Social Stress in the Fieldvole: Differential Causes of Death in Relation to Behaviour and Social Structure
Abstract and Summary The fieldvole ( Microtus arvalis ) undergoes population density fluctuations associated with mass deaths at high densities. The causes of these mass deaths have not yet been fully explained although hypoglycaemic shock can account for a proportion of them. The study investigates...
