An Investigation Into The Habitat, Behavior And Opportunistic Feeding Strategies Of The Protected Goliath Grouper (Epinephelus Itajara), Angela Collins May 2014

An Investigation Into The Habitat, Behavior And Opportunistic Feeding Strategies Of The Protected Goliath Grouper (Epinephelus Itajara), Angela Collins

Graduate Theses and Dissertations

Groupers (Epinephelidae: Epinephelinae) are apex predators within many reef communities worldwide. Grouper landings contribute significantly to global fisheries, and many populations are suffering from unsustainable levels of exploitation. The large size, site specificity and catchability of most groupers increase susceptibility to fishing pressure, and a large number of grouper species throughout the world are currently overfished. Multiple species are listed as endangered or threatened, and many have suffered local extirpations across their range. Removal of these upper level predators can significantly alter community structure and result in second order effects that may have critical ecological implications. The economic and ecological ...

Iowa Agricultural Educators' Current Grading Practices And Perceptions Of Standards-Based Grading, Jenny Ann Lichty Jan 2014

Iowa Agricultural Educators' Current Grading Practices And Perceptions Of Standards-Based Grading, Jenny Ann Lichty

Graduate Theses and Dissertations

Research on grading reveals that grading practices have not changed much since they were first introduced. However, educators are now learning about a newer grading approach that evaluates student performance based on clearly defined learning standards. Standards-based grading (SBG) looks to more accurately communicate student knowledge by assessing and reporting each student's mastery based on clearly defined learning standards. While still rather new, research on standards-based grading is limited and very little has been conducted at the secondary level. Even less research has been conducted on SBG and grading practices of career and technical education teachers.

The purpose of ...
