Teaching

Dr Gemmill's teaching interests lie primarily in the field of plant evolutionary biology, with specific interests in plant molecular systematics and conservation genetics of Pacific plants.

Undergraduate Level:

BIOL210 - Introduction to Genetics

This paper deals with genetics in the widest sense from the molecular and cellular to the applied and evolutionary.  Both prokaryote and eukaryote genetics are discussed with respect to DNA replication, gene expression and control, and the role of mutations at both the DNA and chromosomal levels. 

 

Applications of molecular genetics such as cloning, DNA sequencing, genetic engineering, DNA fingerprinting and antibody technologies are introduced.  An in depth treatment of Mendelian genetics and an introduction to quantitative genetics complete the paper.

The paper is seen as being of major importance to students of biology, irrespective of whether their interests are in metabolic and cellular processes, plant/animal genetic improvement, or ecological and evolutionary.

 

 

BIOL223 - Introduction to Plant Biology [click on the link to see what the students have been up to]

 

An introduction to the structure and adaptation of plants, diversity, principles of identification and classification and molecular information.  A general introduction to plants and the foundation paper for Level 3 and higher plant papers.

 

BIOL226 - Flora of Aotearoa/New Zealand

A paper for students interested in New Zealand's native and naturalised flora, with emphasis on identification of plants and plant systemics.  A two day field trip will be held as part of this paper.

At the end of this paper students will be familiar with all the major elements of the New Zealand flora, and will be able to work with any modern Flora to key out and identify plants from the scientific literature.  The paper will normally be taught entirely over two weeks in February. [normally held every alternate year - 'odd' years].

(Pre-enrolment form)

BIOL227 - Flora of the Pacific

A paper for students interested and interested people in the flora of the Pacific, with an emphasis on identification of plants, plant systematics and biogeography.  A field trip to study a selected Pacific flora will normally be held as part of this paper.

 

At the end of this paper students will be familiar with all the major elements of the relevant country's flora, and will be able to work with any modern Flora to key out and identify plants from the scientific literature.  The dates for this paper will normally be taught entirely over two weeks in February.  [normally held every alternate year - 'even' years].

 

BIOL310 - Advanced Genetics [click on the link to see what the students have been up to]

 

This paper follows on from BIOL210 and deals in greater detail with both the molecular and whole organism aspects of genetics.  Throughout the paper there will be an emphasis on the application of genetic knowledge; on the one hand in the direction of genetic engineering and genetic analysis and on the other hand in the study of population genetics. 

 

The paper is recommended to all biologists; it complements papers both in the evolutionary areas of biology as well as those in the metabolic and biotechnological.

Field Trips:
Laboratory BIOL226 and BIOL227 have a field trip component built into each course.  COMING SOON! - a visual display of students and staff in the field.
Graduate Level:
BIOL521 - Plant Ecology -

This course examines aspects of the adaptation of plants to their environment and the structure and functioning of plant communities.  Early sessions cover ecological genetics including conservation genetics. Demography and regeneration dynamics of plant populations are followed by consideration of patterns and processes of change (succession) and vegetation assessments techniques.  Plant invasions (weed biology) and specialist techniques of spatial analysis and modelling are then considered and the final sessions focus on restoration ecology.
