Understanding the Biodiversity Crisis: Introduction to Ecology and Conservation

Overview

The biodiversity crisis represents one of the most pressing challenges of our time, with ecosystems facing unprecedented rates of species loss. This course provides students with an introduction to the fundamental principles of ecology and the principles and practices of conservation biology.

We will look at a range of different habitats and organisms to gain an understanding of how species and communities, as well as their interactions, are shaped by the environment they inhabit. Our focus ranges from the individual species and populations all the way up to interactions among all the species within a habitat. We will also gain an understanding of the threats facing species and ecosystems, and discuss how conservation biology offers at least partial mitigations for some of these threats including looking at the role of rewilding, breeding in zoos, and species reintroductions.

We will finish the course with two case studies that integrate all of the different practices and theories covered in the course. The first will look at the challenging environmental conditions facing the animals and plants inhabiting extreme environments such as the polar regions, the deserts, and the deepest parts of our oceans, before discussing some of the wonderful ecological adaptations that these organisms have evolved to survive and thrive in these inhospitable places. In the second case study, we will look at the unique ecology and threats facing animals and plants inhabiting remote islands, where invasive species and habitat destruction have an even stronger impact than on the mainland, as island endemics have nowhere to escape to.

Certification

Credit Application Transfer Scheme (CATS) points 

To earn credit (CATS points) for your course you will need to register and pay an additional £30 fee for each course you enrol on. You can do this by ticking the relevant box at the bottom of the enrolment form or when enrolling online. If you do not register when you enrol, you have up until the course start date to register and pay the £30 fee. 

See more information on CATS point

Coursework is an integral part of all online courses and everyone enrolled will be expected to do coursework, but only those who have registered for credit will be awarded CATS points for completing work at the required standard. If you are enrolled on the Certificate of Higher Education, you need to indicate this on the enrolment form but there is no additional registration fee. 

 

Digital credentials

All students who pass their final assignment, whether registered for credit or not, will be eligible for a digital Certificate of Completion. Upon successful completion, you will receive a link to download a University of Oxford digital certificate. Information on how to access this digital certificate will be emailed to you after the end of the course. The certificate will show your name, the course title and the dates of the course you attended. You will be able to download your certificate or share it on social media if you choose to do so. 

Please note that assignments are not graded but are marked either pass or fail.

Tutor

Dr Thomas Hesselberg

Thomas is a zoologist and behavioural ecologists who has studied spiders, insects and worms for more than 15 years in both temperate and tropical climates. He is course-director for the department's PgCert in Ecological Survey Techniques, and, in addition to his teaching for the Department for Continuing Education, he is a lecturer in biological sciences at St. Anne's College.

Course aims

To equip students to understand the basic principles and concepts of ecology, the importance of biodiversity and how to mitigate for the many anthropegenic threats facing natural ecosystems and the species inhabiting them.

Course objectives:

  • To introduce students to the principles and concepts of ecology, including ecosystem dynamics, species interactions, and biodiversity surveying techniques.
  • To encourage critical thinking and problem-solving skills in relation to ecological surveying and biodiversity conservation by equipping student with the skills to find and interpret the relevant scientific literature.

Teaching methods

The teaching methods consists of 1 hour of pre-recorded lectures and 1 hour of live interactive discussions and activities per week. 

Learning outcomes

By the end of the course students will be expected to:

  • Identify the major causes and drivers of the current biodiversity crisis, including habitat loss, climate change, pollution, overexploitation, and invasive species and recognise how the relative importance of these drivers vary with habitat.
  • Apply ecological and conservation concepts to real-world scenarios and case studies, demonstrating an understanding of how theory translates into practicem while critically engaging with relevant scientific literature.
  • Understand and apply the scientific method and ecological survey techniques to monitor biodiversity and population changes in different ecosystems.

Assessment methods

Write an 1500 word essay on the ecology and conservation of a nature reserve or national park of you own choosing or on the ecology and conservation of a specific group of organisms of your own choosing

OR

Write a 1500 word brief field report (including the following sections; introduction, methods, results and conclusion) based on a biodiversity survey that you have conducted in a local nature reserve of your own choosing.

Coursework is an integral part of all weekly classes and everyone enrolled will be expected to do coursework in order to benefit fully from the course. Only those who have registered for credit will be awarded CATS points for completing work the required standard.

Students must submit a completed Declaration of Authorship form at the end of term when submitting your final piece of work. CATS points cannot be awarded without the aforementioned form - Declaration of Authorship form

Application

We will close for enrolments 14 days prior to the start date to allow us to complete the course set up. We will email you at that time (14 days before the course begins) with further information and joining instructions. As always, students will want to check spam and junk folders during this period to ensure that these emails are received.

To earn credit (CATS points) for your course you will need to register and pay an additional £30 fee per course. You can do this by ticking the relevant box at the bottom of the enrolment form or when enrolling online.

Please use the 'Book' or 'Apply' button on this page. Alternatively, please complete an Enrolment Form (Word) or Enrolment Form (Pdf)

Level and demands

The Department's Weekly Classes are taught at FHEQ Level 4, i.e. first year undergraduate level, and you will be expected to engage in a significant amount of private study in preparation for the classes. This may take the form, for instance, of reading and analysing set texts, responding to questions or tasks, or preparing work to present in class.

Credit Accumulation and Transfer Scheme (CATS)

To earn credit (CATS points) you will need to register and pay an additional £30 fee per course. You can do this by ticking the relevant box at the bottom of the enrolment form or when enrolling online. Students who register for CATS points will receive a Record of CATS points on successful completion of their course assessment.

Students who do not register for CATS points during the enrolment process can either register for CATS points prior to the start of their course or retrospectively from the January 1st after the current full academic year has been completed. If you are enrolled on the Certificate of Higher Education you need to indicate this on the enrolment form but there is no additional registration fee.
