Unit Information

Why is this unit important?

Animals interact with and affect their world via behaviour, and behavioural decisions are based on an animal’s perception of sensory information. In turn, animals are affected by the behaviour of other animals – predators, prey, parasites, mates, rivals. So, whether one’s goal is to explain animal ‘design’, ecology or evolution, or to conserve species, manage livestock or repel pests, you need to understand behaviour and how animals experience their worlds. In this unit, we explore these topics from a multidisciplinary perspective, applying the concepts and methodologies from traditionally different fields, to link sensory biology to behavioural ecology, population ecology and evolution.

How does this unit fit into your programme of study?

In all our biology degrees, the core knowledge and skills are delivered in years 1 and 2. Year 3 lecture units serve progression towards being a subject-specific expert in areas of biology of interest. Bristol is world-leading in the study of behaviour and sensory ecology, and this unit immerses you in cutting-edge research, either with a view to a research career in this area, for progression directly to a specialised job, or to support a broader portfolio of biological interests. Importantly, the unit also serves as the ‘raw material’ for a more general development of critical skills sought-after by employers well beyond biology.

Your learning on this unit

An overview of content

Almost all animals face the problem of getting enough food while avoiding being eaten, which is a major force in the evolution of animal senses, neuroethology and behaviour. This unit concerns the vast array of adaptations that animals have evolved to maximise their survival, from how they perceive their world to how they use this information to make adaptive decisions. Focus will be on predator-prey interactions, but the unit will also draw on herbivory, pollination, and placing trophic adaptations in the context of other conflicting demands on animals, such as sex and caring for offspring.

How will students, personally, be different as a result of the unit

At the end of the unit, you will have been taken to the edge of knowledge in a rapidly advancing field, one in which Bristol is a world leader. You will understand the advantages of interdisciplinary research and how technological breakthroughs are often the drivers for new understanding of old and important problems. You will also see the personal value of being able to straddle traditionally different fields, increasing your employability.

Learning outcomes

On completion, students should be able to:

  1. Explain the general theoretical principles underlying survival strategies, and how individual behaviour and perception has consequences at larger (ecological and evolutionary) scales.
  2. Evaluate the strength of evidence presented in scientific papers relevant to the theories covered in the unit.
  3. Apply their knowledge, supported by appropriate examples from the scientific literature, to propose and explain hypotheses that might explain novel scenarios.
  4. Apply their knowledge to propose tests for hypotheses, with justifications for their choices.

How you will learn

Core knowledge, including explanation of underpinning theory, research approaches, supporting evidence and current controversies, will be largely delivered via lectures, backed up by directed reading. Lectures will be traditional or ‘flipped’ as appropriate to the topic at hand. The application of the scientific method to problem-solving within the field will be developed through structured discussion classes. There is a strong expectation of independent reading, with the emphasis on the quality, not quantity, of material identified by students.

How you will be assessed

Tasks which help you learn and prepare you for summative tasks (formative):

The assessments for the unit are designed to test programme-level cognitive and presentation skills expected of graduate biologists, but in the context of the specific knowledge, theory and scientific arguments surrounding the topics taught in this unit. As such, it draws on core knowledge and generic skills acquired in years 1 and 2 of the degree programme: the ability to research a scientific topic using traditional and online library resources, the ability to evaluate evidence critically and compare competing hypotheses, the ability to generate hypotheses for observed phenomena and to propose ways to test competing hypotheses, the ability to identify gaps in knowledge and propose ways to fill those gaps, the ability to present evidence-based arguments for one or more propositions, in a reasoned, professional manner. The ability to search and evaluate the scientific literature efficiently will have been enhanced by the units in TB1, particularly the Literature Review (BIOL30002). To help students apply these skills in a subject-specific way, in addition to lectures and directed reading, there are discussion classes focused on the qualities that the summative assessments expect students to possess: hypothesis generation, critical analysis, experimental design (and selection of appropriate research methods more generally), and clear, concise explanation. These discussion classes are interspersed between groups of lectures across the unit, allowing students to build progressively their critical abilities (and confidence in applying them). The discussions will be in-person, but utilise online discussion boards (e.g. Padlets) to provide a permanent record for student reference, and the opportunity for lecturers to correct misunderstandings or expand on explanations.

Tasks which count towards your unit mark (summative):

The unit mark is based on:

  • 30% Structured critical evaluation of a specified piece of scientific communication (e.g. paper, report), carried out open-book over a period of 4 days at the mid-point of the unit.
  • 70% Essay-format, word-limited, upload / download exam carried out open book over a period of 3 h during the university summer assessment period.

When assessment does not go to plan:

Normally, if the structured critical evaluation of a specified scientific paper is missed, the same assessment task will be set with an alternative paper and question, at a time to be determined in consultation with the Senior Tutor’s team. If the exam is missed, an alternative paper will normally be set in the reassessment period.

Resources

If this unit has a Resource List, you will normally find a link to it in the Blackboard area for the unit. Sometimes there will be a separate link for each weekly topic.

If you are unable to access a list through Blackboard, you can also find it via the Resource Lists homepage. Search for the list by the unit name or code (e.g. BIOL30024).

How much time the unit requires
Each credit equates to 10 hours of total student input. For example a 20 credit unit will take you 200 hours of study to complete. Your total learning time is made up of contact time, directed learning tasks, independent learning and assessment activity.

See the University Workload statement relating to this unit for more information.

Assessment
The Board of Examiners will consider all cases where students have failed or not completed the assessments required for credit. The Board considers each student's outcomes across all the units which contribute to each year's programme of study. For appropriate assessments, if you have self-certificated your absence, you will normally be required to complete it the next time it runs (for assessments at the end of TB1 and TB2 this is usually in the next re-assessment period).
The Board of Examiners will take into account any exceptional circumstances and operates within the Regulations and Code of Practice for Taught Programmes.
