TLDR
A metapopulation approach is needed that integrates captive and wild-living island and peninsula (disease suppression) populations to minimize the loss of genetic diversity over 50 years until either extinction and reintroduction can occur, resistance evolves or a field-deliverable vaccine is developed. Expand
Daily activity of impala
TLDR
The presence of females in his territory disturbs the basic activity pattern of the territorial male, reducing his time spent on feeding and ruminating and the relationship between the occurrence of males in shade and some environmental factors is analysed. Expand
Prey synchronize their vigilant behaviour with other group members
TLDR
The results confirmed that the proportion of time an individual spent in vigilance decreased with group size, but the time during which at least one individual in the group scanned the environment (collective vigilance) increased, and it was claimed that these waves are triggered by allelomimetic effects i.e. an individual copying its neighbour's behaviour.
