place can be formalized and be integrated into GIS. Through examples on place-based search, I depict how a system can combine the processing and visualizing capabilities of machines with the sophisticated concept of place, contributing to the overall idea of a place-based GIS. Finally, I give some insights on further research that aims to incorporate emotions and similar concepts in the aforementioned formalization. Also, I propose the idea of an Algebra of Patterns, which focuses on innovative ways of conducting place synthesis, search, and discovery.

Multi-Scale Modeling and Analysis of Movement

Somayeh Dodge

University of California Santa Barbara

12:00 p.m. Tuesday, January 14, 2020 | 3512 Phelps Hall (map)

Abstract:

Movement is a complex multidimensional process that operates in a space-time-context continuum across multiple scales. Regardless of the context or entity type, movement happens through a series of embedded patterns at different granularities. Hence, the study of movement requires careful consideration and integration of all three forms of granularity (as in Kuhn (2012)): spatial (micro-steps to macro flows), temporal (high-frequency short-term events to low-frequency long-term processes), and thematic (individual movement to collective dynamics). This presentation reviews my ongoing work on synthesizing a multiscale model of movement through mining and integration of movement patterns at different granularities. Using movement ecology as an application, I show how multiscale analysis of trajectories are applied to identify patterns of movement at different frequencies and how these patterns can be combined in a multiscale model of movement to reconstruct trajectories.
