Introduction to research methodology

This post is an introduction to cetacean research methodology, where there is a list of different methods and what you can study with them. En the following publications, you will find an specific information of each one.

 

The study of cetaceans at sea consists on the study of its ecology, like an individual (feeding, social and reproductive behaviour) and like a group (space and time’s distribution, abundance and population tendencies). There are different methods to study cetaceans in theses different aspects:

1) Observations: you can study the abundance and distribution.

2) Acoustic research methods: you can study the distribution, abundance and feeding and reproductive behaviour.

3) Individual identification (Photo-identification and mark-recapture): you are able to study the abundance, movements, reproduction and survival.

4) Satellite tagging: you can study the movements, feeding behaviour and survivial.

5) Genetic methods: you are able to study the reproduction, genetics and diet.

6) Geographic Information Systems: you can study the area use, density, feeding and reproduction zones, movements and conservation.
