spatial@ucsb.local2019: Posters

spatial@ucsb.local2019 main page The Future of Island Oaks The Future of Island Oaks Laura Wolf, Sofie McComb, Claire Powers, Jazmine Uy, Alyssa Winchell Bren School of Environmental Management, University of California, Santa Barbara Description: Island oak (Quercus tomentella) is a rare oak species endemic to six islands in the California Island Archipelago (CAIA). Over a century of farming and grazing on the islands degraded core habitat and reduced island oak seedling recruitment. The species was listed as endangered by the IUCN in 2016. Most historical threats have been removed, though island oak regeneration is still restricted and there is concern that impending climate change poses an additional threat that may ultimately lead to extinction. Spatially-constrained, if the island oak’s range shifts or further deteriorates, alternative options are limited. We used MaxEnt, a species distribution model, to identify island oak’s bioclimatic niche on Santa Cruz, Santa Rosa, and Santa Catalina Islands and then predicted where that niche might exist through the end of the century under four climate change scenarios. Model outputs supported three main findings: (1) Island oak’s predicted bioclimatic niche was largely driven by soil moisture availability; (2) Santa Rosa Island had the most predicted suitable habitat under each climate change scenario, while predicted suitable habitat on Santa Cruz and Santa Catalina Islands was minimal; and (3) the bioclimatic habitat occupied by island oak varies substantially between the three islands studied. Improvements in life history information, legacy grazing patterns, and more finely downscaled climate data would substantially increase model validity. Research should focus on identifying mechanisms driving the variation in habitat occupied on each island, while restoration should prioritize habitat augmentation and seedling recruitment, to increase island oak’s resiliency to climate change.   Urbanization and its Effects on the Surrounding Environment                       Urbanization and its Effects on the Surrounding Environment: Case Study of Beijing and Lanzhou, China Guiyu Li, Yingyi He, Jiaxuan Lyu, Hoayu Shi Department of Geography, University of California, Santa Barbara Description: In the past decades, China has experienced massive economic growth and urban development. Changes in urban land cover, vegetation healthiness, and temperature distribution are crucial factors to understand the urbanization effects on the surrounding environment. Beijing and Lanzhou, two distinctive cities in terms of size and geographical location, are selected as our study objects. Using Landsat 5 and 8 images from 1993 to 2017 for the two cities, we train our algorithms to classify land cover types, including urban, vegetation, soil, and water. Normalized Difference Vegetation Index (NDVI) is calculated to measure vegetation health. Temperatures are derived using the radiance of the thermal band. Land cover classes are used for NDVI and temperature analysis. Based...

Keynotes will be delivered by Mahnoosh Alizadeh (Electrical and Computer Engineering, UC Santa Barbara), Konstadinos (Kostas) Goulias (Dept. of Geography, UC Santa Barbara), and Kurt Shellhause (Water Resources Engineer, Kasraie Consulting). Representatives from the private sector and industry and campus-wide academics in the humanities, sciences, social sciences, and engineering programs will showcase how spatial thinking facilitates research and creativity. A total of 38 posters were submitted for viewing. See agenda, speaker bios and abstracts, and a sampling of posters above. The poster session will begin at 12:30 p.m. and lunch will be served in tandem. Lunch will continue to be served and posters may be viewed until 2:30 p.m. For planning purposes, we request that you RSVP to kdoehner@spatial.ucsb.edu before Thursday, May 30. We invite you, your colleagues, and your students to participate in this event as attendees to the plenary and/or viewers of the posters. We look forward to your participation and encourage you to share this invitation with others who may be interested in...

Limes – Who? What? When? Where? Why? A ThinkSpatial Recap

Mar 12, 2019 • Categories: Event | News | Recap | ThinkSpatial

The Spatial Center was glad to invite Grant McKenzie, one of Geography’s own graduates, back from the chill of Montreal for a visit and talk on March 5. Formerly from the STKO lab, Grant is interested in how geographic information has a role to play in the study of the the intersection of information technology and society and what we can understand about human behavior. At the Center, he presented some early exploration he and his group were doing on scooters as a form of public transportation. Here, he asked the audience if anyone frequently used Lime to get around (just one?!): This analysis led to a discussion about Lime’s function for users as a replacement for or adjacent to bike sharing and other form of shared economy transport means. One of the takeaways? It looks like (in DC) bikes are used for commute (such as to and from work), whereas scooters are used for quick, short trips (average duration of just 5 minutes!)....
