Ecosystem Damage Leading to a Possible Human Extinction
Get PDFWhile there are many factors that could lead to possible human extinction, the interaction between humans and the planet is something that needs to be monitored and changed, in order to prevent any more harm to the environment. By shaping the ecosystem and environment in a way that only benefits humans, there has been a tremendous loss of biodiversity. This will affect humans’ way of life. As everything is connected, it is important to understand the risks of how humans are treating the planet, so conservation efforts can be implemented based on the current state of the environment

The Effects of Intrinsic Cognitive Load on Student Learning in Managerial Accounting
No full textThis study investigates whether reducing students’ Intrinsic Cognitive Loads (ICL) improves student performance in Managerial Accounting, a core introductory accounting course. The purpose of the study is not to compare accounting and non-accounting majors’ learning. The goal of the study is to determine whether overall student learning improves by only focusing on instructional material that is needed by non-accounting majors in the course. Intrinsic Cognitive Load refers to the innate level of difficulty associated with an instructional topic. Cognitive Load Theory (CLT) posits that high levels of ICL negatively affect learning. To date, empirical research supports this premise for novice students enrolled in introductory accounting courses. The present study reduces students’ ICL in Managerial Accounting by removing instructional material not deemed to be essential to non-accounting majors in an effort to improve overall student learning in the course. The course was presented in three modules, with three exams administered after each module to assess students’ learning. Instructional material was removed for the second and third modules only (the independent variable manipulations), since material covered in the first module is critical to all students’ success
FISHES OF THE CYPRESS CREEK SYSTEM, TENNESSEE RIVER DRAINAGE
Get PDFCypress Creek is a northern tributary to the Tennessee River (Pickwick Lake) in Lauderdale County, Alabama, and Wayne County, Tennessee, with a drainage area of 214 square miles. Although repeatedly sampled for fishes such as Slackwater Darter, Etheostoma boschungi, Tuscumbia Darter, E. tuscumbia, and Flame Chub, Hemitremia flammea, over the past several decades, the last comprehensive fish survey of the watershed was conducted in 1971, and changes in the fish fauna and community composition may have occurred. Historical data (1845‐ 2019) containing 5,105 records was compiled for 109 species reported at least once from the Cypress Creek system. Samples from 2009‐19 (primarily in 2015‐16) at 83 localities were collected by seining, backpack electrofishing, and a limited number of boat electrofishing efforts. Community composition was analyzed for 39 collections using the Index of Biotic Integrity. One hundred thirty‐one collections yielded 2,453 records containing a total of 80 species, with a mean of 21 species per collection, including several species of interest. Multiple species (e.g., Pirate Perch, Aphredoderus sayanus) that were rare in historical collections were proportionally documented more frequently in this study when sampling appropriate habitats in select tributaries. The current fish fauna of Cypress Creek includes 99 species, which represents high species diversity for this relatively moderate‐sized stream, when compared to rivers and streams frequently referenced for their fish diversity. Index of Biotic Integrity scores varied among tributaries, suggesting differing anthropogenic impacts on fish community composition across the watershed. Future development within the watershed should be closely monitored to ensure the aquatic biodiversity of this stream is not compromised
