Question 1

Threatened species lists fulfil social, political and scientific needs. but have many limitations is actually dealing effectively with the issues they present -uneven taxonomic treatment -variation in observational effort -changes may merely represent change in knowledge

Answer 1

Question 13

Male badgers appear to experience more adverse effects of infection of TB compared to females. Could be behavioural, immune function and/or reproduction Culling needs to be over 150km2 for 5 years to reduce incidence by ~12% Gassing burrows in Thornbury over several years lead to sustained absence of TB but cost and effort are very high
