Acoustic Sampling Of Arkansas Bat Species Richness Across Different Seasons And Habitats, Lark E. Sybrant

ATU Research Symposium

Arkansas is home to sixteen bat species belonging to the Vespertilionidae and Molossidae families. Bats are keystone species and provide numerous ecosystem services that also benefit people. This study explores factors that impact species richness between the spring and fall seasons in a wooded rural site (Washburn Park) and an urban field site (Arkansas Tech University campus), Russellville, AR. The non-invasive Echo Meter Touch 2 Pro, from Wildlife Acoustics, was used to record calls and identify bat species from these locations. Nearly 1,050 calls were recorded from 11 different species across the spring and fall between both sites. Results showed …

Environmental Factors Affecting Coleoptera Biomass In The Ozark Mountain Range In Arkansas, Hayley J. Springsteen

ATU Research Symposium

Abstract:

Terrestrial invertebrates including species of Coleoptera (beetles) play an important role in many ecosystem services including soil formation and fertility, pollination, decomposition and nutrient turnover, population regulation of other organisms through predation. Coleoptera are often vital in determining biodiversity and conservation techniques. The purpose of this study is to contribute to the knowledge of how environmental factors and different management practices are affecting Coleoptera populations and further assist ecologists in improving management techniques in the future. The insect data in this study was collected over the course of two weeks in the Arkansas portion of the Boston Mountain range. …
