The Times Higher Education World University Rankings 2016-2017 life sciences subject ranking includes a wide range of narrower subject areas.

The list of subjects used to create this ranking is:

• Agriculture & Forestry
• Biological Sciences
• Veterinary Science
• Sport Science

The subject tables employ the same range of?13 performance indicators?used in the overall World University Rankings 2016-2017, brought together with scores provided under five categories.

However, the overall methodology is carefully recalibrated for each subject, with the weightings changed to suit the individual fields.

The weightings for the life sciences ranking are:

• Teaching:?the learning environment
  27.5 per cent
• Research:?volume, income and reputation
  27.5 per cent
• Citations:?research influence
  35 per cent
• International outlook:?staff, students and research
  7.5 per cent
• Industry income:?innovation
  2.5 per cent

No institution can be included in the overall World University Rankings unless it?has published a minimum of 200 research papers a year over the five years we examine.

But for the eight subject tables, the threshold drops to 100 papers a year for subjects that generate a high volume of publications and 50 a year in subjects such as social sciences where the volume tends to be lower. Although we apply some editorial discretion, we generally expect an institution to have at least 5 per cent of its staff working in the relevant discipline in order to include it in the subject table.

In rare cases where such data are not supplied, institutions are either excluded or public sources are used to underpin estimates.
