External - Semester 2 - 2018
General Course Information
Course Code PLANT SC 7022EX Course Invasion Biology: Foundations of Biosecurity Coordinating Unit School of Agriculture, Food and Wine Term Semester 2 Level Postgraduate Coursework Location/s External Units 3 Contact External Available for Study Abroad and Exchange Y Course Description An understanding of invasion biology provides a foundation for the principles and practices of biosecurity. This course will consider case studies of insects, plant diseases and weeds that have invaded ecosystems. This will lead to a consideration of the ecological theory that applies to biological invasions, including colonisation and propagule pressure, population growth, predator-prey and pathogen host interactions, Allee effects and population viability, the factors that affect the spread of invasive species, and the genetics and evolution of founding populations. The biological and ecological factors that influence the impact of invasive species will be evaluated.
Course Coordinator: Emeritus Professor Michael Keller

Specific Course Requirements
The following texts and other resources are required in this course:
The course focuses on a series of modules that are delivered via MyUni or memory stick. Each module has (1) a PowerPoint lecture delivered using Articulate software, (2) a prepared reading 10-12 pages [excluding references], and (3) prescribed reading from the textbook, Invasion Biology by Julie Lockwood. Some lectures also include short videos of interviews with experts and others involved with invasions of plant pests. Access to MyUni and online journals through the Library is essential.
Students receive a course book and memory stick that has copies of the assignment, the major readings and selected papers.
Students have an opportunity to communicate with the lecturer and other students in an online discussion and via email.
The University's policy on Assessment for Coursework Programs is based on the following four principles:
- Assessment must encourage and reinforce learning.
- Assessment must enable robust and fair judgements about student performance.
- Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
- Assessment must maintain academic standards.
Assessment task Type of assessment Percentage of total assessment for grading purposes Hurdle
Outcomes being assessed/achieved Approximate timing of assessment Glossary of technical terms Summative 10% No 1,2,3,4,5 Major report Summative 45% No 1,2,3,4,5 Practical Report 1 Summative 25% No 1,2,3,4,5 Practical Report 2 Summative 20% NO 1,4,5
Description of Assessment:
* Glossary of technical terms (10%)
Students prepare a glossary of 25 technical terms that are used by biologists to describe and explain aspects of invasion biology. Students choose the terms, with at least one term chosen from each module.
* Major report: Analysis of the Biology and Invasive Potential of a Selected Organism (45%)
Students select an organism and a location, and then analyse the biological attributes and environmental interactions of the selected species to develop a sound understanding of either (1) its potential to invade the selected location or (2) an invasion that has occurred or is in progress. They are free to choose any plant, invertebrate animal or cellular microorganism (i.e., not a virus) and any country or region.
* Practical Assignment 1: Sampling and Surveillance (25%)
Students design sampling programs for selected plant pests to monitor them (1) at border inspections and on relevant traded goods, (2) following a hypothetical incursion to determine population size and spread, and (3) to validate eradication programs. This includes proposals for both statistical and methodological details of sampling. Students have to employ one of their proposed sampling methods and undertake a thorough analysis of the data, including application to the development of a sampling program.
* Practical Assignment 2: MaxEnt prediction of distribution (20%)
Students predict the potential distribution of a selected species using MaxEnt based on climatic data. They gain a general understanding of how the potential distributions of species are estimated.
All assignments are sent to the course coordinator via email.
Assessment tasks must be submitted by the stated deadlines. There will be a penalty for late submission of assessment tasks: the submitted work will be marked ‘without prejudice’ and 10% of the obtained mark will be deducted for each working day (or part of a day) that an assessment task is late, up to a maximum penalty of 50% of the mark attained. An examiner may elect not to accept any assessment task that a student wants to submit after that task has been marked and feedback provided to the rest of the class.
Grades for your performance in this course will be awarded in accordance with the following scheme:
M10 (Coursework Mark Scheme) Grade Mark Description FNS Fail No Submission F 1-49 Fail P 50-64 Pass C 65-74 Credit D 75-84 Distinction HD 85-100 High Distinction CN Continuing NFE No Formal Examination RP Result Pending
Further details of the grades/results can be obtained from Examinations.
Grade Descriptors are available which provide a general guide to the standard of work that is expected at each grade level. More information at Assessment for Coursework Programs.
Final results for this course will be made available through Access Adelaide.
The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.
SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.
The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
