Pre-requisites

BI 2001 or BI 20P1

Overview

This course covers the floristic regions of the world and, in particular, the biogeography of the Northern hemisphere. Special emphasis is given to the floras of Europe and the Mediterranean region. Discontinuous plant distributions, localised distributions and island floras are examined. The origin and evolution of the flora of the Mediterranean region is related to climate change. The course shows how British vegetation can be classified and gives practical experience of identification using the National Vegetation Classification scheme and MATCH computer programme. Resources for conservation are examined, including the role of botanic gardens and herbaria. UK Species Action Plans and the importance of biological information for successful species conservation is also discussed.

Structure

Thread I: 6 week course, 3 one-hour lectures per week and six hours per week of field trips, fieldwork and tutorials.

To pass this course, a pass must be achieved in BOTH the theory exam and the in-course assessment.

Assessment

1st Attempt: 1 two-hour examination (67%) and in-course assessment (33%).

Resit: 1 two-hour written examination for all candidates and a 1 hour examination on in-course material for those who failed this assessment.

Dr J McDonald

Pre-requisites

BI 20P1 or BI 25P1. Other students may be admitted to the course at the discretion of the Head of School.

Overview

This course covers some major topics relating to plant survival and growth in different environments. It considers adaptations that have occurred in the evolution of plant structure and function with particular reference to morphological and physiological aspects pertaining to plant survival and efficiency of resource capture and use. The course comprises lectures, workshops and field excursions to coastal and woodland habitats.

Structure

6 week course, Thread II. Teaching hours vary with activity throughout the course (mostly lectures and workshops to begin with, followed by field excursions later in course).

To pass this course, a pass must be achieved in BOTH the theory exam and the in-course assessment.

Assessment

1st Attempt: 1 two-hour written examination (67%) and in-course assessment (33%) comprising 4 reports.

Resit: A two hour written exam for all candidates.

Dr S Woodward

Pre-requisites

BI 25P1, BI 1508 or BI 2505 or appropriate Level 2 Biology. Other students may be admitted to the course at the discretion of the Head of School.

Overview

This course will begin with an Introduction to Plant Pathology (causes/symptoms of disease; pathogens and pathogenesis, historical background, significance and impact of disease; pathogen structure and function, spread and survival). It will then discuss the following topics: Molecular methods in plant pathology (application of molecular techniques to detect and understand the biology of plant pathogens in managed ecosystems, the advantages and limitations of the methods); Host-Pathogen-Environment Interactions (Plant stresses and disease susceptibility; host-pathogen interactions in managed ecosystems); Plant defence mechanisms and disease control (Resistance Genes; Plant defence mechanisms including induced resistance, Nematode disease control; Microbial biocontrol; Biological crop protection for control of insect pests; General principals of crop management); Potato Pathogens: Understanding their interactions. The final week of the course will consist of lectures from specialists who work at the research and farmer level (both in-house and with visiting speakers) on the wide array of potato diseases to provide in-depth information and concomitantly show how a broad understanding of the host, the pathogen/pest and their environments is required in order to control disease.

Structure

Thread II: 6 week course: 6 one-hour lectures per week, 2-3 hours from Visiting Speakers, 3 tutorials per course in-course assessment.

Assessment

1st Attempt: 1 two-hour written examination (70%); continuous assessment (30%).

Resit: 1 two-hour written examination (70%); continuous assessment (30%).
