Since bats are also ecosystem indicators, their growing presence could signify that the island continues to recover, and inform management by identifying high biodiversity areas and guiding restoration initiatives.This study used non-invasive, passive acoustic monitoring methods, and identified bat species on Santa Rosa Island by analyzing echolocation calls using wildlife sound analysis software. Objectives included investigating spatiotemporal variations and abiotic factors that influence bat activity indices. Preliminary results suggest that, on SRI, wind conditions significantly reduced bat activity by a factor of -0.11 (p-value = 0.0004) and that there is no association between lunar illumination and bat activity on SRI (p-value = 0.069). It was found that there is no correlation between wind speed and lunar illumination, nor a combined effect on the number of bats detected (p-value= 0.50). Analysis of spatiotemporal relationships indicate that the species composition of the sites were substantially different (p-value = 0.022). There was no significant difference in activity of migratory and resident bats at the nursery (p-value = 0.432); however, resident bats were more active at the bunkhouse (p-value = 0.016), which could be due to the different types of habitats offered at each site. This study detected 20 species of bats that have never been recorded on the Channel Islands, including threatened and endangered species. It is important to consider that acoustic detectors only register the number of times a bat triggers them, and do not provide a count of bat populations. Nevertheless, this data serves as a starting point for the manual identification of live specimens on the Channel Islands.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\">\n<p class=\"wp-block-paragraph\"><strong><a href=\"https:\/\/src.cikeys.com\/2024\/conference-schedule\/oral-presentations\/\">Oral Presentation<\/a><\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">10:45am <strong>\u2013<\/strong> 12:15pm<br>Del Norte 2530<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Biology<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Selene Lopez, Barbara Reque, Dr. Russel Bradley, &amp; Dr. Isaac Quintanilla Salinas The pollination and seed dispersal activities of bats are particularly significant on the arid Channel Islands due to their numerous endemic and endangered plant species, which were historically diminished by introduced grazing animals.
